By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs.

There are several ways to run +such a walker. + +**simple**`(node, visitors, base, state)` does a 'simple' walk over a +tree. `node` should be the AST node to walk, and `visitors` an object +with properties whose names correspond to node types in the [ESTree +spec](https://github.com/estree/estree). The properties should contain +functions that will be called with the node object and, if applicable +the state at that point. The last two arguments are optional. `base` +is a walker algorithm, and `state` is a start state. The default +walker will simply visit all statements and expressions and not +produce a meaningful state. (An example of a use of state is to track +scope at each point in the tree.) + +```js +const acorn = require("acorn") +const walk = require("acorn-walk") + +walk.simple(acorn.parse("let x = 10"), { + Literal(node) { + console.log(`Found a literal: ${node.value}`) + } +}) +``` + +**ancestor**`(node, visitors, base, state)` does a 'simple' walk over +a tree, building up an array of ancestor nodes (including the current node) +and passing the array to the callbacks as a third parameter. + +```js +const acorn = require("acorn") +const walk = require("acorn-walk") + +walk.ancestor(acorn.parse("foo('hi')"), { + Literal(_, ancestors) { + console.log("This literal's ancestors are:", ancestors.map(n => n.type)) + } +}) +``` + +**recursive**`(node, state, functions, base)` does a 'recursive' +walk, where the walker functions are responsible for continuing the +walk on the child nodes of their target node. `state` is the start +state, and `functions` should contain an object that maps node types +to walker functions.

The +`input` parameter is a string, `options` can be undefined or an object +setting some of the options listed below. The return value will be an +abstract syntax tree object as specified by the [ESTree +spec](https://github.com/estree/estree). + +```javascript +let acorn = require("acorn"); +console.log(acorn.parse("1 + 1")); +``` + +When encountering a syntax error, the parser will raise a +`SyntaxError` object with a meaningful message. The error object will +have a `pos` property that indicates the string offset at which the +error occurred, and a `loc` object that contains a `{line, column}` +object referring to that same position. + +Options can be provided by passing a second argument, which should be +an object containing any of these fields: + +- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be + either 3, 5, 6 (2015), 7 (2016), 8 (2017), 9 (2018), 10 (2019) or 11 + (2020, partial support). This influences support for strict mode, + the set of reserved words, and support for new syntax features. + Default is 10. + + **NOTE**: Only 'stage 4' (finalized) ECMAScript features are being + implemented by Acorn. Other proposed new features can be implemented + through plugins. + +- **sourceType**: Indicate the mode the code should be parsed in. Can be + either `"script"` or `"module"`. This influences global strict mode + and parsing of `import` and `export` declarations. + + **NOTE**: If set to `"module"`, then static `import` / `export` syntax + will be valid, even if `ecmaVersion` is less than 6. + +- **onInsertedSemicolon**: If given a callback, that callback will be + called whenever a missing semicolon is inserted by the parser. The + callback will be given the character offset of the point where the + semicolon is inserted as argument, and if `locations` is on, also a + `{line, column}` object representing this position. + +- **onTrailingComma**: Like `onInsertedSemicolon`, but for trailing + commas. + +- **allowReserved**: If `false`, using a reserved word will generate + an error. Defaults to `true` for `ecmaVersion` 3, `false` for higher + versions. When given the value `"never"`, reserved words and + keywords can also not be used as property names (as in Internet + Explorer's old parser). + +- **allowReturnOutsideFunction**: By default, a return statement at + the top level raises an error. Set this to `true` to accept such + code. + +- **allowImportExportEverywhere**: By default, `import` and `export` + declarations can only appear at a program's top level. Setting this + option to `true` allows them anywhere where a statement is allowed. + +- **allowAwaitOutsideFunction**: By default, `await` expressions can + only appear inside `async` functions. Setting this option to + `true` allows to have top-level `await` expressions. They are + still not allowed in non-`async` functions, though. + +- **allowHashBang**: When this is enabled (off by default), if the + code starts with the characters `#!` (as in a shellscript), the + first line will be treated as a comment. + +- **locations**: When `true`, each node has a `loc` object attached + with `start` and `end` subobjects, each of which contains the + one-based line and zero-based column numbers in `{line, column}` + form. Default is `false`. + +- **onToken**: If a function is passed for this option, each found + token will be passed in same format as tokens returned from + `tokenizer().getToken()`. + + If array is passed, each found token is pushed to it. + + Note that you are not allowed to call the parser from the + callback—that will corrupt its internal state. + +- **onComment**: If a function is passed for this option, whenever a + comment is encountered the function will be called with the + following parameters: + + - `block`: `true` if the comment is a block comment, false if it + is a line comment. + - `text`: The content of the comment. + - `start`: Character offset of the start of the comment. + - `end`: Character offset of the end of the comment. + + When the `locations` options is on, the `{line, column}` locations + of the comment’s start and end are passed as two additional + parameters. + + If array is passed for this option, each found comment is pushed + to it as object in Esprima format: + + ```javascript + { + "type": "Line" | "Block", + "value": "comment text", + "start": Number, + "end": Number, + // If `locations` option is on: + "loc": { + "start": {line: Number, column: Number} + "end": {line: Number, column: Number} + }, + // If `ranges` option is on: + "range": [Number, Number] + } + ``` + + Note that you are not allowed to call the parser from the + callback—that will corrupt its internal state. + +- **ranges**: Nodes have their start and end characters offsets + recorded in `start` and `end` properties (directly on the node, + rather than the `loc` object, which holds line/column data. To also + add a + [semi-standardized](https://bugzilla.mozilla.org/show_bug.cgi?id=745678) + `range` property holding a `[start, end]` array with the same + numbers, set the `ranges` option to `true`. + +- **program**: It is possible to parse multiple files into a single + AST by passing the tree produced by parsing the first file as the + `program` option in subsequent parses. This will add the toplevel + forms of the parsed file to the "Program" (top) node of an existing + parse tree. + +- **sourceFile**: When the `locations` option is `true`, you can pass + this option to add a `source` attribute in every node’s `loc` + object. Note that the contents of this option are not examined or + processed in any way; you are free to use whatever format you + choose. + +- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property + will be added (regardless of the `location` option) directly to the + nodes, rather than the `loc` object. + +- **preserveParens**: If this option is `true`, parenthesized expressions + are represented by (non-standard) `ParenthesizedExpression` nodes + that have a single `expression` property containing the expression + inside parentheses. + +**parseExpressionAt**`(input, offset, options)` will parse a single +expression in a string, and return its AST. It will not complain if +there is more of the string left after the expression. + +**tokenizer**`(input, options)` returns an object with a `getToken` +method that can be called repeatedly to get the next token, a `{start, +end, type, value}` object (with added `loc` property when the +`locations` option is enabled and `range` property when the `ranges` +option is enabled). When the token's type is `tokTypes.eof`, you +should stop calling the method, since it will keep returning that same +token forever. + +In ES6 environment, returned result can be used as any other +protocol-compliant iterable: + +```javascript +for (let token of acorn.tokenizer(str)) { + // iterate over the tokens +} + +// transform code to array of tokens: +var tokens = [...acorn.tokenizer(str)]; +``` + +**tokTypes** holds an object mapping names to the token type objects +that end up in the `type` properties of tokens. + +**getLineInfo**`(input, offset)` can be used to get a `{line, +column}` object for a given program string and offset. + +### The `Parser` class + +Instances of the **`Parser`** class contain all the state and logic +that drives a parse. It has static methods `parse`, +`parseExpressionAt`, and `tokenizer` that match the top-level +functions by the same name. + +When extending the parser with plugins, you need to call these methods +on the extended version of the class. To extend a parser with plugins, +you can use its static `extend` method. + +```javascript +var acorn = require("acorn"); +var jsx = require("acorn-jsx"); +var JSXParser = acorn.Parser.extend(jsx()); +JSXParser.parse("foo()"); +``` + +The `extend` method takes any number of plugin values, and returns a +new `Parser` class that includes the extra parser logic provided by +the plugins. + +## Command line interface + +The `bin/acorn` utility can be used to parse a file from the command +line. It accepts as arguments its input file and the following +options: + +- `--ecma3|--ecma5|--ecma6|--ecma7|--ecma8|--ecma9|--ecma10`: Sets the ECMAScript version + to parse. Default is version 9. + +- `--module`: Sets the parsing mode to `"module"`.

All +middlewares will populate the `req.body` property with the parsed body when +the `Content-Type` request header matches the `type` option, or an empty +object (`{}`) if there was no body to parse, the `Content-Type` was not matched, +or an error occurred. + +The various errors returned by this module are described in the +[errors section](#errors). + +### bodyParser.json([options]) + +Returns middleware that only parses `json` and only looks at requests where +the `Content-Type` header matches the `type` option. This parser accepts any +Unicode encoding of the body and supports automatic inflation of `gzip` and +`deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). + +#### Options + +The `json` function takes an optional `options` object that may contain any of +the following keys: + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected.

Defaults to `true`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a string, array of strings, or a function. If not a +function, `type` option is passed directly to the +[type-is](https://www.npmjs.org/package/type-is#readme) library and this can +be an extension name (like `json`), a mime type (like `application/json`), or +a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type` +option is called as `fn(req)` and the request is parsed if it returns a truthy +value. Defaults to `application/json`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request.

The parsing can be aborted by throwing an error. + +### bodyParser.urlencoded([options]) + +Returns middleware that only parses `urlencoded` bodies and only looks at +requests where the `Content-Type` header matches the `type` option. This +parser accepts only UTF-8 encoding of the body and supports automatic +inflation of `gzip` and `deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). This object will contain +key-value pairs, where the value can be a string or array (when `extended` is +`false`), or any type (when `extended` is `true`). + +#### Options + +The `urlencoded` function takes an optional `options` object that may contain +any of the following keys: + +##### extended + +The `extended` option allows to choose between parsing the URL-encoded data +with the `querystring` library (when `false`) or the `qs` library (when +`true`). The "extended" syntax allows for rich objects and arrays to be +encoded into the URL-encoded format, allowing for a JSON-like experience +with URL-encoded. For more information, please +[see the qs library](https://www.npmjs.org/package/qs#readme). + +Defaults to `true`, but using the default has been deprecated. Please +research into the difference between `qs` and `querystring` and choose the +appropriate setting. + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### parameterLimit + +The `parameterLimit` option controls the maximum number of parameters that +are allowed in the URL-encoded data. If a request contains more parameters +than this value, a 413 will be returned to the client. Defaults to `1000`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a string, array of strings, or a function. If not +a function, `type` option is passed directly to the +[type-is](https://www.npmjs.org/package/type-is#readme) library and this can +be an extension name (like `urlencoded`), a mime type (like +`application/x-www-form-urlencoded`), or a mime type with a wildcard (like +`*/x-www-form-urlencoded`). If a function, the `type` option is called as +`fn(req)` and the request is parsed if it returns a truthy value. Defaults +to `application/x-www-form-urlencoded`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +## Errors + +The middlewares provided by this module create errors using the +[`http-errors` module](https://www.npmjs.com/package/http-errors). The errors +will typically have a `status`/`statusCode` property that contains the suggested +HTTP response code, an `expose` property to determine if the `message` property +should be displayed to the client, a `type` property to determine the type of +error without matching against the `message`, and a `body` property containing +the read body, if available. + +The following are the common errors created, though any error can come through +for various reasons. + +### content encoding unsupported + +This error will occur when the request had a `Content-Encoding` header that +contained an encoding but the "inflation" option was set to `false`. The +`status` property is set to `415`, the `type` property is set to +`'encoding.unsupported'`, and the `charset` property will be set to the +encoding that is unsupported. + +### entity parse failed + +This error will occur when the request contained an entity that could not be +parsed by the middleware. The `status` property is set to `400`, the `type` +property is set to `'entity.parse.failed'`, and the `body` property is set to +the entity value that failed parsing. + +### entity verify failed + +This error will occur when the request contained an entity that could not be +failed verification by the defined `verify` option. The `status` property is +set to `403`, the `type` property is set to `'entity.verify.failed'`, and the +`body` property is set to the entity value that failed verification. + +### request aborted + +This error will occur when the request is aborted by the client before reading +the body has finished. The `received` property will be set to the number of +bytes received before the request was aborted and the `expected` property is +set to the number of expected bytes. The `status` property is set to `400` +and `type` property is set to `'request.aborted'`. + +### request entity too large + +This error will occur when the request body's size is larger than the "limit" +option. The `limit` property will be set to the byte limit and the `length` +property will be set to the request body's length. The `status` property is +set to `413` and the `type` property is set to `'entity.too.large'`. + +### request size did not match content length + +This error will occur when the request's length did not match the length from +the `Content-Length` header. This typically occurs when the request is malformed, +typically when the `Content-Length` header was calculated based on characters +instead of bytes. The `status` property is set to `400` and the `type` property +is set to `'request.size.invalid'`. + +### stream encoding should not be set + +This error will occur when something called the `req.setEncoding` method prior +to this middleware. This module operates directly on bytes only and you cannot +call `req.setEncoding` when using this module. The `status` property is set to +`500` and the `type` property is set to `'stream.encoding.set'`. + +### stream is not readable + +This error will occur when the request is no longer readable when this middleware +attempts to read it. This typically means something other than a middleware from +this module read the reqest body already and the middleware was also configured to +read the same request. The `status` property is set to `500` and the `type` +property is set to `'stream.not.readable'`. + +### too many parameters + +This error will occur when the content of the request exceeds the configured +`parameterLimit` for the `urlencoded` parser. The `status` property is set to +`413` and the `type` property is set to `'parameters.too.many'`. + +### unsupported charset "BOGUS" + +This error will occur when the request had a charset parameter in the +`Content-Type` header, but the `iconv-lite` module does not support it OR the +parser does not support it. The charset is contained in the message as well +as in the `charset` property. The `status` property is set to `415`, the +`type` property is set to `'charset.unsupported'`, and the `charset` property +is set to the charset that is unsupported. + +### unsupported content encoding "bogus" + +This error will occur when the request had a `Content-Encoding` header that +contained an unsupported encoding. The encoding is contained in the message +as well as in the `encoding` property. The `status` property is set to `415`, +the `type` property is set to `'encoding.unsupported'`, and the `encoding` +property is set to the encoding that is unsupported. + +## Examples + +### Express/Connect top-level generic + +This example demonstrates adding a generic JSON and URL-encoded parser as a +top-level middleware, which will parse the bodies of all incoming requests. +This is the simplest setup. + +```js +var express = require('express') +var bodyParser = require('body-parser') + +var app = express() + +// parse application/x-www-form-urlencoded +app.use(bodyParser.urlencoded({ extended: false })) + +// parse application/json +app.use(bodyParser.json()) + +app.use(function (req, res) { + res.setHeader('Content-Type', 'text/plain') + res.write('you posted:\n') + res.end(JSON.stringify(req.body, null, 2)) +}) +``` + +### Express route-specific + +This example demonstrates adding body parsers specifically to the routes that +need them.

In other words: + +* [brace expansion](#brace-expansion) is for generating new lists +* [brace matching](#brace-matching) is for filtering existing lists + +
+More about brace expansion (click to expand) + +There are two main types of brace expansion: + +1. **lists**: which are defined using comma-separated values inside curly braces: `{a,b,c}` +2. **sequences**: which are defined using a starting value and an ending value, separated by two dots: `a{1..3}b`. Optionally, a third argument may be passed to define a "step" or increment to use: `a{1..100..10}b`. These are also sometimes referred to as "ranges". + +Here are some example brace patterns to illustrate how they work: + +**Sets** + +``` +{a,b,c} => a b c +{a,b,c}{1,2} => a1 a2 b1 b2 c1 c2 +``` + +**Sequences** + +``` +{1..9} => 1 2 3 4 5 6 7 8 9 +{4..-4} => 4 3 2 1 0 -1 -2 -3 -4 +{1..20..3} => 1 4 7 10 13 16 19 +{a..j} => a b c d e f g h i j +{j..a} => j i h g f e d c b a +{a..z..3} => a d g j m p s v y +``` + +**Combination** + +Sets and sequences can be mixed together or used along with any other strings. + +``` +{a,b,c}{1..3} => a1 a2 a3 b1 b2 b3 c1 c2 c3 +foo/{a,b,c}/bar => foo/a/bar foo/b/bar foo/c/bar +``` + +The fact that braces can be "expanded" from relatively simple patterns makes them ideal for quickly generating test fixtures, file paths, and similar use cases. + +## Brace matching + +In addition to _expansion_, brace patterns are also useful for performing regular-expression-like matching. + +For example, the pattern `foo/{1..3}/bar` would match any of following strings: + +``` +foo/1/bar +foo/2/bar +foo/3/bar +``` + +But not: + +``` +baz/1/qux +baz/2/qux +baz/3/qux +``` + +Braces can also be combined with [glob patterns](https://github.com/jonschlinkert/micromatch) to perform more advanced wildcard matching. For example, the pattern `*/{1..3}/*` would match any of following strings: + +``` +foo/1/bar +foo/2/bar +foo/3/bar +baz/1/qux +baz/2/qux +baz/3/qux +``` + +## Brace matching pitfalls + +Although brace patterns offer a user-friendly way of matching ranges or sets of strings, there are also some major disadvantages and potential risks you should be aware of. + +### tldr + +**"brace bombs"** + +* brace expansion can eat up a huge amount of processing resources +* as brace patterns increase _linearly in size_, the system resources required to expand the pattern increase exponentially +* users can accidentally (or intentially) exhaust your system's resources resulting in the equivalent of a DoS attack (bonus: no programming knowledge is required!) + +For a more detailed explanation with examples, see the [geometric complexity](#geometric-complexity) section. + +### The solution + +Jump to the [performance section](#performance) to see how Braces solves this problem in comparison to other libraries. + +### Geometric complexity + +At minimum, brace patterns with sets limited to two elements have quadradic or `O(n^2)` complexity. But the complexity of the algorithm increases exponentially as the number of sets, _and elements per set_, increases, which is `O(n^c)`. + +For example, the following sets demonstrate quadratic (`O(n^2)`) complexity: + +``` +{1,2}{3,4} => (2X2) => 13 14 23 24 +{1,2}{3,4}{5,6} => (2X2X2) => 135 136 145 146 235 236 245 246 +``` + +But add an element to a set, and we get a n-fold Cartesian product with `O(n^c)` complexity: + +``` +{1,2,3}{4,5,6}{7,8,9} => (3X3X3) => 147 148 149 157 158 159 167 168 169 247 248 + 249 257 258 259 267 268 269 347 348 349 357 + 358 359 367 368 369 +``` + +Now, imagine how this complexity grows given that each element is a n-tuple: + +``` +{1..100}{1..100} => (100X100) => 10,000 elements (38.4 kB) +{1..100}{1..100}{1..100} => (100X100X100) => 1,000,000 elements (5.76 MB) +``` + +Although these examples are clearly contrived, they demonstrate how brace patterns can quickly grow out of control. + +**More information** + +Interested in learning more about brace expansion? + +* [linuxjournal/bash-brace-expansion](http://www.linuxjournal.com/content/bash-brace-expansion) +* [rosettacode/Brace_expansion](https://rosettacode.org/wiki/Brace_expansion) +* [cartesian product](https://en.wikipedia.org/wiki/Cartesian_product) + +
+ +## Performance + +Braces is not only screaming fast, it's also more accurate the other brace expansion libraries. + +### Better algorithms + +Fortunately there is a solution to the ["brace bomb" problem](#brace-matching-pitfalls): _don't expand brace patterns into an array when they're used for matching_. + +Instead, convert the pattern into an optimized regular expression.

You should find that `parseUntil` is a better choice for your task. + +### `parseUntil` + +The default behavior when the delimiter is a bracket has been changed so that nesting is taken into account to determine if the end is reached. + +To preserve the original behavior, pass `ignoreNesting: true` as an option. + +To see the difference between the new and old behaviors, see the "Usage" section earlier. + +### `parseMaxBracket` + +This function has been merged into `parseUntil`. You can directly rename the function call without any repercussions. + +## License + +MIT diff --git a/src/node_modules/character-parser/index.js b/src/node_modules/character-parser/index.js new file mode 100644 index 0000000..3623aab --- /dev/null +++ b/src/node_modules/character-parser/index.js @@ -0,0 +1,296 @@ +'use strict'; + +var objIsRegex = require('is-regex'); + +exports = (module.exports = parse); + +var TOKEN_TYPES = exports.TOKEN_TYPES = { + LINE_COMMENT: '//', + BLOCK_COMMENT: '/**/', + SINGLE_QUOTE: '\'', + DOUBLE_QUOTE: '"', + TEMPLATE_QUOTE: '`', + REGEXP: '//g' +} + +var BRACKETS = exports.BRACKETS = { + '(': ')', + '{': '}', + '[': ']' +}; +var BRACKETS_REVERSED = { + ')': '(', + '}': '{', + ']': '[' +}; + +exports.parse = parse; +function parse(src, state, options) { + options = options || {}; + state = state || exports.defaultState(); + var start = options.start || 0; + var end = options.end || src.length; + var index = start; + while (index < end) { + try { + parseChar(src[index], state); + } catch (ex) { + ex.index = index; + throw ex; + } + index++; + } + return state; +} + +exports.parseUntil = parseUntil; +function parseUntil(src, delimiter, options) { + options = options || {}; + var start = options.start || 0; + var index = start; + var state = exports.defaultState(); + while (index < src.length) { + if ((options.ignoreNesting || !state.isNesting(options)) && matches(src, delimiter, index)) { + var end = index; + return { + start: start, + end: end, + src: src.substring(start, end) + }; + } + try { + parseChar(src[index], state); + } catch (ex) { + ex.index = index; + throw ex; + } + index++; + } + var err = new Error('The end of the string was reached with no closing bracket found.'); + err.code = 'CHARACTER_PARSER:END_OF_STRING_REACHED'; + err.index = index; + throw err; +} + +exports.parseChar = parseChar; +function parseChar(character, state) { + if (character.length !== 1) { + var err = new Error('Character must be a string of length 1'); + err.name = 'InvalidArgumentError'; + err.code = 'CHARACTER_PARSER:CHAR_LENGTH_NOT_ONE'; + throw err; + } + state = state || exports.defaultState(); + state.src += character; + var wasComment = state.isComment(); + var lastChar = state.history ?

Check out our blog post about it: [Chokidar 3: How to save 32TB of traffic every week](https://paulmillr.com/posts/chokidar-3-save-32tb-of-traffic/) + +## How? + +Chokidar does still rely on the Node.js core `fs` module, but when using +`fs.watch` and `fs.watchFile` for watching, it normalizes the events it +receives, often checking for truth by getting file stats and/or dir contents. + +On MacOS, chokidar by default uses a native extension exposing the Darwin +`FSEvents` API. This provides very efficient recursive watching compared with +implementations like `kqueue` available on most \*nix platforms. Chokidar still +does have to do some work to normalize the events received that way as well. + +On most other platforms, the `fs.watch`-based implementation is the default, which +avoids polling and keeps CPU usage down. Be advised that chokidar will initiate +watchers recursively for everything within scope of the paths that have been +specified, so be judicious about not wasting system resources by watching much +more than needed. + +## Getting started + +Install with npm: + +```sh +npm install chokidar +``` + +Then `require` and use it in your code: + +```javascript +const chokidar = require('chokidar'); + +// One-liner for current directory +chokidar.watch('.').on('all', (event, path) => { + console.log(event, path); +}); +``` + +## API + +```javascript +// Example of a more typical implementation structure + +// Initialize watcher. +const watcher = chokidar.watch('file, dir, glob, or array', { + ignored: /(^|[\/\\])\../, // ignore dotfiles + persistent: true +}); + +// Something to use when events are received. +const log = console.log.bind(console); +// Add event listeners. +watcher + .on('add', path => log(`File ${path} has been added`)) + .on('change', path => log(`File ${path} has been changed`)) + .on('unlink', path => log(`File ${path} has been removed`)); + +// More possible events. +watcher + .on('addDir', path => log(`Directory ${path} has been added`)) + .on('unlinkDir', path => log(`Directory ${path} has been removed`)) + .on('error', error => log(`Watcher error: ${error}`)) + .on('ready', () => log('Initial scan complete. Ready for changes')) + .on('raw', (event, path, details) => { // internal + log('Raw event info:', event, path, details); + }); + +// 'add', 'addDir' and 'change' events also receive stat() results as second +// argument when available: https://nodejs.org/api/fs.html#fs_class_fs_stats +watcher.on('change', (path, stats) => { + if (stats) console.log(`File ${path} changed size to ${stats.size}`); +}); + +// Watch new files. +watcher.add('new-file'); +watcher.add(['new-file-2', 'new-file-3', '**/other-file*']); + +// Get list of actual paths being watched on the filesystem +var watchedPaths = watcher.getWatched(); + +// Un-watch some files. +await watcher.unwatch('new-file*'); + +// Stop watching. +// The method is async! +watcher.close().then(() => console.log('closed')); + +// Full list of options.

Paths to files, dirs to be watched +recursively, or glob patterns. + - Note: globs must not contain windows separators (`\`), + because that's how they work by the standard — + you'll need to replace them with forward slashes (`/`). + - Note 2: for additional glob documentation, check out low-level + library: [picomatch](https://github.com/micromatch/picomatch). +* `options` (object) Options object as defined below: + +#### Persistence + +* `persistent` (default: `true`). Indicates whether the process +should continue to run as long as files are being watched. If set to +`false` when using `fsevents` to watch, no more events will be emitted +after `ready`, even if the process continues to run. + +#### Path filtering + +* `ignored` ([anymatch](https://github.com/es128/anymatch)-compatible definition) +Defines files/paths to be ignored. The whole relative or absolute path is +tested, not just filename. If a function with two arguments is provided, it +gets called twice per path - once with a single argument (the path), second +time with two arguments (the path and the +[`fs.Stats`](https://nodejs.org/api/fs.html#fs_class_fs_stats) +object of that path). +* `ignoreInitial` (default: `false`). If set to `false` then `add`/`addDir` events are also emitted for matching paths while +instantiating the watching as chokidar discovers these file paths (before the `ready` event). +* `followSymlinks` (default: `true`). When `false`, only the +symlinks themselves will be watched for changes instead of following +the link references and bubbling events through the link's path. +* `cwd` (no default). The base directory from which watch `paths` are to be +derived. Paths emitted with events will be relative to this. +* `disableGlobbing` (default: `false`). If set to `true` then the strings passed to `.watch()` and `.add()` are treated as +literal path names, even if they look like globs. + +#### Performance + +* `usePolling` (default: `false`). +Whether to use fs.watchFile (backed by polling), or fs.watch. If polling +leads to high CPU utilization, consider setting this to `false`. It is +typically necessary to **set this to `true` to successfully watch files over +a network**, and it may be necessary to successfully watch files in other +non-standard situations. Setting to `true` explicitly on MacOS overrides the +`useFsEvents` default. You may also set the CHOKIDAR_USEPOLLING env variable +to true (1) or false (0) in order to override this option. +* _Polling-specific settings_ (effective when `usePolling: true`) + * `interval` (default: `100`). Interval of file system polling, in milliseconds. You may also + set the CHOKIDAR_INTERVAL env variable to override this option. + * `binaryInterval` (default: `300`). Interval of file system + polling for binary files. + ([see list of binary extensions](https://github.com/sindresorhus/binary-extensions/blob/master/binary-extensions.json)) +* `useFsEvents` (default: `true` on MacOS). Whether to use the +`fsevents` watching interface if available. When set to `true` explicitly +and `fsevents` is available this supercedes the `usePolling` setting. When +set to `false` on MacOS, `usePolling: true` becomes the default. +* `alwaysStat` (default: `false`). If relying upon the +[`fs.Stats`](https://nodejs.org/api/fs.html#fs_class_fs_stats) +object that may get passed with `add`, `addDir`, and `change` events, set +this to `true` to ensure it is provided even in cases where it wasn't +already available from the underlying watch events. +* `depth` (default: `undefined`). If set, limits how many levels of +subdirectories will be traversed. +* `awaitWriteFinish` (default: `false`). +By default, the `add` event will fire when a file first appears on disk, before +the entire file has been written. Furthermore, in some cases some `change` +events will be emitted while the file is being written. In some cases, +especially when watching for large files there will be a need to wait for the +write operation to finish before responding to a file creation or modification. +Setting `awaitWriteFinish` to `true` (or a truthy value) will poll file size, +holding its `add` and `change` events until the size does not change for a +configurable amount of time. The appropriate duration setting is heavily +dependent on the OS and hardware. For accurate detection this parameter should +be relatively high, making file watching much less responsive. +Use with caution. + * *`options.awaitWriteFinish` can be set to an object in order to adjust + timing params:* + * `awaitWriteFinish.stabilityThreshold` (default: 2000). Amount of time in + milliseconds for a file size to remain constant before emitting its event. + * `awaitWriteFinish.pollInterval` (default: 100). File size polling interval, in milliseconds. + +#### Errors + +* `ignorePermissionErrors` (default: `false`). Indicates whether to watch files +that don't have read permissions if possible. If watching fails due to `EPERM` +or `EACCES` with this set to `true`, the errors will be suppressed silently. +* `atomic` (default: `true` if `useFsEvents` and `usePolling` are `false`). +Automatically filters out artifacts that occur when using editors that use +"atomic writes" instead of writing directly to the source file. If a file is +re-added within 100 ms of being deleted, Chokidar emits a `change` event +rather than `unlink` then `add`. If the default of 100 ms does not work well +for you, you can override it by setting `atomic` to a custom value, in +milliseconds. + +### Methods & Events + +`chokidar.watch()` produces an instance of `FSWatcher`. Methods of `FSWatcher`: + +* `.add(path / paths)`: Add files, directories, or glob patterns for tracking. +Takes an array of strings or just one string. +* `.on(event, callback)`: Listen for an FS event. +Available events: `add`, `addDir`, `change`, `unlink`, `unlinkDir`, `ready`, +`raw`, `error`. +Additionally `all` is available which gets emitted with the underlying event +name and path for every event other than `ready`, `raw`, and `error`. `raw` is internal, use it carefully. +* `.unwatch(path / paths)`: Stop watching files, directories, or glob patterns. +Takes an array of strings or just one string. +* `.close()`: **async** Removes all listeners from watched files. Asynchronous, returns Promise. Use with `await` to ensure bugs don't happen. +* `.getWatched()`: Returns an object representing all the paths on the file +system being watched by this `FSWatcher` instance. The object's keys are all the +directories (using absolute paths unless the `cwd` option was used), and the +values are arrays of the names of the items contained in each directory. + +## CLI + +If you need a CLI interface for your file watching, check out +[chokidar-cli](https://github.com/open-cli-tools/chokidar-cli), allowing you to +execute a command on each change, or get a stdio stream of change events. + +## Install Troubleshooting + +* `npm WARN optional dep failed, continuing fsevents@n.n.n` + * This message is normal part of how `npm` handles optional dependencies and is + not indicative of a problem. Even if accompanied by other related error messages, + Chokidar should function properly. + +* `TypeError: fsevents is not a constructor` + * Update chokidar by doing `rm -rf node_modules package-lock.json yarn.lock && npm install`, or update your dependency that uses chokidar. + +* Chokidar is producing `ENOSP` error on Linux, like this: + * `bash: cannot set terminal process group (-1): Inappropriate ioctl for device bash: no job control in this shell` + `Error: watch /home/ ENOSPC` + * This means Chokidar ran out of file handles and you'll need to increase their count by executing the following command in Terminal: + `echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p` + +## Changelog + +For more detailed changelog, see [`full_changelog.md`](.github/full_changelog.md). +- **v3.5 (Jan 6, 2021):** Support for ARM Macs with Apple Silicon.

There is ongoing effort to switch this library to streams version 2. Any help is welcome. :) Meanwhile you can explore other libraries that provide streams2 support with more or less compatibility with `combined-stream`. + +- [combined-stream2](https://www.npmjs.com/package/combined-stream2): A drop-in streams2-compatible replacement for the combined-stream module. + +- [multistream](https://www.npmjs.com/package/multistream): A stream that emits multiple other streams one after another. + +## Installation + +``` bash +npm install combined-stream +``` + +## Usage + +Here is a simple example that shows how you can use combined-stream to combine +two files into one: + +``` javascript +var CombinedStream = require('combined-stream'); +var fs = require('fs'); + +var combinedStream = CombinedStream.create(); +combinedStream.append(fs.createReadStream('file1.txt')); +combinedStream.append(fs.createReadStream('file2.txt')); + +combinedStream.pipe(fs.createWriteStream('combined.txt')); +``` + +While the example above works great, it will pause all source streams until +they are needed.

Available options are: + +* `maxDataSize` +* `pauseStreams` + +The effect of those options is described below. + +### combinedStream.pauseStreams = `true` + +Whether to apply back pressure to the underlaying streams. If set to `false`, +the underlaying streams will never be paused. If set to `true`, the +underlaying streams will be paused right after being appended, as well as when +`delayedStream.pipe()` wants to throttle. + +### combinedStream.maxDataSize = `2 * 1024 * 1024` + +The maximum amount of bytes (or characters) to buffer for all source streams. +If this value is exceeded, `combinedStream` emits an `'error'` event. + +### combinedStream.dataSize = `0` + +The amount of bytes (or characters) currently buffered by `combinedStream`. + +### combinedStream.append(stream) + +Appends the given `stream` to the combinedStream object. If `pauseStreams` is +set to `true, this stream will also be paused right away. + +`streams` can also be a function that takes one parameter called `next`. `next` +is a function that must be invoked in order to provide the `next` stream, see +example above. + +Regardless of how the `stream` is appended, combined-stream always attaches an +`'error'` listener to it, so you don't have to do that manually. + +Special case: `stream` can also be a String or Buffer. + +### combinedStream.write(data) + +You should not call this, `combinedStream` takes care of piping the appended +streams into itself for you. + +### combinedStream.resume() + +Causes `combinedStream` to start drain the streams it manages. The function is +idempotent, and also emits a `'resume'` event each time which usually goes to +the stream that is currently being drained. + +### combinedStream.pause(); + +If `combinedStream.pauseStreams` is set to `false`, this does nothing. +Otherwise a `'pause'` event is emitted, this goes to the stream that is +currently being drained, so you can use it to apply back pressure. + +### combinedStream.end(); + +Sets `combinedStream.writable` to false, emits an `'end'` event, and removes +all streams from the queue. + +### combinedStream.destroy(); + +Same as `combinedStream.end()`, except it emits a `'close'` event instead of +`'end'`. + +## License + +combined-stream is licensed under the MIT license. diff --git a/src/node_modules/combined-stream/lib/combined_stream.js b/src/node_modules/combined-stream/lib/combined_stream.js new file mode 100644 index 0000000..125f097 --- /dev/null +++ b/src/node_modules/combined-stream/lib/combined_stream.js @@ -0,0 +1,208 @@ +var util = require('util');

Since the value of a cookie +has a limited character set (and must be a simple string), this function can be used to decode +a previously-encoded cookie value into a JavaScript string or other object. + +The default function is the global `decodeURIComponent`, which will decode any URL-encoded +sequences into their byte representations. + +**note** if an error is thrown from this function, the original, non-decoded cookie value will +be returned as the cookie's value. + +### cookie.serialize(name, value, options) + +Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the +name for the cookie, the `value` argument is the value to set the cookie to, and the `options` +argument is an optional object containing additional serialization options. + +```js +var setCookie = cookie.serialize('foo', 'bar'); +// foo=bar +``` + +#### Options + +`cookie.serialize` accepts these properties in the options object. + +##### domain + +Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6265-5.2.3]. By default, no +domain is set, and most clients will consider the cookie to apply to only the current domain. + +##### encode + +Specifies a function that will be used to encode a cookie's value. Since value of a cookie +has a limited character set (and must be a simple string), this function can be used to encode +a value into a string suited for a cookie's value. + +The default function is the global `encodeURIComponent`, which will encode a JavaScript string +into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range. + +##### expires + +Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6265-5.2.1]. +By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and +will delete it on a condition like exiting a web browser application. + +**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and +`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this, +so if both are set, they should point to the same date and time. + +##### httpOnly + +Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6265-5.2.6]. When truthy, +the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set. + +**note** be careful when setting this to `true`, as compliant clients will not allow client-side +JavaScript to see the cookie in `document.cookie`. + +##### maxAge + +Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6265-5.2.2]. +The given number will be converted to an integer by rounding down. By default, no maximum age is set. + +**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and +`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this, +so if both are set, they should point to the same date and time. + +##### path + +Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6265-5.2.4]. By default, the path +is considered the ["default path"][rfc-6265-5.1.4]. + +##### priority + +Specifies the `string` to be the value for the [`Priority` `Set-Cookie` attribute][rfc-west-cookie-priority-00-4.1]. + + - `'low'` will set the `Priority` attribute to `Low`. + - `'medium'` will set the `Priority` attribute to `Medium`, the default priority when not set. + - `'high'` will set the `Priority` attribute to `High`. + +More information about the different priority levels can be found in +[the specification][rfc-west-cookie-priority-00-4.1]. + +**note** This is an attribute that has not yet been fully standardized, and may change in the future. +This also means many clients may ignore this attribute until they understand it. + +##### sameSite + +Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][rfc-6265bis-09-5.4.7]. + + - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement. + - `false` will not set the `SameSite` attribute. + - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement. + - `'none'` will set the `SameSite` attribute to `None` for an explicit cross-site cookie. + - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement. + +More information about the different enforcement levels can be found in +[the specification][rfc-6265bis-09-5.4.7]. + +**note** This is an attribute that has not yet been fully standardized, and may change in the future. +This also means many clients may ignore this attribute until they understand it. + +##### secure + +Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6265-5.2.5]. When truthy, +the `Secure` attribute is set, otherwise it is not. By default, the `Secure` attribute is not set. + +**note** be careful when setting this to `true`, as compliant clients will not send the cookie back to +the server in the future if the browser does not have an HTTPS connection. + +## Example + +The following example uses this module in conjunction with the Node.js core HTTP server +to prompt a user for their name and display it back on future visits. + +```js +var cookie = require('cookie'); +var escapeHtml = require('escape-html'); +var http = require('http'); +var url = require('url'); + +function onRequest(req, res) { + // Parse the query string + var query = url.parse(req.url, true, true).query; + + if (query && query.name) { + // Set a new cookie with the name + res.setHeader('Set-Cookie', cookie.serialize('name', String(query.name), { + httpOnly: true, + maxAge: 60 * 60 * 24 * 7 // 1 week + })); + + // Redirect back after setting cookie + res.statusCode = 302; + res.setHeader('Location', req.headers.referer || '/'); + res.end(); + return; + } + + // Parse the cookies on the request + var cookies = cookie.parse(req.headers.cookie || ''); + + // Get the visitor name set in the cookie + var name = cookies.name; + + res.setHeader('Content-Type', 'text/html; charset=UTF-8'); + + if (name) { + res.write('

Read on for more on getting the stringified version of the body. + +### Decoding the body + +To decode the body bytes of a parsed data URL, you'll need to use the `charset` parameter of the MIME type, if any. This contains an encoding [label](https://encoding.spec.whatwg.org/#label); there are [various possible labels](https://encoding.spec.whatwg.org/#names-and-labels) for a given encoding. We suggest using the [whatwg-encoding](https://www.npmjs.com/package/whatwg-encoding) package as follows: + +```js +const parseDataURL = require("data-urls"); +const { labelToName, decode } = require("whatwg-encoding"); + +const dataURL = parseDataURL(arbitraryString); + +// If there's no charset parameter, let's just hope it's UTF-8; that seems like a good guess. +const encodingName = labelToName(dataURL.mimeType.parameters.get("charset") || "utf-8"); +const bodyDecoded = decode(dataURL.body, encodingName); +``` + +This is especially important since the default, if no parseable MIME type is given, is "US-ASCII", [aka windows-1252](https://encoding.spec.whatwg.org/#names-and-labels), not UTF-8 like you might asume. So for example given an `arbitraryString` of `"data:,Héllo!"`, the above code snippet will correctly produce a `bodyDecoded` of `"Héllo!"` by using the windows-1252 decoder, whereas if you used a UTF-8 decoder you'd get back `"Héllo!"`. + +### Advanced functionality: parsing from a URL record + +If you are using the [whatwg-url](https://github.com/jsdom/whatwg-url) package, you may already have a "URL record" object on hand, as produced by that package's `parseURL` export. In that case, you can use this package's `fromURLRecord` export to save a bit of work: + +```js +const { parseURL } = require("whatwg-url"); +const dataURLFromURLRecord = require("data-urls").fromURLRecord; + +const urlRecord = parseURL("data:,Hello%2C%20World!"); +const dataURL = dataURLFromURLRecord(urlRecord); +``` + +In practice, we expect this functionality only to be used by consumers like [jsdom](https://www.npmjs.com/package/jsdom), which are using these packages at a very low level. diff --git a/src/node_modules/data-urls/lib/parser.js b/src/node_modules/data-urls/lib/parser.js new file mode 100644 index 0000000..ed9971c --- /dev/null +++ b/src/node_modules/data-urls/lib/parser.js @@ -0,0 +1,69 @@ +"use strict";

This will allow you to toggle the debug output for different parts of your module as well as the module as a whole. + +Example _app.js_: + +```js +var debug = require('debug')('http') + , http = require('http') + , name = 'My App'; + +// fake app + +debug('booting %s', name); + +http.createServer(function(req, res){ + debug(req.method + ' ' + req.url); + res.end('hello\n'); +}).listen(3000, function(){ + debug('listening'); +}); + +// fake worker of some kind + +require('./worker'); +``` + +Example _worker.js_: + +```js +var debug = require('debug')('worker'); + +setInterval(function(){ + debug('doing some work'); +}, 1000); +``` + + The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples: + + ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png) + + ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png) + +#### Windows note + + On Windows the environment variable is set using the `set` command. + + ```cmd + set DEBUG=*,-not_this + ``` + + Note that PowerShell uses different syntax to set environment variables. + + ```cmd + $env:DEBUG = "*,-not_this" + ``` + +Then, run the program to be debugged as usual. + +## Millisecond diff + + When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. + + ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png) + + When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below: + + ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png) + +## Conventions + + If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". + +## Wildcards + + The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. + + You can also exclude specific debuggers by prefixing them with a "-" character. For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:". + +## Environment Variables + + When running through Node.js, you can set a few environment variables that will + change the behavior of the debug logging: + +| Name | Purpose | +|-----------|-------------------------------------------------| +| `DEBUG` | Enables/disables specific debugging namespaces. | +| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | +| `DEBUG_DEPTH` | Object inspection depth. | +| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | + + + __Note:__ The environment variables beginning with `DEBUG_` end up being + converted into an Options object that gets used with `%o`/`%O` formatters. + See the Node.js documentation for + [`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) + for the complete list. + +## Formatters + + + Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters: + +| Formatter | Representation | +|-----------|----------------| +| `%O` | Pretty-print an Object on multiple lines. | +| `%o` | Pretty-print an Object all on a single line. | +| `%s` | String. | +| `%d` | Number (both integer and float). | +| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | +| `%%` | Single percent sign ('%'). This does not consume an argument. | + +### Custom formatters + + You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like: + +```js +const createDebug = require('debug') +createDebug.formatters.h = (v) => { + return v.toString('hex') +} + +// …elsewhere +const debug = createDebug('foo') +debug('this is hex: %h', new Buffer('hello world')) +// foo this is hex: 68656c6c6f20776f726c6421 +0ms +``` + +## Browser support + You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), + or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), + if you don't want to build it yourself. + + Debug's enable state is currently persisted by `localStorage`. + Consider the situation shown below where you have `worker:a` and `worker:b`, + and wish to debug both. You can enable this using `localStorage.debug`: + +```js +localStorage.debug = 'worker:*' +``` + +And then refresh the page. + +```js +a = debug('worker:a'); +b = debug('worker:b'); + +setInterval(function(){ + a('doing some work'); +}, 1000); + +setInterval(function(){ + b('doing some work'); +}, 1200); +``` + +#### Web Inspector Colors + + Colors are also enabled on "Web Inspectors" that understand the `%c` formatting + option. These are WebKit web inspectors, Firefox ([since version + 31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) + and the Firebug plugin for Firefox (any version). + + Colored output looks something like: + + ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png) + + +## Output streams + + By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: + +Example _stdout.js_: + +```js +var debug = require('debug'); +var error = debug('app:error'); + +// by default stderr is used +error('goes to stderr!'); + +var log = debug('app:log'); +// set this namespace to log via console.log +log.log = console.log.bind(console); // don't forget to bind to console! +log('goes to stdout'); +error('still goes to stderr!'); + +// set all output to go via console.info +// overrides all per-namespace log settings +debug.log = console.info.bind(console); +error('now goes to stdout via console.info'); +log('still goes to stdout, but via console.info now'); +``` + + +## Authors + + - TJ Holowaychuk + - Nathan Rajlich + - Andrew Rhyne + +## Backers + +Support us with a monthly donation and help us continue our activities.

Until node implements a catch-all event listener, this is the only way. + +However, delayed-stream still continues to emit all events it captures on the +`source`, regardless of whether you have released the delayed stream yet or +not. + +Upon creation, delayed-stream captures all `source` events and stores them in +an internal event buffer. Once `delayedStream.release()` is called, all +buffered events are emitted on the `delayedStream`, and the event buffer is +cleared. After that, delayed-stream merely acts as a proxy for the underlaying +source. + +### Error handling + +Error events on `source` are buffered / proxied just like any other events. +However, `delayedStream.create` attaches a no-op `'error'` listener to the +`source`. This way you only have to handle errors on the `delayedStream` +object, rather than in two places. + +### Buffer limits + +delayed-stream provides a `maxDataSize` property that can be used to limit +the amount of data being buffered. In order to protect you from bad `source` +streams that don't react to `source.pause()`, this feature is enabled by +default. + +## API + +### DelayedStream.create(source, [options]) + +Returns a new `delayedStream`. Available options are: + +* `pauseStream` +* `maxDataSize` + +The description for those properties can be found below. + +### delayedStream.source + +The `source` stream managed by this object. This is useful if you are +passing your `delayedStream` around, and you still want to access properties +on the `source` object. + +### delayedStream.pauseStream = true + +Whether to pause the underlaying `source` when calling +`DelayedStream.create()`. Modifying this property afterwards has no effect. + +### delayedStream.maxDataSize = 1024 * 1024 + +The amount of data to buffer before emitting an `error`. + +If the underlaying source is emitting `Buffer` objects, the `maxDataSize` +refers to bytes. + +If the underlaying source is emitting JavaScript strings, the size refers to +characters. + +If you know what you are doing, you can set this property to `Infinity` to +disable this feature. You can also modify this property during runtime. + +### delayedStream.dataSize = 0 + +The amount of data buffered so far. + +### delayedStream.readable + +An ECMA5 getter that returns the value of `source.readable`. + +### delayedStream.resume() + +If the `delayedStream` has not been released so far, `delayedStream.release()` +is called. + +In either case, `source.resume()` is called. + +### delayedStream.pause() + +Calls `source.pause()`. + +### delayedStream.pipe(dest) + +Calls `delayedStream.resume()` and then proxies the arguments to `source.pipe`. + +### delayedStream.release() + +Emits and clears all events that have been buffered up so far.

+## Install + +This module is installed directly using `npm`: + +```sh +$ npm install depd +``` + +This module can also be bundled with systems like +[Browserify](http://browserify.org/) or [webpack](https://webpack.github.io/), +though by default this module will alter it's API to no longer display or +track deprecations. + +## API + + + +```js +var deprecate = require('depd')('my-module') +``` + +This library allows you to display deprecation messages to your users. +This library goes above and beyond with deprecation warnings by +introspection of the call stack (but only the bits that it is interested +in). + +Instead of just warning on the first invocation of a deprecated +function and never again, this module will warn on the first invocation +of a deprecated function per unique call site, making it ideal to alert +users of all deprecated uses across the code base, rather than just +whatever happens to execute first. + +The deprecation warnings from this module also include the file and line +information for the call into the module that the deprecated function was +in. + +**NOTE** this library has a similar interface to the `debug` module, and +this module uses the calling file to get the boundary for the call stacks, +so you should always create a new `deprecate` object in each file and not +within some central file. + +### depd(namespace) + +Create a new deprecate function that uses the given namespace name in the +messages and will display the call site prior to the stack entering the +file this function was called from. It is highly suggested you use the +name of your module as the namespace. + +### deprecate(message) + +Call this function from deprecated code to display a deprecation message. +This message will appear once per unique caller site. Caller site is the +first call site in the stack in a different file from the caller of this +function. + +If the message is omitted, a message is generated for you based on the site +of the `deprecate()` call and will display the name of the function called, +similar to the name displayed in a stack trace. + +### deprecate.function(fn, message) + +Call this function to wrap a given function in a deprecation message on any +call to the function. An optional message can be supplied to provide a custom +message. + +### deprecate.property(obj, prop, message) + +Call this function to wrap a given property on object in a deprecation message +on any accessing or setting of the property. An optional message can be supplied +to provide a custom message. + +The method must be called on the object where the property belongs (not +inherited from the prototype). + +If the property is a data descriptor, it will be converted to an accessor +descriptor in order to display the deprecation message. + +### process.on('deprecation', fn) + +This module will allow easy capturing of deprecation errors by emitting the +errors as the type "deprecation" on the global `process`. If there are no +listeners for this type, the errors are written to STDERR as normal, but if +there are any listeners, nothing will be written to STDERR and instead only +emitted. From there, you can write the errors in a different format or to a +logging source. + +The error represents the deprecation and is emitted only once with the same +rules as writing to STDERR. The error has the following properties: + + - `message` - This is the message given by the library + - `name` - This is always `'DeprecationError'` + - `namespace` - This is the namespace the deprecation came from + - `stack` - This is the stack of the call to the deprecated thing + +Example `error.stack` output: + +``` +DeprecationError: my-cool-module deprecated oldfunction + at Object. ([eval]-wrapper:6:22) + at Module._compile (module.js:456:26) + at evalScript (node.js:532:25) + at startup (node.js:80:7) + at node.js:902:3 +``` + +### process.env.NO_DEPRECATION + +As a user of modules that are deprecated, the environment variable `NO_DEPRECATION` +is provided as a quick solution to silencing deprecation warnings from being +output. The format of this is similar to that of `DEBUG`: + +```sh +$ NO_DEPRECATION=my-module,othermod node app.js +``` + +This will suppress deprecations from being output for "my-module" and "othermod". +The value is a list of comma-separated namespaces. To suppress every warning +across all namespaces, use the value `*` for a namespace. + +Providing the argument `--no-deprecation` to the `node` executable will suppress +all deprecations (only available in Node.js 0.8 or higher). + +**NOTE** This will not suppress the deperecations given to any "deprecation" +event listeners, just the output to STDERR. + +### process.env.TRACE_DEPRECATION + +As a user of modules that are deprecated, the environment variable `TRACE_DEPRECATION` +is provided as a solution to getting more detailed location information in deprecation +warnings by including the entire stack trace. The format of this is the same as +`NO_DEPRECATION`: + +```sh +$ TRACE_DEPRECATION=my-module,othermod node app.js +``` + +This will include stack traces for deprecations being output for "my-module" and +"othermod". The value is a list of comma-separated namespaces. To trace every +warning across all namespaces, use the value `*` for a namespace. + +Providing the argument `--trace-deprecation` to the `node` executable will trace +all deprecations (only available in Node.js 0.8 or higher). + +**NOTE** This will not trace the deperecations silenced by `NO_DEPRECATION`. + +## Display + +![message](files/message.png) + +When a user calls a function in your library that you mark deprecated, they +will see the following written to STDERR (in the given colors, similar colors +and layout to the `debug` module): + +``` +bright cyan bright yellow +| | reset cyan +| | | | +▼ ▼ ▼ ▼ +my-cool-module deprecated oldfunction [eval]-wrapper:6:22 +▲ ▲ ▲ ▲ +| | | | +namespace | | location of mycoolmod.oldfunction() call + | deprecation message + the word "deprecated" +``` + +If the user redirects their STDERR to a file or somewhere that does not support +colors, they see (similar layout to the `debug` module): + +``` +Sun, 15 Jun 2014 05:21:37 GMT my-cool-module deprecated oldfunction at [eval]-wrapper:6:22 +▲ ▲ ▲ ▲ ▲ +| | | | | +timestamp of message namespace | | location of mycoolmod.oldfunction() call + | deprecation message + the word "deprecated" +``` + +## Examples + +### Deprecating all calls to a function + +This will display a deprecated message about "oldfunction" being deprecated +from "my-module" on STDERR. + +```js +var deprecate = require('depd')('my-cool-module') + +// message automatically derived from function name +// Object.oldfunction +exports.oldfunction = deprecate.function(function oldfunction () { + // all calls to function are deprecated +}) + +// specific message +exports.oldfunction = deprecate.function(function () { + // all calls to function are deprecated +}, 'oldfunction') +``` + +### Conditionally deprecating a function call + +This will display a deprecated message about "weirdfunction" being deprecated +from "my-module" on STDERR when called with less than 2 arguments. + +```js +var deprecate = require('depd')('my-cool-module') + +exports.weirdfunction = function () { + if (arguments.length < 2) { + // calls with 0 or 1 args are deprecated + deprecate('weirdfunction args < 2') + } +} +``` + +When calling `deprecate` as a function, the warning is counted per call site +within your own module, so you can display different deprecations depending +on different situations and the users will still get all the warnings: + +```js +var deprecate = require('depd')('my-cool-module') + +exports.weirdfunction = function () { + if (arguments.length < 2) { + // calls with 0 or 1 args are deprecated + deprecate('weirdfunction args < 2') + } else if (typeof arguments[0] !== 'string') { + // calls with non-string first argument are deprecated + deprecate('weirdfunction non-string first arg') + } +} +``` + +### Deprecating property access + +This will display a deprecated message about "oldprop" being deprecated +from "my-module" on STDERR when accessed. A deprecation will be displayed +when setting the value and when getting the value. + +```js +var deprecate = require('depd')('my-cool-module') + +exports.oldprop = 'something' + +// message automatically derives from property name +deprecate.property(exports, 'oldprop') + +// explicit message +deprecate.property(exports, 'oldprop', 'oldprop >= 0.10') +``` + +## License + +[MIT](LICENSE)

The callback is used to handle errors and continue once the length has been calculated +```javascript +this.getLength(function(err, length) { + if (err) { + this._error(err); + return; + } + + // add content length + request.setHeader('Content-Length', length); + + ... +}.bind(this)); +``` + +#### _Boolean_ hasKnownLength() +Checks if the length of added values is known. + +#### _Request_ submit( _params_, **function** _callback_ ) +Submit the form to a web application. +```javascript +var form = new FormData(); +form.append( 'my_string', 'Hello World' ); + +form.submit( 'http://example.com/', function(err, res) { + // res – response object (http.IncomingMessage) // + res.resume(); +} ); +``` + +#### _String_ toString() +Returns the form data as a string. Don't use this if you are sending files or buffers, use `getBuffer()` instead. + +### Integration with other libraries + +#### Request + +Form submission using [request](https://github.com/request/request): + +```javascript +var formData = { + my_field: 'my_value', + my_file: fs.createReadStream(__dirname + '/unicycle.jpg'), +}; + +request.post({url:'http://service.com/upload', formData: formData}, function(err, httpResponse, body) { + if (err) { + return console.error('upload failed:', err); + } + console.log('Upload successful! Server responded with:', body); +}); +``` + +For more details see [request readme](https://github.com/request/request#multipartform-data-multipart-form-uploads). + +#### node-fetch + +You can also submit a form using [node-fetch](https://github.com/bitinn/node-fetch): + +```javascript +var form = new FormData(); + +form.append('a', 1); + +fetch('http://example.com', { method: 'POST', body: form }) + .then(function(res) { + return res.json(); + }).then(function(json) { + console.log(json); + }); +``` + +#### axios + +In Node.js you can post a file using [axios](https://github.com/axios/axios): +```javascript +const form = new FormData(); +const stream = fs.createReadStream(PATH_TO_FILE); + +form.append('image', stream); + +// In Node.js environment you need to set boundary in the header field 'Content-Type' by calling method `getHeaders` +const formHeaders = form.getHeaders(); + +axios.post('http://example.com', form, { + headers: { + ...formHeaders, + }, +}) +.then(response => response) +.catch(error => error) +``` + +## Notes + +- ```getLengthSync()``` method DOESN'T calculate length for streams, use ```knownLength``` options as workaround. +- ```getLength(cb)``` will send an error as first parameter of callback if stream length cannot be calculated (e.g. send in custom streams w/o using ```knownLength```). +- ```submit``` will not add `content-length` if form length is unknown or not calculable. +- Starting version `2.x` FormData has dropped support for `node@0.10.x`. +- Starting version `3.x` FormData has dropped support for `node@4.x`. + +## License + +Form-Data is released under the [MIT](License) license. diff --git a/src/node_modules/form-data/index.d.ts b/src/node_modules/form-data/index.d.ts new file mode 100644 index 0000000..295e9e9 --- /dev/null +++ b/src/node_modules/form-data/index.d.ts @@ -0,0 +1,62 @@ +// Definitions by: Carlos Ballesteros Velasco +// Leon Yu +// BendingBender +// Maple Miao + +/// +import * as stream from 'stream'; +import * as http from 'http'; + +export = FormData; + +// Extracted because @types/node doesn't export interfaces. +interface ReadableOptions { + highWaterMark?: number; + encoding?: string; + objectMode?: boolean; + read?(this: stream.Readable, size: number): void; + destroy?(this: stream.Readable, error: Error | null, callback: (error: Error | null) => void): void; + autoDestroy?: boolean; +} + +interface Options extends ReadableOptions { + writable?: boolean; + readable?: boolean; + dataSize?: number; + maxDataSize?: number; + pauseStreams?: boolean; +} + +declare class FormData extends stream.Readable { + constructor(options?: Options); + append(key: string, value: any, options?: FormData.AppendOptions | string): void; + getHeaders(userHeaders?: FormData.Headers): FormData.Headers; + submit( + params: string | FormData.SubmitOptions, + callback?: (error: Error | null, response: http.IncomingMessage) => void + ): http.ClientRequest; + getBuffer(): Buffer; + setBoundary(boundary: string): void; + getBoundary(): string; + getLength(callback: (err: Error | null, length: number) => void): void; + getLengthSync(): number; + hasKnownLength(): boolean; +} + +declare namespace FormData { + interface Headers { + [key: string]: any; + } + + interface AppendOptions { + header?: string | Headers; + knownLength?: number; + filename?: string; + filepath?: string; + contentType?: string; + } + + interface SubmitOptions extends http.RequestOptions { + protocol?: 'https:' | 'http:'; + } +} diff --git a/src/node_modules/form-data/lib/browser.js b/src/node_modules/form-data/lib/browser.js new file mode 100644 index 0000000..09e7c70 --- /dev/null +++ b/src/node_modules/form-data/lib/browser.js @@ -0,0 +1,2 @@ +/* eslint-env browser */ +module.exports = typeof self == 'object' ?

The module +[jumanji](https://www.npmjs.com/package/jumanji) can be used in +an Express application to work-around this issue and also provides +links to further reading on this Safari bug. + +## Example + +### API usage + + + +```js +var reqHeaders = { 'if-none-match': '"foo"' } +var resHeaders = { 'etag': '"bar"' } +fresh(reqHeaders, resHeaders) +// => false + +var reqHeaders = { 'if-none-match': '"foo"' } +var resHeaders = { 'etag': '"foo"' } +fresh(reqHeaders, resHeaders) +// => true +``` + +### Using with Node.js http server + +```js +var fresh = require('fresh') +var http = require('http') + +var server = http.createServer(function (req, res) { + // perform server logic + // ... including adding ETag / Last-Modified response headers + + if (isFresh(req, res)) { + // client has a fresh copy of resource + res.statusCode = 304 + res.end() + return + } + + // send the resource + res.statusCode = 200 + res.end('hello, world!') +}) + +function isFresh (req, res) { +

If a path with backslashes +is provided anyway, for simple cases, glob-parent will replace the path +separator for you and return the non-glob parent path (now with +forward-slashes, which are still valid as Windows path separators). + +This cannot be used in conjunction with escape characters. + +```js +// BAD +globParent('C:\\Program Files \\(x86\\)\\*.ext') // 'C:/Program Files /(x86/)' + +// GOOD +globParent('C:/Program Files\\(x86\\)/*.ext') // 'C:/Program Files (x86)' +``` + +If you are using escape characters for a pattern without path parts (i.e. +relative to `cwd`), prefix with `./` to avoid confusing glob-parent. + +```js +// BAD +globParent('foo \\[bar]') // 'foo ' +globParent('foo \\[bar]*') // 'foo ' + +// GOOD +globParent('./foo \\[bar]') // 'foo [bar]' +globParent('./foo \\[bar]*') // '.' +``` + +## License + +ISC + +[expand-braces]: https://github.com/jonschlinkert/expand-braces +[expand-brackets]: https://github.com/jonschlinkert/expand-brackets + +[downloads-image]: https://img.shields.io/npm/dm/glob-parent.svg +[npm-url]: https://www.npmjs.com/package/glob-parent +[npm-image]: https://img.shields.io/npm/v/glob-parent.svg + +[azure-pipelines-url]: https://dev.azure.com/gulpjs/gulp/_build/latest?definitionId=2&branchName=master +[azure-pipelines-image]: https://dev.azure.com/gulpjs/gulp/_apis/build/status/glob-parent?branchName=master + +[travis-url]: https://travis-ci.org/gulpjs/glob-parent +[travis-image]: https://img.shields.io/travis/gulpjs/glob-parent.svg?label=travis-ci + +[appveyor-url]: https://ci.appveyor.com/project/gulpjs/glob-parent +[appveyor-image]: https://img.shields.io/appveyor/ci/gulpjs/glob-parent.svg?label=appveyor + +[coveralls-url]: https://coveralls.io/r/gulpjs/glob-parent +[coveralls-image]: https://img.shields.io/coveralls/gulpjs/glob-parent/master.svg + +[gitter-url]: https://gitter.im/gulpjs/gulp +[gitter-image]: https://badges.gitter.im/gulpjs/gulp.svg diff --git a/src/node_modules/glob-parent/index.js b/src/node_modules/glob-parent/index.js new file mode 100644 index 0000000..09e257e --- /dev/null +++ b/src/node_modules/glob-parent/index.js @@ -0,0 +1,42 @@ +'use strict';

You also _should_ install +the [`supports-color`](https://npmjs.org/supports-color) module alongside debug, +otherwise debug will only use a small handful of basic colors. + + + +#### Web Browser + +Colors are also enabled on "Web Inspectors" that understand the `%c` formatting +option. These are WebKit web inspectors, Firefox ([since version +31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) +and the Firebug plugin for Firefox (any version). + + + + +## Millisecond diff + +When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. + + + +When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below: + + + + +## Conventions + +If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output. + +## Wildcards + +The `*` character may be used as a wildcard. Suppose for example your library has +debuggers named "connect:bodyParser", "connect:compress", "connect:session", +instead of listing all three with +`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do +`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. + +You can also exclude specific debuggers by prefixing them with a "-" character. +For example, `DEBUG=*,-connect:*` would include all debuggers except those +starting with "connect:". + +## Environment Variables + +When running through Node.js, you can set a few environment variables that will +change the behavior of the debug logging: + +| Name | Purpose | +|-----------|-------------------------------------------------| +| `DEBUG` | Enables/disables specific debugging namespaces. | +| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). | +| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | +| `DEBUG_DEPTH` | Object inspection depth. | +| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | + + +__Note:__ The environment variables beginning with `DEBUG_` end up being +converted into an Options object that gets used with `%o`/`%O` formatters. +See the Node.js documentation for +[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) +for the complete list. + +## Formatters + +Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. +Below are the officially supported formatters: + +| Formatter | Representation | +|-----------|----------------| +| `%O` | Pretty-print an Object on multiple lines. | +| `%o` | Pretty-print an Object all on a single line. | +| `%s` | String. | +| `%d` | Number (both integer and float). | +| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | +| `%%` | Single percent sign ('%'). This does not consume an argument. | + + +### Custom formatters + +You can add custom formatters by extending the `debug.formatters` object. +For example, if you wanted to add support for rendering a Buffer as hex with +`%h`, you could do something like: + +```js +const createDebug = require('debug') +createDebug.formatters.h = (v) => { + return v.toString('hex') +} + +// …elsewhere +const debug = createDebug('foo') +debug('this is hex: %h', new Buffer('hello world')) +// foo this is hex: 68656c6c6f20776f726c6421 +0ms +``` + + +## Browser Support + +You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), +or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), +if you don't want to build it yourself. + +Debug's enable state is currently persisted by `localStorage`. +Consider the situation shown below where you have `worker:a` and `worker:b`, +and wish to debug both. You can enable this using `localStorage.debug`: + +```js +localStorage.debug = 'worker:*' +``` + +And then refresh the page. + +```js +a = debug('worker:a'); +b = debug('worker:b'); + +setInterval(function(){ + a('doing some work'); +}, 1000); + +setInterval(function(){ + b('doing some work'); +}, 1200); +``` + +In Chromium-based web browsers (e.g. Brave, Chrome, and Electron), the JavaScript console will—by default—only show messages logged by `debug` if the "Verbose" log level is _enabled_. + + + +## Output streams + + By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: + +Example [_stdout.js_](./examples/node/stdout.js): + +```js +var debug = require('debug'); +var error = debug('app:error'); + +// by default stderr is used +error('goes to stderr!'); + +var log = debug('app:log'); +// set this namespace to log via console.log +log.log = console.log.bind(console); // don't forget to bind to console! +log('goes to stdout'); +error('still goes to stderr!'); + +// set all output to go via console.info +// overrides all per-namespace log settings +debug.log = console.info.bind(console); +error('now goes to stdout via console.info'); +log('still goes to stdout, but via console.info now'); +``` + +## Extend +You can simply extend debugger +```js +const log = require('debug')('auth'); + +//creates new debug instance with extended namespace +const logSign = log.extend('sign'); +const logLogin = log.extend('login'); + +log('hello'); // auth hello +logSign('hello'); //auth:sign hello +logLogin('hello'); //auth:login hello +``` + +## Set dynamically + +You can also enable debug dynamically by calling the `enable()` method : + +```js +let debug = require('debug'); + +console.log(1, debug.enabled('test')); + +debug.enable('test'); +console.log(2, debug.enabled('test')); + +debug.disable(); +console.log(3, debug.enabled('test')); + +``` + +print : +``` +1 false +2 true +3 false +``` + +Usage : +`enable(namespaces)` +`namespaces` can include modes separated by a colon and wildcards. + +Note that calling `enable()` completely overrides previously set DEBUG variable : + +``` +$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))' +=> false +``` + +`disable()` + +Will disable all namespaces. The functions returns the namespaces currently +enabled (and skipped). This can be useful if you want to disable debugging +temporarily without knowing what was enabled to begin with. + +For example: + +```js +let debug = require('debug'); +debug.enable('foo:*,-foo:bar'); +let namespaces = debug.disable(); +debug.enable(namespaces); +``` + +Note: There is no guarantee that the string will be identical to the initial +enable string, but semantically they will be identical. + +## Checking whether a debug target is enabled + +After you've created a debug instance, you can determine whether or not it is +enabled by checking the `enabled` property: + +```javascript +const debug = require('debug')('http'); + +if (debug.enabled) { + // do stuff... +} +``` + +You can also manually toggle this property to force the debug instance to be +enabled or disabled. + +## Usage in child processes + +Due to the way `debug` detects if the output is a TTY or not, colors are not shown in child processes when `stderr` is piped. A solution is to pass the `DEBUG_COLORS=1` environment variable to the child process. +For example: + +```javascript +worker = fork(WORKER_WRAP_PATH, [workerPath], { + stdio: [ + /* stdin: */ 0, + /* stdout: */ 'pipe', + /* stderr: */ 'pipe', + 'ipc', + ], + env: Object.assign({}, process.env, { + DEBUG_COLORS: 1 // without this settings, colors won't be shown + }), +}); + +worker.stderr.pipe(process.stderr, { end: false }); +``` + + +## Authors + + - TJ Holowaychuk + - Nathan Rajlich + - Andrew Rhyne + - Josh Junon + +## Backers + +Support us with a monthly donation and help us continue our activities.

Works in Node.js and web browsers. + +## Installation + +```bash +$ npm install debug +``` + +## Usage + +`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole. + +Example [_app.js_](./examples/node/app.js): + +```js +var debug = require('debug')('http') + , http = require('http') + , name = 'My App'; + +// fake app + +debug('booting %o', name); + +http.createServer(function(req, res){ + debug(req.method + ' ' + req.url); + res.end('hello\n'); +}).listen(3000, function(){ + debug('listening'); +}); + +// fake worker of some kind + +require('./worker'); +``` + +Example [_worker.js_](./examples/node/worker.js): + +```js +var a = require('debug')('worker:a') + , b = require('debug')('worker:b'); + +function work() { + a('doing lots of uninteresting work'); + setTimeout(work, Math.random() * 1000); +} + +work(); + +function workb() { + b('doing some work'); + setTimeout(workb, Math.random() * 2000); +} + +workb(); +``` + +The `DEBUG` environment variable is then used to enable these based on space or +comma-delimited names. + +Here are some examples: + +screen shot 2017-08-08 at 12 53 04 pm +screen shot 2017-08-08 at 12 53 38 pm +screen shot 2017-08-08 at 12 53 25 pm + +#### Windows command prompt notes + +##### CMD + +On Windows the environment variable is set using the `set` command. + +```cmd +set DEBUG=*,-not_this +``` + +Example: + +```cmd +set DEBUG=* & node app.js +``` + +##### PowerShell (VS Code default) + +PowerShell uses different syntax to set environment variables. + +```cmd +$env:DEBUG = "*,-not_this" +``` + +Example: + +```cmd +$env:DEBUG='app';node app.js +``` + +Then, run the program to be debugged as usual. + +npm script example: +```js + "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js", +``` + +## Namespace Colors + +Every debug instance has a color generated for it based on its namespace name. +This helps when visually parsing the debug output to identify which debug instance +a debug line belongs to. + +#### Node.js + +In Node.js, colors are enabled when stderr is a TTY. You also _should_ install +the [`supports-color`](https://npmjs.org/supports-color) module alongside debug, +otherwise debug will only use a small handful of basic colors. + + + +#### Web Browser + +Colors are also enabled on "Web Inspectors" that understand the `%c` formatting +option. These are WebKit web inspectors, Firefox ([since version +31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) +and the Firebug plugin for Firefox (any version). + + + + +## Millisecond diff + +When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. + + + +When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below: + + + + +## Conventions + +If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output. + +## Wildcards + +The `*` character may be used as a wildcard. Suppose for example your library has +debuggers named "connect:bodyParser", "connect:compress", "connect:session", +instead of listing all three with +`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do +`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. + +You can also exclude specific debuggers by prefixing them with a "-" character. +For example, `DEBUG=*,-connect:*` would include all debuggers except those +starting with "connect:". + +## Environment Variables + +When running through Node.js, you can set a few environment variables that will +change the behavior of the debug logging: + +| Name | Purpose | +|-----------|-------------------------------------------------| +| `DEBUG` | Enables/disables specific debugging namespaces. | +| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). | +| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | +| `DEBUG_DEPTH` | Object inspection depth. | +| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | + + +__Note:__ The environment variables beginning with `DEBUG_` end up being +converted into an Options object that gets used with `%o`/`%O` formatters. +See the Node.js documentation for +[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) +for the complete list. + +## Formatters + +Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. +Below are the officially supported formatters: + +| Formatter | Representation | +|-----------|----------------| +| `%O` | Pretty-print an Object on multiple lines. | +| `%o` | Pretty-print an Object all on a single line. | +| `%s` | String. | +| `%d` | Number (both integer and float). | +| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | +| `%%` | Single percent sign ('%'). This does not consume an argument. | + + +### Custom formatters + +You can add custom formatters by extending the `debug.formatters` object. +For example, if you wanted to add support for rendering a Buffer as hex with +`%h`, you could do something like: + +```js +const createDebug = require('debug') +createDebug.formatters.h = (v) => { + return v.toString('hex') +} + +// …elsewhere +const debug = createDebug('foo') +debug('this is hex: %h', new Buffer('hello world')) +// foo this is hex: 68656c6c6f20776f726c6421 +0ms +``` + + +## Browser Support + +You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), +or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), +if you don't want to build it yourself. + +Debug's enable state is currently persisted by `localStorage`. +Consider the situation shown below where you have `worker:a` and `worker:b`, +and wish to debug both. You can enable this using `localStorage.debug`: + +```js +localStorage.debug = 'worker:*' +``` + +And then refresh the page. + +```js +a = debug('worker:a'); +b = debug('worker:b'); + +setInterval(function(){ + a('doing some work'); +}, 1000); + +setInterval(function(){ + b('doing some work'); +}, 1200); +``` + +In Chromium-based web browsers (e.g. Brave, Chrome, and Electron), the JavaScript console will—by default—only show messages logged by `debug` if the "Verbose" log level is _enabled_. + + + +## Output streams + + By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: + +Example [_stdout.js_](./examples/node/stdout.js): + +```js +var debug = require('debug'); +var error = debug('app:error'); + +// by default stderr is used +error('goes to stderr!'); + +var log = debug('app:log'); +// set this namespace to log via console.log +log.log = console.log.bind(console); // don't forget to bind to console! +log('goes to stdout'); +error('still goes to stderr!'); + +// set all output to go via console.info +// overrides all per-namespace log settings +debug.log = console.info.bind(console); +error('now goes to stdout via console.info'); +log('still goes to stdout, but via console.info now'); +``` + +## Extend +You can simply extend debugger +```js +const log = require('debug')('auth'); + +//creates new debug instance with extended namespace +const logSign = log.extend('sign'); +const logLogin = log.extend('login'); + +log('hello'); // auth hello +logSign('hello'); //auth:sign hello +logLogin('hello'); //auth:login hello +``` + +## Set dynamically + +You can also enable debug dynamically by calling the `enable()` method : + +```js +let debug = require('debug'); + +console.log(1, debug.enabled('test')); + +debug.enable('test'); +console.log(2, debug.enabled('test')); + +debug.disable(); +console.log(3, debug.enabled('test')); + +``` + +print : +``` +1 false +2 true +3 false +``` + +Usage : +`enable(namespaces)` +`namespaces` can include modes separated by a colon and wildcards. + +Note that calling `enable()` completely overrides previously set DEBUG variable : + +``` +$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))' +=> false +``` + +`disable()` + +Will disable all namespaces. The functions returns the namespaces currently +enabled (and skipped). This can be useful if you want to disable debugging +temporarily without knowing what was enabled to begin with. + +For example: + +```js +let debug = require('debug'); +debug.enable('foo:*,-foo:bar'); +let namespaces = debug.disable(); +debug.enable(namespaces); +``` + +Note: There is no guarantee that the string will be identical to the initial +enable string, but semantically they will be identical. + +## Checking whether a debug target is enabled + +After you've created a debug instance, you can determine whether or not it is +enabled by checking the `enabled` property: + +```javascript +const debug = require('debug')('http'); + +if (debug.enabled) { + // do stuff... +} +``` + +You can also manually toggle this property to force the debug instance to be +enabled or disabled. + +## Usage in child processes + +Due to the way `debug` detects if the output is a TTY or not, colors are not shown in child processes when `stderr` is piped. A solution is to pass the `DEBUG_COLORS=1` environment variable to the child process. +For example: + +```javascript +worker = fork(WORKER_WRAP_PATH, [workerPath], { + stdio: [ + /* stdin: */ 0, + /* stdout: */ 'pipe', + /* stderr: */ 'pipe', + 'ipc', + ], + env: Object.assign({}, process.env, { + DEBUG_COLORS: 1 // without this settings, colors won't be shown + }), +}); + +worker.stderr.pipe(process.stderr, { end: false }); +``` + + +## Authors + + - TJ Holowaychuk + - Nathan Rajlich + - Andrew Rhyne + - Josh Junon + +## Backers + +Support us with a monthly donation and help us continue our activities.

First two are straightforward, but UTF-16 is trying to be +smart about endianness in the following ways: + * Decoding: uses BOM and 'spaces heuristic' to determine input endianness. Default is UTF-16LE, but can be + overridden with `defaultEncoding: 'utf-16be'` option. Strips BOM unless `stripBOM: false`. + * Encoding: uses UTF-16LE and writes BOM by default.

It is useful when you have a Node.js instance listening +on an IPv6 socket, and the `net.ivp6.bindv6only` sysctl parameter (or its +equivalent on non-Linux OS) is set to 0. In this case, you can accept IPv4 +connections on your IPv6-only socket, but the remote address will be mangled. +Use `ipaddr.process` method to automatically demangle it. + +### Object representation + +Parsing methods return an object which descends from `ipaddr.IPv6` or +`ipaddr.IPv4`. These objects share some properties, but most of them differ. + +#### Shared properties + +One can determine the type of address by calling `addr.kind()`. It will return +either `"ipv6"` or `"ipv4"`. + +An address can be converted back to its string representation with `addr.toString()`. +Note that this method: + * does not return the original string used to create the object (in fact, there is + no way of getting that string) + * returns a compact representation (when it is applicable) + +A `match(range, bits)` method can be used to check if the address falls into a +certain CIDR range. +Note that an address can be (obviously) matched only against an address of the same type. + +For example: + +```js +var addr = ipaddr.parse("2001:db8:1234::1"); +var range = ipaddr.parse("2001:db8::"); + +addr.match(range, 32); // => true +``` + +Alternatively, `match` can also be called as `match([range, bits])`. In this way, +it can be used together with the `parseCIDR(string)` method, which parses an IP +address together with a CIDR range. + +For example: + +```js +var addr = ipaddr.parse("2001:db8:1234::1"); + +addr.match(ipaddr.parseCIDR("2001:db8::/32")); // => true +``` + +A `range()` method returns one of predefined names for several special ranges defined +by IP protocols. The exact names (and their respective CIDR ranges) can be looked up +in the source: [IPv6 ranges] and [IPv4 ranges]. Some common ones include `"unicast"` +(the default one) and `"reserved"`. + +You can match against your own range list by using +`ipaddr.subnetMatch(address, rangeList, defaultName)` method. It can work with a mix of IPv6 or IPv4 addresses, and accepts a name-to-subnet map as the range list. For example: + +```js +var rangeList = { + documentationOnly: [ ipaddr.parse('2001:db8::'), 32 ], + tunnelProviders: [ + [ ipaddr.parse('2001:470::'), 32 ], // he.net + [ ipaddr.parse('2001:5c0::'), 32 ] // freenet6 + ] +}; +ipaddr.subnetMatch(ipaddr.parse('2001:470:8:66::1'), rangeList, 'unknown'); // => "tunnelProviders" +``` + +The addresses can be converted to their byte representation with `toByteArray()`. +(Actually, JavaScript mostly does not know about byte buffers. They are emulated with +arrays of numbers, each in range of 0..255.) + +```js +var bytes = ipaddr.parse('2a00:1450:8007::68').toByteArray(); // ipv6.google.com +bytes // => [42, 0x00, 0x14, 0x50, 0x80, 0x07, 0x00, , 0x00, 0x68 ] +``` + +The `ipaddr.IPv4` and `ipaddr.IPv6` objects have some methods defined, too. All of them +have the same interface for both protocols, and are similar to global methods. + +`ipaddr.IPvX.isValid(string)` can be used to check if the string is a valid address +for particular protocol, and `ipaddr.IPvX.parse(string)` is the error-throwing parser. + +`ipaddr.IPvX.isValid(string)` uses the same format for parsing as the POSIX `inet_ntoa` function, which accepts unusual formats like `0xc0.168.1.1` or `0x10000000`. The function `ipaddr.IPv4.isValidFourPartDecimal(string)` validates the IPv4 address and also ensures that it is written in four-part decimal format. + +[IPv6 ranges]: https://github.com/whitequark/ipaddr.js/blob/master/src/ipaddr.coffee#L186 +[IPv4 ranges]: https://github.com/whitequark/ipaddr.js/blob/master/src/ipaddr.coffee#L71 + +#### IPv6 properties + +Sometimes you will want to convert IPv6 not to a compact string representation (with +the `::` substitution); the `toNormalizedString()` method will return an address where +all zeroes are explicit. + +For example: + +```js +var addr = ipaddr.parse("2001:0db8::0001"); +addr.toString(); // => "2001:db8::1" +addr.toNormalizedString(); // => "2001:db8:0:0:0:0:0:1" +``` + +The `isIPv4MappedAddress()` method will return `true` if this address is an IPv4-mapped +one, and `toIPv4Address()` will return an IPv4 object address. + +To access the underlying binary representation of the address, use `addr.parts`. + +```js +var addr = ipaddr.parse("2001:db8:10::1234:DEAD"); +addr.parts // => [0x2001, 0xdb8, 0x10, 0, 0, 0, 0x1234, 0xdead] +``` + +A IPv6 zone index can be accessed via `addr.zoneId`: + +```js +var addr = ipaddr.parse("2001:db8::%eth0"); +addr.zoneId // => 'eth0' +``` + +#### IPv4 properties + +`toIPv4MappedAddress()` will return a corresponding IPv4-mapped IPv6 address. + +To access the underlying representation of the address, use `addr.octets`. + +```js +var addr = ipaddr.parse("192.168.1.1"); +addr.octets // => [192, 168, 1, 1] +``` + +`prefixLengthFromSubnetMask()` will return a CIDR prefix length for a valid IPv4 netmask or +null if the netmask is not valid. + +```js +ipaddr.IPv4.parse('255.255.255.240').prefixLengthFromSubnetMask() == 28 +ipaddr.IPv4.parse('255.192.164.0').prefixLengthFromSubnetMask() == null +``` + +`subnetMaskFromPrefixLength()` will return an IPv4 netmask for a valid CIDR prefix length. + +```js +ipaddr.IPv4.subnetMaskFromPrefixLength(24) == "255.255.255.0" +ipaddr.IPv4.subnetMaskFromPrefixLength(29) == "255.255.255.248" +``` + +`broadcastAddressFromCIDR()` will return the broadcast address for a given IPv4 interface and netmask in CIDR notation. +```js +ipaddr.IPv4.broadcastAddressFromCIDR("172.0.0.1/24") == "172.0.0.255" +``` +`networkAddressFromCIDR()` will return the network address for a given IPv4 interface and netmask in CIDR notation. +```js +ipaddr.IPv4.networkAddressFromCIDR("172.0.0.1/24") == "172.0.0.0" +``` + +#### Conversion + +IPv4 and IPv6 can be converted bidirectionally to and from network byte order (MSB) byte arrays. + +The `fromByteArray()` method will take an array and create an appropriate IPv4 or IPv6 object +if the input satisfies the requirements.

+ jsdom +

+ +jsdom is a pure-JavaScript implementation of many web standards, notably the WHATWG [DOM](https://dom.spec.whatwg.org/) and [HTML](https://html.spec.whatwg.org/multipage/) Standards, for use with Node.js. In general, the goal of the project is to emulate enough of a subset of a web browser to be useful for testing and scraping real-world web applications. + +The latest versions of jsdom require Node.js v14 or newer. (Versions of jsdom below v20 still work with previous Node.js versions, but are unsupported.) + +## Basic usage + +```js +const jsdom = require("jsdom"); +const { JSDOM } = jsdom; +``` + +To use jsdom, you will primarily use the `JSDOM` constructor, which is a named export of the jsdom main module. Pass the constructor a string. You will get back a `JSDOM` object, which has a number of useful properties, notably `window`: + +```js +const dom = new JSDOM(`

Hello world

`); +console.log(dom.window.document.querySelector("p").textContent); // "Hello world" +``` + +(Note that jsdom will parse the HTML you pass it just like a browser does, including implied ``, ``, and `` tags.) + +The resulting object is an instance of the `JSDOM` class, which contains a number of useful properties and methods besides `window`. In general, it can be used to act on the jsdom from the "outside," doing things that are not possible with the normal DOM APIs. For simple cases, where you don't need any of this functionality, we recommend a coding pattern like + +```js +const { window } = new JSDOM(`...`); +// or even +const { document } = (new JSDOM(`...`)).window; +``` + +Full documentation on everything you can do with the `JSDOM` class is below, in the section "`JSDOM` Object API". + +## Customizing jsdom + +The `JSDOM` constructor accepts a second parameter which can be used to customize your jsdom in the following ways. + +### Simple options + +```js +const dom = new JSDOM(``, { + url: "https://example.org/", + referrer: "https://example.com/", + contentType: "text/html", + includeNodeLocations: true, + storageQuota: 10000000 +}); +``` + +- `url` sets the value returned by `window.location`, `document.URL`, and `document.documentURI`, and affects things like resolution of relative URLs within the document and the same-origin restrictions and referrer used while fetching subresources. It defaults to `"about:blank"`. +- `referrer` just affects the value read from `document.referrer`. It defaults to no referrer (which reflects as the empty string). +- `contentType` affects the value read from `document.contentType`, as well as how the document is parsed: as HTML or as XML. Values that are not a [HTML mime type](https://mimesniff.spec.whatwg.org/#html-mime-type) or an [XML mime type](https://mimesniff.spec.whatwg.org/#xml-mime-type) will throw. It defaults to `"text/html"`. If a `charset` parameter is present, it can affect [binary data processing](#encoding-sniffing). +- `includeNodeLocations` preserves the location info produced by the HTML parser, allowing you to retrieve it with the `nodeLocation()` method (described below). It also ensures that line numbers reported in exception stack traces for code running inside ` +`); + +// The script will not be executed, by default: +dom.window.document.body.children.length === 1; +``` + +To enable executing scripts inside the page, you can use the `runScripts: "dangerously"` option: + +```js +const dom = new JSDOM(` + +`, { runScripts: "dangerously" }); + +// The script will be executed and modify the DOM: +dom.window.document.body.children.length === 2; +``` + +Again we emphasize to only use this when feeding jsdom code you know is safe. If you use it on arbitrary user-supplied code, or code from the Internet, you are effectively running untrusted Node.js code, and your machine could be compromised. + +If you want to execute _external_ scripts, included via ` +``` + +If you do not control the page, you could try workarounds such as polling for the presence of a specific element. + +For more details, see the discussion in [#640](https://github.com/jsdom/jsdom/issues/640), especially [@matthewkastor](https://github.com/matthewkastor)'s [insightful comment](https://github.com/jsdom/jsdom/issues/640#issuecomment-22216965). + +### Unimplemented parts of the web platform + +Although we enjoy adding new features to jsdom and keeping it up to date with the latest web specs, it has many missing APIs. Please feel free to file an issue for anything missing, but we're a small and busy team, so a pull request might work even better. + +Beyond just features that we haven't gotten to yet, there are two major features that are currently outside the scope of jsdom. These are: + +- **Navigation**: the ability to change the global object, and all other objects, when clicking a link or assigning `location.href` or similar. +- **Layout**: the ability to calculate where elements will be visually laid out as a result of CSS, which impacts methods like `getBoundingClientRects()` or properties like `offsetTop`. + +Currently jsdom has dummy behaviors for some aspects of these features, such as sending a "not implemented" `"jsdomError"` to the virtual console for navigation, or returning zeros for many layout-related properties. Often you can work around these limitations in your code, e.g. by creating new `JSDOM` instances for each page you "navigate" to during a crawl, or using `Object.defineProperty()` to change what various layout-related getters and methods return. + +Note that other tools in the same space, such as PhantomJS, do support these features.
