1 | ### GNU GENERAL PUBLIC LICENSE
2 |
3 | Version 3, 29 June 2007
4 |
5 | Copyright (C) 2007 Free Software Foundation, Inc.
6 |
7 |
8 | Everyone is permitted to copy and distribute verbatim copies of this
9 | license document, but changing it is not allowed.
10 |
11 | ### Preamble
12 |
13 | The GNU General Public License is a free, copyleft license for
14 | software and other kinds of works.
15 |
16 | The licenses for most software and other practical works are designed
17 | to take away your freedom to share and change the works. By contrast,
18 | the GNU General Public License is intended to guarantee your freedom
19 | to share and change all versions of a program--to make sure it remains
20 | free software for all its users. We, the Free Software Foundation, use
21 | the GNU General Public License for most of our software; it applies
22 | also to any other work released this way by its authors. You can apply
23 | it to your programs, too.
24 |
25 | When we speak of free software, we are referring to freedom, not
26 | price. Our General Public Licenses are designed to make sure that you
27 | have the freedom to distribute copies of free software (and charge for
28 | them if you wish), that you receive source code or can get it if you
29 | want it, that you can change the software or use pieces of it in new
30 | free programs, and that you know you can do these things.
31 |
32 | To protect your rights, we need to prevent others from denying you
33 | these rights or asking you to surrender the rights. Therefore, you
34 | have certain responsibilities if you distribute copies of the
35 | software, or if you modify it: responsibilities to respect the freedom
36 | of others.
37 |
38 | For example, if you distribute copies of such a program, whether
39 | gratis or for a fee, you must pass on to the recipients the same
40 | freedoms that you received. You must make sure that they, too, receive
41 | or can get the source code. And you must show them these terms so they
42 | know their rights.
43 |
44 | Developers that use the GNU GPL protect your rights with two steps:
45 | (1) assert copyright on the software, and (2) offer you this License
46 | giving you legal permission to copy, distribute and/or modify it.
47 |
48 | For the developers' and authors' protection, the GPL clearly explains
49 | that there is no warranty for this free software. For both users' and
50 | authors' sake, the GPL requires that modified versions be marked as
51 | changed, so that their problems will not be attributed erroneously to
52 | authors of previous versions.
53 |
54 | Some devices are designed to deny users access to install or run
55 | modified versions of the software inside them, although the
56 | manufacturer can do so. This is fundamentally incompatible with the
57 | aim of protecting users' freedom to change the software. The
58 | systematic pattern of such abuse occurs in the area of products for
59 | individuals to use, which is precisely where it is most unacceptable.
60 | Therefore, we have designed this version of the GPL to prohibit the
61 | practice for those products. If such problems arise substantially in
62 | other domains, we stand ready to extend this provision to those
63 | domains in future versions of the GPL, as needed to protect the
64 | freedom of users.
65 |
66 | Finally, every program is threatened constantly by software patents.
67 | States should not allow patents to restrict development and use of
68 | software on general-purpose computers, but in those that do, we wish
69 | to avoid the special danger that patents applied to a free program
70 | could make it effectively proprietary. To prevent this, the GPL
71 | assures that patents cannot be used to render the program non-free.
72 |
73 | The precise terms and conditions for copying, distribution and
74 | modification follow.
75 |
76 | ### TERMS AND CONDITIONS
77 |
78 | #### 0. Definitions.
79 |
80 | "This License" refers to version 3 of the GNU General Public License.
81 |
82 | "Copyright" also means copyright-like laws that apply to other kinds
83 | of works, such as semiconductor masks.
84 |
85 | "The Program" refers to any copyrightable work licensed under this
86 | License. Each licensee is addressed as "you". "Licensees" and
87 | "recipients" may be individuals or organizations.
88 |
89 | To "modify" a work means to copy from or adapt all or part of the work
90 | in a fashion requiring copyright permission, other than the making of
91 | an exact copy. The resulting work is called a "modified version" of
92 | the earlier work or a work "based on" the earlier work.
93 |
94 | A "covered work" means either the unmodified Program or a work based
95 | on the Program.
96 |
97 | To "propagate" a work means to do anything with it that, without
98 | permission, would make you directly or secondarily liable for
99 | infringement under applicable copyright law, except executing it on a
100 | computer or modifying a private copy. Propagation includes copying,
101 | distribution (with or without modification), making available to the
102 | public, and in some countries other activities as well.
103 |
104 | To "convey" a work means any kind of propagation that enables other
105 | parties to make or receive copies. Mere interaction with a user
106 | through a computer network, with no transfer of a copy, is not
107 | conveying.
108 |
109 | An interactive user interface displays "Appropriate Legal Notices" to
110 | the extent that it includes a convenient and prominently visible
111 | feature that (1) displays an appropriate copyright notice, and (2)
112 | tells the user that there is no warranty for the work (except to the
113 | extent that warranties are provided), that licensees may convey the
114 | work under this License, and how to view a copy of this License. If
115 | the interface presents a list of user commands or options, such as a
116 | menu, a prominent item in the list meets this criterion.
117 |
118 | #### 1. Source Code.
119 |
120 | The "source code" for a work means the preferred form of the work for
121 | making modifications to it. "Object code" means any non-source form of
122 | a work.
123 |
124 | A "Standard Interface" means an interface that either is an official
125 | standard defined by a recognized standards body, or, in the case of
126 | interfaces specified for a particular programming language, one that
127 | is widely used among developers working in that language.
128 |
129 | The "System Libraries" of an executable work include anything, other
130 | than the work as a whole, that (a) is included in the normal form of
131 | packaging a Major Component, but which is not part of that Major
132 | Component, and (b) serves only to enable use of the work with that
133 | Major Component, or to implement a Standard Interface for which an
134 | implementation is available to the public in source code form. A
135 | "Major Component", in this context, means a major essential component
136 | (kernel, window system, and so on) of the specific operating system
137 | (if any) on which the executable work runs, or a compiler used to
138 | produce the work, or an object code interpreter used to run it.
139 |
140 | The "Corresponding Source" for a work in object code form means all
141 | the source code needed to generate, install, and (for an executable
142 | work) run the object code and to modify the work, including scripts to
143 | control those activities. However, it does not include the work's
144 | System Libraries, or general-purpose tools or generally available free
145 | programs which are used unmodified in performing those activities but
146 | which are not part of the work. For example, Corresponding Source
147 | includes interface definition files associated with source files for
148 | the work, and the source code for shared libraries and dynamically
149 | linked subprograms that the work is specifically designed to require,
150 | such as by intimate data communication or control flow between those
151 | subprograms and other parts of the work.
152 |
153 | The Corresponding Source need not include anything that users can
154 | regenerate automatically from other parts of the Corresponding Source.
155 |
156 | The Corresponding Source for a work in source code form is that same
157 | work.
158 |
159 | #### 2. Basic Permissions.
160 |
161 | All rights granted under this License are granted for the term of
162 | copyright on the Program, and are irrevocable provided the stated
163 | conditions are met. This License explicitly affirms your unlimited
164 | permission to run the unmodified Program. The output from running a
165 | covered work is covered by this License only if the output, given its
166 | content, constitutes a covered work. This License acknowledges your
167 | rights of fair use or other equivalent, as provided by copyright law.
168 |
169 | You may make, run and propagate covered works that you do not convey,
170 | without conditions so long as your license otherwise remains in force.
171 | You may convey covered works to others for the sole purpose of having
172 | them make modifications exclusively for you, or provide you with
173 | facilities for running those works, provided that you comply with the
174 | terms of this License in conveying all material for which you do not
175 | control copyright. Those thus making or running the covered works for
176 | you must do so exclusively on your behalf, under your direction and
177 | control, on terms that prohibit them from making any copies of your
178 | copyrighted material outside their relationship with you.
179 |
180 | Conveying under any other circumstances is permitted solely under the
181 | conditions stated below. Sublicensing is not allowed; section 10 makes
182 | it unnecessary.
183 |
184 | #### 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
185 |
186 | No covered work shall be deemed part of an effective technological
187 | measure under any applicable law fulfilling obligations under article
188 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or
189 | similar laws prohibiting or restricting circumvention of such
190 | measures.
191 |
192 | When you convey a covered work, you waive any legal power to forbid
193 | circumvention of technological measures to the extent such
194 | circumvention is effected by exercising rights under this License with
195 | respect to the covered work, and you disclaim any intention to limit
196 | operation or modification of the work as a means of enforcing, against
197 | the work's users, your or third parties' legal rights to forbid
198 | circumvention of technological measures.
199 |
200 | #### 4. Conveying Verbatim Copies.
201 |
202 | You may convey verbatim copies of the Program's source code as you
203 | receive it, in any medium, provided that you conspicuously and
204 | appropriately publish on each copy an appropriate copyright notice;
205 | keep intact all notices stating that this License and any
206 | non-permissive terms added in accord with section 7 apply to the code;
207 | keep intact all notices of the absence of any warranty; and give all
208 | recipients a copy of this License along with the Program.
209 |
210 | You may charge any price or no price for each copy that you convey,
211 | and you may offer support or warranty protection for a fee.
212 |
213 | #### 5. Conveying Modified Source Versions.
214 |
215 | You may convey a work based on the Program, or the modifications to
216 | produce it from the Program, in the form of source code under the
217 | terms of section 4, provided that you also meet all of these
218 | conditions:
219 |
220 | - a) The work must carry prominent notices stating that you modified
221 | it, and giving a relevant date.
222 | - b) The work must carry prominent notices stating that it is
223 | released under this License and any conditions added under
224 | section 7. This requirement modifies the requirement in section 4
225 | to "keep intact all notices".
226 | - c) You must license the entire work, as a whole, under this
227 | License to anyone who comes into possession of a copy. This
228 | License will therefore apply, along with any applicable section 7
229 | additional terms, to the whole of the work, and all its parts,
230 | regardless of how they are packaged. This License gives no
231 | permission to license the work in any other way, but it does not
232 | invalidate such permission if you have separately received it.
233 | - d) If the work has interactive user interfaces, each must display
234 | Appropriate Legal Notices; however, if the Program has interactive
235 | interfaces that do not display Appropriate Legal Notices, your
236 | work need not make them do so.
237 |
238 | A compilation of a covered work with other separate and independent
239 | works, which are not by their nature extensions of the covered work,
240 | and which are not combined with it such as to form a larger program,
241 | in or on a volume of a storage or distribution medium, is called an
242 | "aggregate" if the compilation and its resulting copyright are not
243 | used to limit the access or legal rights of the compilation's users
244 | beyond what the individual works permit. Inclusion of a covered work
245 | in an aggregate does not cause this License to apply to the other
246 | parts of the aggregate.
247 |
248 | #### 6. Conveying Non-Source Forms.
249 |
250 | You may convey a covered work in object code form under the terms of
251 | sections 4 and 5, provided that you also convey the machine-readable
252 | Corresponding Source under the terms of this License, in one of these
253 | ways:
254 |
255 | - a) Convey the object code in, or embodied in, a physical product
256 | (including a physical distribution medium), accompanied by the
257 | Corresponding Source fixed on a durable physical medium
258 | customarily used for software interchange.
259 | - b) Convey the object code in, or embodied in, a physical product
260 | (including a physical distribution medium), accompanied by a
261 | written offer, valid for at least three years and valid for as
262 | long as you offer spare parts or customer support for that product
263 | model, to give anyone who possesses the object code either (1) a
264 | copy of the Corresponding Source for all the software in the
265 | product that is covered by this License, on a durable physical
266 | medium customarily used for software interchange, for a price no
267 | more than your reasonable cost of physically performing this
268 | conveying of source, or (2) access to copy the Corresponding
269 | Source from a network server at no charge.
270 | - c) Convey individual copies of the object code with a copy of the
271 | written offer to provide the Corresponding Source. This
272 | alternative is allowed only occasionally and noncommercially, and
273 | only if you received the object code with such an offer, in accord
274 | with subsection 6b.
275 | - d) Convey the object code by offering access from a designated
276 | place (gratis or for a charge), and offer equivalent access to the
277 | Corresponding Source in the same way through the same place at no
278 | further charge. You need not require recipients to copy the
279 | Corresponding Source along with the object code. If the place to
280 | copy the object code is a network server, the Corresponding Source
281 | may be on a different server (operated by you or a third party)
282 | that supports equivalent copying facilities, provided you maintain
283 | clear directions next to the object code saying where to find the
284 | Corresponding Source. Regardless of what server hosts the
285 | Corresponding Source, you remain obligated to ensure that it is
286 | available for as long as needed to satisfy these requirements.
287 | - e) Convey the object code using peer-to-peer transmission,
288 | provided you inform other peers where the object code and
289 | Corresponding Source of the work are being offered to the general
290 | public at no charge under subsection 6d.
291 |
292 | A separable portion of the object code, whose source code is excluded
293 | from the Corresponding Source as a System Library, need not be
294 | included in conveying the object code work.
295 |
296 | A "User Product" is either (1) a "consumer product", which means any
297 | tangible personal property which is normally used for personal,
298 | family, or household purposes, or (2) anything designed or sold for
299 | incorporation into a dwelling. In determining whether a product is a
300 | consumer product, doubtful cases shall be resolved in favor of
301 | coverage. For a particular product received by a particular user,
302 | "normally used" refers to a typical or common use of that class of
303 | product, regardless of the status of the particular user or of the way
304 | in which the particular user actually uses, or expects or is expected
305 | to use, the product. A product is a consumer product regardless of
306 | whether the product has substantial commercial, industrial or
307 | non-consumer uses, unless such uses represent the only significant
308 | mode of use of the product.
309 |
310 | "Installation Information" for a User Product means any methods,
311 | procedures, authorization keys, or other information required to
312 | install and execute modified versions of a covered work in that User
313 | Product from a modified version of its Corresponding Source. The
314 | information must suffice to ensure that the continued functioning of
315 | the modified object code is in no case prevented or interfered with
316 | solely because modification has been made.
317 |
318 | If you convey an object code work under this section in, or with, or
319 | specifically for use in, a User Product, and the conveying occurs as
320 | part of a transaction in which the right of possession and use of the
321 | User Product is transferred to the recipient in perpetuity or for a
322 | fixed term (regardless of how the transaction is characterized), the
323 | Corresponding Source conveyed under this section must be accompanied
324 | by the Installation Information. But this requirement does not apply
325 | if neither you nor any third party retains the ability to install
326 | modified object code on the User Product (for example, the work has
327 | been installed in ROM).
328 |
329 | The requirement to provide Installation Information does not include a
330 | requirement to continue to provide support service, warranty, or
331 | updates for a work that has been modified or installed by the
332 | recipient, or for the User Product in which it has been modified or
333 | installed. Access to a network may be denied when the modification
334 | itself materially and adversely affects the operation of the network
335 | or violates the rules and protocols for communication across the
336 | network.
337 |
338 | Corresponding Source conveyed, and Installation Information provided,
339 | in accord with this section must be in a format that is publicly
340 | documented (and with an implementation available to the public in
341 | source code form), and must require no special password or key for
342 | unpacking, reading or copying.
343 |
344 | #### 7. Additional Terms.
345 |
346 | "Additional permissions" are terms that supplement the terms of this
347 | License by making exceptions from one or more of its conditions.
348 | Additional permissions that are applicable to the entire Program shall
349 | be treated as though they were included in this License, to the extent
350 | that they are valid under applicable law. If additional permissions
351 | apply only to part of the Program, that part may be used separately
352 | under those permissions, but the entire Program remains governed by
353 | this License without regard to the additional permissions.
354 |
355 | When you convey a copy of a covered work, you may at your option
356 | remove any additional permissions from that copy, or from any part of
357 | it. (Additional permissions may be written to require their own
358 | removal in certain cases when you modify the work.) You may place
359 | additional permissions on material, added by you to a covered work,
360 | for which you have or can give appropriate copyright permission.
361 |
362 | Notwithstanding any other provision of this License, for material you
363 | add to a covered work, you may (if authorized by the copyright holders
364 | of that material) supplement the terms of this License with terms:
365 |
366 | - a) Disclaiming warranty or limiting liability differently from the
367 | terms of sections 15 and 16 of this License; or
368 | - b) Requiring preservation of specified reasonable legal notices or
369 | author attributions in that material or in the Appropriate Legal
370 | Notices displayed by works containing it; or
371 | - c) Prohibiting misrepresentation of the origin of that material,
372 | or requiring that modified versions of such material be marked in
373 | reasonable ways as different from the original version; or
374 | - d) Limiting the use for publicity purposes of names of licensors
375 | or authors of the material; or
376 | - e) Declining to grant rights under trademark law for use of some
377 | trade names, trademarks, or service marks; or
378 | - f) Requiring indemnification of licensors and authors of that
379 | material by anyone who conveys the material (or modified versions
380 | of it) with contractual assumptions of liability to the recipient,
381 | for any liability that these contractual assumptions directly
382 | impose on those licensors and authors.
383 |
384 | All other non-permissive additional terms are considered "further
385 | restrictions" within the meaning of section 10. If the Program as you
386 | received it, or any part of it, contains a notice stating that it is
387 | governed by this License along with a term that is a further
388 | restriction, you may remove that term. If a license document contains
389 | a further restriction but permits relicensing or conveying under this
390 | License, you may add to a covered work material governed by the terms
391 | of that license document, provided that the further restriction does
392 | not survive such relicensing or conveying.
393 |
394 | If you add terms to a covered work in accord with this section, you
395 | must place, in the relevant source files, a statement of the
396 | additional terms that apply to those files, or a notice indicating
397 | where to find the applicable terms.
398 |
399 | Additional terms, permissive or non-permissive, may be stated in the
400 | form of a separately written license, or stated as exceptions; the
401 | above requirements apply either way.
402 |
403 | #### 8. Termination.
404 |
405 | You may not propagate or modify a covered work except as expressly
406 | provided under this License. Any attempt otherwise to propagate or
407 | modify it is void, and will automatically terminate your rights under
408 | this License (including any patent licenses granted under the third
409 | paragraph of section 11).
410 |
411 | However, if you cease all violation of this License, then your license
412 | from a particular copyright holder is reinstated (a) provisionally,
413 | unless and until the copyright holder explicitly and finally
414 | terminates your license, and (b) permanently, if the copyright holder
415 | fails to notify you of the violation by some reasonable means prior to
416 | 60 days after the cessation.
417 |
418 | Moreover, your license from a particular copyright holder is
419 | reinstated permanently if the copyright holder notifies you of the
420 | violation by some reasonable means, this is the first time you have
421 | received notice of violation of this License (for any work) from that
422 | copyright holder, and you cure the violation prior to 30 days after
423 | your receipt of the notice.
424 |
425 | Termination of your rights under this section does not terminate the
426 | licenses of parties who have received copies or rights from you under
427 | this License. If your rights have been terminated and not permanently
428 | reinstated, you do not qualify to receive new licenses for the same
429 | material under section 10.
430 |
431 | #### 9. Acceptance Not Required for Having Copies.
432 |
433 | You are not required to accept this License in order to receive or run
434 | a copy of the Program. Ancillary propagation of a covered work
435 | occurring solely as a consequence of using peer-to-peer transmission
436 | to receive a copy likewise does not require acceptance. However,
437 | nothing other than this License grants you permission to propagate or
438 | modify any covered work. These actions infringe copyright if you do
439 | not accept this License. Therefore, by modifying or propagating a
440 | covered work, you indicate your acceptance of this License to do so.
441 |
442 | #### 10. Automatic Licensing of Downstream Recipients.
443 |
444 | Each time you convey a covered work, the recipient automatically
445 | receives a license from the original licensors, to run, modify and
446 | propagate that work, subject to this License. You are not responsible
447 | for enforcing compliance by third parties with this License.
448 |
449 | An "entity transaction" is a transaction transferring control of an
450 | organization, or substantially all assets of one, or subdividing an
451 | organization, or merging organizations. If propagation of a covered
452 | work results from an entity transaction, each party to that
453 | transaction who receives a copy of the work also receives whatever
454 | licenses to the work the party's predecessor in interest had or could
455 | give under the previous paragraph, plus a right to possession of the
456 | Corresponding Source of the work from the predecessor in interest, if
457 | the predecessor has it or can get it with reasonable efforts.
458 |
459 | You may not impose any further restrictions on the exercise of the
460 | rights granted or affirmed under this License. For example, you may
461 | not impose a license fee, royalty, or other charge for exercise of
462 | rights granted under this License, and you may not initiate litigation
463 | (including a cross-claim or counterclaim in a lawsuit) alleging that
464 | any patent claim is infringed by making, using, selling, offering for
465 | sale, or importing the Program or any portion of it.
466 |
467 | #### 11. Patents.
468 |
469 | A "contributor" is a copyright holder who authorizes use under this
470 | License of the Program or a work on which the Program is based. The
471 | work thus licensed is called the contributor's "contributor version".
472 |
473 | A contributor's "essential patent claims" are all patent claims owned
474 | or controlled by the contributor, whether already acquired or
475 | hereafter acquired, that would be infringed by some manner, permitted
476 | by this License, of making, using, or selling its contributor version,
477 | but do not include claims that would be infringed only as a
478 | consequence of further modification of the contributor version. For
479 | purposes of this definition, "control" includes the right to grant
480 | patent sublicenses in a manner consistent with the requirements of
481 | this License.
482 |
483 | Each contributor grants you a non-exclusive, worldwide, royalty-free
484 | patent license under the contributor's essential patent claims, to
485 | make, use, sell, offer for sale, import and otherwise run, modify and
486 | propagate the contents of its contributor version.
487 |
488 | In the following three paragraphs, a "patent license" is any express
489 | agreement or commitment, however denominated, not to enforce a patent
490 | (such as an express permission to practice a patent or covenant not to
491 | sue for patent infringement). To "grant" such a patent license to a
492 | party means to make such an agreement or commitment not to enforce a
493 | patent against the party.
494 |
495 | If you convey a covered work, knowingly relying on a patent license,
496 | and the Corresponding Source of the work is not available for anyone
497 | to copy, free of charge and under the terms of this License, through a
498 | publicly available network server or other readily accessible means,
499 | then you must either (1) cause the Corresponding Source to be so
500 | available, or (2) arrange to deprive yourself of the benefit of the
501 | patent license for this particular work, or (3) arrange, in a manner
502 | consistent with the requirements of this License, to extend the patent
503 | license to downstream recipients. "Knowingly relying" means you have
504 | actual knowledge that, but for the patent license, your conveying the
505 | covered work in a country, or your recipient's use of the covered work
506 | in a country, would infringe one or more identifiable patents in that
507 | country that you have reason to believe are valid.
508 |
509 | If, pursuant to or in connection with a single transaction or
510 | arrangement, you convey, or propagate by procuring conveyance of, a
511 | covered work, and grant a patent license to some of the parties
512 | receiving the covered work authorizing them to use, propagate, modify
513 | or convey a specific copy of the covered work, then the patent license
514 | you grant is automatically extended to all recipients of the covered
515 | work and works based on it.
516 |
517 | A patent license is "discriminatory" if it does not include within the
518 | scope of its coverage, prohibits the exercise of, or is conditioned on
519 | the non-exercise of one or more of the rights that are specifically
520 | granted under this License. You may not convey a covered work if you
521 | are a party to an arrangement with a third party that is in the
522 | business of distributing software, under which you make payment to the
523 | third party based on the extent of your activity of conveying the
524 | work, and under which the third party grants, to any of the parties
525 | who would receive the covered work from you, a discriminatory patent
526 | license (a) in connection with copies of the covered work conveyed by
527 | you (or copies made from those copies), or (b) primarily for and in
528 | connection with specific products or compilations that contain the
529 | covered work, unless you entered into that arrangement, or that patent
530 | license was granted, prior to 28 March 2007.
531 |
532 | Nothing in this License shall be construed as excluding or limiting
533 | any implied license or other defenses to infringement that may
534 | otherwise be available to you under applicable patent law.
535 |
536 | #### 12. No Surrender of Others' Freedom.
537 |
538 | If conditions are imposed on you (whether by court order, agreement or
539 | otherwise) that contradict the conditions of this License, they do not
540 | excuse you from the conditions of this License. If you cannot convey a
541 | covered work so as to satisfy simultaneously your obligations under
542 | this License and any other pertinent obligations, then as a
543 | consequence you may not convey it at all. For example, if you agree to
544 | terms that obligate you to collect a royalty for further conveying
545 | from those to whom you convey the Program, the only way you could
546 | satisfy both those terms and this License would be to refrain entirely
547 | from conveying the Program.
548 |
549 | #### 13. Use with the GNU Affero General Public License.
550 |
551 | Notwithstanding any other provision of this License, you have
552 | permission to link or combine any covered work with a work licensed
553 | under version 3 of the GNU Affero General Public License into a single
554 | combined work, and to convey the resulting work. The terms of this
555 | License will continue to apply to the part which is the covered work,
556 | but the special requirements of the GNU Affero General Public License,
557 | section 13, concerning interaction through a network will apply to the
558 | combination as such.
559 |
560 | #### 14. Revised Versions of this License.
561 |
562 | The Free Software Foundation may publish revised and/or new versions
563 | of the GNU General Public License from time to time. Such new versions
564 | will be similar in spirit to the present version, but may differ in
565 | detail to address new problems or concerns.
566 |
567 | Each version is given a distinguishing version number. If the Program
568 | specifies that a certain numbered version of the GNU General Public
569 | License "or any later version" applies to it, you have the option of
570 | following the terms and conditions either of that numbered version or
571 | of any later version published by the Free Software Foundation. If the
572 | Program does not specify a version number of the GNU General Public
573 | License, you may choose any version ever published by the Free
574 | Software Foundation.
575 |
576 | If the Program specifies that a proxy can decide which future versions
577 | of the GNU General Public License can be used, that proxy's public
578 | statement of acceptance of a version permanently authorizes you to
579 | choose that version for the Program.
580 |
581 | Later license versions may give you additional or different
582 | permissions. However, no additional obligations are imposed on any
583 | author or copyright holder as a result of your choosing to follow a
584 | later version.
585 |
586 | #### 15. Disclaimer of Warranty.
587 |
588 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
589 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
590 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
591 | WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
592 | LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
593 | A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
594 | PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
595 | DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
596 | CORRECTION.
597 |
598 | #### 16. Limitation of Liability.
599 |
600 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
601 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
602 | CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
603 | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
604 | ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
605 | NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
606 | LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
607 | TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
608 | PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
609 |
610 | #### 17. Interpretation of Sections 15 and 16.
611 |
612 | If the disclaimer of warranty and limitation of liability provided
613 | above cannot be given local legal effect according to their terms,
614 | reviewing courts shall apply local law that most closely approximates
615 | an absolute waiver of all civil liability in connection with the
616 | Program, unless a warranty or assumption of liability accompanies a
617 | copy of the Program in return for a fee.
618 |
619 | END OF TERMS AND CONDITIONS
620 |
621 | ### How to Apply These Terms to Your New Programs
622 |
623 | If you develop a new program, and you want it to be of the greatest
624 | possible use to the public, the best way to achieve this is to make it
625 | free software which everyone can redistribute and change under these
626 | terms.
627 |
628 | To do so, attach the following notices to the program. It is safest to
629 | attach them to the start of each source file to most effectively state
630 | the exclusion of warranty; and each file should have at least the
631 | "copyright" line and a pointer to where the full notice is found.
632 |
633 |
634 | Copyright (C)
635 |
636 | This program is free software: you can redistribute it and/or modify
637 | it under the terms of the GNU General Public License as published by
638 | the Free Software Foundation, either version 3 of the License, or
639 | (at your option) any later version.
640 |
641 | This program is distributed in the hope that it will be useful,
642 | but WITHOUT ANY WARRANTY; without even the implied warranty of
643 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
644 | GNU General Public License for more details.
645 |
646 | You should have received a copy of the GNU General Public License
647 | along with this program. If not, see .
648 |
649 | Also add information on how to contact you by electronic and paper
650 | mail.
651 |
652 | If the program does terminal interaction, make it output a short
653 | notice like this when it starts in an interactive mode:
654 |
655 | Copyright (C)
656 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
657 | This is free software, and you are welcome to redistribute it
658 | under certain conditions; type `show c' for details.
659 |
660 | The hypothetical commands \`show w' and \`show c' should show the
661 | appropriate parts of the General Public License. Of course, your
662 | program's commands might be different; for a GUI interface, you would
663 | use an "about box".
664 |
665 | You should also get your employer (if you work as a programmer) or
666 | school, if any, to sign a "copyright disclaimer" for the program, if
667 | necessary. For more information on this, and how to apply and follow
668 | the GNU GPL, see .
669 |
670 | The GNU General Public License does not permit incorporating your
671 | program into proprietary programs. If your program is a subroutine
672 | library, you may consider it more useful to permit linking proprietary
673 | applications with the library. If this is what you want to do, use the
674 | GNU Lesser General Public License instead of this License. But first,
675 | please read .

1 | # Convert cURL command to Emacs Lisp code
2 | [](https://melpa.org/#/curl-to-elisp)
3 |
4 | _Inspired by [curl-to-Go: Convert curl commands to Go code](https://mholt.github.io/curl-to-go/)._
5 |
6 | ``` emacs-lisp
7 | (curl-to-elisp "curl example.com")
8 | ;; =>
9 | (url-retrieve-synchronously "http://example.com")
10 |
11 | (curl-to-elisp "curl -d 'hello world' example.com")
12 | ;; =>
13 | (let ((url-request-method "POST")
14 | (url-request-extra-headers
15 | '(("Content-Type" . "application/x-www-form-urlencoded")))
16 | (url-request-data "hello world"))
17 | (url-retrieve-synchronously "http://example.com"))
18 | ```
19 |
20 | To get started, try `M-x curl-to-elisp curl -I example.com`, the Emacs Lisp code will be pretty-printed in echo area.
21 |
22 | ## Supported curl options
23 |
24 | The following options are supported, other options are ignored.
25 |
26 | | Option | Note |
27 | |-------------------------------|--------------------------------|
28 | | `-H, --header ` | |
29 | | `-I, --head` | |
30 | | `-X, --request ` | |
31 | | `-d, --data ` | does not interpret `@` as file |
32 | | `--data-ascii ` | |
33 | | `--data-binary ` | |
34 | | `--data-raw ` | |
35 | | `--data-urlencode ` | |
36 | | `-F, --form ` | does not interpret `@` as file |
37 | | `--form-string ` | |
38 | | `-A, --user-agent ` | |
39 | | `-e, --referer ` | |
40 | | `--url ` | |
41 | | `-u, --user ` | does not prompt for a password |
42 | | `-s, --silent` | |
43 |
44 | ### `-L`, `--location`
45 |
46 | Regarding the location header, curl doesn't redirect unless you use `-L`,
47 | `--location`, however, `url-retrieve[-synchronously]` DOES automatically
48 | redirect, to inhibit redirection, let-binding `url-max-redirections`, e.g.,
49 |
50 | ``` emacs-lisp
51 | (let ((url-max-redirections 0))
52 | (display-buffer
53 | (url-retrieve-synchronously "http://emacs-china.org")))
54 | ```
55 |
56 | ## httpie to elisp
57 |
58 | `curl-to-elisp-httpie-to-elisp` uses [curlie](https://curlie.io/) to
59 | transform an [httpie](https://httpie.org/)/curlie command to elisp.
60 |
61 | You need to have `curlie` binary in your path (or customize
62 | `curl-to-elisp-curlie-binary`).
63 |
64 | ## curl to [verb](https://github.com/federicotdn/verb)
65 |
66 | `curl-to-elisp-verb` converts curl command to verb request specification.
67 |
68 | ## Dependencies
69 |
70 | - Emacs 25.1
