By contrast, 15 | the GNU General Public License is intended to guarantee your freedom to 16 | share and change all versions of a program--to make sure it remains free 17 | software for all its users. We, the Free Software Foundation, use the 18 | GNU General Public License for most of our software; it applies also to 19 | any other work released this way by its authors. You can apply it to 20 | your programs, too. 21 | 22 | When we speak of free software, we are referring to freedom, not 23 | price. Our General Public Licenses are designed to make sure that you 24 | have the freedom to distribute copies of free software (and charge for 25 | them if you wish), that you receive source code or can get it if you 26 | want it, that you can change the software or use pieces of it in new 27 | free programs, and that you know you can do these things. 28 | 29 | To protect your rights, we need to prevent others from denying you 30 | these rights or asking you to surrender the rights. Therefore, you have 31 | certain responsibilities if you distribute copies of the software, or if 32 | you modify it: responsibilities to respect the freedom of others. 33 | 34 | For example, if you distribute copies of such a program, whether 35 | gratis or for a fee, you must pass on to the recipients the same 36 | freedoms that you received. You must make sure that they, too, receive 37 | or can get the source code. And you must show them these terms so they 38 | know their rights. 39 | 40 | Developers that use the GNU GPL protect your rights with two steps: 41 | (1) assert copyright on the software, and (2) offer you this License 42 | giving you legal permission to copy, distribute and/or modify it. 43 | 44 | For the developers' and authors' protection, the GPL clearly explains 45 | that there is no warranty for this free software. For both users' and 46 | authors' sake, the GPL requires that modified versions be marked as 47 | changed, so that their problems will not be attributed erroneously to 48 | authors of previous versions. 49 | 50 | Some devices are designed to deny users access to install or run 51 | modified versions of the software inside them, although the manufacturer 52 | can do so. This is fundamentally incompatible with the aim of 53 | protecting users' freedom to change the software. The systematic 54 | pattern of such abuse occurs in the area of products for individuals to 55 | use, which is precisely where it is most unacceptable. Therefore, we 56 | have designed this version of the GPL to prohibit the practice for those 57 | products. If such problems arise substantially in other domains, we 58 | stand ready to extend this provision to those domains in future versions 59 | of the GPL, as needed to protect the freedom of users. 60 | 61 | Finally, every program is threatened constantly by software patents. 62 | States should not allow patents to restrict development and use of 63 | software on general-purpose computers, but in those that do, we wish to 64 | avoid the special danger that patents applied to a free program could 65 | make it effectively proprietary. To prevent this, the GPL assures that 66 | patents cannot be used to render the program non-free. 67 | 68 | The precise terms and conditions for copying, distribution and 69 | modification follow. 70 | 71 | TERMS AND CONDITIONS 72 | 73 | 0. Definitions. 74 | 75 | "This License" refers to version 3 of the GNU General Public License. 76 | 77 | "Copyright" also means copyright-like laws that apply to other kinds of 78 | works, such as semiconductor masks. 79 | 80 | "The Program" refers to any copyrightable work licensed under this 81 | License. Each licensee is addressed as "you". "Licensees" and 82 | "recipients" may be individuals or organizations. 83 | 84 | To "modify" a work means to copy from or adapt all or part of the work 85 | in a fashion requiring copyright permission, other than the making of an 86 | exact copy. The resulting work is called a "modified version" of the 87 | earlier work or a work "based on" the earlier work. 88 | 89 | A "covered work" means either the unmodified Program or a work based 90 | on the Program. 91 | 92 | To "propagate" a work means to do anything with it that, without 93 | permission, would make you directly or secondarily liable for 94 | infringement under applicable copyright law, except executing it on a 95 | computer or modifying a private copy. Propagation includes copying, 96 | distribution (with or without modification), making available to the 97 | public, and in some countries other activities as well. 98 | 99 | To "convey" a work means any kind of propagation that enables other 100 | parties to make or receive copies. Mere interaction with a user through 101 | a computer network, with no transfer of a copy, is not conveying. 102 | 103 | An interactive user interface displays "Appropriate Legal Notices" 104 | to the extent that it includes a convenient and prominently visible 105 | feature that (1) displays an appropriate copyright notice, and (2) 106 | tells the user that there is no warranty for the work (except to the 107 | extent that warranties are provided), that licensees may convey the 108 | work under this License, and how to view a copy of this License. If 109 | the interface presents a list of user commands or options, such as a 110 | menu, a prominent item in the list meets this criterion. 111 | 112 | 1. Source Code. 113 | 114 | The "source code" for a work means the preferred form of the work 115 | for making modifications to it. "Object code" means any non-source 116 | form of a work. 117 | 118 | A "Standard Interface" means an interface that either is an official 119 | standard defined by a recognized standards body, or, in the case of 120 | interfaces specified for a particular programming language, one that 121 | is widely used among developers working in that language. 122 | 123 | The "System Libraries" of an executable work include anything, other 124 | than the work as a whole, that (a) is included in the normal form of 125 | packaging a Major Component, but which is not part of that Major 126 | Component, and (b) serves only to enable use of the work with that 127 | Major Component, or to implement a Standard Interface for which an 128 | implementation is available to the public in source code form. A 129 | "Major Component", in this context, means a major essential component 130 | (kernel, window system, and so on) of the specific operating system 131 | (if any) on which the executable work runs, or a compiler used to 132 | produce the work, or an object code interpreter used to run it. 133 | 134 | The "Corresponding Source" for a work in object code form means all 135 | the source code needed to generate, install, and (for an executable 136 | work) run the object code and to modify the work, including scripts to 137 | control those activities. However, it does not include the work's 138 | System Libraries, or general-purpose tools or generally available free 139 | programs which are used unmodified in performing those activities but 140 | which are not part of the work. For example, Corresponding Source 141 | includes interface definition files associated with source files for 142 | the work, and the source code for shared libraries and dynamically 143 | linked subprograms that the work is specifically designed to require, 144 | such as by intimate data communication or control flow between those 145 | subprograms and other parts of the work. 146 | 147 | The Corresponding Source need not include anything that users 148 | can regenerate automatically from other parts of the Corresponding 149 | Source. 150 | 151 | The Corresponding Source for a work in source code form is that 152 | same work. 153 | 154 | 2. Basic Permissions. 155 | 156 | All rights granted under this License are granted for the term of 157 | copyright on the Program, and are irrevocable provided the stated 158 | conditions are met. This License explicitly affirms your unlimited 159 | permission to run the unmodified Program. The output from running a 160 | covered work is covered by this License only if the output, given its 161 | content, constitutes a covered work. This License acknowledges your 162 | rights of fair use or other equivalent, as provided by copyright law. 163 | 164 | You may make, run and propagate covered works that you do not 165 | convey, without conditions so long as your license otherwise remains 166 | in force. You may convey covered works to others for the sole purpose 167 | of having them make modifications exclusively for you, or provide you 168 | with facilities for running those works, provided that you comply with 169 | the terms of this License in conveying all material for which you do 170 | not control copyright. Those thus making or running the covered works 171 | for you must do so exclusively on your behalf, under your direction 172 | and control, on terms that prohibit them from making any copies of 173 | your copyrighted material outside their relationship with you. 174 | 175 | Conveying under any other circumstances is permitted solely under 176 | the conditions stated below. Sublicensing is not allowed; section 10 177 | makes it unnecessary. 178 | 179 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 180 | 181 | No covered work shall be deemed part of an effective technological 182 | measure under any applicable law fulfilling obligations under article 183 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or 184 | similar laws prohibiting or restricting circumvention of such 185 | measures. 186 | 187 | When you convey a covered work, you waive any legal power to forbid 188 | circumvention of technological measures to the extent such circumvention 189 | is effected by exercising rights under this License with respect to 190 | the covered work, and you disclaim any intention to limit operation or 191 | modification of the work as a means of enforcing, against the work's 192 | users, your or third parties' legal rights to forbid circumvention of 193 | technological measures. 194 | 195 | 4. Conveying Verbatim Copies. 196 | 197 | You may convey verbatim copies of the Program's source code as you 198 | receive it, in any medium, provided that you conspicuously and 199 | appropriately publish on each copy an appropriate copyright notice; 200 | keep intact all notices stating that this License and any 201 | non-permissive terms added in accord with section 7 apply to the code; 202 | keep intact all notices of the absence of any warranty; and give all 203 | recipients a copy of this License along with the Program. 204 | 205 | You may charge any price or no price for each copy that you convey, 206 | and you may offer support or warranty protection for a fee. 207 | 208 | 5. Conveying Modified Source Versions. 209 | 210 | You may convey a work based on the Program, or the modifications to 211 | produce it from the Program, in the form of source code under the 212 | terms of section 4, provided that you also meet all of these conditions: 213 | 214 | a) The work must carry prominent notices stating that you modified 215 | it, and giving a relevant date. 216 | 217 | b) The work must carry prominent notices stating that it is 218 | released under this License and any conditions added under section 219 | 7. This requirement modifies the requirement in section 4 to 220 | "keep intact all notices". 221 | 222 | c) You must license the entire work, as a whole, under this 223 | License to anyone who comes into possession of a copy. This 224 | License will therefore apply, along with any applicable section 7 225 | additional terms, to the whole of the work, and all its parts, 226 | regardless of how they are packaged. This License gives no 227 | permission to license the work in any other way, but it does not 228 | invalidate such permission if you have separately received it. 229 | 230 | d) If the work has interactive user interfaces, each must display 231 | Appropriate Legal Notices; however, if the Program has interactive 232 | interfaces that do not display Appropriate Legal Notices, your 233 | work need not make them do so. 234 | 235 | A compilation of a covered work with other separate and independent 236 | works, which are not by their nature extensions of the covered work, 237 | and which are not combined with it such as to form a larger program, 238 | in or on a volume of a storage or distribution medium, is called an 239 | "aggregate" if the compilation and its resulting copyright are not 240 | used to limit the access or legal rights of the compilation's users 241 | beyond what the individual works permit. Inclusion of a covered work 242 | in an aggregate does not cause this License to apply to the other 243 | parts of the aggregate. 244 | 245 | 6. Conveying Non-Source Forms. 246 | 247 | You may convey a covered work in object code form under the terms 248 | of sections 4 and 5, provided that you also convey the 249 | machine-readable Corresponding Source under the terms of this License, 250 | in one of these ways: 251 | 252 | a) Convey the object code in, or embodied in, a physical product 253 | (including a physical distribution medium), accompanied by the 254 | Corresponding Source fixed on a durable physical medium 255 | customarily used for software interchange. 256 | 257 | b) Convey the object code in, or embodied in, a physical product 258 | (including a physical distribution medium), accompanied by a 259 | written offer, valid for at least three years and valid for as 260 | long as you offer spare parts or customer support for that product 261 | model, to give anyone who possesses the object code either (1) a 262 | copy of the Corresponding Source for all the software in the 263 | product that is covered by this License, on a durable physical 264 | medium customarily used for software interchange, for a price no 265 | more than your reasonable cost of physically performing this 266 | conveying of source, or (2) access to copy the 267 | Corresponding Source from a network server at no charge. 268 | 269 | c) Convey individual copies of the object code with a copy of the 270 | written offer to provide the Corresponding Source. This 271 | alternative is allowed only occasionally and noncommercially, and 272 | only if you received the object code with such an offer, in accord 273 | with subsection 6b. 274 | 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 | 288 | e) Convey the object code using peer-to-peer transmission, provided 289 | you inform other peers where the object code and Corresponding 290 | Source of the work are being offered to the general public at no 291 | charge under subsection 6d. 292 | 293 | A separable portion of the object code, whose source code is excluded 294 | from the Corresponding Source as a System Library, need not be 295 | included in conveying the object code work. 296 | 297 | A "User Product" is either (1) a "consumer product", which means any 298 | tangible personal property which is normally used for personal, family, 299 | or household purposes, or (2) anything designed or sold for incorporation 300 | into a dwelling. In determining whether a product is a consumer product, 301 | doubtful cases shall be resolved in favor of coverage. For a particular 302 | product received by a particular user, "normally used" refers to a 303 | typical or common use of that class of product, regardless of the status 304 | of the particular user or of the way in which the particular user 305 | actually uses, or expects or is expected to use, the product. A product 306 | is a consumer product regardless of whether the product has substantial 307 | commercial, industrial or non-consumer uses, unless such uses represent 308 | the only significant 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 install 312 | and execute modified versions of a covered work in that User Product from 313 | a modified version of its Corresponding Source. The information must 314 | suffice to ensure that the continued functioning of the modified object 315 | code is in no case prevented or interfered with solely because 316 | 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 updates 331 | for a work that has been modified or installed by the recipient, or for 332 | the User Product in which it has been modified or installed. Access to a 333 | network may be denied when the modification itself materially and 334 | adversely affects the operation of the network or violates the rules and 335 | protocols for communication across the network. 336 | 337 | Corresponding Source conveyed, and Installation Information provided, 338 | in accord with this section must be in a format that is publicly 339 | documented (and with an implementation available to the public in 340 | source code form), and must require no special password or key for 341 | unpacking, reading or copying. 342 | 343 | 7. Additional Terms. 344 | 345 | "Additional permissions" are terms that supplement the terms of this 346 | License by making exceptions from one or more of its conditions. 347 | Additional permissions that are applicable to the entire Program shall 348 | be treated as though they were included in this License, to the extent 349 | that they are valid under applicable law. If additional permissions 350 | apply only to part of the Program, that part may be used separately 351 | under those permissions, but the entire Program remains governed by 352 | this License without regard to the additional permissions. 353 | 354 | When you convey a copy of a covered work, you may at your option 355 | remove any additional permissions from that copy, or from any part of 356 | it. (Additional permissions may be written to require their own 357 | removal in certain cases when you modify the work.) You may place 358 | additional permissions on material, added by you to a covered work, 359 | for which you have or can give appropriate copyright permission. 360 | 361 | Notwithstanding any other provision of this License, for material you 362 | add to a covered work, you may (if authorized by the copyright holders of 363 | that material) supplement the terms of this License with terms: 364 | 365 | a) Disclaiming warranty or limiting liability differently from the 366 | terms of sections 15 and 16 of this License; or 367 | 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 | 372 | c) Prohibiting misrepresentation of the origin of that material, or 373 | requiring that modified versions of such material be marked in 374 | reasonable ways as different from the original version; or 375 | 376 | d) Limiting the use for publicity purposes of names of licensors or 377 | authors of the material; or 378 | 379 | e) Declining to grant rights under trademark law for use of some 380 | trade names, trademarks, or service marks; or 381 | 382 | f) Requiring indemnification of licensors and authors of that 383 | material by anyone who conveys the material (or modified versions of 384 | it) with contractual assumptions of liability to the recipient, for 385 | any liability that these contractual assumptions directly impose on 386 | those licensors and authors. 387 | 388 | All other non-permissive additional terms are considered "further 389 | restrictions" within the meaning of section 10. If the Program as you 390 | received it, or any part of it, contains a notice stating that it is 391 | governed by this License along with a term that is a further 392 | restriction, you may remove that term. If a license document contains 393 | a further restriction but permits relicensing or conveying under this 394 | License, you may add to a covered work material governed by the terms 395 | of that license document, provided that the further restriction does 396 | not survive such relicensing or conveying. 397 | 398 | If you add terms to a covered work in accord with this section, you 399 | must place, in the relevant source files, a statement of the 400 | additional terms that apply to those files, or a notice indicating 401 | where to find the applicable terms. 402 | 403 | Additional terms, permissive or non-permissive, may be stated in the 404 | form of a separately written license, or stated as exceptions; 405 | the above requirements apply either way. 406 | 407 | 8. Termination. 408 | 409 | You may not propagate or modify a covered work except as expressly 410 | provided under this License. Any attempt otherwise to propagate or 411 | modify it is void, and will automatically terminate your rights under 412 | this License (including any patent licenses granted under the third 413 | paragraph of section 11). 414 | 415 | However, if you cease all violation of this License, then your 416 | license from a particular copyright holder is reinstated (a) 417 | provisionally, unless and until the copyright holder explicitly and 418 | finally terminates your license, and (b) permanently, if the copyright 419 | holder fails to notify you of the violation by some reasonable means 420 | prior to 60 days after the cessation. 421 | 422 | Moreover, your license from a particular copyright holder is 423 | reinstated permanently if the copyright holder notifies you of the 424 | violation by some reasonable means, this is the first time you have 425 | received notice of violation of this License (for any work) from that 426 | copyright holder, and you cure the violation prior to 30 days after 427 | your receipt of the notice. 428 | 429 | Termination of your rights under this section does not terminate the 430 | licenses of parties who have received copies or rights from you under 431 | this License. If your rights have been terminated and not permanently 432 | reinstated, you do not qualify to receive new licenses for the same 433 | material under section 10. 434 | 435 | 9. Acceptance Not Required for Having Copies. 436 | 437 | You are not required to accept this License in order to receive or 438 | run a copy of the Program. Ancillary propagation of a covered work 439 | occurring solely as a consequence of using peer-to-peer transmission 440 | to receive a copy likewise does not require acceptance. However, 441 | nothing other than this License grants you permission to propagate or 442 | modify any covered work. These actions infringe copyright if you do 443 | not accept this License. Therefore, by modifying or propagating a 444 | covered work, you indicate your acceptance of this License to do so. 445 | 446 | 10. Automatic Licensing of Downstream Recipients. 447 | 448 | Each time you convey a covered work, the recipient automatically 449 | receives a license from the original licensors, to run, modify and 450 | propagate that work, subject to this License. You are not responsible 451 | for enforcing compliance by third parties with this License. 452 | 453 | An "entity transaction" is a transaction transferring control of an 454 | organization, or substantially all assets of one, or subdividing an 455 | organization, or merging organizations. If propagation of a covered 456 | work results from an entity transaction, each party to that 457 | transaction who receives a copy of the work also receives whatever 458 | licenses to the work the party's predecessor in interest had or could 459 | give under the previous paragraph, plus a right to possession of the 460 | Corresponding Source of the work from the predecessor in interest, if 461 | the predecessor has it or can get it with reasonable efforts. 462 | 463 | You may not impose any further restrictions on the exercise of the 464 | rights granted or affirmed under this License. For example, you may 465 | not impose a license fee, royalty, or other charge for exercise of 466 | rights granted under this License, and you may not initiate litigation 467 | (including a cross-claim or counterclaim in a lawsuit) alleging that 468 | any patent claim is infringed by making, using, selling, offering for 469 | sale, or importing the Program or any portion of it. 470 | 471 | 11. Patents. 472 | 473 | A "contributor" is a copyright holder who authorizes use under this 474 | License of the Program or a work on which the Program is based. The 475 | work thus licensed is called the contributor's "contributor version". 476 | 477 | A contributor's "essential patent claims" are all patent claims 478 | owned or controlled by the contributor, whether already acquired or 479 | hereafter acquired, that would be infringed by some manner, permitted 480 | by this License, of making, using, or selling its contributor version, 481 | but do not include claims that would be infringed only as a 482 | consequence of further modification of the contributor version. For 483 | purposes of this definition, "control" includes the right to grant 484 | patent sublicenses in a manner consistent with the requirements of 485 | this License. 486 | 487 | Each contributor grants you a non-exclusive, worldwide, royalty-free 488 | patent license under the contributor's essential patent claims, to 489 | make, use, sell, offer for sale, import and otherwise run, modify and 490 | propagate the contents of its contributor version. 491 | 492 | In the following three paragraphs, a "patent license" is any express 493 | agreement or commitment, however denominated, not to enforce a patent 494 | (such as an express permission to practice a patent or covenant not to 495 | sue for patent infringement). To "grant" such a patent license to a 496 | party means to make such an agreement or commitment not to enforce a 497 | patent against the party. 498 | 499 | If you convey a covered work, knowingly relying on a patent license, 500 | and the Corresponding Source of the work is not available for anyone 501 | to copy, free of charge and under the terms of this License, through a 502 | publicly available network server or other readily accessible means, 503 | then you must either (1) cause the Corresponding Source to be so 504 | available, or (2) arrange to deprive yourself of the benefit of the 505 | patent license for this particular work, or (3) arrange, in a manner 506 | consistent with the requirements of this License, to extend the patent 507 | license to downstream recipients. "Knowingly relying" means you have 508 | actual knowledge that, but for the patent license, your conveying the 509 | covered work in a country, or your recipient's use of the covered work 510 | in a country, would infringe one or more identifiable patents in that 511 | country that you have reason to believe are valid. 512 | 513 | If, pursuant to or in connection with a single transaction or 514 | arrangement, you convey, or propagate by procuring conveyance of, a 515 | covered work, and grant a patent license to some of the parties 516 | receiving the covered work authorizing them to use, propagate, modify 517 | or convey a specific copy of the covered work, then the patent license 518 | you grant is automatically extended to all recipients of the covered 519 | work and works based on it. 520 | 521 | A patent license is "discriminatory" if it does not include within 522 | the scope of its coverage, prohibits the exercise of, or is 523 | conditioned on the non-exercise of one or more of the rights that are 524 | specifically granted under this License. You may not convey a covered 525 | work if you are a party to an arrangement with a third party that is 526 | in the business of distributing software, under which you make payment 527 | to the third party based on the extent of your activity of conveying 528 | the work, and under which the third party grants, to any of the 529 | parties who would receive the covered work from you, a discriminatory 530 | patent license (a) in connection with copies of the covered work 531 | conveyed by you (or copies made from those copies), or (b) primarily 532 | for and in connection with specific products or compilations that 533 | contain the covered work, unless you entered into that arrangement, 534 | or that patent license was granted, prior to 28 March 2007. 535 | 536 | Nothing in this License shall be construed as excluding or limiting 537 | any implied license or other defenses to infringement that may 538 | otherwise be available to you under applicable patent law. 539 | 540 | 12. No Surrender of Others' Freedom. 541 | 542 | If conditions are imposed on you (whether by court order, agreement or 543 | otherwise) that contradict the conditions of this License, they do not 544 | excuse you from the conditions of this License. If you cannot convey a 545 | covered work so as to satisfy simultaneously your obligations under this 546 | License and any other pertinent obligations, then as a consequence you may 547 | not convey it at all. For example, if you agree to terms that obligate you 548 | to collect a royalty for further conveying from those to whom you convey 549 | the Program, the only way you could satisfy both those terms and this 550 | License would be to refrain entirely from conveying the Program. 551 | 552 | 13. Use with the GNU Affero General Public License. 553 | 554 | Notwithstanding any other provision of this License, you have 555 | permission to link or combine any covered work with a work licensed 556 | under version 3 of the GNU Affero General Public License into a single 557 | combined work, and to convey the resulting work. The terms of this 558 | License will continue to apply to the part which is the covered work, 559 | but the special requirements of the GNU Affero General Public License, 560 | section 13, concerning interaction through a network will apply to the 561 | combination as such. 562 | 563 | 14. Revised Versions of this License. 564 | 565 | The Free Software Foundation may publish revised and/or new versions of 566 | the GNU General Public License from time to time. Such new versions will 567 | be similar in spirit to the present version, but may differ in detail to 568 | address new problems or concerns. 569 | 570 | Each version is given a distinguishing version number. If the 571 | Program specifies that a certain numbered version of the GNU General 572 | Public License "or any later version" applies to it, you have the 573 | option of following the terms and conditions either of that numbered 574 | version or of any later version published by the Free Software 575 | Foundation. If the Program does not specify a version number of the 576 | GNU General Public License, you may choose any version ever published 577 | by the Free Software Foundation. 578 | 579 | If the Program specifies that a proxy can decide which future 580 | versions of the GNU General Public License can be used, that proxy's 581 | public statement of acceptance of a version permanently authorizes you 582 | to choose that version for the Program. 583 | 584 | Later license versions may give you additional or different 585 | permissions. However, no additional obligations are imposed on any 586 | author or copyright holder as a result of your choosing to follow a 587 | later version. 588 | 589 | 15. Disclaimer of Warranty. 590 | 591 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 592 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 593 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 594 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 595 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 596 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 597 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 598 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 599 | 600 | 16. Limitation of Liability. 601 | 602 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 603 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 604 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 605 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 606 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 607 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 608 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 609 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 610 | SUCH DAMAGES. 611 | 612 | 17. Interpretation of Sections 15 and 16. 613 | 614 | If the disclaimer of warranty and limitation of liability provided 615 | above cannot be given local legal effect according to their terms, 616 | reviewing courts shall apply local law that most closely approximates 617 | an absolute waiver of all civil liability in connection with the 618 | Program, unless a warranty or assumption of liability accompanies a 619 | copy of the Program in return for a fee. 620 | 621 | END OF TERMS AND CONDITIONS 622 | 623 | How to Apply These Terms to Your New Programs 624 | 625 | If you develop a new program, and you want it to be of the greatest 626 | possible use to the public, the best way to achieve this is to make it 627 | free software which everyone can redistribute and change under these terms. 628 | 629 | To do so, attach the following notices to the program. It is safest 630 | to attach them to the start of each source file to most effectively 631 | state the exclusion of warranty; and each file should have at least 632 | the "copyright" line and a pointer to where the full notice is found. 633 | 634 | 635 | Copyright (C) 636 | 637 | This program is free software: you can redistribute it and/or modify 638 | it under the terms of the GNU General Public License as published by 639 | the Free Software Foundation, either version 3 of the License, or 640 | (at your option) any later version. 641 | 642 | This program is distributed in the hope that it will be useful, 643 | but WITHOUT ANY WARRANTY; without even the implied warranty of 644 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 645 | GNU General Public License for more details. 646 | 647 | You should have received a copy of the GNU General Public License 648 | along with this program. If not, see . 649 | 650 | Also add information on how to contact you by electronic and paper 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 appropriate 661 | parts of the General Public License. Of course, your program's commands 662 | might be different; for a GUI interface, you would use an "about box". 663 | 664 | You should also get your employer (if you work as a programmer) or school, 665 | if any, to sign a "copyright disclaimer" for the program, if necessary. 666 | For more information on this, and how to apply and follow the GNU GPL, see 667 | . 668 | 669 | The GNU General Public License does not permit incorporating your program 670 | into proprietary programs. If your program is a subroutine library, you 671 | may consider it more useful to permit linking proprietary applications with 672 | the library. If this is what you want to do, use the GNU Lesser General 673 | Public License instead of this License. But first, please read 674 | . 675 | -------------------------------------------------------------------------------- /Makefile: -------------------------------------------------------------------------------- 1 | # Makefile 2 | 3 | VERSION = 0.1 4 | PKG_CONFIG = pkg-config 5 | 6 | USR_LOCAL_BIN = /usr/local/bin 7 | USR_SHARE = /usr/share 8 | 9 | XWAYLAND = 10 | XLIBS = 11 | #XWAYLAND = -DXWAYLAND 12 | #XLIBS = xcb xcb-icccm 13 | 14 | # FLAGS 15 | CFLAGS = -I. -DWLR_USE_UNSTABLE -D_POSIX_C_SOURCE=200809L -DVERSION=\"$(VERSION)\" $(XWAYLAND) 16 | DEVCFLAGS = -pedantic -Wall -Wextra -Wno-unused-parameter -Wno-sign-compare -Wshadow -Wunused-macros -Werror=implicit -Werror=return-type -Werror=incompatible-pointer-types -lm -O3 -ggdb 17 | 18 | # CFLAGS / LDFLAGS 19 | PKGS = wlroots-0.18 wayland-server xkbcommon libinput lua $(XLIBS) pixman-1 20 | HELLWMCFLAGS = `$(PKG_CONFIG) --cflags $(PKGS)` $(CFLAGS) $(DEVCFLAGS) 21 | LDLIBS = `$(PKG_CONFIG) --libs $(PKGS)` $(LIBS) 22 | 23 | all: hellwm hellcli 24 | hellwm: hellwm.o 25 | $(CC) hellwm.o $(LDLIBS) $(LDFLAGS) $(HELLWMCFLAGS) -o $@ 26 | hellwm.o: hellwm.c cursor-shape-v1-protocol.h xdg-shell-protocol.h wlr-layer-shell-unstable-v1-protocol.h 27 | 28 | # WAYLAND 29 | WAYLAND_SCANNER = `$(PKG_CONFIG) --variable=wayland_scanner wayland-scanner` 30 | WAYLAND_PROTOCOLS = `$(PKG_CONFIG) --variable=pkgdatadir wayland-protocols` 31 | 32 | xdg-shell-protocol.h: 33 | $(WAYLAND_SCANNER) server-header \ 34 | $(WAYLAND_PROTOCOLS)/stable/xdg-shell/xdg-shell.xml $@ 35 | wlr-layer-shell-unstable-v1-protocol.h: 36 | $(WAYLAND_SCANNER) server-header \ 37 | protocols/wlr-layer-shell-unstable-v1.xml $@ 38 | cursor-shape-v1-protocol.h: 39 | $(WAYLAND_SCANNER) server-header \ 40 | $(WAYLAND_PROTOCOLS)/staging/cursor-shape/cursor-shape-v1.xml $@ 41 | 42 | hellcli: 43 | $(CC) hellcli.c -o $@ 44 | 45 | clean: 46 | rm -f hellwm hellcli *.o *-protocol.h *.log 47 | 48 | # CREATE PACKAGE 49 | release: clean 50 | mkdir -p hellwm-$(VERSION) 51 | cp -R LICENSE* Makefile README.md protocols hellwm.c hellwm-$(VERSION) 52 | tar -caf hellwm-$(VERSION).tar.gz hellwm-$(VERSION) 53 | rm -rf hellwm-$(VERSION) 54 | 55 | install: hellwm 56 | mkdir -p $(USR_LOCAL_BIN) 57 | cp -f hellwm $(USR_LOCAL_BIN) 58 | chmod 755 $(USR_LOCAL_BIN)/hellwm # chmod u=rwx,g=rx,o=rx 59 | mkdir -p $(USR_SHARE)/wayland-sessions 60 | cp -f hellwm.desktop $(USR_SHARE)/wayland-sessions/hellwm.desktop 61 | chmod 644 $(USR_SHARE)/wayland-sessions/hellwm.desktop # chmod u=rwx,g=rx,o=rx 62 | uninstall: 63 | rm -f $(USR_LOCAL_BIN)/hellwm $(USR_SHARE)/wayland-sessions/hellwm.desktop 64 | 65 | .SUFFIXES: .c .o 66 | .c.o: 67 | $(CC) $(CPPFLAGS) $(HELLWMCFLAGS) -c $< 68 | 69 | .PHONY: hellwm clean release install uninstall 70 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # HellWM Wayland Compositor 2 | 3 | ## Why? 4 | I got inspired by Vaxry, I thoguht that if someone from my country could create 'base' for Hyprland in a month, I should try writing my own WaylandCompositor too - it can't be that hard... right?

20 | Binary Workspaces (Click to expand) 21 | 22 | ## You can use less amount of keys to switch between workspaces! 23 | 24 | Concept: 25 | 26 | You can switch between **15 workspaces** just by using combinations of only **4 keys**! 27 | 28 | Each key represents a binary value, and by combining them, you can achieve more funtionality with less clicks! 29 | 30 | Keys and Binary Values: 31 | 32 | Key 1: 33 | 1 = 0001 34 | 35 | Key 2: 36 | 2 = 0010 37 | 38 | Key 3 39 | 4 = 0100 40 | 41 | Key 4 42 | 8 = 1000 43 | 44 | By adding the binary values of the pressed keys, you determine the workspace number. 45 | Examples: 46 | 47 | Pressing Key 1 and Key 3 together: 48 | 49 | Key 1 + Key 3 = 0001 + 0100 = 0101 50 | Result: 1 0 1 0 51 | 52 | Binary Values: 1 (Key 1) + 4 (Key 3) = 5 53 | Workspace: 5 54 | 55 | Pressing only Key 2: 56 | Key 2 = 0 1 0 0 57 | Result = 0 1 0 0 58 | 59 | Binary Values: 2 (Key 2) = 2 60 | Workspace: 2 61 | 62 | Configuration: 63 | 64 | Here’s how the configuration works: 65 | 66 | #### Normal Workspaces: You can assign individual workspaces to single keys. For example: 67 | 68 | ```lua 69 | bind( 70 | "Super_L, 1", -- keys 71 | "workspace", -- specify that it is a workspace 72 | 1, -- workspace number 73 | false, -- binary workspaces enabled 74 | 1, -- binary workspaces value 75 | true -- also move active window to this workspace (not working rn) 76 | ) 77 | ``` 78 | 79 | ```lua 80 | bind("Super_L, 2", "workspace", 2, false, 0) -- Switch to workspace 2 81 | ``` 82 | 83 | #### Binary Workspaces: If you enable binary mode, keys combine to generate workspace numbers: 84 | 85 | ```lua 86 | bind("Super_L, u", "workspace", 1, true, 1, true) -- Key 'u' represents Binary 1 87 | ``` 88 | 89 | ```lua 90 | bind("Super_L, i", "workspace", 2, true, 2, false) -- Key 'i' represents Binary 2 91 | ``` 92 | 93 | ```lua 94 | bind("Super_L, o", "workspace", 3, true, 4, false) -- Key 'o' represents Binary 4 95 | ``` 96 | 97 | ```lua 98 | bind("Super_L, p", "workspace", 4, true, 8, false) -- Key 'p' represents Binary 8 99 | ``` 100 | 101 | Binary mode enabled (true): Combines key presses to calculate the workspace number. 102 | 103 | Binary values (1, 2, 4, 8) determine which binary workspace is triggered. 104 | 105 |

Such surfaces are assigned to a "layer" of the output and 32 | rendered with a defined z-depth respective to each other. They may also be 33 | anchored to the edges and corners of a screen and specify input handling 34 | semantics. This interface should be suitable for the implementation of 35 | many desktop shell components, and a broad number of other applications 36 | that interact with the desktop. 37 | 38 | 39 | 40 | 41 | Create a layer surface for an existing surface. This assigns the role of 42 | layer_surface, or raises a protocol error if another role is already 43 | assigned. 44 | 45 | Creating a layer surface from a wl_surface which has a buffer attached 46 | or committed is a client error, and any attempts by a client to attach 47 | or manipulate a buffer prior to the first layer_surface.configure call 48 | must also be treated as errors. 49 | 50 | After creating a layer_surface object and setting it up, the client 51 | must perform an initial commit without any buffer attached. 52 | The compositor will reply with a layer_surface.configure event. 53 | The client must acknowledge it and is then allowed to attach a buffer 54 | to map the surface. 55 | 56 | You may pass NULL for output to allow the compositor to decide which 57 | output to use. Generally this will be the one that the user most 58 | recently interacted with. 59 | 60 | Clients can specify a namespace that defines the purpose of the layer 61 | surface. 62 | 63 | 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 | 72 | 73 | 74 | 75 | 76 | 77 | 78 | These values indicate which layers a surface can be rendered in. They 79 | are ordered by z depth, bottom-most first. Traditional shell surfaces 80 | will typically be rendered between the bottom and top layers. 81 | Fullscreen shell surfaces are typically rendered at the top layer. 82 | Multiple surfaces can share a single layer, and ordering within a 83 | single layer is undefined. 84 | 85 | 86 | 87 | 88 | 89 | 90 | 91 | 92 | 93 | 94 | 95 | 96 | This request indicates that the client will not use the layer_shell 97 | object any more. Objects that have been created through this instance 98 | are not affected. 99 | 100 | 101 | 102 | 103 | 104 | 105 | An interface that may be implemented by a wl_surface, for surfaces that 106 | are designed to be rendered as a layer of a stacked desktop-like 107 | environment. 108 | 109 | Layer surface state (layer, size, anchor, exclusive zone, 110 | margin, interactivity) is double-buffered, and will be applied at the 111 | time wl_surface.commit of the corresponding wl_surface is called. 112 | 113 | Attaching a null buffer to a layer surface unmaps it. 114 | 115 | Unmapping a layer_surface means that the surface cannot be shown by the 116 | compositor until it is explicitly mapped again. The layer_surface 117 | returns to the state it had right after layer_shell.get_layer_surface. 118 | The client can re-map the surface by performing a commit without any 119 | buffer attached, waiting for a configure event and handling it as usual. 120 | 121 | 122 | 123 | 124 | Sets the size of the surface in surface-local coordinates. The 125 | compositor will display the surface centered with respect to its 126 | anchors. 127 | 128 | If you pass 0 for either value, the compositor will assign it and 129 | inform you of the assignment in the configure event. You must set your 130 | anchor to opposite edges in the dimensions you omit; not doing so is a 131 | protocol error. Both values are 0 by default. 132 | 133 | Size is double-buffered, see wl_surface.commit. 134 | 135 | 136 | 137 | 138 | 139 | 140 | 141 | Requests that the compositor anchor the surface to the specified edges 142 | and corners. If two orthogonal edges are specified (e.g. 'top' and 143 | 'left'), then the anchor point will be the intersection of the edges 144 | (e.g. the top left corner of the output); otherwise the anchor point 145 | will be centered on that edge, or in the center if none is specified. 146 | 147 | Anchor is double-buffered, see wl_surface.commit. 148 | 149 | 150 | 151 | 152 | 153 | 154 | Requests that the compositor avoids occluding an area with other 155 | surfaces. The compositor's use of this information is 156 | implementation-dependent - do not assume that this region will not 157 | actually be occluded. 158 | 159 | A positive value is only meaningful if the surface is anchored to one 160 | edge or an edge and both perpendicular edges. If the surface is not 161 | anchored, anchored to only two perpendicular edges (a corner), anchored 162 | to only two parallel edges or anchored to all edges, a positive value 163 | will be treated the same as zero. 164 | 165 | A positive zone is the distance from the edge in surface-local 166 | coordinates to consider exclusive. 167 | 168 | Surfaces that do not wish to have an exclusive zone may instead specify 169 | how they should interact with surfaces that do. If set to zero, the 170 | surface indicates that it would like to be moved to avoid occluding 171 | surfaces with a positive exclusive zone. If set to -1, the surface 172 | indicates that it would not like to be moved to accommodate for other 173 | surfaces, and the compositor should extend it all the way to the edges 174 | it is anchored to. 175 | 176 | For example, a panel might set its exclusive zone to 10, so that 177 | maximized shell surfaces are not shown on top of it. A notification 178 | might set its exclusive zone to 0, so that it is moved to avoid 179 | occluding the panel, but shell surfaces are shown underneath it. A 180 | wallpaper or lock screen might set their exclusive zone to -1, so that 181 | they stretch below or over the panel. 182 | 183 | The default value is 0. 184 | 185 | Exclusive zone is double-buffered, see wl_surface.commit. 186 | 187 | 188 | 189 | 190 | 191 | 192 | Requests that the surface be placed some distance away from the anchor 193 | point on the output, in surface-local coordinates. Setting this value 194 | for edges you are not anchored to has no effect. 195 | 196 | The exclusive zone includes the margin. 197 | 198 | Margin is double-buffered, see wl_surface.commit. 199 | 200 | 201 | 202 | 203 | 204 | 205 | 206 | 207 | 208 | Types of keyboard interaction possible for layer shell surfaces. The 209 | rationale for this is twofold: (1) some applications are not interested 210 | in keyboard events and not allowing them to be focused can improve the 211 | desktop experience; (2) some applications will want to take exclusive 212 | keyboard focus. 213 | 214 | 215 | 216 | 217 | This value indicates that this surface is not interested in keyboard 218 | events and the compositor should never assign it the keyboard focus. 219 | 220 | This is the default value, set for newly created layer shell surfaces. 221 | 222 | This is useful for e.g. desktop widgets that display information or 223 | only have interaction with non-keyboard input devices. 224 | 225 | 226 | 227 | 228 | Request exclusive keyboard focus if this surface is above the shell surface layer. 229 | 230 | For the top and overlay layers, the seat will always give 231 | exclusive keyboard focus to the top-most layer which has keyboard 232 | interactivity set to exclusive. If this layer contains multiple 233 | surfaces with keyboard interactivity set to exclusive, the compositor 234 | determines the one receiving keyboard events in an implementation- 235 | defined manner. In this case, no guarantee is made when this surface 236 | will receive keyboard focus (if ever). 237 | 238 | For the bottom and background layers, the compositor is allowed to use 239 | normal focus semantics. 240 | 241 | This setting is mainly intended for applications that need to ensure 242 | they receive all keyboard events, such as a lock screen or a password 243 | prompt. 244 | 245 | 246 | 247 | 248 | This requests the compositor to allow this surface to be focused and 249 | unfocused by the user in an implementation-defined manner. The user 250 | should be able to unfocus this surface even regardless of the layer 251 | it is on. 252 | 253 | Typically, the compositor will want to use its normal mechanism to 254 | manage keyboard focus between layer shell surfaces with this setting 255 | and regular toplevels on the desktop layer (e.g. click to focus). 256 | Nevertheless, it is possible for a compositor to require a special 257 | interaction to focus or unfocus layer shell surfaces (e.g. requiring 258 | a click even if focus follows the mouse normally, or providing a 259 | keybinding to switch focus between layers). 260 | 261 | This setting is mainly intended for desktop shell components (e.g. 262 | panels) that allow keyboard interaction. Using this option can allow 263 | implementing a desktop shell that can be fully usable without the 264 | mouse. 265 | 266 | 267 | 268 | 269 | 270 | 271 | Set how keyboard events are delivered to this surface. By default, 272 | layer shell surfaces do not receive keyboard events; this request can 273 | be used to change this. 274 | 275 | This setting is inherited by child surfaces set by the get_popup 276 | request. 277 | 278 | Layer surfaces receive pointer, touch, and tablet events normally. If 279 | you do not want to receive them, set the input region on your surface 280 | to an empty region. 281 | 282 | Keyboard interactivity is double-buffered, see wl_surface.commit. 283 | 284 | 285 | 286 | 287 | 288 | 289 | This assigns an xdg_popup's parent to this layer_surface. This popup 290 | should have been created via xdg_surface::get_popup with the parent set 291 | to NULL, and this request must be invoked before committing the popup's 292 | initial state. 293 | 294 | See the documentation of xdg_popup for more details about what an 295 | xdg_popup is and how it is used. 296 | 297 | 298 | 299 | 300 | 301 | 302 | When a configure event is received, if a client commits the 303 | surface in response to the configure event, then the client 304 | must make an ack_configure request sometime before the commit 305 | request, passing along the serial of the configure event. 306 | 307 | If the client receives multiple configure events before it 308 | can respond to one, it only has to ack the last configure event. 309 | 310 | A client is not required to commit immediately after sending 311 | an ack_configure request - it may even ack_configure several times 312 | before its next surface commit. 313 | 314 | A client may send multiple ack_configure requests before committing, but 315 | only the last request sent before a commit indicates which configure 316 | event the client really is responding to. 317 | 318 | 319 | 320 | 321 | 322 | 323 | This request destroys the layer surface. 324 | 325 | 326 | 327 | 328 | 329 | The configure event asks the client to resize its surface. 330 | 331 | Clients should arrange their surface for the new states, and then send 332 | an ack_configure request with the serial sent in this configure event at 333 | some point before committing the new surface. 334 | 335 | The client is free to dismiss all but the last configure event it 336 | received. 337 | 338 | The width and height arguments specify the size of the window in 339 | surface-local coordinates. 340 | 341 | The size is a hint, in the sense that the client is free to ignore it if 342 | it doesn't resize, pick a smaller size (to satisfy aspect ratio or 343 | resize in steps of NxM pixels). If the client picks a smaller size and 344 | is anchored to two opposite anchors (e.g. 'top' and 'bottom'), the 345 | surface will be centered on this axis. 346 | 347 | If the width or height arguments are zero, it means the client should 348 | decide its own window dimension. 349 | 350 | 351 | 352 | 353 | 354 | 355 | 356 | 357 | The closed event is sent by the compositor when the surface will no 358 | longer be shown. The output may have been destroyed or the user may 359 | have asked for it to be removed. Further changes to the surface will be 360 | ignored. The client should destroy the resource after receiving this 361 | event, and create a new surface if they so choose. 362 | 363 | 364 | 365 | 366 | 367 | 368 | 369 | 370 | 371 | 372 | 373 | 374 | 375 | 376 | 377 | 378 | 379 | 380 | 381 | 382 | 383 | Change the layer that the surface is rendered on. 384 | 385 | Layer is double-buffered, see wl_surface.commit. 386 | 387 | 388 | 389 | 390 | 391 | --------------------------------------------------------------------------------
