By contrast, 26 | the GNU General Public License is intended to guarantee your freedom to 27 | share and change all versions of a program--to make sure it remains free 28 | software for all its users. We, the Free Software Foundation, use the 29 | GNU General Public License for most of our software; it applies also to 30 | any other work released this way by its authors. You can apply it to 31 | your programs, too. 32 | 33 | When we speak of free software, we are referring to freedom, not 34 | price. Our General Public Licenses are designed to make sure that you 35 | have the freedom to distribute copies of free software (and charge for 36 | them if you wish), that you receive source code or can get it if you 37 | want it, that you can change the software or use pieces of it in new 38 | free programs, and that you know you can do these things. 39 | 40 | To protect your rights, we need to prevent others from denying you 41 | these rights or asking you to surrender the rights. Therefore, you have 42 | certain responsibilities if you distribute copies of the software, or if 43 | you modify it: responsibilities to respect the freedom of others. 44 | 45 | For example, if you distribute copies of such a program, whether 46 | gratis or for a fee, you must pass on to the recipients the same 47 | freedoms that you received. You must make sure that they, too, receive 48 | or can get the source code. And you must show them these terms so they 49 | know their rights. 50 | 51 | Developers that use the GNU GPL protect your rights with two steps: 52 | (1) assert copyright on the software, and (2) offer you this License 53 | giving you legal permission to copy, distribute and/or modify it. 54 | 55 | For the developers' and authors' protection, the GPL clearly explains 56 | that there is no warranty for this free software. For both users' and 57 | authors' sake, the GPL requires that modified versions be marked as 58 | changed, so that their problems will not be attributed erroneously to 59 | authors of previous versions. 60 | 61 | Some devices are designed to deny users access to install or run 62 | modified versions of the software inside them, although the manufacturer 63 | can do so. This is fundamentally incompatible with the aim of 64 | protecting users' freedom to change the software. The systematic 65 | pattern of such abuse occurs in the area of products for individuals to 66 | use, which is precisely where it is most unacceptable. Therefore, we 67 | have designed this version of the GPL to prohibit the practice for those 68 | products. If such problems arise substantially in other domains, we 69 | stand ready to extend this provision to those domains in future versions 70 | of the GPL, as needed to protect the freedom of users. 71 | 72 | Finally, every program is threatened constantly by software patents. 73 | States should not allow patents to restrict development and use of 74 | software on general-purpose computers, but in those that do, we wish to 75 | avoid the special danger that patents applied to a free program could 76 | make it effectively proprietary. To prevent this, the GPL assures that 77 | patents cannot be used to render the program non-free. 78 | 79 | The precise terms and conditions for copying, distribution and 80 | modification follow. 81 | 82 | TERMS AND CONDITIONS 83 | 84 | 0. Definitions. 85 | 86 | "This License" refers to version 3 of the GNU General Public License. 87 | 88 | "Copyright" also means copyright-like laws that apply to other kinds of 89 | works, such as semiconductor masks. 90 | 91 | "The Program" refers to any copyrightable work licensed under this 92 | License. Each licensee is addressed as "you". "Licensees" and 93 | "recipients" may be individuals or organizations. 94 | 95 | To "modify" a work means to copy from or adapt all or part of the work 96 | in a fashion requiring copyright permission, other than the making of an 97 | exact copy. The resulting work is called a "modified version" of the 98 | earlier work or a work "based on" the earlier work. 99 | 100 | A "covered work" means either the unmodified Program or a work based 101 | on the Program. 102 | 103 | To "propagate" a work means to do anything with it that, without 104 | permission, would make you directly or secondarily liable for 105 | infringement under applicable copyright law, except executing it on a 106 | computer or modifying a private copy. Propagation includes copying, 107 | distribution (with or without modification), making available to the 108 | public, and in some countries other activities as well. 109 | 110 | To "convey" a work means any kind of propagation that enables other 111 | parties to make or receive copies. Mere interaction with a user through 112 | a computer network, with no transfer of a copy, is not conveying. 113 | 114 | An interactive user interface displays "Appropriate Legal Notices" 115 | to the extent that it includes a convenient and prominently visible 116 | feature that (1) displays an appropriate copyright notice, and (2) 117 | tells the user that there is no warranty for the work (except to the 118 | extent that warranties are provided), that licensees may convey the 119 | work under this License, and how to view a copy of this License. If 120 | the interface presents a list of user commands or options, such as a 121 | menu, a prominent item in the list meets this criterion. 122 | 123 | 1. Source Code. 124 | 125 | The "source code" for a work means the preferred form of the work 126 | for making modifications to it. "Object code" means any non-source 127 | form of a work. 128 | 129 | A "Standard Interface" means an interface that either is an official 130 | standard defined by a recognized standards body, or, in the case of 131 | interfaces specified for a particular programming language, one that 132 | is widely used among developers working in that language. 133 | 134 | The "System Libraries" of an executable work include anything, other 135 | than the work as a whole, that (a) is included in the normal form of 136 | packaging a Major Component, but which is not part of that Major 137 | Component, and (b) serves only to enable use of the work with that 138 | Major Component, or to implement a Standard Interface for which an 139 | implementation is available to the public in source code form. A 140 | "Major Component", in this context, means a major essential component 141 | (kernel, window system, and so on) of the specific operating system 142 | (if any) on which the executable work runs, or a compiler used to 143 | produce the work, or an object code interpreter used to run it. 144 | 145 | The "Corresponding Source" for a work in object code form means all 146 | the source code needed to generate, install, and (for an executable 147 | work) run the object code and to modify the work, including scripts to 148 | control those activities. However, it does not include the work's 149 | System Libraries, or general-purpose tools or generally available free 150 | programs which are used unmodified in performing those activities but 151 | which are not part of the work. For example, Corresponding Source 152 | includes interface definition files associated with source files for 153 | the work, and the source code for shared libraries and dynamically 154 | linked subprograms that the work is specifically designed to require, 155 | such as by intimate data communication or control flow between those 156 | subprograms and other parts of the work. 157 | 158 | The Corresponding Source need not include anything that users 159 | can regenerate automatically from other parts of the Corresponding 160 | Source. 161 | 162 | The Corresponding Source for a work in source code form is that 163 | same work. 164 | 165 | 2. Basic Permissions. 166 | 167 | All rights granted under this License are granted for the term of 168 | copyright on the Program, and are irrevocable provided the stated 169 | conditions are met. This License explicitly affirms your unlimited 170 | permission to run the unmodified Program. The output from running a 171 | covered work is covered by this License only if the output, given its 172 | content, constitutes a covered work. This License acknowledges your 173 | rights of fair use or other equivalent, as provided by copyright law. 174 | 175 | You may make, run and propagate covered works that you do not 176 | convey, without conditions so long as your license otherwise remains 177 | in force. You may convey covered works to others for the sole purpose 178 | of having them make modifications exclusively for you, or provide you 179 | with facilities for running those works, provided that you comply with 180 | the terms of this License in conveying all material for which you do 181 | not control copyright. Those thus making or running the covered works 182 | for you must do so exclusively on your behalf, under your direction 183 | and control, on terms that prohibit them from making any copies of 184 | your copyrighted material outside their relationship with you. 185 | 186 | Conveying under any other circumstances is permitted solely under 187 | the conditions stated below. Sublicensing is not allowed; section 10 188 | makes it unnecessary. 189 | 190 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 191 | 192 | No covered work shall be deemed part of an effective technological 193 | measure under any applicable law fulfilling obligations under article 194 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or 195 | similar laws prohibiting or restricting circumvention of such 196 | measures. 197 | 198 | When you convey a covered work, you waive any legal power to forbid 199 | circumvention of technological measures to the extent such circumvention 200 | is effected by exercising rights under this License with respect to 201 | the covered work, and you disclaim any intention to limit operation or 202 | modification of the work as a means of enforcing, against the work's 203 | users, your or third parties' legal rights to forbid circumvention of 204 | technological measures. 205 | 206 | 4. Conveying Verbatim Copies. 207 | 208 | You may convey verbatim copies of the Program's source code as you 209 | receive it, in any medium, provided that you conspicuously and 210 | appropriately publish on each copy an appropriate copyright notice; 211 | keep intact all notices stating that this License and any 212 | non-permissive terms added in accord with section 7 apply to the code; 213 | keep intact all notices of the absence of any warranty; and give all 214 | recipients a copy of this License along with the Program. 215 | 216 | You may charge any price or no price for each copy that you convey, 217 | and you may offer support or warranty protection for a fee. 218 | 219 | 5. Conveying Modified Source Versions. 220 | 221 | You may convey a work based on the Program, or the modifications to 222 | produce it from the Program, in the form of source code under the 223 | terms of section 4, provided that you also meet all of these conditions: 224 | 225 | a) The work must carry prominent notices stating that you modified 226 | it, and giving a relevant date. 227 | 228 | b) The work must carry prominent notices stating that it is 229 | released under this License and any conditions added under section 230 | 7. This requirement modifies the requirement in section 4 to 231 | "keep intact all notices". 232 | 233 | c) You must license the entire work, as a whole, under this 234 | License to anyone who comes into possession of a copy. This 235 | License will therefore apply, along with any applicable section 7 236 | additional terms, to the whole of the work, and all its parts, 237 | regardless of how they are packaged. This License gives no 238 | permission to license the work in any other way, but it does not 239 | invalidate such permission if you have separately received it. 240 | 241 | d) If the work has interactive user interfaces, each must display 242 | Appropriate Legal Notices; however, if the Program has interactive 243 | interfaces that do not display Appropriate Legal Notices, your 244 | work need not make them do so. 245 | 246 | A compilation of a covered work with other separate and independent 247 | works, which are not by their nature extensions of the covered work, 248 | and which are not combined with it such as to form a larger program, 249 | in or on a volume of a storage or distribution medium, is called an 250 | "aggregate" if the compilation and its resulting copyright are not 251 | used to limit the access or legal rights of the compilation's users 252 | beyond what the individual works permit. Inclusion of a covered work 253 | in an aggregate does not cause this License to apply to the other 254 | parts of the aggregate. 255 | 256 | 6. Conveying Non-Source Forms. 257 | 258 | You may convey a covered work in object code form under the terms 259 | of sections 4 and 5, provided that you also convey the 260 | machine-readable Corresponding Source under the terms of this License, 261 | in one of these ways: 262 | 263 | a) Convey the object code in, or embodied in, a physical product 264 | (including a physical distribution medium), accompanied by the 265 | Corresponding Source fixed on a durable physical medium 266 | customarily used for software interchange. 267 | 268 | b) Convey the object code in, or embodied in, a physical product 269 | (including a physical distribution medium), accompanied by a 270 | written offer, valid for at least three years and valid for as 271 | long as you offer spare parts or customer support for that product 272 | model, to give anyone who possesses the object code either (1) a 273 | copy of the Corresponding Source for all the software in the 274 | product that is covered by this License, on a durable physical 275 | medium customarily used for software interchange, for a price no 276 | more than your reasonable cost of physically performing this 277 | conveying of source, or (2) access to copy the 278 | Corresponding Source from a network server at no charge. 279 | 280 | c) Convey individual copies of the object code with a copy of the 281 | written offer to provide the Corresponding Source. This 282 | alternative is allowed only occasionally and noncommercially, and 283 | only if you received the object code with such an offer, in accord 284 | with subsection 6b. 285 | 286 | d) Convey the object code by offering access from a designated 287 | place (gratis or for a charge), and offer equivalent access to the 288 | Corresponding Source in the same way through the same place at no 289 | further charge. You need not require recipients to copy the 290 | Corresponding Source along with the object code. If the place to 291 | copy the object code is a network server, the Corresponding Source 292 | may be on a different server (operated by you or a third party) 293 | that supports equivalent copying facilities, provided you maintain 294 | clear directions next to the object code saying where to find the 295 | Corresponding Source. Regardless of what server hosts the 296 | Corresponding Source, you remain obligated to ensure that it is 297 | available for as long as needed to satisfy these requirements. 298 | 299 | e) Convey the object code using peer-to-peer transmission, provided 300 | you inform other peers where the object code and Corresponding 301 | Source of the work are being offered to the general public at no 302 | charge under subsection 6d. 303 | 304 | A separable portion of the object code, whose source code is excluded 305 | from the Corresponding Source as a System Library, need not be 306 | included in conveying the object code work. 307 | 308 | A "User Product" is either (1) a "consumer product", which means any 309 | tangible personal property which is normally used for personal, family, 310 | or household purposes, or (2) anything designed or sold for incorporation 311 | into a dwelling. In determining whether a product is a consumer product, 312 | doubtful cases shall be resolved in favor of coverage. For a particular 313 | product received by a particular user, "normally used" refers to a 314 | typical or common use of that class of product, regardless of the status 315 | of the particular user or of the way in which the particular user 316 | actually uses, or expects or is expected to use, the product. A product 317 | is a consumer product regardless of whether the product has substantial 318 | commercial, industrial or non-consumer uses, unless such uses represent 319 | the only significant mode of use of the product. 320 | 321 | "Installation Information" for a User Product means any methods, 322 | procedures, authorization keys, or other information required to install 323 | and execute modified versions of a covered work in that User Product from 324 | a modified version of its Corresponding Source. The information must 325 | suffice to ensure that the continued functioning of the modified object 326 | code is in no case prevented or interfered with solely because 327 | modification has been made. 328 | 329 | If you convey an object code work under this section in, or with, or 330 | specifically for use in, a User Product, and the conveying occurs as 331 | part of a transaction in which the right of possession and use of the 332 | User Product is transferred to the recipient in perpetuity or for a 333 | fixed term (regardless of how the transaction is characterized), the 334 | Corresponding Source conveyed under this section must be accompanied 335 | by the Installation Information. But this requirement does not apply 336 | if neither you nor any third party retains the ability to install 337 | modified object code on the User Product (for example, the work has 338 | been installed in ROM). 339 | 340 | The requirement to provide Installation Information does not include a 341 | requirement to continue to provide support service, warranty, or updates 342 | for a work that has been modified or installed by the recipient, or for 343 | the User Product in which it has been modified or installed. Access to a 344 | network may be denied when the modification itself materially and 345 | adversely affects the operation of the network or violates the rules and 346 | protocols for communication across the network. 347 | 348 | Corresponding Source conveyed, and Installation Information provided, 349 | in accord with this section must be in a format that is publicly 350 | documented (and with an implementation available to the public in 351 | source code form), and must require no special password or key for 352 | unpacking, reading or copying. 353 | 354 | 7. Additional Terms. 355 | 356 | "Additional permissions" are terms that supplement the terms of this 357 | License by making exceptions from one or more of its conditions. 358 | Additional permissions that are applicable to the entire Program shall 359 | be treated as though they were included in this License, to the extent 360 | that they are valid under applicable law. If additional permissions 361 | apply only to part of the Program, that part may be used separately 362 | under those permissions, but the entire Program remains governed by 363 | this License without regard to the additional permissions. 364 | 365 | When you convey a copy of a covered work, you may at your option 366 | remove any additional permissions from that copy, or from any part of 367 | it. (Additional permissions may be written to require their own 368 | removal in certain cases when you modify the work.) You may place 369 | additional permissions on material, added by you to a covered work, 370 | for which you have or can give appropriate copyright permission. 371 | 372 | Notwithstanding any other provision of this License, for material you 373 | add to a covered work, you may (if authorized by the copyright holders of 374 | that material) supplement the terms of this License with terms: 375 | 376 | a) Disclaiming warranty or limiting liability differently from the 377 | terms of sections 15 and 16 of this License; or 378 | 379 | b) Requiring preservation of specified reasonable legal notices or 380 | author attributions in that material or in the Appropriate Legal 381 | Notices displayed by works containing it; or 382 | 383 | c) Prohibiting misrepresentation of the origin of that material, or 384 | requiring that modified versions of such material be marked in 385 | reasonable ways as different from the original version; or 386 | 387 | d) Limiting the use for publicity purposes of names of licensors or 388 | authors of the material; or 389 | 390 | e) Declining to grant rights under trademark law for use of some 391 | trade names, trademarks, or service marks; or 392 | 393 | f) Requiring indemnification of licensors and authors of that 394 | material by anyone who conveys the material (or modified versions of 395 | it) with contractual assumptions of liability to the recipient, for 396 | any liability that these contractual assumptions directly impose on 397 | those licensors and authors. 398 | 399 | All other non-permissive additional terms are considered "further 400 | restrictions" within the meaning of section 10. If the Program as you 401 | received it, or any part of it, contains a notice stating that it is 402 | governed by this License along with a term that is a further 403 | restriction, you may remove that term. If a license document contains 404 | a further restriction but permits relicensing or conveying under this 405 | License, you may add to a covered work material governed by the terms 406 | of that license document, provided that the further restriction does 407 | not survive such relicensing or conveying. 408 | 409 | If you add terms to a covered work in accord with this section, you 410 | must place, in the relevant source files, a statement of the 411 | additional terms that apply to those files, or a notice indicating 412 | where to find the applicable terms. 413 | 414 | Additional terms, permissive or non-permissive, may be stated in the 415 | form of a separately written license, or stated as exceptions; 416 | the above requirements apply either way. 417 | 418 | 8. Termination. 419 | 420 | You may not propagate or modify a covered work except as expressly 421 | provided under this License. Any attempt otherwise to propagate or 422 | modify it is void, and will automatically terminate your rights under 423 | this License (including any patent licenses granted under the third 424 | paragraph of section 11). 425 | 426 | However, if you cease all violation of this License, then your 427 | license from a particular copyright holder is reinstated (a) 428 | provisionally, unless and until the copyright holder explicitly and 429 | finally terminates your license, and (b) permanently, if the copyright 430 | holder fails to notify you of the violation by some reasonable means 431 | prior to 60 days after the cessation. 432 | 433 | Moreover, your license from a particular copyright holder is 434 | reinstated permanently if the copyright holder notifies you of the 435 | violation by some reasonable means, this is the first time you have 436 | received notice of violation of this License (for any work) from that 437 | copyright holder, and you cure the violation prior to 30 days after 438 | your receipt of the notice. 439 | 440 | Termination of your rights under this section does not terminate the 441 | licenses of parties who have received copies or rights from you under 442 | this License. If your rights have been terminated and not permanently 443 | reinstated, you do not qualify to receive new licenses for the same 444 | material under section 10. 445 | 446 | 9. Acceptance Not Required for Having Copies. 447 | 448 | You are not required to accept this License in order to receive or 449 | run a copy of the Program. Ancillary propagation of a covered work 450 | occurring solely as a consequence of using peer-to-peer transmission 451 | to receive a copy likewise does not require acceptance. However, 452 | nothing other than this License grants you permission to propagate or 453 | modify any covered work. These actions infringe copyright if you do 454 | not accept this License. Therefore, by modifying or propagating a 455 | covered work, you indicate your acceptance of this License to do so. 456 | 457 | 10. Automatic Licensing of Downstream Recipients. 458 | 459 | Each time you convey a covered work, the recipient automatically 460 | receives a license from the original licensors, to run, modify and 461 | propagate that work, subject to this License. You are not responsible 462 | for enforcing compliance by third parties with this License. 463 | 464 | An "entity transaction" is a transaction transferring control of an 465 | organization, or substantially all assets of one, or subdividing an 466 | organization, or merging organizations. If propagation of a covered 467 | work results from an entity transaction, each party to that 468 | transaction who receives a copy of the work also receives whatever 469 | licenses to the work the party's predecessor in interest had or could 470 | give under the previous paragraph, plus a right to possession of the 471 | Corresponding Source of the work from the predecessor in interest, if 472 | the predecessor has it or can get it with reasonable efforts. 473 | 474 | You may not impose any further restrictions on the exercise of the 475 | rights granted or affirmed under this License. For example, you may 476 | not impose a license fee, royalty, or other charge for exercise of 477 | rights granted under this License, and you may not initiate litigation 478 | (including a cross-claim or counterclaim in a lawsuit) alleging that 479 | any patent claim is infringed by making, using, selling, offering for 480 | sale, or importing the Program or any portion of it. 481 | 482 | 11. Patents. 483 | 484 | A "contributor" is a copyright holder who authorizes use under this 485 | License of the Program or a work on which the Program is based. The 486 | work thus licensed is called the contributor's "contributor version". 487 | 488 | A contributor's "essential patent claims" are all patent claims 489 | owned or controlled by the contributor, whether already acquired or 490 | hereafter acquired, that would be infringed by some manner, permitted 491 | by this License, of making, using, or selling its contributor version, 492 | but do not include claims that would be infringed only as a 493 | consequence of further modification of the contributor version. For 494 | purposes of this definition, "control" includes the right to grant 495 | patent sublicenses in a manner consistent with the requirements of 496 | this License. 497 | 498 | Each contributor grants you a non-exclusive, worldwide, royalty-free 499 | patent license under the contributor's essential patent claims, to 500 | make, use, sell, offer for sale, import and otherwise run, modify and 501 | propagate the contents of its contributor version. 502 | 503 | In the following three paragraphs, a "patent license" is any express 504 | agreement or commitment, however denominated, not to enforce a patent 505 | (such as an express permission to practice a patent or covenant not to 506 | sue for patent infringement). To "grant" such a patent license to a 507 | party means to make such an agreement or commitment not to enforce a 508 | patent against the party. 509 | 510 | If you convey a covered work, knowingly relying on a patent license, 511 | and the Corresponding Source of the work is not available for anyone 512 | to copy, free of charge and under the terms of this License, through a 513 | publicly available network server or other readily accessible means, 514 | then you must either (1) cause the Corresponding Source to be so 515 | available, or (2) arrange to deprive yourself of the benefit of the 516 | patent license for this particular work, or (3) arrange, in a manner 517 | consistent with the requirements of this License, to extend the patent 518 | license to downstream recipients. "Knowingly relying" means you have 519 | actual knowledge that, but for the patent license, your conveying the 520 | covered work in a country, or your recipient's use of the covered work 521 | in a country, would infringe one or more identifiable patents in that 522 | country that you have reason to believe are valid. 523 | 524 | If, pursuant to or in connection with a single transaction or 525 | arrangement, you convey, or propagate by procuring conveyance of, a 526 | covered work, and grant a patent license to some of the parties 527 | receiving the covered work authorizing them to use, propagate, modify 528 | or convey a specific copy of the covered work, then the patent license 529 | you grant is automatically extended to all recipients of the covered 530 | work and works based on it. 531 | 532 | A patent license is "discriminatory" if it does not include within 533 | the scope of its coverage, prohibits the exercise of, or is 534 | conditioned on the non-exercise of one or more of the rights that are 535 | specifically granted under this License. You may not convey a covered 536 | work if you are a party to an arrangement with a third party that is 537 | in the business of distributing software, under which you make payment 538 | to the third party based on the extent of your activity of conveying 539 | the work, and under which the third party grants, to any of the 540 | parties who would receive the covered work from you, a discriminatory 541 | patent license (a) in connection with copies of the covered work 542 | conveyed by you (or copies made from those copies), or (b) primarily 543 | for and in connection with specific products or compilations that 544 | contain the covered work, unless you entered into that arrangement, 545 | or that patent license was granted, prior to 28 March 2007. 546 | 547 | Nothing in this License shall be construed as excluding or limiting 548 | any implied license or other defenses to infringement that may 549 | otherwise be available to you under applicable patent law. 550 | 551 | 12. No Surrender of Others' Freedom. 552 | 553 | If conditions are imposed on you (whether by court order, agreement or 554 | otherwise) that contradict the conditions of this License, they do not 555 | excuse you from the conditions of this License. If you cannot convey a 556 | covered work so as to satisfy simultaneously your obligations under this 557 | License and any other pertinent obligations, then as a consequence you may 558 | not convey it at all. For example, if you agree to terms that obligate you 559 | to collect a royalty for further conveying from those to whom you convey 560 | the Program, the only way you could satisfy both those terms and this 561 | License would be to refrain entirely from conveying the Program. 562 | 563 | 13. Use with the GNU Affero General Public License. 564 | 565 | Notwithstanding any other provision of this License, you have 566 | permission to link or combine any covered work with a work licensed 567 | under version 3 of the GNU Affero General Public License into a single 568 | combined work, and to convey the resulting work. The terms of this 569 | License will continue to apply to the part which is the covered work, 570 | but the special requirements of the GNU Affero General Public License, 571 | section 13, concerning interaction through a network will apply to the 572 | combination as such. 573 | 574 | 14. Revised Versions of this License. 575 | 576 | The Free Software Foundation may publish revised and/or new versions of 577 | the GNU General Public License from time to time. Such new versions will 578 | be similar in spirit to the present version, but may differ in detail to 579 | address new problems or concerns. 580 | 581 | Each version is given a distinguishing version number. If the 582 | Program specifies that a certain numbered version of the GNU General 583 | Public License "or any later version" applies to it, you have the 584 | option of following the terms and conditions either of that numbered 585 | version or of any later version published by the Free Software 586 | Foundation. If the Program does not specify a version number of the 587 | GNU General Public License, you may choose any version ever published 588 | by the Free Software Foundation. 589 | 590 | If the Program specifies that a proxy can decide which future 591 | versions of the GNU General Public License can be used, that proxy's 592 | public statement of acceptance of a version permanently authorizes you 593 | to choose that version for the Program. 594 | 595 | Later license versions may give you additional or different 596 | permissions. However, no additional obligations are imposed on any 597 | author or copyright holder as a result of your choosing to follow a 598 | later version. 599 | 600 | 15. Disclaimer of Warranty. 601 | 602 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 603 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 604 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 605 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 606 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 607 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 608 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 609 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 610 | 611 | 16. Limitation of Liability. 612 | 613 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 614 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 615 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 616 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 617 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 618 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 619 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 620 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 621 | SUCH DAMAGES. 622 | 623 | 17. Interpretation of Sections 15 and 16. 624 | 625 | If the disclaimer of warranty and limitation of liability provided 626 | above cannot be given local legal effect according to their terms, 627 | reviewing courts shall apply local law that most closely approximates 628 | an absolute waiver of all civil liability in connection with the 629 | Program, unless a warranty or assumption of liability accompanies a 630 | copy of the Program in return for a fee. 631 | -------------------------------------------------------------------------------- /Makefile: -------------------------------------------------------------------------------- 1 | PREFIX?=/usr 2 | BINDIR=$(PREFIX)/bin 3 | 4 | install: 5 | mkdir -p $(BINDIR) 6 | install -m755 floating-terminal $(BINDIR)/floating-terminal 7 | install -m755 term-dmenu $(BINDIR)/term-dmenu 8 | install -m755 dmenu-runner $(BINDIR)/dmenu-runner 9 | install -m755 app-launcher $(BINDIR)/app-launcher 10 | install -m755 window-switcher $(BINDIR)/window-switcher 11 | uninstall: 12 | rm -rf $(BINDIR)/floating-terminal 13 | rm -rf $(BINDIR)/term-dmenu 14 | rm -rf $(BINDIR)/dmenu-runner 15 | rm -rf $(BINDIR)/app-launcher 16 | rm -rf $(BINDIR)/window-switcher 17 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | term-dmenu 2 | ========== 3 | 4 | [![sourcehut]](https://git.sr.ht/~seirdy/term-dmenu) 5 | [![GitLab 6 | mirror](https://img.shields.io/badge/mirror-GitLab-orange.svg?logo=gitlab)](https://gitlab.com/Seirdy/term-dmenu) 7 | [![GitHub 8 | mirror](https://img.shields.io/badge/mirror-GitHub-black.svg?logo=github)](https://github.com/Seirdy/term-dmenu) 9 | 10 | A replacement for Rofi, dmenu, and other launchers that uses FZF and a plain-old 11 | terminal emulator. 12 | 13 | I recommend altering these scripts to suit your preferences. 14 | 15 | What's inside 16 | ------------- 17 | 18 | The main script is `term-dmenu` and its dependency `floating-terminal`. `term-dmenu` 19 | is a dmenu replacement that turns stdin into an interactive menu and sends output 20 | back to stdout. In other words, if you don't use any of dmenu's CLI options, you can 21 | probably just `alias dmenu=term-dmenu` and you'll be just fine. 22 | 23 | Helper scripts work with `term-dmenu`. If you set the environment variable 24 | `$DMENU_PROGRAM` to something else (e.g. `dmenu` or `rofi -dmenu`), the helper 25 | scripts will use those programs instead. 26 | 27 | - `dmenu-runner` can run any executable in your `$PATH`. Because of the large number 28 | of executables on most systems, recent entries are saved and prioritized to make 29 | searching easier. 30 | - `app-launcher` launches desktop applications using `j4-dmenu-desktop` 31 | - `window-switcher` allows listing/filtering/selecting open windows in Sway or i3 32 | (much like what Alt+TAB does on most desktop environments). 33 | 34 | Dependencies 35 | ------------ 36 | 37 | - FZF 38 | - `j4-dmenu-desktop` for `app-launcher` 39 | - `window-switcher` requires Sway or i3 to be running 40 | 41 | Configuration 42 | ------------- 43 | 44 | If you don't want to use `term-dmenu` but would like to use some of the helper 45 | scripts 46 | 47 | Differences from similar implementations 48 | ---------------------------------------- 49 | 50 | Other projects attempting to replace dmenu/rofi with terminal emulators exist, most 51 | notably [sway-launcher-desktop](https://github.com/Biont/sway-launcher-desktop). I 52 | created my own project instead of contributing upstream because I had different 53 | goals: 54 | 55 | - Modularity: split dmenu functionality into `term-dmenu`, and make helper scripts 56 | work with dmenu, rofi, and term-dmenu equally well. 57 | - 100% POSIX shell compatibility; no bashisms. Running these scripts with `dash` 58 | (the Debian Almquist shell) should yield faster startup speed. 59 | - `app-launcher` uses `j4-dmenu-desktop` to find .desktop files, which is better 60 | than using shell/AWK expressions. 61 | - `floating-terminal` launches the terminal. If the environment variable 62 | `$FLOATING_TERMINAL` is unset, it runs the first of the following programs that is 63 | found in `$PATH`: 64 | 1. `havoc $@` 65 | 2. `alacritty --class=launcher -e $@` 66 | 3. `kitty --class=launcher -e $@` 67 | 4. `konsole -e $@` 68 | 5. `gnome-terminal -e $@` 69 | 6. `termite -e $@` 70 | 7. `st -c launcher -e $@` 71 | 8. `xterm -e $@` 72 | 73 | Acknowledgements 74 | ---------------- 75 | 76 | `dmenu-runner` code is based on [this 77 | script](https://gitlab.com/FlyingWombat/my-scripts/blob/a0cb5717777c1587af381004aa8fb048206bee55/sway-launcher) 78 | by FlyingWombat ([Wayback 79 | Machine](https://web.archive.org/web/20200209122744/https://gitlab.com/FlyingWombat/my-scripts/blob/a0cb5717777c1587af381004aa8fb048206bee55/sway-launcher), 80 | [archive.today](https://archive.today/yHFrW)), with inspiration from 81 | [`dmenu_run_history`](https://tools.suckless.org/dmenu/scripts/dmenu_run_with_command_history/). 82 | 83 | Many bits of code were borrowed from the discussion in [issue 84 | 1367](https://github.com/swaywm/sway/issues/1367) of Sway's GitHub issue tracker. 85 | 86 | [sourcehut]: https://img.shields.io/badge/repository-sourcehut-lightgrey.svg?logo=data:image/svg+xml;base64,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 87 | -------------------------------------------------------------------------------- /app-launcher: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | 3 | # set your preferred dmenu-like program in the environment variable $DMENU_PROGRAM 4 | # examples: "dmenu", "rofi -dmenu", "term-dmenu", or just "fzf" to run in your current terminal 5 | [ -z "$DMENU_PROGRAM" ] && DMENU_PROGRAM='term-dmenu --no-extended --print-query' 6 | 7 | # launcher for .desktop files; used with app-runner script 8 | # shellcheck disable=SC2154 9 | if [ -n "$TERMINAL" ]; then 10 | j4-dmenu-desktop --term="$TERMINAL" --dmenu="$DMENU_PROGRAM" 11 | else 12 | j4-dmenu-desktop --dmenu="$DMENU_PROGRAM" 13 | fi 14 | 15 | # vi:ft=sh 16 | -------------------------------------------------------------------------------- /dmenu-runner: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | 3 | # POSIX-compliant (bashism-free) shell script to use a dmenu-like program 4 | # to select/run executables found in $PATH, saving and prioritizing previous 5 | # commands.
