IN NO EVENT SHALL THE 19 | AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER 20 | LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, 21 | OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN 22 | THE SOFTWARE. 23 | 24 | GPLv3 License 25 | -------------- 26 | 27 | GNU GENERAL PUBLIC LICENSE 28 | Version 3, 29 June 2007 29 | 30 | Copyright (C) 2007 Free Software Foundation, Inc. 31 | Everyone is permitted to copy and distribute verbatim copies 32 | of this license document, but changing it is not allowed. 33 | 34 | Preamble 35 | 36 | The GNU General Public License is a free, copyleft license for 37 | software and other kinds of works. 38 | 39 | The licenses for most software and other practical works are designed 40 | to take away your freedom to share and change the works. By contrast, 41 | the GNU General Public License is intended to guarantee your freedom to 42 | share and change all versions of a program--to make sure it remains free 43 | software for all its users. We, the Free Software Foundation, use the 44 | GNU General Public License for most of our software; it applies also to 45 | any other work released this way by its authors. You can apply it to 46 | your programs, too. 47 | 48 | When we speak of free software, we are referring to freedom, not 49 | price. Our General Public Licenses are designed to make sure that you 50 | have the freedom to distribute copies of free software (and charge for 51 | them if you wish), that you receive source code or can get it if you 52 | want it, that you can change the software or use pieces of it in new 53 | free programs, and that you know you can do these things. 54 | 55 | To protect your rights, we need to prevent others from denying you 56 | these rights or asking you to surrender the rights. Therefore, you have 57 | certain responsibilities if you distribute copies of the software, or if 58 | you modify it: responsibilities to respect the freedom of others. 59 | 60 | For example, if you distribute copies of such a program, whether 61 | gratis or for a fee, you must pass on to the recipients the same 62 | freedoms that you received. You must make sure that they, too, receive 63 | or can get the source code. And you must show them these terms so they 64 | know their rights. 65 | 66 | Developers that use the GNU GPL protect your rights with two steps: 67 | (1) assert copyright on the software, and (2) offer you this License 68 | giving you legal permission to copy, distribute and/or modify it. 69 | 70 | For the developers' and authors' protection, the GPL clearly explains 71 | that there is no warranty for this free software. For both users' and 72 | authors' sake, the GPL requires that modified versions be marked as 73 | changed, so that their problems will not be attributed erroneously to 74 | authors of previous versions. 75 | 76 | Some devices are designed to deny users access to install or run 77 | modified versions of the software inside them, although the manufacturer 78 | can do so. This is fundamentally incompatible with the aim of 79 | protecting users' freedom to change the software. The systematic 80 | pattern of such abuse occurs in the area of products for individuals to 81 | use, which is precisely where it is most unacceptable. Therefore, we 82 | have designed this version of the GPL to prohibit the practice for those 83 | products. If such problems arise substantially in other domains, we 84 | stand ready to extend this provision to those domains in future versions 85 | of the GPL, as needed to protect the freedom of users. 86 | 87 | Finally, every program is threatened constantly by software patents. 88 | States should not allow patents to restrict development and use of 89 | software on general-purpose computers, but in those that do, we wish to 90 | avoid the special danger that patents applied to a free program could 91 | make it effectively proprietary. To prevent this, the GPL assures that 92 | patents cannot be used to render the program non-free. 93 | 94 | The precise terms and conditions for copying, distribution and 95 | modification follow. 96 | 97 | TERMS AND CONDITIONS 98 | 99 | 0. Definitions. 100 | 101 | "This License" refers to version 3 of the GNU General Public License. 102 | 103 | "Copyright" also means copyright-like laws that apply to other kinds of 104 | works, such as semiconductor masks. 105 | 106 | "The Program" refers to any copyrightable work licensed under this 107 | License. Each licensee is addressed as "you". "Licensees" and 108 | "recipients" may be individuals or organizations. 109 | 110 | To "modify" a work means to copy from or adapt all or part of the work 111 | in a fashion requiring copyright permission, other than the making of an 112 | exact copy. The resulting work is called a "modified version" of the 113 | earlier work or a work "based on" the earlier work. 114 | 115 | A "covered work" means either the unmodified Program or a work based 116 | on the Program. 117 | 118 | To "propagate" a work means to do anything with it that, without 119 | permission, would make you directly or secondarily liable for 120 | infringement under applicable copyright law, except executing it on a 121 | computer or modifying a private copy. Propagation includes copying, 122 | distribution (with or without modification), making available to the 123 | public, and in some countries other activities as well. 124 | 125 | To "convey" a work means any kind of propagation that enables other 126 | parties to make or receive copies. Mere interaction with a user through 127 | a computer network, with no transfer of a copy, is not conveying. 128 | 129 | An interactive user interface displays "Appropriate Legal Notices" 130 | to the extent that it includes a convenient and prominently visible 131 | feature that (1) displays an appropriate copyright notice, and (2) 132 | tells the user that there is no warranty for the work (except to the 133 | extent that warranties are provided), that licensees may convey the 134 | work under this License, and how to view a copy of this License. If 135 | the interface presents a list of user commands or options, such as a 136 | menu, a prominent item in the list meets this criterion. 137 | 138 | 1. Source Code. 139 | 140 | The "source code" for a work means the preferred form of the work 141 | for making modifications to it. "Object code" means any non-source 142 | form of a work. 143 | 144 | A "Standard Interface" means an interface that either is an official 145 | standard defined by a recognized standards body, or, in the case of 146 | interfaces specified for a particular programming language, one that 147 | is widely used among developers working in that language. 148 | 149 | The "System Libraries" of an executable work include anything, other 150 | than the work as a whole, that (a) is included in the normal form of 151 | packaging a Major Component, but which is not part of that Major 152 | Component, and (b) serves only to enable use of the work with that 153 | Major Component, or to implement a Standard Interface for which an 154 | implementation is available to the public in source code form. A 155 | "Major Component", in this context, means a major essential component 156 | (kernel, window system, and so on) of the specific operating system 157 | (if any) on which the executable work runs, or a compiler used to 158 | produce the work, or an object code interpreter used to run it. 159 | 160 | The "Corresponding Source" for a work in object code form means all 161 | the source code needed to generate, install, and (for an executable 162 | work) run the object code and to modify the work, including scripts to 163 | control those activities. However, it does not include the work's 164 | System Libraries, or general-purpose tools or generally available free 165 | programs which are used unmodified in performing those activities but 166 | which are not part of the work. For example, Corresponding Source 167 | includes interface definition files associated with source files for 168 | the work, and the source code for shared libraries and dynamically 169 | linked subprograms that the work is specifically designed to require, 170 | such as by intimate data communication or control flow between those 171 | subprograms and other parts of the work. 172 | 173 | The Corresponding Source need not include anything that users 174 | can regenerate automatically from other parts of the Corresponding 175 | Source. 176 | 177 | The Corresponding Source for a work in source code form is that 178 | same work. 179 | 180 | 2. Basic Permissions. 181 | 182 | All rights granted under this License are granted for the term of 183 | copyright on the Program, and are irrevocable provided the stated 184 | conditions are met. This License explicitly affirms your unlimited 185 | permission to run the unmodified Program. The output from running a 186 | covered work is covered by this License only if the output, given its 187 | content, constitutes a covered work. This License acknowledges your 188 | rights of fair use or other equivalent, as provided by copyright law. 189 | 190 | You may make, run and propagate covered works that you do not 191 | convey, without conditions so long as your license otherwise remains 192 | in force. You may convey covered works to others for the sole purpose 193 | of having them make modifications exclusively for you, or provide you 194 | with facilities for running those works, provided that you comply with 195 | the terms of this License in conveying all material for which you do 196 | not control copyright. Those thus making or running the covered works 197 | for you must do so exclusively on your behalf, under your direction 198 | and control, on terms that prohibit them from making any copies of 199 | your copyrighted material outside their relationship with you. 200 | 201 | Conveying under any other circumstances is permitted solely under 202 | the conditions stated below. Sublicensing is not allowed; section 10 203 | makes it unnecessary. 204 | 205 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 206 | 207 | No covered work shall be deemed part of an effective technological 208 | measure under any applicable law fulfilling obligations under article 209 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or 210 | similar laws prohibiting or restricting circumvention of such 211 | measures. 212 | 213 | When you convey a covered work, you waive any legal power to forbid 214 | circumvention of technological measures to the extent such circumvention 215 | is effected by exercising rights under this License with respect to 216 | the covered work, and you disclaim any intention to limit operation or 217 | modification of the work as a means of enforcing, against the work's 218 | users, your or third parties' legal rights to forbid circumvention of 219 | technological measures. 220 | 221 | 4. Conveying Verbatim Copies. 222 | 223 | You may convey verbatim copies of the Program's source code as you 224 | receive it, in any medium, provided that you conspicuously and 225 | appropriately publish on each copy an appropriate copyright notice; 226 | keep intact all notices stating that this License and any 227 | non-permissive terms added in accord with section 7 apply to the code; 228 | keep intact all notices of the absence of any warranty; and give all 229 | recipients a copy of this License along with the Program. 230 | 231 | You may charge any price or no price for each copy that you convey, 232 | and you may offer support or warranty protection for a fee. 233 | 234 | 5. Conveying Modified Source Versions. 235 | 236 | You may convey a work based on the Program, or the modifications to 237 | produce it from the Program, in the form of source code under the 238 | terms of section 4, provided that you also meet all of these conditions: 239 | 240 | a) The work must carry prominent notices stating that you modified 241 | it, and giving a relevant date. 242 | 243 | b) The work must carry prominent notices stating that it is 244 | released under this License and any conditions added under section 245 | 7. This requirement modifies the requirement in section 4 to 246 | "keep intact all notices". 247 | 248 | c) You must license the entire work, as a whole, under this 249 | License to anyone who comes into possession of a copy. This 250 | License will therefore apply, along with any applicable section 7 251 | additional terms, to the whole of the work, and all its parts, 252 | regardless of how they are packaged. This License gives no 253 | permission to license the work in any other way, but it does not 254 | invalidate such permission if you have separately received it. 255 | 256 | d) If the work has interactive user interfaces, each must display 257 | Appropriate Legal Notices; however, if the Program has interactive 258 | interfaces that do not display Appropriate Legal Notices, your 259 | work need not make them do so. 260 | 261 | A compilation of a covered work with other separate and independent 262 | works, which are not by their nature extensions of the covered work, 263 | and which are not combined with it such as to form a larger program, 264 | in or on a volume of a storage or distribution medium, is called an 265 | "aggregate" if the compilation and its resulting copyright are not 266 | used to limit the access or legal rights of the compilation's users 267 | beyond what the individual works permit. Inclusion of a covered work 268 | in an aggregate does not cause this License to apply to the other 269 | parts of the aggregate. 270 | 271 | 6. Conveying Non-Source Forms. 272 | 273 | You may convey a covered work in object code form under the terms 274 | of sections 4 and 5, provided that you also convey the 275 | machine-readable Corresponding Source under the terms of this License, 276 | in one of these ways: 277 | 278 | a) Convey the object code in, or embodied in, a physical product 279 | (including a physical distribution medium), accompanied by the 280 | Corresponding Source fixed on a durable physical medium 281 | customarily used for software interchange. 282 | 283 | b) Convey the object code in, or embodied in, a physical product 284 | (including a physical distribution medium), accompanied by a 285 | written offer, valid for at least three years and valid for as 286 | long as you offer spare parts or customer support for that product 287 | model, to give anyone who possesses the object code either (1) a 288 | copy of the Corresponding Source for all the software in the 289 | product that is covered by this License, on a durable physical 290 | medium customarily used for software interchange, for a price no 291 | more than your reasonable cost of physically performing this 292 | conveying of source, or (2) access to copy the 293 | Corresponding Source from a network server at no charge. 294 | 295 | c) Convey individual copies of the object code with a copy of the 296 | written offer to provide the Corresponding Source. This 297 | alternative is allowed only occasionally and noncommercially, and 298 | only if you received the object code with such an offer, in accord 299 | with subsection 6b. 300 | 301 | d) Convey the object code by offering access from a designated 302 | place (gratis or for a charge), and offer equivalent access to the 303 | Corresponding Source in the same way through the same place at no 304 | further charge. You need not require recipients to copy the 305 | Corresponding Source along with the object code. If the place to 306 | copy the object code is a network server, the Corresponding Source 307 | may be on a different server (operated by you or a third party) 308 | that supports equivalent copying facilities, provided you maintain 309 | clear directions next to the object code saying where to find the 310 | Corresponding Source. Regardless of what server hosts the 311 | Corresponding Source, you remain obligated to ensure that it is 312 | available for as long as needed to satisfy these requirements. 313 | 314 | e) Convey the object code using peer-to-peer transmission, provided 315 | you inform other peers where the object code and Corresponding 316 | Source of the work are being offered to the general public at no 317 | charge under subsection 6d. 318 | 319 | A separable portion of the object code, whose source code is excluded 320 | from the Corresponding Source as a System Library, need not be 321 | included in conveying the object code work. 322 | 323 | A "User Product" is either (1) a "consumer product", which means any 324 | tangible personal property which is normally used for personal, family, 325 | or household purposes, or (2) anything designed or sold for incorporation 326 | into a dwelling. In determining whether a product is a consumer product, 327 | doubtful cases shall be resolved in favor of coverage. For a particular 328 | product received by a particular user, "normally used" refers to a 329 | typical or common use of that class of product, regardless of the status 330 | of the particular user or of the way in which the particular user 331 | actually uses, or expects or is expected to use, the product. A product 332 | is a consumer product regardless of whether the product has substantial 333 | commercial, industrial or non-consumer uses, unless such uses represent 334 | the only significant mode of use of the product. 335 | 336 | "Installation Information" for a User Product means any methods, 337 | procedures, authorization keys, or other information required to install 338 | and execute modified versions of a covered work in that User Product from 339 | a modified version of its Corresponding Source. The information must 340 | suffice to ensure that the continued functioning of the modified object 341 | code is in no case prevented or interfered with solely because 342 | modification has been made. 343 | 344 | If you convey an object code work under this section in, or with, or 345 | specifically for use in, a User Product, and the conveying occurs as 346 | part of a transaction in which the right of possession and use of the 347 | User Product is transferred to the recipient in perpetuity or for a 348 | fixed term (regardless of how the transaction is characterized), the 349 | Corresponding Source conveyed under this section must be accompanied 350 | by the Installation Information. But this requirement does not apply 351 | if neither you nor any third party retains the ability to install 352 | modified object code on the User Product (for example, the work has 353 | been installed in ROM). 354 | 355 | The requirement to provide Installation Information does not include a 356 | requirement to continue to provide support service, warranty, or updates 357 | for a work that has been modified or installed by the recipient, or for 358 | the User Product in which it has been modified or installed. Access to a 359 | network may be denied when the modification itself materially and 360 | adversely affects the operation of the network or violates the rules and 361 | protocols for communication across the network. 362 | 363 | Corresponding Source conveyed, and Installation Information provided, 364 | in accord with this section must be in a format that is publicly 365 | documented (and with an implementation available to the public in 366 | source code form), and must require no special password or key for 367 | unpacking, reading or copying. 368 | 369 | 7. Additional Terms. 370 | 371 | "Additional permissions" are terms that supplement the terms of this 372 | License by making exceptions from one or more of its conditions. 373 | Additional permissions that are applicable to the entire Program shall 374 | be treated as though they were included in this License, to the extent 375 | that they are valid under applicable law. If additional permissions 376 | apply only to part of the Program, that part may be used separately 377 | under those permissions, but the entire Program remains governed by 378 | this License without regard to the additional permissions. 379 | 380 | When you convey a copy of a covered work, you may at your option 381 | remove any additional permissions from that copy, or from any part of 382 | it. (Additional permissions may be written to require their own 383 | removal in certain cases when you modify the work.) You may place 384 | additional permissions on material, added by you to a covered work, 385 | for which you have or can give appropriate copyright permission. 386 | 387 | Notwithstanding any other provision of this License, for material you 388 | add to a covered work, you may (if authorized by the copyright holders of 389 | that material) supplement the terms of this License with terms: 390 | 391 | a) Disclaiming warranty or limiting liability differently from the 392 | terms of sections 15 and 16 of this License; or 393 | 394 | b) Requiring preservation of specified reasonable legal notices or 395 | author attributions in that material or in the Appropriate Legal 396 | Notices displayed by works containing it; or 397 | 398 | c) Prohibiting misrepresentation of the origin of that material, or 399 | requiring that modified versions of such material be marked in 400 | reasonable ways as different from the original version; or 401 | 402 | d) Limiting the use for publicity purposes of names of licensors or 403 | authors of the material; or 404 | 405 | e) Declining to grant rights under trademark law for use of some 406 | trade names, trademarks, or service marks; or 407 | 408 | f) Requiring indemnification of licensors and authors of that 409 | material by anyone who conveys the material (or modified versions of 410 | it) with contractual assumptions of liability to the recipient, for 411 | any liability that these contractual assumptions directly impose on 412 | those licensors and authors. 413 | 414 | All other non-permissive additional terms are considered "further 415 | restrictions" within the meaning of section 10. If the Program as you 416 | received it, or any part of it, contains a notice stating that it is 417 | governed by this License along with a term that is a further 418 | restriction, you may remove that term. If a license document contains 419 | a further restriction but permits relicensing or conveying under this 420 | License, you may add to a covered work material governed by the terms 421 | of that license document, provided that the further restriction does 422 | not survive such relicensing or conveying. 423 | 424 | If you add terms to a covered work in accord with this section, you 425 | must place, in the relevant source files, a statement of the 426 | additional terms that apply to those files, or a notice indicating 427 | where to find the applicable terms. 428 | 429 | Additional terms, permissive or non-permissive, may be stated in the 430 | form of a separately written license, or stated as exceptions; 431 | the above requirements apply either way. 432 | 433 | 8. Termination. 434 | 435 | You may not propagate or modify a covered work except as expressly 436 | provided under this License. Any attempt otherwise to propagate or 437 | modify it is void, and will automatically terminate your rights under 438 | this License (including any patent licenses granted under the third 439 | paragraph of section 11). 440 | 441 | However, if you cease all violation of this License, then your 442 | license from a particular copyright holder is reinstated (a) 443 | provisionally, unless and until the copyright holder explicitly and 444 | finally terminates your license, and (b) permanently, if the copyright 445 | holder fails to notify you of the violation by some reasonable means 446 | prior to 60 days after the cessation. 447 | 448 | Moreover, your license from a particular copyright holder is 449 | reinstated permanently if the copyright holder notifies you of the 450 | violation by some reasonable means, this is the first time you have 451 | received notice of violation of this License (for any work) from that 452 | copyright holder, and you cure the violation prior to 30 days after 453 | your receipt of the notice. 454 | 455 | Termination of your rights under this section does not terminate the 456 | licenses of parties who have received copies or rights from you under 457 | this License. If your rights have been terminated and not permanently 458 | reinstated, you do not qualify to receive new licenses for the same 459 | material under section 10. 460 | 461 | 9. Acceptance Not Required for Having Copies. 462 | 463 | You are not required to accept this License in order to receive or 464 | run a copy of the Program. Ancillary propagation of a covered work 465 | occurring solely as a consequence of using peer-to-peer transmission 466 | to receive a copy likewise does not require acceptance. However, 467 | nothing other than this License grants you permission to propagate or 468 | modify any covered work. These actions infringe copyright if you do 469 | not accept this License. Therefore, by modifying or propagating a 470 | covered work, you indicate your acceptance of this License to do so. 471 | 472 | 10. Automatic Licensing of Downstream Recipients. 473 | 474 | Each time you convey a covered work, the recipient automatically 475 | receives a license from the original licensors, to run, modify and 476 | propagate that work, subject to this License. You are not responsible 477 | for enforcing compliance by third parties with this License. 478 | 479 | An "entity transaction" is a transaction transferring control of an 480 | organization, or substantially all assets of one, or subdividing an 481 | organization, or merging organizations. If propagation of a covered 482 | work results from an entity transaction, each party to that 483 | transaction who receives a copy of the work also receives whatever 484 | licenses to the work the party's predecessor in interest had or could 485 | give under the previous paragraph, plus a right to possession of the 486 | Corresponding Source of the work from the predecessor in interest, if 487 | the predecessor has it or can get it with reasonable efforts. 488 | 489 | You may not impose any further restrictions on the exercise of the 490 | rights granted or affirmed under this License. For example, you may 491 | not impose a license fee, royalty, or other charge for exercise of 492 | rights granted under this License, and you may not initiate litigation 493 | (including a cross-claim or counterclaim in a lawsuit) alleging that 494 | any patent claim is infringed by making, using, selling, offering for 495 | sale, or importing the Program or any portion of it. 496 | 497 | 11. Patents. 498 | 499 | A "contributor" is a copyright holder who authorizes use under this 500 | License of the Program or a work on which the Program is based. The 501 | work thus licensed is called the contributor's "contributor version". 502 | 503 | A contributor's "essential patent claims" are all patent claims 504 | owned or controlled by the contributor, whether already acquired or 505 | hereafter acquired, that would be infringed by some manner, permitted 506 | by this License, of making, using, or selling its contributor version, 507 | but do not include claims that would be infringed only as a 508 | consequence of further modification of the contributor version. For 509 | purposes of this definition, "control" includes the right to grant 510 | patent sublicenses in a manner consistent with the requirements of 511 | this License. 512 | 513 | Each contributor grants you a non-exclusive, worldwide, royalty-free 514 | patent license under the contributor's essential patent claims, to 515 | make, use, sell, offer for sale, import and otherwise run, modify and 516 | propagate the contents of its contributor version. 517 | 518 | In the following three paragraphs, a "patent license" is any express 519 | agreement or commitment, however denominated, not to enforce a patent 520 | (such as an express permission to practice a patent or covenant not to 521 | sue for patent infringement). To "grant" such a patent license to a 522 | party means to make such an agreement or commitment not to enforce a 523 | patent against the party. 524 | 525 | If you convey a covered work, knowingly relying on a patent license, 526 | and the Corresponding Source of the work is not available for anyone 527 | to copy, free of charge and under the terms of this License, through a 528 | publicly available network server or other readily accessible means, 529 | then you must either (1) cause the Corresponding Source to be so 530 | available, or (2) arrange to deprive yourself of the benefit of the 531 | patent license for this particular work, or (3) arrange, in a manner 532 | consistent with the requirements of this License, to extend the patent 533 | license to downstream recipients. "Knowingly relying" means you have 534 | actual knowledge that, but for the patent license, your conveying the 535 | covered work in a country, or your recipient's use of the covered work 536 | in a country, would infringe one or more identifiable patents in that 537 | country that you have reason to believe are valid. 538 | 539 | If, pursuant to or in connection with a single transaction or 540 | arrangement, you convey, or propagate by procuring conveyance of, a 541 | covered work, and grant a patent license to some of the parties 542 | receiving the covered work authorizing them to use, propagate, modify 543 | or convey a specific copy of the covered work, then the patent license 544 | you grant is automatically extended to all recipients of the covered 545 | work and works based on it. 546 | 547 | A patent license is "discriminatory" if it does not include within 548 | the scope of its coverage, prohibits the exercise of, or is 549 | conditioned on the non-exercise of one or more of the rights that are 550 | specifically granted under this License. You may not convey a covered 551 | work if you are a party to an arrangement with a third party that is 552 | in the business of distributing software, under which you make payment 553 | to the third party based on the extent of your activity of conveying 554 | the work, and under which the third party grants, to any of the 555 | parties who would receive the covered work from you, a discriminatory 556 | patent license (a) in connection with copies of the covered work 557 | conveyed by you (or copies made from those copies), or (b) primarily 558 | for and in connection with specific products or compilations that 559 | contain the covered work, unless you entered into that arrangement, 560 | or that patent license was granted, prior to 28 March 2007. 561 | 562 | Nothing in this License shall be construed as excluding or limiting 563 | any implied license or other defenses to infringement that may 564 | otherwise be available to you under applicable patent law. 565 | 566 | 12. No Surrender of Others' Freedom. 567 | 568 | If conditions are imposed on you (whether by court order, agreement or 569 | otherwise) that contradict the conditions of this License, they do not 570 | excuse you from the conditions of this License. If you cannot convey a 571 | covered work so as to satisfy simultaneously your obligations under this 572 | License and any other pertinent obligations, then as a consequence you may 573 | not convey it at all. For example, if you agree to terms that obligate you 574 | to collect a royalty for further conveying from those to whom you convey 575 | the Program, the only way you could satisfy both those terms and this 576 | License would be to refrain entirely from conveying the Program. 577 | 578 | 13. Use with the GNU Affero General Public License. 579 | 580 | Notwithstanding any other provision of this License, you have 581 | permission to link or combine any covered work with a work licensed 582 | under version 3 of the GNU Affero General Public License into a single 583 | combined work, and to convey the resulting work. The terms of this 584 | License will continue to apply to the part which is the covered work, 585 | but the special requirements of the GNU Affero General Public License, 586 | section 13, concerning interaction through a network will apply to the 587 | combination as such. 588 | 589 | 14. Revised Versions of this License. 590 | 591 | The Free Software Foundation may publish revised and/or new versions of 592 | the GNU General Public License from time to time. Such new versions will 593 | be similar in spirit to the present version, but may differ in detail to 594 | address new problems or concerns. 595 | 596 | Each version is given a distinguishing version number. If the 597 | Program specifies that a certain numbered version of the GNU General 598 | Public License "or any later version" applies to it, you have the 599 | option of following the terms and conditions either of that numbered 600 | version or of any later version published by the Free Software 601 | Foundation. If the Program does not specify a version number of the 602 | GNU General Public License, you may choose any version ever published 603 | by the Free Software Foundation. 604 | 605 | If the Program specifies that a proxy can decide which future 606 | versions of the GNU General Public License can be used, that proxy's 607 | public statement of acceptance of a version permanently authorizes you 608 | to choose that version for the Program. 609 | 610 | Later license versions may give you additional or different 611 | permissions. However, no additional obligations are imposed on any 612 | author or copyright holder as a result of your choosing to follow a 613 | later version. 614 | 615 | 15. Disclaimer of Warranty. 616 | 617 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 618 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 619 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 620 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 621 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 622 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 623 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 624 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 625 | 626 | 16. Limitation of Liability. 627 | 628 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 629 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 630 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 631 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 632 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 633 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 634 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 635 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 636 | SUCH DAMAGES. 637 | 638 | 17. Interpretation of Sections 15 and 16. 639 | 640 | If the disclaimer of warranty and limitation of liability provided 641 | above cannot be given local legal effect according to their terms, 642 | reviewing courts shall apply local law that most closely approximates 643 | an absolute waiver of all civil liability in connection with the 644 | Program, unless a warranty or assumption of liability accompanies a 645 | copy of the Program in return for a fee. 646 | 647 | END OF TERMS AND CONDITIONS 648 | 649 | How to Apply These Terms to Your New Programs 650 | 651 | If you develop a new program, and you want it to be of the greatest 652 | possible use to the public, the best way to achieve this is to make it 653 | free software which everyone can redistribute and change under these terms. 654 | 655 | To do so, attach the following notices to the program. It is safest 656 | to attach them to the start of each source file to most effectively 657 | state the exclusion of warranty; and each file should have at least 658 | the "copyright" line and a pointer to where the full notice is found. 659 | 660 | 661 | Copyright (C) 662 | 663 | This program is free software: you can redistribute it and/or modify 664 | it under the terms of the GNU General Public License as published by 665 | the Free Software Foundation, either version 3 of the License, or 666 | (at your option) any later version. 667 | 668 | This program is distributed in the hope that it will be useful, 669 | but WITHOUT ANY WARRANTY; without even the implied warranty of 670 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 671 | GNU General Public License for more details. 672 | 673 | You should have received a copy of the GNU General Public License 674 | along with this program. If not, see . 675 | 676 | Also add information on how to contact you by electronic and paper mail. 677 | 678 | If the program does terminal interaction, make it output a short 679 | notice like this when it starts in an interactive mode: 680 | 681 | Copyright (C) 682 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 683 | This is free software, and you are welcome to redistribute it 684 | under certain conditions; type `show c' for details. 685 | 686 | The hypothetical commands `show w' and `show c' should show the appropriate 687 | parts of the General Public License. Of course, your program's commands 688 | might be different; for a GUI interface, you would use an "about box". 689 | 690 | You should also get your employer (if you work as a programmer) or school, 691 | if any, to sign a "copyright disclaimer" for the program, if necessary. 692 | For more information on this, and how to apply and follow the GNU GPL, see 693 | . 694 | 695 | The GNU General Public License does not permit incorporating your program 696 | into proprietary programs. If your program is a subroutine library, you 697 | may consider it more useful to permit linking proprietary applications with 698 | the library. If this is what you want to do, use the GNU Lesser General 699 | Public License instead of this License. But first, please read 700 | . 701 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | ![zca logo](http://imageshack.com/a/img911/7375/ZWHW5Y.png) 2 | 3 | [![Gitter](https://badges.gitter.im/zdharma-continuum/community.svg)](https://gitter.im/zdharma-continuum/community?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge) 4 | 5 | # Zsh Command Architect 6 | 7 | Also check out 8 | [![ZNT](http://imageshack.com/a/img910/3618/oDHnuR.png) Zsh Navigation Tools](https://github.com/zdharma-continuum/zsh-navigation-tools) 9 | and 10 | [![ZEW](http://imageshack.com/a/img908/3869/Vsd2c6.png) Zsh Editing Workbench](https://github.com/zdharma-continuum/zsh-editing-workbench) 11 | 12 | Zsh Command Architect in action: ![zca](http://imageshack.com/a/img905/3617/grLOeP.gif) 13 | 14 | ## Installation 15 | 16 | ``` 17 | sh -c "$(curl -fsSL https://raw.githubusercontent.com/zdharma-continuum/zsh-cmd-architect/master/doc/install.sh)" 18 | ``` 19 | 20 | To update run the command again. 21 | 22 | `ZCA` will be installed at `~/.config/zca/zsh-cmd-architect`, config files will be copied to `~/.config/zca`. `.zshrc` 23 | will be updated with only `4` lines of code that will be added to the bottom. 24 | 25 | After installing and reloading shell give `ZCA` a quick try with `Ctrl-T`. 26 | 27 | ## Installation With [Zinit](https://github.com/zdharma-continuum/zinit) 28 | 29 | Add `zinit load zdharma-continuum/zsh-cmd-architect` to `.zshrc`. The config files will be available in `~/.config/zca`. 30 | 31 | ## Installation With Zgen 32 | 33 | Add `zgen load zdharma-continuum/zsh-cmd-architect` to `.zshrc` and issue a `zgen reset` (this assumes that there is a 34 | proper `zgen save` construct in `.zshrc`). The config files will be available in `~/.config/zca`. 35 | 36 | ## Installation With Antigen 37 | 38 | Add `antigen bundle zdharma-continuum/zsh-cmd-architect` to `.zshrc`. There also should be `antigen apply`. The config 39 | files will be in `~/.config/znt`. 40 | 41 | ## Manual Installation 42 | 43 | After extracting `ZCA` to `{some-directory}` add following two lines to `~/.zshrc`: 44 | 45 | ```zsh 46 | fpath+=( {some-directory} ) 47 | source "{some-directory}/zsh-cmd-architect.plugin.zsh" 48 | ``` 49 | 50 | As you can see, no plugin manager is needed to use the `*.plugin.zsh` file. The above two lines of code are all that 51 | almost **all** plugin managers do. In fact, what's actually needed is only: 52 | 53 | ```zsh 54 | source "{some-directory}/zsh-cmd-architect.plugin.zsh" 55 | ``` 56 | 57 | because `ZCA` detects if it is used by **any** plugin manager and can handle `$fpath` update by itself. 58 | 59 | ## Single File Manual Installation 60 | 61 | Running script `doc/generate_single_file` will create single-file version of `ZCA`. It can be sourced from `.zshrc`. 62 | Don't forget about configuration files (copy them to `~/.config/zca`). 63 | 64 | ## Introduction 65 | 66 | `ZCA` allows to copy segments of commands in history, rearrange segments of current command, delete segments of current 67 | command. This way user glues command from parts without using a mouse. Advanced history search (multi word, without 68 | duplicate lines) allows to quickly find the parts. 69 | 70 | Keys are: 71 | 72 | - `Ctrl-T` - start Zsh Command Architect (Zshell binding) 73 | - `Enter` - delete selected segment (when in command window) or add selected segment (when in history window) 74 | - `[` or `]` - move active segment (when in command window) 75 | - `Shift-left` or `Shift-right` - move active segment (when in command window) 76 | - `Tab` - switch between the two available windows 77 | - `g, G` - beginning and end of the list 78 | - `/` - start incremental search 79 | - `Esc` - exit incremental search, clearing filter 80 | - `<`,`>`, `{`,`}` - horizontal scroll 81 | - `Ctrl-L` - redraw of whole display 82 | - `Ctrl-O`, `o` - enter uniq mode (no duplicate lines) 83 | - `Ctrl-W` (in incremental search) - delete whole word 84 | - `Ctrl-K` (in incremental search) - delete whole line 85 | - `Ctrl-D`, `Ctrl-U` - half page up or down 86 | - `Ctrl-P`, `Ctrl-N` - previous and next (also done with vim's j,k) 87 | 88 | ## Performance 89 | 90 | `ZCA` is fastest with `Zsh` before `5.0.6` and starting from `5.2` 91 | 92 | # Fixing tmux, screen and linux vt 93 | 94 | If `TERM=screen-256color` (often a case for `tmux` and `screen` sessions) then `ncv` terminfo capability will have `2`nd 95 | bit set. This in general means that underline won't work. To fix this by creating your own `ncv=0`-equipped terminfo 96 | file, run: 97 | 98 | ```zsh 99 | { infocmp -x screen-256color; printf '\t%s\n' 'ncv@,'; } > /tmp/t && tic -x /tmp/t 100 | ``` 101 | 102 | A file will be created in directory `~/.terminfo` and will be automatically used, `tmux` and `screen` will work. Similar 103 | is for Linux virtual terminal: 104 | 105 | ```zsh 106 | { infocmp -x linux; printf '\t%s\n' 'ncv@,'; } > /tmp/t && tic -x /tmp/t 107 | ``` 108 | 109 | It will not display underline properly, but will instead highlight by a color, which is quite nice. The same will not 110 | work for FreeBSD's vt, `ZCA` will detect if that vt is used and will revert to highlighting elements via `reverse` mode. 111 | -------------------------------------------------------------------------------- /doc/generate_single_file: -------------------------------------------------------------------------------- 1 | #!/bin/zsh 2 | 3 | local PLUGIN_FILE="doc/zshcmdarchitect.plugin.zsh" 4 | 5 | [ -d doc ] || cd .. 6 | 7 | rm -vf "$PLUGIN_FILE" 8 | echo "# https://github.com/psprint/zsh-cmd-architect" >>"$PLUGIN_FILE" 9 | echo "# License is GPLv3 and MIT" >>"$PLUGIN_FILE" 10 | echo -n "# " >>"$PLUGIN_FILE" 11 | git show-ref master | head -1 >>"$PLUGIN_FILE" 12 | echo >>"$PLUGIN_FILE" 13 | 14 | for i in h-*(on) zca zca-*(on);
