Additional Definitions. 14 | 15 | As used herein, "this License" refers to version 3 of the GNU Lesser 16 | General Public License, and the "GNU GPL" refers to version 3 of the GNU 17 | General Public License. 18 | 19 | "The Library" refers to a covered work governed by this License, 20 | other than an Application or a Combined Work as defined below. 21 | 22 | An "Application" is any work that makes use of an interface provided 23 | by the Library, but which is not otherwise based on the Library. 24 | Defining a subclass of a class defined by the Library is deemed a mode 25 | of using an interface provided by the Library. 26 | 27 | A "Combined Work" is a work produced by combining or linking an 28 | Application with the Library. The particular version of the Library 29 | with which the Combined Work was made is also called the "Linked 30 | Version". 31 | 32 | The "Minimal Corresponding Source" for a Combined Work means the 33 | Corresponding Source for the Combined Work, excluding any source code 34 | for portions of the Combined Work that, considered in isolation, are 35 | based on the Application, and not on the Linked Version. 36 | 37 | The "Corresponding Application Code" for a Combined Work means the 38 | object code and/or source code for the Application, including any data 39 | and utility programs needed for reproducing the Combined Work from the 40 | Application, but excluding the System Libraries of the Combined Work. 41 | 42 | 1. Exception to Section 3 of the GNU GPL. 43 | 44 | You may convey a covered work under sections 3 and 4 of this License 45 | without being bound by section 3 of the GNU GPL. 46 | 47 | 2. Conveying Modified Versions. 48 | 49 | If you modify a copy of the Library, and, in your modifications, a 50 | facility refers to a function or data to be supplied by an Application 51 | that uses the facility (other than as an argument passed when the 52 | facility is invoked), then you may convey a copy of the modified 53 | version: 54 | 55 | a) under this License, provided that you make a good faith effort to 56 | ensure that, in the event an Application does not supply the 57 | function or data, the facility still operates, and performs 58 | whatever part of its purpose remains meaningful, or 59 | 60 | b) under the GNU GPL, with none of the additional permissions of 61 | this License applicable to that copy. 62 | 63 | 3. Object Code Incorporating Material from Library Header Files. 64 | 65 | The object code form of an Application may incorporate material from 66 | a header file that is part of the Library. You may convey such object 67 | code under terms of your choice, provided that, if the incorporated 68 | material is not limited to numerical parameters, data structure 69 | layouts and accessors, or small macros, inline functions and templates 70 | (ten or fewer lines in length), you do both of the following: 71 | 72 | a) Give prominent notice with each copy of the object code that the 73 | Library is used in it and that the Library and its use are 74 | covered by this License. 75 | 76 | b) Accompany the object code with a copy of the GNU GPL and this license 77 | document. 78 | 79 | 4. Combined Works. 80 | 81 | You may convey a Combined Work under terms of your choice that, 82 | taken together, effectively do not restrict modification of the 83 | portions of the Library contained in the Combined Work and reverse 84 | engineering for debugging such modifications, if you also do each of 85 | the following: 86 | 87 | a) Give prominent notice with each copy of the Combined Work that 88 | the Library is used in it and that the Library and its use are 89 | covered by this License. 90 | 91 | b) Accompany the Combined Work with a copy of the GNU GPL and this license 92 | document. 93 | 94 | c) For a Combined Work that displays copyright notices during 95 | execution, include the copyright notice for the Library among 96 | these notices, as well as a reference directing the user to the 97 | copies of the GNU GPL and this license document. 98 | 99 | d) Do one of the following: 100 | 101 | 0) Convey the Minimal Corresponding Source under the terms of this 102 | License, and the Corresponding Application Code in a form 103 | suitable for, and under terms that permit, the user to 104 | recombine or relink the Application with a modified version of 105 | the Linked Version to produce a modified Combined Work, in the 106 | manner specified by section 6 of the GNU GPL for conveying 107 | Corresponding Source. 108 | 109 | 1) Use a suitable shared library mechanism for linking with the 110 | Library. A suitable mechanism is one that (a) uses at run time 111 | a copy of the Library already present on the user's computer 112 | system, and (b) will operate properly with a modified version 113 | of the Library that is interface-compatible with the Linked 114 | Version. 115 | 116 | e) Provide Installation Information, but only if you would otherwise 117 | be required to provide such information under section 6 of the 118 | GNU GPL, and only to the extent that such information is 119 | necessary to install and execute a modified version of the 120 | Combined Work produced by recombining or relinking the 121 | Application with a modified version of the Linked Version. (If 122 | you use option 4d0, the Installation Information must accompany 123 | the Minimal Corresponding Source and Corresponding Application 124 | Code. If you use option 4d1, you must provide the Installation 125 | Information in the manner specified by section 6 of the GNU GPL 126 | for conveying Corresponding Source.) 127 | 128 | 5. Combined Libraries. 129 | 130 | You may place library facilities that are a work based on the 131 | Library side by side in a single library together with other library 132 | facilities that are not Applications and are not covered by this 133 | License, and convey such a combined library under terms of your 134 | choice, if you do both of the following: 135 | 136 | a) Accompany the combined library with a copy of the same work based 137 | on the Library, uncombined with any other library facilities, 138 | conveyed under the terms of this License. 139 | 140 | b) Give prominent notice with the combined library that part of it 141 | is a work based on the Library, and explaining where to find the 142 | accompanying uncombined form of the same work. 143 | 144 | 6. Revised Versions of the GNU Lesser General Public License. 145 | 146 | The Free Software Foundation may publish revised and/or new versions 147 | of the GNU Lesser General Public License from time to time. Such new 148 | versions will be similar in spirit to the present version, but may 149 | differ in detail to address new problems or concerns. 150 | 151 | Each version is given a distinguishing version number. If the 152 | Library as you received it specifies that a certain numbered version 153 | of the GNU Lesser General Public License "or any later version" 154 | applies to it, you have the option of following the terms and 155 | conditions either of that published version or of any later version 156 | published by the Free Software Foundation. If the Library as you 157 | received it does not specify a version number of the GNU Lesser 158 | General Public License, you may choose any version of the GNU Lesser 159 | General Public License ever published by the Free Software Foundation. 160 | 161 | If the Library as you received it specifies that a proxy can decide 162 | whether future versions of the GNU Lesser General Public License shall 163 | apply, that proxy's public statement of acceptance of any version is 164 | permanent authorization for you to choose that version for the 165 | Library. 166 | 167 | GNU GENERAL PUBLIC LICENSE 168 | Version 3, 29 June 2007 169 | 170 | Copyright (C) 2007 Free Software Foundation, Inc. 171 | Everyone is permitted to copy and distribute verbatim copies 172 | of this license document, but changing it is not allowed. 173 | 174 | Preamble 175 | 176 | The GNU General Public License is a free, copyleft license for 177 | software and other kinds of works. 178 | 179 | The licenses for most software and other practical works are designed 180 | to take away your freedom to share and change the works. By contrast, 181 | the GNU General Public License is intended to guarantee your freedom to 182 | share and change all versions of a program--to make sure it remains free 183 | software for all its users. We, the Free Software Foundation, use the 184 | GNU General Public License for most of our software; it applies also to 185 | any other work released this way by its authors. You can apply it to 186 | your programs, too. 187 | 188 | When we speak of free software, we are referring to freedom, not 189 | price. Our General Public Licenses are designed to make sure that you 190 | have the freedom to distribute copies of free software (and charge for 191 | them if you wish), that you receive source code or can get it if you 192 | want it, that you can change the software or use pieces of it in new 193 | free programs, and that you know you can do these things. 194 | 195 | To protect your rights, we need to prevent others from denying you 196 | these rights or asking you to surrender the rights. Therefore, you have 197 | certain responsibilities if you distribute copies of the software, or if 198 | you modify it: responsibilities to respect the freedom of others. 199 | 200 | For example, if you distribute copies of such a program, whether 201 | gratis or for a fee, you must pass on to the recipients the same 202 | freedoms that you received. You must make sure that they, too, receive 203 | or can get the source code. And you must show them these terms so they 204 | know their rights. 205 | 206 | Developers that use the GNU GPL protect your rights with two steps: 207 | (1) assert copyright on the software, and (2) offer you this License 208 | giving you legal permission to copy, distribute and/or modify it. 209 | 210 | For the developers' and authors' protection, the GPL clearly explains 211 | that there is no warranty for this free software. For both users' and 212 | authors' sake, the GPL requires that modified versions be marked as 213 | changed, so that their problems will not be attributed erroneously to 214 | authors of previous versions. 215 | 216 | Some devices are designed to deny users access to install or run 217 | modified versions of the software inside them, although the manufacturer 218 | can do so. This is fundamentally incompatible with the aim of 219 | protecting users' freedom to change the software. The systematic 220 | pattern of such abuse occurs in the area of products for individuals to 221 | use, which is precisely where it is most unacceptable. Therefore, we 222 | have designed this version of the GPL to prohibit the practice for those 223 | products. If such problems arise substantially in other domains, we 224 | stand ready to extend this provision to those domains in future versions 225 | of the GPL, as needed to protect the freedom of users. 226 | 227 | Finally, every program is threatened constantly by software patents. 228 | States should not allow patents to restrict development and use of 229 | software on general-purpose computers, but in those that do, we wish to 230 | avoid the special danger that patents applied to a free program could 231 | make it effectively proprietary. To prevent this, the GPL assures that 232 | patents cannot be used to render the program non-free. 233 | 234 | The precise terms and conditions for copying, distribution and 235 | modification follow. 236 | 237 | TERMS AND CONDITIONS 238 | 239 | 0. Definitions. 240 | 241 | "This License" refers to version 3 of the GNU General Public License. 242 | 243 | "Copyright" also means copyright-like laws that apply to other kinds of 244 | works, such as semiconductor masks. 245 | 246 | "The Program" refers to any copyrightable work licensed under this 247 | License. Each licensee is addressed as "you". "Licensees" and 248 | "recipients" may be individuals or organizations. 249 | 250 | To "modify" a work means to copy from or adapt all or part of the work 251 | in a fashion requiring copyright permission, other than the making of an 252 | exact copy. The resulting work is called a "modified version" of the 253 | earlier work or a work "based on" the earlier work. 254 | 255 | A "covered work" means either the unmodified Program or a work based 256 | on the Program. 257 | 258 | To "propagate" a work means to do anything with it that, without 259 | permission, would make you directly or secondarily liable for 260 | infringement under applicable copyright law, except executing it on a 261 | computer or modifying a private copy. Propagation includes copying, 262 | distribution (with or without modification), making available to the 263 | public, and in some countries other activities as well. 264 | 265 | To "convey" a work means any kind of propagation that enables other 266 | parties to make or receive copies. Mere interaction with a user through 267 | a computer network, with no transfer of a copy, is not conveying. 268 | 269 | An interactive user interface displays "Appropriate Legal Notices" 270 | to the extent that it includes a convenient and prominently visible 271 | feature that (1) displays an appropriate copyright notice, and (2) 272 | tells the user that there is no warranty for the work (except to the 273 | extent that warranties are provided), that licensees may convey the 274 | work under this License, and how to view a copy of this License. If 275 | the interface presents a list of user commands or options, such as a 276 | menu, a prominent item in the list meets this criterion. 277 | 278 | 1. Source Code. 279 | 280 | The "source code" for a work means the preferred form of the work 281 | for making modifications to it. "Object code" means any non-source 282 | form of a work. 283 | 284 | A "Standard Interface" means an interface that either is an official 285 | standard defined by a recognized standards body, or, in the case of 286 | interfaces specified for a particular programming language, one that 287 | is widely used among developers working in that language. 288 | 289 | The "System Libraries" of an executable work include anything, other 290 | than the work as a whole, that (a) is included in the normal form of 291 | packaging a Major Component, but which is not part of that Major 292 | Component, and (b) serves only to enable use of the work with that 293 | Major Component, or to implement a Standard Interface for which an 294 | implementation is available to the public in source code form. A 295 | "Major Component", in this context, means a major essential component 296 | (kernel, window system, and so on) of the specific operating system 297 | (if any) on which the executable work runs, or a compiler used to 298 | produce the work, or an object code interpreter used to run it. 299 | 300 | The "Corresponding Source" for a work in object code form means all 301 | the source code needed to generate, install, and (for an executable 302 | work) run the object code and to modify the work, including scripts to 303 | control those activities. However, it does not include the work's 304 | System Libraries, or general-purpose tools or generally available free 305 | programs which are used unmodified in performing those activities but 306 | which are not part of the work. For example, Corresponding Source 307 | includes interface definition files associated with source files for 308 | the work, and the source code for shared libraries and dynamically 309 | linked subprograms that the work is specifically designed to require, 310 | such as by intimate data communication or control flow between those 311 | subprograms and other parts of the work. 312 | 313 | The Corresponding Source need not include anything that users 314 | can regenerate automatically from other parts of the Corresponding 315 | Source. 316 | 317 | The Corresponding Source for a work in source code form is that 318 | same work. 319 | 320 | 2. Basic Permissions. 321 | 322 | All rights granted under this License are granted for the term of 323 | copyright on the Program, and are irrevocable provided the stated 324 | conditions are met. This License explicitly affirms your unlimited 325 | permission to run the unmodified Program. The output from running a 326 | covered work is covered by this License only if the output, given its 327 | content, constitutes a covered work. This License acknowledges your 328 | rights of fair use or other equivalent, as provided by copyright law. 329 | 330 | You may make, run and propagate covered works that you do not 331 | convey, without conditions so long as your license otherwise remains 332 | in force. You may convey covered works to others for the sole purpose 333 | of having them make modifications exclusively for you, or provide you 334 | with facilities for running those works, provided that you comply with 335 | the terms of this License in conveying all material for which you do 336 | not control copyright. Those thus making or running the covered works 337 | for you must do so exclusively on your behalf, under your direction 338 | and control, on terms that prohibit them from making any copies of 339 | your copyrighted material outside their relationship with you. 340 | 341 | Conveying under any other circumstances is permitted solely under 342 | the conditions stated below. Sublicensing is not allowed; section 10 343 | makes it unnecessary. 344 | 345 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 346 | 347 | No covered work shall be deemed part of an effective technological 348 | measure under any applicable law fulfilling obligations under article 349 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or 350 | similar laws prohibiting or restricting circumvention of such 351 | measures. 352 | 353 | When you convey a covered work, you waive any legal power to forbid 354 | circumvention of technological measures to the extent such circumvention 355 | is effected by exercising rights under this License with respect to 356 | the covered work, and you disclaim any intention to limit operation or 357 | modification of the work as a means of enforcing, against the work's 358 | users, your or third parties' legal rights to forbid circumvention of 359 | technological measures. 360 | 361 | 4. Conveying Verbatim Copies. 362 | 363 | You may convey verbatim copies of the Program's source code as you 364 | receive it, in any medium, provided that you conspicuously and 365 | appropriately publish on each copy an appropriate copyright notice; 366 | keep intact all notices stating that this License and any 367 | non-permissive terms added in accord with section 7 apply to the code; 368 | keep intact all notices of the absence of any warranty; and give all 369 | recipients a copy of this License along with the Program. 370 | 371 | You may charge any price or no price for each copy that you convey, 372 | and you may offer support or warranty protection for a fee. 373 | 374 | 5. Conveying Modified Source Versions. 375 | 376 | You may convey a work based on the Program, or the modifications to 377 | produce it from the Program, in the form of source code under the 378 | terms of section 4, provided that you also meet all of these conditions: 379 | 380 | a) The work must carry prominent notices stating that you modified 381 | it, and giving a relevant date. 382 | 383 | b) The work must carry prominent notices stating that it is 384 | released under this License and any conditions added under section 385 | 7. This requirement modifies the requirement in section 4 to 386 | "keep intact all notices". 387 | 388 | c) You must license the entire work, as a whole, under this 389 | License to anyone who comes into possession of a copy. This 390 | License will therefore apply, along with any applicable section 7 391 | additional terms, to the whole of the work, and all its parts, 392 | regardless of how they are packaged. This License gives no 393 | permission to license the work in any other way, but it does not 394 | invalidate such permission if you have separately received it. 395 | 396 | d) If the work has interactive user interfaces, each must display 397 | Appropriate Legal Notices; however, if the Program has interactive 398 | interfaces that do not display Appropriate Legal Notices, your 399 | work need not make them do so. 400 | 401 | A compilation of a covered work with other separate and independent 402 | works, which are not by their nature extensions of the covered work, 403 | and which are not combined with it such as to form a larger program, 404 | in or on a volume of a storage or distribution medium, is called an 405 | "aggregate" if the compilation and its resulting copyright are not 406 | used to limit the access or legal rights of the compilation's users 407 | beyond what the individual works permit. Inclusion of a covered work 408 | in an aggregate does not cause this License to apply to the other 409 | parts of the aggregate. 410 | 411 | 6. Conveying Non-Source Forms. 412 | 413 | You may convey a covered work in object code form under the terms 414 | of sections 4 and 5, provided that you also convey the 415 | machine-readable Corresponding Source under the terms of this License, 416 | in one of these ways: 417 | 418 | a) Convey the object code in, or embodied in, a physical product 419 | (including a physical distribution medium), accompanied by the 420 | Corresponding Source fixed on a durable physical medium 421 | customarily used for software interchange. 422 | 423 | b) Convey the object code in, or embodied in, a physical product 424 | (including a physical distribution medium), accompanied by a 425 | written offer, valid for at least three years and valid for as 426 | long as you offer spare parts or customer support for that product 427 | model, to give anyone who possesses the object code either (1) a 428 | copy of the Corresponding Source for all the software in the 429 | product that is covered by this License, on a durable physical 430 | medium customarily used for software interchange, for a price no 431 | more than your reasonable cost of physically performing this 432 | conveying of source, or (2) access to copy the 433 | Corresponding Source from a network server at no charge. 434 | 435 | c) Convey individual copies of the object code with a copy of the 436 | written offer to provide the Corresponding Source. This 437 | alternative is allowed only occasionally and noncommercially, and 438 | only if you received the object code with such an offer, in accord 439 | with subsection 6b. 440 | 441 | d) Convey the object code by offering access from a designated 442 | place (gratis or for a charge), and offer equivalent access to the 443 | Corresponding Source in the same way through the same place at no 444 | further charge. You need not require recipients to copy the 445 | Corresponding Source along with the object code. If the place to 446 | copy the object code is a network server, the Corresponding Source 447 | may be on a different server (operated by you or a third party) 448 | that supports equivalent copying facilities, provided you maintain 449 | clear directions next to the object code saying where to find the 450 | Corresponding Source. Regardless of what server hosts the 451 | Corresponding Source, you remain obligated to ensure that it is 452 | available for as long as needed to satisfy these requirements. 453 | 454 | e) Convey the object code using peer-to-peer transmission, provided 455 | you inform other peers where the object code and Corresponding 456 | Source of the work are being offered to the general public at no 457 | charge under subsection 6d. 458 | 459 | A separable portion of the object code, whose source code is excluded 460 | from the Corresponding Source as a System Library, need not be 461 | included in conveying the object code work. 462 | 463 | A "User Product" is either (1) a "consumer product", which means any 464 | tangible personal property which is normally used for personal, family, 465 | or household purposes, or (2) anything designed or sold for incorporation 466 | into a dwelling. In determining whether a product is a consumer product, 467 | doubtful cases shall be resolved in favor of coverage. For a particular 468 | product received by a particular user, "normally used" refers to a 469 | typical or common use of that class of product, regardless of the status 470 | of the particular user or of the way in which the particular user 471 | actually uses, or expects or is expected to use, the product. A product 472 | is a consumer product regardless of whether the product has substantial 473 | commercial, industrial or non-consumer uses, unless such uses represent 474 | the only significant mode of use of the product. 475 | 476 | "Installation Information" for a User Product means any methods, 477 | procedures, authorization keys, or other information required to install 478 | and execute modified versions of a covered work in that User Product from 479 | a modified version of its Corresponding Source. The information must 480 | suffice to ensure that the continued functioning of the modified object 481 | code is in no case prevented or interfered with solely because 482 | modification has been made. 483 | 484 | If you convey an object code work under this section in, or with, or 485 | specifically for use in, a User Product, and the conveying occurs as 486 | part of a transaction in which the right of possession and use of the 487 | User Product is transferred to the recipient in perpetuity or for a 488 | fixed term (regardless of how the transaction is characterized), the 489 | Corresponding Source conveyed under this section must be accompanied 490 | by the Installation Information. But this requirement does not apply 491 | if neither you nor any third party retains the ability to install 492 | modified object code on the User Product (for example, the work has 493 | been installed in ROM). 494 | 495 | The requirement to provide Installation Information does not include a 496 | requirement to continue to provide support service, warranty, or updates 497 | for a work that has been modified or installed by the recipient, or for 498 | the User Product in which it has been modified or installed. Access to a 499 | network may be denied when the modification itself materially and 500 | adversely affects the operation of the network or violates the rules and 501 | protocols for communication across the network. 502 | 503 | Corresponding Source conveyed, and Installation Information provided, 504 | in accord with this section must be in a format that is publicly 505 | documented (and with an implementation available to the public in 506 | source code form), and must require no special password or key for 507 | unpacking, reading or copying. 508 | 509 | 7. Additional Terms. 510 | 511 | "Additional permissions" are terms that supplement the terms of this 512 | License by making exceptions from one or more of its conditions. 513 | Additional permissions that are applicable to the entire Program shall 514 | be treated as though they were included in this License, to the extent 515 | that they are valid under applicable law. If additional permissions 516 | apply only to part of the Program, that part may be used separately 517 | under those permissions, but the entire Program remains governed by 518 | this License without regard to the additional permissions. 519 | 520 | When you convey a copy of a covered work, you may at your option 521 | remove any additional permissions from that copy, or from any part of 522 | it. (Additional permissions may be written to require their own 523 | removal in certain cases when you modify the work.) You may place 524 | additional permissions on material, added by you to a covered work, 525 | for which you have or can give appropriate copyright permission. 526 | 527 | Notwithstanding any other provision of this License, for material you 528 | add to a covered work, you may (if authorized by the copyright holders of 529 | that material) supplement the terms of this License with terms: 530 | 531 | a) Disclaiming warranty or limiting liability differently from the 532 | terms of sections 15 and 16 of this License; or 533 | 534 | b) Requiring preservation of specified reasonable legal notices or 535 | author attributions in that material or in the Appropriate Legal 536 | Notices displayed by works containing it; or 537 | 538 | c) Prohibiting misrepresentation of the origin of that material, or 539 | requiring that modified versions of such material be marked in 540 | reasonable ways as different from the original version; or 541 | 542 | d) Limiting the use for publicity purposes of names of licensors or 543 | authors of the material; or 544 | 545 | e) Declining to grant rights under trademark law for use of some 546 | trade names, trademarks, or service marks; or 547 | 548 | f) Requiring indemnification of licensors and authors of that 549 | material by anyone who conveys the material (or modified versions of 550 | it) with contractual assumptions of liability to the recipient, for 551 | any liability that these contractual assumptions directly impose on 552 | those licensors and authors. 553 | 554 | All other non-permissive additional terms are considered "further 555 | restrictions" within the meaning of section 10. If the Program as you 556 | received it, or any part of it, contains a notice stating that it is 557 | governed by this License along with a term that is a further 558 | restriction, you may remove that term. If a license document contains 559 | a further restriction but permits relicensing or conveying under this 560 | License, you may add to a covered work material governed by the terms 561 | of that license document, provided that the further restriction does 562 | not survive such relicensing or conveying. 563 | 564 | If you add terms to a covered work in accord with this section, you 565 | must place, in the relevant source files, a statement of the 566 | additional terms that apply to those files, or a notice indicating 567 | where to find the applicable terms. 568 | 569 | Additional terms, permissive or non-permissive, may be stated in the 570 | form of a separately written license, or stated as exceptions; 571 | the above requirements apply either way. 572 | 573 | 8. Termination. 574 | 575 | You may not propagate or modify a covered work except as expressly 576 | provided under this License. Any attempt otherwise to propagate or 577 | modify it is void, and will automatically terminate your rights under 578 | this License (including any patent licenses granted under the third 579 | paragraph of section 11). 580 | 581 | However, if you cease all violation of this License, then your 582 | license from a particular copyright holder is reinstated (a) 583 | provisionally, unless and until the copyright holder explicitly and 584 | finally terminates your license, and (b) permanently, if the copyright 585 | holder fails to notify you of the violation by some reasonable means 586 | prior to 60 days after the cessation. 587 | 588 | Moreover, your license from a particular copyright holder is 589 | reinstated permanently if the copyright holder notifies you of the 590 | violation by some reasonable means, this is the first time you have 591 | received notice of violation of this License (for any work) from that 592 | copyright holder, and you cure the violation prior to 30 days after 593 | your receipt of the notice. 594 | 595 | Termination of your rights under this section does not terminate the 596 | licenses of parties who have received copies or rights from you under 597 | this License. If your rights have been terminated and not permanently 598 | reinstated, you do not qualify to receive new licenses for the same 599 | material under section 10. 600 | 601 | 9. Acceptance Not Required for Having Copies. 602 | 603 | You are not required to accept this License in order to receive or 604 | run a copy of the Program. Ancillary propagation of a covered work 605 | occurring solely as a consequence of using peer-to-peer transmission 606 | to receive a copy likewise does not require acceptance. However, 607 | nothing other than this License grants you permission to propagate or 608 | modify any covered work. These actions infringe copyright if you do 609 | not accept this License. Therefore, by modifying or propagating a 610 | covered work, you indicate your acceptance of this License to do so. 611 | 612 | 10. Automatic Licensing of Downstream Recipients. 613 | 614 | Each time you convey a covered work, the recipient automatically 615 | receives a license from the original licensors, to run, modify and 616 | propagate that work, subject to this License. You are not responsible 617 | for enforcing compliance by third parties with this License. 618 | 619 | An "entity transaction" is a transaction transferring control of an 620 | organization, or substantially all assets of one, or subdividing an 621 | organization, or merging organizations. If propagation of a covered 622 | work results from an entity transaction, each party to that 623 | transaction who receives a copy of the work also receives whatever 624 | licenses to the work the party's predecessor in interest had or could 625 | give under the previous paragraph, plus a right to possession of the 626 | Corresponding Source of the work from the predecessor in interest, if 627 | the predecessor has it or can get it with reasonable efforts. 628 | 629 | You may not impose any further restrictions on the exercise of the 630 | rights granted or affirmed under this License. For example, you may 631 | not impose a license fee, royalty, or other charge for exercise of 632 | rights granted under this License, and you may not initiate litigation 633 | (including a cross-claim or counterclaim in a lawsuit) alleging that 634 | any patent claim is infringed by making, using, selling, offering for 635 | sale, or importing the Program or any portion of it. 636 | 637 | 11. Patents. 638 | 639 | A "contributor" is a copyright holder who authorizes use under this 640 | License of the Program or a work on which the Program is based. The 641 | work thus licensed is called the contributor's "contributor version". 642 | 643 | A contributor's "essential patent claims" are all patent claims 644 | owned or controlled by the contributor, whether already acquired or 645 | hereafter acquired, that would be infringed by some manner, permitted 646 | by this License, of making, using, or selling its contributor version, 647 | but do not include claims that would be infringed only as a 648 | consequence of further modification of the contributor version. For 649 | purposes of this definition, "control" includes the right to grant 650 | patent sublicenses in a manner consistent with the requirements of 651 | this License. 652 | 653 | Each contributor grants you a non-exclusive, worldwide, royalty-free 654 | patent license under the contributor's essential patent claims, to 655 | make, use, sell, offer for sale, import and otherwise run, modify and 656 | propagate the contents of its contributor version. 657 | 658 | In the following three paragraphs, a "patent license" is any express 659 | agreement or commitment, however denominated, not to enforce a patent 660 | (such as an express permission to practice a patent or covenant not to 661 | sue for patent infringement). To "grant" such a patent license to a 662 | party means to make such an agreement or commitment not to enforce a 663 | patent against the party. 664 | 665 | If you convey a covered work, knowingly relying on a patent license, 666 | and the Corresponding Source of the work is not available for anyone 667 | to copy, free of charge and under the terms of this License, through a 668 | publicly available network server or other readily accessible means, 669 | then you must either (1) cause the Corresponding Source to be so 670 | available, or (2) arrange to deprive yourself of the benefit of the 671 | patent license for this particular work, or (3) arrange, in a manner 672 | consistent with the requirements of this License, to extend the patent 673 | license to downstream recipients. "Knowingly relying" means you have 674 | actual knowledge that, but for the patent license, your conveying the 675 | covered work in a country, or your recipient's use of the covered work 676 | in a country, would infringe one or more identifiable patents in that 677 | country that you have reason to believe are valid. 678 | 679 | If, pursuant to or in connection with a single transaction or 680 | arrangement, you convey, or propagate by procuring conveyance of, a 681 | covered work, and grant a patent license to some of the parties 682 | receiving the covered work authorizing them to use, propagate, modify 683 | or convey a specific copy of the covered work, then the patent license 684 | you grant is automatically extended to all recipients of the covered 685 | work and works based on it. 686 | 687 | A patent license is "discriminatory" if it does not include within 688 | the scope of its coverage, prohibits the exercise of, or is 689 | conditioned on the non-exercise of one or more of the rights that are 690 | specifically granted under this License. You may not convey a covered 691 | work if you are a party to an arrangement with a third party that is 692 | in the business of distributing software, under which you make payment 693 | to the third party based on the extent of your activity of conveying 694 | the work, and under which the third party grants, to any of the 695 | parties who would receive the covered work from you, a discriminatory 696 | patent license (a) in connection with copies of the covered work 697 | conveyed by you (or copies made from those copies), or (b) primarily 698 | for and in connection with specific products or compilations that 699 | contain the covered work, unless you entered into that arrangement, 700 | or that patent license was granted, prior to 28 March 2007. 701 | 702 | Nothing in this License shall be construed as excluding or limiting 703 | any implied license or other defenses to infringement that may 704 | otherwise be available to you under applicable patent law. 705 | 706 | 12. No Surrender of Others' Freedom. 707 | 708 | If conditions are imposed on you (whether by court order, agreement or 709 | otherwise) that contradict the conditions of this License, they do not 710 | excuse you from the conditions of this License. If you cannot convey a 711 | covered work so as to satisfy simultaneously your obligations under this 712 | License and any other pertinent obligations, then as a consequence you may 713 | not convey it at all. For example, if you agree to terms that obligate you 714 | to collect a royalty for further conveying from those to whom you convey 715 | the Program, the only way you could satisfy both those terms and this 716 | License would be to refrain entirely from conveying the Program. 717 | 718 | 13. Use with the GNU Affero General Public License. 719 | 720 | Notwithstanding any other provision of this License, you have 721 | permission to link or combine any covered work with a work licensed 722 | under version 3 of the GNU Affero General Public License into a single 723 | combined work, and to convey the resulting work. The terms of this 724 | License will continue to apply to the part which is the covered work, 725 | but the special requirements of the GNU Affero General Public License, 726 | section 13, concerning interaction through a network will apply to the 727 | combination as such. 728 | 729 | 14. Revised Versions of this License. 730 | 731 | The Free Software Foundation may publish revised and/or new versions of 732 | the GNU General Public License from time to time. Such new versions will 733 | be similar in spirit to the present version, but may differ in detail to 734 | address new problems or concerns. 735 | 736 | Each version is given a distinguishing version number. If the 737 | Program specifies that a certain numbered version of the GNU General 738 | Public License "or any later version" applies to it, you have the 739 | option of following the terms and conditions either of that numbered 740 | version or of any later version published by the Free Software 741 | Foundation. If the Program does not specify a version number of the 742 | GNU General Public License, you may choose any version ever published 743 | by the Free Software Foundation. 744 | 745 | If the Program specifies that a proxy can decide which future 746 | versions of the GNU General Public License can be used, that proxy's 747 | public statement of acceptance of a version permanently authorizes you 748 | to choose that version for the Program. 749 | 750 | Later license versions may give you additional or different 751 | permissions. However, no additional obligations are imposed on any 752 | author or copyright holder as a result of your choosing to follow a 753 | later version. 754 | 755 | 15. Disclaimer of Warranty. 756 | 757 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 758 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 759 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 760 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 761 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 762 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 763 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 764 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 765 | 766 | 16. Limitation of Liability. 767 | 768 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 769 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 770 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 771 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 772 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 773 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 774 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 775 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 776 | SUCH DAMAGES. 777 | 778 | 17. Interpretation of Sections 15 and 16. 779 | 780 | If the disclaimer of warranty and limitation of liability provided 781 | above cannot be given local legal effect according to their terms, 782 | reviewing courts shall apply local law that most closely approximates 783 | an absolute waiver of all civil liability in connection with the 784 | Program, unless a warranty or assumption of liability accompanies a 785 | copy of the Program in return for a fee. 786 | 787 | END OF TERMS AND CONDITIONS 788 | 789 | How to Apply These Terms to Your New Programs 790 | 791 | If you develop a new program, and you want it to be of the greatest 792 | possible use to the public, the best way to achieve this is to make it 793 | free software which everyone can redistribute and change under these terms. 794 | 795 | To do so, attach the following notices to the program. It is safest 796 | to attach them to the start of each source file to most effectively 797 | state the exclusion of warranty; and each file should have at least 798 | the "copyright" line and a pointer to where the full notice is found. 799 | 800 | {one line to give the program's name and a brief idea of what it does.} 801 | Copyright (C) {year} {name of author} 802 | 803 | This program is free software: you can redistribute it and/or modify 804 | it under the terms of the GNU General Public License as published by 805 | the Free Software Foundation, either version 3 of the License, or 806 | (at your option) any later version. 807 | 808 | This program is distributed in the hope that it will be useful, 809 | but WITHOUT ANY WARRANTY; without even the implied warranty of 810 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 811 | GNU General Public License for more details. 812 | 813 | You should have received a copy of the GNU General Public License 814 | along with this program. If not, see . 815 | 816 | Also add information on how to contact you by electronic and paper mail. 817 | 818 | If the program does terminal interaction, make it output a short 819 | notice like this when it starts in an interactive mode: 820 | 821 | {project} Copyright (C) {year} {fullname} 822 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 823 | This is free software, and you are welcome to redistribute it 824 | under certain conditions; type `show c' for details. 825 | 826 | The hypothetical commands `show w' and `show c' should show the appropriate 827 | parts of the General Public License. Of course, your program's commands 828 | might be different; for a GUI interface, you would use an "about box". 829 | 830 | You should also get your employer (if you work as a programmer) or school, 831 | if any, to sign a "copyright disclaimer" for the program, if necessary. 832 | For more information on this, and how to apply and follow the GNU GPL, see 833 | . 834 | 835 | The GNU General Public License does not permit incorporating your program 836 | into proprietary programs. If your program is a subroutine library, you 837 | may consider it more useful to permit linking proprietary applications with 838 | the library. If this is what you want to do, use the GNU Lesser General 839 | Public License instead of this License. But first, please read 840 | . 841 | 842 | -------------------------------------------------------------------------------- /build.gradle: -------------------------------------------------------------------------------- 1 | plugins { 2 | id 'fabric-loom' version '1.0-SNAPSHOT' 3 | id 'maven-publish' 4 | } 5 | 6 | /* 7 | * Gets the version name from the latest Git tag 8 | */ 9 | // https://stackoverflow.com/questions/28498688/gradle-script-to-autoversion-and-include-the-commit-hash-in-android 10 | def getGitCommit = { -> 11 | def stdout = new ByteArrayOutputStream() 12 | exec { 13 | commandLine 'git', 'rev-parse', '--short', 'HEAD' 14 | standardOutput = stdout 15 | } 16 | return stdout.toString().trim() 17 | } 18 | 19 | sourceCompatibility = JavaVersion.VERSION_17 20 | targetCompatibility = JavaVersion.VERSION_17 21 | 22 | archivesBaseName = project.archives_base_name 23 | version = project.mod_version + "+fabric." + getGitCommit() 24 | group = project.maven_group 25 | 26 | dependencies { 27 | //to change the versions see the gradle.properties file 28 | minecraft "com.mojang:minecraft:${project.minecraft_version}" 29 | mappings loom.officialMojangMappings() 30 | modImplementation "net.fabricmc:fabric-loader:${project.loader_version}" 31 | 32 | 33 | // PSA: Some older mods, compiled on Loom 0.2.1, might have outdated Maven POMs. 34 | // You may need to force-disable transitiveness on them. 35 | } 36 | 37 | processResources { 38 | inputs.property "version", project.version 39 | 40 | filesMatching("fabric.mod.json") { 41 | expand "version": project.version 42 | } 43 | } 44 | 45 | // ensure that the encoding is set to UTF-8, no matter what the system default is 46 | // this fixes some edge cases with special characters not displaying correctly 47 | // see http://yodaconditions.net/blog/fix-for-java-file-encoding-problems-with-gradle.html 48 | tasks.withType(JavaCompile) { 49 | options.encoding = "UTF-8" 50 | } 51 | 52 | loom { 53 | accessWidenerPath = file("src/main/resources/lightbench.accesswidener") 54 | } 55 | 56 | // Loom will automatically attach sourcesJar to a RemapSourcesJar task and to the "build" task 57 | // if it is present. 58 | // If you remove this task, sources will not be generated. 59 | java { 60 | // Loom will automatically attach sourcesJar to a RemapSourcesJar task and to the "build" task 61 | // if it is present. 62 | // If you remove this line, sources will not be generated. 63 | withSourcesJar() 64 | } 65 | jar { 66 | from "LICENSE" 67 | } 68 | 69 | // configure the maven publication 70 | publishing { 71 | publications { 72 | mavenJava(MavenPublication) { 73 | // add all the jars that should be included when publishing to maven 74 | artifact(remapJar) { 75 | builtBy remapJar 76 | } 77 | artifact(sourcesJar) { 78 | builtBy remapSourcesJar 79 | } 80 | } 81 | } 82 | 83 | // select the repositories you want to publish to 84 | repositories { 85 | // uncomment to publish to the local maven 86 | // mavenLocal() 87 | } 88 | } 89 | -------------------------------------------------------------------------------- /gradle.properties: -------------------------------------------------------------------------------- 1 | # Done to increase the memory available to gradle. 2 | org.gradle.jvmargs=-Xmx2G 3 | org.gradle.daemon=false 4 | # Fabric Properties 5 | # check these on https://modmuss50.me/fabric.html 6 | minecraft_version=1.20-rc1 7 | yarn_mappings=1.20-rc1+build.2 8 | loader_version=0.14.21 9 | # Mod Properties 10 | mod_version=1.0.4 11 | maven_group=ca.spottedleaf.lightbench 12 | archives_base_name=lightbench 13 | 14 | -------------------------------------------------------------------------------- /gradle/wrapper/gradle-wrapper.jar: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/Spottedleaf/lightbench/35693014f3181473c7b5d16bb74e39bd47b1dc78/gradle/wrapper/gradle-wrapper.jar -------------------------------------------------------------------------------- /gradle/wrapper/gradle-wrapper.properties: -------------------------------------------------------------------------------- 1 | distributionBase=GRADLE_USER_HOME 2 | distributionPath=wrapper/dists 3 | distributionUrl=https\://services.gradle.org/distributions/gradle-7.5.1-bin.zip 4 | zipStoreBase=GRADLE_USER_HOME 5 | zipStorePath=wrapper/dists 6 | -------------------------------------------------------------------------------- /gradlew: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | 3 | # 4 | # Copyright © 2015-2021 the original authors. 5 | # 6 | # Licensed under the Apache License, Version 2.0 (the "License");
