By contrast, 15 | the GNU General Public License is intended to guarantee your freedom to 16 | share and change all versions of a program--to make sure it remains free 17 | software for all its users. We, the Free Software Foundation, use the 18 | GNU General Public License for most of our software; it applies also to 19 | any other work released this way by its authors. You can apply it to 20 | your programs, too. 21 | 22 | When we speak of free software, we are referring to freedom, not 23 | price. Our General Public Licenses are designed to make sure that you 24 | have the freedom to distribute copies of free software (and charge for 25 | them if you wish), that you receive source code or can get it if you 26 | want it, that you can change the software or use pieces of it in new 27 | free programs, and that you know you can do these things. 28 | 29 | To protect your rights, we need to prevent others from denying you 30 | these rights or asking you to surrender the rights. Therefore, you have 31 | certain responsibilities if you distribute copies of the software, or if 32 | you modify it: responsibilities to respect the freedom of others. 33 | 34 | For example, if you distribute copies of such a program, whether 35 | gratis or for a fee, you must pass on to the recipients the same 36 | freedoms that you received. You must make sure that they, too, receive 37 | or can get the source code. And you must show them these terms so they 38 | know their rights. 39 | 40 | Developers that use the GNU GPL protect your rights with two steps: 41 | (1) assert copyright on the software, and (2) offer you this License 42 | giving you legal permission to copy, distribute and/or modify it. 43 | 44 | For the developers' and authors' protection, the GPL clearly explains 45 | that there is no warranty for this free software. For both users' and 46 | authors' sake, the GPL requires that modified versions be marked as 47 | changed, so that their problems will not be attributed erroneously to 48 | authors of previous versions. 49 | 50 | Some devices are designed to deny users access to install or run 51 | modified versions of the software inside them, although the manufacturer 52 | can do so. This is fundamentally incompatible with the aim of 53 | protecting users' freedom to change the software. The systematic 54 | pattern of such abuse occurs in the area of products for individuals to 55 | use, which is precisely where it is most unacceptable. Therefore, we 56 | have designed this version of the GPL to prohibit the practice for those 57 | products. If such problems arise substantially in other domains, we 58 | stand ready to extend this provision to those domains in future versions 59 | of the GPL, as needed to protect the freedom of users. 60 | 61 | Finally, every program is threatened constantly by software patents. 62 | States should not allow patents to restrict development and use of 63 | software on general-purpose computers, but in those that do, we wish to 64 | avoid the special danger that patents applied to a free program could 65 | make it effectively proprietary. To prevent this, the GPL assures that 66 | patents cannot be used to render the program non-free. 67 | 68 | The precise terms and conditions for copying, distribution and 69 | modification follow. 70 | 71 | TERMS AND CONDITIONS 72 | 73 | 0. Definitions. 74 | 75 | "This License" refers to version 3 of the GNU General Public License. 76 | 77 | "Copyright" also means copyright-like laws that apply to other kinds of 78 | works, such as semiconductor masks. 79 | 80 | "The Program" refers to any copyrightable work licensed under this 81 | License. Each licensee is addressed as "you". "Licensees" and 82 | "recipients" may be individuals or organizations. 83 | 84 | To "modify" a work means to copy from or adapt all or part of the work 85 | in a fashion requiring copyright permission, other than the making of an 86 | exact copy. The resulting work is called a "modified version" of the 87 | earlier work or a work "based on" the earlier work. 88 | 89 | A "covered work" means either the unmodified Program or a work based 90 | on the Program. 91 | 92 | To "propagate" a work means to do anything with it that, without 93 | permission, would make you directly or secondarily liable for 94 | infringement under applicable copyright law, except executing it on a 95 | computer or modifying a private copy. Propagation includes copying, 96 | distribution (with or without modification), making available to the 97 | public, and in some countries other activities as well. 98 | 99 | To "convey" a work means any kind of propagation that enables other 100 | parties to make or receive copies. Mere interaction with a user through 101 | a computer network, with no transfer of a copy, is not conveying. 102 | 103 | An interactive user interface displays "Appropriate Legal Notices" 104 | to the extent that it includes a convenient and prominently visible 105 | feature that (1) displays an appropriate copyright notice, and (2) 106 | tells the user that there is no warranty for the work (except to the 107 | extent that warranties are provided), that licensees may convey the 108 | work under this License, and how to view a copy of this License. If 109 | the interface presents a list of user commands or options, such as a 110 | menu, a prominent item in the list meets this criterion. 111 | 112 | 1. Source Code. 113 | 114 | The "source code" for a work means the preferred form of the work 115 | for making modifications to it. "Object code" means any non-source 116 | form of a work. 117 | 118 | A "Standard Interface" means an interface that either is an official 119 | standard defined by a recognized standards body, or, in the case of 120 | interfaces specified for a particular programming language, one that 121 | is widely used among developers working in that language. 122 | 123 | The "System Libraries" of an executable work include anything, other 124 | than the work as a whole, that (a) is included in the normal form of 125 | packaging a Major Component, but which is not part of that Major 126 | Component, and (b) serves only to enable use of the work with that 127 | Major Component, or to implement a Standard Interface for which an 128 | implementation is available to the public in source code form. A 129 | "Major Component", in this context, means a major essential component 130 | (kernel, window system, and so on) of the specific operating system 131 | (if any) on which the executable work runs, or a compiler used to 132 | produce the work, or an object code interpreter used to run it. 133 | 134 | The "Corresponding Source" for a work in object code form means all 135 | the source code needed to generate, install, and (for an executable 136 | work) run the object code and to modify the work, including scripts to 137 | control those activities. However, it does not include the work's 138 | System Libraries, or general-purpose tools or generally available free 139 | programs which are used unmodified in performing those activities but 140 | which are not part of the work. For example, Corresponding Source 141 | includes interface definition files associated with source files for 142 | the work, and the source code for shared libraries and dynamically 143 | linked subprograms that the work is specifically designed to require, 144 | such as by intimate data communication or control flow between those 145 | subprograms and other parts of the work. 146 | 147 | The Corresponding Source need not include anything that users 148 | can regenerate automatically from other parts of the Corresponding 149 | Source. 150 | 151 | The Corresponding Source for a work in source code form is that 152 | same work. 153 | 154 | 2. Basic Permissions. 155 | 156 | All rights granted under this License are granted for the term of 157 | copyright on the Program, and are irrevocable provided the stated 158 | conditions are met. This License explicitly affirms your unlimited 159 | permission to run the unmodified Program. The output from running a 160 | covered work is covered by this License only if the output, given its 161 | content, constitutes a covered work. This License acknowledges your 162 | rights of fair use or other equivalent, as provided by copyright law. 163 | 164 | You may make, run and propagate covered works that you do not 165 | convey, without conditions so long as your license otherwise remains 166 | in force. You may convey covered works to others for the sole purpose 167 | of having them make modifications exclusively for you, or provide you 168 | with facilities for running those works, provided that you comply with 169 | the terms of this License in conveying all material for which you do 170 | not control copyright. Those thus making or running the covered works 171 | for you must do so exclusively on your behalf, under your direction 172 | and control, on terms that prohibit them from making any copies of 173 | your copyrighted material outside their relationship with you. 174 | 175 | Conveying under any other circumstances is permitted solely under 176 | the conditions stated below. Sublicensing is not allowed; section 10 177 | makes it unnecessary. 178 | 179 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 180 | 181 | No covered work shall be deemed part of an effective technological 182 | measure under any applicable law fulfilling obligations under article 183 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or 184 | similar laws prohibiting or restricting circumvention of such 185 | measures. 186 | 187 | When you convey a covered work, you waive any legal power to forbid 188 | circumvention of technological measures to the extent such circumvention 189 | is effected by exercising rights under this License with respect to 190 | the covered work, and you disclaim any intention to limit operation or 191 | modification of the work as a means of enforcing, against the work's 192 | users, your or third parties' legal rights to forbid circumvention of 193 | technological measures. 194 | 195 | 4. Conveying Verbatim Copies. 196 | 197 | You may convey verbatim copies of the Program's source code as you 198 | receive it, in any medium, provided that you conspicuously and 199 | appropriately publish on each copy an appropriate copyright notice; 200 | keep intact all notices stating that this License and any 201 | non-permissive terms added in accord with section 7 apply to the code; 202 | keep intact all notices of the absence of any warranty; and give all 203 | recipients a copy of this License along with the Program. 204 | 205 | You may charge any price or no price for each copy that you convey, 206 | and you may offer support or warranty protection for a fee. 207 | 208 | 5. Conveying Modified Source Versions. 209 | 210 | You may convey a work based on the Program, or the modifications to 211 | produce it from the Program, in the form of source code under the 212 | terms of section 4, provided that you also meet all of these conditions: 213 | 214 | a) The work must carry prominent notices stating that you modified 215 | it, and giving a relevant date. 216 | 217 | b) The work must carry prominent notices stating that it is 218 | released under this License and any conditions added under section 219 | 7. This requirement modifies the requirement in section 4 to 220 | "keep intact all notices". 221 | 222 | c) You must license the entire work, as a whole, under this 223 | License to anyone who comes into possession of a copy. This 224 | License will therefore apply, along with any applicable section 7 225 | additional terms, to the whole of the work, and all its parts, 226 | regardless of how they are packaged. This License gives no 227 | permission to license the work in any other way, but it does not 228 | invalidate such permission if you have separately received it. 229 | 230 | d) If the work has interactive user interfaces, each must display 231 | Appropriate Legal Notices; however, if the Program has interactive 232 | interfaces that do not display Appropriate Legal Notices, your 233 | work need not make them do so. 234 | 235 | A compilation of a covered work with other separate and independent 236 | works, which are not by their nature extensions of the covered work, 237 | and which are not combined with it such as to form a larger program, 238 | in or on a volume of a storage or distribution medium, is called an 239 | "aggregate" if the compilation and its resulting copyright are not 240 | used to limit the access or legal rights of the compilation's users 241 | beyond what the individual works permit. Inclusion of a covered work 242 | in an aggregate does not cause this License to apply to the other 243 | parts of the aggregate. 244 | 245 | 6. Conveying Non-Source Forms. 246 | 247 | You may convey a covered work in object code form under the terms 248 | of sections 4 and 5, provided that you also convey the 249 | machine-readable Corresponding Source under the terms of this License, 250 | in one of these ways: 251 | 252 | a) Convey the object code in, or embodied in, a physical product 253 | (including a physical distribution medium), accompanied by the 254 | Corresponding Source fixed on a durable physical medium 255 | customarily used for software interchange. 256 | 257 | b) Convey the object code in, or embodied in, a physical product 258 | (including a physical distribution medium), accompanied by a 259 | written offer, valid for at least three years and valid for as 260 | long as you offer spare parts or customer support for that product 261 | model, to give anyone who possesses the object code either (1) a 262 | copy of the Corresponding Source for all the software in the 263 | product that is covered by this License, on a durable physical 264 | medium customarily used for software interchange, for a price no 265 | more than your reasonable cost of physically performing this 266 | conveying of source, or (2) access to copy the 267 | Corresponding Source from a network server at no charge. 268 | 269 | c) Convey individual copies of the object code with a copy of the 270 | written offer to provide the Corresponding Source. This 271 | alternative is allowed only occasionally and noncommercially, and 272 | only if you received the object code with such an offer, in accord 273 | with subsection 6b. 274 | 275 | d) Convey the object code by offering access from a designated 276 | place (gratis or for a charge), and offer equivalent access to the 277 | Corresponding Source in the same way through the same place at no 278 | further charge. You need not require recipients to copy the 279 | Corresponding Source along with the object code. If the place to 280 | copy the object code is a network server, the Corresponding Source 281 | may be on a different server (operated by you or a third party) 282 | that supports equivalent copying facilities, provided you maintain 283 | clear directions next to the object code saying where to find the 284 | Corresponding Source. Regardless of what server hosts the 285 | Corresponding Source, you remain obligated to ensure that it is 286 | available for as long as needed to satisfy these requirements. 287 | 288 | e) Convey the object code using peer-to-peer transmission, provided 289 | you inform other peers where the object code and Corresponding 290 | Source of the work are being offered to the general public at no 291 | charge under subsection 6d. 292 | 293 | A separable portion of the object code, whose source code is excluded 294 | from the Corresponding Source as a System Library, need not be 295 | included in conveying the object code work. 296 | 297 | A "User Product" is either (1) a "consumer product", which means any 298 | tangible personal property which is normally used for personal, family, 299 | or household purposes, or (2) anything designed or sold for incorporation 300 | into a dwelling. In determining whether a product is a consumer product, 301 | doubtful cases shall be resolved in favor of coverage. For a particular 302 | product received by a particular user, "normally used" refers to a 303 | typical or common use of that class of product, regardless of the status 304 | of the particular user or of the way in which the particular user 305 | actually uses, or expects or is expected to use, the product. A product 306 | is a consumer product regardless of whether the product has substantial 307 | commercial, industrial or non-consumer uses, unless such uses represent 308 | the only significant mode of use of the product. 309 | 310 | "Installation Information" for a User Product means any methods, 311 | procedures, authorization keys, or other information required to install 312 | and execute modified versions of a covered work in that User Product from 313 | a modified version of its Corresponding Source. The information must 314 | suffice to ensure that the continued functioning of the modified object 315 | code is in no case prevented or interfered with solely because 316 | modification has been made. 317 | 318 | If you convey an object code work under this section in, or with, or 319 | specifically for use in, a User Product, and the conveying occurs as 320 | part of a transaction in which the right of possession and use of the 321 | User Product is transferred to the recipient in perpetuity or for a 322 | fixed term (regardless of how the transaction is characterized), the 323 | Corresponding Source conveyed under this section must be accompanied 324 | by the Installation Information. But this requirement does not apply 325 | if neither you nor any third party retains the ability to install 326 | modified object code on the User Product (for example, the work has 327 | been installed in ROM). 328 | 329 | The requirement to provide Installation Information does not include a 330 | requirement to continue to provide support service, warranty, or updates 331 | for a work that has been modified or installed by the recipient, or for 332 | the User Product in which it has been modified or installed. Access to a 333 | network may be denied when the modification itself materially and 334 | adversely affects the operation of the network or violates the rules and 335 | protocols for communication across the network. 336 | 337 | Corresponding Source conveyed, and Installation Information provided, 338 | in accord with this section must be in a format that is publicly 339 | documented (and with an implementation available to the public in 340 | source code form), and must require no special password or key for 341 | unpacking, reading or copying. 342 | 343 | 7. Additional Terms. 344 | 345 | "Additional permissions" are terms that supplement the terms of this 346 | License by making exceptions from one or more of its conditions. 347 | Additional permissions that are applicable to the entire Program shall 348 | be treated as though they were included in this License, to the extent 349 | that they are valid under applicable law. If additional permissions 350 | apply only to part of the Program, that part may be used separately 351 | under those permissions, but the entire Program remains governed by 352 | this License without regard to the additional permissions. 353 | 354 | When you convey a copy of a covered work, you may at your option 355 | remove any additional permissions from that copy, or from any part of 356 | it. (Additional permissions may be written to require their own 357 | removal in certain cases when you modify the work.) You may place 358 | additional permissions on material, added by you to a covered work, 359 | for which you have or can give appropriate copyright permission. 360 | 361 | Notwithstanding any other provision of this License, for material you 362 | add to a covered work, you may (if authorized by the copyright holders of 363 | that material) supplement the terms of this License with terms: 364 | 365 | a) Disclaiming warranty or limiting liability differently from the 366 | terms of sections 15 and 16 of this License; or 367 | 368 | b) Requiring preservation of specified reasonable legal notices or 369 | author attributions in that material or in the Appropriate Legal 370 | Notices displayed by works containing it; or 371 | 372 | c) Prohibiting misrepresentation of the origin of that material, or 373 | requiring that modified versions of such material be marked in 374 | reasonable ways as different from the original version; or 375 | 376 | d) Limiting the use for publicity purposes of names of licensors or 377 | authors of the material; or 378 | 379 | e) Declining to grant rights under trademark law for use of some 380 | trade names, trademarks, or service marks; or 381 | 382 | f) Requiring indemnification of licensors and authors of that 383 | material by anyone who conveys the material (or modified versions of 384 | it) with contractual assumptions of liability to the recipient, for 385 | any liability that these contractual assumptions directly impose on 386 | those licensors and authors. 387 | 388 | All other non-permissive additional terms are considered "further 389 | restrictions" within the meaning of section 10. If the Program as you 390 | received it, or any part of it, contains a notice stating that it is 391 | governed by this License along with a term that is a further 392 | restriction, you may remove that term. If a license document contains 393 | a further restriction but permits relicensing or conveying under this 394 | License, you may add to a covered work material governed by the terms 395 | of that license document, provided that the further restriction does 396 | not survive such relicensing or conveying. 397 | 398 | If you add terms to a covered work in accord with this section, you 399 | must place, in the relevant source files, a statement of the 400 | additional terms that apply to those files, or a notice indicating 401 | where to find the applicable terms. 402 | 403 | Additional terms, permissive or non-permissive, may be stated in the 404 | form of a separately written license, or stated as exceptions; 405 | the above requirements apply either way. 406 | 407 | 8. Termination. 408 | 409 | You may not propagate or modify a covered work except as expressly 410 | provided under this License. Any attempt otherwise to propagate or 411 | modify it is void, and will automatically terminate your rights under 412 | this License (including any patent licenses granted under the third 413 | paragraph of section 11). 414 | 415 | However, if you cease all violation of this License, then your 416 | license from a particular copyright holder is reinstated (a) 417 | provisionally, unless and until the copyright holder explicitly and 418 | finally terminates your license, and (b) permanently, if the copyright 419 | holder fails to notify you of the violation by some reasonable means 420 | prior to 60 days after the cessation. 421 | 422 | Moreover, your license from a particular copyright holder is 423 | reinstated permanently if the copyright holder notifies you of the 424 | violation by some reasonable means, this is the first time you have 425 | received notice of violation of this License (for any work) from that 426 | copyright holder, and you cure the violation prior to 30 days after 427 | your receipt of the notice. 428 | 429 | Termination of your rights under this section does not terminate the 430 | licenses of parties who have received copies or rights from you under 431 | this License. If your rights have been terminated and not permanently 432 | reinstated, you do not qualify to receive new licenses for the same 433 | material under section 10. 434 | 435 | 9. Acceptance Not Required for Having Copies. 436 | 437 | You are not required to accept this License in order to receive or 438 | run a copy of the Program. Ancillary propagation of a covered work 439 | occurring solely as a consequence of using peer-to-peer transmission 440 | to receive a copy likewise does not require acceptance. However, 441 | nothing other than this License grants you permission to propagate or 442 | modify any covered work. These actions infringe copyright if you do 443 | not accept this License. Therefore, by modifying or propagating a 444 | covered work, you indicate your acceptance of this License to do so. 445 | 446 | 10. Automatic Licensing of Downstream Recipients. 447 | 448 | Each time you convey a covered work, the recipient automatically 449 | receives a license from the original licensors, to run, modify and 450 | propagate that work, subject to this License. You are not responsible 451 | for enforcing compliance by third parties with this License. 452 | 453 | An "entity transaction" is a transaction transferring control of an 454 | organization, or substantially all assets of one, or subdividing an 455 | organization, or merging organizations. If propagation of a covered 456 | work results from an entity transaction, each party to that 457 | transaction who receives a copy of the work also receives whatever 458 | licenses to the work the party's predecessor in interest had or could 459 | give under the previous paragraph, plus a right to possession of the 460 | Corresponding Source of the work from the predecessor in interest, if 461 | the predecessor has it or can get it with reasonable efforts. 462 | 463 | You may not impose any further restrictions on the exercise of the 464 | rights granted or affirmed under this License. For example, you may 465 | not impose a license fee, royalty, or other charge for exercise of 466 | rights granted under this License, and you may not initiate litigation 467 | (including a cross-claim or counterclaim in a lawsuit) alleging that 468 | any patent claim is infringed by making, using, selling, offering for 469 | sale, or importing the Program or any portion of it. 470 | 471 | 11. Patents. 472 | 473 | A "contributor" is a copyright holder who authorizes use under this 474 | License of the Program or a work on which the Program is based. The 475 | work thus licensed is called the contributor's "contributor version". 476 | 477 | A contributor's "essential patent claims" are all patent claims 478 | owned or controlled by the contributor, whether already acquired or 479 | hereafter acquired, that would be infringed by some manner, permitted 480 | by this License, of making, using, or selling its contributor version, 481 | but do not include claims that would be infringed only as a 482 | consequence of further modification of the contributor version. For 483 | purposes of this definition, "control" includes the right to grant 484 | patent sublicenses in a manner consistent with the requirements of 485 | this License. 486 | 487 | Each contributor grants you a non-exclusive, worldwide, royalty-free 488 | patent license under the contributor's essential patent claims, to 489 | make, use, sell, offer for sale, import and otherwise run, modify and 490 | propagate the contents of its contributor version. 491 | 492 | In the following three paragraphs, a "patent license" is any express 493 | agreement or commitment, however denominated, not to enforce a patent 494 | (such as an express permission to practice a patent or covenant not to 495 | sue for patent infringement). To "grant" such a patent license to a 496 | party means to make such an agreement or commitment not to enforce a 497 | patent against the party. 498 | 499 | If you convey a covered work, knowingly relying on a patent license, 500 | and the Corresponding Source of the work is not available for anyone 501 | to copy, free of charge and under the terms of this License, through a 502 | publicly available network server or other readily accessible means, 503 | then you must either (1) cause the Corresponding Source to be so 504 | available, or (2) arrange to deprive yourself of the benefit of the 505 | patent license for this particular work, or (3) arrange, in a manner 506 | consistent with the requirements of this License, to extend the patent 507 | license to downstream recipients. "Knowingly relying" means you have 508 | actual knowledge that, but for the patent license, your conveying the 509 | covered work in a country, or your recipient's use of the covered work 510 | in a country, would infringe one or more identifiable patents in that 511 | country that you have reason to believe are valid. 512 | 513 | If, pursuant to or in connection with a single transaction or 514 | arrangement, you convey, or propagate by procuring conveyance of, a 515 | covered work, and grant a patent license to some of the parties 516 | receiving the covered work authorizing them to use, propagate, modify 517 | or convey a specific copy of the covered work, then the patent license 518 | you grant is automatically extended to all recipients of the covered 519 | work and works based on it. 520 | 521 | A patent license is "discriminatory" if it does not include within 522 | the scope of its coverage, prohibits the exercise of, or is 523 | conditioned on the non-exercise of one or more of the rights that are 524 | specifically granted under this License. You may not convey a covered 525 | work if you are a party to an arrangement with a third party that is 526 | in the business of distributing software, under which you make payment 527 | to the third party based on the extent of your activity of conveying 528 | the work, and under which the third party grants, to any of the 529 | parties who would receive the covered work from you, a discriminatory 530 | patent license (a) in connection with copies of the covered work 531 | conveyed by you (or copies made from those copies), or (b) primarily 532 | for and in connection with specific products or compilations that 533 | contain the covered work, unless you entered into that arrangement, 534 | or that patent license was granted, prior to 28 March 2007. 535 | 536 | Nothing in this License shall be construed as excluding or limiting 537 | any implied license or other defenses to infringement that may 538 | otherwise be available to you under applicable patent law. 539 | 540 | 12. No Surrender of Others' Freedom. 541 | 542 | If conditions are imposed on you (whether by court order, agreement or 543 | otherwise) that contradict the conditions of this License, they do not 544 | excuse you from the conditions of this License. If you cannot convey a 545 | covered work so as to satisfy simultaneously your obligations under this 546 | License and any other pertinent obligations, then as a consequence you may 547 | not convey it at all. For example, if you agree to terms that obligate you 548 | to collect a royalty for further conveying from those to whom you convey 549 | the Program, the only way you could satisfy both those terms and this 550 | License would be to refrain entirely from conveying the Program. 551 | 552 | 13. Use with the GNU Affero General Public License. 553 | 554 | Notwithstanding any other provision of this License, you have 555 | permission to link or combine any covered work with a work licensed 556 | under version 3 of the GNU Affero General Public License into a single 557 | combined work, and to convey the resulting work. The terms of this 558 | License will continue to apply to the part which is the covered work, 559 | but the special requirements of the GNU Affero General Public License, 560 | section 13, concerning interaction through a network will apply to the 561 | combination as such. 562 | 563 | 14. Revised Versions of this License. 564 | 565 | The Free Software Foundation may publish revised and/or new versions of 566 | the GNU General Public License from time to time. Such new versions will 567 | be similar in spirit to the present version, but may differ in detail to 568 | address new problems or concerns. 569 | 570 | Each version is given a distinguishing version number. If the 571 | Program specifies that a certain numbered version of the GNU General 572 | Public License "or any later version" applies to it, you have the 573 | option of following the terms and conditions either of that numbered 574 | version or of any later version published by the Free Software 575 | Foundation. If the Program does not specify a version number of the 576 | GNU General Public License, you may choose any version ever published 577 | by the Free Software Foundation. 578 | 579 | If the Program specifies that a proxy can decide which future 580 | versions of the GNU General Public License can be used, that proxy's 581 | public statement of acceptance of a version permanently authorizes you 582 | to choose that version for the Program. 583 | 584 | Later license versions may give you additional or different 585 | permissions. However, no additional obligations are imposed on any 586 | author or copyright holder as a result of your choosing to follow a 587 | later version. 588 | 589 | 15. Disclaimer of Warranty. 590 | 591 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 592 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 593 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 594 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 595 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 596 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 597 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 598 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 599 | 600 | 16. Limitation of Liability. 601 | 602 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 603 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 604 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 605 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 606 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 607 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 608 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 609 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 610 | SUCH DAMAGES. 611 | 612 | 17. Interpretation of Sections 15 and 16. 613 | 614 | If the disclaimer of warranty and limitation of liability provided 615 | above cannot be given local legal effect according to their terms, 616 | reviewing courts shall apply local law that most closely approximates 617 | an absolute waiver of all civil liability in connection with the 618 | Program, unless a warranty or assumption of liability accompanies a 619 | copy of the Program in return for a fee. 620 | 621 | END OF TERMS AND CONDITIONS 622 | 623 | How to Apply These Terms to Your New Programs 624 | 625 | If you develop a new program, and you want it to be of the greatest 626 | possible use to the public, the best way to achieve this is to make it 627 | free software which everyone can redistribute and change under these terms. 628 | 629 | To do so, attach the following notices to the program. It is safest 630 | to attach them to the start of each source file to most effectively 631 | state the exclusion of warranty; and each file should have at least 632 | the "copyright" line and a pointer to where the full notice is found. 633 | 634 | 635 | Copyright (C) 636 | 637 | This program is free software: you can redistribute it and/or modify 638 | it under the terms of the GNU General Public License as published by 639 | the Free Software Foundation, either version 3 of the License, or 640 | (at your option) any later version. 641 | 642 | This program is distributed in the hope that it will be useful, 643 | but WITHOUT ANY WARRANTY; without even the implied warranty of 644 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 645 | GNU General Public License for more details. 646 | 647 | You should have received a copy of the GNU General Public License 648 | along with this program. If not, see . 649 | 650 | Also add information on how to contact you by electronic and paper mail. 651 | 652 | If the program does terminal interaction, make it output a short 653 | notice like this when it starts in an interactive mode: 654 | 655 | Copyright (C) 656 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 657 | This is free software, and you are welcome to redistribute it 658 | under certain conditions; type `show c' for details. 659 | 660 | The hypothetical commands `show w' and `show c' should show the appropriate 661 | parts of the General Public License. Of course, your program's commands 662 | might be different; for a GUI interface, you would use an "about box". 663 | 664 | You should also get your employer (if you work as a programmer) or school, 665 | if any, to sign a "copyright disclaimer" for the program, if necessary. 666 | For more information on this, and how to apply and follow the GNU GPL, see 667 | . 668 | 669 | The GNU General Public License does not permit incorporating your program 670 | into proprietary programs. If your program is a subroutine library, you 671 | may consider it more useful to permit linking proprietary applications with 672 | the library. If this is what you want to do, use the GNU Lesser General 673 | Public License instead of this License. But first, please read 674 | . 675 | -------------------------------------------------------------------------------- /ChangeLog: -------------------------------------------------------------------------------- 1 | See the Git log. 2 | -------------------------------------------------------------------------------- /INSTALL: -------------------------------------------------------------------------------- 1 | Installation Instructions 2 | ************************* 3 | 4 | Copyright (C) 1994-1996, 1999-2002, 2004-2017, 2020-2021 Free 5 | Software Foundation, Inc. 6 | 7 | Copying and distribution of this file, with or without modification, 8 | are permitted in any medium without royalty provided the copyright 9 | notice and this notice are preserved. This file is offered as-is, 10 | without warranty of any kind. 11 | 12 | Basic Installation 13 | ================== 14 | 15 | Briefly, the shell command './configure && make && make install' 16 | should configure, build, and install this package. The following 17 | more-detailed instructions are generic; see the 'README' file for 18 | instructions specific to this package. Some packages provide this 19 | 'INSTALL' file but do not implement all of the features documented 20 | below. The lack of an optional feature in a given package is not 21 | necessarily a bug. More recommendations for GNU packages can be found 22 | in *note Makefile Conventions: (standards)Makefile Conventions. 23 | 24 | The 'configure' shell script attempts to guess correct values for 25 | various system-dependent variables used during compilation. It uses 26 | those values to create a 'Makefile' in each directory of the package. 27 | It may also create one or more '.h' files containing system-dependent 28 | definitions. Finally, it creates a shell script 'config.status' that 29 | you can run in the future to recreate the current configuration, and a 30 | file 'config.log' containing compiler output (useful mainly for 31 | debugging 'configure'). 32 | 33 | It can also use an optional file (typically called 'config.cache' and 34 | enabled with '--cache-file=config.cache' or simply '-C') that saves the 35 | results of its tests to speed up reconfiguring. Caching is disabled by 36 | default to prevent problems with accidental use of stale cache files. 37 | 38 | If you need to do unusual things to compile the package, please try 39 | to figure out how 'configure' could check whether to do them, and mail 40 | diffs or instructions to the address given in the 'README' so they can 41 | be considered for the next release. If you are using the cache, and at 42 | some point 'config.cache' contains results you don't want to keep, you 43 | may remove or edit it. 44 | 45 | The file 'configure.ac' (or 'configure.in') is used to create 46 | 'configure' by a program called 'autoconf'. You need 'configure.ac' if 47 | you want to change it or regenerate 'configure' using a newer version of 48 | 'autoconf'. 49 | 50 | The simplest way to compile this package is: 51 | 52 | 1. 'cd' to the directory containing the package's source code and type 53 | './configure' to configure the package for your system. 54 | 55 | Running 'configure' might take a while. While running, it prints 56 | some messages telling which features it is checking for. 57 | 58 | 2. Type 'make' to compile the package. 59 | 60 | 3. Optionally, type 'make check' to run any self-tests that come with 61 | the package, generally using the just-built uninstalled binaries. 62 | 63 | 4. Type 'make install' to install the programs and any data files and 64 | documentation. When installing into a prefix owned by root, it is 65 | recommended that the package be configured and built as a regular 66 | user, and only the 'make install' phase executed with root 67 | privileges. 68 | 69 | 5. Optionally, type 'make installcheck' to repeat any self-tests, but 70 | this time using the binaries in their final installed location. 71 | This target does not install anything. Running this target as a 72 | regular user, particularly if the prior 'make install' required 73 | root privileges, verifies that the installation completed 74 | correctly. 75 | 76 | 6. You can remove the program binaries and object files from the 77 | source code directory by typing 'make clean'. To also remove the 78 | files that 'configure' created (so you can compile the package for 79 | a different kind of computer), type 'make distclean'. There is 80 | also a 'make maintainer-clean' target, but that is intended mainly 81 | for the package's developers. If you use it, you may have to get 82 | all sorts of other programs in order to regenerate files that came 83 | with the distribution. 84 | 85 | 7. Often, you can also type 'make uninstall' to remove the installed 86 | files again. In practice, not all packages have tested that 87 | uninstallation works correctly, even though it is required by the 88 | GNU Coding Standards. 89 | 90 | 8. Some packages, particularly those that use Automake, provide 'make 91 | distcheck', which can by used by developers to test that all other 92 | targets like 'make install' and 'make uninstall' work correctly. 93 | This target is generally not run by end users. 94 | 95 | Compilers and Options 96 | ===================== 97 | 98 | Some systems require unusual options for compilation or linking that 99 | the 'configure' script does not know about. Run './configure --help' 100 | for details on some of the pertinent environment variables. 101 | 102 | You can give 'configure' initial values for configuration parameters 103 | by setting variables in the command line or in the environment. Here is 104 | an example: 105 | 106 | ./configure CC=c99 CFLAGS=-g LIBS=-lposix 107 | 108 | *Note Defining Variables::, for more details. 109 | 110 | Compiling For Multiple Architectures 111 | ==================================== 112 | 113 | You can compile the package for more than one kind of computer at the 114 | same time, by placing the object files for each architecture in their 115 | own directory. To do this, you can use GNU 'make'. 'cd' to the 116 | directory where you want the object files and executables to go and run 117 | the 'configure' script. 'configure' automatically checks for the source 118 | code in the directory that 'configure' is in and in '..'. This is known 119 | as a "VPATH" build. 120 | 121 | With a non-GNU 'make', it is safer to compile the package for one 122 | architecture at a time in the source code directory. After you have 123 | installed the package for one architecture, use 'make distclean' before 124 | reconfiguring for another architecture. 125 | 126 | On MacOS X 10.5 and later systems, you can create libraries and 127 | executables that work on multiple system types--known as "fat" or 128 | "universal" binaries--by specifying multiple '-arch' options to the 129 | compiler but only a single '-arch' option to the preprocessor. Like 130 | this: 131 | 132 | ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ 133 | CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ 134 | CPP="gcc -E" CXXCPP="g++ -E" 135 | 136 | This is not guaranteed to produce working output in all cases, you 137 | may have to build one architecture at a time and combine the results 138 | using the 'lipo' tool if you have problems. 139 | 140 | Installation Names 141 | ================== 142 | 143 | By default, 'make install' installs the package's commands under 144 | '/usr/local/bin', include files under '/usr/local/include', etc. You 145 | can specify an installation prefix other than '/usr/local' by giving 146 | 'configure' the option '--prefix=PREFIX', where PREFIX must be an 147 | absolute file name. 148 | 149 | You can specify separate installation prefixes for 150 | architecture-specific files and architecture-independent files. If you 151 | pass the option '--exec-prefix=PREFIX' to 'configure', the package uses 152 | PREFIX as the prefix for installing programs and libraries. 153 | Documentation and other data files still use the regular prefix. 154 | 155 | In addition, if you use an unusual directory layout you can give 156 | options like '--bindir=DIR' to specify different values for particular 157 | kinds of files. Run 'configure --help' for a list of the directories 158 | you can set and what kinds of files go in them. In general, the default 159 | for these options is expressed in terms of '${prefix}', so that 160 | specifying just '--prefix' will affect all of the other directory 161 | specifications that were not explicitly provided. 162 | 163 | The most portable way to affect installation locations is to pass the 164 | correct locations to 'configure'; however, many packages provide one or 165 | both of the following shortcuts of passing variable assignments to the 166 | 'make install' command line to change installation locations without 167 | having to reconfigure or recompile. 168 | 169 | The first method involves providing an override variable for each 170 | affected directory. For example, 'make install 171 | prefix=/alternate/directory' will choose an alternate location for all 172 | directory configuration variables that were expressed in terms of 173 | '${prefix}'. Any directories that were specified during 'configure', 174 | but not in terms of '${prefix}', must each be overridden at install time 175 | for the entire installation to be relocated. The approach of makefile 176 | variable overrides for each directory variable is required by the GNU 177 | Coding Standards, and ideally causes no recompilation. However, some 178 | platforms have known limitations with the semantics of shared libraries 179 | that end up requiring recompilation when using this method, particularly 180 | noticeable in packages that use GNU Libtool. 181 | 182 | The second method involves providing the 'DESTDIR' variable. For 183 | example, 'make install DESTDIR=/alternate/directory' will prepend 184 | '/alternate/directory' before all installation names. The approach of 185 | 'DESTDIR' overrides is not required by the GNU Coding Standards, and 186 | does not work on platforms that have drive letters. On the other hand, 187 | it does better at avoiding recompilation issues, and works well even 188 | when some directory options were not specified in terms of '${prefix}' 189 | at 'configure' time. 190 | 191 | Optional Features 192 | ================= 193 | 194 | If the package supports it, you can cause programs to be installed 195 | with an extra prefix or suffix on their names by giving 'configure' the 196 | option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. 197 | 198 | Some packages pay attention to '--enable-FEATURE' options to 199 | 'configure', where FEATURE indicates an optional part of the package. 200 | They may also pay attention to '--with-PACKAGE' options, where PACKAGE 201 | is something like 'gnu-as' or 'x' (for the X Window System). The 202 | 'README' should mention any '--enable-' and '--with-' options that the 203 | package recognizes. 204 | 205 | For packages that use the X Window System, 'configure' can usually 206 | find the X include and library files automatically, but if it doesn't, 207 | you can use the 'configure' options '--x-includes=DIR' and 208 | '--x-libraries=DIR' to specify their locations. 209 | 210 | Some packages offer the ability to configure how verbose the 211 | execution of 'make' will be. For these packages, running './configure 212 | --enable-silent-rules' sets the default to minimal output, which can be 213 | overridden with 'make V=1'; while running './configure 214 | --disable-silent-rules' sets the default to verbose, which can be 215 | overridden with 'make V=0'. 216 | 217 | Particular systems 218 | ================== 219 | 220 | On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC 221 | is not installed, it is recommended to use the following options in 222 | order to use an ANSI C compiler: 223 | 224 | ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" 225 | 226 | and if that doesn't work, install pre-built binaries of GCC for HP-UX. 227 | 228 | HP-UX 'make' updates targets which have the same timestamps as their 229 | prerequisites, which makes it generally unusable when shipped generated 230 | files such as 'configure' are involved. Use GNU 'make' instead. 231 | 232 | On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot 233 | parse its '' header file. The option '-nodtk' can be used as a 234 | workaround. If GNU CC is not installed, it is therefore recommended to 235 | try 236 | 237 | ./configure CC="cc" 238 | 239 | and if that doesn't work, try 240 | 241 | ./configure CC="cc -nodtk" 242 | 243 | On Solaris, don't put '/usr/ucb' early in your 'PATH'. This 244 | directory contains several dysfunctional programs; working variants of 245 | these programs are available in '/usr/bin'. So, if you need '/usr/ucb' 246 | in your 'PATH', put it _after_ '/usr/bin'. 247 | 248 | On Haiku, software installed for all users goes in '/boot/common', 249 | not '/usr/local'. It is recommended to use the following options: 250 | 251 | ./configure --prefix=/boot/common 252 | 253 | Specifying the System Type 254 | ========================== 255 | 256 | There may be some features 'configure' cannot figure out 257 | automatically, but needs to determine by the type of machine the package 258 | will run on. Usually, assuming the package is built to be run on the 259 | _same_ architectures, 'configure' can figure that out, but if it prints 260 | a message saying it cannot guess the machine type, give it the 261 | '--build=TYPE' option. TYPE can either be a short name for the system 262 | type, such as 'sun4', or a canonical name which has the form: 263 | 264 | CPU-COMPANY-SYSTEM 265 | 266 | where SYSTEM can have one of these forms: 267 | 268 | OS 269 | KERNEL-OS 270 | 271 | See the file 'config.sub' for the possible values of each field. If 272 | 'config.sub' isn't included in this package, then this package doesn't 273 | need to know the machine type. 274 | 275 | If you are _building_ compiler tools for cross-compiling, you should 276 | use the option '--target=TYPE' to select the type of system they will 277 | produce code for. 278 | 279 | If you want to _use_ a cross compiler, that generates code for a 280 | platform different from the build platform, you should specify the 281 | "host" platform (i.e., that on which the generated programs will 282 | eventually be run) with '--host=TYPE'. 283 | 284 | Sharing Defaults 285 | ================ 286 | 287 | If you want to set default values for 'configure' scripts to share, 288 | you can create a site shell script called 'config.site' that gives 289 | default values for variables like 'CC', 'cache_file', and 'prefix'. 290 | 'configure' looks for 'PREFIX/share/config.site' if it exists, then 291 | 'PREFIX/etc/config.site' if it exists. Or, you can set the 292 | 'CONFIG_SITE' environment variable to the location of the site script. 293 | A warning: not all 'configure' scripts look for a site script. 294 | 295 | Defining Variables 296 | ================== 297 | 298 | Variables not defined in a site shell script can be set in the 299 | environment passed to 'configure'. However, some packages may run 300 | configure again during the build, and the customized values of these 301 | variables may be lost. In order to avoid this problem, you should set 302 | them in the 'configure' command line, using 'VAR=value'. For example: 303 | 304 | ./configure CC=/usr/local2/bin/gcc 305 | 306 | causes the specified 'gcc' to be used as the C compiler (unless it is 307 | overridden in the site shell script). 308 | 309 | Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an 310 | Autoconf limitation. Until the limitation is lifted, you can use this 311 | workaround: 312 | 313 | CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash 314 | 315 | 'configure' Invocation 316 | ====================== 317 | 318 | 'configure' recognizes the following options to control how it 319 | operates. 320 | 321 | '--help' 322 | '-h' 323 | Print a summary of all of the options to 'configure', and exit. 324 | 325 | '--help=short' 326 | '--help=recursive' 327 | Print a summary of the options unique to this package's 328 | 'configure', and exit. The 'short' variant lists options used only 329 | in the top level, while the 'recursive' variant lists options also 330 | present in any nested packages. 331 | 332 | '--version' 333 | '-V' 334 | Print the version of Autoconf used to generate the 'configure' 335 | script, and exit. 336 | 337 | '--cache-file=FILE' 338 | Enable the cache: use and save the results of the tests in FILE, 339 | traditionally 'config.cache'. FILE defaults to '/dev/null' to 340 | disable caching. 341 | 342 | '--config-cache' 343 | '-C' 344 | Alias for '--cache-file=config.cache'. 345 | 346 | '--quiet' 347 | '--silent' 348 | '-q' 349 | Do not print messages saying which checks are being made.

Also add console-debug. 8 | 9 | - Removed special syntax to access JavaScript objects and added js-ref, 10 | js-set!, js-new and js-invoke. 11 | 12 | * Version 0.1.0 (Jan 21, 2022) 13 | 14 | - Very primitive JavaScript object method calls. 15 | 16 | - Create 'javascript language which actually decompiles from 'tree-il. So basically we do: 17 | compile(guilescript) -> 'tree-il -> decompile(tree-il) -> javascript. 18 | 19 | - Split function translation into its own file. 20 | 21 | - Fix ending statement semicolon issues. 22 | 23 | - Return statements should only be allowed inside functions. 24 | 25 | * Version 0.0.0 (Jan 17, 2022) 26 | 27 | - Initial release. 28 | -------------------------------------------------------------------------------- /README: -------------------------------------------------------------------------------- 1 | README.org -------------------------------------------------------------------------------- /README.org: -------------------------------------------------------------------------------- 1 | 2 | * What is GuileScript? 3 | 4 | [[https://github.com/aconchillo/guilescript/actions/workflows/guile2.2.yml][https://github.com/aconchillo/guilescript/actions/workflows/guile3.0.yml/badge.svg]] 5 | 6 | GuileScript is currently a toy compiler that aims to compile [[https://www.gnu.org/software/guile/][Guile]] to 7 | JavaScript. It currently doesn't do much, but it might in the future. 8 | 9 | * Why? 10 | 11 | Because, why not? [[https://www.gnu.org/software/guile/][Guile]] is actually a lot of fun and I just got jealous that 12 | people could do these sort of [[https://twitter.com/zaneshelby/status/1477988369154121734?s=20][cool things with ClojureScript]] and I couldn't with 13 | Guile. But thanks to GuileScript it is now with [[https://github.com/aconchillo/gas][gas]]. 14 | 15 | * How does it work? 16 | 17 | GuileScript leverages [[https://www.gnu.org/software/guile/manual/html_node/Compiler-Tower.html][Guile's Compiler Tower]]. It compiles Guile code into 18 | [[https://www.gnu.org/software/guile/manual/html_node/Tree_002dIL.html][Tree-IL]] and then compiles Tree-IL into JavaScript. 19 | 20 | Tree-IL is the first intermediate language (the main one actually being [[https://www.gnu.org/software/guile/manual/html_node/Continuation_002dPassing-Style.html][CPS]]) 21 | that Guile code is actually converted to, so the only thing that I needed to do 22 | is figure out how Tree-IL works plus get some inspiration from [[https://github.com/clojure/clojurescript/blob/v0.0/src/clj/clojure/cljs.clj][ClojureScript 23 | first commit]]. 24 | 25 | * How do I try it out? 26 | 27 | Clone the repository and run: 28 | 29 | #+BEGIN_EXAMPLE 30 | $ autoreconf -vif 31 | $ ./configure 32 | $ make 33 | $ sudo make install 34 | #+END_EXAMPLE 35 | 36 | If you are on macOS you can actually install GuileScript through [[https://github.com/aconchillo/homebrew-guile][Guile Homebrew]]: 37 | 38 | #+BEGIN_EXAMPLE 39 | $ brew install aconchillo/guile/guilescript 40 | #+END_EXAMPLE 41 | 42 | If everything builds and installs fine you can try to compile one of the 43 | provided examples (e.g. =examples/fibonacci.gs=): 44 | 45 | #+BEGIN_SRC scheme 46 | (define (fib n) 47 | (if (<= n 1) 48 | 1 49 | (+ (fib (- n 2)) (fib (- n 1))))) 50 | #+END_SRC 51 | 52 | #+BEGIN_EXAMPLE 53 | $ guilescript examples/fibonacci.gs 54 | #+END_EXAMPLE 55 | 56 | which in this case would generate something like: 57 | 58 | #+BEGIN_SRC javascript 59 | var fib = function fib(n) { 60 | return ((n<=1) ? 1 : (fib((n-2))+fib((n-1)))); 61 | }; 62 | #+END_SRC javascript 63 | 64 | * What's missing? 65 | 66 | Too many things, but just to name a few: 67 | 68 | - More types: maps, sets... 69 | 70 | - More vector and string functions. 71 | 72 | - Support formatting in logging functions. 73 | 74 | - Integration with Google's [[https://developers.google.com/closure/compiler][Closure Compiler]]. 75 | 76 | And even long term: 77 | 78 | - Modules. 79 | 80 | - NodeJS integration. 81 | 82 | * What's supported? 83 | 84 | ** Types 85 | 86 | | GuileScript | JavaScript | 87 | |-------------+------------| 88 | | #nil | null | 89 | |-------------+------------| 90 | | "guile" | "guile" | 91 | |-------------+------------| 92 | | 'guile | guile | 93 | |-------------+------------| 94 | | #t | true | 95 | |-------------+------------| 96 | | #f | false | 97 | |-------------+------------| 98 | | 234 | 234 | 99 | |-------------+------------| 100 | | 0.5 | 0.5 | 101 | |-------------+------------| 102 | | 1/2 | 0.5 | 103 | |-------------+------------| 104 | | #(1 2 3) | [1,2,3] | 105 | |-------------+------------| 106 | 107 | ** Strings 108 | 109 | | GuileScript | JavaScript | 110 | |---------------------+------------| 111 | | (string-length s) | s.length | 112 | |---------------------+------------| 113 | | (string-ref s i) | s[i] | 114 | |---------------------+------------| 115 | 116 | ** Vectors 117 | 118 | | GuileScript | JavaScript | 119 | |---------------------+------------| 120 | | (vector-length v) | v.length | 121 | |---------------------+------------| 122 | | (vector-ref v i) | v[i] | 123 | |---------------------+------------| 124 | | (vector-set! v i m) | v[i] = m | 125 | |---------------------+------------| 126 | 127 | ** Objects 128 | 129 | | GuileScript | JavaScript | 130 | |---------------------------------------+---------------------------| 131 | | (js-invoke obj 'method arg1 ... argN) | obj.method(arg1,...,argN) | 132 | |---------------------------------------+---------------------------| 133 | | (js-new "type" arg1 ... argN) | new type(arg1,...,argN) | 134 | |---------------------------------------+---------------------------| 135 | | (js-ref obj 'prop) | obj.prop | 136 | |---------------------------------------+---------------------------| 137 | | (js-set! obj 'prop value) | obj.prop = value | 138 | |---------------------------------------+---------------------------| 139 | 140 | Note that ~(js-set! obj prop value)~ is just a shortcut to ~(set!
