By contrast, the GNU General Public License is intended to +guarantee your freedom to share and change free software--to make sure the +software is free for all its users. This General Public License applies to most +of the Free Software Foundation's software and to any other program whose +authors commit to using it. (Some other Free Software Foundation software is +covered by the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + +When we speak of free software, we are referring to freedom, not price. Our +General Public Licenses are designed to make sure that you have the freedom to +distribute copies of free software (and charge for this service if you wish), +that you receive source code or can get it if you want it, that you can change +the software or use pieces of it in new free programs; and that you know you can +do these things. + +To protect your rights, we need to make restrictions that forbid anyone to deny +you these rights or to ask you to surrender the rights. These restrictions +translate to certain responsibilities for you if you distribute copies of the +software, or if you modify it. + +For example, if you distribute copies of such a program, whether gratis or for a +fee, you must give the recipients all the rights that you have. You must make +sure that they, too, receive or can get the source code. And you must show them +these terms so they know their rights. + +We protect your rights with two steps: (1) copyright the software, and (2) offer +you this license which gives you legal permission to copy, distribute and/or +modify the software. + +Also, for each author's protection and ours, we want to make certain that +everyone understands that there is no warranty for this free software. If the +software is modified by someone else and passed on, we want its recipients to +know that what they have is not the original, so that any problems introduced by +others will not reflect on the original authors' reputations. + +Finally, any free program is threatened constantly by software patents. We wish +to avoid the danger that redistributors of a free program will individually +obtain patent licenses, in effect making the program proprietary. To prevent +this, we have made it clear that any patent must be licensed for everyone's free +use or not licensed at all. + +The precise terms and conditions for copying, distribution and modification +follow. + +TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + +0. This License applies to any program or other work which contains a notice +placed by the copyright holder saying it may be distributed under the terms of +this General Public License. The "Program", below, refers to any such program or +work, and a "work based on the Program" means either the Program or any +derivative work under copyright law: that is to say, a work containing the +Program or a portion of it, either verbatim or with modifications and/or +translated into another language. (Hereinafter, translation is included without +limitation in the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not covered by +this License; they are outside its scope. The act of running the Program is not +restricted, and the output from the Program is covered only if its contents +constitute a work based on the Program (independent of having been made by +running the Program). Whether that is true depends on what the Program does. + +1. You may copy and distribute verbatim copies of the Program's source code as +you receive it, in any medium, provided that you conspicuously and appropriately +publish on each copy an appropriate copyright notice and disclaimer of warranty; +keep intact all the notices that refer to this License and to the absence of any +warranty; and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and you may at +your option offer warranty protection in exchange for a fee. + +2. You may modify your copy or copies of the Program or any portion of it, thus +forming a work based on the Program, and copy and distribute such modifications +or work under the terms of Section 1 above, provided that you also meet all of +these conditions: + + a) You must cause the modified files to carry prominent notices stating +that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in whole or +in part contains or is derived from the Program or any part thereof, to be +licensed as a whole at no charge to all third parties under the terms of this +License. + + c) If the modified program normally reads commands interactively when run, +you must cause it, when started running for such interactive use in the most +ordinary way, to print or display an announcement including an appropriate +copyright notice and a notice that there is no warranty (or else, saying that +you provide a warranty) and that users may redistribute the program under these +conditions, and telling the user how to view a copy of this License. (Exception: +if the Program itself is interactive but does not normally print such an +announcement, your work based on the Program is not required to print an +announcement.) + +These requirements apply to the modified work as a whole. If identifiable +sections of that work are not derived from the Program, and can be reasonably +considered independent and separate works in themselves, then this License, and +its terms, do not apply to those sections when you distribute them as separate +works. But when you distribute the same sections as part of a whole which is a +work based on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the entire whole, +and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest your +rights to work written entirely by you; rather, the intent is to exercise the +right to control the distribution of derivative or collective works based on the +Program. + +In addition, mere aggregation of another work not based on the Program with the +Program (or with a work based on the Program) on a volume of a storage or +distribution medium does not bring the other work under the scope of this +License. + +3. You may copy and distribute the Program (or a work based on it, under Section +2) in object code or executable form under the terms of Sections 1 and 2 above +provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable source +code, which must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three years, to +give any third party, for a charge no more than your cost of physically +performing source distribution, a complete machine-readable copy of the +corresponding source code, to be distributed under the terms of Sections 1 and 2 +above on a medium customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer to +distribute corresponding source code. (This alternative is allowed only for +noncommercial distribution and only if you received the program in object code +or executable form with such an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for making +modifications to it. For an executable work, complete source code means all the +source code for all modules it contains, plus any associated interface +definition files, plus the scripts used to control compilation and installation +of the executable. However, as a special exception, the source code distributed +need not include anything that is normally distributed (in either source or +binary form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component itself +accompanies the executable. + +If distribution of executable or object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the source code +from the same place counts as distribution of the source code, even though third +parties are not compelled to copy the source along with the object code. + +4. You may not copy, modify, sublicense, or distribute the Program except as +expressly provided under this License. Any attempt otherwise to copy, modify, +sublicense or distribute the Program is void, and will automatically terminate +your rights under this License. However, parties who have received copies, or +rights, from you under this License will not have their licenses terminated so +long as such parties remain in full compliance. + +5. You are not required to accept this License, since you have not signed it. +However, nothing else grants you permission to modify or distribute the Program +or its derivative works. These actions are prohibited by law if you do not +accept this License. Therefore, by modifying or distributing the Program (or any +work based on the Program), you indicate your acceptance of this License to do +so, and all its terms and conditions for copying, distributing or modifying the +Program or works based on it. + +6. Each time you redistribute the Program (or any work based on the Program), +the recipient automatically receives a license from the original licensor to +copy, distribute or modify the Program subject to these terms and conditions. +You may not impose any further restrictions on the recipients' exercise of the +rights granted herein. You are not responsible for enforcing compliance by third +parties to this License. + +7. If, as a consequence of a court judgment or allegation of patent infringement +or for any other reason (not limited to patent issues), conditions are imposed +on you (whether by court order, agreement or otherwise) that contradict the +conditions of this License, they do not excuse you from the conditions of this +License. If you cannot distribute so as to satisfy simultaneously your +obligations under this License and any other pertinent obligations, then as a +consequence you may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by all those +who receive copies directly or indirectly through you, then the only way you +could satisfy both it and this License would be to refrain entirely from +distribution of the Program. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply and the +section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any patents or +other property right claims or to contest validity of any such claims; this +section has the sole purpose of protecting the integrity of the free software +distribution system, which is implemented by public license practices. Many +people have made generous contributions to the wide range of software +distributed through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing to +distribute software through any other system and a licensee cannot impose that +choice. + +This section is intended to make thoroughly clear what is believed to be a +consequence of the rest of this License. + +8. If the distribution and/or use of the Program is restricted in certain +countries either by patents or by copyrighted interfaces, the original copyright +holder who places the Program under this License may add an explicit +geographical distribution limitation excluding those countries, so that +distribution is permitted only in or among countries not thus excluded. In such +case, this License incorporates the limitation as if written in the body of this +License. + +9. The Free Software Foundation may publish revised and/or new versions of the +General Public License from time to time. Such new versions will be similar in +spirit to the present version, but may differ in detail to address new problems +or concerns. + +Each version is given a distinguishing version number. If the Program specifies +a version number of this License which applies to it and "any later version", +you have the option of following the terms and conditions either of that version +or of any later version published by the Free Software Foundation. If the +Program does not specify a version number of this License, you may choose any +version ever published by the Free Software Foundation. + +10. If you wish to incorporate parts of the Program into other free programs +whose distribution conditions are different, write to the author to ask for +permission. For software which is copyrighted by the Free Software Foundation, +write to the Free Software Foundation; we sometimes make exceptions for this. +Our decision will be guided by the two goals of preserving the free status of +all derivatives of our free software and of promoting the sharing and reuse of +software generally. + +NO WARRANTY + +11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE +PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED +IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS +IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT +NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A +PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + +12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL +ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE +PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, +SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY +TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF +THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER +PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. + +END OF TERMS AND CONDITIONS + +How to Apply These Terms to Your New Programs + +If you develop a new program, and you want it to be of the greatest possible use +to the public, the best way to achieve this is to make it free software which +everyone can redistribute and change under these terms. + +To do so, attach the following notices to the program. It is safest to attach +them to the start of each source file to most effectively convey the exclusion +of warranty; and each file should have at least the "copyright" line and a +pointer to where the full notice is found. + + one line to give the program's name and an idea of what it does. Copyright +(C) yyyy name of author + + This program is free software; you can redistribute it and/or modify it +under the terms of the GNU General Public License as published by the Free +Software Foundation; either version 2 of the License, or (at your option) any +later version. + + This program is distributed in the hope that it will be useful, but WITHOUT +ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS +FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. + + You should have received a copy of the GNU General Public License along +with this program; if not, write to the Free Software Foundation, Inc., 51 +Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA. Also add information +on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this when it +starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author Gnomovision comes +with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, +and you are welcome to redistribute it under certain conditions; type `show c' +for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may be +called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your school, +if any, to sign a "copyright disclaimer" for the program, if necessary. Here is +a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program +`Gnomovision' (which makes passes at compilers) written by James Hacker. + +signature of Ty Coon, 1 April 1989 Ty Coon, President of Vice diff --git a/README.md b/README.md new file mode 100644 index 0000000..f2898a6 --- /dev/null +++ b/README.md @@ -0,0 +1,28 @@ +# ReactPHP Utilities + +## Installing + +```bash +$ composer set repositories.noccylabs \ + '{"type":"composer","url":"https://dev.noccylabs.info/api/packages/noccylabs/composer"}' +$ composer require noccylabs/react-utilities + +``` + +## Functions + +### NoccyLabs\React\Utilities\defer(callable $cb) + +This function is an alias for `Loop::futureTick`. + +### NoccyLabs\React\Utilities\enqueue(callable $cb) + +This function is a concurrency-friendly alternative to defer.
