IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE +LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION +OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION +WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. + + + + +GPL VERSION 3 + + + + + GNU GENERAL PUBLIC LICENSE + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The GNU General Public License is a free, copyleft license for +software and other kinds of works. + + The licenses for most software and other practical works are designed +to take away your freedom to share and change the works. By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. 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 +them 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 prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. 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. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey 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; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If 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 convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU 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 that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + 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. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +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. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + diff --git a/vendor/leafo/lessphp/Makefile b/vendor/leafo/lessphp/Makefile new file mode 100644 index 00000000..a5d262cd --- /dev/null +++ b/vendor/leafo/lessphp/Makefile @@ -0,0 +1,7 @@ + +test: + phpunit --colors tests + +release: + ./package.sh + diff --git a/vendor/leafo/lessphp/README.md b/vendor/leafo/lessphp/README.md new file mode 100644 index 00000000..1379ddce --- /dev/null +++ b/vendor/leafo/lessphp/README.md @@ -0,0 +1,96 @@ +[](https://travis-ci.org/leafo/lessphp) + +# lessphp v0.5.0 +### <http://leafo.net/lessphp> + +`lessphp` is a compiler for LESS written in PHP.

All CSS +is compatible with LESS, so you can start using new features with your existing CSS. + +It is designed to be compatible with [less.js](http://lesscss.org), and suitable +as a drop in replacement for PHP projects. + +## Getting Started + +The homepage for **lessphp** can be found at [http://leafo.net/lessphp/][1]. + +You can follow development at the project's [GitHub][2]. + +Including **lessphp** in your project is as simple as dropping the single +include file into your code base and running the appropriate compile method as +described in the [PHP Interface](#php_interface). + + [1]: http://leafo.net/lessphp "lessphp homepage" + [2]: https://github.com/leafo/lessphp "lessphp GitHub page" + +## Installation + +**lessphp** is distributed entirely in a single stand-alone file. Download the +latest version from either [the homepage][1] or [GitHub][2]. + +Development versions can also be downloading from GitHub. + +Place `lessphp.inc.php` in a location available to your PHP scripts, and +include it. That's it! you're ready to begin. + +## The Language + +**lessphp** is very easy to learn because it generally functions how you would +expect it to. If you feel something is challenging or missing, feel free to +open an issue on the [bug tracker](https://github.com/leafo/lessphp/issues). + +It is also easy to learn because any standards-compliant CSS code is valid LESS +code. You are free to gradually enhance your existing CSS code base with LESS +features without having to worry about rewriting anything. + +The following is a description of the new languages features provided by LESS. + +### Line Comments + +Simple but very useful; line comments are started with `//`: + + ```less + // this is a comment + body { + color: red; // as is this + /* block comments still work also */ + } + ``` + +### Variables + +Variables are identified with a name that starts with `@`. To declare a +variable, you create an appropriately named CSS property and assign it a value: + + ```less + @family: "verdana"; + @color: red; + body { + @mycolor: red; + font-family: @family; + color: @color; + border-bottom: 1px solid @color; + } + ``` + +Variable declarations will not appear in the output. Variables can be declared +in the outer most scope of the file, or anywhere else a CSS property may +appear. They can hold any CSS property value. + +Variables are only visible for use from their current scope, or any enclosed +scopes. + +If you have a string or keyword in a variable, you can reference another +variable by that name by repeating the `@`: + + ```less + @value: 20px; + @value_name: "value"; + + width: @@value_name; + ``` + +### Expressions + +Expressions let you combine values and variables in meaningful ways. For +example you can add to a color to make it a different shade. Or divide up the +width of your layout logically. You can even concatenate strings. + +Use the mathematical operators to evaluate an expression: + + ```less + @width: 960px; + .nav { + width: @width / 3; + color: #001 + #abc; + } + .body { + width: 2 * @width / 3; + font-family: "hel" + "vetica"; + } + ``` + +Parentheses can be used to control the order of evaluation. They can also be +used to force an evaluation for cases where CSS's syntax makes the expression +ambiguous. + +The following property will produce two numbers, instead of doing the +subtraction: + + ```less + margin: 10px -5px; + ``` + +To force the subtraction: + + ```less + margin: (10px -5px); + ``` + +It is also safe to surround mathematical operators by spaces to ensure that +they are evaluated: + + ```less + margin: 10px - 5px; + ``` + +Division has a special quirk. There are certain CSS properties that use the `/` +operator as part of their value's syntax. Namely, the [font][4] shorthand and +[border-radius][3]. + + [3]: https://developer.mozilla.org/en/CSS/border-radius + [4]: https://developer.mozilla.org/en/CSS/font + + +Thus, **lessphp** will ignore any division in these properties unless it is +wrapped in parentheses. For example, no division will take place here: + + ```less + .font { + font: 20px/80px "Times New Roman"; + } + ``` + +In order to force division we must wrap the expression in parentheses: + + ```less + .font { + font: (20px/80px) "Times New Roman"; + } + ``` + +If you want to write a literal `/` expression without dividing in another +property (or a variable), you can use [string unquoting](#string_unquoting): + + ```less + .var { + @size: ~"20px/80px"; + font: @size sans-serif; + } + ``` + +### Nested Blocks + +By nesting blocks we can build up a chain of CSS selectors through scope +instead of repeating them. In addition to reducing repetition, this also helps +logically organize the structure of our CSS. + + ```less + ol.list { + li.special { + border: 1px solid red; + } + + li.plain { + font-weight: bold; + } + } + ``` + + +This will produce two blocks, a `ol.list li.special` and `ol.list li.plain`. + +Blocks can be nested as deep as required in order to build a hierarchy of +relationships. + +The `&` operator can be used in a selector to represent its parent's selector. +If the `&` operator is used, then the default action of appending the parent to +the front of the child selector separated by space is not performed. + + ```less + b { + a & { + color: red; + } + + // the following have the same effect + + & i { + color: blue; + } + + i { + color: blue; + } + } + ``` + + +Because the `&` operator respects the whitespace around it, we can use it to +control how the child blocks are joined. Consider the differences between the +following: + + ```less + div { + .child-class { color: purple; } + + &.isa-class { color: green; } + + #child-id { height: 200px; } + + &#div-id { height: 400px; } + + &:hover { color: red; } + + :link { color: blue; } + } + ``` + +The `&` operator also works with [mixins](#mixins), which produces interesting results: + + ```less + .within_box_style() { + .box & { + color: blue; + } + } + + #menu { + .within_box_style; + } + ``` + +### Mixins + +Any block can be mixed in just by naming it: + + ```less + .mymixin { + color: blue; + border: 1px solid red; + + .special { + font-weight: bold; + } + } + + + h1 { + font-size: 200px; + .mymixin; + } + ``` + +All properties and child blocks are mixed in. + +Mixins can be made parametric, meaning they can take arguments, in order to +enhance their utility. A parametric mixin all by itself is not outputted when +compiled. Its properties will only appear when mixed into another block. + +The canonical example is to create a rounded corners mixin that works across +browsers: + + ```less + .rounded-corners(@radius: 5px) { + border-radius: @radius; + -webkit-border-radius: @radius; + -moz-border-radius: @radius; + } + + .header { + .rounded-corners(); + } + + .info { + background: red; + .rounded-corners(14px); + } + ``` + +If you have a mixin that doesn't have any arguments, but you don't want it to +show up in the output, give it a blank argument list: + + ```less + .secret() { + font-size: 6000px; + } + + .div { + .secret; + } + ``` + +If the mixin doesn't need any arguments, you can leave off the parentheses when +mixing it in, as seen above. + +You can also mixin a block that is nested inside other blocks. You can think of +the outer block as a way of making a scope for your mixins. You just list the +names of the mixins separated by spaces, which describes the path to the mixin +you want to include. Optionally you can separate them by `>`. + + ```less + .my_scope { + .some_color { + color: red; + .inner_block { + text-decoration: underline; + } + } + .bold { + font-weight: bold; + color: blue; + } + } + + .a_block { + .my_scope .some_color; + .my_scope .some_color .inner_block; + } + + .another_block { + // the alternative syntax + .my_scope > .bold; + } + ``` + + +#### Mixin Arguments + +When declaring a mixin you can specify default values for each argument. Any +argument left out will be given the default value specified. Here's the +syntax: + +```less +.mix(@color: red, @height: 20px, @pad: 12px) { + border: 1px solid @color; + height: @height - @pad; + padding: @pad; +} + +.default1 { + .mix(); +} + +.default2 { + .mix(blue); +} + +.default3 { + .mix(blue, 40px, 5px); +} +``` + +Additionally, you can also call a mixin using the argument names, this is +useful if you want to replace a specific argument while having all the others +take the default regardless of what position the argument appears in. The +syntax looks something like this: + + +```lessbasic +div { + .my_mixin(@paddding: 4px); // @color and @height get default values + .my_mixin(@paddding: 4px, @height: 50px); // you can specify them in any order +} +``` + +You can also combine the ordered arguments with the named ones: + +```lessbasic +div { + // @color is blue, @padding is 4px, @height is default + .my_mixin(blue, @padding: 4px); +} +``` + +Mixin arguments can be delimited with either a `,` or `;`, but only one can be +active at once. This means that each argument is separated by either `,` or +`;`. By default `,` is the delimiter, in all the above examples we used a `,`. + +A problem arises though, sometimes CSS value lists are made up with commas. In +order to be able to pass a comma separated list literal we need to use `;` as +the delimiter. (You don't need to worry about this if your list is stored in a +variable) + +If a `;` appears anywhere in the argument list, then it will be used as the +argument delimiter, and all commas we be used as part of the argument values. + +Here's a basic example: + +```less +.fancy_mixin(@box_shadow, @color: blue) { + border: 1px solid @color; + box-shadow: @box_shadow; +} + + +div { + // two arguments passed separated by ; + .fancy_mixin(2px 2px, -2px -2px; red); +} + +pre { + // one argument passed, ends in ; + .fancy_mixin(inset 4px 4px, -2px 2px;); +} + +``` + +If we only want to pass a single comma separated value we still need to use +`;`, to do this we stick it on the end as demonstrated above. + + +#### `@arguments` Variable + +Within an mixin there is a special variable named `@arguments` that contains +all the arguments passed to the mixin along with any remaining arguments that +have default values. The value of the variable has all the values separated by +spaces. + +This useful for quickly assigning all the arguments: + + ```less + .box-shadow(@x, @y, @blur, @color) { + box-shadow: @arguments; + -webkit-box-shadow: @arguments; + -moz-box-shadow: @arguments; + } + .menu { + .box-shadow(1px, 1px, 5px, #aaa); + } + ``` + +In addition to the arguments passed to the mixin, `@arguments` will also include +remaining default values assigned by the mixin: + + + ```less + .border-mixin(@width, @style: solid, @color: black) { + border: @arguments; + } + + pre { + .border-mixin(4px, dotted); + } + + ``` + + +#### Pattern Matching + +When you *mix in* a mixin, all the available mixins of that name in the current +scope are checked to see if they match based on what was passed to the mixin +and how it was declared. + +The simplest case is matching by number of arguments. Only the mixins that +match the number of arguments passed in are used. + + ```less + .simple() { // matches no arguments + height: 10px; + } + + .simple(@a, @b) { // matches two arguments + color: red; + } + + .simple(@a) { // matches one argument + color: blue; + } + + div { + .simple(10); + } + + span { + .simple(10, 20); + } + ``` + +Whether an argument has default values is also taken into account when matching +based on number of arguments: + + ```less + // matches one or two arguments + .hello(@a, @b: blue) { + height: @a; + color: @b; + } + + .hello(@a, @b) { // matches only two + width: @a; + border-color: @b; + } + + .hello(@a) { // matches only one + padding: 1em; + } + + div { + .hello(10px); + } + + pre { + .hello(10px, yellow); + } + ``` + +Additionally, a *vararg* value can be used to further control how things are +matched. A mixin's argument list can optionally end in the special argument +named `...`. The `...` may match any number of arguments, including 0. + + ```less + // this will match any number of arguments + .first(...) { + color: blue; + } + + // matches at least 1 argument + .second(@arg, ...) { + height: 200px + @arg; + } + + div { .first("some", "args"); } + pre { .second(10px); } + ``` + +If you want to capture the values that get captured by the *vararg* you can +give it a variable name by putting it directly before the `...`. This variable +must be the last argument defined. It's value is just like the special +[`@arguments` variable](#arguments_variable), a space separated list. + + + ```less + .hello(@first, @rest...) { + color: @first; + text-shadow: @rest; + } + + span { + .hello(red, 1px, 1px, 0px, white); + } + + ``` + +Another way of controlling whether a mixin matches is by specifying a value in +place of an argument name when declaring the mixin: + + ```less + .style(old, @size) { + font: @size serif; + } + + .style(new, @size) { + font: @size sans-serif; + } + + .style(@_, @size) { + letter-spacing: floor(@size / 6px); + } + + em { + @switch: old; + .style(@switch, 15px); + } + ``` + +Notice that two of the three mixins were matched. The mixin with a matching +first argument, and the generic mixin that matches two arguments. It's common +to use `@_` as the name of a variable we intend to not use. It has no special +meaning to LESS, just to the reader of the code. + +#### Guards + +Another way of restricting when a mixin is mixed in is by using guards. A guard +is a special expression that is associated with a mixin declaration that is +evaluated during the mixin process. It must evaluate to true before the mixin +can be used. + +We use the `when` keyword to begin describing a list of guard expressions. + +Here's a simple example: + + ```less + .guarded(@arg) when (@arg = hello) { + color: blue; + } + + div { + .guarded(hello); // match + } + + span { + .guarded(world); // no match + } + ``` +Only the `div`'s mixin will match in this case, because the guard expression +requires that `@arg` is equal to `hello`. + +We can include many different guard expressions by separating them by commas. +Only one of them needs to match to trigger the mixin: + + ```less + .x(@a, @b) when (@a = hello), (@b = world) { + width: 960px; + } + + div { + .x(hello, bar); // match + } + + span { + .x(foo, world); // match + } + + pre { + .x(foo, bar); // no match + } + ``` + +Instead of a comma, we can use `and` keyword to make it so all of the guards +must match in order to trigger the mixin. `and` has higher precedence than the +comma. + + ```less + .y(@a, @b) when (@a = hello) and (@b = world) { + height: 600px; + } + + div { + .y(hello, world); // match + } + + span { + .y(hello, bar); // no match + } + ``` + +Commas and `and`s can be mixed and matched. + +You can also negate a guard expression by using `not` in from of the parentheses: + + ```less + .x(@a) when not (@a = hello) { + color: blue; + } + + div { + .x(hello); // no match + } + ``` + +The `=` operator is used to check equality between any two values. For numbers +the following comparison operators are also defined: + +`<`, `>`, `=<`, `>=` + +There is also a collection of predicate functions that can be used to test the +type of a value. + +These are `isnumber`, `iscolor`, `iskeyword`, `isstring`, `ispixel`, +`ispercentage` and `isem`. + + ```less + .mix(@a) when (ispercentage(@a)) { + height: 500px * @a; + } + .mix(@a) when (ispixel(@a)) { + height: @a; + } + + div.a { + .mix(50%); + } + + div.a { + .mix(350px); + } + ``` + +#### !important + +If you want to apply the `!important` suffix to every property when mixing in a +mixin, just append `!important` to the end of the call to the mixin: + + ```less + .make_bright { + color: red; + font-weight: bold; + } + + .color { + color: green; + } + + body { + .make_bright() !important; + .color(); + } + + ``` + +### Selector Expressions + +Sometimes we want to dynamically generate the selector of a block based on some +variable or expression. We can do this by using *selector expressions*. Selector +expressions are CSS selectors that are evaluated in the current scope before +being written out. + +A simple example is a mixin that dynamically creates a selector named after the +mixin's argument: + + ```less + .create-selector(@name) { + @{name} { + color: red; + } + } + + .create-selector(hello); + .create-selector(world); + ``` + +The string interpolation syntax works inside of selectors, letting you insert varaibles. + +Here's an interesting example adapted from Twitter Bootstrap. A couple advanced +things are going on. We are using [Guards](#guards) along with a recursive +mixin to work like a loop to generate a series of CSS blocks. + + + ```less + // create our recursive mixin: + .spanX (@index) when (@index > 0) { + .span@{index} { + width: @index * 100px; + } + .spanX(@index - 1); + } + .spanX (0) {} + + // mix it into the global scopee: + .spanX(4); + ``` + +### Import + +Multiple LESS files can be compiled into a single CSS file by using the +`@import` statement. Be careful, the LESS import statement shares syntax with +the CSS import statement. If the file being imported ends in a `.less` +extension, or no extension, then it is treated as a LESS import. Otherwise it +is left alone and outputted directly: + + ```lessbasic + // my_file.less + .some-mixin(@height) { + height: @height; + } + + // main.less + @import "main.less" // will import the file if it can be found + @import "main.css" // will be left alone + + body { + .some-mixin(400px); + } + ``` + +All of the following lines are valid ways to import the same file: + + ```lessbasic + @import "file"; + @import 'file.less'; + @import url("file"); + @import url('file'); + @import url(file); + ``` + +When importing, the `importDir` is searched for files. This can be configured, +see [PHP Interface](#php_interface). + +A file is only imported once. If you try to include the same file multiple +times all the import statements after the first produce no output. + +### String Interpolation + +String interpolation is a convenient way to insert the value of a variable +right into a string literal. Given some variable named `@var_name`, you just +need to write it as `@{var_name}` from within the string to have its value +inserted: + + ```less + @symbol: ">"; + h1:before { + content: "@{symbol}: "; + } + + h2:before { + content: "@{symbol}@{symbol}: "; + } + ``` + +There are two kinds of strings, implicit and explicit strings. Explicit strings +are wrapped by double quotes, `"hello I am a string"`, or single quotes `'I am +another string'`. Implicit strings only appear when using `url()`. The text +between the parentheses is considered a string and thus string interpolation is +possible: + + ```less + @path: "files/"; + body { + background: url(@{path}my_background.png); + } + ``` + +### String Format Function + +The `%` function can be used to insert values into strings using a *format +string*. It works similar to `printf` seen in other languages. It has the +same purpose as string interpolation above, but gives explicit control over +the output format. + + ```less + @symbol: ">"; + h1:before { + content: %("%s: ", @symbol); + } + ``` + +The `%` function takes as its first argument the format string, following any +number of addition arguments that are inserted in place of the format +directives. + +A format directive starts with a `%` and is followed by a single character that +is either `a`, `d`, or `s`: + + ```less + strings: %("%a %d %s %a", hi, 1, 'ok', 'cool'); + ``` + +`%a` and `%d` format the value the same way: they compile the argument to its +CSS value and insert it directly. When used with a string, the quotes are +included in the output. This typically isn't what we want, so we have the `%s` +format directive which strips quotes from strings before inserting them. + +The `%d` directive functions the same as `%a`, but is typically used for numbers +assuming the output format of numbers might change in the future. + +### String Unquoting + +Sometimes you will need to write proprietary CSS syntax that is unable to be +parsed. As a workaround you can place the code into a string and unquote it. +Unquoting is the process of outputting a string without its surrounding quotes. +There are two ways to unquote a string. + +The `~` operator in front of a string will unquote that string: + + ```less + .class { + // a made up, but problematic vendor specific CSS + filter: ~"Microsoft.AlphaImage(src='image.png')"; + } + ``` + +If you are working with other types, such as variables, there is a built in +function that let's you unquote any value. It is called `e`. + + ```less + @color: "red"; + .class { + color: e(@color); + } + ``` + +### Built In Functions + +**lessphp** has a collection of built in functions: + +* `e(str)` -- returns a string without the surrounding quotes. + See [String Unquoting](#string_unquoting) + +* `floor(number)` -- returns the floor of a numerical input +* `round(number, [precision])` -- returns the rounded value of numerical input with optional precision + +* `lighten(color, percent)` -- lightens `color` by `percent` and returns it +* `darken(color, percent)` -- darkens `color` by `percent` and returns it + +* `saturate(color, percent)` -- saturates `color` by `percent` and returns it +* `desaturate(color, percent)` -- desaturates `color` by `percent` and returns it + +* `fadein(color, percent)` -- makes `color` less transparent by `percent` and returns it +* `fadeout(color, percent)` -- makes `color` more transparent by `percent` and returns it + +* `spin(color, amount)` -- returns a color with `amount` degrees added to hue + +* `fade(color, amount)` -- returns a color with the alpha set to `amount` + +* `hue(color)` -- returns the hue of `color` + +* `saturation(color)` -- returns the saturation of `color` + +* `lightness(color)` -- returns the lightness of `color` + +* `alpha(color)` -- returns the alpha value of `color` or 1.0 if it doesn't have an alpha + +* `percentage(number)` -- converts a floating point number to a percentage, e.g. `0.65` -> `65%` + +* `mix(color1, color1, percent)` -- mixes two colors by percentage where 100% + keeps all of `color1`, and 0% keeps all of `color2`.

It will either return the +result or write it to the path specified by an optional second argument. + + ```php + echo $less->compileFile("input.less"); + ``` + +The `compileChecked` method is like `compileFile`, but it only compiles if the output +file doesn't exist or it's older than the input file: + + ```php + $less->checkedCompile("input.less", "output.css"); + ``` + +See [Compiling Automatically](#compiling_automatically) for a description of +the more advanced `cachedCompile` method. + +### Output Formatting + +Output formatting controls the indentation of the output CSS. Besides the +default formatter, two additional ones are included and it's also easy to make +your own. + +To use a formatter, the method `setFormatter` is used. Just +pass the name of the formatter: + + ```php + $less = new lessc; + + $less->setFormatter("compressed"); + echo $less->compile("div { color: lighten(blue, 10%) }"); + ``` + +In this example, the `compressed` formatter is used. The formatters are: + + * `lessjs` *(default)* -- Same style used in LESS for JavaScript + + * `compressed` -- Compresses all the unrequired whitespace + + * `classic` -- **lessphp**'s original formatter + +To revert to the default formatter, call `setFormatter` with a value of `null`. + +#### Custom Formatter + +The easiest way to customize the formatter is to create your own instance of an +existing formatter and alter its public properties before passing it off to +**lessphp**. The `setFormatter` method can also take an instance of a +formatter. + +Each of the formatter names corresponds to a class with `lessc_formatter_` +prepended in front of it. Here the classic formatter is customized to use tabs +instead of spaces: + + + ```php + $formatter = new lessc_formatter_classic; + $formatter->indentChar = "\t"; + + $less = new lessc; + $less->setFormatter($formatter); + echo $less->compileFile("myfile.less"); + ``` + +For more information about what can be configured with the formatter consult +the source code. + +### Preserving Comments + +By default, all comments in the source LESS file are stripped when compiling. +You might want to keep the `/* */` comments in the output though. For +example, bundling a license in the file. + +Enable or disable comment preservation by calling `setPreserveComments`: + + ```php + $less = new lessc; + $less->setPreserveComments(true); + echo $less->compile("/* hello! */"); + ``` + +Comments are disabled by default because there is additional overhead, and more +often than not they aren't needed. + + +### Compiling Automatically + +Often, you want to only compile a LESS file only if it has been modified since +last compile. This is very important because compiling is performance intensive +and you should avoid a recompile if it possible. + +The `checkedCompile` compile method will do just that. It will check if the +input file is newer than the output file, or if the output file doesn't exist +yet, and compile only then. + + ```php + $less->checkedCompile("input.less", "output.css"); + ``` + +There's a problem though. `checkedCompile` is very basic, it only checks the +input file's modification time. It is unaware of any files from `@import`. + + +For this reason we also have `cachedCompile`. It's slightly more complex, but +gives us the ability to check changes to all files including those imported. It +takes one argument, either the name of the file we want to compile, or an +existing *cache object*. Its return value is an updated cache object. + +If we don't have a cache object, then we call the function with the name of the +file to get the initial cache object. If we do have a cache object, then we +call the function with it. In both cases, an updated cache object is returned. + +The cache object keeps track of all the files that must be checked in order to +determine if a rebuild is required. + +The cache object is a plain PHP `array`. It stores the last time it compiled in +`$cache["updated"]` and output of the compile in `$cache["compiled"]`. + +Here we demonstrate creating an new cache object, then using it to see if we +have a recompiled version available to be written: + + + ```php + $inputFile = "myfile.less"; + $outputFile = "myfile.css"; + + $less = new lessc; + + // create a new cache object, and compile + $cache = $less->cachedCompile($inputFile); + + file_put_contents($outputFile, $cache["compiled"]); + + // the next time we run, write only if it has updated + $last_updated = $cache["updated"]; + $cache = $less->cachedCompile($cache); + if ($cache["updated"] > $last_updated) { + file_put_contents($outputFile, $cache["compiled"]); + } + + ``` + +In order for the system to fully work, we must save cache object between +requests. Because it's a plain PHP `array`, it's sufficient to +[`serialize`](http://php.net/serialize) it and save it the string somewhere +like a file or in persistent memory. + +An example with saving cache object to a file: + + ```php + function autoCompileLess($inputFile, $outputFile) { + // load the cache + $cacheFile = $inputFile.".cache"; + + if (file_exists($cacheFile)) { + $cache = unserialize(file_get_contents($cacheFile)); + } else { + $cache = $inputFile; + } + + $less = new lessc; + $newCache = $less->cachedCompile($cache); + + if (!is_array($cache) || $newCache["updated"] > $cache["updated"]) { + file_put_contents($cacheFile, serialize($newCache)); + file_put_contents($outputFile, $newCache['compiled']); + } + } + + autoCompileLess('myfile.less', 'myfile.css'); + ``` + +`cachedCompile` method takes an optional second argument, `$force`. Passing in +true will cause the input to always be recompiled. + +### Error Handling + +All of the compile methods will throw an `Exception` if the parsing fails or +there is a compile time error. Compile time errors include things like passing +incorrectly typed values for functions that expect specific things, like the +color manipulation functions. + + ```php + $less = new lessc; + try { + $less->compile("} invalid LESS }}}"); + } catch (Exception $ex) { + echo "lessphp fatal error: ".$ex->getMessage(); + } + ``` +### Setting Variables From PHP + +Before compiling any code you can set initial LESS variables from PHP. The +`setVariables` method lets us do this. It takes an associative array of names +to values. The values must be strings, and will be parsed into correct CSS +values. + + + ```php + $less = new lessc; + + $less->setVariables(array( + "color" => "red", + "base" => "960px" + )); + + echo $less->compile(".magic { color: @color; width: @base - 200; }"); + ``` + +If you need to unset a variable, the `unsetVariable` method is available. It +takes the name of the variable to unset. + + ```php + $less->unsetVariable("color"); + ``` + +Be aware that the value of the variable is a string containing a CSS value. So +if you want to pass a LESS string in, you're going to need two sets of quotes. +One for PHP and one for LESS. + + + ```php + $less->setVariables(array( + "url" => "'http://example.com.com/'" + )); + + echo $less->compile("body { background: url("@{url}/bg.png"); }"); + ``` + +### Import Directory + +When running the `@import` directive, an array of directories called the import +search path is searched through to find the file being asked for. + +By default, when using `compile`, the import search path just contains `""`, +which is equivalent to the current directory of the script. If `compileFile` is +used, then the directory of the file being compiled is used as the starting +import search path. + +Two methods are available for configuring the search path. + +`setImportDir` will overwrite the search path with its argument. If the value +isn't an array it will be converted to one. + + +In this example, `@import "colors";` will look for either +`assets/less/colors.less` or `assets/bootstrap/colors.less` in that order: + + ```php + $less->setImportDir(array("assets/less/", "assets/bootstrap")); + + echo $less->compile('@import "colors";'); + ``` + +`addImportDir` will append a single path to the import search path instead of +overwriting the whole thing. + + ```php + $less->addImportDir("public/stylesheets"); + ``` + +### Custom Functions + +**lessphp** has a simple extension interface where you can implement user +functions that will be exposed in LESS code during the compile. They can be a +little tricky though because you need to work with the **lessphp** type system. + +The two methods we are interested in are `registerFunction` and +`unregisterFunction`. `registerFunction` takes two arguments, a name and a +callable value. `unregisterFunction` just takes the name of an existing +function to remove. + +Here's an example that adds a function called `double` that doubles any numeric +argument: + + ```php + <?php + include "lessc.inc.php"; + + function lessphp_double($arg) { + list($type, $value) = $arg; + return array($type, $value*2); + } + + $less = new lessc; + $less->registerFunction("double", "lessphp_double"); + + // gives us a width of 800px + echo $less->compile("div { width: double(400px); }"); + ``` + +The second argument to `registerFunction` is any *callable value* that is +understood by [`call_user_func`](http://php.net/call_user_func). + +If we are using PHP 5.3 or above then we are free to pass a function literal +like so: + + ```php + $less->registerFunction("double", function($arg) { + list($type, $value, $unit) = $arg; + return array($type, $value*2, $unit); + }); + ``` + +Now let's talk about the `double` function itself. + +Although a little verbose, the implementation gives us some insight on the type +system. All values in **lessphp** are stored in an array where the 0th element +is a string representing the type, and the other elements make up the +associated data for that value. + +The best way to get an understanding of the system is to register is dummy +function which does a `var_dump` on the argument. Try passing the function +different values from LESS and see what the results are. + +The return value of the registered function must also be a **lessphp** type, +but if it is a string or numeric value, it will automatically be coerced into +an appropriate typed value. In our example, we reconstruct the value with our +modifications while making sure that we preserve the original type. + +The instance of **lessphp** itself is sent to the registered function as the +second argument in addition to the arguments array. + +## Command Line Interface + +**lessphp** comes with a command line script written in PHP that can be used to +invoke the compiler from the terminal. On Linux and OSX, all you need to do is +place `plessc` and `lessc.inc.php` somewhere in your PATH (or you can run it in +the current directory as well). On windows you'll need a copy of `php.exe` to +run the file. To compile a file, `input.less` to CSS, run: + + ```bash + $ plessc input.less + ``` + +To write to a file, redirect standard out: + + ```bash + $ plessc input.less > output.css + ``` + +To compile code directly on the command line: + + ```bash + $ plessc -r "@color: red; body { color: @color; }" + ``` + +To watch a file for changes, and compile it as needed, use the `-w` flag: + + ```bash + $ plessc -w input-file output-file + ``` + +Errors from watch mode are written to standard out. + + +## License + +Copyright (c) 2012 Leaf Corcoran, <http://leafo.net/lessphp> + +Permission is hereby granted, free of charge, to any person obtaining +a copy of this software and associated documentation files (the +"Software"), to deal in the Software without restriction, including +without limitation the rights to use, copy, modify, merge, publish, +distribute, sublicense, and/or sell copies of the Software, and to +permit persons to whom the Software is furnished to do so, subject to +the following conditions: + +The above copyright notice and this permission notice shall be +included in all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, +EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF +MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND +NONINFRINGEMENT.
