-GPL VERSION 3
-
-
-
-
- GNU GENERAL PUBLIC LICENSE
- Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc.
- 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,

-# lesserphp v0.5.4
-###
-
-`lesserphp` is a compiler for LESS written in PHP. It is based on lessphp bei leafo.
-The documentation is great,
-so check it out: .
-
-Here's a quick tutorial:
-
-### How to use in your PHP project
-
-The only file required is `lessc.inc.php`, so copy that to your include directory.
-
-The typical flow of **lesserphp** is to create a new instance of `lessc`,
-configure it how you like, then tell it to compile something using one built in
-compile methods.
-
-The `compile` method compiles a string of LESS code to CSS.
-
-```php
-compile(".block { padding: 3 + 4px }");
-```
-
-The `compileFile` method reads and compiles a file. It will either return the
-result or write it to the path specified by an optional second argument.
-
-```php
-compileFile("input.less");
-```
-
-The `checkedCompile` method is like `compileFile`, but it only compiles if the output
-file doesn't exist or it's older than the input file:
-
-```php
-checkedCompile("input.less", "output.css");
-```
-
-If there any problem compiling your code, an exception is thrown with a helpful message:
-
-```php
-compile("invalid LESS } {");
-} catch (\Exception $e) {
- echo "fatal error: " . $e->getMessage();
-}
-```
-
-The `lessc` object can be configured through an assortment of instance methods.
-Some possible configuration options include [changing the output format][1],
-[setting variables from PHP][2], and [controlling the preservation of
-comments][3], writing [custom functions][4] and much more. It's all described
-in [the documentation][0].

- [3]: http://leafo.net/lessphp/docs/#preserving_comments
- [4]: http://leafo.net/lessphp/docs/#custom_functions
-
-
-### How to use from the command line
-
-An additional script has been included to use the compiler from the command
-line. In the simplest invocation, you specify an input file and the compiled
-css is written to standard out:
-
- $ plessc input.less > output.css
-
-Using the -r flag, you can specify LESS code directly as an argument or, if
-the argument is left off, from standard in:
-
- $ plessc -r "my less code here"
-
-Finally, by using the -w flag you can watch a specified input file and have it
-compile as needed to the output file:
-
- $ plessc -w input-file output-file
-
-Errors from watch mode are written to standard out.
-
-The -f flag sets the [output formatter][1]. For example, to compress the
-output run this:
-
- $ plessc -f=compressed myfile.less
-
-For more help, run `plessc --help`

-$index
-
-**lesserphp** is a compiler that generates CSS from a superset language which
-adds a collection of convenient features often seen in other languages. 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 **lesserphp** can be found at [http://leafo.net/lessphp/][1].
-
-You can follow development at the project's [GitHub][2].
-
-Including **lesserphp** 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/MarcusSchwarz/lesserphp "lesserphp GitHub page"
-
-## Installation
-
-**lesserphp** is distributed entirely in a single stand-alone file. Download the
-latest version from [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
-
-**lesserphp** 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/MarcusSchwarz/lesserphp/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
-
-**lesserphp** 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`. Will take into account
- the alpha of the colors if it exists. See
- .
-
-* `contrast(color, dark, light)` -- if `color` has a lightness value greater
- than 50% then `dark` is returned, otherwise return `light`.
-
-* `extract(list, index)` -- returns the `index`th item from `list`. The list is
- `1` indexed, meaning the first item's index is 1, the second is 2, and etc.
-
-* `pow(base, exp)` -- returns `base` raised to the power of `exp`
-
-* `pi()` -- returns pi
-
-* `mod(a,b)` -- returns `a` modulus `b`
-
-* `tan(a)` -- returns tangent of `a` where `a` is in radians
-
-* `cos(a)` -- returns cosine of `a` where `a` is in radians
-
-* `sin(a)` -- returns sine of `a` where `a` is in radians
-
-* `atan(a)` -- returns arc tangent of `a`
-
-* `acos(a)` -- returns arc cosine of `a`
-
-* `asin(a)` -- returns arc sine of `a`
-
-* `sqrt(a)` -- returns square root of `a`
-
-* `rgbahex(color)` -- returns a string containing 4 part hex color.
-
- This is used to convert a CSS color into the hex format that IE's filter
- method expects when working with an alpha component.
-
- ```less
- .class {
- @start: rgbahex(rgba(25, 34, 23, .5));
- @end: rgbahex(rgba(85, 74, 103, .6));
- // abridged example
- -ms-filter:
- e("gradient(start=@{start},end=@{end})");
- }
- ```
-
-## PHP Interface
-
-When working with **lesserphp** from PHP, the typical flow is to create a new
-instance of `lessc`, configure it how you like, then tell it to compile
-something using one built in compile methods.
-
-Methods:
-
-* [`compile($string)`](#compiling[) -- Compile a string
-
-* [`compileFile($inFile, [$outFile])`](#compiling) -- Compile a file to another or return it
-
-* [`checkedCompile($inFile, $outFile)`](#compiling) -- Compile a file only if it's newer
-
-* [`cachedCompile($cacheOrFile, [$force])`](#compiling_automatically) -- Conditionally compile while tracking imports
-
-* [`setFormatter($formatterName)`](#output_formatting) -- Change how CSS output looks
-
-* [`setPreserveComments($keepComments)`](#preserving_comments) -- Change if comments are kept in output
-
-* [`registerFunction($name, $callable)`](#custom_functions) -- Add a custom function
-
-* [`unregisterFunction($name)`](#custom_functions) -- Remove a registered function
-
-* [`setVariables($vars)`](#setting_variables_from_php) -- Set a variable from PHP
-
-* [`unsetVariable($name)`](#setting_variables_from_php) -- Remove a PHP variable
-
-* [`setImportDir($dirs)`](#import_directory) -- Set the search path for imports
-
-* [`addImportDir($dir)`](#import_directory) -- Append directory to search path for imports
-
-
-### Compiling
-
-The `compile` method compiles a string of LESS code to CSS.
-
- ```php
- compile(".block { padding: 3 + 4px }");
- ```
-
-The `compileFile` method reads and compiles a file. 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 `checkedCompile` 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'"
- ));
-
- 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
-
-**lesserphp** 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 **lesserphp** 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
- 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 **lesserphp** 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 **lesserphp** 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 **lesserphp** itself is sent to the registered function as the
-second argument in addition to the arguments array.
-
-## Command Line Interface
-
-**lesserphp** 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.

-/**
- * The LESS compiler and parser.
- *
- * Converting LESS to CSS is a three stage process. The incoming file is parsed
- * by `lessc_parser` into a syntax tree, then it is compiled into another tree
- * representing the CSS structure by `lessc`. The CSS tree is fed into a
- * formatter, like `lessc_formatter` which then outputs CSS as a string.
- *
- * During the first compile, all values are *reduced*, which means that their
- * types are brought to the lowest form before being dump as strings. This
- * handles math equations, variable dereferences, and the like.
- *
- * The `parse` function of `lessc` is the entry point.
- *
- * In summary:
- *
- * The `lessc` class creates an instance of the parser, feeds it LESS code,
- * then transforms the resulting tree to a CSS tree. This class also holds the
- * evaluation context, such as all available mixins and variables at any given
- * time.
- *
- * The `lessc_parser` class is only concerned with parsing its input.
- *
- * The `lessc_formatter` takes a CSS tree, and dumps it to a formatted string,
- * handling things like indentation.

- * Recursively compiles a block.

- * A block is analogous to a CSS block in most cases. A single LESS document
- * is encapsulated in a block when parsed, but it does not have parent tags
- * so all of it's children appear on the root level when compiled.
- *
- * Blocks are made up of props and children.
- *
- * Props are property instructions, array tuples which describe an action
- * to be taken, eg. write a property, set a variable, mixin a block.
- *
- * The children of a block are just all the blocks that are defined within.
- * This is used to look up mixins when performing a mixin.
- *
- * Compiling the block involves pushing a fresh environment on the stack,
- * and iterating through the props, compiling each one.
- *
- * See lessc::compileProp()

- * Parse a single chunk off the head of the buffer and append it to the

- * Returns false when the buffer is empty, or when there is an error.
- *
- * This function is called repeatedly until the entire document is
- * parsed.
- *
- * This parser is most similar to a recursive descent parser. Single
- * functions represent discrete grammatical rules for the language, and
- * they are able to capture the text that represents those rules.
- *
- * Consider the function lessc::keyword(). (all parse functions are
- * structured the same)
- *
- * The function takes a single reference argument. When calling the
- * function it will attempt to match a keyword on the head of the buffer.
- * If it is successful, it will place the keyword in the referenced
- * argument, advance the position in the buffer, and return true. If it
- * fails then it won't advance the buffer and it will return false.
- *
- * All of these parse functions are powered by lessc::match(), which behaves
- * the same way, but takes a literal regular expression. Sometimes it is
- * more convenient to use match instead of creating a new function.
- *
- * Because of the format of the functions, to parse an entire string of
- * grammatical rules, you can chain them together using &&.
- *
- * But, if some of the rules in the chain succeed before one fails, then
- * the buffer position will be left at an invalid state. In order to
- * avoid this, lessc::seek() is used to remember and set buffer positions.
- *
- * Before parsing a chain, use $s = $this->seek() to remember the current
- * position into $s. Then if a chain fails, use $this->seek($s) to
- * go back where we started.
