-/**
- * Definition for tables.  The general idea is to extract out all of the
- * essential bits, and then reconstruct it later.
- *
- * This is a bit confusing, because the DTDs and the W3C
- * validators seem to disagree on the appropriate definition. The
- * DTD claims:
- *
- *      (CAPTION?, (COL*|COLGROUP*), THEAD?, TFOOT?, TBODY+)
- *
- * But actually, the HTML4 spec then has this to say:
- *
- *      The TBODY start tag is always required except when the table
- *      contains only one table body and no table head or foot sections.
- *      The TBODY end tag may always be safely omitted.
- *
- * So the DTD is kind of wrong.  The validator is, unfortunately, kind
- * of on crack.
- *
- * The definition changed again in XHTML1.1; and in my opinion, this
- * formulation makes the most sense.
- *
- *      caption?, ( col* | colgroup* ), (( thead?, tfoot?, tbody+ ) | ( tr+ ))
- *
- * Essentially, we have two modes: thead/tfoot/tbody mode, and tr mode.
- * If we encounter a thead, tfoot or tbody, we are placed in the former
- * mode, and we *must* wrap any stray tr segments with a tbody. But if
- * we don't run into any of them, just have tr tags is OK.

-/**
- * Takes a well formed list of tokens and fixes their nesting.
- *
- * HTML elements dictate which elements are allowed to be their children,
- * for example, you can't have a p tag in a span tag.  Other elements have
- * much more rigorous definitions: tables, for instance, require a specific
- * order for their elements.  There are also constraints not expressible by
- * document type definitions, such as the chameleon nature of ins/del
- * tags and global child exclusions.
- *
- * The first major objective of this strategy is to iterate through all the
- * nodes (not tokens) of the list of tokens and determine whether or not
- * their children conform to the element's definition.  If they do not, the
- * child definition may optionally supply an amended list of elements that
- * is valid or require that the entire node be deleted (and the previous
- * node rescanned).
- *
- * The second objective is to ensure that explicitly excluded elements of
- * an element do not appear in its children.  Code that accomplishes this
- * task is pervasive through the strategy, though the two are distinct tasks
- * and could, theoretically, be seperated (although it's not recommended).
- *
- * @note Whether or not unrecognized children are silently dropped or
- *       translated into text depends on the child definitions.
- *
- * @todo Enable nodes to be bubbled out of the structure.
- *
- * @warning This algorithm (though it may be hard to see) proceeds from
- *          a top-down fashion.  Thus, parents are processed before
- *          children.  This is easy to implement and has a nice effiency
- *          benefit, in that if a node is removed, we never waste any
- *          time processing it, but it also means that if a child
- *          changes in a non-encapsulated way (e.g. it is removed), we
- *          need to go back and reprocess the parent to see if those
- *          changes resulted in problems for the parent.  See
- *          [BACKTRACK] for an example of this.  In the current
- *          implementation, this backtracking can only be triggered when
- *          a node is removed and if that node was the sole node, the
- *          parent would need to be removed.  As such, it is easy to see
- *          that backtracking only incurs constant overhead.  If more
- *          sophisticated backtracking is implemented, care must be
- *          taken to avoid nontermination or exponential blowup.

+# %Core.EscapeInvalidChildren is no longer supported, and no longer does

+! New directive %Core.AllowHostnameUnderscore which allows underscores
+  in hostnames.
+- Eliminate quadratic behavior in DOMLex by using a proper queue.
+  Thanks Ole Laursen for noticing this.
+- Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
+  behavior in the rest of the purificaiton pipeline.  Thanks Chedburn
+  Networks for sponsoring this work.
+- Made Linkify URL parser a bit less permissive, so that non-breaking
+  spaces and commas are not included as part of URL.  Thanks nAS for fixing.
+- Fix some bad interactions with %HTML.Allowed and injectors.  Thanks
+  David Hirtz for reporting.
+- Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)

+ * This is a bit confusing, because the DTDs and the W3C

+ *
+ *      (CAPTION?, (COL*|COLGROUP*), THEAD?, TFOOT?, TBODY+)
+ *
+ * But actually, the HTML4 spec then has this to say:
+ *
+ *      The TBODY start tag is always required except when the table
+ *      contains only one table body and no table head or foot sections.
+ *      The TBODY end tag may always be safely omitted.
+ *
+ * So the DTD is kind of wrong.  The validator is, unfortunately, kind
+ * of on crack.
+ *
+ * The definition changed again in XHTML1.1; and in my opinion, this
+ * formulation makes the most sense.
+ *
+ *      caption?, ( col* | colgroup* ), (( thead?, tfoot?, tbody+ ) | ( tr+ ))

+Core.AllowHostnameUnderscore
+TYPE: bool
+VERSION: 4.6.0
+DEFAULT: false
+--DESCRIPTION--
+<p>
+    By RFC 1123, underscores are not permitted in host names.
+    (This is in contrast to the specification for DNS, RFC
+    2181, which allows underscores.)
+    However, most browsers do the right thing when faced with
+    an underscore in the host name, and so some poorly written
+    websites are written with the expectation this should work.
+    Setting this parameter to true relaxes our allowed character
+    check so that underscores are permitted.

+ * A simple array-backed queue, based off of the classic Okasaki
+ * persistent amortized queue.  The basic idea is to maintain two
+ * stacks: an input stack and an output stack.  When the output
+ * stack runs out, reverse the input stack and use it as the output
+ * stack.
+ *
+ * We don't use the SPL implementation because it's only supported
+ * on PHP 5.3 and later.
+ *
+ * Exercise: Prove that push/pop on this queue take amortized O(1) time.
+ *
+ * Exercise: Extend this queue to be a deque, while preserving amortized
+ * O(1) time.  Some care must be taken on rebalancing to avoid quadratic
+ * behaviour caused by repeatedly shuffling data from the input stack
+ * to the output stack and back.

+/**
+ * Takes a well formed list of tokens and fixes their nesting.
+ *
+ * HTML elements dictate which elements are allowed to be their children,
+ * for example, you can't have a p tag in a span tag.  Other elements have
+ * much more rigorous definitions: tables, for instance, require a specific
+ * order for their elements.  There are also constraints not expressible by
+ * document type definitions, such as the chameleon nature of ins/del
+ * tags and global child exclusions.
+ *
+ * The first major objective of this strategy is to iterate through all
+ * the nodes and determine whether or not their children conform to the
+ * element's definition.  If they do not, the child definition may
+ * optionally supply an amended list of elements that is valid or
+ * require that the entire node be deleted (and the previous node
+ * rescanned).
+ *
+ * The second objective is to ensure that explicitly excluded elements of
+ * an element do not appear in its children.  Code that accomplishes this
+ * task is pervasive through the strategy, though the two are distinct tasks
+ * and could, theoretically, be seperated (although it's not recommended).
+ *
+ * @note Whether or not unrecognized children are silently dropped or
+ *       translated into text depends on the child definitions.
+ *
+ * @todo Enable nodes to be bubbled out of the structure.  This is

-# lessphp v0.3.9
-### <http://leafo.net/lessphp>
-
-[![Build Status](https://secure.travis-ci.org/leafo/lessphp.png)](http://travis-ci.org/leafo/lessphp)
-
-`lessphp` is a compiler for LESS written in PHP. The documentation is great,
-so check it out: <http://leafo.net/lessphp/docs/>.
-
-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 **lessphp** 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
-<?php
-require "lessc.inc.php";
-
-$less = new lessc;
-echo $less->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
-<?php
-echo $less->compileFile("input.less");
-```
-
-The `compileChecked` method is like `compileFile`, but it only compiles if the output
-file doesn't exist or it's older than the input file:
-
-```php
-<?php
-$less->checkedCompile("input.less", "output.css");
-```
-
-If there any problem compiling your code, an exception is thrown with a helpful message:
-
-```php
-<?php
-try {
-  $less->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].
-
-
- [0]: http://leafo.net/lessphp/docs/
- [1]: http://leafo.net/lessphp/docs/#output_formatting
- [2]: http://leafo.net/lessphp/docs/#setting_variables_from_php
- [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`

-
-**lessphp** 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 **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;
-      .mixin;
-    }
-    ```
-
-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;
-    }
-    ```
-
-#### `@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) {
-      (e(@name)) {
-        color: red;
-      }
-    }
-
-    .create-selector("hello");
-    .create-selector("world");
-    ```
-
-Any selector that is enclosed in `()` will have it's contents evaluated and
-directly written to output. The value is not changed any way before being
-outputted, thats why we use the `e` function. If you're not familiar, the `e`
-function strips quotes off a string value. If we didn't have it, then the
-selector would have quotes around it, and that's not valid CSS!
-
-Any value can be used in a selector expression, but it works best when using
-strings and things like [String Interpolation](#string_interpolation).
-
-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:
-
-    ```less
-    // 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:
-
-    ```less
-    @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).
-
-### 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)` -- returns the rounded value of numerical input
-
-* `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
-  <http://sass-lang.com/docs/yardoc/Sass/Script/Functions.html#mix-instance_method>.
-
-* `constrast(color, dark, light)` -- if `color` has a lightness value greater
-  than 50% then `dark` is returned, otherwise return `light`.
-
-* `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 **lessphp** 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
-    <?php
-    require "lessc.inc.php";
-
-    $less = new lessc;
-    echo $less->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 `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
-overwritting 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 an 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.
