Crayon Language Files

By Aram Kocharyan, http://aramk.com/

Known Elements

These are known, recognised and highlighted by Crayon. You can defined others, but if you want to highlight them, you must add your custom CSS class into a Theme file. The CSS classes are in square brackets, but have a "crayon-" prefix added to them to avoid conflicts.

  • COMMENT [c]
  • STRING [s]
  • PREPROCESSOR [p]
  • TAG [ta]
  • KEYWORD [k]
    • STATEMENT [st]
    • RESERVED [r]
    • TYPE [t]
    • MODIFIER [m]
  • IDENTIFIER [i]
    • ENTITY [e]
    • VARIABLE [v]
  • CONSTANT [cn]
  • OPERATOR [o]
  • SYMBOL [sy]
  • NOTATION [n]
  • FADED [f]
  • HTML_CHAR [h]

Rules

Global

  • Whitespace must be used to separate element names, css classes and regex
  • Must be defined on a single line

Elements

  • Defined as ELEMENT_NAME [css] REGEX on a single line, in that order only
  • Names cannot contain whitespace (must match [-_a-zA-Z]+[-_a-zA-Z0-9]*).
  • When defining an unknown element, you can specify a fallback with a colon:
    • e.g. MAGIC_WORD:KEYWORD [mg] \bmagic|words|here\b
    • If the Theme doesn't support the '.mg' class, it will still highlight using the KEYWORD class from the Known Elements section.
    • Add support for the '.mg' class by adding it at the bottom of the Theme CSS file, after the fallback
  • If duplicate exists, it replaces previous

CSS

  • CSS classes are defined in [square brackets], they are optional.
  • No need to use '.' in class name. All characters are converted to lowercase and dots removed.
  • If you use a space, then two classes are applied to the element matches e.g. [first second]
  • If not specified, either default is used (if element is known), or element name is used
  • Class can be applied to multiple elements
  • Class should be valid: [-_a-zA-Z]+[-_a-zA-Z0-9]*
  • If class is invalid, element is still parsed, error reported

Regex

  • Written as per normal, without delimiters or escaping
  • Applied in the order they appear in the file. If language has reserved keywords, these should be higher than variables
  • Whitespace around regex is ignored - only first character to last forms regex
  • If single space is intended, use \s to avoid conflict with whitespace used for separation e.g. TEST [t] \s\s\shello

Comments

  • can be added to this file using #, // or /* */
  • //, # and /* must be the first non-whitespace characters on that line
  • The */ must be on a line by itself

Special Functions

  • Written inside regex, replaced by their outputs when regex is parsed.

(?alt:file.txt)

  • Import lines from a file and separate with alternation. e.g. catdog|dog|cat
  • File should list words from longest to shortest to avoid clashes

(?default) or (?default:element_name)

  • Substitute regex with Default language's regex for that element, or a specific element given after a colon.

(?html:somechars)

  • Convert somechars to html entities. e.g. (?html:<>"'&) becomes &lt;&gt;&quot;&amp;.

Aliases

The aliases.txt contains aliases in the following structure. They are case insensitive:

Format: id alias1 alias2 ...
Example: c# cs csharp

Specifying the alias will use the original language, though it's recommended to use the original if manually specifying the language to reduce confusion and length.

Extensions

Crayon can autodetect a language when highlighting local or remote files with extensions. The extensions.txt file uses the following format:

Format: ID EXTENSION1 EXTENSION2 ...
Example: python py pyw pyc pyo pyd

Delimiters

Certain languages have tags which separate content in that language with that of another. An example is PHP's <?php ?> tags and the <script> and <style> tags in XHTML and CSS. The delimiters.txt file contains regex to capture delimiters that allow code with mixed highlighting. The format of these is:

Format: id REGEX1 REGEX2 ...
Example: php <\?(?:php)?.*?\?\>
