- /** Given triples of [style, pattern, context] returns a lexing function,
- * The lexing function interprets the patterns to find token boundaries and
- * returns a decoration list of the form
- * [index_0, style_0, index_1, style_1, ..., index_n, style_n]
- * where index_n is an index into the sourceCode, and style_n is a style
- * constant like PR_PLAIN. index_n-1 <= index_n, and style_n-1 applies to
- * all characters in sourceCode[index_n-1:index_n].
- *
- * The stylePatterns is a list whose elements have the form
- * [style : string, pattern : RegExp, DEPRECATED, shortcut : string].
- *
- * Style is a style constant like PR_PLAIN, or can be a string of the
- * form 'lang-FOO', where FOO is a language extension describing the
- * language of the portion of the token in $1 after pattern executes.
- * E.g., if style is 'lang-lisp', and group 1 contains the text
- * '(hello (world))', then that portion of the token will be passed to the
- * registered lisp handler for formatting.
- * The text before and after group 1 will be restyled using this decorator
- * so decorators should take care that this doesn't result in infinite
- * recursion. For example, the HTML lexer rule for SCRIPT elements looks
- * something like ['lang-js', /<[s]cript>(.+?)<\/script>/]. This may match
- * '<script>foo()<\/script>', which would cause the current decorator to
- * be called with '<script>' which would not match the same rule since
- * group 1 must not be empty, so it would be instead styled as PR_TAG by
- * the generic tag rule. The handler registered for the 'js' extension would
- * then be called with 'foo()', and finally, the current decorator would
- * be called with '<\/script>' which would not match the original rule and
- * so the generic tag rule would identify it as a tag.
- *
- * Pattern must only match prefixes, and if it matches a prefix, then that
- * match is considered a token with the same style.
- *
- * Context is applied to the last non-whitespace, non-comment token
- * recognized.
- *
- * Shortcut is an optional string of characters, any of which, if the first
- * character, gurantee that this pattern and only this pattern matches.
- *
- * @param {Array} shortcutStylePatterns patterns that always start with
- * a known character. Must have a shortcut string.
- * @param {Array} fallthroughStylePatterns patterns that will be tried in
- * order if the shortcut ones fail. May have shortcuts.
- *
- * @return {function (JobT)} a function that takes an undecorated job and
- * attaches a list of decorations.
