CreateSimpleLexer(List<List<Object>> shortcutStylePatterns, List<List<Object>> fallthroughStylePatterns) 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.

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 '
