// Regex pattern below is automatically generated by regexpPrecederPatterns.pl

// Do not modify, your changes will be erased.

// CAVEAT: this does not properly handle the case where a regular

// expression immediately follows another since a regular expression may

// have flags for case-sensitivity and the like. Having regexp tokens

// adjacent is not valid in any language I'm aware of, so I'm punting.

// TODO: maybe style special characters inside a regexp as punctuation.

/**

* A set of tokens that can precede a regular expression literal in

* javascript

* http://web.archive.org/web/20070717142515/http://www.mozilla.org/js/language/js20/rationale/syntax.html

* has the full list, but I've removed ones that might be problematic when

* seen in languages that don't support regular expression literals.

*

* Specifically, I've removed any keywords that can't precede a regexp

* literal in a syntactically legal javascript program, and I've removed the

* "in" keyword since it's not a keyword in many languages, and might be used

* as a count of inches.

*

* The link above does not accurately describe EcmaScript rules since

* it fails to distinguish between (a=++/b/i) and (a++/b/i) but it works

* very well in practice.
