Re: [TxMt] Better JavaScript functions

You can use alternation: (foo|bar). So combined it'd be:

match = "^\\s*(?:this\\.|(var\\b)?\\s*)([a-zA-Z_]\\w*)\\s*=\\s* 

(function)\s*\(([^)]*)\)";

I used the (?:foo|bar) form to avoid making it a capture. It is btw possible to prefix the expression with (?x) to enter “extended’ mode where whitespace and comments are ignored, so we can pretty print it:

match = "(?x)
    ^\\s*                # begin-of-line + leading space
    (?: this\\.          # literal this.
      | (var\\s+)        # -> or literal var (capture #1)
      |                  # -> or nothing
    )
    ([a-zA-Z_]\\w*)\\s*  # actual function name (capture #2)
    =\\s*                # literal =
    (function)\\s*       # function keyword (capture #3)
    \\(([^)]*)\\)        # the parameters (capture #4)
";

Don't know if you find that more readable or not…

Thanks a lot Gavin, great page! I got the idea from Crockford from the beginning, but this seems a bit more comprehensive.
