Source-highlight currently does not highlight JavaScript regular
expression literals. http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Reference:Global_Objects:RegExp I am wondering what would be the best way to highlight these? This is what I came up with: include "c_comment.lang" # # Pattern for matching regular expression literals: # The negative lookahead at the end protects against cases like this: # var foo = a / b; /* foo is the quotient */ # Still fooled by things like this: # var foo = a / b / c; # var foo = a / f('foo/bar'); # regexp = '/(\\.|[^\\/])+/(?![*/])' include "number.lang" include "c_string.lang" keyword = "abstract|break|case|catch|class|const|continue|debugger|default|delete|do|else|enum|export|extends|false|final|finally|for|function|goto|if|implements|in|instanceof|interface|native|new|null|private|protected|prototype|public|return|static|super|switch|synchronized|throw|throws|this|transient|true|try|typeof|var|volatile|while|with" include "symbols.lang" cbracket = "{|}" include "function.lang" _______________________________________________ Help-source-highlight mailing list Help-source-highlight@... http://lists.gnu.org/mailman/listinfo/help-source-highlight |
