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"
sorry for my late answer on this issue! :-)
I'll try to take a look at this problem, probably your solution should
be fine :-)
cheers

I have been doing some additional work on it and made a few modifications:
include "c_comment.lang"
# highlight the flags vvvvvv
regexp = '/(\\.|[^\\/])+/[gim]*(?![*/])'
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"

type = "int|byte|boolean|char|long|float|double|short|void"
include "symbols.lang"
cbracket = "{|}"
# in JavaScript, the '$' is valid in an identifier
vardef FUNCTION = '([[:alpha:]]|_|\$)[[:word:]\$]*[[:blank:]]*(?=\()'
