How to determine that this is not the beginning of a comment?

Question

Regular Expressions

Hello!
I am writing my own code highlighting script. How do code editors determine that this ( library/*.js ) is not the beginning of a comment, but part of a URL?

/* Комментарий */
wp_enqueue_script('Name', get_template_URL() . '/library/*.js', false, '0.0.0', false);

I can't think of a suitable regular expression.
Thank you!

If in a line, then not a comment, i.e. if there is an open but not yet closed quote (' or "), then it is not a comment.
