Syntax highlighter usually prefer fast over complete. So the term "crippled" should be used with care. See e.g. http://swtch.com/~rsc/regexp/regexp1.html - Regular Expression Matching Can Be Simple And Fast (but is slow in Java, Perl, PHP, Python, Ruby, ...) - which complains about the typical POSIX spencer implementation also. -- Reini Urban http://phpwiki.org/ http://murbreak.at/ -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
