User-named character classes?
Posted: Sat Dec 31, 2011 4:09 am
Suppose I wish to match for a pattern that [e.g.] consists of any UTF-8 character in the Czech alphabet (in either case).
See http://en.wikipedia.org/wiki/Czech_alphabet
Excluding the "Ch" diglot, a Perl pattern that does this would be as follows:This is equivalent to the shorter pattern The latter will not work when entered as a simple Perl pattern in TextPipe, so one has to use the more complicated one with all the hexadecimal codes.
It would be much simpler if there was a facility to define user-named character classes, such that a much shorter pattern name can be used, perhaps by extending the POSIX notation such that would be equivalent to the above pattern.
I can't use captured text and store it in a global variable, as the files to be processed will not contain it.
Am I forced to resort to VBScript, or is there a simpler more open method?
