Has anyone written anything to help compare a string to a regular expression?
[\-+]?[0-9]+
[\-+]?[0-9]+\.[0-9]+
#[0-9A-F]+
[a-zA-z]+[_0-9a-zA-Z]*
The above being expressions for eu's integers, atoms, hex numbers and
identifiers respectively (I think).
I have been trying but getting nowhere fast.
Help me please (Sob Sob). I hope to produce EULEX and EUYACC.
Although at this rate I may work it differently.

In wildcard.e is a wildcard_match function, I think.
You can use '?' and '*' .. however it only returns true or false..

I like regexps too. I even have a Unix book with a full list of how to use
them. Ralf's suggestion of using Wildcard.e may be a fairly good start
though...
I'd start work right now, but there's a snag. My net access gets cut off
(extremely likely anyway) from around the 22nd, so I wouldn't be able to
get a finished product to you... :(
If you want a command line tool (for DOS) that parses text files for
regexps, try looking for sed15x.zip or netsearching for SED. (Stream
EDitor).
Also, LEX (or more likely FLEX) and YACC (o.m.l. BISON) are out there
somewhere, for simpler DOS systems, and of course, there's the infamous
DJGPP (*choke*, huge!) package...

In my last few days on the net, I have room for a witty quote. Irony. :S
