Thanks a bunch. It's in svn now. I added some remarks on usage to the 
top of the file, maybe you want to review and correct these. I also had 
to rename the file to gpure.lang, since there's already another 
pure.lang file for Simon's hightlight program. (That's the program I use 
to beautify the examples on the Pure website. Unfortunately, that 
program doesn't like it if the language definition file is named 
differently; Gedit doesn't seem to have a problem with that. Boy I hate 
it when programs like these use generic filename extensions like .lang 
or .xml, Kate is no better either.)

The following regex should properly describe Pure numbers, except for 
the case of a floating point number starting with a decimal point. That 
doesn't seem to be possible without breaking '..', since those 
highlighting engines don't seem to support left context; at least I 
couldn't figure it out.

0[xX][0-9a-fA-F]+L?|\d+L?|\d+(\.\d+)?([eE][\-\+]?\d+)?|\d+(\.\d*)?[eE][\-\+]?\d+

Unfortunately, that regex makes Kate go bonkers, don't know why, so I 
stick with Kate's predefined Int/Float highlighting rules for now. Maybe 
you have more luck with that. :)

Thanks again for that gedit highlighting. I guess we support the most 
important non-Windows editors now.

Cheers,
Albert
