Hi all- &a &B &! 'c' 'D' '!' "e" "F" "@" ^G ^h ^+

within the match field of a language grammar.

If I use the search dialog box, this regexp will work for characters enclosed in single apostrophes:

((?<=^)|(?<=\s))(([&^]\S)|('\S'))(?=\s)

But it doesn't work when I get it into the match field, I suspect because of the framing apostrophes, as in:

{ name = 'constant.character.forth'; match = '((?<=^)|(?<=\s))(([&^]\S)|('\S'))(?=\s)'; },

Any ideas about what I'm doing wrong, or how I can solve my trouble?

Maybe this could help: E.g. ("|\x{27}) for " or '

27 is the hex code for a '

If there is no need to distinguish between e.g. quoted.double and quoted.single in your language grammar you could use this for instance:

match = '("|\x{27})([[:alnum:]]+)\1';

will match 'STRING' or "STRING" but not "STRING'

\1 contains the match of the first regexp group ("|\x{27})

Hi Hans-

I appreciate this and your following message. For some reason, I thought hex codes were entered as \x27 and not the \x{27} as you suggest. They work fine now...

AFAIK TM uses internally the Oniguruma regexp engine with wide hex chars: \x{7HHHHHHH} wide hexadecimal char

To be honest I've never read this. Thanks for pointing this out.
