[Boost-users] [xpressive] treating special literals as non-regex

Hello *,

I ran into a problem, that I use some regex to split a string by some
delimiters. My interface to the outer world is non-regex. A user can pass
anything like delimiter. E.g. $d$ can be a valid delimiter.

If I use sregex_token_iterator with regex created as: as_xpr("$d$") are $
treated as regex special characters and I have to escape them or can I
safely use them in this context? If I have to escape the special characters
is there any helper function like protect("$d$").

Many thanks for help,
Ovanes
