TLMDRegExpr support for negative lookahead?

Albert Wiersch

Had a user comment that a regular expression they were using with positive lookahead worked, but one with negative lookahead didn't.

It seems the regular expression engine in LMD SyntaxEdit only supports positive lookahead with the others not supported: "Negative lookahead as in q(?!u) is not currently supported. Positive lookbehind as in (?<=u)q is not currently supported. Negative lookbehind as in (?<!u)q is not currently supported."

Not a big deal for most of my users but any chance of an upcoming update to the regular expression engine so it is supported?

We did not planned to extend reg-exp engine. And mentioned features are not supported because they are complex and requires non-trivial implementation. At the same time, they are not needed for current schemes.

OK, I understand.
