Title: Change in vim cua regex
Post by: b on November 19, 2015, 08:37:36 pm

It appears that in the vim CUA command mode that the regex parser is inconsistent or changed.
(v20.0.0.12/Hotfix 1)

I'm changing a bunch of printf functions to a debug function, but I don't want to change the fprintf routines

I can perform a search as /\<printf and it finds the matches
However, if I try to search and replace, it finds no match  :%s/\<printf/debug/

Yet, :%s/\bprintf/debug/ works (Perl regex).  But if I try searches with the Perl regex /\bprintf does not.

It appears that one is still using the vim regex, and the other is using the perl regex.

Is this a bug or is there some other configuration change I need to make them consistent?

\< is not longer supported. use \o< instead. This change was made to improve compatibility with Perl.

/\bprintf works for me. No change here.

I'm two for two today.   Now /\b<string> is working where I had tried it several times before and it hadn't.   

Thanks for the alternate.  What is the \o ??  old?

\o does not stand for old. It stands for option. We simply needed a way to add extensions without conflicting with Perl options or messing up how to fully escape a regex string (can't use \ followed by non-alpha character).
