Re: Regular Expressions: How to restrict match extension to the first occurrence?

Dear Christian,

as requested I explain my test of the suggested solutions.

I tried three regular expressions and used
:set hlsearch
to see the matched region.

The original full line is
glm::something lmg::else

/\<.\{-}::
as well as
/\<..\{-}::
and
/\<.\{-1,}::
all matched, and highlighted,
glm::something lmg::

The only thing after starting vim -U NONE -u NONE was to
:set nocompatible
and
:set hlsearch

This result could be obtained on vim 7.4 (MacVim) and vim 7.3 (debian wheezy).

Does this answer your question?

Cheers and many thanks!
