What's the \V doing? #1

Closed niko closed 11 years ago

Hi,

thanks for this nice plugin. I have a question though. I couldn't figure out what the \V is doing here:

https://github.com/thinca/vim-visualstar/blob/master/plugin/visualstar.vim#L50

I use your plugin in conjunction with vim-ag and AgFromSearch and the \V interferes with AgFromSearch. I removed the \V from visualstar and it continued to work just as before as far as I can tell. Hence the question… can you help?

Regards, Niko.

\V is very nomagic. See :help /\V. This plugin searches the selected string as plain text, not regexp. \V can escape all regexp character except \\.

And, Vim's regexp differs from Perl's regexp. vim-ag is this? https://github.com/epmatsw/ag.vim/blob/master/plugin/ag.vim#L72 Essentially, this plugin should convert \V. (However, if it tries to do this seriously, it may be very difficult.)
