[PROPOSAL] Migration to ripgrep about tmux-copycat HOT 3 OPEN

Hi, I hope this won't sadden anyone but in general I'm not in favor of this. grep performance is not critical to this plugin.

The speed / slowness comes mostly from bash and sending commands to tmux.

from tmux-copycat.

I can anticipate some concerns about portability, but I can imagine that this might have some performance benefits, given rg's performance in general.

I always have ripgrep installed on all of my systems, so I decided to give it a try. The only really tricky piece is that rg always uses extended regular expressions, so there are two changes required besides substituting rg for grep.

If you'd like to try the ripgrep version you can just uninstall tmux-plugins/tmux-copycat and then install therealpxc/tmux-copycat (I'm not sure that just replacing one with the other and reloading tmux will work right.).

If someone would like to write up some performance tests so that we can more objectively identify how much improvement there is, if any, that would be great.

@BogBel, I think it would be really helpful for this issue if you could expand the title and description to make it clear why someone might want this change, why it should be considered safe, etc.

I think that if we just modify the patterns to assume extended regular expressions, so that tmux-copycat can prefer rg but instead use grep -E when it is available, we can add preferential ripgrep support and retain the relative portability that tmux-copycat currently enjoys.

Is there any developer interest in merging such changes? I'm happy to open up a pull request for further discussion if so.

Actually I agree.. rg might be a bit of a overkill here.. Also are we using basic regular expressions or extended regular expressions here?
