Reindex files in the background

[mahemoff]

Is there any possibility of reindexing in the background, instead of hitting F5 and waiting?

I know this has come up for the original ctrl-p in the past, but can't find it in the issues for this fork. I think it wasn't possible due to Vim's threading model, not sure if anything has changed on that front.

Not an excellent answer to your question, but I've found that by tailoring my wildignore I can get the reindexing time down to a few hundred ms which is a lot less painful than I was used to. I did this by opening the index file in ~/.cache/ctrlp (which might be somewhere else if you've customized it), :sorting the file, and then looking for big globs of files that I don't care about and don't want to index. Then I simply added patterns that matched these files to my wildignore in my .vimrc

Hope this helps!

The best way would be for vim to support file change notifications. I requested the feature at https://groups.google.com/d/msg/vim_dev/oubHkRbdQW0/TZYUUQftAgAJ but no comments yet. Neovim has a discussion about it at neovim/neovim#1380. There was even a PR for neovim neovim/neovim#1791 but is now closed.

If you are okay to install binary built by go, you can do it.

@mattn Thanks, have you tried it yourself with ctrlp? What would go into the vimrc?

Also can I confirm we need to copy autoload/filewatcher.vim to .vim folder? (It's not mentioned in the README)

It's experimental plugin to make sure what we can do with vim. so sorry, it may not be ready to use for this use-case.
