Add support for glob patterns

[bscuron]

:Dirbuf now accepts glob patterns. For example :Dirbuf ~/Documents/*/.txt will find all of the text files in the ~/Documents directory. :DirbufNext and :DirbufPrev can be used to iterate through the glob pattern files.

When iterating through the files, at the bottom of the screen a message is printed indicating the amount of files and the index of the current file in the matched files. (1/16), (1/20), etc.

This is an interesting feature. What's its use-case? Personally, I've never wanted to iterate through a list of files matching a certain glob, so I'm interested to hear when you want to

[bscuron]

One use case would be if you have to perform some directory specific actions on multiple directories that you know matches a glob pattern. For instance, say I want to delete a file inside multiple directories that contain a .git/ directory. So I would use the glob pattern ~/Documents/**/.git, delete what I need to, then use :DirbufNext and :DirbufPrev to quickly jump to the next result.

Netrw has similar commands (:Nexplore and :Pexplore)

Another useful case is if you are trying to edit a file you don't know the exact name of, but might know its file extension. You can use a glob pattern to match all files with a certain extension to browse the filesystem and see which file you are looking for.

Sorry for the slow reply! I've been in starting a new job and moving.

Did you mean to leave this PR closed?

Also in response to these changes, I think this feature would be better served by :h arglist. So to search for multiple files you could do :argadd ~/Documents/**/.git instead of :Dirbuf ~/Documents/**/.git and then navigate with :next +Dirbuf\ % and :prev +Dirbuf\ % instead of :DirbufNext and :DirbufPrev. The only real drawback I see here is that you lose the behavior where running :Dirbuf ~/Documents/**/.git automatically opens the first glob matched and highlights. But IMO I think it's more composable and intuitive to keep the behavior of :Dirbuf simple so it doesn't accidentally do unexpected things.

I'd be happy to accept an addition to :h dirbuf-faq mentioning this, ideally with a small 2-3 line config snippet with custom commands which do this. But in its current state, I'm not interested in merging this PR

I can understand how it can make the use case of :Dirbuf too confusing. That is one of my problems with many plugins (adding too many features).

I will try using argadd and see how that works. Thanks for the suggestion!

Also it is fine to leave this pr closed!

A workaround that I am currently using is:

" Find
command! -nargs=+ -complete=file Find set errorformat=%f | cgetexpr glob(<q-args>) | copen | cc | 
nnoremap <leader>f :Find <glob pattern here>

This will populate the quickfix list with the files and directories that match the glob pattern. This way you can use :cnext and :cprev to iterate through the matches.
