Update file handler/buffer after move/rename

[gegoune]

Currently renaming a.lua to b.lua leaves me with open buffer named a.lua (saving which recreates a.lua on filesystem) and no b.lua gets opened.

Expected behaviour is such that a.lua buffer gets removed and b.lua is opened in its place (not with the same buffer number, but 'instead').

There is also a related error message shown when the cursor went back to the no-longer-exist buffer(i.e. a.lua in the example) on neo-tree close. While it is not harmful but definitely related.

[gegoune]

Without checking, afair, it's regular (neo)vim's messages saying that file for that buffer no longer exists. It's not an issue in itself as much as it is product of not updating/removing that buffer by neo-tree (which this issue is about).

This is now working in main and will be in the next release.

@cseickel: This causes an error. The renamed buffer is not writable anymore.

E5108: Error executing lua: /Users/ningwang/.config/nvim/init.lua:35: Vim(write):E13: File exists (add ! to override)
stack traceback:
        [C]: in function 'cmd'

:( waiting for the fix. Now it's a fake buffer that got renamed but no writable.

[cseickel]

I'll fix it, but to be clear it's still writable and not a fake buffer at all. You just have to add the ! to your write the command the first time you write it.

:w!

So the E13 error issue is resolved, and I also realized that previously there was no handling for renaming buffers in a directory that was renamed, that was fixed too.

I did find a new bug related to cut/pasting files. I'm not sure if it's related to this or not but I'm investigating that right now.
EDIT: That was unrelated, but it's fixed now too.

FYI I was able to implement this functionality for tsserver. I added the following handler https://github.com/Gelio/ubuntu-dotfiles/blob/d5f693db0e5afd10efacb3269f3a96bf3bade834/install/neovim/stowed/.config/nvim/lua/plugins.lua#L116-L134 for the rename and move neo-tree events https://github.com/Gelio/ubuntu-dotfiles/blob/d5f693db0e5afd10efacb3269f3a96bf3bade834/install/neovim/stowed/.config/nvim/lua/plugins.lua#L176-L183

It may be worth adding this snippet to the documentation or the codebase so others can easily copy/require it and use it themselves.

With this snippet, renaming/moving a file or directory in neo-tree automatically updates import paths in TypeScript.

Keep in mind that the tsserver language server needs to be running in the background for this command to run. This is easy enough, though. Just open any TypeScript file and then your subsequent renames/moves will automatically update imports in other files.

EDIT: I've just noticed I should have posted this in #47 rather than here. My bad

🤯 You are amazing @Gelio! Thanks for sharing this! I'll link to his comment in the wiki for now.
