[file rename] run :edit to reload filetype when buffer is loaded and renamed

[ignamartinoli]

Is your feature request related to a problem? Please describe.
It's not really a bug. But it would be cool that if somebody renames a file to a different filetype, nvim-tree.lua could check if there was an LSP or a nvim-treesitter module to load.

Describe the solution you'd like
After renaming, try to activate nvim-treesitter and LSP

Describe alternatives you've considered
Turn it on myself ahah

Do you mean just running :edit on the buffer that was renamed ? This way the filetype would change ?

[ignamartinoli]

Yes, that would trigger nvim-treesitter syntax highlighting.

For the LSP, I just made a test and it's bit trickier.
If, for example, you had a Java file, and were to rename it to a *.py, after running :edit you would have both Java and Python LSPs running.

I'm not sure if it's possible to fix that from nvim-tree.

[kyazdani42]

I'm not sure, this sounds to me this is the lsp client job, not nvim-tree. At least triggering an edit if the buffer exists for a renamed file would be enough, the rest should be left to whatever plugin uses filetype detection. I'm renaming this since its unrelated to other plugins but more related to neovim internals.

[ignamartinoli]

Yea, I agree on that.
I just forked and I'm working on fixing this, can I PR when I accomplish it? I want to learn to do it

[kyazdani42]

go for it :)

This would be very useful for a pattern I often follow:

• a create a new file
• add #!/bin/sh to the first line
• . !chmod 755 ...
• :set ft=sh

We could adapt this solution to automate that last step.

@kyazdani42 I added this line on rename-file.lua

vim.cmd [[silent! edit]]

But it doesn't work like when the user runs the command himself, I read the man page and tried different variants, do you happen to know where I'm missing the point?

[kyazdani42]

you need to edit after reloading the buffers

[ignamartinoli]

@kyazdani42 I'm really sorry. I surrender ahaha, I can't fix it. If you're able I would love to see how it's done

[kyazdani42]

no worries :) i'll fix this then

[ignamartinoli]

Thanks!
