Hangs on saving

[dvogt23]

After install nvim-tree nvim hangs on saving 🤔 somtime just 2sec, sometime more ...

any idea? whats info need for debug?

[kyazdani42]

i'm really not sure what this is about. Are you sure this comes from nvim-tree ? Your tree is not even opened so this seems strange to me

[dvogt23]

Yes, just after the include with the packer this happens 😞 so unfortunately yes ... after dropping this plugin, everything looks fine. Can I help with some additional info?

[kyazdani42]

hm, maybe a minimal init so i can reproduce ? and your neovim version :)

[dvogt23]

sure thing :) nvim NVIM v0.5.0-dev+nightly-105-g66f9dd3c6

i cannot reproduce the lag :/ seems weird that this is nvim-tree related, could you disable the ligne 15 in tree.vim and tell me if the lag is still here ? If not, this cannot be nvim tree related.

Same here, happens when git integration is enabled. Try to disable it (vim.g.nvim_tree_git_hl = 0).

thanks! Thats it ... thanks @kyazdani42 for investigation and this great plugin 🥇 🙏🏾

[kyazdani42]

git integration could indeed slow down the plugin as it's using cli commands (and i'm not sure how fast cli commands happen but they are usually slower than libraries). If something like https://github.com/libgit2/luagit2 can be integrated at some point that would be nicer i suppose

[Samyak2]

I have the same issue with everything updated to the latest versions. Saving a file pauses everything for 1-2s. Opening neovim is slow too (~1.5s), but it's not captured by --startuptime. Removing nvim-tree fixes the slowdowns.

Also worth mentioning that this happens when opening neovim inside a large repository (even without opening a file). Opening neovim in my home dir or my config dir does not show the same behaviour.

vim.g.nvim_tree_git_hl = 0

This did not work for me, it was already disabled. Is there any other setup parameter that makes use of CLI commands?

I'll try making a minimal reproducible config. I'm on NVIM v0.5.0-dev+1357-g192f89ea1

There is also nvim_tree_show_icons, you should disable git.

[Samyak2]

That fixed the delay on save. Thank you!

Although the lag on startup still exists.

[kyazdani42]

lag on startup i cannot reproduce, but it might be related to you shell. if you set shell=/some/shell/without/config, does the lag still exists ?

[Samyak2]

I tried setting shell to /usr/bin/bash --noprofile --norc, it did not change the startup time in any way. Takes nearly ~10s inside a large repo.

Should I open a new issue for this?

[Samyak2]

I also tried opening neovim from a fresh shell with all environment variables reset (env -i bash --noprofile --norc), the lag still exists.
