Error detected while processing CursorMoved Autocommands

[sparkbuzz]

Since this morning I'm getting the error from alpha_nvim below when starting Neovim, and I open NvimTree. I thought this might be related to some changes I made, so I rolled back to my master branch. Error is still there, seems it started since I last ran :PackerSync

Error detected while processing CursorMoved Autocommands for "":
E5108: Error executing lua ...are/nvim/site/pack/packer/start/alpha-nvim/lua/alpha.lua:490: Cursor position outside buffer
stack traceback:

...are/nvim/site/pack/packer/start/alpha-nvim/lua/alpha.lua:490: in function 'move_cursor'
[string ":lua"]:1: in main chunk

Any ideas as to what might be causing this?

I git-bisect-ed nvim-tree.lua and found this bug is present since https://github.com/kyazdani42/nvim-tree.lua/commit/6da74679449897dd95eaecaefe8dea80fc7eb3de (https://github.com/kyazdani42/nvim-tree.lua/pull/967)

I git-bisect-ed nvim-tree.lua and found this bug is present since kyazdani42/nvim-tree.lua@6da7467 (kyazdani42/nvim-tree.lua#967)

I can confirm.

Recently I too got this same error, I thought I broke my config somewhere, cause I update it almost everyday, Is this a alpha.nvim bug? or nvim-tree bug?

[goolord]

here's the problem afaict

• autocmd <buffer> CursorMoved is called
• vim.api.nvim_get_current_win() is called, but between the event being fired and this call some other plugin changes the active window
• nvim_win_set_cursor can now place the cursor outside of the active buffer

even if we thread the actual alpha window here instead of calling vim.api.nvim_get_current_win https://github.com/goolord/alpha-nvim/blob/1cea4543c11c89bd8ce6a2bd3cb1dceff4e3cfde/lua/alpha.lua#L484-L487, buggy behavior would persist since the problem is fundamentally that the active window is allowed to change inbetween a CursorMoved event being fired and finishing

personally, i'm just going to pin nvim-tree to a working commit in my config.

in https://github.com/kyazdani42/nvim-tree.lua/issues/983 users of vim-startify and dashboard.nvim are also encountering this bug, so I think it's fair to say it's a nvim-tree bug

i'll leave this open though, since i'm sure there's a huge overlap between 'people who use alpha' and 'people who use nvim-tree'

seems to be fixed now in https://github.com/kyazdani42/nvim-tree.lua/commit/f7a6ddb72086bb44105864128ebf9943ac0325c1, nvim-tree guys work fast :9
