Description
I am a maintainer forbarbar.nvim, and we have a feature that allows users to adjust theoffset of the tabline when a sidebar (such as nvim-tree) is open.
This works well most of the time, however, recentlya user reported that this does not work when using theOpen At Startup snippets from the wiki. Upon investigation, it appears that this is because nvim-tree does not emit aBufWinEnter event in this case. It is worth noting that when doing:NvimTreeToggle afterward, it does.
Neovim version
NVIM v0.9.0Build type: ReleaseLuaJIT 2.1.0-beta3Operating system and version
6.2.10-arch1-1
nvim-tree version
Minimal config
vim.api.nvim_create_autocmd( {'BufWinEnter','FileType','WinNew','WinResized','WinScrolled'}, {callback=function(event)vim.print(event)end})vim.opt.rtp:append(vim.fn.stdpath('data')..'/lazy/nvim-tree.lua')require'nvim-tree'.setup {}-- auto open nvim-tree when open neovimlocalfunctionopen_nvim_tree(data)-- buffer is a real file on the disklocalreal_file=vim.fn.filereadable(data.file)==1-- buffer is a [No Name]localno_name=data.file==''andvim.bo[data.buf].buftype==''-- only files pleaseifnotreal_fileandnotno_namethenreturnend-- open the tree but dont focus itrequire('nvim-tree.api').tree.toggle({focus=false })endvim.api.nvim_create_autocmd({'VimEnter'}, {callback=open_nvim_tree })
It also happens withtree.open
Steps to reproduce
nvim --clean -u minimal.lua- Observe that a
BufWinEnterevent is not printed on startup for theNvimTreebuffer.
Expected behavior
It follows the event sequence that happens when executing:NvimTreeToggle after startup concludes:
{buf=2,event="FileType",file="NvimTree_1",id=14,match="NvimTree"}{buf=1,event="WinNew",file="",id=14,match=""}{buf=2,event="BufWinEnter",file="/home/iron-e/NvimTree_1",id=14,match="/home/iron-e/NvimTree_1"}You can verify the above by using this snippet:
vim.opt.rtp:append(vim.fn.stdpath('data')..'/lazy/nvim-tree.lua')require'nvim-tree'.setup {}-- start listening to autocmds AFTER vim enter; reduces noisevim.api.nvim_create_autocmd('VimEnter', {callback=function()vim.api.nvim_create_autocmd( {'BufWinEnter','FileType','WinNew','WinResized','WinScrolled'}, {callback=function(event)vim.print(event)end} )end})
Then manually typing:NvimTreeToggle.
Actual behavior
{buf=1,event="BufWinEnter",file="",id=3,match=""}{buf=2,event="FileType",file="NvimTree_1",id=3,match="NvimTree"}-- no ButWinEnter for `buf = 2`
