Show line number

[desprit]

Is there an option to enable line numbers? Something like in a NerdTree:

" enable line numbers
let NERDTreeShowLineNumbers=1
" make sure relative line numbers are used
autocmd FileType nerdtree setlocal relativenumber

If I manually do setlocal relativenumber in an opened tree it works but I don't know how to make that permanent.

lua require'nvim-tree.view'.View.win_opts.relativenumber = true after nvim-tree finished setting up. But this wont apply automatically and youll need to setlocal relativenumber to have the change be immediate or toggling the tree :)

Ok, thanks. I'll keep using this for now:

func! OpenTree()
    :NvimTreeToggle
    :setlocal relativenumber
endfun
nnoremap <F3> :call OpenTree()<CR>

Maybe line number support will be part of nvim-tree API one day? :)

@desprit There's no need for it to be part of the API. Achieving what you describe here is a pretty common application for auto commands. I would just add an auto command like this:

au BufWinEnter NvimTree setlocal rnu

I can't get this autocommand to work. I also don't know how to call lua require'nvim-tree.view'.View.win_opts.relativenumber = true after nvim-tree setup because there's no require 'nvim-tree'.setup() function. Any suggestions?

Variants I've tried:

autocmd BufWinEnter NvimTree setlocal relativenumber
autocmd BufWinEnter NvimTree set relativenumber
autocmd FileType NvimTree setlocal relativenumber
autocmd FileType NvimTree set relativenumber

I can get it working with wrapper functions around each nvim-tree function call I use, but I would prefer not using that approach.

@sindrets

Has something changed? au BufWinEnter NvimTree setlocal rnu no longer works for me.

[kyazdani42]

require'nvim-tree.view'.View.winopts.relativenumber = true

For others stumbling onto this from Google, this can now be configured in the setup call:

require('nvim-tree').setup({view = {relativenumber = true}})
