Open Nvim Tree on startup while preserving vim-startify

[unayakani]

How do I open nvim tree on startup along with vim-startify?

I use Neovide

I tried this:

autocmd VimEnter *
            \   if !argc()
            \ |   Startify
            \ |   NvimTreeOpen
            \ |   wincmd w
            \ | endif

But it doesn’t seem to work. Isn’t this a simple question and shouldn’t it be easy to find? I read the nvim tree docs but no luck. I’ve been trying from hours. I also saw this issue but I haven’t been able to open startify along with nvim tree on startup. Thankyou.
(And also, I wanted to know how to make nvim tree startup on a specific directory after we have solved the above issue. Thankyou)

Quick update.:
It just clicked to me right now, so now I have temporary fix:

autocmd VimEnter * :Startify
autocmd VimEnter * :NvimTreeOpen

I still do need a permanent thing to put in the nvim-tree.lua config

Now I gotta figure out how to throw the cursor to the other window coz | wincmd p isn't working

autocmd VimEnter * :NvimTreeOpen

It might be easier to use the option :help nvim-tree.open_on_setup to do this for you.

See :help nvim-tree.open_on_setup_file

Open on setup file didn't work earlier. I'll got through the help files for sure. Thanks.

:h nvim-tree.open_on_setup_file states that "nvim-tree will be focused". I didn't want that.

Update: open on setup and open on setup file; both aren't working

[unayakani]

Adding open_on_setup = true and ignore_buffer_on_setup = true did the job!!

[unayakani]

@alex-courtis was partially correct,
Only open_on_setup = true didn't work for vim-startify.
I also had to add ignore_buffer_on_setup = true after that to do the trick.
Here's a part of my new config:

lua << EOF
require("nvim-tree").setup{
  open_on_setup = true,
  ignore_buffer_on_setup = true,
}
EOF

( I still use VimScript 😂 )

[unayakani]

Thanks again @alex-courtis . I had seen the open on setup things before but adding ignore buffer on setup does the trick!

Nothing wrong with that... I'm still using init.vim

It calls lua files when lua is needed for setup etc: https://github.com/alex-courtis/arch/blob/6d681e76b52c7123ce53d18c5fd107cab6739d0a/config/nvim/init.vim#L100

[unayakani]

Nothing wrong with that

I know. Even I call Lua files either with lua << EOF or for single line configs, lua
Just that people seem to be lua-izing everything and I’m just fine with Vimscript. I find vimscript to be easier, too.

@alex-courtis , can you add this solution as a section in the wiki? Looks like forking the repo doesn’t fork the wiki and I have to clone it manually.

[alex-courtis]

Unfortunately there doesn't appear to be a means to open up the wiki repo for direct pushing.

Fortunately, everyone can just edit the wiki directly :)
