[Feature] Show dashboard with directory as first argument

[JSteitz]

In the code, you are already handling files as first argument.
It would be nice, if we could have an option to show the dashboard when the first argument a directory is.

would this also change the working directory? i do this accidentally all the time, actually. it's tricky to get the behavior right so it should definitely be opt in

[goolord]

in my personal config i currently have this relatively complicated autocmd setup to open a file tree when i try to open a directory with nvim

    vim.cmd[[
    autocmd StdinReadPre * let s:std_in=1
    autocmd VimEnter * if argc() == 1 && isdirectory(argv()[0]) && !exists('s:std_in') |
        \ execute 'cd '.argv()[0] | execute 'NvimTreeOpen' | wincmd p | q | endif
    ]]

No, that's not required.

NvimTree has an option to do that for you.
But I prefer not to use it myself. I switched from Dashboard to alpha, and in Dashboard I had an autocmd to that, but I can't make it work with alpha.

After rereading, I understand your comment better.
I only want to show the Dashboard when I open neovim with a directory as argument: nvim /path/to/project.

Just curious if anyone found a way to make this work. I am currently using neo-tree and it shows if I do nvim . or nvim /some/path/ but what I'd really like is to have those commands produce this (I got it by running nvim and then toggling the tree on manually):

@genebean
I do not use alpha-nvim anymore.
Instead I have this little snippet in my init.lua:

-- Set workdir if argument is provided
if vim.api.nvim_buf_get_name(0) ~= '' then
  -- get current opened buffer (first argument with `nvim /path/to/dir/or/file`) 
  local path = vim.api.nvim_buf_get_name(0)
  -- workdir is either the directory itself or the directory where the file is
  local workdir = vim.fn.isdirectory(path) == 1 and path or vim.fs.dirname(path)

  if vim.fn.isdirectory(path) == 1 then
    -- remove directory buffer to get an empty buffer
    -- to show neovim info you need a single empty buffer
    vim.cmd([[bdelete %]])
  end

  -- set workdir which allows creating/navigating in the directory (used by telescope/etc...)
  vim.loop.chdir(workdir)
end

If this is not enough, you can use vim.cmd("NvimTreeOpen") after removing the directory buffer to show neotree.
The same applies to alpha-nvim if it does not show itself.

@JSteitz Your suggestion lead me to this fix (I added it to my alpha config)

vim.cmd('autocmd User AlphaReady Neotree show')
