Help Lazy Loading Vim-Dirvish

[unrealapex]

How would one go about lazy loading vim-dirvish? I can set it to load on keymap but it does not load on Netrw/when Neovim is opened with a directory(nvim .):

{
  'justinmk/vim-dirvish',
  lazy = true,
  keys = '-',
  ft = 'netrw'
}

Maybe something like the below? Haven't tested it

{
  'justinmk/vim-dirvish',
  keys = '-',
  ft = 'netrw',
  init = function()
   if vim.fn.argc() == 1 and vim.fn.isdirectory(vim.fn.argv(0)) then
     require("lazy").load({plugins = {"vim-dirvish"}})
    end
  end
}

This is how I do it for neo-tree:

init = function()
    vim.g.neo_tree_remove_legacy_commands = 1
    if vim.fn.argc() == 1 then
      local stat = vim.loop.fs_stat(vim.fn.argv(0))
      if stat and stat.type == "directory" then
        require("neo-tree")
      end
    end
  end,

Thank you for sharing Folke. My plugin spec handles something that you might want to consider: opening Neovim with multiple files. vim.fn.argc() == 1 evaluates as false if more than one file is given as a command line argument(nvim foo.lua bar.lua). I think the logic you use for directory validation is cleaner so I will try to implement it. Do you think I could check if the file arguments are directories using a single line? AFAIK Lua does not have a map() function.

right, good point!

@unrealapex, in your code snippet, why do you need the following lines？

        else
          file_args_are_dir = false

With these lines, you seem to only care about whether the last checked argument is a directory? Say I provide two arguments to vim, and the first one is a directory. In you for loop, you check the first argument, and set file_args_are_dir to true. Then when your code inspects the second argument, you find it is not a directory, then your code set file_args_are_dir to false. The end result is that vim-dirvish is not loaded in that case. I think you meant to remove the above two lines in your snippet.

Indeed I did. Thank you for pointing that out.
