vim.keymap.set vs. vim.api.nvim_set_keymap

  • vim.api.nvim_set_keymap comes from the v0.5 days and has some downsides

  • use vim.keymap.set, which is Lua exclusive interface designed to work around nvim_set_keymap issues.

On file explorers

Neovim comes by default with netrw file explorer. I tried it and didn't like it. However it has powerfull over-the-network editing and browsing capabilities. Which I'm not interested currently.

So I analyzed several and finally decided for neo-tree.

My main rule was to choose only from the ones written in Lua. And a secondary rule was for it to have a simple setup. And the third rule, based on my experience with nvim-tree, was that hopefully the plugin doesn't mess much into my configuration. See notes at the end about my grievances and problems about nvim-tree.

List of analyzed plugins

  • NERDTree (vimscript)
  • fern.vim (vimscript)
  • dirvish.vim (vimscript)
  • nvim-tree.lua (lua, but that's the one I was ditching)
  • tree.nvim (C++, overkill, I don't wanna have to compile a plugin if I can avoid it)
  • defx.nvim (python)
  • CHADTree (python)
  • lir.nvim (lua) This one's pretty simple and claims not to mess with my filesystem. I didn't try it because I liked much more the looks of neo-tree, however this one would have been my second choice.
  • telescope-file-browser.nvim (lua) Telescope is pretty cool, I didn't installed this one, but it would be a contender should I revise file navigators again.
  • neo-tree.nvim (lua)

nvim-tree issues

I don't like that:

  • doesn't came with sane default mappings for opening it, but it comes with other key mappings that mess with my configuration.

  • if I have a vertical split and from the nvim-tree window I try to open another file, it asks me "Pick a window". And I don't know what to put. Tried numbers, the file name, the mouse, but nothing worked, so I cannot open from it a file into a vertical split.

  • comes with a mapping for <c-t> to open a new tab, I changed that mapping but nvim-tree kept hold on the mapping and mine didn't work.

  • I tried to issue the help, which documentation says it's brought via g? key combination, but didn't work for me.
