Converting

To convert my setup to neovim, lua and all that, I need to

Native

For the most part anything using functions and the like can go away. I can use this opportunity to clean things up a little.

For remaps I can define a macro and it should do all of that for me.

I might just pipe all these files into one file, run the macros, delete what I don't need and split that file up again in the end.

undoings

There are some things I want to undo, like the damn i_ that neovim added.

commands

Instead of some of the augroups and stuff i will simply be using commands with some of these things.

  • FF
  • HH for vert help
  • PP for PackerSync

Plugins

I'll switch to Packer, so submodules goes away.

Most packages can go because they are related to languages, which will be handled by treesitter and lsp.

Those that don't go away are:

  • fzf
    • not sure why there are two of them.
  • repeat, might not actually need this one without surround
  • surround, will be replaced by sandwich
  • a bunch of tpope's stuff

subfiles

This will add cleanlyness, but I am not willing to do the whole lua module thing. This is too small for that and I am not using more lua elsewhere yet.

I can still use vim plugins, obviously.

Setup

I have been putting off updating this one for a while. It would be nice to try out the thing with files to keep packages more clean. But barring that I am saving myself the main thing I have been letting slide recently: language server and linter stuff for vim.

For the neovim config files I just put this command, followed by PackerSync and LSP installations.

ln -s <.vim_root_git>/neovim/* ~/.config/nvim/

It is important that we don't just link nvim with neovim, becuase nvim will have plugin files from packer in it. These will be replacing the git submodule files, while packer code in lua is replacing our gitmodule.

I will have to remember to add setups for 'TSInstall all' and whatever LSP requires.

LSP

Ioi this was a rollercoaster so far. None of the guides worked out of the box but I managed to make it work with a mix between a bunch.

for setup

I will need to install all the language servers in order for them to be accessible. I am not sure if I then also need to run :LspInstall for each of them, but I would presume I do. And my plugin.lua doesn't seem to fail if the server is not installed, so that is good.

to remember

It was interesting, when I copied the setup from the readme it kept throwing errors and was't able to install or even uninstall anything. However, those servers that were setup correctly before the error would work fine.

What seemed to work in the end was the following. I would combine the two plugins in one use statement in the corret order (installer first). Then I would add a config between the installer and lspconfig (not sure if it would also work after them, I'll just keep it here).

Now just this would at least clear the warnings and allow me to run :LspInstall. But none of the servers would start unless they were setup. The things is that setting them up inside the packer function would break everything and lead to all those errors. So I simply don't. I run lspconfig.<pluginname>.setup {} at the bottom.

And this took me several hours to fix up.

Also, and this didn't take me that long to figure out, but nice to know, people have talked about how to disable the undefined global vim and undefined global use inside your vim configuration. But you know what, sumneko lua is better than that. You can use a code action Mark vim as defined global on one of the warnings and it creates a .luarc.json inside your directory. It is much simpler than fiddling with your lua files and having the lsp-config and the lsp-installer interfere.
