  • How in the world do you set up nvim-cmp?
    7 projects | | 23 Dec 2021
    You don't, nvim-cmp sets up you. Jokes aside, I am using completion-nvim. Unfortunately it got abandoned just as Neovim 0.5.1 got released, which contained a breaking change. You can look into the pending PRs to see how to fix it for yourself, just use one of the fixed forks. It really sucks, but unless someone steps up an creates a new completion plugin that's what I am stuck with.
  • How to configure ALE and floating windows?
    4 projects | | 2 Dec 2021
    I couldn't figure out how to change this. I found some options, some of which made an entire split window appear above... that's hideous. I also found this, but that works with lua. How do I even set up these lua scripts? I don't get it. Can I get some guidance? Thanks.
  • How do you deal with poorly documented plugins?
    6 projects | | 31 Oct 2021
    I have tried to move to nvim-cmp since completion-nvim is dead, but for the life of me I cannot figure out how to make it not automatically select the first completion candidate. If I type date and hit to insert a new line, cmp takes as the "confirm selection" key (because I have mapped it that way) and expands the snippet. I only want to confirm a selection if I actually selected something from the menu. completion-nvim may be dead, but at least its author had the courtesy to write down how to use it in complete plain English sentences instead of broken English one-liners. Eventually I gave up and moved back to the old setup.

    That will give you the basics, you should see linter diagnostics and auto omin completion should work. For better auto-completion and snippets you can set up one of the completion- and snippets plugins. Personally I use completion-nvim and Ultisnips. There may be better plugins out there, that's just what I happen to have installed.
  • Auto-completion plugin alternatives?
    4 projects | | 10 Oct 2021
    I recently upgraded from Neovim 0.5.0 to 0.5.1 and LSP autocompletion stopped working. I'm using but it looks like its maintenance could be much better. I'm looking for some alternative but I'm not sure what would be a good choice for LSP. Any recommendations?
  • Any auto-completion plugin that works with nvim appimage 0.5.0 out-of-box?
    4 projects | | 2 Sep 2021
    You should try newer and neovim-only completion plugins... e.g. completion-nvim, nvim-cmp
  • Setup neovim for C language
    8 projects | | 14 Aug 2021
    Here's some setup idea: - packer for package manager - clangd language server - nvim-lspconfig, required for navigator.lua - navigator.lua for enchanced IDE experience. This is a like adding a sugar to coffee. - completion-nvim OR nvim-compe for enchanching autocomplete & dropdown menu suggestion. - nvim-treesitter for better syntax highlighting. - telescope.nvim for amazing extensible & configurable fuzzy finder, you can also use fzf if you want. - Any custom color scheme you want (preferably one that supports tree sitter, like aurora )

    If you look up completion-nvim code frecuency and nvim-compe code frequency you can see that, before that las commit, had a lot of time without any or very changes.
