  • Do I need NeoVIM?
    11 projects | /r/neovim | 7 Dec 2023
    https://github.com/hrsh7th/nvim-cmp This is an autocompletion engine https://github.com/nvim-treesitter/nvim-treesitter This allows NeoVim to install parsing scripts so NeoVim can do things like code highlighting. https://github.com/williamboman/mason.nvim Not strictly necessary, but allows you to access a repo of LSP, install them, and configure them for without you actively messing about in config files. https://github.com/neovim/nvim-lspconfig Also not strictly necessary, but vastly simplifies LSP setup. https://github.com/williamboman/mason-lspconfig.nvim This lets the above two plugins talk to each other more easily.

  • is it possible to limit the size of nvim-cmps autocompletion window?
    1 project | /r/neovim | 18 Jul 2023
    one thing that always annoyed me is how the autocomplete window behaves. when the space below your current line isn't sufficient it just teleports above the line. i know you can set a custom menu direction but i'd much rather have it pop up in a consistent place that is below the current line. the other behavior i dislike is the sizing. it's as big as the longest function in the list which can make the window enormous, to the point where there's almost no place left for the docs window. there aren't really any docs in the example below but i imagine with the little space that is left it'll get troublesome for more verbose docs such as with rust. i'd like to somehow tell nvim-cmp to always pop up below the current line, no matter how long the list is and possibly limit the horizontal size. is that at all possible? i've looked through the nvim-cmp wiki but haven't found an adequate solution. does this go beyond nvim-cmp?
  • Toggling the nvim-cmp documentation window

    Update: This isn't currently supported by nvim-cmp (and in fact it has been a feature request for a bit) and so I did my best and opened a PR that implements it :)

  • [Experimental] Auto find Rust executables for DAP | Linux
    1 project | /r/neovim | 20 Aug 2023
    This is not a robust solution to the problem. I haven't worked on a large Rust project, so I do not know if this is valid for all kinds of Rust projects. Maybe there is a better debugging config setups/plugins out there (simrat39/rust-tools.nvim is one from what I have searched for). I plan to keep using this config, till it breaks; and try and fix it when it does.

    I'd start with nvim-treesitter, nvim-lspconfig, and use rust-tools.nvim as an accelerant. Any remaining advice I'd have is about Neovim but not about Rust. That advice would also be mostly questions of taste for this-or-that decisions.

  • Rust + Neovim setup gotcha
    1 project | /r/neovim | 7 May 2023
    TIL that if you install Rust via Homebrew (like brew install rust), auto formatting (or more specifically, lsp formatting) doesn't work properly. I used both Rust Analyzer and rust-tools) to setup rust lsp and configured it with tons of options, thinking maybe something will work but somehow, one thing never did - auto formatting. This is the command I use for setting up auto formatting via lsp:
