プログラミングする時の一番大事な道具はエディタ。僕は neovim を使っていて、その設定をまとめた。

パソコン通信。それはそうと、neovim が emacs 化している。

vim の中でターミナルを使うし、

メールもできるよ。

完全に自己満足の世界…

reset all config

rm -rf ~/.config/nvim
rm -rf ~/.local/share/nvim
mkdir -p ~/.config/nvim/lua/plugins

init.lua

ディレクトリはこんな感じ。

.config/
├─ nvim/
│  ├─ init.lua
│  │  ├─ lua/
│  │  │  ├─ init_lazy.lua
│  │  │  ├─ options.lua
│  │  │  ├─ plugins/
│  │  │  │  ├─ init.lua
│  │  │  │  ├─ {plugin}.lua // whatever you need

これは、 ~/.config/nvim/init.lua で、みての通り、他の設定をまとめているだけ。neovim は、lua 言語(でも)設定する。

require('init_lazy')
require('options')
require('keymaps')

init_lazy.lua

lazy.nvim is the new plugin manager

-- setup lazy

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"

    "--filter=blob:none",
    "https://github.com/folke/lazy.nvim.git",
    "--branch=stable", -- latest stable release
    lazypath,
  })
end
vim.opt.rtp:prepend(lazypath)

vim.g.mapleader = " " -- Make sure to set `mapleader` before lazy so your mappings are correct

require("lazy").setup("plugins")
