为什么 Neovim
VS Code 很棒，但当项目变大、插件变多时，内存占用和响应延迟会逐渐显现。Neovim 基于 Lua 的全新插件生态让终端编辑器焕发新生：启动<50ms，内存<100MB。
Lazy.nvim 插件管理
-- ~/.config/nvim/lua/plugins/init.lua
local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
vim.opt.rtp:prepend(lazypath)
require("lazy").setup({
-- 颜色主题
{ "catppuccin/nvim", name = "catppuccin", priority = 1000 },
-- 文件树
{ "nvim-neo-tree/neo-tree.nvim", dependencies = { "nvim-lua/plenary.nvim" } },
-- 模糊搜索
{ "nvim-telescope/telescope.nvim", dependencies = { "nvim-lua/plenary.nvim" } },
-- LSP 支持
{ "neovim/nvim-lspconfig" },
{ "hrsh7th/nvim-cmp", dependencies = { "hrsh7th/cmp-nvim-lsp" } },
-- Treesitter 高亮
{ "nvim-treesitter/nvim-treesitter", build = ":TSUpdate" },
})LSP 与自动补全
-- 自动安装 language servers
require("mason").setup()
require("mason-lspconfig").setup({
ensure_installed = { "lua_ls", "tsserver", "rust_analyzer", "gopls", "pyright" }
})
-- nvim-cmp 配置
local cmp = require("cmp")
cmp.setup({
mapping = cmp.mapping.preset.insert({
["<Tab>"] = cmp.mapping.select_next_item(),
["<CR>"] = cmp.mapping.confirm({ select = true }),
}),
sources = { { name = "nvim_lsp" }, { name = "luasnip" }, { name = "path" } },
})生产效率 Tips
