  • nvim-tree plugin --- file manager
  • barbar plugin --- toast hint
  • telescope --- global search
• LSP-config
  • nvim-lspconfig --- use mason-lspconfig instead
  • nvim-lsp-installer --- use mason instead
  • null-ls
  • mason-lspconfig --- lsp configuration
• Markdown
  • markdow-preview
• Git
  • gitsingns --- show different label in vim

1. On Path ~, exec command git clone --depth 1 https://github.com/wbthomason/packer.nvim\ ~/.local/share/nvim/site/pack/packer/start/packer.nvim to install packer.nvim
2. Go to vim to exec

:w
:PackerSync
:luafile %

ensure that you use nerd-font in terminal

1. install brew tap homebrew/cask-fonts brew install --cask font-hack-nerd-font
2. iterm font switch to 'Hack Nerd Font Mono'

If you use mac, <A-.> means <ESC-.>. And you shoud hold key for a while.

ensure fd(replace find command) & ripgrep(replace grep command) has installed.

1. brew install fd
2. brew install ripgrep

use nvim-lsp-installer instead. after install nvim-lspconfig plugin, ensure use right node version. 1. check current node version. nvm version nvm default [version>15] nvm use [version>15] 2. install language server e.g. pyright npm i -g pyright 3. load configuration see github -> https://github.com/neovim/nvim-lspconfig 4. open a py file to check Lsp is installed successfully input :LspInfo

You can usc nvim-lsp-installer to install certain language server, which has already support formatting.

To run built-in sources, the command specified below must be available on your $PATH and visible to Neovim. For example, to check if stylua is available, run the following (Vim, not Lua) command:

" should echo 1 if available (and 0 if not)
:echo executable("stylua")

if not, you can use homebrew to install.

e.g. brew install stylua

There's two details you should notice.

1. set certain language server

require("mason-lspconfig").setup({
    ensure_installed = {
        "lua_ls",
        "bashls",
        "emmet_ls",
        "pyright",
        "clangd",
        "kotlin_language_server",
        "jdtls",
    },
})

2. read mason-lspconfig help documentation to bind key in certain server

require("mason-lspconfig").setup_handlers({
    function(server_name)
        require("lspconfig")[server_name].setup({
            on_attach = common_on_attach,
        })
    end,
})

Pay attention to keymap filetype code.

vim.api.nvim_create_autocmd("FileType", {
	pattern = "markdown",
	group = vim.api.nvim_create_augroup("MarkdownSnippet", { clear = true }),
	callback = function()

	end,
})

Do not remap '[c' & ']c', beacause it's default git navigation key in nvim
