# Vim Plugins

Although Vim already provides very powerful features, a few good plugins can make your work even more efficient.

## Install Plugins

If you want to install Vim plugins manually, you need to complete the following steps (it is not recommended to install manually, please refer to the [Plugin Management](#plugin-management) content below):

1. Create the `.vim` folder

```bash
cd ~
mkdir .vim
```

2. Create the `bundle` folder in the `.vim` folder

```bash
cd .vim
mkdir bundle
```

3. copy or clone the plugin to the `bundle` folder

```bash
cd bundle
git clone <repository-url>
```

*Note: If the plugin does not have a git address, you can also create the relevant folder directly and place a `.vim` file in it.*

4. Edit `runtimepath`

By modifying the `runtimepath` property, you can let Vim find the plugin you want to load. To view the `runtimepath` property, you can use the `:set runtimepath` command

You can enable new plugins by adding the following configuration to `.vimrc`

```vim
set runtimepath^=~/.vim/bundle/<folder>/
" OR
set runtimepath^=~/.vim/bundle/<name>.vim
```

## Plugin Management

When you have more and more plugins, you need a manager to manage Vim plugins. There are several popular plugin managers:

1. [vim-plug](https://github.com/junegunn/vim-plug)
2. [Vundle.vim](https://github.com/VundleVim/Vundle.vim)

I personally prefer vim-plug, and I will briefly introduce this manager below.

## vim-plug Introduction

### Project Address

<https://github.com/junegunn/vim-plug>

### Install

[Download plug.vim](https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim), and put it in the `autoload` folder (usually this folder is located in `~/.vim/autoload/`).

#### Unix

```bash
curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
```

#### Neovim

```bash
curl -fLo ~/.local/share/nvim/site/autoload/plug.vim --create-dirs \
    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
```

#### Windows（PowerShell）

```bash
md ~\vimfiles\autoload
$uri = 'https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'
(New-Object Net.WebClient).DownloadFile($uri, $ExecutionContext.SessionState.Path.GetUnresolvedProviderPathFromPSPath("~\vimfiles\autoload\plug.vim"))
```

### Configuration

Add the `vim-plug` configuration to `~/.vimrc`:

1. The configuration starts with `call plug#begin()`
2. Plugin list, starting with the `Plug` command
3. End with `call plug#end()` to initialize the plugin system

* This will automatically enable `filetype plugin indent on` and `syntax enable`. If you don't want this, you can reset your settings after this configuration, for example: `filetype indent off`, `syntax off`

#### Example

```vim
" define the location to save plugins
call plug#begin('~/.vim/bundle')

" Note that single quotes should be used

" Some plugin list

" If the plugin's GitHub address is https://github.com/junegunn/vim-easy-align
" Then you can write like this
Plug 'junegunn/vim-easy-align'

" Or directly give the plugin git address
Plug 'https://github.com/junegunn/vim-github-dashboard.git'

" Use `|` to separate multiple `Plug` commands in one line
Plug 'SirVer/ultisnips' | Plug 'honza/vim-snippets'

" More configuration details can be found on the official website

" Initialize the plugin system
call plug#end()
```

> Restart Vim or reload `.vimrc` and execute `:PlugInstall` to install the configured plugin
>
> The reload command is `:source ~/.vimrc`

### Common Commands
