# Vim
Vim è un editor di testo molto potente, che può essere ampliato ulteriormente tramite **plugin** vari.
## Plugin Manager
Per poter installare dei plugin è necessario installare prima un plugin-manager.
### Vundle
```bash
git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
```
Dopo aver clonato Vundle sulla propria macchina, inserire le seguenti righe di testo nel file `.vimrc`
```vimrc
" PLUGINS ---------------------------------------------------------------- {{{
" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'
"
" All of your Plugins must be added before the following line
"
call vundle#end() " required
" }}}
```
## Installazione plugin
Installare un plugin è molto semplice, basta aggiungerlo nel file `.vimrc` , come da codice sottostante:
```vim
" PLUGINS ---------------------------------------------------------------- {{{
" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'
"
" All of your Plugins must be added before the following line

```
Una volta salvato il file, digitare `:PluginInstall` .
Quando l'installazione è completata, è buona norma cancellare la cache del buffer digitando il comando `:bdelete` .
È possibile ricercare plugin nel Web oppure tramite il comando `:PluginSearch` . Per aggiornare l'elenco locale dei plugin dal sito vimscripts digitare:
`:PluginSearch!`
