 1 | # vim-cfmt
 2 | 
 3 | A vim plugin using 
 4 | [gnu indent](https://www.gnu.org/software/indent/manual/indent.html) 
 5 | to auto format C source code.
 6 | 
 7 | You will need to install `indent` on your system to use this plugin.
 8 | If you are on a debian based system you can use apt to install it.
 9 | ```bash
10 | apt-get install indent
11 | ```
12 | 
13 | Install using Pathogen or Vundle then set this in your `vimrc`:
14 | ```vimrc
15 | autocmd BufWritePre *.c,*.h Cfmt
16 | ```
17 | 
18 | You can configure the style of formating by using the `g:cfmt_style` 
19 | variable.
20 | 
21 | ```vimrc
22 | let g:cfmt_style = '-linux'
23 | let g:cfmt_style = '-kr'
24 | let g:cfmt_style = '-gnu'
25 | ```
