A Vim plugin for the Rego language that includes support for syntax highlighting.

Vundle Installation

In your .vimrc file add the line Plugin 'tsandall/vim-rego', like so:

call vundle#begin()
Plugin 'VundleVim/Vundle.vim'
" ... other plugins here ...

Plugin 'tsandall/vim-rego'

" All of your Plugins must be added before the following line
call vundle#end()            " required

Formatting

vim-autoformat

You can configure Vim to automatically format your Rego policies using opa fmt. Install the vim-autoformat plugin then put this in your .vimrc:

let g:formatdef_rego = '"opa fmt"'
let g:formatters_rego = ['rego']
let g:autoformat_autoindent = 0
let g:autoformat_retab = 0
au BufWritePre *.rego Autoformat

If you want to see parse errors that occurred during formatting put this in your .vimrc as well:

let g:autoformat_verbosemode = 1

Neoformat

If you are using neoformat plugin, then put this in your .vimrc:

let g:neoformat_rego_opa = {
      \ 'exe': 'opa',
      \ 'args': ['fmt'],
      \ 'stdin': 1,
      \ }

let g:neoformat_enabled_rego = ['opa']

Now, :Neoformat command will use opa to format rego files.

To make Neoformat auto-format on save, put this in your .vimrc:

augroup fmt
  autocmd!
  autocmd BufWritePre * undojoin | Neoformat
augroup END
