GN vim syntax plugin

Installation with a plugin manager

You can use modern plugin managers to download the GN repo and manage the vim plugin:

Example config for vim-plug:

Plug 'https://gn.googlesource.com/gn', { 'rtp': 'misc/vim' }
1

Or, for Vundle users:

Plugin 'https://gn.googlesource.com/gn', { 'rtp': 'misc/vim' }
1

Manual installation

If you don't use a plugin manager or would prefer to manage the GN repo yourself, you can add this explicitly to rtp in your .vimrc:

set runtimepath+=/path/to/gn/misc/vim
" ...
filetype plugin indent on " or a similar command to turn on filetypes in vim

Formatting GN files

vim-codefmt supports the GN filetype natively. Add the following to your .vimrc:

" Install vim-codefmt and its dependencies
Plug 'google/vim-maktaba'
Plug 'google/vim-codefmt'

" Install this plugin:
Plug 'https://gn.googlesource.com/gn', { 'rtp': 'misc/vim' }

" Optional: configure vim-codefmt to autoformat upon saving the buffer.
augroup CodeFmt
  autocmd!
  autocmd FileType gn AutoFormatBuffer gn
  " Other file types...
augroup END

This will autoformat your files every time you save. If you prefer not to format files upon saving, vim-codefmt can format the buffer by calling :FormatCode.

Included format integration

If you cannot include vim-codefmt, you can use the limited gn format integration included in this plugin. Add the following to your .vimrc:

" Replace <F1> with whichever hotkey you prefer:
nnoremap <silent> <F1> :pyxf <path-to-this-plugin>/gn-format.py<CR>
