Configuration for better JSON editing in Vim

json-vim-config.md

Install jsonlint to act as syntastic json checker:

$ npm install jsonlint -g

Tell syntatastic about it:

" in your ~/.vimrc
let g:syntastic_json_checkers = ['jsonlint']

Get some syntax highlighting (also covers ftdetect to set json filetype)

" in your ~/.vimrc
Bundle 'elzr/vim-json'

" Disable fancy concealing of attribute quotes.
let g:vim_json_syntax_conceal = 0

Pretty Print JSON

I used to work with large JSON objects and pretty printing within vim was nice.

Install jsontool to make working with JSON easier:

npm install jsontool -g

Add this awesome vim function to your vimrc!

function! PrettyJSON()
  :%!json
  set filetype=json
endfun
:command! PrettyJSON :call PrettyJSON()

The vim-json plugin just updated with a fix for the Undefined variable: g:vim_json_warnings. elzr/vim-json#32
