Recently I needed to work with some .json files and notice vim didn’t know how to highlight them. A little baffled I turned to google and discovered json.vim. Installed it, setup the autocommand to reconize .json files as json and was set.
But being stingy about what plugins I load, it dawned on me – vim supports JavaScript, why not just use that for highlighting my json files? doing so was stupid-easy. Just add this line to your .vimrc:
autocmd BufNewFile,BufRead *.json set ft=javascript
Done and done. Got good-enough hihglighting and only added one line of vimscript.
