Formatting JSON

Here's something you probably had to do at some point. You have some big json blob and you want to format it nicely.

I had done this in vim and honestly, it comes very very easy.  In vim, if you have a buffer (/tmp/foo.json) you want to reformat, and you have jq, the nicest way I've found is something like:

:r !jq %

This is really hard to beat, and I'm not sure you can be much faster in any other thing.

But I live inside emacs, and I when I have this need, until now, I was selecting the region, then `M-| jq .`  The problem is I always forget about m-|, and it's really annoying to type it anyway.

So I was about to create my elisp function that would reformat my json region, and before coding it, I timidly tried M-x json-form..  and yes, of course, json-reformat-region is already there (you can download it from melpa).  Job done.

Btw, if you use evil, you can also use ':r !jq /tmp/foo.json'.  For some reason, % doesn't work as a substitute for the current buffer-file-name, but at that point, I don't care much. :)
