json-mode — a JSON editing mode

Do not use this project, I’ve abandoned it.

This is a simple JSON editing mode for Emacs.

Features

Folding of Objects and Arrays (C-c C-f to toggle next one, C-c C-u to unfold everything)
Pretty printing files (C-c C-p) (by default when file is opened as well, json-mode-pretty-print-on-open can be set to nil to disable this)
Minification (C-c C-m)
Idle time validation with result displayed on mode line
Validation (C-c C-v)
Get a path to value at point (C-c C-l) in following formats
- JavaScript notation (default)
- bracket notation
- JSON pointer (RFC 6091)

The easiest way to install this mode is to simply put it somewhere in load-path and add

(require 'json-mode)

to your init file.

Files with .json extension will be opened with this mode by default.

This mode has autoload comments, so it should work nicely with lazy loading setups.
