A dumb way to prettify JSON on the command line.

README.markdown

pjson

Prettifies JSON on the command line.

Installation

Copy into anywhere on $PATH and chmod +x the file. Remove the .rb if you like.

Usage

Prettify a file:

$ pjson minified.json

Works with multiple files, thanks to the magic of ARGF.

$ pjson *.json

Plays nice with pipes:

$ pjson minified.json | less

Plays nice with curl, etc.:

$ curl http://example.org/users.json | pjson

pjson.rb

#!/usr/bin/env ruby

require 'json'

begin
  puts JSON.pretty_generate JSON.load(ARGF)
rescue JSON::ParserError => error
  # Clean up error messages like: 123: unexpected token at '...'
  puts error.message
    .sub(/\A\d+: unexpected token at '/, '')
    .sub(/'\Z/, '')
  warn "--- Not parseable JSON."
  exit(1)
rescue Errno::EPIPE
  exit(74)
end
