While I was playing around with CouchDB and cURL I pretty quickly missed a feature to indent the json output string. So after looking around in the Internet for a simple solution I hit simplejson which provides methods to indent a json string.
Get the script
With simplejson I’ve created the following python script:
#!/usr/bin/env python import sys import simplejson import string content = string.join(sys.stdin.readlines()) json = simplejson.loads(content) print simplejson.dumps(json, sort_keys=True, indent=2)
What needs to be installed
To be able to run the script simplejson needs to be installed. On a debian based system you can easily run following command to assure simplejson is installed:
sudo apt-get install python-simplejson
How to use it
Let’s store the script to jsonindent.py in a executable path directory such as $HOME/bin (run echo $PATH to get more possible directories). To indent a json script returned for instance from a CouchDB you can easily use following command:
curl -sX GET http://127.0.0.1:5984/example/hello-world | jsonindent.py
The output will look like this:
"body": "Well hello and welcome to my new blog...",
"date": "2009/01/15 15:52:20",
"title": "Hello World"
Looks pretty neat, doesn’t it ?
