jsl
Slice and dice JSON at the command line.
Installation
gem install jsl
Ideas
- Look at Dir.glob implementation
- regex instead of glob?
- SAX-based parser like https://bitbucket.org/webmat/htmlparser.js
Usage
By default, jsl outputs one value per line. Unless --strict is specified,
it may not be a strict JSON string.
# Note: ohai outputs information about your machine in JSON.
$ gem install ohai
$ ohai | jsl /os
darwin
$ aws ec2 run-instances [...] | jsl InstanceId
i-beef42
Given
