external data source with a ruby script

[Vikas Kumar]

Hey All,

This link shows how to use vars passed by external data source in a bash script.

#!/bin/bash
eval "$(jq -r '@sh "FOO=\(.foo) BAZ=\(.baz)"')"

What would be the ruby equivalent of this?

Cheers,

Vikas

All that bash is doing is reading in the query values into variables, though since bash doesn't know JSON natively, it's convoluted.

In Ruby it would be more straightforward:

    #!/usr/bin/env ruby

    require 'json'

    data = JSON.parse(STDIN.read)

Then if the vars passed were `foo` and `bar`, they would be available to ruby as `data['foo']` and `data['bar']`.

Perfect !!

Thanks a ton David. I am not very well versed with Ruby, but growing steadily :)

Cheers,
