parse json using yaql

[BrGitHub11]

I created a workflow and one of my bash commands returns json. E.g.
{ "g": { "a": "b", "c": "d" }, "e": "f" }
I store the output in a variable:
publish: myvar=<% result().stdout %>
Now I want to access one of the fields of my json. So something like:
my_a=<% ctx(myvar)XXXX %>
I'm not able to figure how to do this. Any help is appreciated.

You should be able to access with something like <% ctx(myvar).fieldname %> if your json you stored was a dictionary with key "fieldname". But the output might be a json string rather than json - e.g. take a look at the result.stdout.

so you might need to use the Jinja from_json_string function - e.g. https://docs.stackstorm.com/reference/jinja.html#from-json-string if you need to convert from a string to a json object.
