Setting variables in a python script doesn't work

[villi]

I'm new to making workflows using python scripts. I am trying to set som variables inside a python file that runs through the the "run scripts" block. However I can't get it to work, and I don't know what I'm doing wrong.

import sys
import re
import json

query = sys.argv[1]

data = {
    "alfredworkflow": {
        "arg": "",
        "config": {
        },
        "variables": {
            "a": "test"
        }
    }
}

json.dump(data, sys.stdout)

 

The python file outputs isn't able to parse the JSON, and instead just outputs it as a string: "{"alfredworkflow": {"arg": "", "config": {}, "variables": {"a": "test"}}}". And when I use {var:a} in a notification block, it's empty.

' to Post Notification

that last input part doesn't seem valid JSON.... where is input supposed to be?

Welcome @villi,

 

You have unnecessary code your snippet. Unless input is supposed to come into play. But if it is, as @giovanni noted it’s not clear what it’s supposed to refer to.

 

With the given information, this should work:

 

import sys
import json

data = {
  "alfredworkflow": {
    "variables": { "a": "test" }
  }
}

json.dump(data, sys.stdout)

@vitor Thanks!

Don't know what the difference between your code and mine was, but it somehow works now!

Legends!

 

Thanks so much for posting this here. I've been looking for docs on the JSON object for the workflow for ages and no amount of Googling yielded anything until I found this solution which worked a treat. It's incredibly useful for validating and calculating variables which can be used later in the workflow. Thanks again.

It’s documented on the help pages.

@Sam Michel As a heads-up alongside Vítor's response (for you and anyone else who comes across this thread), every workflow object has a question mark icon in the configuration, which will take you to the documentation for that specific object  This is the best starting point for insight on configuring that particular workflow object!

Thanks @Vero and @vitor
