Which Alfred versions support the alfred_workflow_data, etc. environment variables?

[caleb531]

The Alfred documentation lists a number of Alfred-specific environment variables I can use in my workflow scripts. In my case, I'm using alfred_workflow_bundleid and alfred_workflow_data in my workflow.

 

For example, here's some Python code from my workflow that uses these environment variables. Certainly, I can expect these variables to exist in Alfred 5, but I'm unsure of Alfred 4 support, so I've added hardcoded fallback values just in case.

 

WORKFLOW_BUNDLE_ID = os.environ.get('alfred_workflow_bundleid', 'com.calebevans.youversionsuggest')
HOME_DIR_PATH = os.path.expanduser('~')
LOCAL_DATA_DIR_PATH = os.environ.get(
    'alfred_workflow_data',
    os.path.join(HOME_DIR_PATH, 'Library', 'Application Support', 'Alfred',
                 'Workflow Data', WORKFLOW_BUNDLE_ID))

 

So how far back are these supported? Are they available in Alfred 4 or 3?

Thank you in advance!

Sidenote: I originally posted this question on Twitter and was directed to ask it here on the forums.

v3 for sure, perhaps even as far back as v2.4

Most of the script environment variables available in Alfred 5 were also available in as far back as Alfred 2.

 

Manually copying out from the Alfred 2 code so I may have missed one or two:

 

alfred_version
alfred_version_build
alfred_theme
alfred_theme_subtext
alfred_theme_background
alfred_preferences
alfred_preferences_localhash
alfred_workflow_uid
alfred_workflow_bundleid
alfred_workflow_cache
alfred_workflow_data
alfred_workflow_name

 

I think you're safe to not need to code in fallbacks
