Expose workflow version as environment variable

Alfred already exposes info such as `alfred_workflow_name`, so it would make sense to also add `alfred_workflow_version` too. This can be useful to for debugging purposes and migration scripts.

Not much of a value proposition to having a version number in Alfred if it isn't available via environment variables, IMO.

 

When Alfred added environment variables, it made it possible to write workflows without parsing info.plist (to figure out data and cache directories, for example).

 

Utilising the Workflow Version set in Alfred means that you have to go back to parsing info.plist again, which is a significant regression in terms of complexity and performance overhead compared to what people are currently doing. Basically, writing workflows like it's 2013.

 

It also means that, no, you can't forget about XML in Alfred 3

Yup, I ended up having to extract it out of the info.plist: https://github.com/sindresorhus/alfy/blob/42c59bc7d53f5d2fcbbfc1d45386bd1d99b2dea9/index.js#L29

This was an oversight and should have made it into v3.0. If you update to the Alfred 3.0.3 pre-release b692, this is now set as script environment variable 'alfred_workflow_version'

 

Cheers,
