@lkysow could this get merged and released?

[lkysow]

Looks great, thanks for updating the docs too! Just a small suggestion.

[llamahunter]

Sure. I am just exposing the existing variable that's already there in atlantis, as I don't want to try to parse it out of the full path variable by searching for the workspace name or something.

[lkysow]

Oh for sure, we should have had this to start.

[llamahunter]

so... I know you just did a release, but when do you think this might go out?

[lkysow]

Probably in the next week or two.
