Capistrano - find current deployed version

Question

Using Capistrano 3.4, is there a command to find the currently deployed version (branch and tag/revision)?

In the deployed root directory there is a file revisions.log. I could create a custom command to parse it, but especially in the case of a rollback, it's not very easy to parse:

Branch master (at 21) deployed as release 20151207160059 by Marco Branch master (at 22) deployed as release 20151207180000 by Marco Marco rolled back to release 20151207160059

In the release folder there is a file called REVISION which contains the VCS revision identifier that was deployed. You can simply cat that to get the revision.

Following on your initial thoughts, get the current revision (via https://stackoverflow.com/a/34156436/2832282) and use the revision.log file to find the matching branch name

revision_string = Rails.root.join('..', '..', 'revisions.log').readlines.detect { |rev| rev.includes?(revision_from_revision_file) }

"Branch production (at 6d68c9415e4d89a6c3119d68a164e50274a2e790) deployed as release 20190301085412 by Cyril"

and then

revision = revision_string.match(
  /^Branch (?<branch>.+) \(at (?<hash>\w+)\) deployed as release (?<release>\w+)/
)
revision['branch'] # => 'production'
