Getting elixir app version from command line
In some cases you need to know the version that is defined in your applications mixfile from the command line, maybe for an automated deployment process. No matter the case here is how you do it:
create a mix task and place it at
defmodule Mix.Tasks.App.Version do use Mix.Task def run(_) do IO.puts Mix.Project.config[:version] end end
Now you can easily get the current version by running
mix app.version in your terminal.
If you don’t like the idea of adding a mix task for this or you cannot run mix in the environment you’re in I found this little command helpful:
cat mix.exs | grep version | sed -e 's/.*version: "\(.*\)",/\1/'
