Thanks a lot for taking the time to make those changes @purcell most appreciated.

No problem. Please also test the changes out and let me know if they don't work. In the meantime, I've merged the recipe, so packages will start building on MELPA in the next few hours.

Okay thats fantastic, the changes seemed fine i ran it against a random file with no drone.yml in the path.

I also ran it against this package https://github.com/olymk2/emacs-docker-compose with drone and it ran my ert tests just fine, you can expect this plugin in the future but i am still working on it :)

Thanks again for merging the recipe.
