From @gr2m in #54 (comment):
I think we should use dashes for our arguments, it seems to be the convention for actions/* actions, e.g. see https://github.com/actions/checkout/
Notably, changing the input names affects the translated environment variable names1:
- An input named
my_var is translated to INPUTS_MY_VAR.
- An input named
my-var is translated to INPUTS_MY-VAR.
So, we may want a plan for backwards-compatibility, or we may want to ship this in a major version bump.
