How to make --data available from a file?

[eyllanesc]

If I have the following configuration file:

copier.yml

key1:
  type: str

key2:
  type: str

I know you can pass the arguments through --data:

copier from to --data key1="foo" --data key2="bar"

But in some cases you want to pass the predefined responses, for example a file:

config.yml

key1: foo
key2: bar

How can I do something like: copier from to ---data-from-file config.yml?

Ooops, the solution is documented in: https://copier.readthedocs.io/en/stable/configuring/#answers_file

How do you achieve this when initially copying a template using an answerfile? It does not appear to be the solution to the problem you describe. The stale pr #485 mentioned by @yajo could be the solution …

#485 is an attempt to implement that, but it seems stale now.
