copier: init at 7.0.1

Motivation for this change

Thought I would try my hand at packaging this, someone mentioned they had great difficulty doing so, and I would agree.

The upstream repo contains a couple of tests.

Tests would be available if the source from GitHub is used.

[SuperSandro2000]

That should be part of setuptools-scm actually.

Unfortunately it seems the main functionality of this package is broken atm, in a similar way as to when I made my attempt.

${copier} --help correctly prints what's expected, however, beyond this help message, little works as it ought to:

If you set up a simple template like so:

mkdir my-template
cd my-template
echo "filename:
  type: str
  help: What's the name of the file?
  default: myDefaultName
  " > copier.yml
echo "Hi, I'm [[ filename ]]" > '[[ filename ]].txt.tmpl'

and then run copier my-template cop-test

you should get a prompt requesting a value for filename, supposing we entered "working", in cop-test there should then be one file named working.txt with the contents "Hi, I'm working".

When this package is used, versus the copier installed via pipx, a similar (but not identical) prompt appears, and seems to accept a value, however you will find that only the raw file is copied over, with no substitutions done. So in cop-test there will be a file named '[[ filename ]].txt.tmpl' with the contents "Hi, I'm [[ filename ]]".

This seems to be intended behavior https://github.com/copier-org/copier/blob/master/CHANGELOG.md#changed

We use Jinja 2 defaults now. {{ }} instead of [[ ]] and similar.

One thing to note is that I'm packaging off their master since it's more coherent with the rest of python packages. Breaking changes won't be reflected.

oh no... that means i might have had it in an actual working state before... my apologies, thank you, I at least for sure didn't properly package any of the dependencies for nix as you did here

EDIT: After more testing, they changed the default template extension too from .tmpl to .jinja! I didn't even see that in the changelog!

I will name one of my children after you

Would be great if this could be merged! Thanks

FWIW Copier 6 was recently released. You'd probably prefer to package that?
