feat: Allow copier-templates-extensions as an extra

[henryiii]

This allows pipx users to use this:

pipx install copier[templates-extensions]

Or this:

pipx run copier[templates-extensions] <args>

Instead of this:

pipx install copier
pipx inject copier copier-templates-extensions

I think this was mentioned a while back, but never added.

I'm not very familiar with non-PEP 621 backends (Poetry. Just Poetry.), so hopefully I got the syntax correct. Also not sure if you want a min version here.

LGTM! But the poetry.lock file needs to be updated:

poetry lock --no-update

The current project's supported Python range (>=3.8) is not compatible with some of the required packages Python requirement:
  - copier-templates-extensions requires Python >=3.6.1,<3.10, so it will not be satisfied for Python >=3.10
  - copier-templates-extensions requires Python >=3.6.1,<3.10, so it will not be satisfied for Python >=3.10
  - copier-templates-extensions requires Python >=3.6.2,<3.11, so it will not be satisfied for Python >=3.11

Because no versions of copier-templates-extensions match <0.1.0 || >0.1.0,<0.1.1 || >0.1.1,<0.2.0 || >0.2.0,<0.3.0 || >0.3.0
 and copier-templates-extensions (0.1.0) requires Python >=3.6.1,<3.10, copier-templates-extensions is forbidden.
And because copier-templates-extensions (0.1.1) requires Python >=3.6.1,<3.10, copier-templates-extensions is forbidden.
And because copier-templates-extensions (0.2.0) requires Python >=3.6.2,<3.11
 and copier-templates-extensions (0.3.0) depends on copier (>=6), every version of copier-templates-extensions requires copier (>=6).
So, because copier depends on copier-templates-extensions (*)
 and copier is 0.0.0, version solving failed.

  • Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties

    For copier-templates-extensions, a possible solution would be to set the `python` property to ">=3.8,<3.10"
    For copier-templates-extensions, a possible solution would be to set the `python` property to ">=3.8,<3.10"
    For copier-templates-extensions, a possible solution would be to set the `python` property to ">=3.8,<3.11"

(The stuff about limits is bogus, because older versions used to have Python caps, that's not the correct solution and would result in the wrong solve)

I could probably just change the dummy version number, not sure if there's a better way to fix this with the poetry-dynamic-versioning hack. Edit: I did that, can try something else if someone has a different suggestion.

[sisp]

I assume you installed the poetry-dynamic-versioning plugin, right? If so, it seems that Poetry's dependency resolver does not consider the version computed by the plugin but instead simply uses the version from the metadata. I wonder whether the plugin could be extended to let Poetry use the computed version during dependency resolution. Then, hardcoding a sufficiently high though arbitrary version in our metadata would not be necessary.

I assume you installed the poetry-dynamic-versioning plugin, right?

Ah, no, I was just using my brew-installed poetry, which doesn't support adding plugins. I just unlinked my poetry with brew, then installed poetry with pipx and injected the plugin. That fixed it. Other tools (like PDM or Hatch) usually respect your build-system.requires, but Poetry plugins apparently don't.

Nice! The RTD build is failing because poetry-dynamic-versioning is not installed there. This should be fixed by adding poetry self add "poetry-dynamic-versioning[plugin]" to .readthedocs.yml after Poetry is installed. I'm not sure why the two CI / flake-check ... checks are failing though.

[henryiii]

Okay, fixed readthedocs. On the nix jobs (CI / flake-check), it's still giving:

Run copier --version
/Users/runner/work/_temp/ede4b13e-8f0d-4491-9ff7-7771f5b39c64.sh: line 1: copier: command not found
