[BUG] tool.flit.scripts is not extracted as entry_points

[BastianZim]

Describe the bug
A clear and concise description of what the bug is.

This is not 100% confirmed but currently the assumption is that [tool.flit.scripts] in a pyproject.toml file is the same as entry_points. This is not extracted.

To Reproduce
Steps to reproduce the behavior:

1. Run Grayskull on package using pyproject.toml.
2. No entry_points are created.

Expected behavior
A clear and concise description of what you expected to happen.

entry_points are extracted correctly.

Outputs
If applicable, add the output to help explain your problem.

Can be tried with yaqc-qtpy.

Sample package that has the new scripts: https://gitlab.com/yaq/yaqc-qtpy/-/blob/main/pyproject.toml#L33

Maybe now that PEP 517 metadata is supported (and starting to be used by more than just flit) we can start looking at that as the intermediate representation?

https://flit.pypa.io/en/latest/pyproject_toml.html#scripts-section

[project.scripts]
flit = "flit:main"

at that point, supporting a legacy "pun" for the name wouldn't be that hard.

[BastianZim]

Yeah but we need to figure out what exactly the equivalent is because flit also has https://flit.pypa.io/en/latest/pyproject_toml.html#entry-points-sections

Maybe https://flit.pypa.io/en/latest/pyproject_toml.html#scripts-section is scripts from setup.py? In that case it can't be noarch.

[bollwyvl]

I was surprised too, but I think it's a convenience: further down it says you _can't_ have console_scripts and gui_scripts in the entry points table

[BastianZim]

Oh yeah – missed that. Would make the most sense then, agreed.

[dholth]

You could build the wheel or otherwise generate the metadata, and parse scripts out of entry_points.txt

[marcelotrevisani]

Should we close this? or is it still a problem? I am a bit confused here, sorry 😄

[BastianZim]

I think it's still a problem.

In short: Pyproject.toml flit uses [tool.flit.scripts] for entry_points.

This example: https://gitlab.com/yaq/yaqc-qtpy/-/blob/main/pyproject.toml#L42 is not converted into an entry_points but it should.

The confusion above came because I wasn't 100% sure if pyproject.toml[tool.flit.scripts] are the same as entry_points but I think they are.

[dholth]

You could have it do the build and take the entry points out of dist-info.

[marcelotrevisani]

You could have it do the build and take the entry points out of dist-info.

the only problem is that, I would prefer to avoid in creating the whole build, because grayskull just start the build and stop it after it gets all the metadata, that is for setup.py and related. For pyproject.toml I am pretty much parsing the toml file as it is faster and simple to do.
