target 'rules_python_wheel_entry_point_hjson' not declared in package

[kriswuollett]

🐞 bug report

The entry_point for package hjson does not work with v0.6.0.

Is entry_point not fully available for use yet? I don't see any mention of it on the top level README.md.

Affected Rule

entry_point method

Is this a regression?

Not sure. First time I've tried using this feature of rules_python. Perhaps this package is a different case of an invalid entry points config?

Description

The rules_python_wheel_entry_point_hjson not generated for requirement hjson==3.0.2:

🔬 Minimal Reproduction

[UebelAndre]

This issue is caused by the hjson executable coming from setup.py, and not being a console script (entry point) defined in the wheel.

https://github.com/hjson/hjson-py/blob/master/setup.py#L75

This could potentially be "fixed" (I'd call this more of a feature-request fulfillment) by https://github.com/bazelbuild/rules_python/pull/575

This issue has been automatically marked as stale because it has not had any activity for 180 days. It will be closed if no further activity occurs in 30 days. Collaborators can add an assignee to keep this open indefinitely. Thanks for your contributions to rules_python!

[UebelAndre]

Cc @groodt This would be fixed by having support for setup.py scripts. Perhaps this can be collapsed or covered to a ticket tracking that specific feature?

[groodt]

Agreed. I think I'll create an "umbrella" tracking issue for "legacy scripts support".

fwiw, it seems that perhaps hsjon will switch to entrypoints (or at least are being encouraged by conda to do so) https://github.com/hjson/hjson-py/pull/29

[groodt]

This particular issue with hjson is fixed in hjson==3.1.0.

Tested against the minimal reproduction and it works.
