AttributeError: 'function' object has no attribute 'run_cli' about robotframework HOT 6 OPEN

This is related to #4129. The buildout generates the following code for the entry point:

import robot.run

if __name__ == '__main__':
    sys.exit(robot.run.run_cli())

Then the above error occurs when running the script.

I don't think changing the way the entry point is written would solve the problem. I think what would solve it would be to eliminate the confusion of "run" in both types of import. Of course the buildout could be wrong too, but that doesn't invalidate this issue here.

but could you not switch the entry points to use the root module directly?

humm @choeger' suggestion works. If the entry point is changed to:

'robot = robot:run_cli'

The script generated by buildout would be:

import robot

if __name__ == '__main__':
    sys.exit(robot.run_cli())

and it would work.

This is due to the robot root module having both a run sub module and a run function. This isn't great design but there are historical reasons for it.

The run module exists to allow running Robot like python -m robot.run. That's not too relevant nowadays when python -m robot works, but that wasn't possible back in Python 2.6 days.

The run function is there just to have a convenient API for running Robot programmatically. I believe it was added after the run module was introduced and could have been named differently, but run felt (and feels) like a good name for this purpose and the function and the module having the same name didn't seem to cause problems.

To resolve the issue, we needed to rename either the module or the function. As I wrote otherwise, python -m robot.run usage isn't that important anymore, so I believe renaming the module would be a better idea. That would, however, be a backwards incompatible change causing issues for anyone possibly still using python -m robot.run or importing anything from the robot.run module. I'm not sure the change worth the problems it would cause.

@pekkaklarck I think it should be renamed because it causes confusion. But if it's going to cause a lot of trouble, could you at least change the entry point to work with buildout?

Do you mean that in our setup.py we should change 'robot = robot.run:run_cli' to 'robot = robot:run_cli'? That sounds fine, but I'm slightly worried about possible side-effects and believe it would be safer to do that in RF 7.1 than in 7.0.1.

Yes. Remembering that the other entrypoints will require the same change.

That sounds fine, but I'm slightly worried about possible side-effects and believe it would be safer to do that in RF 7.1 than in 7.0.1.

The run module will continue to exist. So I don't see a problem with making this change in 7.0.1. I don't see anything breaking. I think it's a safe change to make.

But in any case, changing the module name cannot be lost sight of. Maybe in an 8.0 version?
