setMin / setMax no longer working in 1.4.0

[briankendall]

The setMin and setMax methods on pymel.core.general.Attribute no longer appear to work in PyMEL 1.4.0. When calling them they silently fail, and don't actually set a minimum or maximum. Example:

import pymel.core as pm
node = pm.spaceLocator()
node.addAttr("testAttr", at="double", keyable=True)
node.testAttr.setMin(0.0)
node.testAttr.setMax(1.0)
print(node.testAttr.getMin(), node.testAttr.getMax())

In PyMEL 1.1.0 / Maya 2020, this correctly prints (0.0, 1.0).

In PyMEL 1.4.0, it incorrectly prints None None.

I'm not sure at which point exactly this bug was introduced.

Find the pymel/core/general.py

There are two extra overloads after the setRange implementation.

e.g.,

  @overload
    def setRange(self, range):
        # type: (Tuple[Optional[float], Optional[float]]) -> None
        pass

    @overload
    def setRange(self, newMin, newMax):
        # type: (Optional[float], Optional[float]) -> None
        pass

    def setRange(self, *args):
        # type: (*Union[Optional[float], Tuple[Optional[float], Optional[float]]]) -> None
        """provide a min and max value as a two-element tuple or list, or as two arguments to the
        method. To remove a limit, provide a None value.  for example:

            >>> from pymel.core import *
            >>> s = polyCube()[0]
            >>> s.addAttr( 'new' )
            >>> s.new.setRange( -2, None ) #sets just the min to -2 and removes the max limit
            >>> s.new.setMax( 3 ) # sets just the max value and leaves the min at its previous default
            >>> s.new.getRange()
            [-2.0, 3.0]

        """

        self._setRange('hard', *args)

    @overload
    def setRange(self, range):
        # type: (Tuple[Optional[float], Optional[float]]) -> None
        pass

    @overload
    def setRange(self, newMin, newMax):
        # type: (Optional[float], Optional[float]) -> None
        pass

Removing them should fix this problem.

The fix for this is included in the latest release of pymel. Installing 1.5.0 from pypi should fix your problem. 👍
