Helper functions for comparing `lsst.pex.config.Config` instancess. Theses function should be use for any comparison in a `lsst.pex.Config.compare` or `lsst.pex.config.Field._compare` implementation, as they take care of writing messages as well as floating-point comparisons and shortcuts.

Compare two `lsst.pex.config.Config` instances for equality. This function is a helper for `lsst.pex.config.Config.compare`. Parameters ---------- name : `str` Name to use when reporting differences, typically created by `getComparisonName`. c1 : `lsst.pex.config.Config` Left-hand side config to compare. c2 : `lsst.pex.config.Config` Right-hand side config to compare. shortcut : `bool`, optional If `True`, return as soon as an inequality is found. Default is `True`. rtol : `float`, optional Relative tolerance for floating point comparisons. atol : `float`, optional Absolute tolerance for floating point comparisons. output : callable, optional A callable that takes a string, used (possibly repeatedly) to report inequalities. For example: `print`. Returns ------- areEqual : `bool` `True` when the two `lsst.pex.config.Config` instances are equal. `False` if there is an inequality. See Also -------- lsst.pex.config.compareScalars Notes ----- Floating point comparisons are performed by `numpy.allclose`. If ``c1`` or ``c2`` contain `~lsst.pex.config.RegistryField` or `~lsst.pex.config.ConfigChoiceField` instances, *unselected* `~lsst.pex.config.Config` instances will not be compared.

Compare two scalar values for equality. This function is a helper for `lsst.pex.config.Config.compare`. Parameters ---------- name : `str` Name to use when reporting differences, typically created by `getComparisonName`. v1 : object Left-hand side value to compare. v2 : object Right-hand side value to compare. output : callable or `None` A callable that takes a string, used (possibly repeatedly) to report inequalities (for example, `print`). Set to `None` to disable output. rtol : `float`, optional Relative tolerance for floating point comparisons. atol : `float`, optional Absolute tolerance for floating point comparisons. dtype : class, optional Data type of values for comparison. May be `None` if values are not floating-point. Returns ------- areEqual : `bool` `True` if the values are equal, `False` if they are not. See Also -------- lsst.pex.config.compareConfigs Notes ----- Floating point comparisons are performed by `numpy.allclose`.

lsst.pex.config.comparison.getComparisonName | ( | name1, | |
name2 ) |
Create a comparison name that is used for printed output of comparisons. Parameters ---------- name1 : `str` Name of the first configuration. name2 : `str` Name of the second configuration. Returns ------- name : `str` When ``name1`` and ``name2`` are equal, the returned name is simply one of the names. When they are different the returned name is formatted as ``"{name1} / {name2}"``.
