modelx v0.7.0 (24 May 2020)¶
This release introduces some new features and fixes bugs around updating objects and values upon model changes.
Enhancements¶
Introduction of UserSpace.formula
setter and deleter
The UserSpace.formula
property now supports assignment
and deletion operations, such as:
>>> Space.formula = lambda x, y: None
>>> del Space.formula
When the Formula of a UserSpace is reassigned or deleted, existing child ItemSpaces are deleted.
Introduction of UserSpace.parameters
setter
The UserSpace.parameters
property now supports assignment
operation, such as:
>>> Space.parameters = ('x', 'y=0')
The assignment to UserSpace.parameters
is a syntactic sugar
and the code above is equivalent to:
>>> Space.set_formula(lambda x, y=0: None)
Other enhancements
itemspaces
to return a mapping of arguments to childItemSpace
object.clear_all()
andclear_at()
methods onUserSpace
.
Backward Incompatible Changes¶
get_object()
now returnsNameError
when the name is not found.ItemProxy
renamed toElement
.Only tuples are interpreted as multiple indexes in subscription expression.
Bug Fixes¶
References not being updated for reassigned Formulas.
Sub spaces directly under Model not being updated after its bases’ deletion.
Dependents values not being cleared at Cells’ deletion.
