• Tree Sitter, Pharo Smalltalk version

Extension Messages

This project implements a few extension messages in order to handle things as they would be in Python. Translated code uses these extensions in certain situations.

• toPythonBoolean converts a value to a boolean based on Python truthiness. Related messages like pythonOr: do boolean operations based on truthiness.
• zwAt: and related messages allows indexing arrays according to Python conventions (initial index is 0, negative indices access elements at the end).
• switch implements a switch/cond statement, used for translating if/elif statements. ifTrue: and ifTrue:ifFalse: are used for if statements without elifs.
