There was a circular dependency between platform.py and preprocessor.py:
PlatformstoresMacroandMacroFunctionobjects; andMacroExpanderrequires aPlatform.Breaking this dependency enables
Platformarguments in preprocessor.py to be decorated with the correct type-hints. This code structure is also a better reflection of howPlatformis used by the preprocessor.Related issues
Proposed changes
Platformdefinition from platform.py to preprocessor.pyplatform.Platformto usepreprocessor.Platforminstead.Reviewing the code, it is clear that a
Platformdoesn't really represent a "platform" in the sense we mean it elsewhere. It's really something like a "preprocessor state", and we construct a differentPlatformfor each file in a codebase. As a follow-up to this PR I intend to renamePlatformand tidy it up, but I wanted to make sure simply moving the class didn't break anything before going further.
