Function _pascal_resolve_class

graphify/extract.py:13029–13054

Resolve a Pascal class/interface name to the node ID of its defining file's class node. Pascal convention: TFooBar is defined in FooBar.pas, IFooBar in FooBar.pas. Strips the leading T/I prefix, finds the file, and returns _make_id(_file_stem(found_file), class_name). Returns None
