Vh rUdZddlZddlmZiZeeeeeffed<d dZ deddfdZ ded edeefd Z y) a This module provides functionality for caching and looking up fully qualified function and class names from Python source files by line number. It uses Python's tokenize module to parse source files and tracks function/class definitions along with their nesting to build fully qualified names (e.g. 'class.method' or 'module.function'). The results are cached in a two-level dictionary mapping: filename -> (line_number -> fully_qualified_name) Example usage: name = get_funcname("myfile.py", 42) # Returns name of function/class at line 42 clearcache() # Clear the cache if file contents have changed The parsing is done lazily when a file is first accessed. Invalid Python files or IO errors are handled gracefully by returning empty cache entries.
