Module: Code ./src/peak/util/Code.py

Bytecode inspection and patching - like a simpler (faster!) bytecodehacks

Similar to the Python bytecodehacks package, this module supplies Code and Function objects which are mutable versions of the real things. The main difference between this module and bytecodehacks is that this module values speed above nearly all other considerations, and thus only offers in-place bytecode patching, and eschews most of the higher-level facilities offered by bytecodehacks. But it's plenty enough for what PEAK needs.

The module makes available many useful values; you can get any opcode as a constant from it by explicit import, such as:

        from peak.util.Code import LOAD_NAME, STORE_NAME

There's also an opcode array that you can import that maps opcode names to values.
