# HRAST

> HRAST is an IDAPython proof of concept for matching and rewriting the Hex-Rays ctree. Load HRAST.py, put pattern tuples in read_patterns.py, and call reLOAD() so the decompiler window picks them up. unLOAD() turns the changes off. The included patterns rename globals and structure fields and replace an inlined strlen on a global. ast_helper.py builds ctree items. The reviewed page points the ctree verifier at IDA 7.1 or newer.
