abyss - Postprocess Hexrays Decompiler Output

Installation

Copy abyss.py and abyss_filters to IDA plugins directory

Usage

Right-click within a decompiler view, pick a filter from the abyss context menu.

Per-filter default settings can be changed by editing the config file: "%APPDATA%/Hex-Rays/IDA Pro/plugins/abyss.cfg"

Disclaimer

Experimental/WIP code, use at your own risk :)

Developers

Create a fresh Python module within "abyss_filters", make sure to inherit from the abyss_filter_t class (see abyss.py).

Re-running the plugin from the plugins menu or by pressing the Ctrl-Alt-R keycombo reloads all filters dynamically. This allows for development of filters without having to restart IDA.

Example filters (incomplete list)

lvars_alias.py (assign variables names depending on context)

signed_ops.py (identify signed operators)

lvars_info.py (append additional info to variable names)

func_colorizer.py (colorize function names)
