This is an IDA Pro Python plugin to make Hex-Rays Decompiler output bit more attractive. HRDEV plugin retrieves standard decompiler output, parses it with Python Clang bindings, does some magic, and puts back.

The only requirement is Clang Python binding. See https://pypi.python.org/pypi/clang. Clang binding is required to parse decompiler output and produce plugin output.

First install Clang Python binding if you dont have it, then just paste plugin into "plugins/" IDA folder and plugin will be available on startup.

Load plugin, then press "Alt + ," and listing will appear. Currently this is an alternative only to a standard "Alt + F5" (function decompilation), listing for complete files is currently not supported.

As this plugin is written in Python, parsing huge file may be time consuming, so it probably makes no sense to support complete file parsing.

HRDEV plugin has other key shortcuts:

• Ctr+S - will save current document
• Ctr+F - will pop up find-replace modal dialog

HRDEV plugin comes with several themes for syntax highlighting, however, you can edit them or add own. To add your own, simply paste file with certain theme name to folder "data/themes" and edit your file. The name of the file is the name of the theme.

For various editor options please take a look at "data/config.ini" and configuration files in "data/themes/*.ini". Files contain comments, so it should not be difficult to understand how to configure editor.

You can toggle line highlight on-off by clicking twice on line number bar.

Please note that Hex-Rays decompiler tabulation width has to match with plugin tabulation width setting, otherwise you get ugly indentation.

Plugin may print that there were some Clang parsing errors, but normally that is not of a big concern, usually you can ignore them.

Plugin saves all decompiled files to the "hrdev_cache/MODULE_NAME/*" temporary folder. It is done so you can save changes made to file. Next time when Alt+, is pressed, plugin will lookup for file in cache. If you want to discard changes made, simply delete file in "hrdev_cache/MODULE_NAME/*" folder.

This is still beta-release, so I am pretty sure you will find some bugs. Don't hesitate to report them.

Plugin was tested on Windows only, however, I believe that there should be no problems on other platforms.

This is how usually output looks like:

This is how output looks by plugin:

• toggle casts
• add menu like in original output

Work is still ongoing, and please, make feature requests!
