rz-ghidra
This is an integration of the Ghidra decompiler and Sleigh Disassembler for rizin. It is solely based on the decompiler part of Ghidra, which is written entirely in C++, so Ghidra itself is not required at all and the plugin can be built self-contained. This project was presented, initially for radare2, at r2con 2019 as part of the Cutter talk: https://youtu.be/eHtMiezr7l8?t=950
Installing
An rz-pm package is available that can easily be installed like:
rz-pm -i rz-ghidra
This package only installs the rizin part. To use rz-ghidra from cutter, either use a provided pre-built release starting with Cutter 1.9, which bundles rz-ghidra, or follow the build instructions below.
Usage
Usage: pdg # Native Ghidra decompiler plugin
| pdg # Decompile current function with the Ghidra decompiler
| pdgd # Dump the debug XML Dump
| pdgx # Dump the XML of the current decompiled function
| pdgj # Dump the current decompiled function as JSON
| pdgo # Decompile current function side by side with offsets
| pdgs # Display loaded Sleigh Languages
| pdg* # Decompiled code is returned to rizin as comment
The following config vars (for the e
command) can be used to adjust rz-ghidra's behavior:
ghidra.cmt.cpp: C++ comment style
ghidra.cmt.indent: Comment indent
ghidra.indent: Indent increment
ghidra.lang: Custom Sleigh ID to override auto-detection (e.g. x86:LE:32:default)
ghidra.linelen: Max line length
ghidra.nl.brace: Newline before opening '{'
ghidra.nl.else: Newline before else
ghidra.sleighhome: SLEIGHHOME
Here, ghidra.sleighhome
must point to a directory containing the *.sla
, *.lspec
, ... files for
the architectures that should supported by the decompiler. This is however set up automatically when using
the rz-pm package or installing as shown below.
Building
First, make sure the submodule contained within this repository is fetched and up to date:
git submodule init
git submodule update
Then, the rizin plugin can be built and installed as follows:
mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=~/.local ..
make
make install
Here, set the CMAKE_INSTALL_PREFIX
to a location where rizin can load the plugin from.
The install step is necessary for the plugin to work because it includes installing the necessary Sleigh files.
To also build the Cutter plugin, pass -DBUILD_CUTTER_PLUGIN=ON -DCUTTER_SOURCE_DIR=/path/to/cutter/source
to cmake, for example like this:
/my/path> git clone https://github.com/rizinorg/cutter
/my/path> # build Cutter, clone rz-ghidra, etc.
...
/my/path/rz-ghidra> mkdir build && cd build
/my/path/rz-ghidra/build> cmake -DBUILD_CUTTER_PLUGIN=ON -DCUTTER_SOURCE_DIR=/my/path/cutter -DCMAKE_INSTALL_PREFIX=~/.local ..
/my/path/rz-ghidra/build> make && make install
