YAMS Ghidra External Plugin (Experimental)

This example provides an External (Python) plugin for YAMS that uses PyGhidra to analyze binaries. It speaks newline‑delimited JSON‑RPC over stdio using the SDK in external/yams-sdk.

Prerequisites

• Ghidra 12.0+ installed
• Python 3.8+
• PyGhidra: pip install pyghidra (or from your Ghidra install as per PyGhidra README)
• Set GHIDRA_INSTALL_DIR or provide ghidra_install in the plugin init config

Location and install

• This plugin now lives under plugins/yams-ghidra-plugin.
• Install is opt-in: build with -DYAMS_INSTALL_GHIDRA_PLUGIN=ON to install into ${CMAKE_INSTALL_LIBDIR}/yams/plugins/yams-ghidra-plugin.

Quick run (standalone)

# From repo root
export PYTHONPATH="$PWD/external/yams-sdk/python:$PYTHONPATH"
python examples/plugins/yams-ghidra-plugin/plugin.py

# In another shell: send handshake + init + a test call
printf '%s
' '{"id":1,"method":"handshake.manifest"}' | python examples/plugins/yams-ghidra-plugin/plugin.py

JSON‑RPC methods

• handshake.manifest → returns {name, version, interfaces: ["ghidra_analysis_v1"]}
• plugin.init → input {ghidra_install?: "/path/to/ghidra", project_dir?: "/tmp/ghidra", project_name?: "YamsGhidra"}
• plugin.health → {status:"ok"}
• ghidra.analyze → input {source:{type:"path", path:"/path/to/bin"}}, output {arch, functions:[{name, addr}], count}
• ghidra.decompile_function → stub (to be implemented)

Notes

• This example uses PyGhidra’s high‑level helpers and may be refined to use ProgramLoader and DecompInterface directly.
• For end‑to‑end with YAMS, integrate with the future ExternalPluginHost.
