* Add draft for Ghidra function import script * feature: Basic PDB analysis [skip ci] This is a draft with a lot of open questions left. Please do not merge * Refactor: Introduce submodules and reload remedy * refactor types and make them Python 3.9 compatible * run black * WIP: save progress * fix types and small type safety violations * fix another Python 3.9 syntax incompatibility * Implement struct imports [skip ci] - This code is still in dire need of refactoring and tests - There are only single-digit issues left, and 2600 functions can be imported - The biggest remaining error is mismatched stacks * Refactor, implement enums, fix lots of bugs * fix Python 3.9 issue * refactor: address review comments Not sure why VS Code suddenly decides to remove some empty spaces, but they don't make sense anyway * add unit tests for new type parsers, fix linter issue * refactor: db access from pdb_extraction.py * Fix stack layout offset error * fix: Undo incorrect reference change * Fix CI issue * Improve READMEs (fix typos, add information) --------- Co-authored-by: jonschz <jonschz@users.noreply.github.com>

# Ghidra Scripts
|
|
|
|
The scripts in this directory provide additional functionality in Ghidra, e.g. imports of symbols and types from the PDB debug symbol file.
|
|
|
|
## Setup
|
|
|
|
### Ghidrathon
|
|
Since these scripts and its dependencies are written in Python 3, [Ghidrathon](https://github.com/mandiant/Ghidrathon) must be installed first. Follow the instructions and install a recent build (these scripts were tested with Python 3.12 and Ghidrathon v4.0.0).
|
|
|
|
### Script Directory
|
|
- In Ghidra, _Open Window -> Script Manager_.
|
|
- Click the _Manage Script Directories_ button on the top right.
|
|
- Click the _Add_ (Plus icon) button and select this file's parent directory.
|
|
- Close the window and click the _Refresh_ button.
|
|
- This script should now be available under the folder _LEGO1_.
|
|
|
|
### Virtual environment
|
|
As of now, there must be a Python virtual environment set up under `$REPOSITORY_ROOT/.venv`, and the dependencies of `isledecomp` must be installed there, see [here](../README.md#tooling).
|
|
|
|
## Development
|
|
- Type hints for Ghidra (optional): Download a recent release from https://github.com/VDOO-Connected-Trust/ghidra-pyi-generator,
|
|
unpack it somewhere, and `pip install` that directory in this virtual environment. This provides types and headers for Python.
|
|
Be aware that some of these files contain errors - in particular, `from typing import overload` seems to be missing everywhere, leading to spurious type errors.
|
|
- Note that the imported modules persist across multiple runs of the script (see [here](https://github.com/mandiant/Ghidrathon/issues/103)).
|
|
If you indend to modify an imported library, you have to use `import importlib; importlib.reload(${library})` or restart Ghidra for your changes to have any effect. Unfortunately, even that is not perfectly reliable, so you may still have to restart Ghidra for some changes in `isledecomp` to be applied.
