DingsDa Parsers for the file formats of the game Wargame Red Dragon from Eugen Systems.

Wargame: Red Dragon Parsers

This is a collection of parsers for the gamefiles of the game "Wargame Red Dragon" by Eugen Systems.

They may or may not work for previous / future games in the series.

The parsers are written in Python 3.11 and use the dingsda library for parsing the gamefiles, a fork of the Construct library.

The parsers are not complete yet, if you encounter any issues, please open an issue on GitHub.

Usage

pip install wgrd_cons_parsers

# unpack gamefile
python -m wgrd_cons_parsers.edat NDF_Win.dat
# repack gamefile from the out/ directory
python -m wgrd_cons_parsers.edat -p out/NDF_Win.dat.xml

Performance

Currently unpacking the everything.ndfbin uses about 14 GB of RAM and takes about 2 minutes on my machine.

It is recommended to use the pypy3 Python runtime, because it significantly increases the performance:

Development

If you want to change the scripts easily, you can install them locally:

git clone https://github.com/ev1313/wgrd-cons-parsers.git
cd wgrd-cons-parsers
pip install -e .

# unpack gamefile
python -m wgrd_cons_parsers.edat NDF_Win.dat
# repack gamefile from the out/ directory
python -m wgrd_cons_parsers.edat -p out/NDF_Win.dat.xml

With this setup you can modify the scripts and still use them.

Tests

For running the tests, a working Wargame Red Dragon installation is required.

Install the wgrd-cons-tools and run the unpacker on the gamefiles:

python -m wgrd_cons_tools.unpack_wgrd <path-to-wargame-red-dragon> -o tests/files/

Then run the tests:

cd tests
pytest --pdb *.py
