Using uncrustify to fix code layout
We use uncrustify with a Fast Downward configuration file (.uncrustify.cfg in the repository root) to enforce some of our formatting conventions. If a source file is properly formatted, applying uncrustify should be an idempotent operation (i.e., result in an identical file). This is important so that we can verify our style rules automatically, at least for those rules which uncrustify can handle.
Please note that we require a specific uncrustify version.
wget https://github.com/uncrustify/uncrustify/archive/uncrustify-0.67.tar.gz tar -xzvf uncrustify-0.67.tar.gz cd uncrustify-uncrustify-0.67 mkdir build cd build cmake ../ make -j4 sudo cp uncrustify /usr/local/bin # Add binary to a directory on PATH.
To check the formatting of all C++ files, use ./misc/style/run-uncrustify.py. To actually edit the files that need to be uncrustified, use ./misc/style/run-uncrustify.py --modify. This script is also part of our tox tests:
sudo apt install tox cd misc/ tox -e fix-style
To check the style of Python and C++ files, you can use tox -e style.
