⁠Code formatting

For code formatting we use google-java-format⁠. Following steps are required for optimal dev experience in IJ:

1. Download google-java-format plugin⁠
2. Set custom VM options required for IJ plugin⁠
3. Go to Settings > google-java-format and click Enable google java-format (should be checked by default)
4. Go to Settings > Tools > Actions on Save and enable Reformat code and Optimize imports for Java files

Each save should automatically trigger reformat.

If you want to debug the CLI check on macOS:

wget https://github.com/google/google-java-format/releases/download/v1.23.0/google-java-format_darwin-arm64
chmod a+x google-java-format_darwin-arm64
chmod a+x .github/scripts/check-google-java-format.sh
./.github/scripts/check-google-java-format.sh                                                                                                                     

or if you are on Linux:

wget https://github.com/google/google-java-format/releases/download/v1.23.0/google-java-format_linux-x86-64
chmod a+x google-java-format_linux-x86-64
chmod a+x .github/scripts/check-google-java-format.sh
./.github/scripts/check-google-java-format.sh        

You can also run the following command to fix formatting for the whole project:
