JFlex is free software and contributions are welcome.
The preferred way to contribute code changes or fixes is via github pull requests. Before you send a pull request, please make sure that unit tests and regression test suite pass.
We provide help on how to set up your development environment.
Short version:
./run-tests
This runs the entire test suites, including unit and regression tests, as well as examples.
Longer version:
Unit tests are run automatically if you locally install the jflex package for instance via
mvn3 install
The regression test suite must be run from the directory
testsuite/testcases, for instance with
mvn3 test
The jflex/examples can be run individually either by calling make or mvn test.
If you have larger code changes or new features to contribute it is usually a good idea to get in touch with the developers first and discuss if your idea fits with the rest of the JFlex design. You can get in contact either on the github issue tracking system or the JFlex users mailing list.
