Contributing to the project

This is the contribute.md of our project. Great to have you here. Here are a few ways you can help make this project better!

Adding new features

Please open an issue here to discuss the feature you would like to see in Libasciidoc. If you’re in the mood to implement it (that’s awesome!), then submit a pull-request along with enough tests (both at the parser level and at the renderer level) to validate the behaviour of your code. When submitting a pull-request, please follow the AngularJS Commit Message Conventions.

Don’t get discouraged if you don’t get an immediate response, this is a side-project.

Bug triage

  • You can help report bugs by filing them here.

  • You can help us diagnose and fix existing bugs by asking and providing answers for the following:

    • Is the bug reproducible as explained?

    • Are the steps to reproduce the bug clear? If not, can you describe how you might reproduce it?

    • What tags should the bug have?

    • Is this bug something you have run into? Would you appreciate it being looked into faster?

  • You can close fixed bugs by testing old tickets to see if they are still happening.

  • You can update our changelog here:

  • You can remove duplicate bug reports by:

Beta testing

Testing existing features is a good way to contribute to the project, too!

Benchmarking

This project uses Ginkgo as the main testing framework but uses the standard Go toolchain for benchmarking and performance comparisons.

Since we use Ginkgo, it’s generally a good idea to skip the normal tests when running benchmarks. To do that, use something like go test -run=XXX to skip normal tests (assuming no test contains "XXX").

It’s also a good idea to run multiple iterations of the benchmarks to avoid anomolies and gather better statistics.

Example command:

go test -run=XXX -bench=. -benchmem -count=10 ./... | tee tmp/bench-branch1.txt

After making changes to your branch, run the same benchmarks and save to a second file:

go test -run=XXX -bench=. -benchmem -count=10 ./... | tee tmp/bench-branch2.txt

Compare results using benchstat. Example output:

$ benchstat tmp/bench-branch1.txt tmp/bench-branch2.txt

The go-test and benchstat output don’t need to be committed to git since they are heavily dependent on the local system running the benchmarks at the time, but it may be helpful to include relevant benchstat output in git commit messages.
