My Workflow

Automating simple checks and providing helpful information can make a noticeable difference on a quality of life of a project maintainer. As an enthusiastic Go developer and open source contributor I assembled a library of tools to ease my life.

This library contains Makefile includes and GitHub Actions. Go project can import github.com/bool64/dev to receive versioned helpers. GitHub Actions are copied into the project with make github-actions (or make reset-ci).

Changed lines of code

Sometimes pull requests are big, this is usually not great, but might be unavoidable in some cases. This action comments the distribution of changed lines by type, so that it is easy to understand the scope (for example if largest part of PR is in JSON mocks).

API Changes

It is important to avoid unnecessary breaking changes or at least be aware of them. This action leverages gorelease to comment severity of API changes.

Test Coverage

Having meaningful test coverage increases confidence. This action will show the difference of coverage for every changed function, so that developer can see where some more effort is needed.

Benchmark Difference

When high performance is important, this action will help to see degradation or improvements to inform further decisions.

Automated Binary Builder

For command line tools it is convenient to delegate binary releases to GitHub Actions, maintainer only needs to create a new release, building and uploading happens automagically.
