What it does
The versioning tool that will tell you if you broke your own contracts. testbump determines your semantic version based purely on the principle that your test suite is the versioning contract . No AST parsing, no complex rules, no dependency hell. Just pure Test-Driven Bumps (TDB) using Node and Git. Let C = Code, T = Tests. Let old = Last Git Tag, new = Current HEAD. 💥 MAJOR (Breaking): T(old) fails on C(new) . (You broke a previously guaranteed contract). ✨ MINOR (Feature): T(old) passes on C(new) AND T(new) fails on C(old) . (Old contracts are intact, but you added new tests/contracts that old code cannot fulfill). 🩹 PATCH (Fix): T(old) passes on C(new) AND T(new) passes on C(old) .…from github.com

I built a tool to get instant test results2022 · github.com · ▲96I got sick of the old software development loop: Change code -> Run tests -> wait -> wait some more -> look at failures. I decided to build a tool that will enable you to: Change code -> look at failures. No wait time, no explicit test running. Under the hood: - Runs the whole test suite and collects code coverage per test. - For each auto file save, analyzes the changes on the tests. - Runs changed tests in the background. - Display results, the loop time from change to test results is approx 250ms. Instead of: code -> alt+tab -> arrow up -> rerun all the tests -> wait ... -> test results…

The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate).

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
