  • Show HN: Git-coverage to open test coverage in a web browser
    Hi! I made a small tool to open test coverage uploaded to Codecov[1] in a web browser with a few helpful flags: - branch: A target branch - path: The specific file - remote: An upstream Frequent clicks through the same paths and manual changes to the URL was a solid motivation for me. Learning more about Zig was a nice happening too. Not sponsored but that'd be cool ;) [1]: https://about.codecov.io. - Source: Hacker News / about 1 month ago
