In plain words

Trunk is a linting platform that consolidates multiple code analysis tools into a single interface. It allows developers to run various linters and formatters without managing individual configurations. The tool is designed for teams who want to standardize code quality checks across their projects while reducing setup complexity. Trunk supports numerous popular linting tools and languages, making it useful for projects with diverse codebases.

From the sources

Speed up CI by eliminating test re-runs while continuing to collect stack trace info on failures. Stay on top of flakes with test summaries in PRs and integrations with tools like Slack and Linear. Spot duplicate failures and get AI summaries of what went wrong. Stop main from turning red. Stop CI costs from spiraling. Stop waiting in a serial queue. Failed PRs stay in queue while downstream PRs test. If a later PR passes, both are merged. Batch up to 100 PRs in one run. When a batch fails, auto-bisection isolates the culprit - no manual debugging. Create parallel lanes for non-overlapping changes. Hotfixes jump the line without cascade rebuilds. We would have never known how many flaky…from trunk.io

    Hi HN community, I’m Zach, founder and CEO of Warp, and am excited to show you Warp, a fast Rust-based terminal that’s easy to use and built for teams. As of today, Warp is in public beta and any Mac user can download it. It works with bash, zsh, and fish. The terminal’s teletype-like interface has made it hard for the CLI to thrive. After 20 years of programming, I still find it hard to copy a command’s output; I always forget how to use `tar`; and I always have to relearn how to move my cursor. To fix fundamental accessibility issues, I believe we need to start innovating on the terminal,…
