gudetama

Next-level CI optimization for lazy (fast) builds

what

gudetama lets you avoid re-running steps in your CI pipeline when there's no need to run them again.

but how

First you declare all the things that can affect the outcome of a particular CI step. They can be files, env vars, tool versions, or anything you can write to stdout. Then before running that particular CI step, gudetama compares the current values of those things against their values on a previous successful build. If any of them changed it lists the differences, and re-runs the step. If none of them changed gudetama skips the step. If any files were supposed to be generated and passed to later steps, gudetama will restore them from a cache of the previous build.
