♻️ waste-not

waste-not is a caching system for build pipelines, meant to enable tools to incrementalize their work. It supports caching based on changes to a single file, as well as based on changes to any upstream file in the dependency graph.

The waste-not package itself is a small integration of a set of subcomponents, also hosted in this repo. In addition to the main package, the waste-not repo comprises:

• A lightweight, extensible AST walker and visitors for extracting dependencies from files.
• A dependency resolver that converts dependencies into valid, normalized file paths.
• Dependency graph logic that finds all of the direct and indirect dependencies for each file.
• Cache-building utilities that abstract out file-system interactions for a higher-level caching tool.

⚠️ WARNING: This tool is still very much a work in progress. It is neither stable nor production-ready.
