Bravo! I haven't read the code carefully yet to fully understand the details of the implementation, but this is brilliant hackery. As someone who has recently developed a focused interest on build systems, I have noticed the large vacuum in the space for a content-based Make-like that has a similarly low of a barrier of entry. HN user bobsomers said it well the other day: "There is a much tighter, cleaner, simpler build system within Bazel struggling to get out. A judicious second take at it with a minimal focus, while taking some of the best ideas, could be wildly successful I think." https://news.ycombinator.com/item?id=32831890 https://news.ycombinator.com/item?id=32831890 I think 'redo' is probably the closest contender these days. apenwarr's redo implementation is probably the most popular, the most mature, and has been built with a lot of smart design choices: https://redo.readthedocs.io/en/latest/ https://redo.readthedocs.io/en/latest/ Pluggable caching, which AFAIK apenwarr/redo does not yet support, would be a great addition, to support remote, shared caching.
