ducktape
I want something lighter than github to watch and build some projects on change. I'm going to call it ducktape. It's a bash script that will have an array of projects. It will have a configurable delay. It will loop over all the projects, fetch from upstream, and if there is a change fetched, it will merge and build.
First Pass
For this to work, any project it watches must have a T383838Makefile. And some standard targets.
Since it wont completely use a fresh repo on each run (I'm bandwidth constrained) each project must have a T383838clean target.
Since my note repo has a T383838publish target, I'll make that required, too.
And then a default target is needed, which will be used to determine if the T383838publish target is called.
Well, that sounds easy enough.
First pass is done. Embedding a copy here...

Second Pass
For my second pass, I want to use containers that use an overlay on the existing checkout and build everything in place in the clean environment. Or at least, I certainly want to experiment with that. It would be nice to use NixOS containers instead of docker containers, just to see how those work.
Actually, I should make use of NixOS to get the dependencies and such as well.
