I've been considering the Earthly build automation tool as a replacement for Make in my project. I have a mono repo with a root Makefile, that has a target that scans for subfolders with Makefiles, and builds those with
make -C some_subfolder.
Looking at the documentation for Eartly, the only way I can see to support those builds is to make a static lists of subfolders, and then build them using the example from the mono repo documentation, like
FROM alpine:3.13 all: BUILD ./some_subfolder+all BUILD ./another_folder+all
I've been through the rest of the guides, and I can't see any way to make that list of build instructions dynamic, without writing a wrapper script to run Earthly. Has anyone else had this issue and come up with a solution?
