Excessive recompilations when nothing substantially changed

…And I tried it. Does what it promises. My problem is that the project I am participating in is huge (1100+ Elixir files) and the output isn’t giving me a direct feedback what to address because the transitive dependency chains are like 40+ nodes.

Have you given DepViz a try?

I spoke about it at Code BEAM BR last year (in english): https://www.codebeambr.com/video/12

I noticed that a simple alias M can make the containing file compile-time depend on the file defining M.

That is not quite accurate, an alias will only cause a run-time dependency. However, compile-time dependencies are transitive so if A->compile-time->B and B->run-time->C, then when C changes, A will need to be recompiled.
