Running executable and inline tests in watch mode at them same time for Advent of Code

[benjamin-thomas]

For such simple setup, you can build yourself an adhoc build/run pipeline with an external tool, see:

Running tests when using dune build watch-mode

An alternative to running dune in watch mode is to use entr to create an ad hoc builder/watcher. Something like this: find ./lib/ -name "*.ml" | entr -c bash -c 'dune build && echo OK' This won’t lock any files, so you can reload your dune utop process more easily that way.

Hope that’s clear enough
