In my dune file, I have a rule similar to this:
(rule
(deps (universe))
(targets "foo")
(action (with-stdout-to "foo" (echo "a " (= 1 2) "\n")))
)
But the above does not parse (Error: Unexpected list).
I’d like to tell Dune to evaluate the expression (= 1 2) (resulting in false), then print it as a string (so the output would be a false\n).
Is it possible to do so?
