Dune is "a composable build system for OCaml" with out-of-the-box support for ReasonML. Dune can be used for a lot of things, but in simplest terms it can be used to compile ReasonML programs into native executables.
Considering the following ReasonML program.
/* hello_reason.re */
print_endline("Hello, Reason!")We can then create the following Dune build file.
;; dune
(executable
(name hello_reason))If we then run dune build hello_reason.exe, then Dune will compile the
hello_reason.re into a hello_reason.exe executable that can be found in
build/default. Run it and see the output.
