Q: I've a directory with examples and I want build all of them easily?
R:
You can use an .itarget file listing all products that you want.
$ cat examples.itarget
examples/a.byte
examples/b.byte
$ ocamlbuild examples.otarget
You can also have a dynamic rule that read the examples directory:
$ cat myocamlbuild.ml
open Ocamlbuild_plugin;;
dispatch begin function
| After_rules ->
let examples =
Array.fold_right begin fun f acc ->
if Pathname.get_extension f = "ml" then
("examples" / Pathname.update_extension "byte" f) :: acc
else
acc
end (Pathname.readdir "examples") []
in
rule "All examples"
~prod:"examples.otarget"
~deps:examples
(fun _ _ -> Command.Nop)
| _ -> ()
end
$ ocamlbuild examples.otarget
