Use several modules in OCaml utop
ocaml, ocamlbuild, ocamlfind
Solution
`#use a.ml` executes every statement in a.ml just as if you had typed those statements in the toplevel directly. Thus, you do not get a `module A` defined, so your other file cannot have things like `A.foo`. If you want `module A`, you must first byte compile a.ml, and then `#load a.cmo`.
Problem
I'm reading an OCaml project recently and I want to put the source files in the utop so I can do some experiments. Suppose I have two files amodule.ml, bmodule.ml. bmodule.ml will use functions defined in amodule.ml, for example, bmodule use Amodule.anyfunction() where anyfunction() is defined in amodule.ml. I want to put both of them in utop: ``` #directory "/directory contain amodule.ml and bmodule.ml" #use "amodule.ml" #use "bmodule.ml" ``` And this doesn't work because Amodule is a module name base on the amodule.ml file and the utop don't know these things, I think. So how I can put these files in the utop without changing the file content？
