Module `Ocaml_plugin__.Ocamldep`

val find_dependencies : prog:string -> args:string list -> working_dir:string -> target:string -> string list Async.Deferred.Or_error.t

Call ocamldep to recursively find dependencies for the target compilation unit, return a list of compilation units the target depends on in topological order.

Failure cases includes:

cannot run ocamldep.opt
invalid working_dir, target not found
ocamldep errors (the program crashes, syntax errors, etc.)
cyclic dependency detected

A compilation unit is a string representing an ml/mli module. It does not contain the extension. Example:

       file              compilation unit
       a.mli?            "a"
       Stack.mli?        "Stack"
       /path/to/file.ml  "file"
       /other/file.ml    "file"

This function assumes that the target and all its dependencies are located under the same directory, that is working_dir, and that an .ml and an .mli for the same module have the same case.
