Call graph generator for OCaml or Reason

Question

I want to analyze a OCaml/Reason code repository and understand calls between various functions. Is there a tool that provides such functionality?

Answer 1

I actually never used it but only thing I can remember for OCaml is pfff. Readme says that it supports codemaps and codegraphs.

Answer 2

One of the option is to take advantage of the existing OCaml editors or IDE since you can re-use their parsers to obtain the parsed tree or AST tree. I'm aware of two relatively good IDE for OCaml, which are:

• OcaIDE (written in Java)

• Merlin (written in OCaml)
