ocamlbrowser
is actually the name of a program that has been distributed with the OCaml compiler for a very long time. It is written with LablTk, maintained by Jacques Garrigue, and was inside the "ocaml distribution" (instead of an external tool) because it accessed .cmi
files in ways that rely on internal details of the compiler.
So the short answer is: "yes, just call ocamlbrowser
in your terminal" (assuming your distribution packaged ocamlbrowser with the compiler, which may or may not be the case; there may be a separate ocamlbrowser package instead). The look&feel of the tool may be a bit dated compared to a shiny Eclipse version, but it indeed exists and works fine.
