Is it possible to hide documents of private modules?

[toku-sa-n]

Hi. After dune init project foo, I created lib/hoge.ml and lib/fuga.ml and modified lib/dune:

(library
 (name foo)
 (public_name foo)
 (modules hoge fuga)
 (private_modules fuga))

Then, I ran dune build @doc. As below, Fuga is listed, but I want not to list it as it is a private module.

I tried (modules Hoge Fuga)(private_modules Fuga) (capitalizing the first letter), but it didn't change anything.

Is it possible to hide it? If so, how to do it?

The version of my dune is 3.10.0.

Thanks.

Libraries in Dune are wrapped by default meaning that Dune will generate a foo.ml file which exports all the modules of the library. This is called the top-level module. The reason you see Hoge is because you are looking at Foo the top-level module that Dune created (with both modules). To fix this, you can make your own top-level module. Just create a file foo.ml with the following:

module Fuga = Fuga

On the other hand, we should probably make it so that private_modules are not included in the toplevel module. cc @rgrinberg
