Dune - How To Export All Modules In Folder

I have a project where I want to access all the modules in a directory from different packages. Currently, the directory in question is like:

|- a.ml
|- b.ml
|- c.ml
|- lib.ml

Instead, of writing the following in lib, the main export of the directory:

module A = A
module B = B
module C = C

I use the following in my dune file:

   (name lib)
   (modules a b c))

Is there any wildcard or regex I can use with Dune to specify “export all the modules in this folder as visible”? Instead of specifying every file by hand. I haven’t really found anything in the documentation about this

You don’t need to do either. Exporting all modules from Lib is Dune’s default behaviour.

If you get rid of the lib.ml file it will just export every module. (Then you can just get rid of the modules stanza in your dune file.)
