Description

I have an Erlang package that I wish to test linked to a Gleam project, but this Erlang package is not published on Hex. If this was a Gleam package, I would be able to include it using my_package = { path = "../my-package" } but I it seems when such a package does not contain gleam.toml, it is considered invalid.

Whatever logic that is used to make a non-Gleam package from Hex work, could that be applied to a non-Gleam package from path or git dependencies so all three work the same way?

Contributor guide

Research direction
Investigate how non Hex Erlang packages are currently handled for Hex dependencies and extend that logic to path and git dependencies so that all three dependency types work uniformly.
