Include erlang ffi modules on .app file for releases to work with gleam apps #3710

cd repro
gleam export erlang-shipment 
cat build/erlang-shipment/gleam_stdlib/ebin/gleam_stdlib.app

The modules list is missing gleam_stdlib for being an erlang ffi module.

Same problem applies to hex tarballs *.app.src files.

Smells like Nerves support.

High priority it is

Leaving some notes from me digging through the codebase:

It seems like compiler-cli/templates/gleam@@compile.erl would need to be updated to not just return ok/error, but also the module names of successfully compiled modules. BeamCompiler.compile would then return that to PackageCompiler.perform_erlang_codegen, which after some reordering could then write an app file containing both gleam sourced modules as well as erlang/elixir ffi sourced modules.
