Mix Project Without a lib path

Question

I have an existing ruby project that contains a list of protocol-buffer definitions. I would like to setup a mix.exs file and generate a hex package based on those same protocol-buffer definitions.

I can't seem to find out how to configure my mix project to use something other than the ./lib directory for containing my .ex files. That directory is already use by the ruby project for packaging the ruby gem so I would like to use a ./elixir_lib directory when I'm packaging this project.

Anyone know how to change the mix.exs file to tell it to use something other than ./lib?

Answer 1

Found it by digging through the elixir source code. In the project/0 function of your mix.exs file you can just set elixirc_paths: ["./elixir_lib"]. The default value is ["lib"], but I've moved it to use ["./elixir_lib"] in my project.
