如何使用混合包运送非Elixir文件？

Question

I'm building a library in Elixir which processes XML-files of some kind. I'd like to ship DTD schema with it, cause that XML-files refer to it inside of <!DOCTYPE> . How do I do so that it all worked being imported by another app.

Generalizing: how do I ship some static non-elixir files (resources) that are being used by mix project?

The usual place to put non-source code files that are required at runtime is the /priv directory at the root of the package alongside /lib or /config . The compiler maintains the proper references and makes sure the directory is always available in the appropriate place when accessed through:

Application.app_dir(:my_app, "priv/path/to/file")
