static_files as an env variable is not good for releases

[elbrujohalcon]

Files in releases are placed under lib/cowboy_swagger-…/….
The proper way to find that path would be:

filename:join(code:priv_dir(cowboy_swagger), "swagger")

@elbrujohalcon we should discuss about this issue, if you take a look at the example code, there isn't any hack in code, the release was solved modifying the relx.config in order to copy the priv/swagger folder located in cowboy-swagger, to the priv directory of the app using cowboy-swagger. Check it out: https://github.com/inaka/cowboy-swagger/blob/master/example/relx.config#L7. I stay tuned.

@elbrujohalcon I tested it modifying the relx.config of serpents and it worked like a charm.

@harenson @cabol that works, but you're forcing your users to modify their relx.config just to get swagger working in the first place. I would rather not require any special configuration from the user to get this library to just work. If the users want to apply his patches to the assets, then they can set the static_files environment parameter in their configuration. If they don't, cowboy swagger just automagically works. 🌟
