rebar3_path_deps

A rebar plugin to specify path dependencies.

Over time, your project is growing significantly in size! It’s gotten to the point that you probably want to split out a separate OTP applications for others to use.

This plugin add to rebar the supports of path dependencies which are typically sub-applications that live within one repository.

Build

$ rebar3 compile

Use

Let’s start off by making a new OTP application hello_utils inside of your project hello_world:

# inside of hello-world/
$ rebar3 new app hello_utils

This will create a new folder hello_utils inside of which a rebar.config and src folder are ready to be useed. In order to tell Rebar about this, open up hello_world/rebar.config and add hello_utils to your dependencies:

{deps, [
  {hello_utils, {path, "hello_utils"}},
  ..
]

This tells Rebar that we depend on an application called hello_utils which is found in the hello_utils folder (relative to the rebar.config file it’s written in).

and then add the plugin to your rebar.config:

{plugins, [
    rebar3_path_deps
]}.

Then just compile your application

$ rebar3 compile
