Using the answer from Easy way of loading projects with rebar dependencies , dependencies

  • 0

Using the answer from Easy way of loading projects with rebar dependencies, dependencies are now automatically resolved, but they are not automatically loaded.

So, how can I load all the modules in my ebin and /deps/*/bin path automatically? That way they are available when using the Erlang shell tab completion, which speeds up my dev process considerably.

My solution based on the great answer of Adam Lindberg: https://gist.github.com/1131312 It will only load the project modules automagically, so almost no delay in erl startup.

    This snippet would do the trick:

    [code:ensure_loaded(list_to_atom(filename:rootname(filename:basename(F))))
 || P <- code:get_path(), F <- filelib:wildcard(P ++ "/*.beam")].

    Put it in your ~/.erlang file as one row (including the dot: .) and it will be executed upon starting any Erlang shell. Be warned though, it’s hideously slow!
