Load all erlang modules in path

Question

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

Answer 1

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!

» time erl -noshell -s init stop
erl -noshell -s init stop  0.11s user 0.02s system 11% cpu 1.143 total # Without
» time erl -noshell -s init stop

Answer 2

if you spawn the process, you will get a very fast start.

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

in the ~/.erlang file
