ferd / app_deps.erl
Created September 23, 2012 05:33
Quick escript to generate a visualization of app dependencies in Erlang/OTP.
%%% Run with 'escript app_deps.erl'
%%% Change the path in filelib:wildcard/1 as required to capture all
%%% your dependencies.
%%%
%%% Rectangular nodes will represent library apps (no processes involved)
%%% and the circular nodes will represent regular apps. An arrow going from
%%% 'A -> B' means 'A depends on B'.
%%%
%%% This script depends on graphviz being present on the system.
