Comment/Devbug traverser ruby Script

Hello all,
i need some help, having never herd of ruby before i joined my workplace im now saddled with alot of scripts written in ruby and i need to find out how to debug certain things (values of array's hashes etc). What i need is how to view each step in this command in a log file:

traverser.proc_node(proc_tree, 'root', Hash.new, Hash.new, verify_action.method(:Run), 0, 1, @loadset_hash)

do i do something like:
Log(LogLevels.normal, traverser.proc_node(proc_tree, 'root', Hash.new, Hash.new, verify_action.method(:Run), 0, 1, @loadset_hash) )??? :wall:
