Here's an easy way to solve a problem that may have nagged you as it did me. Simply using
foo.inspect to dump out some object to the browser dumps one long string which is barely useful except for short strings and the like. The ideal output is already available using the
PrettyPrint module so we just need to use it.
to quickly debug some possibly large object (or collection) can get old fast so we need a shortcut.
<%= PP.pp(@something, '') %>
Taking the definition of
Object#pp_s from the extensions project it's trivial to create a helper method to just dump out an object in a reasonable manner.
def dump(thing) s = StringIO.new PP.pp(thing, s) s.string end
Alternatively you could do as the extensions folks do and actually define
Object#pp_s so you can use it in your logs or anywhere else you may want to inspect an object. If you do this you probably want to change the
dump helper method accordingly in case you decide to change
pp_s in the future.
class Object def pp_s pps = StringIO.new PP.pp(self, pps) pps.string end end
