By using Ruby's Bindings, you can find a lot of stuff :-)
After requiring memory_dump, insert the following line anywhere in your code:
dump{}
This will give you a nested Hash containing most variables accessible from where you called it, as well as a few other interesting tidbits:
{:instance_variables=>{"@instance_variable"=>"instance var's value"},
:class=>YourClass,
:local_variables=>{"local"=>"local var's value"},
:class_variables=>{"@@class_variable"=>"class var's value"},
:ancestors=>[YourClass, YourMom, Object],
:backtrace=>['you_get_the_drift.rb']}
If you're ready for an explosion of (very interesting) information, call it in verbose mode:
dump(:verbose){}
dump(:v){}
Included in the previous hash will be two additional hashes of name-value pairs. One containing all the global variables and the other one containing all the accessible constants.
Note: all keys for buckets generated by the tool are symbols. All other keys (variable names, constants, etc) are strings.
