non-pretty-printed output by p is:
#<PP:0x81fedf0 @genspace=#<Proc:0x81feda0>, @group_queue=#<PrettyPrint::GroupQueue:0x81fed3c @queue=[[#<PrettyPrint::Group:0x81fed78 @breakables=[], @depth=0, @break=false>], []]>, @buffer=[], @newline="\n", @group_stack=[#<PrettyPrint::Group:0x81fed78 @breakables=[], @depth=0, @break=false>], @buffer_width=0, @indent=0, @maxwidth=79, @output_width=2, @output=#<IO:0x8114ee4>>
pretty-printed output by pp is:
#<PP:0x81fedf0 @buffer=[], @buffer_width=0, @genspace=#<Proc:0x81feda0>, @group_queue= #<PrettyPrint::GroupQueue:0x81fed3c @queue= [[#<PrettyPrint::Group:0x81fed78 @break=false, @breakables=[], @depth=0>], []]>, @group_stack= [#<PrettyPrint::Group:0x81fed78 @break=false, @breakables=[], @depth=0>], @indent=0, @maxwidth=79, @newline="\n", @output=#<IO:0x8114ee4>, @output_width=2>
I like the latter. If you do too, this library is for you.
pp(obj)
output obj to +$>+ in pretty printed format.
It returns nil.
To define your customized pretty printing function for your classes, redefine a method pretty_print(pp) in the class. It takes an argument pp which is an instance of the class PP. The method should use PP#text, PP#breakable, PP#nest, PP#group and PP#pp to print the object.
