XMP

< Object 1 instance methods 1 class methods

An example printer for irb.

It’s much like the standard library PrettyPrint, that shows the value of each expression as it runs.

In order to use this library, you must first require it:

Example

require 'irb/xmp'

Now, you can take advantage of the Object#xmp convenience method.

Example

xmp <<END
  foo = "bar"
  baz = 42
END
#=> foo = "bar"
  #==>"bar"
#=> baz = 42
  #==>42

You can also create an XMP object, with an optional binding to print expressions in the given binding:

Example

ctx = binding
x = XMP.new ctx
x.puts
#=> today = "a good day"
  #==>"a good day"
ctx.eval 'today # is what?'
#=> "a good day"
