Is there something like bpython for Ruby?

IRb is pretty plain compared to bpython, even when using wirble.

Is there any ruby equivalent of bpython?

Use Pry: http://pry.github.com

It is written from scratch and let's you:

• view method source code
• view method documentation (not using RI so you dont have to pre-generate it)
• pop in and out of different contexts
• invoke at runtime, in any context
• syntax highlighting
• gist integration
• view and replay history
• open editors to edit method using edit-method obj.my_method syntax

A tonne more great and original features
