Discovering Ruby object members?

What is an easy way to find out what methods/properties that a ruby object exposes?

As an example to get member information for a string, in PowerShell, you can do

"" | get-member

In Python,

dir("")

Is there such an easy way to discover member information of a Ruby object?

Solution 
  • "foo".methods
