Question

Is there a better way to get the public “properties” of a Ruby object?

def props
  self.public_methods.grep(/.=$/) - ["==","==="]
end

Answer 1

Your regular expression is incomplete: it matches methods starting with any character, not just word characters. The best way to get all the "writers" is

methods.grep /^\w+=$/

And regex can be shortened to

methods.grep /\w=$/

but less clear.
