One-line function definitions

Ruby
1

I’m converting some code from Python to Ruby and can’t figure out the
syntax
for one-line function definitions in Ruby. For example, what would this
line
be in Ruby?

def GetAnthologyTitle ( data , prefix ): return GetField ( data ,
prefix ,
‘ANTHOLOGY-TITLE’ )

Transliterated (counting cultural differences), it owuld become:

def antology_title (data, prefix); get_field(data, prefix,
‘ANTHOLOGY-TITLE’); end

But more importantly, it probably wouldn’t exist, since ruby culture
sees explicit getters/setters as repeating yourself and finds
meta-solutions, a-la attr_accessor or def_delegator.

def jim(x) y=foo(x); bar(y) end
p jim(12)
