This is one way that solves what you said. The problem with regexes is
how it will handle the cases you didn't say :-)
(for example, what do you want to match when there are more "ends" and so on).

irb(main):002:0> text =<<EOF
irb(main):003:0" def
irb(main):004:0"   test = 100;
irb(main):005:0"   puts test
irb(main):006:0"   (1..10).each { |i| puts i }
irb(main):007:0" end
irb(main):008:0" EOF
=> "def\n  test = 100;\n  puts test\n  (1..10).each { |i| puts i }\nend\n"
irb(main):011:0> m = text.match /def(.*)end/m
=> #<MatchData "def\n  test = 100;\n  puts test\n  (1..10).each { |i|
puts i }\nend" 1:"\n  test = 100;\n  puts test\n  (1..10).each { |i|
puts i }\n">
irb(main):012:0> m[1]
=> "\n  test = 100;\n  puts test\n  (1..10).each { |i| puts i }\n"

Hope this helps,

Jesus.
