Try to copy text between two know string

Hello,

I have a sample text, like this;

eg;
def
test = 100;
puts test
(1…10).each { |i| puts i }
end

how can I copy the text in range between ‘def’ and ‘end’, which are
test = 100;
puts test
(1…10).each { |i| puts i }

into a variable.
I’ve tried using ~/def … ~/end but not matched

Hi Ahmad,

def methode_name
test = 100;
puts test
(1…test).each { |i| puts i }

(1…test).each { |i| puts i } # 1 to 100

end

puts methode_name

This is one way that solves what you said. The problem with regexes is
how it will handle the cases you didn’t say :slight_smile:
(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.

Thank you, it did helped me.
Actually I’ve tried using the same regex as you use, which is
/def(.*)end/, however i overlooked the m in the end of /
Thank you

Just for the record: the m regex modifier means “multiline” and makes
the dot match the newline character.
