Question

def get_type
  x = [{:type=>'A', :patterns=>['foo.*']}, {:type=>'B', :patterns=>['bar.*']}]

  name = 'foo.txt'

  result = x.each { |item|
    item[:patterns].each { |regex|
      puts "Checking #{regex} against #{name}"
      if !name.match(regex).nil?
        puts "Found match: #{item[:type]}"
        return item[:type]
      end
    }
  }
end

result = get_type
puts "result: #{result}"

Expected output:

Checking foo.* against foo.txt
Found match: A
result: A

However, all I see is:

Checking foo.* against foo.txt
Found match: A

My current work around is this:

def get_type
  x = [{:type=>'A', :patterns=>['foo.*']}, {:type=>'B', :patterns=>['bar.*']}]

  name = 'foo.txt'

  result = []
  x.each { |item|
    item[:patterns].each { |regex|
      puts "Checking #{regex} against #{name}"
      if !name.match(regex).nil?
        puts "Found match: #{item[:type]}"
        result << item[:type]
      end
    }
  }
  result[0] unless result.empty?
end

Why doesn’t the first approach work? or maybe it is ‘working’, I just don’t understand why I’m not getting what I’d expect.

Answer 1

Works fine for me. Are you actually invoking it with

result = get_type puts "result: #{result}"

? Because that shouldn’t work at all, though I’m assuming there’s a linefeed that got eaten when you posted this.
