+#
+# section-parse-insane.rb: scan standard input and do the following:
+#
+# 1. look for a section that begins with "test-text "STUFF/foo" and ends
+#    with a blank line.
+# 2. print the "bar.DIGITS" suffix for each line in the section
+#
+# Example:
+#   > cat input.txt
+#   test-text "blah blah blah garbage/foo"
+#   random crap bar.1
+#   random crap bar.2
+#   random crap bar.3
+#   random crap bar.4
+#   
+#   test-text "blah blah blah garbage/apple"
+#   random crap bar.1
+#   random crap bar.2
+#   random crap bar.3
+#   random crap bar.4
+#   > ./section-parse-insane.rb < input.txt
+#   bar.1
+#   bar.2
+#   bar.3
+#   bar.4
+#
+
+# section and row matches
+S = %r{^test-text "[^"]+/foo"\n((?:^[^\n]*bar\.\d+\n)+)^\s*\n}m
+B = /^.*(bar\.\d+)$/
+
+# extract section body, split by line, map to suffix, and print result
+puts(ARGF.read.scan(S)[0][0].split(/\n/).map { |s| s.gsub(B, '\1') })
