  • @jvperrin Are you aware it's the same guy? He is trying to programatically delete entries in his `routes.rb` file. He was told it's just a text file, so now we have this... Check out his example text. – Substantial Feb 17 '14 at 08:04

ruby code in txt file?

Pretty much hard-coding..

  1. Read and store content into a variable using File.read(*path*)
  2. Split contents based on /n (new line)
  3. Loop each line and split then match the content
  4. On true push empty space, join file with \n
  5. Save and close the file.
