Question

Is there any way to increment a no. each time the file gets executed in ruby.
I didn’t find anything in this matter.
I want to declare a no. and then it will be incremented each time the file in which it resides gets executed.
I can use file to keep track of last no. used but is there any simple solution

Answer 1

# 0 TIMES
def  get_no
  me = File.read(__FILE__)
  me.sub!(/ \d+ TIMES/) { |s| " #{s[/\d+/].to_i + 1} TIMES" }
  l=me.split("\n")
  File.open(__FILE__,'w') { |f| f.write(me) }
  return l[0][/\d+/]
end

This method will give me next no each time I call it and also will keep track of it thanks to Alex D
