Ruby script to convert lines from my IRC-Skype relay bot to be as though they were spoken in IRC.

skype_to_raw.rb

require 'set' 

TIMESTAMP = /^(?<timestamp>[-0-9 :]{19})/
BOT_NAME = /\tSkyBot\t/
SKYPE_MSG = /#{TIMESTAMP}#{BOT_NAME}<(?<nick>[^>]+)>(?<text>.*)$/
SKYPE_ACTION = /#{TIMESTAMP}#{BOT_NAME}\* (?<text>.*)$/

# NICK = /([\w\-\\\[\]\{\}\^\`\|]+)/
# Characters that can't be in a nick
NOT_NICK = /[^\w\-\\\[\]\{\}\^\`\|]/

def clean(nick) 
  nick.gsub(NOT_NICK,'_')
end

nicks = Set.new 
updated_files = {}

# Reformat all normal messages and collect a list of nicks who speak
Dir.glob("vore_merge/*").each { |filename| 
  File.open(filename) { |file| 
    updated_files[filename] = []
    file.each_line { |line| 
      if line =~ SKYPE_MSG

      else
        updated_files[filename] << line
      end 
    }

puts nicks.inspect

# Transform all actions from nicks who have spoken.
