limescript for bip backlog timestamp translation

backlogTime.coffee

# remove the timestamp that bip inserts in a backlog message and set the time
# of the span element that limechat uses
bind 'line', (line) ->
  # see if out message matches 'hh:mm:ss>'
  html = line.innerHTML
  regex = /(\d{2}:\d{2}):\d{2}>/
  matches = html.match regex
  return unless matches

  # remove that timestamp from the message
  message = line.querySelector('.message')
  html = message.innerHTML
  html = html.replace regex, ""
  message.innerHTML = html

  # and add hh:mm to the .time span
  # for some reason replacing the html wasn't working, so I'm removing the
  # element and creating a new one instead
  $(line).find('.time').remove()
  $(line).prepend('<span class="time">' + matches[1] + '</span>')
