    -r, --rc        callback file location (default is ~/.webtailrc)

You can define your custom callback into ~/.webtailrc. The code in ~/.webtailrc is executed when a new line is inserted.

$ cat ~/.webtailrc
var line = $('pre:last');
var text = line.text();

if (text == '\n') {
  line.css({
    margin: '3em 0',
    height: 1,
    background: 'lime'
  });
}

if (text.match(/CACHE|Load/)) {
  line.css({
    color: '#E1017B'
  });
