phantom_sahi.js

if (phantom.args.length === 0) {
    if (phantom.args.length !== 1) {
        console.log('Usage: phantomjs sahi.js URL');
        phantom.exit();
    }
    else {
        phantom.state = 'sahi';
        console.log(phantom.args[1]);
        phantom.open(phantom.args[1]);
    }
}
else {
    console.log(document.body.innerText);
    phantom.exit();
}

condition in line 2 seems really strange.
anyway thanks for this helpful gist.
