I am doing various modifications to my NGINX Magento server and part of this is to do front end optimisations
I am currently using a CDN plugin to host my JS but Magento always calls JS lines (huge massive calls to JS libariries which looks ugly in the code view) that I want to combine to one line.
I know you can use Admin > Developer to merge JS files but I dont want to do this. I want to make this:
<script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/prototype/validation.js"></script>
<script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/scriptaculous/builder.js"></script>
<script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/scriptaculous/effects.js"></script>
<script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/scriptaculous/dragdrop.js"></script>
<script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/scriptaculous/controls.js"></script>
<script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/scriptaculous/slider.js"></script>
<script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/varien/js.js"></script>
<script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/varien/form.js"></script>
<script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/mage/translate.js"></script>
<script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/mage/cookies.js"></script>

<script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/varien/configurable.js"></script>
<script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/calendar/calendar.js"></script>
<script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/calendar/calendar-setup.js"></script>
Change to
<script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/prototype/validation.js"></script><script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/scriptaculous/builder.js"></script><script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/scriptaculous/effects.js"></script><script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/scriptaculous/dragdrop.js"></script><script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/scriptaculous/controls.js"></script><script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/scriptaculous/slider.js"></script><script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/varien/js.js"></script><script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/varien/form.js"></script><script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/mage/translate.js"></script><script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/mage/cookies.js"></script><script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/varien/product.js"></script><script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/varien/configurable.js"></script><script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/calendar/calendar.js"></script><script type="text/javascript" src="http://dz36xlwnpud7z.cloudfront.net/cdn/210393/js/calendar/calendar-setup.js"></script>
I think is what you're looking for. I tested this with Magento 1.9.2.1.
In this file Mage_Page_Block_Html_Head, function getCssJsHtml() on line 210 character 112-119 you'll find this . "\n". Remove that from the function and your JS files will be rendered in one line as you requested.
Keep in mind not to modify core files but to extend the class and override only this function to maintain rest of functionality.
