I did say more coming soon, right… So here’s another. This time it’s the SnS Minifier Extension found at: [https://secure.svnrepository.com/s\_swanki/open/radiant/extensions/sns\_minifier/tags/latest](https://secure.svnrepository.com/s_swanki/open/radiant/extensions/sns_minifier/tags/latest) Again, early release (v0.1) so please give me feedback. From the README file: = Styles 'n Scripts Minifier Adds the ability to minify CSS and JS files. This way, you can keep your code the way you like it in the editor but serve up minified files. (And if you really want to speed things up, add GZip to the mix to have your server crunch it further). == Available Minifiers - JSMin v1.0.0 - This is based on the original C code by Douglas Crockford ([JSMin](http://www.crockford.com/javascript/jsmin.html)) but wonderfully repackaged into a plugin by Ryan Grove ([GitHub - rgrove/cssmin: 💀 Ruby library for minifying CSS. Unmaintained.](http://github.com/rgrove/cssmin/tree/master)). JSMin is often seen as being an older but safer technology. It certainly doesn’t pack as well as some others out there but is tried and true. - CSSMin v1.0.0 - This is Ryan Grove’s port of the YUI Compressor’s ([http://www.julienlecomte.net/yuicompressor/](http://www.julienlecomte.net/yuicompressor/)) CSS minifier (which was itself taken from Isaac Schlueter’s regular expression based CSS minifier ([Isaac Z. Schlueter](http://foohack.com/2007/09/squish-it-good-code-compression-for-the-masses/)) Ryan nicely ported this one to a plugin too. And I added a minor addition too (which is available via options – see below) - Packr - James C. was nice enough to port Dean Edward’s famous Packer ([/packer/](http://dean.edwards.name/packer/)). More about the plugin version used here can be found at: ([http://blog.jcoglan.com/packr/](http://blog.jcoglan.com/packr/)) Packer is a great tool but it is pretty strict about terminating javascripts with semicolons ([/packer/usage/sample.html](http://dean.edwards.name/packer/usage/sample.html)). - Rainpress - This is a newer ruby project by Uwe L. Korn to minify CSS files ([Google Code Archive - Long-term storage for Google Code Project Hosting.](http://code.google.com/p/rainpress/)). There isn’t much history but it seems solid enough. I had to repackage this one into a plugin (and strip a lot of the command line stuff out). Originally I did all this as I didn’t know about CSSMin. Anyway, I included this too basically because I’d already done everything. == Usage It’s pretty simple, really. Once installed, it adds a “Minify?” checkbox to the bottom of your Stylesheet and Javascript pages. Just check the box and save the file. Viola, the content is minified. The configuration can be changed via the @@settings variable inside: /lib/text\_asset\_mixins.rb There, you can choose which minifiers you want to use and set any of their available options. == Requirements You’ll need: - Radiant v0.6.7 or higher - Styles 'n Scripts Extension v0.5 or higher == Installation Install the extension in your Radiant project like: [your project]/vendor/extensions/sns\_minifier You will need the Styles 'n Scripts extension installed for this to work and you will also probably need to change your project’s environment.rb file to twiddle the load order (the SnS Extension must be loaded before this one). For example, you could use something like: config.extensions = [:all, :sns\_minifier] == To Do Well first of all this extension needs some specs. But after that I’d _love_ to find where someone ported the YUI Compressor (JS version) to ruby. It appears to be much more flexible (read forgiving) than Packer while still crunching stuff way down. A second option would be to let admins install the java version and make this plugin interact with that. ---

If you rename this extension to styles\_n\_scripts\_minifier (or rename styles\_n\_scripts to sns), you won’t need the change in environment.rb. I was poking around in the SVN repo last night and spotted these new extensions. They look great! – Tim G. ---

I got the following error for /admin/css/new: undefined method `minify’ for #Stylesheet:0x2756ac8 (I’m on OS X 10.5, Rails 2.1, Radiant 0.6.7 using SQLite3) When I rake db:extensions:sns\_minifier:migrate, the add\_column never gets executed. I renamed sns\_minifier/lib/tasks/minify\_extension\_tasks.rake to sns\_minifier/lib/tasks/sns\_minifier\_extension\_tasks.rake and remigrated (migrate VERSION=0 then migrate), and it was fixed. I am now enjoying SASS-filtered, minified stylesheets. Thanks a bunch, Chris! – Tim G. ---

I had debated naming the new extensions “styles\_n\_scripts\_xxx” but I’ve decided that carpal tunnel syndrome just is not for me. But I hadn’t considered renaming the whole extension to “sns” though. I think I like that idea for several reasons. However, it would require users to physically change something on their servers – not just update from svn. You would have to change from: /vendor/extensions/styles\_n\_scripts to: /vendor/extensions/sns Would anyone be opposed to my renaming the extension like this? -Chris P.S. Just to be clear, I’d only be renaming files and their related code. Oh, and rake tasks would now be “rake radiant:extensions:sns” But otherwise everything would be _identical_ to your users (even the extension name in the Admin panel would still show “Styles 'n Scripts”). ---

I think renaming the whole thing to SnS would be in-line with your preference against carpal tunnel syndrome 🙂 None of the models would be renamed (right?), so users should be able to swap out the existing extension directory for a renamed one and get off without a hitch. If I had a few spare moments, I’d try it for myself right now… maybe there’d be a clash with the version number in the extension\_meta table, and maybe there wouldn’t because it’s listed as “Styles 'n Scripts”. – Tim G. ---

New release! You can find v0.1.1 at: [https://secure.svnrepository.com/s\_swanki/open/radiant/extensions/sns\_minifier/tags/latest](https://secure.svnrepository.com/s_swanki/open/radiant/extensions/sns_minifier/tags/latest) Thanks to Tim who found this naming issue (see below). What can I say - it was getting late. -Chris ---

No, I can keep the “Styles 'n Scripts” name in the meta table and in the Admin-Extensions page. So all that would be needed is for the user to update to the latest version of SnS and to change the “styles\_n\_scripts” folder name to “sns”. (Or change the /vendor/extensions folder’s properties if using svn:externals). But for me it does require renaming all the rake tasks, the xx\_extension.rb file, and probably something else I’m not thinking of. I’d also probably change StylesNScripts::Config to SnS::Config (and there would be a _bunch_ of references to that that would need to change accordingly). Not strictly necessary but something I’d want. -Chris
