Sublpress: Manage WordPress Sites in Your Text Editor

Sublpress is a new extension for Sublime Text by Nic Dienstbier that makes it possible to manage your WordPress site (or multiple sites) in the editor. Currently you can edit settings, create and edit posts and manage taxonomy terms. All features can be easily accessed via the Command Palette.

I tested Sublpress in both Sublime Text 2 and beta of Sublime Text 3, and my initial impressions are it seems to be a bit more stable (ironically) in the latter. This could be just something relating to my setup however.

I’m still not entirely sure whether I want to manage my WordPress sites in my text editor, but if it sounds like fun to you, go get Sublpress on GitHub. 🙂

Debugging SASS in Chrome

In Firefox, viewing the original SASS line number directly has been possible using Firebug and FireSass. Similar, or even better functionality has very recently arrived in the stable release of Chrome. I just tried this out and it works wonderfully. See here for instructions:

How to make Chrome understand the SASS/SCSS in your rails app

Don’t worry about the Rails stuff, these instructions work just as well for stand-alone SASS. If you’re using Compass like me, you need to set sass_options = {:debug_info => true} in the config.rb file of your project.

If you look at your css files after doing the above, you’ll see they are quite a mess. From a comment by Paul Irish in the above post I learnt better stuff is on its way thanks to the upcoming SASS 3.3, and Source Map support in Chrome:

Exciting times!

The Mobile Book by Smashing Magazine

I’ve just finished reading through The Mobile Book by Smashing Magazine. The book is a fully packed 334 pages of analysis on the current state of mobile and best responsive design practices. Writers include gurus such as Peter-Paul Koch, Stephanie Rieger and Brad Frost.

Bottom line: most people working in web design today should probably read this book, whether they’re designers or developers. The book has useful data on today’s mobile landscape, discussion on how to bake responsive design into our processes, the peculiarities of designing for touch and instructions on how to optimize for mobile.

From the foreword (by Jeremy Keith):

There will come a time when this book will no longer be necessary, when designing and developing for mobile will simply be part and parcel of every Web worker’s lot. But that time isn’t here just yet.
Jeremy Keith

Here are my six key points I gathered from the book:

  1. The Internet of Things is a thing, and is likely to explode in the near future with more Internet-connected devices entering the market that are neither traditional mobile devices nor desktops or laptops. Some don’t even have screens.
  2. Responsive design that focuses only on screen size can result in huge downloads on mobile. We need to pay more attention to conditional loading of secondary content.
  3. Creating detailed Photoshop comps of web sites can set false expectations to clients and other stakeholders. Responsiveness should be part of the design process very early on.
  4. The capabilities of mobile browsers vary wildly (especially on Android), and browser/device detection is increasingly a necessary evil. RESS (Responsive design + server-side components) and server-side libraries like Detector (by Dave Olsen) are a possible solution.
  5. With new hybrid touch-enabled devices, we are less likely to be able to predict whether the user can use touch as an input method. Due to this we need to optimize for touch by default.
  6. Touch interfaces take web design into the realm of industrial design. It’s no longer just about how things look and behave, we also need to consider how people hold their devices. This has significance when deciding where to put key controls.

The Mobile Book is available here.

The print edition is probably the most high quality book Smashing Magazine has produced so far. A real pleasure to read!

Regarding point 2 in my list: I’ll be presenting a simple example on how to use conditional loading for any content in WordPress in an upcoming post. The same method is used on this site to load the sidebar. Edit: it’s now online, see Simple Conditional Loading in WordPress.

My Dev Setup, part 3: Browser Testing

Some years ago browser testing meant just testing in Firefox, Safari and possibly Opera, and cursing and testing in IE6. Good standards support in current browsers has made development easier on one hand, but more complex than ever on the other hand with the demands of responsive design, the rise of mobile and websites themselves becoming more advanced.

Now on the desktop we have to worry about Chrome, Firefox, Safari, Internet Explorer 7,8,9 & 10, and on ‘mobile’ there’s at least Safari for iOS (phone and tablet), Windows Phone, multiple versions of the Android Browser, Chrome for Android, the BlackBerry Browser, Firefox, Opera Mobile and Opera Mini.

This post describes a snapshot of my current browser test setup and it’s the third part in my “web dev on Mac OS X” series. The first two were about utilities and web development apps. I’ll try to keep this series of posts up to date as the tools of the trade change.

Latest versions of Chrome, Firefox, Opera and Safari

Google Chrome with Web Inspector

You should of course have all the latest versions of the most popular desktop browsers. Ideally it would be a good idea to have older versions too, but since both Firefox and Chrome update themselves automatically, this is not much of an issue (see Arstechnica’s browser share analysis from last October)

Since Firefox 3.6 was the last version not to be updated automatically, I like to keep it around, since it has quite a few issues with some HTML5 elements and CSS3. An easy way to install an old version of FF alongside the current version is via

Internet Explorer 7, 8, 9 & 10 in VMWare

IE 8 running in XP, IE 10 running in Windows 8

Internet Explorer testing is annoying, because installing multiple stand-alone versions of IE is difficult, and in some cases impossible. I currently have a VMWare virtual machine running XP with IE versions 6,7 and 8, installed using Multiple IE. Unfortunately this setup is somewhat buggy, but it works. I have a separate Windows 7 and 8 VM’s running IE 9 and 10 respectively. This can get messy and requires a lot of HD space. Also, testing local websites requires editing the hosts file of each VM.

Microsoft offers free VM images for IE7-10.

Mobile testing

The Real Thing

Testing on iPad, iPhone, Nexus 4 and Nokia E51

Testing on real devices is essential, and at least before going live I try to test on as many devices as possible. Since my own collection is limited (Android, iOS and S60) and there’s no open device lab near me, I occasionally visit the local department store and try out all the phones on display. Necessary, but not very practical for quick debugging.

Adobe Edge Inspect

Adobe Edge Inspect

For devices that support it (ie. Android and iOS), Adobe Edge Inspect is a great time saver. Basically it allows you to browse the same site synchronously on your desktop and your mobile via a mobile app and a browser extension. Even Edge Inspect doesn’t allow browsing local sites though, and that’s where the next solutions come in.

Opera Mobile Emulator

The Opera Mobile Emulator is an excellent and easy way to test a responsive web site in a huge number of different sized displays. It’s a useful tool whether your users use Opera or not.

iOS Simulator

Apple iOS Simulator

The free Mac OS X Developer Tools include an iOS simulator, which is at least 99% identical to the actual devices (iPhones and iPads). The emulator allows rotating the device, simulated shakes etc. This is probably the mobile testing tool I use the most.

Going forward: Remote virtual machines with Browserstack

Maintaining all these emulators is messy, to say the least. So I’ve been eyeing Browserstack, which allows testing in IE 6-10, recent versions of Chrome, Firefox, Opera, and best of all, emulators of most Android & iOS devices of significance. From my point of view the only thing missing is Windows Phone. Oh and Symbian would be nice too.

The interface is really easy to use and straightforward. You input the address you want to test, choose an operating system and browser, and that’s it. Using a remote desktop via a browser is of course fairly slow, but the really killer feature of Browserstack is the ability to test local sites (like This often makes Browserstack more convenient than the alternatives.

Browserstack is a subscription service (starting at $19 per month for an individual user). If you feel like trying it out, there’s a Microsoft-sponsored three-month free trial available. CrossBrowserTesting is another similar-looking service, although I haven’t tried it out.

Final Words

Browser testing is a complicated business, and your needs will depend on the type of site you’re developing and user demographic. Testing in more than one browser is a start, but mobile testing has also become a must. In a year or two it might even be more important than desktop browser testing, if it isn’t already.

Testing on a real device gives a good feel to the restraints of that device, but remember your iPhone/Samsung/Nokia model isn’t the only one out there. As more and more varied devices enter the market and testing needs get more complex, tools like Browserstack are likely to be the only realistic testing option for the vast majority of designers and developers in the future.

My Dev Setup, part 2: Web Development Apps for Mac OS X

In the second post of my “set up” series, I’m listing some of the apps I use daily for web development. The first part dealt with utility apps.

There are a multitude of tools available, and the specific ones you need will inevitably vary based on the kind of development you do, the languages you use, size of team etc. I do mostly front-end dev and WordPress theme + plugin development in a small team, so my choice of apps obviously reflects this. Also keep in mind that the industry is moving fast and in 12 months time we might all be using an entirely different set of tools.

Text Editor: Sublime Text 2

Sublime Text 2

I’ve written about Sublime Text in an earlier post, but I’m still going to mention it. It’s one of the best code editors out there at the moment, if not the best. Highly extensible, there are plenty of good additions relating web development and WordPress.

Get Sublime Text 2 here:

CodeKit for Sass & Compass


Sass is a robust CSS preprocessor that runs on Mac, Windows and Linux/Unix, and I’ve used it pretty heavily for the last 2 years. It allows extending CSS with variables, nested rules, logic, inheritance and mixins, among other neat things. It can be installed and run just fine from the command line as a Ruby gem, but recently we’ve started using Codekit, a marvellous app which takes care of compiling Sass (or Less/Stylus/HAML/Coffeescript etc) into final code in a nice, GUI-configurable fashion. It will also refresh your browsers automatically on save, combine + compress JavaScript and even optimise image files.

Version Control: Tower & GitBox

Tower screenshot

After having used Git for the last couple of years, it’s almost hard to imagine web development without some kind of version control. Learning at least the basics of git on the command line is most certainly recommended, but day-to-day I find a good GUI client is very handy. For many small projects the simple and elegant Gitbox (, 13.99 € on the Mac App store) is quite enough, but for most projects I use Tower (, 49.00 €).

I’ll be expanding on how we use Git in WordPress projects in a later post.

Diff with Kaleidoscope

Kaleidoscope screenshot

Sometimes (ie. often) you get conflicts when merging somebody else’s code with your own. A good merge tool helps, and for the Mac you can use either the free FileMerge included in the Mac OS X Developer Tools, or the excellent Kaleidoscope. Kaleidoscope used to be just a really good (and pretty) file comparison tool, but in its latest version 2 beta it includes merging capabilities for text and folders.

PHP Error Monitoring: Console


Thanks to my excellent colleague Marco, I’ve discovered how useful the built-in OS X can be for tracking down PHP errors when doing local WordPress development. This allows you to easily view any errors without printing them out using WP_DEBUG and messing up everything.

MySQL Admin: Sequel Pro

Sequel Pro

For both local and remote MySQL administration, there’s nothing better than Sequel Pro. And it’s free.

WP-CLI for command-line WordPress

WP Cli running in a terminal

When developing multiple WordPress sites locally or remotely, activating and deactivating plugins and themes via the admin interface can become tedious. For geeky-minded people, there’s WP-CLI, a simple command-line interface for creating and managing WordPress installations. Quoting from the website:

You can update plugins, set up multisite installs, create posts and much more.

That’s all! In the next post in this series, I’ll look into my browser testing setup.
