New project: the GNUstep developer guide

I discovered by searching the interwebs that a significant number of people who try out GNUstep get stuck at the “I wanted to do Objective-C on my Linux so I installed GNUstep…now what?” stage. There are some tutorials for GNUstep around, but they’re not necessarily easy to find, and not necessarily pitched at beginners. Otherwise, […]

The problem with not-Apple

I’ve read a few articles over the last week or so that point to the Mac having lost its shine among developers. There was a time when the first things you did when you wanted to be a developer on the Free Software platform Ruby on Rails were that you bought an Apple PowerBook and […]

Updating my ObjC web app on git push

I look at SignUp.woa running on my Ubuntu server, and it looks like this. That title text doesn’t quite look right. $ open -a TextWrangler Main.wo/Main.html $ make $ make check $ git add -A $ git commit -m “Use new main page heading proposed by marketing” $ git push server master I refresh my […]

Automated tests with the GNUstep test framework

I’ll create a folder for my project, then inside it a folder for the tests: $ mkdir -p TemperatureConverter/test $ cd TemperatureConverter The test […]

Conflicts in my mental model of Objective-C

My worldview as it relates to the writing of software in Objective-C contains many items that are at odds with one another. I either need to resolve them or to live with the cognitive dissonance, gradually becoming more insane as the conflicting items hurl one another at my cortex. Of the programming environments I’ve worked […]

Garbage-collected Objective-C

When was a garbage collector added to Objective-C? If you follow Apple’s work with the language, you might be inclined to believe that it was in 2008 when AutoZone was added as part of Objective-C 2.0 (the AutoZone collector has since been deprecated by Apple, and I’m not sure whether anyone else ever adopted it). […]

Using GNUstep libraries with Xcode

I was recently asked about building projects that use GNUstep from Xcode. The fact is, it’s incredibly easy. By default, GNUstep on Mac OS X installs its libraries to /usr/local/lib and its frameworks to /Library/Frameworks. Therefore if you want to include GNUstep-base additions, you just hit the + button in your target’s “link binary with […]
