Dejal Open Source

Like anything else, source code can get a bit untidy and crusty after a while. My Cocoa code is about a decade old now, so it's been well overdue for a cleanup. I have just completed a process of reorganizing all of the source code for future Lion and iOS 5 editions of Dejal projects.

One of the changes was to rename the open source and shared code to use a "Dejal" prefix rather than "DS" as before. Although I could have left the old prefix, the new one fits better with Apple's naming guidelines: they reserve all two-letter prefixes for themselves.

I also rearranged the code. I used to have separate Subversion repositories for iOS and Mac projects. Now I have code for iOS, Mac and cross-platform mixed in a repository, since there is a lot of code that works on both platforms.

Another big change was to move the open source projects from Subversion to Git. I've long resisted Git, but it really seems the most popular version control system for open source projects. And GitHub is a very nice way to share Git projects, with handy online viewing of documentation and source code, plus useful additions like issue tracking.

So now my open source projects are hosted on GitHub. You can view my GitHub page. Initially I have two iOS projects there: the small DejalView (formerly DSView) project, plus the very popular DejalActivityView (formerly DSActivityView) project. I will add more over time.

These projects have been updated for iOS 5 and ARC, plus general code improvements. They also have new README and license files. They use a standard BSD license.

I also took this opportunity to redesign the Dejal Developer page. The design was inspired by Matt Gemmell's excellent open source page (I got his permission to copy his design, but it ended up somewhat different).

Take a look at the new pages:

  • Dejal Open Source: the main Developer page, with general information at the top, followed by information on each project (with more to come).
  • Dejal Open Source License: a summary of my intention with the license for the source code, suggested attribution format, and the legal text.
  • Developer Store: enables you to donate in appreciation for the open source, or buy non-attribution licenses.

This last is interesting — the open source is available completely free, provided that you give Dejal credit in your app's About view, documentation, or website. If the code helps you, it's often nice to give something back, so now you can express appreciation via a donation or (just for fun, also inspired by Matt) a gift from my Wish List. But if you can't or don't want to give credit, you can purchase licenses that allow you to use the code without having to give credit. Hopefully that'll cover everyone's needs, but if you have some other requirement, let me know.

I hope you find my open source code useful. Keep an eye out for future additions; I have a Mac project coming soon (a feature that will appear in Time Out 2).
