So I spent a bit of time today getting together the overdue release of Deelang ready, and finally pushed the 0.22 binary releases to Google Code, with source releases staying on GitHub. The Google Code project has now been fully migrated over to GitHub, and remains only to host binary downloads for those that want … Continue reading Deelang 0.22 released on GitHub!
After spending all their lives so far on Google Code, I've decided it's time to move both Deelang and ORMDroid over to GitHub. The projects have moved away from the old Subversion VCS and are now using Git, and the actual moving of the wiki pages, issues and everything else is well underway. Why the … Continue reading Deelang & ORMDroid: Moving to GitHub
As previously mentioned, I planned to spend yesterday rewriting Deelang's parser with the aim of fixing some long-term issues and revisiting some design decisions that get in the way of the DEX compiler. As it turned out, I didn't have as much time as I wanted to spend on this (as usual!) but I did … Continue reading Rewriting Vs. Rewriting
In response to a feature request from some of the guys here, my current work on Deelang focusses on implementing proper equality and comparison operators as part of the language. The current release has no support for operators beyond basic arithmetic - equality and comparison have traditionally been implemented as methods hacked on top of the standard … Continue reading Biting the bullet – time for a rewrite
After about a month of coding (on and off), The Deelang DEX compiler is now feature complete, and what better way to celebrate than by releasing the code? It's always been available in Subversion of course, but now you can download all the new stuff from the downloads page as either a source package or ready-made … Continue reading Deelang 0.20 released!
During a recent discussion, I had the need to show some numbers demonstrating why Deelang needs the new DEX compiler. As I said in that thread, it's all about removing reflection from the compiled classes. We all know that "reflection is slow" (for some value of slow) and especially on Android, that it isn't generally a … Continue reading Dex vs Dee VM – A microbenchmark
Further to my previous post, I've been working this week on the new native compiler for Deelang on Android. This is a drop-in replacement for the standard custom bytecode compiler and VM that compiles Deelang scripts directly to Dalvik Executable (DEX) bytecode for use on the Dalvik VM used in Android. Development has moved fairly … Continue reading DEXing Deelang – On a real device!
If you're one of the few who've already taken a look at Deelang, you'll know that it's a simple scripting language that compiles to a custom bytecode format, which then runs in a simple virtual machine. It can run anywhere, but is targeted mostly for embedded devices, and especially for Android. All this is fine, … Continue reading DEXing Deelang – First steps in SVN
After a few months in Subversion, with a few folks playing with the code and seeing what use they can make of it, the first file release of Deelang is now available from the project's downloads page. This release is still a very early public release (as denoted by the 0.18 version number) but is … Continue reading Deelang – First file release available to download
