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
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
