RText 2.0.6 was just released! Here’s a rundown of the major changes:
Syntax highlighting and code folding for JSON. Folks doing a lot of work with web applications will appreciate this.
Improvements to the UI when a Substance Look and Feel is installed. All trees and lists now use Substance’s striping and rollover effects, and colors used in miscellaneous custom components were tweaked to better fit in with the current Substance skin.
Fixed a ClassCastException when adding a JRE in the Java options panel. This was bug 3600567, and was accidentally introduced with the last refactoring of the Java language support.
Updated the Turkish and French localizations. Thanks to Burak and Pat!
A major side effect of the improved Substance support is that compilation is now done in two phases. RText has always only required Java 1.4, but Substance requires Java 6 or newer (we’re actually shipping with Insubstantial, which is an active fork of Substance, since the original author stopped working on it). To get around this, all of the “core” RText classes are built with Java 1.4, and all of the classes requiring Substance are built with Java 6; these classes are only referenced from the application via reflection to avoid a hard dependency. If Java 1.4 or Java 5 is detected, RText will never load anything Substance related.
When will RText drop support for 1.4? Probably not for awhile, especially when I can easily use functionality in newer versions easily enough via reflection as I’m currently doing (and only then for Substance, opening a browser/system editors for files, and for the scripting API). And performance improvements are received via simply running in a newer JVM, not from compiling with one. Perhaps when Java 8 GA is released this September, it might be time to consider moving to Java 5. :)
Anyway, the list of new features going into the next release is already growing! More on that soon.
