JTB is a syntax tree builder to be used with the JavaCC (Java Compiler Compiler) parser generator.
JTB was originally developed at UCLA up to version 1.3.2 (JTB 1.3.2 and JTB < 1.3.2).
It has been upgraded in version 1.4.0+ (2009-2010), for a real life project - a translator for the Uniface L3G language (PROC) to Java, ran on 5000+ source files in less than 30 mn -, and has been embedded within the Eclipse JavaCC plugin.
From 2011 to 2016 it was also provided as a stand-alone tool in the same hosting environment as JavaCC (java.net), which closed.
Since 2017 it is also provided as a stand-alone tool in the same new hosting environment as JavaCC JTB at GitHub.
Version 1.5.0 brings interesting new features. See Overview page in Wiki.
Last update : Sept, 2023 - version 1.5.1 committed on GitHub (version 1.5.0 was never committed).
JTB needs a JDK 1.8+ since version 1.5.0.
Previous versions needed JDK 1.7+.
