This open tool helps to read and modify a java source code. Variable highlighting and navigation
significantly simplify understanding the variable usage evolution.

It supports different highlight
colors for class attributes, method parameters and local variables,
supports java 1.4 syntax.

In this version: fixed critical Swing/SWT synchronization problems, improved event handling. Thanks to Markus Hampel for the detailed bug report and testing..

Highlighted variable occurrence navigation

Alt-Left moves the cursor to the variable declaration
Alt-Up moves the cursor to the previous variable occurrence
Alt-Down moves the cursor to the next variable occurrence
Alt-Right moves the cursor to the original position, where the navigation has been started

Highlighted variable renaming

Ctrl-Alt-R renames a variable in all its occurrences, any changes can be discarded using undo


The highlight colors can be configured in Tools/Editor Options/Color/
Screen element/Variable highlight.

The tool can be enabled or disabled at any time using
Tools/Editor Options/Editor/Variable highlighter options.


Copy the varhigh-jbuilder-v1.2.2.jar to your JBuilder/lib/ext directory.
If you upgrade from the previous version, please remove the old varhigh-jbuilder-XXXXX.jar


The core component is the java syntax parser. It has been generated by
Java Compiler Compiler (JavaCC) - The Java Parser Generator based on the Java1_4c.jj
syntax grammar contributed by Sriram Sankar, David Williamns, Andrea Gini and Marco Savard.

I would like to thank all people who sent me bug reports and improvement wishes.
