JavaScript Debugging
NEWSFLASH... The JS debugger for Mozilla is: Venkman.
Overview
The JavaScript Debugging project includes a cross platform debugging support
module for the Netscape JavaScript engine, a Java-based GUI debugger for
JavaScript, a JavaScript logging tool, and a console debugger. Work is beginning
on a new debugger, written in JavaScript, for the XPFE/NGLayout Mozilla.
Parts
- a native library in
js/jsd
which exposes a C language interface. This library wraps debugging
functionality exposed by the core engine and manages much of the bookkeeping.
This code is used in mozilla and can also be used in the standalone JavaScript
shell (js/src/js.c) or when the core engine is used elsewhere.
- native code in
js/jsd/java
to reflect that C language interface into Java. This implements the
native Java methods of
js/jsdj/classes/netscape/jsdebug
which itself implements the Jave interface for JavaScript debugging shipped with
Navigator 4.x in the Java package
netscape.jsdebug
and used
by the Netscape JavaScript Debugger - a tested compiled version of which
can be freely downloaded at
http://developer.netscape.com/software/jsdebug.html.
- a standalone console debugger written in JavaScript in
js/jsd/jsdb.
This system exposes the JSD interface into JavaScript and implements a
dynamicly modifiable and self-debugging debugger in JavaScript.
- the entire tree under
js/jsdj
holds various Java-based pieces of the debugging system. This includes the
buildable source to the Netscape JavaScript Debugger in
js/jsdj/classes/com/netscape/jsdebugging/ifcui,
a test system, JSLogger (an applet to track and log JavaScript activity in
the client), a Java-based console debugger, and other stuff.
Getting and building the code
The sources are available via CVS.
