Hi,
I've been following the rdt mailing list for a while, and I'm glad
to see that RDT seems to be very active. I'm particularly interested in
jruby, since I'm using it and the lack of a debugger is a big pain. So
I'm just wondering if we're getting closer to that objective
Ricardo,
I know, I've been writing some JRuby code in the past few weeks, and
debugging with 'puts' is annoying, That's why I looked at the debugger
connection of RDT and JRuby; I believe you saw the discussion on
jruby-user, and the problems (a deadlock in tracing code) are fixed in
the upcoming JRuby 0.9.2.
Debugging JRuby with RDT is possible (I got it to work under ... let's
say 'lab conditions'). I'm working to bundle this up nicely so it's
possible to just run some JRuby code from RDT and have Debugging just
work (TM) if you use JRuby 0.9.2. The RDT debugger uses a Ruby debugger
implementation that doesn't quite work with JRuby (some regex don't
work, and there's some other small stuff).
I'm working on a JRuby plugin that adds special support for JRuby to RDT.
At the moment I have:
- Code Browsing
clicking on the org.foo.Bar in include_class org.foo.Bar goes to
the right class;
- Text Hovers
primitive, but docs for fully qualified class names can be shown;
- JRuby Launch support
This is useful in that I hacked RubyInterpreter and CommandExecutor to
use an Extension point; this allows a JRuby CommandExecutor which
sets the JAVA_HOME of the Java process, and - if the started Ruby code is
inside a JDT Java project - sets the CLASSPATH variable (this means, the
launched JRuby process will have the CLASSPATH of the Java project all set
up, so all libs will be visible)
TODO:
- an action that will allow to a) set the Ruby nature and builder on JDT
projects and b) set Java nature and builder on Ruby projects;
- proper JRuby debugging support; I got a proof of concept for this, but
need to figure out how to integrate it properly;
- maybe some templates for include_class or similar constructs;
- tie a bow around it
Some of these things need a few small patches to RDT, but I hope to get
this done before the end of the year.
Remember, Release early and often is a principle of open source projects.
Sounds like you've already got a lot of value...
