Guys,
This sounds like an awesome list of stuff, but a feature that I think
would help a lot of with JRoR projects would be to improve the debugging
experience. Right now the only way to get JRuby on Rails debugging to
work in NetBeans is by setting an undocumented property in a config
file. And even then, it's quite buggy. From what I understand Netbeans
needs to have the fast debugger supported in JRuby before this situation
will improve. I would be willing to lend a hand on this if someone
could point me in the right direction. I've done a ton of Java and am
doing more Ruby all the time, but I'm not too familiar with the
internals of JRuby or how this would need to work.
Hey, an offer of help! That's what I like to see!
Basically, fast debugging in JRuby is just waiting for someone to
implement a ruby-debug library port. The plumbing is basically there in
JRuby already to support it, and I stubbed out most of the Java code
that would be required to hook it up (somewhere in SVN), so it's really
just about hooking up the functionality.
On the down side of debugging, the compiled code currently doesn't fire
all the various hooks needed to response to debugging or profiling
libraries.
In the short term, that just means that debugging code will run a bit
slower, since it won't use the compiler. But that's far from
unusable...the interpreter still performs pretty well, and debugging
doesn't have to run at full-speed anyway
Long term, I will probably bite the bullet and add in the appropriate
hooks. But not right now.
So basically, you should get familiar with the ruby-debug library, take
the stub code I implemented, and run with it. And try to get others to
help you; this is a fairly ugly gap in our Ruby support.
