Been attempting to try out Martin's jruby-debug code from debug-commons
and haven't been able to get much of anywhere. I assume I'm missing
something rather obvious, but I have not been able to get it to load. I
had to make a small change to jruby trunk for Martin's code to compile
(making RubyThread constructor protected instead of private) and then I
was able to compile and build a jruby-debug.jar file. However, how is
this library designed to be loaded? I tried the obvious, doing require
'jruby-debug.jar' in a ruby script. This didn't work, as the code that
tries to find a java extension library expects to find a class that
implements BasicLibraryService, whereas the jruby-debug code has
RubyDebugBaseLibrary which implements Library (not
BasicLibraryService). It appears the right way to use this code would
be to have it added using registerBuiltIn in Ruby.initLibraries so it
will be used when any code does require 'ruby_debug.so'. Is there a
different way to do this other than adding a line to Ruby.java?
Hi Chris,
this is exactly what I did. I have patched JRuby's trunk on my disk in
a way you described[1].
To be honest I did not care too much about the best integration with
JRuby since it does not prevent me from working on jruby-debug at all. I
would start to solving this after there is something usable for JRuby
users which is far from true in the meantime.
Looking forward to your patches, contributions! ;)
Regards,
m.
PS: I'll add note about this to the jruby-debug's README.
