Yes, you mentioned using jpython for a debugger interface, and I thought
about it. It seems to me that there are two sorts of interface; one for
scripting, and one for plugins. I don't think it is possible to do a debugger
with just a scripting type interface (like jpython) - you need to be able to
instantiate widgets and so on for the UI, interact with signals for setting
breakpoints.

BTW - what does the new ctags stuff do? I thought you had ported the
ctags parser to use the KDevelop class store - but I can't find any code to do
that. I'm keen on KDevelop Ruby support, and I see this in ctagsdlg.cpp:

static CTagsKindMapping kindMappingRuby[] = {
    { 'c', I18N_NOOP("class")               },
    { 'f', I18N_NOOP("function")            },
    { 'm', I18N_NOOP("mixin")               },
    { 0  , 0                                }
};

What is it all about, if that isn't a silly question?
