Sure thing, that's what we're here for :)

For details, I think it's best to discuss on IRC freenode #ruby-osx,
or via IM. My email address is where you can reach me on gtalk/jabber.

There wouldn't be much difference in total development time, so we've
discussed that for the time being they're gonna be developed
separately. Because much has to be done on both the libraries core
code, so it's not an ideal moment to devote time to merging them.

Discovering all bugs to be able to run Mocha and ERB (dunno the status
of the latter).

It already was possible to do most stuff from XCode. But, admittedly,
not being a huge user of XCode has lead me to never create xcode
templates. I would love input on this from users such as yourself,
because it _should_ be completely transparent.
Also, I would like to clarify that I did _not_ mean that HotCocoa/
Rucola would be a standard dependency of an application. I simply
meant that the test cases, which are run by devs anyways so not a
problem afaik, would require the test case helpers form the HotCocoa/
Rucola gem. The gem will come with MacRuby pre-installed. (At least,
that's what I remember the last discussion on this topic being
concluded at.)
So with your additions to the templates, this would still run that
way, we simply don't include any elaborate helper code. To summarize,
a standard template created app, would look identically to what your
additions do, with the exception from any test case helpers, these
should go into a shared test case helper.

Too much to list actually, but it surrounds meta code mainly, which is
probably why most simplere uses work. (Try running the test suites of
test::unit and minitest, see the rake tasks). More importantly, as
you've noted, test::unit is dropped by upstream in favor of minitest.
We however still have it in the stdlib and it's unsure as of yet what
and when this is going to change, so this could potentially make it
"hard" for users. Although I must admit, I have no experience in
porting test cases to minitest.

A comment, as a note that it's not stable yet, would already clarify a
lot yes.

True, we don't want that.

Well, it _is_ being worked on. The reason that might not be apparent,
is simply because it really _isn't_ stable yet and I always tend to
wait giving the idea something is "supported" (ugh I hate the
word ;) ) until we have something to show for it.
In other words, in my opinion, people should not expect everything to
work yet on MacRuby. If they know this upfront, then there's also no
reason to judge MacRuby on it and stop using MacRuby. Which is why I'm
telling all of this in the first place :)
So, since I do wholeheartedly agree with you that we don't want users
to bump into any walls, I'm gonna apply your patch right now, and we
will discuss further on the test case helpers as we go :)
HTH.
Cheers,
Eloy
PS: Dylan, please do contact me off list to discuss details,
preferably not by email, it takes me too much time to write them…
