[chuck-users] chuck 1.4.0.0, global keyword.

[Jack Atherton]

Hi!

1. It's possible that the Windows build of miniAudicle is a little behind.
I can't remember when it was built. Do things work in miniAudicle if you
use the (now-deprecated) "external" keyword instead of "global"?
1a. The dac-ugen-replacement branch holds a few extra features that are
used in Chunity but haven't been rolled into the main ChucK branch yet. You
could start building your application from either the master branch or that
branch, depending on your needs. (Check out chuck.h for a hint towards the
extra features -- it adds a few more global types.)
2. There is a github repo for Chunity but it's still private at the moment.
The place to start for developing a new application that embeds ChucK is to
make sure you have access to whatever calls you need from core/chuck.h,
built into whatever wrapper makes sense for your own application. Chunity
doesn't really do much more special than that on the C++ side, other than a
few gnarly nuances unique to Unity audio programming. I do think that the
global keyword is activated for all (new) builds of ChucK -- there are
quite a few tests for the command line version that use it. Sorry I don't
know much about ChucK Racks, maybe Spencer could chime in about that!

Best,
Jack
