gl and glut

[Eduardo Cavazos]

Hello,

I noticed that gl and glut libraries were added to Jazz recently. Very nice!

Is it possible to "load" them into a Jazz repl interactively? I.e.

~ # jazz
JazzScheme v2.1.3 beta

> (... type something here to load gl)

That feature was in fact added a couple weeks ago! See the message: "Library require / import / export now special forms" for details.

With it, you can now enter the following at the console to get access to opengl functionality:

(import (jazz.graphic.opengl))

Hmmm, is there a way to get this to work at a jazz repl started at a
shell? I get an error when I try that:

~ # jazz
JazzScheme v2.1.3 beta

There is no such thing as "a jazz repl started at a shell". When you run jazz.exe you are running a Gambit repl exactly as if you had started gsi but with some code already loaded to implement the Jazz module system. That is why it doesn't understand the Jazz language.

For (import (jazz.graphic.opengl)) to work, you have to use the Jedi repl. Note that creating a minimal app that would be just a single window with a Jazz repl in it for new comers to do quick experiments would be a nice project.
