Hello, I apologize in advance if this question is silly. I'm playing
around with chicken because a) it is scheme and b) it offers tight
integration with existing libraries. In particular, I want to do play
around with Window's sound and GUI APIs.
But right now I'm doing some testing on Linux, because I haven't quite
figured out how to install MinGW and MSYS properly yet. In any case,
here's a little test that uses the `dollar' FFI egg:
(use dollar)
(define (c-test)
($ printf "Hello Chicken, from C!"))
If I compile this using `csc -s test.scm', I get a shared library, which
I can then load from `csi' using the command `(use test)'. I can then
evaluate (c-test), as expected.
Now, supposing I wanted to change the c-test to:
(define (c-test)
($ printf "BOO!")
The question is: am I obliged to recompile outside of the REPL loop? In
other words, is there a `compile' command which lets me recompile
test.scm from within the REPL? This would allow me to do more
incremental development -- and would make me less likely to separate FFI
calling code from other code (whether or not that's a good idea is
another question ;)
Couple of other questions, while I'm at it:
- Is quack generally preferred over hen in emacs? Quack looks pretty
good; haven't tried hen yet. Keep in mind that I will be using windows
eventually.
- When I download the readline egg, I get nice command completion on the
csi REPL -- sweet! Unfortunately, it doesn't seem to work within emacs
(quack), either in the REPL or when editing a scheme file. Is there any
way to make this work?
Many thanks in advance,
Martin
