Hi,

I have now polished and tested the rewrite of the hygiene system enough that I feel confident to release it. Hopefully it doesn't introduce too many bugs. Changes/new features include:

• Rewritten hygiene system.
• The installation procedure has changed slightly, see the README.
• The bugs with let-syntax and letrec-syntax are now zapped
• It now writes warnings about missing symbol names when loading compiled modules
• I added a better README for the github page
• Better tests. Not good, but better.

With this, I hope that the problems with hygiene are fixed. There are still a couple of bugs, for instance with DSSSL parameter scoping, but they are not design flaws. The "only" big thing that remains now is to implement the syntactic tower.

Have a look at http://github.com/pereckerdal/blackhole/

Hi,

Thanks for blackhole. I'm getting some errors when I run `gsc build`. Attached is build.log file. Am I doing something incorrectly?

My Gambit-C version is v4.6.0 20100115040636 x86_64-unknown-linux-gnu "./configure --enable-single-host --enable-gcc-opts --enable-multiple-versions"

Thanks, Jeff

Great news! I just installed the latest version and it build just fine and seems to be working fine except that I have some problems with nested macros.

If I have the following files:

;; File a.scm (define-syntax when (syntax-rules () ((when exp block ...) (if exp (begin block ...)))))

;; File b.scm (import a)

(define-syntax foo (syntax-rules () ((foo id) (let ((id #t)) (when id 'foo)))))

(foo bar)

Then running module b.scm gives an 'Unbound variable: a#bar'
