Hi folks,
I just finished porting gEDA (http://www.gpleda.org/) to Guile 2.0!
I encountered one problem, though.
In Guile 1.8.x, scm_display_error() takes a stack as the first
argument. In Guile 2.0.x, scm_display_error() takes a frame as the
first argument.
Can anyone suggest a sensible way to support both? I haven't been able
to figure out a good feature test... at the moment I've had to resort to
passing #f. :-(
Peter

What about provide two interfaces and dispatch them by checking
scm_major_version? Just suggestion. I'm not sure whether it's a proper
way.

How about executing a fragment of Guile code that calls display-error,
and seeing if it throws an exception?
scheme@(guile-user)> (false-if-exception (begin (display-error (make-stack #t) (current-output-port) "a" "b" '() '()) #t))
$2 = #f
scheme@(guile-user)> (false-if-exception (begin (display-error (stack-ref (make-stack #t) 0) (current-output-port) "a" "b" '() '()) #t))
ERROR: In procedure make-stack:
ERROR: In procedure a: b
$3 = #t

Hi Peter,
Sorry for the terrible delay here.

Yay!

I have re-added support for passing a stack as the first argument. It
will produce a deprecation warning at runtime though.

You could manually check the (effective-version)... not so nice, but oh
well.
