Hello Robert,
you are right, you can not directly call procedures from modules/units
compiled with -block.
A trick I used to "export" procedures was to have two compilation units
(I used modules for both). One, the "hook", defining and exporting top
level bindings, which is not compiled in

Hi Jeff and all of you,
one in a while I wonder how to handle a list of eggs not suitable for
certain situations due to some undocumented internals.
Examples like "egg used global variables" vs. "application uses egg
from multiple threads" come to mind.
Or the case with the "synch" egg, which,
Hi Christian,
this might be a case of "never trust a statistics you did not falsify
yourself".
Not bothering to speculate about explanations, I tend to ask how stable
the results are wrt. larger N's, repetition etc.
IMHO the results are too close for a call. Roughly this looks like 91%
memory

Hi all,
I tried to package an egg exporting a functor.

`include` is literally copied to the .import.scm file
The actual code of the functor is in its own file, which is included here

Those are then not installed, which makes chicken-install barf at the

Maybe it makes more sense to have the -n switch only in effect for the egg

Hi all,
I need to specify a certain - not yet available - version of chicken
itself as the minimum requirement for an egg to work for real.
(((Backgground: Hacking away on this RPi gpio egg I created a version
which exacerbates an issue I fixed the other day - see ticket 1232. To

Hi all,
for the time being (as we shall not have yet another gpio egg).
There is a 1.1.0 version of the raspberry-pi-gpio-small egg now here:

Argh, wait...

Hi all,
yet another egg I put together, which may be interesting to you (and may
go the coop):
http://askemos.org/chicken-eggs/raspberry-pi-gpio-small.release-info
This is a (supposed to be) API compatible version of the
raspberry-pi-gpio egg.
Maybe these modifications should simply be
There are many, each having it's own strength. It really depends on
what you are looking for.
I'm using ball.askemos.org . (Actually much of it I wrote.)
Now this was originally done in rscheme about 15yrs ago. It's not
monolithic, but consists of communicating actors/agents (which may be
Hi,
I'd like to cond-expand code depending on whether or not the code is
compiled with interrupts disabled.
Is there a feature I can test? (Can't find any. Did I miss it?)
Thanks
/Jörg
PS: Currently I use my own feature to cond-expand into a declaration to
disable interrupts. But the

Hi,
I just released the "hopefully" egg: Composable transactional memory.
API inspired by Clojure's ref's and STMX.
Currently only some record types may be used with hopefully. Further
versions should add other mutable types.
I'd love to get feedback on the API.
Hi,
I always assumed that (make-hash-table eq?) would create a hash table
usable with arbitrary chicken objects as keys.
That is especially structures like objects created via define-record
should be valid as keys. That is: referencing the table using the very
same object (comparing eq? to the
reading the srfi-69.scm source) that the
eq?-hash procedure produces a different hash value for the lookup before
and after the mutation. Hence the lookup fails while walking the tree
succeeds.
