                     ======== TFP 2016 ===========

           17th Symposium on Trends in Functional Programming
                            June 8-10, 2016
                  University of Maryland, College Park

                          http://tfp2016.org/

The symposium on Trends in Functional Programming (TFP) is an
international forum for researchers with interests in all aspects of
functional programming, taking a broad view of current and future
trends in the area. It aspires to be a lively environment for
presenting the latest research results, and other contributions (see
below). Authors of draft papers will be invited to submit revised
papers based on the feedback receive at the symposium.  A
post-symposium refereeing process will then select a subset of these
articles for formal publication.

TFP 2016 will be the main event of a pair of functional programming
events. TFP 2016 will be accompanied by the International Workshop on
Trends in Functional Programming in Education (TFPIE), which will take
place on June 7nd.

== INVITED SPEAKERS ==

TFP 2016 is pleased to announce keynote talks by the following two

Re: [ANN] New egg: color - a port of Aubrey Jaffer's SLIB color module

This is awesome! I was just about to play with some colour related stuff and I was feeling sad that I didn't have easy access to different colour spaces. I'm going to use this right now!

Thanks, Erik!

Thanks, Erik!

I've added the release-info to the egg locations, this egg should be
installable in an hour or so.

Cheers,
Peter

Variable Capture in message-digest

Hi,

I've been using the message-digest egg and have happened upon an
unfortunate scenario.

Here is my minimal test case:

-----
(use message-digest sha2)

(define (string->blob string)
 (abort "no way"))

(define digest (initialize-message-digest (sha256-primitive)))

(assert (message-digest? digest))

(message-digest-update-object  digest "x")
(pp (finalize-message-digest digest 'blob))
-----

This aborts with "no way" during the call to message-digest-update-object.

message-digest is expecting to get string->blob from the library
(http://api.call-cc.org/doc/library/string-%3Eblob ) but I'm reusing
that name in my program for something else.

Even tho' I define my string->blob after I (use message-digest), it
seems to affect the binding in the message-digest code.

Is this expected behaviour?

I'm using CHICKEN 4.9.0rc1 and it happens in both interpreted and
complied code.

Regards,
 <at> ndy

Patch for udp egg on mingw32

Hello,

I had problems compiling the udp egg in Windows using mingw32 and came
up with the following patch to fix it:

> # include <winsock2.h>

libotr bindings (Off-the-Record)

Hi.

Does anybody know (partial) FFI bindings for libotr
(Off-the-Record Messaging, https://otr.cypherpunks.ca/ )?

(I know that there is a native Scheme implementation of OTR,
but it relies on R6RS features.)

Ciao

Chicken 4.10.0 and 4.10.1 - 'check' fails

Hi,

I installed Ubuntu 16.04 beta, 64-bit edition. I am not able to build
chicken : the make fails during the check. Results appear to be
identical with both 4.10.0 and 4.10.1. The command and the last part
of the output are at the end of this message.

Here is the offending code.

    (print "\nEmbedded NUL bytes in filenames are rejected\n")
    (assert-error (with-output-to-file "embedded\x00null-byte" void))

What is going on?

Why did this work before?

Thanks.

Missing functions in Chicken IUP?

We are trying to create a popup menu for a matrix in IUP and the documentation mentions IupPopup and IupShowXY but I don't see associated functions under IUP. Am I missing something?

Thanks.
