Re: [Chicken-users] PS-tk documentation missing?
I am the maintainer of PS/Tk. The official version is on SourceForge, and includes the code necessary to run in Chicken; in fact, Chicken was the first Scheme implementation for which PS/Tk was originally developed. I believe Chicken provides a customized version, but am not familiar with the details of how it is loaded or what changes it makes from the official version.

Re: [Chicken-users] Build Failure (maybe infinite recursion) on x86_64 Linux

Thanks for reporting this. If you say infinite recursion, is there anything that indicates an actual recursion? Or does it just hang? Can you invoke the command above with an additional -debug p and show me the output? I have no direct evidence that it was an infinite recursion. It was just a guess by the symptoms, but admittedly I have little knowledge of Chicken's internals. Sorry for the noise on that. The symptoms are that CPU usage increases to max, memory usage increases steadily, and the process appears to hang. Adding -debug p produces no output, even when removing -quiet. When I remove -no-trace and add -debug p it also fails in the same way. But when I remove both -no-trace and -debug p it works. So it fails when -no-trace and/or -debug p is specified, but works OK when neither is specified.

It would be nice to know which one is most likely to be supported in the future or to converge on just one tk interface for Chicken. You don't have the manyargs feature (arm system?), so a generic use of apply with large argument lists may exceed the argument limit. PS/tk is built on the original code developed by Wolf-Dieter Busch (which in turn is based on code by Sven Hartrumpf). PS/tk is newer, but tk is better adapted for chicken. cheers, felix ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
[Chicken-users] utf8-srfi-13 and string-join
Hi, I just found out today that the utf8 version of srfi-13 doesn't have or export string-join. (though the non-utf8 version does) I'll probably roll my own version for my own use until it is added, but I don't know how to write one that is properly utf8-aware, so I don't think it would be worth submitting. I actually can't remember if it was included in chicken before, or maybe in my recent programs that used I was simply using the non utf8 version by coincidence.. Maybe there is a technical performance reason why it isn't included in the utf8 version, or perhaps I'm missing something?

[Chicken-users] setting a callback in xlib
Hello, Xlib has a function 'XSetErrorHandler'. You pass a callback to it to specify the new error handler. Here's the relevant code from 'Xlib.h': -- typedef int (*XErrorHandler) ( Display*/* display */, XErrorEvent*/* error_event */ ); extern XErrorHandler XSetErrorHandler ( XErrorHandler /* handler */ ); -- Here's how I'm defining 'XSetErrorHandler' on the Chicken side: (define XSetErrorHandler (foreign-safe-lambda c-pointer XSetErrorHandler (function int (c-pointer c-pointer And finally, a test error handler: (define-external (xerrorhandler (c-pointer dpy) (c-pointer ev)) int (display Error handler called\n)) If I trigger an X error, I get a pretty wacky error: Error: bad argument count - received 134902918 but expected 2: #() Anywho, do the definitions above look OK?

[Chicken-users] ANN: Chicken 4 box, mailbox, stack, synch, setup-helper
Hi Folks, Some new eggs for Chicken 4. box:2.0.0, mailbox:2.0.0, stack:2.0.0, synch:2.0.0 are updated from the Chicken 3 originals. All are modules. mailbox synch have unchanged APIs. box stack have some changes to the API. synch is still missing a test-suite :-( setup-helper:1.0.0 is kinda like my Chicken 3 setup-header.scm but installed as an include extension; which means while it has setup-info the usage is '(include setup-helper)'. Only for use in Chicken 4 .setup files. The setup-helper test is a successful install of the above ;-) All of these are dependent on the latest chicken/trunk.
