Re: [Chicken-users] (seemingly) random disconnects of zmq sockets
Thanks for your answer Kristian! I tried a patch I got from Mortiz, compiled against the zeromq package in the ArchLinux tree (3.2 I believe) and saw the same problems as well, but I'll give this branch a spin later today and will create a sample program to reproduce the error.

Perhaps you could make a smaller example where this bug is reproducable? There is a branch where we're trying to update the bindings to work against zmq version 3.2: https://bitbucket.org/DerGuteMoritz/zmq/commits/branch/3.2 In this version, the glue-code has been simplified quite a lot and perhaps that solves your problem. You could try against this zmq egg-version and let us know if that helps! K.

[Chicken-users] Medea Egg: nested lists/pairs
Hi, I'm using the medea egg, installed via chicken-install, and I'm encountering a problem unparsing lists that contain pairs with more list/pairs. To my understanding of the source code, write-json should just call itself on the cdr of the pair, but I get an error: #;2 #;2 (write-json '((one . 1) (two . '((three . 3) (four . 4) Error: (car) bad argument type: quote Call history: syntax (write-json (quote ((one . 1) (two quote ((three . 3) (four . 4)) syntax (quote ((one . 1) (two quote ((three . 3) (four . 4) syntax (##core#quote ((one . 1) (two quote ((three . 3) (four . 4) eval (write-json (quote ((one . 1) (two quote ((three . 3) (four . 4)) Do I need to provide my own unparser in order to be able to create nested objects or is there a different approach I have overlooked?

(quote ((three . 3) (four . 4) As you can see, that is not what you intended. The inner quote gets quoted, too. So just leave it off and it should work as expected!

[Chicken-users] Parsing EMail
Hi List, I'm relatively new to chicken and this list, so bear with me :) My aim is to parse EMails (for using with procmail, for instance) but I'm a little stuck/confused by my options. I've been playing with hato-mime.scm (hg cloned from google source project), and I also looked at internet-message, but without trying to sound like I'm complaining, the docs are somewhat meager for the beginner that I definitely am :) So my question is: could somebody point me to some example code for either one or the other library that can get me started? I basicall would like to be able to parse message into they parts (different bodies for content-types, attachments..) and play with them in chicken. Thanks in advance!

Cool, thanks, thats quite helpful! Which version did you clone? http://code.google.com/r/datenhobel-hato-egg-update/ that one :) ...has some updates which allow it to compile for later Chickens but not all the modules are included. A few weeks back I got some help with getting this install by some friendly schemers on the IRC :) So my question is: could somebody point me to some example code for either one or the other library that can get me started? I basicall would like to be able to parse message into they parts (different bodies for content-types, attachments..) and play with them in chicken. I've not used Hato before but I've taken a quick look at http://code.google.com/r/datenhobel-hato-egg-update/source/browse/hato-mime.scm ...and it strikes me that calling (mime-message-sxml) and passing it a message on the current-input-port should get you a data structure that you can explore. Ah I overlooked this, thank you. It seems It does indeed just do what I need :) Alternatively, there is this example in the source: http://code.google.com/r/datenhobel-hato-egg-update/source/browse/examples/user.filter I don't understand though: is the parsing explicitly invoked, or are these rules matched against an already parsed message?
