[Chicken-users] ANN new eggs for Amazon S3, SendGrid, and Stripe
All of these are available in the official egg repo and are documented on the wiki. Amazon S3 https://aws.amazon.com/s3/: amazon-s3 Manage buckets, upload files, etc. Has a nice method for dealing with Amazon's wacky authentication system, which could be useful in dealing with other Amazon AWS APIs. SendGrid http://sendgrid.com/: send-grid Make sure your email gets delivered. SendGrid sends your email and handles all of the tricky stuff for you. Stripe https://stripe.com/: striped-zebra Take payments online. Stripe is a super easy way to quickly take credit card payments online (US only currently). They are all just built to what I needed and could be expanded. I welcome any contributions and would be glad to add more where the APIs are lacking, if someone needs it.

Re: [Chicken-users] Question about embedding Chicken scheme
I see Julian, so when you said you were looking for an embedded language
for doing quests that's exactly what you meant... :)
I'm curious how you end up splitting your data structures. Perhaps it's all
in C/C++ and then you access then from Scheme? There's an example of you
might do that, if you haven't found out already:
http://wiki.call-cc.org/Wrapping%20simple%20c%20structs
You can also use chicken-bind http://wiki.call-cc.org/eggref/4/bind to
familiarize yourself with foreign-lambda and friends. Chicken-bind has
almost a complete C/C++ parser and can produce foreign-lambdas:
$ echo struct player { int level, health; } | chicken-bind - -o -
;;; GENERATED BY CHICKEN-BIND FROM -
(begin
(define player-level
(foreign-lambda*
integer
(((c-pointer (struct player)) s))
return(s-level);))
(define player-health
(foreign-lambda*
integer
(((c-pointer (struct player)) s))
return(s-health);))
(define make-player
(foreign-lambda*
(c-pointer (struct player))
((integer level) (integer health))
struct player *tmp_ = (struct player *)C_malloc(sizeof(struct
player));\ntmp_-level = level;\ntmp_-health =
health;\nreturn(tmp_);;\n)))
;;; END OF FILE
If you don't have it already, you can do `chicken-install bind` and play
around. Note that `make-player` above leaks memory.
Best of luck!

Are you planning on using any established game-engines or libraries?
What will probably become very interesting is where your C++-code ends
and where your Scheme begins.
Hi Kristian,
The game is currently pure C and C++. As for libraries, I currently use
xerces (XML), curses (UI), Google Test, and boost/stl. The game itself is
currently in a playable state - the player can win or lose, there's a
generated world to explore, etc., though it's currently pretty bare.
My plan is to start with reasonably small scope, and use Scheme for the
quest logic. I'd like to have a number of optional side quests beyond the
basic roguelike dive to the bottom of the dungeon. I could do this in
C++, but I see an opportunity to work in my favourite programming language,
so I'm going to take it. :)
So I have a crazy idea, how about writing all of it in Scheme? So
instead of exposing a function to add a message to the UI, you can
expose functions to draw the UI, and do your game in Scheme. Then as
you move along and things settle, you can port the slow/critical parts
to faster C-code if you need to. Just a thought. There are several eggs
http://wiki.call-cc.org/**chicken-projects/egg-index-4.**html#graphicshttp://wiki.call-cc.org/chicken-projects/egg-index-4.html#graphics
for
graphics available that might suit your drawing needs, like cairo or
opengl.
Much too late for that, I'm afraid! The game itself is currently just
under 2 MB of code, resource strings, and configuration details. I'm quite
happy with its current state. I'd love to try Scheme as the main language
for a game, but this project's much too far in for that.
Julian

You're welcome. :) Also, I just noticed that Stripe is now available in Canada as well. If you are in Canada or the US and want to take credit card payments or handle recurring payments, I highly highly recommend Stripe. No need for a merchant account, gateway setup, or storing of any sensitive information. Once I built the api it only took a few minutes for me to sign up, integrate it into my site, and start processing cards.

The Stripe card processing page can be found here: https://a.keeptherecords.com/sign-up/payment/basic. The homepage is http://keeptherecords.com, which is wordpress. The app, written in chicken scheme, is http://a.keeptherecords.com. (goto /demo if you want to check it out).

Re: [Chicken-users] Msgpack implementation for scheme (and some questions)
Hi Hugo, Msgpack seems like an interesting project indeed. Thanks for making an egg for it! I'm quite a newbie myself, but I noticed the coops egg includes the module implementation directlyhttp://bugs.call-cc.org/browser/release/4/coops/trunk/coops-module.scm, so you don't have to declare two modules. Maybe that's easier in your case too? I also noticed you're using (let () ...). Is there a reason you're not simply using (begin ...)? I've been poking around the msgpack-repositories, they support a lot of languages! It's real neat that Chicken Scheme now joins in on the fun too. So, looking at the node.js porthttps://github.com/msgpack/msgpack-node/tree/master/deps/msgpack, it seems like they've created js-bindings to the official C library. Perhaps this might be suitable for Chicken Scheme too? From what I can tell, you are reimplementing most of the functionality from scratch, is that correct? Great work, great piece of software to keep handy! K.

Unfortunately, machine floating point formats are complicated, so any related code will be complicated as well. I don't know much about the msgpack protocol, but if representing floating-point numbers as strings is an option, I encourage you to look at fpio ( http://wiki.call-cc.org/eggref/4/fpio ), a BSD-licensed egg for converting floating point numbers to strings and vice versa. endian-blob includes code from GDB, so it cannot be relicensed without approval from the GNU project. Ivan On Tue, Jan 29, 2013 at 5:53 AM, Hugo Arregui hugo.arre...@gmail.comwrote: Hi, Recently I wrote an implementation of msgpack[1], which can be found here[2]. This is my first full project in scheme, so I would appreciate any feedback (please, be destructive). A couple of points already has been mentioned: - Macros to reduce redundancy (I'm reading about them, so I'm expecting to fix this soon). - A non technical but important thing: I'm using endian-blob egg, which is licensed as gpl and it's incompatible with the project license, which is bsd. But, beside that, I have a few questions: 1) To avoid the creation of very heavy structures in tests, i'm using a kind of mock[3], which overrides some procedures, and restores it later. Is this the right way to do it?. In fact, in the egg branch I tried to pack the project as an egg and I think this hack is not working. 2) To access the procedures mentioned in (1), i'm using two modules: msgpack-imple which contains the whole project and it's used for the tests, and msgpack which import msgpack-imple and expose the real interface. Again, is this the right way to do it? 3) To read/write float/double numbers (in ieee754) i'm using endian-blob egg (here[4]), it's there any alternative without implementing the full float/double-binary logic (which seems quite complicated)?
