I though cond-expand was compile-time. I guess I was wrong :) Anyway, what I want to do: I have a definition for a C function that only exists if Imlib2 is compiled without X. So, if X is not found, I don't want a binding for that function. I guess this has to be done compile time, since the function doesn't even exist, meaning the (foreign-lambda ...) can't be translated.

Yes, there are a lot of things that should be mentioned there... ;-) I was just thinking about what's happening now in the Python community. A well-known Python developer dumped all of the official documentation into a Wiki / content management system, and the community is busy filling in gaps, and adding new information. I realize that the Python community is a a few orders of magnitude larger than Chicken's, but perhaps opening up the docs for community editing might alleviate the burden from Felix and the core developers?

Actually, Alejandro suggested this already - there is an unofficial manual: http://wiki.freaks-unidos.net/chicken%20scheme%20manual Now, I have absolutely no problem with this. There is just one catch: I don't want to maintain two versions of the manual, and we definitely need something that can be installed locally. Personally, I would suggest that we use http://galinha.ucpel.tche.br/coop, since it's internal format can be converted relatively easily to/from other formats. What we need is a texi generator.

Re: [Chicken-users] Debugging -- truncating the call-history report?
On 5/26/06, Graham Fawcett [EMAIL PROTECTED] wrote: First, let me ask the short question: when an uncaught exception occurs, is there a way to prevent exception-handler code from appearing in the call-history report? What you can do is the following: put the code that prints the exception in a separate file, compile it with -d0 (so that no debug-output appears). The invocation can be wrapped in a ##core#app form (which is the same as a procedure-call, but unsafe, and it doesn't generate a trace-info entry).

Right now I'm using 'long' (which, I know, is just 32 bits) and filling my code with casts. Perhaps an int64 foreign-type specifier should be defined? As a foreign-type specifier, adding int64_t shouldn't be too hard. IIRC, M$ calls them __int64 (is that correct?)

[Chicken-users] egg index on coop
Hi! I have changed the egg-upload script to add an entry to the following page: http://galinha.ucpel.tche.br/coop?page=egg%20index It's still a bit raw, but it makes it easier to keep up to date with egg-changes (modifications here will appear in the coop RSS feed). This also demonstrates the HTTP API of coop, which is documented here: http://galinha.ucpel.tche.br/coop?page=coop%20API So, if you someone interested in pushing statistics, or other machine-generated info, I'd be delighted if this feature would be used.

[Chicken-users] chicken gui repl
Hello! Kon suggested a somewhat more user-friendly mac-like addition to the OS X binary release, and I thought it would be nice to have some sort of GUI repl that could be installed along with the binaries (and provided with the source release too, of course). So I dug out my mostly unfinished and rather clunky code, which I provide here in the hope that someone with more knowledge of OS X things might pick it up: http://www.call-with-current-continuation.org/chicken-app.dmg It's really pretty bad: evaluation can't be interrupted (suggestion: eval code in each document in a different thread and somehow do some CFRunLoop funkyness to check for an interrupt key-combination), there is no online help (opening Safari on chicken.html should do) and handling input from stdin is not supported (since the current selection is eval'd, so there is no real stdin). Moreover it doesn't use the objc egg, which removes the dependency on objc and libffi, but it might be prefereable to use the wonderful objc bridge. Anybody interested in taking a look?
