We had already been discussing it earlier today in #chicken. I had another look at the code but I can't really find any obvious inefficiencies. It is indeed a bit faster with CHICKEN 5, but not by much. Of course, Guile is cheating by using GMP. If I compare it to another Scheme which has its own bignum implementation like Gauche, we perform about the same. It's interesting that sbcl is doing so well. Maybe I'm overlooking something seemingly minor but important?

Thanks for posting that; I hadn't looked at the sbcl implementation of the pi-digits benchmark, but indeed that page says Pi digits on the benchmarks game is currently a bunch of calls to GMP. This would *really* be cheating in my opinion, as it's not testing the language implementation but using nonstandard extensions that replace stuff that's already part of the core. I had just assumed it would be using the sbcl native implementation (which indeed is pretty damn good and almost 100% pure Lisp code). In fact, there are two implementations, one of which uses native operations. It is still faster than CHICKEN and very close to Guile/GMP: http://benchmarksgame.alioth.debian.org/u32/program.php?test=pidigitslang=sbclid=2#log It does use some type annotations, though.

Different applications will want fast crude random-ish numbers, PRNGs, cryptographic PRNGs, or full quantum randomness, with tradeoffs for speed and quality. Since that's so, I'd rather require programmers to make the choice up front rather than fall back on some dubious OS version that does who-knows-what. Not all applications require cryptographically secure real random number generators. In fact, I'd argue that most random usage is not for that sort of thing. It will be used in tutorials, or in games for a purpose such as selecting between several available sounds. Or procedural generation if it doesn't totally suck. If you *are* writing something that really requires a better quality pseudorandom generator, odds are that you will have to import one anyway. I have no idea of what rand() uses internally, and much less what is Chicken is actually calling on Win32. So one thing that could be of value is not relying on the OS implementation and instead providing our own (Mersenne Twister?). This would remove a core dependency and guarantee consistency when running on all operating systems. Even if it is consistently crappy(which MT doesn't appear to be, even if it should not be used for crypto). That would be preferable, so you'd deal with it in the beginning, instead of when porting to another OS, when you've already forgotten all about the random generator. For reference: (random N) http://api.call-cc.org/doc/extras#def:random procedure Returns a pseudo-random integer in [0, N-1]. N is an integer. On Windows, N and the random value are exact integer. *Warning*: This procedure uses *rand(3)* internally and exhibits its deficiencies, including low quality pseudo-randomness: - On Windows and Solaris, only 32768 unique random values can be generated in the range [0, N-1]. If N = 32768, there will be gaps in the result set. - On Mac OS X, Windows and some other platforms, little variance in output is seen with nearby seeds. Since the random generator is seeded with current-seconds at startup, new processes may see similar or identical random sequences for up to a minute. - On Linux, *rand(3)* is an alias to *random(3)*, which provides output of reasonable quality. — Stephen ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users

For example: ... Sure, we can do that! I didn't mention it so far as this property is implicit with how CHICKEN core strings work. I think you are assuming too much background knowledge. Maybe in a perfect world, everybody would get a CS degree, then learn all the fundamentals of Scheme, then master the Chicken core, then start working with extensions and building practical software ... but of course that's often not how it works in reality. And in my opinion - as someone with no formal education in the field, but who came to Scheme with a few years of practical experience in other languages - I think Scheme in general, and any given implementation, has a really steep learning curve. The documentation is good in that almost everything you need to know is covered somewhere, but it can also be really hard to find the information due to the extreme modularity and very bazaar-like culture of Scheme - docs are split up between r*rs and an implementation manual and extension docs written by different people following very different conventions. Additionally - and this is not anyone's fault in particular, more a side-effect of the small community working on Chicken - since the documentation as a whole is not rigorously maintained, contradictions inevitably creep in, and there are often several ways to do the same or similar things, with no indication of which is best or recommended. Sorry to rant ... I'm rather passionate about documentation. Must be my Python background ;-) I believe I complained about this once. But I've since stopped complaining, because I had no useful ideas on how to improve things. If you already know what you need, things like Chickadee are awesome. If you are trying to figure out a strange behavior, I've since learned to go back to the R5RS docs and, if not there, look up 'deviations from the standard'. If not there, I'll stumble through the documentation like a cockroach on meth. Sometimes I manage to find useful information, sometimes I don't. I'd never find out about CHICKEN core string behavior, for instance. One idea I came up, but never implemented, was to record a list of 'documentation cache misses'. Would go like this: every time I failed to find something in the documentation, I'd record what it was. If I really couldn't find it, I'd ask around here or on #chicken. If noone could find it, then I'd mark it to be inserted somewhere (or updated). It's not quite that simple: Characters may be encoded in many ways, UTF-8 is far from the only widely used one and not ideal in all cases, e.g. the algorithmic complexity of some operations on UTF-8 encoded strings is objectively worse than those on UTF-32 encoded strings. And it will remain so even till the year 2050. Not guarantees on what happens after that, though! I'm certainly aware of different encodings - I started programming when I lived in Japan in the 90s, before Unicode 1.0 was finalized, and there were 3 major encodings in common use just for Japanese. But there is such a thing as 'reasonable defaults' - if you can't support all the encodings, what is more interoperable than UTF-8? Nothing that I'm aware of. Making it the default can hurt some japanese users, I'm told, because encoding conversion between ( - forgot what the encoding was) and UTF-8 can be lossy. Many implementations use UTF-16 internally(Win32 API, Java). Maybe the are up to something, performance-wise. I'm of the opinion (shared by many I18n experts, if I'm not mistaken) that a high-level language in the 21st century should have in its core a rock-solid character abstraction that is never, ever conflated with a byte. The character abstraction actually is rock-solid even in CHICKEN 4 already: A character object represents a Unicode codepoint in an encoding independent way. Okay, but that isn't reflected very well in the core API. Here's what bugs me about the laissez-faire approach to strings

Embedding GLSL shaders into your programs is now as easy as writing S-expressions in a Scheme file. The compilation from a glls definition to a GLSL shader happens at compile-time, so using glls has no run-time cost (aside from having it loaded into memory). Using glls gives your Scheme program knowledge about your shaders, so shader and program compilation as well as attribute and uniform location retrieval is provided automatically. If you're familiar with Varjo (a Common Lisp project), glls performs a similar task but with a more limited scope. While Varjo performs type-checking to validate its shaders, glls is a very literal compiler: you get what you write – even if you write something wrong. Errors at the GLSL level are therefore caught during GLSL compilation rather than during glls-GLSL compilation. If I may be so bold: The best has yet to come for glls. While defining your shaders in Scheme is convenient, the true power of this comes from taking advantage of what your Scheme program then knows about the shaders. Future work on glls will see automatic compilation of rendering functions for each pipeline, as well as tools for dynamic re-loading of pipelines for all your REPL-based shader hacking sessions. If you’re interested, check out the source: https://github.com/AlexCharlton/glls And the docs: https://wiki.call-cc.org/eggref/4/glls And if someone could add this to the egg list, I would be most appreciative. https://raw.githubusercontent.com/AlexCharlton/glls/master/glls.release-info Thanks!

Re: [Chicken-users] Chicken Scheme for mobile devices?
Yes, please. I've been toying with this idea for quite a while now. Chicken already works without modification on iOS. However, since you cannot link to third party libraries dynamically, you'd have to compile two versions (x86 one for the simulator, ARM version for the device) and statically link to the correct version. What I have done previously (successfully), was to grab the generated C Chicken (runtime.c, srfi-1.c, ports.c, etc) and added to the XCode project. Then, I compiled my program and asked csc to just dump the .c files. I then added it to the project as well. Also added a Makefile so that they would get recompiled as necessary. That worked, I was even able to open a remote REPL and make changes and have them displayed in the device (the OpenGLES drawing code was written in Scheme). The advantage of this approach was that one doesn't need to care what the target device is. However, it is too 'hackish' for my tastes. Not to mention that it would be a pain to add eggs. But it proved that Chicken works fine on iOS. Since one can call Scheme functions from C, it is trivial to do so using Objective-C. The other way around should be possible too, but I haven't poked too much into Objective-C's internals yet. If all else fails, we could always write 'foreign code'. Building a cross compiler (and using the correct one in the iOS build system) is rather tedious, as is statically linking the correct eggs. If we had a tool to generate a 'template' project and maintain it, we'd have a winner. Actually building it could be accomplished by xcodebuild, as long as we add a build step that calls csc. I'm talking about iOS since that's what I am used to, but this could be even better under, say, Android. Anyone knows what the state of the NDK nowadays? Would we be able to create apps in mostly Scheme? -- Stephen *Kids these days.* *Whatever happened to hard work?* -- Joel Spolsky, The perils of javaschools On Tue, Nov 13, 2012 at 4:09 PM, Andrew Pennebaker andrew.penneba...@gmail.com wrote: I see the beginnings of a Chicken Scheme port for Android: https://github.com/kristianlm/chicken-android I'd like to see ports for other mobile platforms (iOS, Windows Phone, Windows Surface).

[Chicken-users] OCD Egg
Hello guys, I know it's been a while, I've been quite busy the last few months. Unfortunatly, that's not Chicken-related :( However, I want to redeem myself. Therefore, I am requesting comments on a simple egg I've made. It is not yet what you would consider stable, but I am already using it for some time now to develop my projects. For those who know them, it is similar to 'autotest' or 'guard'. That is, it scans the filesystem and runs a command whenever the files it is interested in have changed. This is useful specially for those who like to code using tests. Its default behaviour is to scan for .scm files in the current directory and, whenever any files have changed their timestamps, it tries to run a Makefile. You can customize it somewhat with a .ocdrc file, in order to filter a different file set, or run a different command when they have changed. You can force a run by hitting Control+C, or abort it hitting Control+C twice. It is currently missing support for inotify (or fsevent under OSX), so it needs to poll the filesystem (by default, every two seconds). This might be a problem for large projects, but so far this has not bothered me much. So, what do you guys think? I intend to improve it some more if at least one more person finds it useful :) This is the repository: https://github.com/outworlder/OCD -- Stephen *Kids these days.* *Whatever happened to hard work?* -- Joel Spolsky, The perils of javaschools ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users

Re: [Chicken-users] ANN: Lowdown, a pure Chicken Markdown parser
On Sun, Aug 5, 2012 at 2:27 PM, Moritz Heidkamp mor...@twoticketsplease.dewrote: Fellow Chickeneers, yesterday I released the first version of Lowdown, a Markdown parser written in pure Chicken Scheme. The only other Markdown parser egg we had so far, discount, requires the corresponding C library and can only read and emit strings. Lowdown doesn't have any foreign dependencies, can read from strings or input ports (well, any lazy-seq of chars, really) and emits SXML. It passes all 22 tests of MarkdownTest version 1.0.3. I also started implementing a very basic extension API but that's not ready for public consumption, yet. For more information, check the documentation at the usual place: http://wiki.call-cc.org/eggref/4/lowdown Hope it's useful to anyone! Cool! I must apologize, btw. I was written something that required a Markdown parser and I didn't feel like going on this huge detour to write a Markdown parser in Scheme, so I just used the Discount library and that's it. And reading and emitting strings is actually a nicer interface than what you'd normally write with Discount - took me a while to backtrack and redo it, it was going to be something much more complex to begin with.

If this is how you feel about the egg, I think it's probably a good idea to change its category to deprecated, and put a note on the wiki page pointing people to the lowdown egg. This provides some transparency about the egg's status, and guides people's expectations. I don't hate it. However, since we have a pure Chicken version, I see no reason to have it around.

[Chicken-users] Coops print-object, error handling and flaming koalas
Today I hit a problem with some trivial code I wrote using Coops that I just couldn't figure out. The relevant code is here: http://paste.call-cc.org/paste?id=d09b2c1438a7f063c07cd089fb3e74c68d0b2804 Yeah, I forgot to add the port argument. In any case, Coops' error message is misleading: #no print-method defined for: #coops instance of `color' There is a method alright, it's just crashing :) Now, This is how coops handles the situation: (define-record-printer (coops-instance obj out) (handle-exceptions ex (begin (display #no print-method defined for: out) (default-print-method obj out) (display out)) (print-object obj out) ) ) It will display the same error message regardless of the condition. So let's modify it to see what it was: (define-record-printer (coops-instance obj out) (handle-exceptions ex (begin (display ((condition-property-accessor 'exn 'message))) ; (display #no print-method defined for: out) (default-print-method obj out) (display out)) (print-object obj out) ) ) The actual error is thus: #Error in printer of record type `coops-instance': bad argument count - received 0 but expected 1 which is an (exn arity), in my code. As pointed out by sjaaman, it should only catch the dispatch error. I could create a patch to do that, but I am not confortable enough with coops' code at this point and I am sure the error handling could be improved in ways I can't even see yet..

Re: [Chicken-users] [wish list] chicken-install: show available eggs, upgrade all installed eggs?

It would be good to be able to show available eggs when installing an egg, such that user can grep and find wanted eggs quickly without having to browse at http://wiki.call-cc.org/chicken-projects/egg- index-4.html. Simply a text dump of that html page would help much. That is possible, but would require a regularly updated master document somewhere on our server. Henrietta already provides a list of eggs to chicken-install. I suppose that could be used, if we don't care about showing egg descriptions in such a list. The other feature is being able to upgrade all installed eggs after, for instance, upgrading chicken. Then i don't have to reinstall each missing one by one, desperately. That has been requested repeatedly in the past, but I'm sceptical. Bulk updates like that make it extremely easy to break everything, unless you have a very rigid control over the stability of the currently available extensions. The egg repository is actually pretty good in that regard, but still, broken eggs and broken dependencies slip in from time to time. We are quick to fix those, but something like a bulk update could easily result in broken installations. For example, I may have several applications that use one or the other installed egg. Those eggs may be out of date, but I'm more interested in having my system running, so when I install new extensions, chicken-install will warn me when an egg requires higher versions and I have the choice to think twice about whether I want to do that or not. But only if you already know which versions you are supposed to be using. For deployed code, I guess you could take the list from a running server, manually. For code sitting in a repository, it doesn't work like that. Even when you do know the versions, it could get tedious.

As far as I know, nobody uses automatic extraction of comments from code. And that's a shame. Why? Almost all the extracted documentation I've seen is of shitty quality; people tend to use automatic extraction of docs as an excuse not to write proper documentation. As opposed to not writing it at all, or having it get out of sync with the code, as they live in different places. Also, it is trivial to extract documentation for, say, an older egg version. Which is in sync with the code, by default. When you have documentation in the code, it goes wherever that code goes. Also, writing documentation by hand forces one to think about writing it in a way that it can be read from beginning to end and have it make sense. But that's usually done after the code has been written, as an afterthought. Having documentation on a wiki means people can add notes about and rewrite sections they found difficult or hard to understand, thereby increasing overall quality. Notes can be added no matter how the documentation is generated. As for rewriting sections, I agree with you - it is easier in a wiki. It would be helpful to know how often that happens in practice, though. One can make the argument that it would be *easier* to document the code because you are looking at it, it is sitting right next to the docs. If you are reading it in the source you can even spot the fact that, say, a function's arguments are documented wrong, because you can see it right there. Finally, when the inline documentation *is* done really well, you end up with a lot of documentation getting in the way when you're trying to read the code. That is also true. See, for instance, ActiveRecord. It has benefits too - you can see the documentation right next to the section you are editing or trying to understand and breaks up code sections visually (when done well). I have stopped complaining about the lack of docstrings when chicken-doc (and chickadee) was created. It is not an ideal solution (from my point of view), but it mostly solves the problem of retrieving the documentation for chicken and eggs in the repository. However, I still think that it could be useful. If not for Core and Eggs, then perhaps for our own Scheme projects.

[Chicken-users] Trouble with FFI and 64 bit machines
Hi guys, As some of you might be aware, I am creating bindings for the Discount (http://www.pell.portland.or.us/~orc/Code/discount/) library. However, I have run into a problem. When testing on my OSX (Snow Leopard) machine with a 64 bit chicken, I get a segfault. After some debugging (and Ventonegro's help), I've narrowed it down to the following definition: (define mkd_in (foreign-lambda c-pointer mkd_in c-pointer int)) The function being bound is MMIOT* mkd_in(FILE *f, int flags) (where MMIOT is defined as void by the header file), which returns a pointer that is fed to the 'markdown' function for processing and blows up the first time it is dereferenced. I get the following compilation warning, which is likely the source of the corrupt pointer: csc -c testcase.scm testcase.c: In function 'stub3': testcase.c:31: warning: cast to pointer from integer of different size Even though I get the same warnings under Ubuntu 64, it runs fine. To reproduce the warning: Just create a file containing the above foreign-lambda and compile it with csc -c.

Adding (foreign-declare void *mkd_in(void *, int);) in front of that code causes it to compile without warnings. Perhaps you should figure out whether the header file is being included properly. Maybe you can temporarily put a #error hi just before the function's prototype in the header file, so you can see if it's not skipping the prototype due to a #ifdef or something equally silly. The reason was something even more silly: I was not including the header file at all. Turning on -Wall reveals that yes, the prototype was missing. GCC is appeased now.

SQLite3 is a great, lightweight database, but I have hesitated to use it in Chicken applications because it's not guaranteed to be installed or recent enough on a user's machine -- especially if they're on Windows or OS X. Installing it can be an annoying extra step for your users. To that end, I've updated the sql-de-lite egg to include an integrated SQLite3 library, currently 3.7.0.1. At installation time, the egg will auto-detect whether your system library is present and recent enough. If so, it links against your system library; if not, it links against the built-in library. It's also possible to override the auto-detection if desired. The goal is to allow you to just depend on sql-de-lite in your application and not worry about whether the library is installed or too old. SQLite3 is a great replacement for ad-hoc file formats and, even if you are not a fan of SQL, the underlying database tech is top-notch.

Graphical tools (like Gnome's proxy settings) will even set it automatically. The -proxy option in chicken-install is handy.

Some possible improvements: * Add support for proxy authentication. The proxy at work actually requires this, but I have setup a local proxy to forward the requests, so that apps that don't support it will work.

Could someone of the fine people on this list point me to some hints in the docs or explain here why there are those two separate things and what the differences are? I was once puzzled by this, too, but I think I have figured it out now. The other experts on this list can correct me if I make a mistake. The short summary: modules work on syntax, controlling the mapping between symbols and bindings at top-level. Units work at runtime, ensuring that code is initialized and top-level statements are executed in the correct order. Here's the long explanation: * modules: a syntactic construct that associates names (symbols) with bindings. In Chicken, all bindings are top-level; a module lets you access those top-level bindings with different names (or even hide---effectively---some bindings because there is no name existing inside the module that refers to them). Purely syntax. Modules are very important for macros, because free symbols in the output of a hygenic macro should refer to bindings according to the mapping in place *when the macro was defined*, not the binding in place when the macro is used. * units: a way to designate some code as intended to be included in a larger library or program. The issue that units try to solve is that, in general, top-level forms in Scheme have side-effects. Consider: (define (foo x) (+ x 1)) When this is executed, the global namespace is extended with a binding for 'foo that refers to a function of a single argument that adds one to the argument. This behind-the-scenes stuff must happen before any code runs that uses foo, or things break. Units help ensure this. The (declare (unit foo)) declaration states that the code in this file is designated by the name foo. The (declare (uses foo)) declaration says the following code uses definitions from foo, and ensures that all the behind-the-scenes stuff that needs to happen in the foo unit happens before executing any statements in the current file. In other words, units are a way of managing separate compilation of code. Put some code into a unit and compile it. Then using it in another bit of code will make sure that the code in the unit runs before any code in the using file (including all the behind-the-scenes stuff that needs to happen to initialize the bindings in the unit, etc). Does this help explain the difference?

What is the purpose of uri-generic anyway? It is an implementation of RFC 3986, which is much more broadly applicable than just in web URIs. For example, URNs like urn:ietf:rfc:3986 are also URIs, but not URI-commons. They have no authority (user/pass/hostname/port combination), and no query string either, only a path. Some other schemes *do* have query strings, but not x-www-form-urlencoded ones. The uri-generic egg is intended for handling the full generality of all these types of URIs, whereas uri-common is intended for the specific common subset of URIs which are usually used on the web, to indicate a host, port and path indicating a resource on that host, with optionally an x-www-form-urlencoded query to pass to that resource for further processing. uri-common adds a few extra conveniences like more complete path decoding (all percent-encoded bits are fully decoded) because it knows this is allowed since the path's components are separated by slashes but have no additional separators with special meaning inside. Other schemes can't be handled this way. For example, the URN scheme mentioned above has a colon (:) which has special meaning, so %3A could not be decoded into : until after the parts are separated; urn:foo%3Abar:qux would be decoded to foo:bar:qux, and hence it would be indistinguishable from urn:foo:bar:qux. So, to summarize: you would never need or use uri-generic unless you're writing a more specific URI parser for other schemes than the common ones.

The behavior is slightly different and it seems that I'm hitting another bug: The following installed extensions are outdated, because `intarweb' requires later versions: uri-common (??? - 0.2) (uri-common is currently not installed).
