One thing on the TODO list: non-blocking sockets, which would allow internet services to be more reliable and avoid a race condition when doing things the traditional way using net-select/accept on sockets that are bound and listening for incoming connections. Haven't had time to do it myself. One ...

Actually to me co-routines are not a major feature in Lua. One problem is that a procedure which is not "co-routine aware" cannot be turned in to a "co-routine aware" one. If someone provides a GUI library without a single-step gui.run() function (silly example), you are screwed. So if you have a lo...

Let's Rock'n'Troll! I've lurked on comp.lang.forth for a long time. One thing I couldn't understand is why people constantly compared Forth with C, which was pointless in my eyes because they where in whole different categories. It became even more pointless when Lua began to gain traction, because ...

FOOP. The F should be a P. Every time I try to use it for something more object-y than glorified structures, it falls flat on its face (and even as glorified structures, it's not really convenient out-of-the-box). I'd rather use contexts for prototype-based objects. Kind of what the /dev/urandom exa...

I quite agree that Java is becoming less relevant these days. But I disagree that the way to go is the browser. Just like Java, Javascript is cool because it's "already there" and "cross-platform", but it's still poor at making interactive apps. The CSS/HTML/Javascript was never meant to build deskt...

Maybe the OP was talking about the name of the files rather than the content?

Hello,

Doe anyone have bindings for the IUP library?

To me, the major split is between Windows and Linux platforms. That's also true for sockets. You have no choice but to write platform specific code and to hide the differences behind the a common API. As for DSR/DTR, RS is such a mess that one can always stumble upon some hardware that do use that. ...

That's because '(1 2) is a quoted expression, not a list:

int returnneg(void) is a valid prototype.It's actually "more correct" than int returnneg(): the former tells that the function takes no arguments, while the latter can take any number of arguments.

I work with the manual essentially, plus the "code patterns" file. Both of them give a lot of recipes. One thing to note about NewLisp is that its built-in functions library is very rich. And many of these functions can be used in more than one way thanks to the clever use of default parameters. As ...

Maybe that work could be reused for a different thing. I didn't really run into the issue as of yet, but a potential memory management problem may happen with external libraries that return allocated object, and you are responsible for freeing them. It seems there exist no way to "link" with Newlisp...

Debugging and error messages are still a weak point of Newlisp for me. I could make it slightly easier by inserting a call to getDebuggerInput() at the end of printErrorMessage(). At least one can check the value of local variables, arguments, and even those of the callers if names don't overlap. Ca...

Arrays versus Lists The deal is that lists are good at insertion and bad at random access, while arrays suck at insertion and are good at random access (I've measured a 30% difference on random accesses). More often than not, one does a bit of both, so the choice between lists and arrays is not obv...

Node.js is popular because it's javascript. It let "web" developers reuse their knowledge, server-side. Javascript itself is one of the biggest steal in CS history IMHO. The language design is full of WTFs (kind of the opposite image of Newlisp if you ask me), but it is the language of web browsers....

I used (net-receive-from) to make a little UDP proxy under linux. When I ran it under windows, it unexpectedly didn't work.

It seems that under Windows (XP), the address field which is returned is in the form ip-address:port.

Maybe a useful tip: use letex to avoid fiddling manually with self-fields. For instance:

I know this is different from what I initially asked for, but... if you remove lines from 4912 to 4921 (the ones that insert the expansion code), one gets interesting options for forging the replacement expression. Like for instance this improved curry: (macro (curry*) (case (length $args) (2 (letex...

Also, I spotted by chance a misuse of define-macro in the "apply" entry: my-gcd is defined as a macro; but if you try (my-gcd 12 18 (+ 1 2 3)) one gets an error.

Oh, nice!

Do I have to wait 10.5.8 to officially come out or can I grab it right now?

Hello, While programming a little tool that analyses some log file, I've noticed that read-line is a bit slower than one would expect. Looking at its code, it appeared to me reading the stream char-by-char could be the cause. I Modified it to use fgets instead: char * readStreamLine(STREAM * stream,...

May be if you replace (println k) with (println “=====>” k), you can better follow the debug behavior Indeed I thought about this possibilty and did something like that. It seems I didn't put enough dashes in my println. fexprs are functions, so I would argue: the behavior is expected. args should ...

Consider this dumbed-down version of do-until: (module "macro.lsp") (define-macro (DO-UNTIL test B) (do-while (not (eval test)) (eval B))) (macro (DO-UNTIL* T B) (do-while (not T) B)) (println "test 1") (define (foo k) (DO-UNTIL (<= k 0) (begin (println k) (dec k)))) (foo 3) (println "test 2") (defi...

I'd like to use this nice little GUI library: http://enchantia.com/software/graphapp/ The widget set is not as full featured as other libraries but it's good enough for simple user interfaces. Plus it fits in a single 700K DLL and is portable. The problem is that it passes and returns one of its maj...
