I like the mental state programming in Forth puts you in. Focusing on thinking about the problem first, then breaking it down into stack shuffling operations. This can be a deeply rewarding mental exercise. Chuck Moore is a brilliant person. I gave up on Forth after I realized the language seemed to...

I'm not sure if it's possible either, unfortunately. I noticed something that could be a problem, though: the use of sys-info within my-sys-info after you redefine it to be my-sys-info . It's probably better to think of these kinds of macros as rewrite macros. I use them mostly for writing DSLs. The...

Hi cormullion! Defining f as global hides the fact that f is still defined in MAIN . You can see this more clearly in the following: > (define (f) (context)) (lambda () (context)) > (f) MAIN > (context 'Fred) Fred Fred> (MAIN:f) MAIN Fred> _ In order to refer to f without the global definition, we m...

In the newLISP manual, under "1. Syntax on symbol variables and numbers" in the "Symbols for variable names" section, number four states: A symbol name starting with [ (left square bracket) and ending with ] (right square bracket) may contain any character except the right square bracket. I had to l...

It looks like Seth used PCRE 5, which has "named groups," thus allowing for recursive matching. This feature does not appear to be in the regex library TextMate currently uses.

Hi cormullion!

TextMate's parenthesis balancing has always been a weak spot. Since TextMate uses regular expressions to do the parsing, it's extremely difficult to balance a set of symbols to an arbitrary nesting depth.

And I agree with you on the colo(u)r schemes! :-)

Congratulations, johnu, on such a monumental accomplishment! This translation is very important for newLISP's wider adoption. Thank you, sincerely. About the verb in the first example, cormullion's right. Although, technically, the full verb is "will parallelize." It the second example, the second s...

It's maybe to early to say that it totaly won me, but it seems that's on the way. It took me a while to fully appreciate newLISP, and I almost gave up twice. It's deceptively simple. Sometimes, it seems, too simple. If you've been habituated to complexity, it can take some time to see the straightf...

. . . but i'm wondering how much people use it, and what they build in the real world with it. Hi Ormente! Welcome. I hope you find newLISP as rewarding and productive as I have. I'm not a real programmer (I don't even play one on TV), but I've been using newLISP exclusively for four years now, and...

Here's one more way to set variables:
Of course, define cannot be used to do multiple assignments. I think Lutz said this form was designed for Scheme programmers to feel more at home.

Michael, I've never used setf like that. I don't normally use setf for variable assignment either, but the comment from Greg (itistoday) sparked the new test. I was really surprised by the results. I assumed setf was slower since it's used, as you quote: when setting list or array references I wond...

setf is faster than set : (define (test-setf-once) (setf a 1 b 2 c 3 d 4 e 5 f 6 g 7)) (define (test-setf-multiple) (setf a 1) (setf b 2) (setf c 3) (setf d 4) (setf e 5) (setf f 6) (setf g 7) ) (println (time (test-setf-once) 1000000)) ;=> 372.934 (println (time (test-setf-multiple) 1000000)) ;=> ...

And a single call to set is faster, too: (define (test-once) (set 'a 1 'b 2 'c 3 'd 4 'e 5 'f 6 'g 7)) (define (test-multiple) (set 'a 1) (set 'b 2) (set 'c 3) (set 'd 4) (set 'e 5) (set 'f 6) (set 'g 7) ) (time (test-once) 1000000) ;=> 447.211 (time (test-multiple) 1000000) ;=> 609.038 m i c h a e l

This works: (setq $fn "myfuncname") (context 'test) (set (sym $fn) (lambda (num) (for (i 1 num) (println i ":" $fn) ) )) (context MAIN) (test:myfuncname 5) Since you're defining the function within the test context, sym already creates the symbol there. Hope that helps. m i c h a e l

John McCarthy wrote in the LISP 1.5 programmer’s manual that LISP differs from most programming languages in three ways: The first way is the data. In the LISP language, all data are in the form of symbolic expressions usually referred to as S-expressions. The second important part of the LISP langu...

Congratulations to Greg (itistoday) of Tao Effect for a positive review of his Espionage program in the June issue of Macworld (page 18).

Good show!

It seems the links in the left-hand frame of the manual aren’t working correctly in Chrome. Clicking on a link opens a new window with the non-frame version scrolled to the end of the document. They work fine in Safari and Firefox, however, so it’s probably just a Chrome issue.

How about this?

This does the trick:
I’m sure there’s an even better way, though.

The error Rick pointed out has been fixed and the new video uploaded. Thanks again, Rick!

Rick, wonderful to hear from you! As always, your kind and thoughtful words bring me great encouragement. The club is a certainly a poorer place without your presence. (One small error: at 14:43 you can see that the point given in the constructor and the point reflected by the REPL (constructor) are...

Very aesthetic video! I have seen that Rob Britton had presentation on FOOP few days ago: Thanks, Kazimir! There are a number of meanings for FOOP, some of them quite distasteful ! When I first considered FOOP as a name back in 2006, I found a reference to Functional Object-Oriented Programming in ...

I'm happy (and relieved) to announce the release of "What the FOOP?", a video overview of the current state of FOOP.

All done!

Not sure what you mean here, Lutz. Can you elaborate?

Thanks for another release!
