Common Lisp is too hard.

I still can't get my head around prefix notation. I heard Scheme is easier though. Seriously, why do practitioners of Lisp-like languages claim it's so good? I honestly cannot see the big deal, it's an old, slow, awkward and overall clunky language to use.

Read SICP, newfag.

How about giving arguments other then "lol read sicp." Explain, what's so good about CLisp/Scheme? If it's so good, why aren't more projects written in it? Today, it's all Java, C++, C, or one of the .NET languages. As far as I know, people only use the Lisp-like languages for small, shell-type tasks / cgi scripts, and even then there are far more suitable languages available (Python, Perl, etc.)

Use Erlang instead. Built-in language features to guarantee high-availability via load-distribution across a cluster. Arguably cooler than Scheme, if I may blaspheme.

>I still can't get my head around prefix notation. I heard Scheme is easier though.
You realize they use the exact same notation, right? And now can you possibly find it hard to grasp? Instead of foo(bar) it's (foo bar).

>>3
Sigh... don't call it CLisp. It's Common Lisp or CL. ComLi may be acceptable. But CLISP is something else.

Some guys in Hungary recently went online with some government data collection software to aid in budget planning.

First link doesn't mention implementation language. Fabrication until further evidence is provided. I bet any money it's implemented in Java.
Also, source for the second one?
In any event, I'm still not convinced lisp-like languages are useful at all.

there's seriously something wrong with you if you look at prefix notation and decide it doesn't make any sense.

See Dan Weinreb's posts on comp.lang.lisp for the first. See c.l.l for the second as well.

(loop ... ) is my favorite thing from programming ever.

Whoever thinks prefix notation is good for expressing math is an idiot. All it does is make writing the fucking parser easier.

Does anyone seriously think prefix notation is better for expressing anything resembling math. All it does is make parsing easier.

Massive amounts of truth in this post

Hello Cyan.

is far superior to it's retarded infix cousin.

>>36
(* 4 73 (+ 5 10 (- 8 8)))

is far superior to its retarded mathematically equivalent cousin.

4 * (5 + ((+8) - 8) + 10) * 73 is a nightmare, btw.

>>37

Why not just write down the answer? Geez.

>>38
Presumably >>36 was thinking (insofar as >>36 is able to think) about the general form of the equation, and just doesn't have the mathematical know-how to use variables instead of literal numbers.

Horrible. Why is this taught to people worldwide in schools? We should all learn some weirdass notation so we can be more eleet.

lol holy shit you fucking faggots

If you just learned lisp yesterday (or you're slow and you've been learning it for 10 years but still think it's the best thing in the world), infix arithmetic is better!
Simply fucking is you idiot.

The reason prefix notation is better is because you have a single uniform representation of code and [u]data[/d], the language is homoiconic.

(= CODE DATA) ;; BITCH DO YOU UNDERSTAND??

something like 2 + 4*x is BETTER than (+ 2 (* 4 x)), ALSO 2 + (4*x) is just TOTALLY STUPID LEARN TO CONTEXT FREE PARSE IN YOUR HEAD!!!!

Look I doubt any of this is getting through to the smug lisp newbies and the C faggots (even more inexperienced than smug lisp newbies) but as a summary:

* Every language (ignoring shit ones) is different and will stretch your mind and let you program in a new way
* Lisp has prefix notation and s-expression because this works beautifully with homoiconicity, macros etc
* Infix arithmetic is more readable, easier to manipulate algebraically so it IS simply better -- this does not detract from the beauty and elegance of Lisp
* THERE IS NO LANGUAGE WAR/CONTEST, IF YOU DONT KNOW HOW TO PROGRAM WELL IN EVERY SINGLE LANGUAGE YOU FAILED ARUGING ABOUT PROGARMMING LANGUAGE CHOICE IS FOR CHILDREN AND REDDIT USERS.

.... I think that I had a point..... didn't I?

The reason prefix notation is better is because you have a single uniform representation of code and [u]data[/d], the language is homoiconic.

If you mean the fact that in Lisp everything is a car, a cudder, or a paren (a list generally), then yes, I agree. The car of any SEXP is the operator; the cudder are the arguments. This way, you can clearly see the operator of any expression. The prefix notation also makes the INDENTATION prettier.

The reason fucking men in the ass is better than fucking women is because you have a single uniform representation of gender, the fucking is homosexual.

(= PENIS ASS) ;; BITCH DO YOU UNDERSTAND?

I DO NOT NEED TO EXPLAIN THIS ANY FURTHER, THE TERM HOMOSEXUAL SHOULD BE PROOF ENOUGH.

>>41
The reason prefix notation is better is because
...it's easier to parse. Especially back then when LISP was still remotely relevant. Zing!

>>47
Back then?  They didn't have Haskell back then, how could they have parsed Lisp?

protip:
it's (+ a b) because '+' is a function

>>48
It is a mystery.

PS: Haskell reeks.

TESTING

Last test

4.*(73.*(5.+(10.+(8.-(8)))))

Valid Ruby

int a = 4 * (73 + 5);
As opposed to
(setf a (funcall #'* 4 (+ 73 5)))
Tell me which one is easier to read (HINT: it's not the latter)

Oops slight error in the CL:

(setf a (funcall #'* 4 (funcall #'+ 73 5)))

>>55
and why setf? maybe a simple (with) would be ok. something like

(with var a = (* 4 (+ 73 5)) in ...)

>>57
No, you cannot use with, this is outside the problem domain.

>>57
What the fuck is (with)?

>>56
Don't you mean (setf a (apply #'* (list 4 (apply #'+ (list 73 5)))))?

>>59
It's a macro which allows you to make closures.

>>61
But why do you guys keep talking about it like it's standard?

Because it's in the CL ansi standard.

>>62
it's not standard, then again neither is (iter), yet everybody uses it. It's a general binding macro, includes let, multiple-value-bind, and stuff.

>>64
Iterate I know, but I've never seen with mentioned outside /prog/.

>>63
l2hyperspec

>>65
maybe I'm the only one here who uses with, so you everytime you see it here it's because i'm using it.

>>67
I think that's very likely.

>>68
yes.
but i'm not >>59. then again it's not a macro to create closures.

>>14
wow, what a fail language.
here's fizzbuzz in a much cleaner language:
: d dupd mod zero? ;
100
[
 1+ 15 d [ drop "FizzBuzz" ]
 [
  3 d [ drop "Fizz" ]
  [
   5 d [ drop "Buzz" ] when
  ] if
 ] if .
] each

>>70
That CL version is maybe more verbose than necessary.

>>71
all CL is more verbose than necessary.

>>72
All CL is exactly as verbose as necessary.

>>73
x g f >>> [code](f (g x))[code]

>>74
Your first example is insufficiently verbose.

(loop for i from 1 to 100                                             
      do (cond ((= 0 (mod i 15)) (format t "FizzBuzz~%"))              
               ((= 0 (mod i 3))  (format t "Fizz "))                   
               ((= 0 (mod i 5))  (format t "Buzz "))                   
               (t                (format t "~a " i))))

>>76
Forgetting some newlines there?

>>76
I didn't think it was possible for anyone to fail FizzBuzz. Obviously, I was horribly mistaken.

>>75
how so?

That lisp crap isn't taught in my skool. Best decision they ever made.

write a macro in lisp

(with a = 3 + 4 * x)

>>78
Write a program that prints the numbers from 1 to 100. But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz".
Looks fine to me.
