I'm building a Lisp, called Valutron. I am implementing its compiler-interpreter in Objective-C.
It has some unique features: first, it offers what are called V-expressions, an alternative notation for writing code. Second, it offers a comprehensive object system inspired mainly by that of SmallTalk-80, one of the earliest Object-Oriented languages, and by Common Lisp's CLOS, Common Lisp being the first object-oriented language to be standardised.
This object model is implemented atop the Objective-C runtime, which I have extended with support for Double Dispatch to enable the availability of CLOS' characteristics multimethods.

Without you illustrating your desired result I can't really tell you anything. You currently (in the picture) have three button like things which could be placed using absolute coordinates. If you want to place them relative to the window size use a GridLayout.
But I suggest you play around with the different layouts and get a feel for what they actually are, or read about them more. Then you can make the decision.
But if you want someone else to tell you offer a better description. Like throw out 4 different examples of desired situations.

I want the behavior of FlowLayout, but want one set of components to left-justified and the other set to be right-justified.
Basically, the components on the left will be "glued" to the left and their position will be relative to the left border (just like a FlowLayout(LEFT)); the components on the right will be "glued" the right and their position will be relative to the right border (like FlowLayout(RIGHT)).
Resizing the panel will increase/decrease the spacing between the two sets of components.

There's a reason that nobody writes in Smalltalk or Common Lisp; because they're old languages and modern languages have improved since then.

Sure, you can learn everything on your own. The problem is you need a lot discipline to educate yourself the way a university does. Besides that a university would offer group projects and train you to get into a proper development process for something like SE. A university will also introduce you to things you might not think of yourself. You'll also have to build a good portfolio instead of being able to just wave around a piece of paper. Don't underestimate the discipline part, it's easy to slack or get sidetracked if you're the one that sets the deadlines.

>>51564083
It is a Lisp.
My primary references in building Valutron are ISO/IEC 13816:2007 (Programming Language ISO LISP), from which I mainly draw from its description of ILOS, the object system it uses, and also Revised [6] Report on the Algorithmic Language Scheme, from which I derive general inspiration as well as the semantics of continuations.
>>51564096
Here's a very simple example of VOM, the Valutron Object Model:// let's define a 'get-hello-world' generic
defgeneric get-hello-world (object some-object) => string;
// let's define a 'hello' class
defclass hello (object)
{
slot string hello : initarg hello:;
slot string world : accessor getWorld, initarg world:;
}
defmethod get-hello-world (hello some-object) => string
{
let result = copy(some-object.hello);
append(to: result, some-object.getWorld);
result
}
let aHello = make-instance (hello: "hello", world: "world");
// the dollar $ is an alternative form of method dispatch syntax;
// it passes its (left-associative) pre-component as first argument
let aLambda = { () => integer | print(stdio, aHello$get-hello-world()); };
aLambda();

How do you do that with arguments?
Because if I haveint fooTheStuff(int32 arg, real32 arg2, disgustinglyLongStructName* input, int (*fThe)(disgustinglyLongStructName)){
return fThe(input);
}
Or just many arguments I'd rather break it up like this.int fooTheStuff(int32 arg,
real32 arg2,
disgustinglyLongStructName* input,
int (*fThe)(disgustinglyLongStructName)){
return fThe(input);
}
Because this is easier to read for me. But there can be plenty of cases where the former example is there because they straddle my limit for how long I want args to be. I think I'd find this very hard with only parenthesis's. At the very least it doesn't make it as clear to me mentally. I see the braces begin in C and I seem them close. That makes it plenty clear what the function body is. But if I were to have this straddling case I don't feel nearly as sure anymore.
What's the case for not using braces? Why not make them optional? I haven't programmed in lisp obviously.

Available for use. But I was asked for a code example, and so thought it better to use V-expressions, the algebraic syntax available in Valutron, that I could show where Valutron offers differences. This is all explained in my original post.
>>51564488
The thing about Lisp is that its syntax is based around parenthesis so there is no concept of "braces".
Like, in JavaScript (I'm using it because its a dynamically typed language with curly braces) it might be:function foo (x, y) {
...
}
In Lisp it's like this:(define (foo x y)
...)
In Lisp you show nesting by indenting things correctly. And if a function takes a lot of long arguments, you indent the arguments to the same position(some function
that
takes
(a lot of)
arguments)

(defn width [rectangle]
(let [[[x1 y1] [x2 y2]] rectangle]

(contains-point? outer x2))
true

>>51564618

>>51564602
thanks
>>51564637
Makes sense.
Is there something like pep8/jslint for Clojure?
>>51564618
For function calls I (my personal style) indent every argument to the same column, but for syntactic things like 'if' or 'let', put everything 2 spaces in.(defn square? [rectangle]
(if (= (height rectangle)
(width rectangle))
true
false))
(defn area [rectangle]
(* (height rectangle)
(width rectangle)))
(defn contains-point? [rectangle point]
(let [[[x1 y1] [x2 y2]] rectangle
[x3 y3] point]
(if (and (<= x1 x3 x2)
(<= y1 y3 y2))
true
false)))
(defn contains-rectangle? [outer inner]
(let [[x1 x2] inner]
(if (and (contains-point? outer x1)
(contains-point? outer x2))
true
false)))
Note that "(if X true false)" is redundant, just write "X"
>>51564700
Seems like a 'good enough' style, and lacking any of my own, I'll adopt it. Thanks
>>51564543
I'm not sure I follow. Exactly how does lisp not have a concept of braces? Looking at(define (foo x y)
...)
It seems pretty clear to me that the opening paren (first character) is the brace equivalent here. It opens and closes the function.
Your second example seems very odd to me. Perhaps you could clarify it by labeling things more clearly. Because as is I can't really say if you're making the point I think you're making. I don't see any nesting going on except maybe(a lot of)
Which I can't really understand. (you're allowed to group arguments? Arguments can have names containing spaces?)

>Note that "(if X true false)" is redundant, just write "X"
Oh, and I know this, but the tutorial that I'm following has Midje tests which check the output for 'true' and 'false', so I have to explicity return those (I think).
Actually, now I think about that, I just assumed that to be the case, but false and nil are equivalent, right? And anything not nil/false = true. So the tests should pass either way...?
>>51564779
OK, just tested that, and they still pass when not explicity returning true/false.
Thanks!
>>51564762
I'm sorry.
In Lisp, () denotes a "list".
To evaluate a Lisp expression that is a list, it looks at the first item of the list. This first item is usually the function name that you are calling, which is why "(f x)" is equivalent to "f(x)" in other languages ("f" is the function being called).
Constructs like "if" are also just represented as lists. (if x y z) is essentially the same as "x ? y : z" or "if (x) { y } else { z }".
When you define a function, that definition syntax is again just a list. The special symbol "define" means that we are defining something.
(define <function signature>
<body>)
The (a lot of) example I gave was just to demonstrate indentation. In that example, the "some" function would be called. "(a lot of)" would also call the "a" function.

I'm not entirely sure how I feel about that. It seems neat on surface to have a syntax to say many different things and just change a keyword (or "symbol" as you call it) but I'm not entirely sure how I feel about it in practice.
It's very compact for sure. Something many other languages fail at.
I was playing codingame's Clash of Code and just got keked hard by some fag writing Python. I was writing in C and got the task to reverse every word in a sentence (but not the entire sentence itself) and by the time I had finished typing in strtok and setting up my loop the fag was already finished.
Fuck scripting langauges.
>>51564896
The reason I say "symbol" is because 'define' is just like 'x' and 'f', they're all "symbols". The syntax has hardly any exceptions or inconsistencies.
The cool part about lists in Lisp is that in Lisp code you work with data that is of the same form that Lisp code is represented in.
Therefore it's very easy to implement a feature so that Lisp code may be generated by other Lisp code during compilation. Macros are what makes Lisp such a powerful language; because the language is so simple, and features may be added easily through macros, you end up with an infinitely powerful and expressive language.

The equivalent handwritten assembly binary is less than 1KB, but the "optimizing" GCC can't get it under 4.4.

"Can't beat the compiler" is in terms of translating C to assembly. Doesn't help you one bit if your program is poorly written in the first place.

I don't believe you know what a Lisp is. Please consult McCarthy's Recursive Functions of Symbolic Expressions and Their Computation by Machine and The Lisp Programmers' Manual 1.5. Next, consult the Common Lisp ANSI standard, then ISO/IEC standard 13816:2007 (Programming Language ISO LISP), and finally Revised [6] Report on the Algorithmic Language Scheme. Once you have read those, you can come back to me with arguments - if you have any left :-)

well fucking shit I did it
i created a C program that compiles properly that's under 1KB
Granted it segfaults as soon as you try to run it but it fucking works.

End-to-End using a password, CryptoJS?
Alright, I need help /g/entlemen. Say I want to do something to a variable via multiprocess. In UNIX, I've read that I'd need to use either shm_get() or mmap() but I didn't quite get how these work. Here's what I have#define N 4
int main () {
pid_t pids[N]
int i;
pid_t pid;
for(i = 0; i < N; i++) {
if((pids[i] = fork()) < 0) {
perror("Fork");
abort();
}
if(pids[i] == 0) {
//do something to a variable
//example: x++, but I want x to be visible/shared with all children processes
exit(1)
}
}
while(pid = waitpid(-1, NULL, 0)) {
if(errno == ECHILD) {
break;
}
}
return 0;
}
Something like that. How exactly can I "share" x with the processes?
>>51565601
Just like your browser. Just the way you like it.
>>51565617

Oh... User accounts you mean?
Absolutely not! Went out of my way to devise a scheme to allow (myself and other) users to casual identify each, without using sessions or cookies. I've need to be especially care around networked devices that share the same IP...
I've accounted for that, but not sure if that code works yet, because you'd need a fairly rare condition to test the edge case of conflicting machines.
>>51565292
do you have a repo for this? I'm interested in following development.
>>51565721
What? No. Encrypt messages on the client before sending them to the server and then decrypt them at the receiver using the same password.
Just enter it once you enter the room.
>>51565726
Unfortunately it is currently proprietary software. Perhaps I can release the source code under a more permissive license in the future.
>>51565683
Very funny. If you know how to program C and build your abstractions well this is a non issue. (assuming your platform isn't vulnerable)

Mostly, but there have been very few big projects that never see severe vulnerabilities.

If there are two things I am direly serious about, they are liberty and nigger-loving.
>>51565759
>>51565785
The only real way to do it, is https. But for this, I don't want any encryption at all.
But I do want cogent machine id's without using cookies or database backed sessions.
Not sure if that's possible over http though. :/

in real life you use objects. like someone built a car for you (if you own a car), you probably didn't build yours from scratch. and it has a relatively simple interface for you to use it, with the gas pedal and steering wheel and such. when you want to start the engine, you just turn the key and it does all sorts of things automatically so you don't have to worry about the spark plug and whatnot. now take this concept of objects that you can use with a relatively simple interface into the programming world. that's Object Oriented Programming™.
