General Discussion / Computer C and C++ Help / File reading with c/c++

on: 18 August, 2011, 09:09:10

I want to be able to do this on a file:

Code: Select All | Copy To Clipboard

1	myChar = getTheNthCharOrSomething(9);

that for example in pseudo-code, getTheNthCharOrSomething() is this:

Code: Select All | Copy To Clipboard

1
2
3

char getTheNthCharOrSomething(where) {
    return file.charAt(where);
}

file is a global var.

General Discussion / Computer Projects and Ideas / Designing Happy - OOP

on: 16 July, 2011, 11:25:10

Ok, I'm trying to add OOP to Happy.
I only have a small problem:

Where do I place te objects, and how big?

It is simple with objects like this:

Code: Select All | Copy To Clipboard

type point[2] {
    ubyte x;
    ubyte y;
}

// And in the program or global declarations:

point lol;

I can place this with the other vars after the code, and I know I need 2 bytes of space

But even this approach gives problems:
For example, how do I give it initial values?

Amd when using the stack, How do I know the amount of space left?

And this gives even more problems:

Code: Select All | Copy To Clipboard

type string[] { // Yup, no native support
    ubyte[] value;
    
    empty create(ubyte[] in) { // empty is a subroutine type
        // Loop and copy the string
    }
}

This one doesn't make sense, because we have the same data twice in RAM.

Code: Select All | Copy To Clipboard

type enemy[10] {
    ubyte x;
    ubyte y;
    ubyte[8] sprite; // The monochtome sprite data

    empty move(sbyte dx, sbyte dy) {
        x = x + dx;
        y = y + dy; // update the pos
    }
}

To make it short:
1. Happy doesn't always know how big it is
2. How can initial values be set?
3. How do I stop the program from corrupting things in RAM, with a ever-growing stack?

This is my happy thread CURRENTLY REWRITING THE WHOLE THING. Because it became a mess, and I got some new ideas to make it better. (Learn While Doing lol) I am working on a programming language for the 83 etc, (But it is easily retargetable, so anyone who knows er, ti-nspire asm for example, could edit some strings and is ready!!) I made it with JavaScript ~~(I have a strange relation with that language)~~ working on a C++ version, so there is an exe for the winows guys coming!! Current Features: -Nice name (Happy) -Operator Precedence -Somewhat optimized expressions (Crenshaw hates me now) -Really platform-independent because it's made with JS -Nothing more yet... To show what it is currently able to do: Spoiler for Input and Output: 4+-(5+~3) is translated to: ld hl, 4 push hl ld hl, 5 ld de, 3 ld a,e cpl ld e,a ld a,d cpl ld d,a add hl, de pop de ex de,hl ld a,e cpl ld e,a ld a,d cpl ld d,a inc de add hl, de That may seem much, but most of it is the super inefficient unary operator - and ~. It is able to do * and / too, but that's not a z80 command, and I have no libs yet... It also optimizes a VERY little bit: for example, it doesn't fall for this one: (Which is also good to have no precedence) ((((2+3)4)+5)/7) is translated to: ld hl, 2 ld de, 3 add hl, de ld de, 4 call multiply ld de, 5 add hl, de ld de, 7 call divide Isn't that nice? Spoiler* for Log:: 10-06-2011 Started development with a Crenshaw tutorial. 13-06-2011 Because of the horrible output quality, I started rewriting everything. 14-06-2011 Announced it here, posted a poll about precedence. Almost finished the expression parser the same day. 15-06-2011 Getting the pushes and pops right was harder than expected. 16-06-2011 Adding variables (sort-of) and function calls, Still fighting with pushes and pops. 17-06-2011 Still fighting with those #$%^pushes and pops, made a website for it. v0.0.2 18-06-2011 Assignments!! I think I finally fixed the pushes and pops. v0.0.3 19-06-2011 A few things that I want to make better, and going to make it MULTILINE YAY Between: v0.0.4 21-06-2011 It was slowly turning into a mess, so I decided to start over. REWRITING YAY Until now: rewriting almost complete, rewriting it in C++ so it is more usable Spoiler for Syntax: var1,var2=nn-nn+(nn--nn)*~nn/var3 nn is a number 0<nn<65535 var is a variable Link to test it yourself (Please do that!!)

5	Calculator Community / TI Z80 Calculator Projects / Operator precedence...	on: 14 June, 2011, 08:16:14
As some of you know I'm working on a programming language for the TI83/84 etc, but I've got a question: Do you guys want operator precedence? It would be less optimized (pushes and pops), but since the compiler is not on-calc, I can work on this. It would also mean more work for me (but that's not really bad)

General Discussion / Computer Projects and Ideas / [JS] A small 4-bit interpreter/emulator

on: 24 May, 2011, 14:43:52

I was bored, and I have a obsession with... Nevermind, here it is.

Made with my iPod Touch (no copy-paste used, everything is ~~hand-coded~~thumb-coded)
Why js?
~~Because I hate Apple Waaah.~~ Er, no, because I can't program in any other language with it thanks to Apple. (ok, it's jailbroken, but php is just ... not right for this and bash... There are still windows users here...

Why 4-bit?
To keep it simple, stupid.

And...?

Calculator Community / Axe Language / getKey question

on: 17 March, 2011, 16:11:51

I'm trying to make a key remapping function for DionJump, in Settings, users can edit the keys and the number is saved to an appvar.

But when I try to check the keys, it doesn't work...

Code: Select All | Copy To Clipboard

:If getKey({K+2}) // K is the pointer to the appvar.
: ...
:End

Here is my source, the getKey is changed back to getKey(41), to make the game work. Please don't ask questions about the rest of the code, it isn't really good code, I know that...
WHOA, that's BIG, BIIIIIIIIIIIIIIIIIIIG, did I make that in 4 days Huh?

10	General Discussion / Introduce Yourself! / Hello everybody	on: 11 March, 2011, 23:12:27
A little introduction. I started programming in Axe about three months ago, and haven't written a single line of TI-BASIC since then. I am also able to program in some computer languages: Java, PHP, (a little bit) C, (X)HTML and JS, but those two aren't really computer languages. I live in the Netherlands, so if I make any language mistakes, correct me. I have written a Doodle Jump clone called DionJump in Axe. Currently I'm adding functions to it. I'm also making a clone of Angry Birds, but that one isn't doing anything useful yet. I hope I'm going to learn much here. Yrnfsh Edit1: added the word "language" Edit2: whoa, got some sort of ninja'd on my FIRST post
