# mclang rev2
This is the second revision of [MCLang](https://github.com/mc-lang/mclang) now written in rust!
## Goals
✅ - relatevely usable by normal programmers
✅ - speed comparable to unoptimised C (sometimes)
❌ - static typing
❌ - self hosted (maybe better if not? Since rust is fast asf)
❌ - multiplatform (~~windows~~, linux and mac)
❌ - interop with other languages
❌ - package manager
❌ - installer
## Documentation
The docs are currently are just made in MarkDown.
You can find the docs [here](/docs/index.md)
## Credits
[MCotange](https://github.com/MCorange99) - The one and only me, the creator and current maintainer or mclang rev1 and rev2

# Instructions And Keywords
This explains all of the instructions and keywords
## Instructions
Instructions modify the stack, the stack is an array, i will be using typescript to show how each instruction works
```ts
let stack: number[] = [];
```
### PushInt ("Any Number")
PushInt pushes one number on the stack.
Usage:
```forth
420
```
How it works:
```ts
// num = 420
stack.push(num);
console.assert(stack == [420]);
```
### PushStr ("Any String")
PushStr pushes 2 things on the stack, string length and string pointer
Usage:
```forth
"Henlo world!\n"
```
How it works:
```ts
stack.push(str_len);
stack.push(str_ptr);
```
### Print ("print")
Print just prints a number from the top of the stack into stdout
Usage:
```forth
69 print
```
How it works:
```ts
num = stack.pop()
console.log(num);
```
### Dup ("dup")
Dup duplicates the top most number on the stack
Usage:
```forth
69 dup
```
How it works:
```ts
stack = [12];
a = stack.pop();
stack.push(a);
stack.push(a);
console.assert(stack == [12, 12]);
```
### Drop ("drop")
Drop removes the top most number on the stack
Usage:
```forth
69 drop
```
How it works:
```ts
stack = [69];
stack.pop();
console.assert(stack == []);
```
### Rot ("rot")
Rot moves the third number from the top of the stack and moves it to the top
Usage:
```forth
1 2 3 rot
```
How it works:
```ts
stack = [1, 2, 3];
let a = stack.pop();
let b = stack.pop();
let c = stack.pop();
stack.push(b);
stack.push(a);
stack.push(c);
console.assert(stack == [3, 1, 2]);
```
### Over ("over")
Over takes the second number from the top of the stack and copies it to the top
Usage:
```forth
1 2 over
```
How it works:
```ts
stack = [1, 2];
let a = stack.pop();
let b = stack.pop();
stack.push(b);
stack.push(a);
stack.push(b);
console.assert(stack == [1, 2, 1]);
```
### Swap ("swap")
Swap swaps the first and second numbers from the stack
Usage:
```forth
1 2 stack
```
How it works:
```ts
stack = [1, 2];
let a = stack.pop();
let b = stack.pop();
stack.push(a);
stack.push(b);
console.assert(stack == [2, 1]);
```
### Plus ("+")
### Minus ("-")
### Mul ("*")
### Equals ("=")
### Gt (">")
### Lt ("<")
### NotEquals ("!=")
### Le ("<=")
### Ge (">=")
### Band ("band")
### Bor ("bor")
### Shr ("shr")
### Shl ("shl")
### DivMod ("divmod")
### Mem ("mem")
### Load8 ("@8")
### Store8 ("!8")
### Syscall0 ("syscall0")
### Syscall1 ("syscall1")
### Syscall2 ("syscall2")
### Syscall3 ("syscall3")
### Syscall4 ("syscall4")
### Syscall5 ("syscall5")
### Syscall6 ("syscall6")
### None ("None")
## Keywords
### If ("if")
### Else ("else")
### End ("end")
### While ("while")
### Do ("do")
### Macro ("macro")
### Include ("include")
