# Deon programming language V0.9.5
My computer programming language made with LEX/YACC written in C. (interpreted)

# Downloads
Supported operating systems and downloads:

# Hello World.
Hello world in Deon.

```
def main: 
{ 
    print["hello world"];
};
call main;
```

# Variables
* Variables support "type juggling" where types are assumed at runtime.
* Variables can be assigned to each other even if they are different types.

```
/* main function */
def main:
{
	my_var = 121231; /* int */
	print[my_var];
	my_var = -123.122;  /* double */
	print[my_var];
	my_var = "cool string"; /* null terminating string */
	print[my_var];
	my_var = 'c'; /* char */
	print[my_var];
	my_var = { print[ "hello world" ]; }; /* lambda function */
	call my_var;
};
call main;
```

# Expressions
* As ov v0.9.5 expressions are only supported for int types, I need to recode the entire expression parsing system
to support up to doubles.

```
def main:
{
	var = 10 + (5 * 2 / (11 % 2));
	/* should print 20 */
	print[var];
};
call main;
```

# Scope
* As of v0.9.5 there is not scope inside of this programming language.

```
/* changes var from 10 to 100 */
def another_function:
{
	var = 100;
};

def main:
{
	var = 10;
	/* should print 10 */
	print[var];
	call another_function;
	/* should print 100 */
	print[var];
};
call main;
```

# Logic
* while loops are if statements
* As of version 0.9.5, logic conditions must only be variables.

### If statements
* As stated above, if statement conditions must be a variable.

```
def main:
{
	var = 1;
	if[var]: /* condition must be a variable */
	{
		print["var was 1"];
		var = 0;
	};
	if[var]:
	{
		print["this wont print! (or shouldnt)"];
	};
};
call main;
```

### While loop

```
def main:
{
	var = 1;
	/* loop that runs forever */
	while[var]:
	{
		print["this will run forever"];
		print["it also wont stack overflow, so dont worry"];
	};
};
call main;
```

# Functions
* Functions can be defined as variables (lambda) or defined normally.

```
def my_function: 
{
    some_function = {
      print["hello world"];
    };
	call some_function;
};
call my_function;
```

# Redefinitions
* As of v0.9.5 everything in this programming language can be redefined. That means everything, including the function that
is currently being executed.

```
def main:
{
	main = {
		print["i just redefined main"];
	};
};
call main;
call main;
```
