# 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;
```
