Hello world in Deon.
|

```

```
|

def Main : {
|
def main:
|

printf[ "hello world" ];

Requirements to making a program:
|
|
||||||
1.) a struct/function.
|
|
||||||
2.) a call statement.

# Variables
|
# Variables
|
||||||
Variables are stored in a hashmap for quick and easy access. Variables also support type juggling. When you define a variable its type will be assumed when parsed.
|
<hr/>
|
||||||
|
- 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 */
|

|

# 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.
|
||||||
```
|
```
|
||||||
myint = 121231;
|
/* changes var from 10 to 100 */
|
||||||
mydouble = -123.122;
|
def another_function:
|
||||||
mystring = "cool string";
|
{
|
||||||
mychar = 'c'; // char
|
var = 100;
|
||||||
myfunction = { printf[ "hello world" ]; }; (statement list)
|
};
|
||||||
|
|
||||||
|
def main:
|
||||||
|
{
|
||||||
|
var = 10;
|
||||||
|
/* should print 10 */
|
||||||
|
print[var];
|
||||||
|
call another_function;
|
||||||
|
/* should print 100 */
|

print[var];

# Logic
|
# Logic
|
||||||
Logic is first evaluated and if deemed valid then a list of statements will be executed.
|
<hr/>
|
||||||
|
- 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.
|
||||||
```
|
```
|
||||||
if [ 10 > 9 ]: {
|
def main:
|
||||||
printf [ "10 is bigger than 9!" ];
|
{
|
||||||
newInt = 100;
|
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;
|
||||||
if [ {int} newInt > 99 ]: {
|
```
|
||||||
printf [ "newInt is bigger than 99" ];
|
### 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
|
||||||
Functions can be declared inside of a struct and accessed by anyone who uses the scope resolution operator. Do not mistake structs as functions just because you can interact with them in the same way. Functions do not have "scope" like structs do. Functions can interact with all elements in the parenting struct including other functions, and those functions local variables.
|
- Functions can be defined as variables (lambda) or defined normally.
|
||||||
```
|
```
|
||||||
def NewStruct : {
|
def my_function:
|
||||||
someFunction = {
|
{
|
||||||
printf[ "hello world" ];
|
some_function = {
|
||||||
|
print["hello world"];
|
||||||
};
|
};
|
||||||
|
call some_function;
|
||||||
};
|
};
|
||||||
call NewStruct;
|
call my_function;
|
||||||
```
|
```
|
||||||
|
|
||||||
# Coming soon
|
# Redefinitions
|
||||||
TCP networking, file handling, and finally loops!
|
- 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;
|
