# Syntax
> This language is still in development, the syntax can be changed at anytime.
Hazure is a [free-form](https://en.wikipedia.org/wiki/Free-form_language) syntax style, so the indentation is purely for readability.
```sml
fun main: void = do
@write("Hello, World!");
end;
```
is the same as
```sml
fun main: void = do @write("Hello, World!"); end;
```
Hazure is also [expression-oriented](https://en.wikipedia.org/wiki/Expression-oriented_programming_language) like OCaml. There are currently 10 expressions:
1) Comment
```
-- Comment!
-{ Block Comment }-
```
2) Values / Types
```sml
1
true
"string"
variable
```
3) Unary and Binary
```sml
1 + 2
!true
```
4) Call and Intrinsic. Intrinsic starts with a `@`
```sml
@write("Hello")
foo("bar")
```
5) Pipeline
```sml
"Hello, World" |> @write(_)
```
6) Variable declaration
```sml
let foo: int = 727;
let bar: string = "Hi";
let baz: boolean = true;
```
7) Function declaration
```sml
fun foo: void = @write("void returns nothing");
fun bar (x: int): int = x + 1;
fun baz (x: int) (y: int): int = x + y;
```
8) If conditions
```sml
let cond: bool = true;
if cond then
@write("True");
else
do
@write("False");
end;
end;
```
9) Case matching
```sml
case 1 + 1 of
| 2 -> @write("Yes");
\ @write("How?");
end;
```
10) Do notation. It allows you to have multiple expression because something like right hand side of the function declaration `fun a: int = ...` can only have 1 expression. Do allows you to bypass that.
```sml
do
@write("Hello, World");
foo(bar);
let baz: int = 6 + 10;
end;
```
Hazure isn't a scripting language, so, you will need a main function.
```sml
fun main: void = do
@write("Hello, World");
@write(34 + 35);
end;
```
