        A compiler written for fun to learn about Zig.

    







**Disclaimer**: The grammar, found in `grammar.ebnf`, has not been validated to reject erroneous code. There is also no semantic error handling at the moment so variables are not checked for existence for example. I need to generate a symbol table over the AST before the code generation phase. 

## Syntax

The syntax is intentionally simple to make this a Zig learning experience rather than one of compiler design. I may extend it to include other features that are relatively simple like functions.

**Datatypes**: Only integers are valid at the moment.

**Keywords**: _if, while, end, print_.

### Example Usage

Source file:

```

x = 10/2

y = 5*2+1

if (x <= y) print x+2 end

while (y >= x)

    print y

    if (y == 7)

        x = x - 1

    end

    y = y - 1

end

```

Translated output (python for now):

```py

x = 10 / 2

y = 5 * 2 + 1

if x <= y:

	print(x + 2)

while y >= x:

	print(y)

	if y == 7:

		x = x - 1

	y = y - 1

```
