⚡ TinyCompiler

    


        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 purely of compiler design. I'm not a compiler engineer, so don't expect big things haha. I may extend it to include other features that are relatively simple like functions.

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

**Keywords**: _var, int, if, while, end, print_.

### Example Usage

Source file:

```

var x: int = 10;

var y: int;

y = 5*2+1;

if (x <= y) 

    print x;

else

    print y;

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

y = 0

y = 5 * 2 + 1

if x <= y:

	print(x)

else:

	print(y)

while y >= x:

	print(y)

	if y == 7:

		x = x - 1

	y = y - 1

```
