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):

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
