2023-04-18ast: Create AST visitor to traverse the treeJohnny Richard
In the future we want to have the possibility of traverse the tree and pretty print it or generate binary for other platform like LLVM or transpile to C. This solution also implements the gas assembly x86_64 Linux code generation by using the visitor interface. Signed-off-by: Johnny Richard <johnny@johnnyrichard.com>
2023-04-16Start using string_view on lexer and parserJohnny Richard
This change fixes the memory leak when token got created. Signed-off-by: Johnny Richard <johnny@johnnyrichard.com>
2023-04-15parser: Create parser for function with return statementsJohnny Richard
This is a very limited parser implementation which parses a single function with return type i32 and body containing a return number statement. The parser doesn't show the 'filepath:row:col' when it fails, a future improvement would be display it to easy find where the compilation problem is located. The ast_nodes are taking the token.value ownership (which is a really bad design since not all token.value ownership has been taken causing memory leaking) but we never free them. For a future fix we could use a string_view instead since we never change the original source code. The string_view will also improve the performance a lot avoiding unnecessary heap memory allocation. Signed-off-by: Johnny Richard <johnny@johnnyrichard.com>
