From e927a4b22115e0461db6feeee891256b10650c0e Mon Sep 17 00:00:00 2001 From: Johnny Richard Date: Fri, 14 Apr 2023 23:10:25 +0200 Subject: parser: Create parser for function with return statements 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.
