Hello! I'm LunaStev, the developer of Wave.

We are very pleased to introduce Wave 'v0.1.0-pre-beta' — This update supports the import function and UTF-8, allowing you to output other characters, unlike previous versions that only supported ASCII.

✅ Added Features​

📦 Local File Import Support​

  • Introduced import("..."); statement in Wave syntax.

  • Supports importing .wave source files relative to the current file's directory.

  • Prevents duplicate imports automatically using an internal HashSet.

  • Imported files are parsed, converted to AST, and merged into the main program at compile time.

  • Enables modular project structure by allowing multi-file composition.

🔧 Bug Fixes​

🐞 UTF-8 Handling in Lexer​

  • Fixed tokenizer crash on non-ASCII characters.

  • Lexer now correctly processes UTF-8 multi-byte characters, enabling support for Korean and other languages in source code.

🐞 Underscore (_) Support in Identifiers​

  • Variable and function names can now contain underscores.

  • Lexer now treats identifiers like my_var or some_function as valid.
