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

We are very happy to introduce Wave v0.0.8-pre-beta —
a version that officially brings first-class pointer support to the language.

Wave was designed with low-level capabilities in mind, and in this version,
we’re making a major leap in that direction.

✅ Added Features

🧠 Pointer System: First-Class Pointer Support in Wave

  • Introduced ptr type syntax for defining typed pointers

    → Example: var p: ptr;

  • Implemented &x address-of operator

    → Compiles to LLVM IR as store i32* %x

  • Implemented deref p dereference operator

    → Generates IR as load i32, i32* %p

  • Supported pointer-based initialization

    → var p: ptr = &x; is now fully parsed and compiled

  • Enabled dereferencing for both expression and assignment

    → Example: deref p = 42; is valid and stored directly via IR

  • Address values can be printed as integers

    → %ld used for pointer-to-int cast in formatted output

    → println("address = {}", p); prints memory address

🔧 Bug Fixes

🐛 Fixed Pointer Initialization Parsing Issue

  • Changed VariableNode.initial_value from Option to Option
  • Allowed &x to be accepted as a valid initializer expression

🐛 Fixed LLVM IR Crash on AddressOf Expression

  • Added support for Expression::AddressOf in IR generation
  • Prevented crash by checking for variable reference inside address-of

🐛 Fixed printf format mismatch for pointers

  • %s → %ld for pointer values
  • Ensured correct casting of i32* to i64 before printing

✨ Other Changes

🧠 Improved Format String Handling in IR

  • Added dynamic format string generation based on argument types
  • Format strings now automatically adapt for int, float, and pointer types
