Blaise is a new self-hosting Object Pascal compiler designed to shed decades of legacy complexity found in Free Pascal and Delphi. It enforces a single language mode, a single UTF-8 reference-counted string type, and a unified automatic reference counting memory model for all classes and interfaces. The compiler targets native code via a QBE backend (with LLVM in development), supports reified generics via monomorphization, eliminates COM-style GUIDs, and ships with its own build system (PasBuild). The project has achieved self-hosting with byte-for-byte reproducible builds, completed phases covering the type system, generics, and debug info emission, and has over 1200 tests. Future plans include an LLVM backend, Windows/macOS ARM64 support, an LSP server, VS Code extension, and a migration analyser for existing FPC/Delphi codebases.
