MyraLang v0.1.0

Myra - Pascal. Refined.

Myra is a minimal, Pascal/Oberon-inspired systems programming language that compiles to modern C++23 and builds to native binaries through a bundled Zig/Clang toolchain. No external compiler, no build-system glue, no configuration -- point Myra at a .myra file and it produces an executable.

This is the first public release.

Highlights

• Minimal systems language -- Oberon-inspired, only the essential constructs: object types with create/destroy lifecycle and methods, pointers, sets, choices enums, guard/except exception handling, and module exe|dll|lib units.
• Seamless C++ passthrough -- any token Myra does not recognize passes through verbatim to the generated C++. Use C and C++ libraries directly, with no wrapper syntax and no escape hatch.
• Hackable compiler -- the language is defined by human-readable .mld definition files (tokens, grammar, semantics, emitters, helpers) that ship alongside the compiler in bin/res/language/. The grammar is data, not baked into the binary.
• Six build targets -- win64, winarm64, linux64, linuxarm64, macos64, and wasm32, all driven from the bundled toolchain. win64 runs natively; linux64 runs via WSL2; wasm32 emits a self-contained, double-click .html runner with the WASI shim and wasm bytes inlined.
• Compile-time conditionals -- @ifdef gates Myra at the lexer stage (build directives, target selection); C++ #if passthrough handles the generated code. Myra defines and the live TARGET_* symbol reach the C++ compiler as -D defines.
• C linkage control -- cpplink (default) or clink per routine, with DLL and static-library import and export across Myra modules.

Tooling

• Myra.exe -- the command-line compiler. -s source, -o output, -r build-and-run, -d debug, -h help.
• MyraLSP.exe -- a Language Server Protocol server: hover, go-to-definition, find references, rename, document and workspace symbols, real-time diagnostics, folding, semantic tokens, signature help, inlay hints, formatting, and code actions.
• -d debug mode -- an interactive, PDB-based source-level debug REPL for Windows executables.
• Testbed.exe -- the language test-suite runner.

Quick start

Myra -s hello.myra -r

Compiles hello.myra to a native executable via the bundled toolchain and runs it.
