btrc: A Modern C-Like Language with a Twist

is a statically-typed language that transpiles to C, aiming to provide a modern and ergonomic take on the classic C programming language. With its unique blend of features and a dash of artificial intelligence, btrc has been gaining attention among developers and researchers alike.

In this article, we'll delve into the world of btrc and explore its key features, compiler pipeline, and some exciting examples that showcase its capabilities. So, let's dive in!

is defined through a formal EBNF grammar, which mathematically defines every keyword and operator; an algebraic AST spec defines every node type for the language graph; and a compiler pipeline consumes both the spec and the graph, walking your code through six stages (lexical analysis, syntax analysis, semantic analysis, intermediate code generation, code optimization, code generation). This pipeline is responsible for producing C-like code that can be compiled with standard tools like GCC or Clang.

One of the standout features of btrc is its ability to generate high-quality C code while maintaining a modern and ergonomic syntax. The language includes classes, generics, type inference, lambdas, f-strings, collections, threads, GPU compute, automatic reference counting, exception handling, and a standard library – all while staying compatible with C. This means that developers can write btrc code once and compile it to run on any platform that supports C.

also features nullable types, optional chaining, and null coalescing, which provide additional safety guarantees without sacrificing performance. The compiler warns when using .field on a nullable type without ?, helping catch null dereferences at compile time.

In terms of memory management, btrc uses lightweight automatic reference counting (ARC) for memory management. Every class instance tracks how many references point to it. When the count reaches zero, the object is automatically destroyed. No garbage collector – deterministic cleanup at scope boundaries.

also includes built-in threading with spawn, typed Thread, and Mutex. Captured class instances are ARC-safe – the compiler increments the reference count at spawn time and decrements it when the thread completes.

Furthermore, btrc has a Unity-inspired 3D game engine built on WebGPU rendering. A ball on a ground plane with WASD movement, space to jump, real-time shadows, and SDF raymarching – all in ~570 lines of btrc across 11 engine modules. The engine is modular: GameObject with physics, Camera with follow behavior, Light and Material for shading, Ground checkerboard and Sky gradient, Scene compositing with a WGSL raymarching shader, Input for keyboard, Time for frame timing, and Renderer tying it all together.

ships with a VS Code extension (src/devex/ext/) and a Language Server Protocol implementation (src/devex/lsp/) that reuses the compiler's own lexer, parser, and analyzer. Diagnostics match exactly what the compiler reports – there is no separate linting pass. The LSP server maintains a two-tier cache: the current analysis (which may have parse errors while you type) and the last fully successful analysis.

compiles through six stages, with two formal specs driving the front-end: src/language/grammar.ebnf defines all keywords, operators, and syntax rules; src/language/ast/ast.asdl defines all AST node types using Zephyr ASDL. A structured IR separates lowering from emission.

In conclusion, is a unique language that brings together the best of modern programming languages with the power of C. Its compiler pipeline, features, and examples showcase its capabilities and make it an exciting project to follow. Whether you're a seasoned developer or just starting out, btrc is definitely worth checking out.
