bldr

This is my personal high-performance build system for the polyglot monorepos I frequently torture myself with. Featuring: runtime dependency discovery, lock-free parallel execution, incremental compilation; built entirely in D because it was fun to do.

Stuff I Wasted Time Doing During My Last Job:

• Dynamic Build Graphs — Actions discover dependencies at runtime, eliminating code generation friction
• 32 Language Handlers — C/C++, Rust, Go, D, Zig, Python, TypeScript, Java, Kotlin, Scala, and more
• Three-Tier Caching — Target, action, and distributed cache for maximum reuse
• Work-Stealing Scheduler — Chase-Lev deque, near-linear scaling to 64+ cores
• Hermetic Builds — Native sandboxing on Linux/macOS/Windows
• Full LSP — VS Code extension with autocomplete, diagnostics, go-to-definition
• Query Language — Bazel-compatible bldrquery for dependency exploration
• Migration Tools — Import from Bazel, CMake, Maven, Gradle, Cargo, npm, and more

Installation

# macOS
brew install ldc dub && git clone https://github.com/GriffinCanCode/bldr.git && cd bldr && dub build --build=release

# Linux  
sudo apt install ldc dub && git clone https://github.com/GriffinCanCode/bldr.git && cd bldr && dub build --build=release

Quick Start

bldr init                              # Initialize project
bldr wizard                            # Interactive setup
bldr build                             # Build all targets
bldr build //path/to:target            # Build specific target
bldr test                              # Run tests
bldr build --watch                     # Watch mode
bldr query 'deps(//src:app)'           # Query dependencies
bldr migrate --auto CMakeLists.txt     # Migrate from other build systems
bldr explain list                      # Built-in documentation topics
bldr explain testing                   # Read one topic

Builderfile Example

let version = "1.0.0";
let flags = ["-O2", "-Wall"];

target("core-lib") {
    type: library;
    language: d;
    sources: ["src/core/**/*.d"];
    flags: flags;
}

target("app") {
    type: executable;
    language: d;
    sources: ["src/main.d"];
    deps: [":core-lib"];
}

target("tests") {
    type: test;
    language: d;
    sources: ["tests/**/*.d"];
    deps: [":core-lib"];
}

Save this as Builderfile in the project root.

Do not speak to me about the website, I vibe-coded it overnight, but it's fun to look at.
