A nogc utility library for the D programming language. Joka provides data structures and functions that work without garbage collection, offering precise memory control. It is designed to complement the D standard library, not replace it.

• joka.ascii: ASCII string utilities
• joka.cli: Command-line parsing utilities
• joka.containers: General-purpose containers
• joka.io: Input and output functions
• joka.math: Mathematical data structures and functions
• joka.memory: Functions for dealing with memory
• joka.types: Type definitions and compile-time utilities

• JokaCustomMemory: Allows the declaration of custom memory allocation functions
• JokaGcMemory: Like JokaCustomMemory, but preconfigured to use the D garbage collector

WebAssembly is supported with the BetterC flag, but something like Emscripten is needed to make it work. If you encounter errors with BetterC, try using the -i flag.

Start with the examples folder for a quick overview. To try an example, run:

./scripts/run_example examples/_001_hello.d
# Or: .\scripts\run_example.bat examples\_001_hello.d
# Or: ./scripts/run_example examples/_001_hello.d ldc2

Here are a few things I like about Joka that I don't see in other libraries:

• Minimalistic: Avoids abstractions
• Focused: Doesn't try to support every use case
• Simple: Uses a single global allocator, set at compile time
• Fast: Compile times are blazingly fast
• Friendly: Includes many examples

Because the D garbage collector can be used as a global allocator.

Because I can and it's useful sometimes.

Primarily for Parin, a game engine I'm working on.

• Maybe think about IO.
• Maybe "copy-paste" this thing: subprocess.h
