|
* Overview
|
|
ZTL is a lightweight, portable programming language for permacomputing, game preservation, and indie game development.
|
|
Built in **C99** for cross-platform compatibility (desktop, microcontrollers, and web via Emscripten).
|
|
Designed for simplicity, performance, and creative exploration.
|
|
It is inspired by [[https://wiki.xxiivv.com/site/uxn.html][uxn]], [[http://duskos.org/][Dusk OS]], [[https://lua.org][Lua]], [[https://en.wikipedia.org/wiki/Lisp_(programming_language)][Lisp]], [[https://en.wikipedia.org/wiki/C_(programming_language)][C]], and [[https://ziglang.org/][Zig]].
|
|
|
|
* Key Features
|
|
|
|
** Core Philosophy
|
|
- Simple, portable, lightweight
|
|
- Targets permacomputing, game world preservation, rapid prototyping, and indie games.
|
|
- No macros or object hierarchies—prioritizes clarity and explicit behavior.
|
|
- C/Zig like syntax. Lisp/Lua like development workflow.
|
|
|
|
** Engine & Tooling
|
|
- Integrated 2D/3D rendering system:
|
|
- Immediate-mode canvas-based 3D rendering with low-poly 5th-6th gen console aesthetics.
|
|
- 2D overlays styled after ImGui.
|
|
- [[https://www.libsdl.org/][SDL2]] backend for input, audio, and cross-platform compatibility.
|
|
- Tree-walk interpreter + stack-based bytecode VM:
|
|
- Compile bytecode to files for performance.
|
|
- REPL with hot-code reloading for rapid iteration.
|
|
- Emacs major mode included; Vim, VSCode, and Lite XL support planned.
|
|
|
|
** Language Design
|
|
- Dynamically typed with optional type hints in function signatures.
|
|
- Unified =real= type (=f64= by default) with =byte= for interop (u8, i32, f32, etc.).
|
|
- 3D math primitives: =vec=, =mat=, =quat=, and more.
|
|
- Strings with interpolation, =split=, =replace=, =trim=, etc.
|
|
- Error handling:
|
|
- Go-style explicit errors.
|
|
- Null coalescing (=??=) and null checks (=?.=).
|
|
- Lightweight coroutines with event-loop-driven multitasking.
|
|
- FFI via C-defined "native functions" (examples provided in VM).
|
|
|
|
** Modularity & Ecosystem
|
|
- Unified table type (like Lua) for lists, maps, and tuples.
|
|
- Standard library: math, networking, 3D rendering, minimal GUI.
|
|
- =use= keyword for modular code organization via file-based namespaces.
|
|
|
|
* Technical Details
|
|
|
|
** VM Architecture
|
|
- Stack-based bytecode interpreter written in C99.
|
|
- Portable to new systems, microcontrollers, and web via Emscripten.
|
|
|
|
** Memory Management
|
|
- Reference counting for globally scoped objects.
|
|
- =weak= keyword to avoid cyclical references.
|
|
- Arena allocators for short-lived, scoped memory (e.g., function-local objects).
|
|
|
|
** Rendering & I/O
|
|
- SDL2-based abstraction for input, audio, and rendering.
|
|
- Immediate-mode 3D canvas with 2D overlay support.
|
|
|
|
* Planned Projects
|
|
|
|
1. **Code Editor with Terminal Emulator**
|
|
- Built-in development tooling.
|
|
2. **3D Chat Room**
|
|
- Multiplayer cube avatars navigating a shared low-poly world.

|
* Roadmap
|
|
|
|
- [ ] MVP: Core VM, REPL, and SDL2 integration.
|
|
- [ ] 3D rendering pipeline + ImGui-style GUI.
|
|
- [ ] Standard library and FFI examples.
|
|
- [ ] Emacs/Vim tooling + website launch.
|
|
- [ ] Fixed point for numbers for microcontrollers/retro computers without fpu
|
|
- [ ] Custom renderer without SDL for portability
|
|
|
|
* Motivation
|
|
|
|
ZTL bridges retro-inspired creativity with modern portability for:
|
|
- Game jams (rapid prototyping + 3D engine).
|
|
- Indie games (5th/6th-gen aesthetics).
|
|
- Permacomputing (low-resource, sustainable code).
|
|
- Education (simple VM/language design).
