# zo programming language

> Turn your thoughts into type-safe software and Ui instantly.

A language to ship, run, and build native and web applications optimized for speed. zo is a feature-rich ecosystem focus on high-performance, simplicity and data-oriented.

## Get started
- [Initiation guide](https://zo.compilords.house/initiation): Multi-chapter tour — install, primitives, variables, strings, arrays, generics, concurrency
- One-line install: `curl --proto '=https' --tlsv1.2 -sSf https://zo.compilords.house/install.sh | sh`
- [Install script source](https://zo.compilords.house/install.sh)

## Documentation
- [Initiation](https://zo.compilords.house/initiation): Canonical language guide
- [News](https://zo.compilords.house/news): Releases, milestones, design notes
- [Full docs (LLM-formatted)](https://zo.compilords.house/docs/llms-full.txt): Aggregated docs for ingestion

## Source
- [Repository](https://github.com/invisageable/zo): Compiler source, dual-licensed Apache-2.0 OR MIT
- [Grammar (EBNF)](https://github.com/invisageable/zo/blob/main/crates/compiler/zo-notes/public/grammar/zo.ebnf): Formal language grammar
- [Benchmarks](https://github.com/invisageable/zo/tree/main/crates/compiler/zo-benches): Methodology and full numbers vs clang, rustc

## Tools
- [codelord](https://github.com/invisageable/codelord): Editor designed to disappear. Code your thoughts instantly
- [fret](https://github.com/invisageable/zo/blob/main/crates/packager/fret): Package manager. Zero-config. Built for speed
- [zo VS Code extension](https://github.com/invisageable/zo/tree/main/crates/compiler/zo-vscode): syntax highlighting

## Key concepts
- Execution-based compilation: semantic analysis is compile-time execution that produces SIR (typed semantic IR), not tree-walking + annotation
- Pipelines: synchronous AOT (`Parse → Tree → Execute → SIR → Codegen`) feeds asynchronous Copilord (insight engine)
- zsx (zo syntax extension): HTML-like template extension for unified UI — same syntax targets DOM and GPU
- Hindley-Milner type inference, monomorphization, type checking
- Optimization: constant folding, propagation, dead code elimination
- Structured concurrency: green + OS threads wrapped in nursery scopes; no leaked threads, no data races

## Performance
- Parse + tokenize: 10,000,000 LoC/s target
- Semantic analysis (Tree → SIR): 5,000,000 LoC/s target
- Codegen (SIR → ARM64): 5,000,000 LoC/s target
- Benchmarks: zo runs 2–5× faster than equivalent clang/rustc compiles on identical workloads
