About Zirco

Zirco is an unstable work-in-progress compiled programming language focusing on its clean, expressive syntax without sacrificing clarity: no hidden memory allocations, no macros, just fast, explicit code.

It started out as (and still is) a hobby project for me to learn more about the world of compiler development, so there are no real promises for Zirco's real production usability. However, it also serves as a well-implemented reference for designing a compiler.

Toolchain Installation via Zircon

Zirco can be installed via the Zircon toolchain installer. For more information, visit the Zircon GitHub repository.

If you aim to contribute to the Zirco compiler itself, please follow the instructions below.

Getting Started

New to Zirco? Check out the Zirco Book for step-by-step instructions on:

• Installing the compiler
• Writing and compiling your first program
• Troubleshooting common issues

Quick Start

For experienced developers who want to get running quickly:

1. Install prerequisites:

   # Rust toolchain (if not already installed)
   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
   
   # LLVM 22 with Polly + other dependencies (Ubuntu/Debian)
   sudo apt-get update
   sudo apt-get install -y llvm-22 llvm-22-dev libpolly-22-dev clang-22 build-essential libssl-dev pkg-config libzstd-dev

2. Clone and build:

   git clone https://github.com/zirco-lang/zrc
   cd zrc
   cargo build

3. Install system-wide (optional):

   cargo install --path compiler/zrc

4. Compile your first program:

   # Create hello.zr with your favorite editor, then:
   zrc -o hello.o hello.zr
   clang -o hello hello.o -lc
   ./hello

Language Specification

For a comprehensive guide to the Zirco language syntax, semantics, and behavior, see the Language Reference.

Usage

If you are directly invoking the compiler with cargo, replace zrc with cargo run -- in the below commands.

You can compile a single Zirco file to a .o object with zrc -o main.o main.zr. Otherwise, zrc main.zr will emit LLVM IR. This is soon to change.

For more usage help, refer to zrc --help.

A Note on Stability

So that Zirco can continue to evolve at a rapid pace, there are NO STABILITY GUARENTEES on the current version of Zirco and zrc.

All internal compiler APIs are VERY unstable and if you integrate them with your own tooling builds may fail if you update zrc. Zirco code may change semantics or fail to build on a different zrc version.
