🍎 Overview
Welcome to the Leo programming language.
Leo provides a high-level language that abstracts low-level cryptographic concepts and makes it easy to integrate private applications into your stack. Leo compiles to circuits making zero-knowledge proofs practical.
The syntax of Leo is influenced by traditional programming languages like JavaScript, Scala, and Rust, with a strong emphasis on readability and ease-of-use. Leo offers developers with tools to sanity check circuits including unit tests, integration tests, and console functions.
Leo is one part of a greater ecosystem for building private applications on Aleo. The language is currently in an alpha stage and is subject to breaking changes.
⚙️️ Build Guide
🦀 Install Rust
We recommend installing Rust using rustup. You can install rustup as follows:
-
macOS or Linux:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -
Windows (64-bit):
Download the Windows 64-bit executable and follow the on-screen instructions.
-
Windows (32-bit):
Download the Windows 32-bit executable and follow the on-screen instructions.
🐙 Build from Source Code
We recommend installing Leo by building from the source code as follows:
# Download the source code
git clone https://github.com/AleoHQ/leo
cd leo
# Install 'leo'
$ cargo install --path .
Now to use leo, in your terminal, run:
leo
🦁 Update from Leo
You can update Leo to the latest version using the following command:
leo update
Now to check the version of leo, in your terminal, run:
leo --version
📦 Download using Cargo
You can also install Leo directly from crates.io using cargo:
cargo install leo-lang
Now to use leo, in your terminal, run:
leo
🚀 Quick Start
Use the Leo CLI to create a new project
# create a new `hello-world` Leo project
leo new helloworld
cd helloworld
# build & setup & prove & verify
leo run main 0u32 1u32
The leo new command creates a new Leo project with a given name.
The leo run command will compile the program into Aleo instructions and run it.
Congratulations! You've just run your first Leo program.
