## 1. 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](https://aleo.org/). If your goal is to build a user experience
|
|
on the web that is both truly personal and truly private, then we recommend downloading the [Aleo Studio IDE](https://aleo.studio/)
|
|
and checking out the [Aleo Package Manager](https://aleo.pm/).
|
|
|
|
## 2. Build Guide
|
|
|
|
### 2.1 Install Rust
|
|
|
|
We recommend installing Rust using [rustup](https://www.rustup.rs/). You can install `rustup` as follows:
|
|
|
|
- macOS or Linux:
|
|
```bash
|
|
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
|
|
```
|
|
|
|
- Windows (64-bit):
|
|
|
|
Download the [Windows 64-bit executable](https://win.rustup.rs/x86_64) and follow the on-screen instructions.
|
|
|
|
- Windows (32-bit):
|
|
|
|
Download the [Windows 32-bit executable](https://win.rustup.rs/i686) and follow the on-screen instructions.
|
|
|
|
### 2.2a Build from Crates.io
|
|
|
|
We recommend installing Leo this way. In your terminal, run:
|
|
|
|
```bash
|
|
cargo install leo-lang
|
|
```
|
|
|
|
Now to use Leo, in your terminal, run:
|
|
```bash
|
|
leo
|
|
```
|
|
|
|
### 2.2b Build from Source Code
|
|
|
|
Alternatively, you can install Leo by building from the source code as follows:
|
|
|
|
```bash
|
|
# Download the source code
|
|
git clone https://github.com/AleoHQ/leo
|
|
cd leo
|
|
|
|
# Build in release mode
|
|
$ cargo build --release
|
|
```
|
|
|
|
This will generate an executable under the `./target/release` directory. To run Leo, run the following command:
|
|
```bash
|
|
./target/release/leo
|
|
```
|
|
|
|
## 3. Quick Start
|
|
|
|
Use the Leo CLI to create a new project
|
|
|
|
```bash
|
|
# create a new `hello_world` Leo project
|
|
leo new hello_world
|
|
cd hello_world
|
|
|
|
# build & setup & prove & verify
|
|
leo run
|
|
```
|
|
|
|
The `leo new` command creates a new Leo project with a given name.
|
|
|
|
The `leo run` command will compile the main program, generate keys for a trusted setup, fetch inputs, generate a proof and verify it.
|
|
|
|
Congratulations! You've just run your first Leo program.
