The abnf grammar is no longer stored in the leo repo. There is just a forwarding pointer to the grammars repo. This commit changes the link to go directly to the grammars repo. Signed-off-by: Eric McCarthy <7607035+bendyarm@users.noreply.github.com>

## 🍎 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/).
|
|
The language is currently in an alpha stage and is subject to breaking changes.
|
|
|
|
## ⚙️️ Build Guide
|
|
|
|
### 🦀 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.
|
|
|
|
### 🐙 Build from Source Code
|
|
|
|
We recommend installing Leo by building from the source code as follows:
|
|
|
|
```bash
|
|
# 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:
|
|
```bash
|
|
leo
|
|
```
|
|
|
|
## 🚀 Quick Start
|
|
|
|
Use the Leo CLI to create a new project
|
|
|
|
```bash
|
|
# create a new `hello-world` Leo project
|
|
leo new helloworld
|
|
cd helloworld
|
|
|
|
# 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 program into Aleo instructions and run it.
|
|
|
|
Congratulations! You've just run your first Leo program.
|
|
|
|
