# Usage
Rust must be installed for compiling the code. The latest version is recommended. Installing `cargo` is also recommended.
1. Clone the repo
```
git clone https://github.com/shivrm/risp
```
GitHub also lets you download the source code [as a ZIP](https://github.com/shivrm/risp/archive/refs/heads/main.zip).
2. Navigate to project folder
```
cd risp
```
3. Build and run with cargo
- Run without any arguments to start the REPL. This lets you interactively run statements - one at a time.
```
cargo run
```
- To execute code from a file, give the file path as a command-line argument. Replace `` with the path to the file:
```
cargo run
```
- Giving `bench` as a command-line argument will benchmark the lexer. Note that this might be performance intensive.
```
cargo run bench
```
# Examples
See `scripts/example.risp` for an example RISP script. Run it with
```
cargo run scripts/example.risp
```
