clex_llm

clex_llm is a tool designed to generate Clex language expressions from input formats and constraints using a language model. It simplifies the process of creating complex test cases by converting human-readable descriptions into formal Clex grammar representations.

Features

• Automated Clex Generation: Automatically generate Clex expressions based on input formats and constraints.
• Integration with Google Generative AI: Utilizes Google Generative AI for generating accurate and efficient Clex expressions.

Getting Started

Prerequisites

Ensure you have Rust installed on your machine. You can install Rust using rustup.

Installation

Clone the repository and navigate to the clex_llm directory:

git clone https://github.com/rootCircle/cpast_mono.git
cd cpast_mono/clex_llm

Usage

To use clex_llm, you need to set up your Google Generative AI API key and run the tests:

GOOGLE_API_KEY="<api-key>" cargo test

Example

Here’s a complete example demonstrating how to use the clex_llm module:

use clex_llm::{create_generator, generate_clex_expression};

#[tokio::main]
async fn main() {
    let api_key = "your_google_api_key";
    let generator = create_generator(api_key).unwrap();

    let input_format = "The first line contains an integer K, followed by K lines each containing a floating-point number P.";
    let constraints = "1 ≤ K ≤ 50\n0.0 ≤ P ≤ 1000.0";

    match generate_clex_expression(&generator, input_format, constraints).await {
        Ok(expression) => println!("Generated Clex Expression: {}", expression),
        Err(e) => eprintln!("Error generating Clex expression: {}", e),
    }
}
