//! Basic usage example for OpenGrep
//! 
//! This example demonstrates how to use OpenGrep as a library
//! for programmatic code searching.

use opengrep::{Config, SearchEngine};
use std::path::PathBuf;
use tokio;

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    // Initialize logging
    opengrep::init_logging(1)?;

    config.output.show_ast_context = true;

    // Create search engine
    let engine = SearchEngine::new(config);
    
    // Search for "fn" in the current directory
    println!("Searching for 'fn' patterns...");
    let results = engine.search("fn", &[PathBuf::from(".")]).await?;
