README

📝 Markdown Harvest

A Rust crate designed to extract, clean, and convert web content from URLs found in text messages into clean Markdown format. Originally created as an auxiliary component for Retrieval-Augmented Generation (RAG) solutions to process URLs submitted by users.

Overview

Markdown Harvest was initially developed as part of a Retrieval-Augmented Generation (RAG) system where users submit text containing URLs, and the system needs to extract meaningful content from those URLs for further analysis or processing. This crate handles the extraction, cleaning, and structuring of web content automatically.

🎯 Why Markdown Harvest?

🚀 Built for AI/RAG Systems: Specifically designed for content preprocessing in AI workflows
🧹 Smart Content Extraction: Removes ads, navigation, and irrelevant elements automatically
📝 Markdown Output: Clean, structured Markdown perfect for LLM processing
🔄 Batch Processing: Handle multiple URLs efficiently in a single operation
🛡️ Robust Error Handling: Gracefully handles network issues and invalid URLs

📚 Usage Examples

📝 Synchronous Processing (Traditional)

use markdown_harvest::{MarkdownHarvester, HttpConfig};

fn main() {
    let text = "Check out this article: https://example.com/article.html and this one too: https://news.site.com/story";
    
    // Use default configuration
    let config = HttpConfig::default();
    let results = MarkdownHarvester::get_hyperlinks_content(text.to_string(), config);
    
    for (url, content) in results {
        println!("URL: {}", url);
        println!("Markdown Content:\n{}", content);
        println!("---");
    }
}

⚡ Asynchronous Processing (High Performance)

use markdown_harvest::{MarkdownHarvester, HttpConfig};
use std::sync::{Arc, Mutex};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let text = "Check out: https://example.com and https://httpbin.org/json";
    let config = HttpConfig::builder().timeout(30000).build();
    
    // Collect results in a thread-safe vector
    let results = Arc::new(Mutex::new(Vec::new()));
    let results_clone = results.clone();
    
    let callback = move |url: Option<String>, content: Option<String>| {
        let results = results_clone.clone();
        async move {
            if let (Some(url), Some(content)) = (url, content) {
                let mut results = results.lock().unwrap();
                results.push((url, content));
                println!("✅ Processed URL with {} characters", content.len());
            }
        }
    };
    
    MarkdownHarvester::get_hyperlinks_content_async(text.to_string(), config, callback).await?;
    
    let final_results = results.lock().unwrap();
    println!("📊 Total URLs processed: {}", final_results.len());
    
    Ok(())
}

🔄 Real-time Processing with Immediate Output

use markdown_harvest::{MarkdownHarvester, HttpConfig};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let text = "Visit https://example.com for more info";
    let config = HttpConfig::default();
    
    // Process and display results immediately as they arrive
    let callback = |url: Option<String>, content: Option<String>| async move {
        match (url, content) {
            (Some(url), Some(content)) => {
                println!("🚀 Processed: {}", url);
                println!("📄 Content length: {} characters", content.len());
                // Save to database, send to API, etc.
            }
            (None, None) => {
                println!("ℹ️ No URLs found in the provided text");
            }
            _ => unreachable!(),
        }
    };
    
    MarkdownHarvester::get_hyperlinks_content_async(text.to_string(), config, callback).await?;
    
    Ok(())
}

💻 Interactive CLI Mode

The crate provides an interactive CLI mode for testing:

cargo run

Then enter text containing URLs when prompted.

🔧 Advanced HTTP Configuration

use markdown_harvest::{MarkdownHarvester, HttpConfig};

fn main() {
    let text = "Articles: https://site1.com and https://site2.com";
    
    // Custom HTTP configuration with Builder pattern
    let config = HttpConfig::builder()
        .timeout(10000)        // 10 second timeout
        .max_redirect(5)       // Allow up to 5 redirects
        .cookie_store(true)    // Enable cookie storage for sessions
        .build();
    
    let results = MarkdownHarvester::get_hyperlinks_content(text.to_string(), config);
    
    for (url, content) in results {
        println!("Processed: {}", url);
        println!("Content length: {} chars", content.len());
    }
}

🎯 Different Configuration Examples

use markdown_harvest::{MarkdownHarvester, HttpConfig};

// Quick timeout for fast responses only
let fast_config = HttpConfig::builder()
    .timeout(3000)  // 3 seconds
    .build();

// Conservative configuration for slow sites
let patient_config = HttpConfig::builder()
    .timeout(30000)     // 30 seconds
    .max_redirect(10)   // More redirects allowed
    .cookie_store(true) // Handle authentication
    .build();

// Use different configs for different scenarios
let urgent_text = "Breaking news: https://news-site.com/urgent";
let deep_text = "Research: https://academic-site.edu/paper";

let urgent_results = MarkdownHarvester::get_hyperlinks_content(urgent_text.to_string(), fast_config);
let research_results = MarkdownHarvester::get_hyperlinks_content(deep_text.to_string(), patient_config);

📦 Semantic Chunking for RAG Systems (chunks feature)

Feature gate: chunks - Enable with markdown-harvest = { version = "0.1.5", features = ["chunks"] }

The chunks feature provides semantic text splitting optimized for RAG (Retrieval-Augmented Generation) systems using MarkdownSplitter with intelligent boundary detection.

🔄 Synchronous Chunking

use markdown_harvest::{MarkdownHarvester, HttpConfig};

#[cfg(feature = "chunks")]
fn main() {
    let text = "Research these articles: https://example.com/article1 and https://example.com/article2";
    let config = HttpConfig::default();
    let chunk_size = 1000; // 1000 characters per chunk
    
    let results = MarkdownHarvester::get_hyperlinks_content_as_chunks(
        text.to_string(), 
        config, 
        chunk_size,
        Some(100) // 100 characters overlap for better context preservation
    );
    
    for (url, chunks) in results {
        println!("📄 URL: {}", url);
        println!("📦 Generated {} semantic chunks:", chunks.len());
        
        for (i, chunk) in chunks.iter().enumerate() {
            println!("  Chunk {}: {} chars", i + 1, chunk.len());
            println!("  Content: {}\n---", chunk.chars().take(100).collect::<String>());
        }
    }
}

⚡ Asynchronous Chunking

use markdown_harvest::{MarkdownHarvester, HttpConfig};
use std::sync::{Arc, Mutex};

#[cfg(feature = "chunks")]
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let text = "Process these for RAG: https://docs.example.com https://blog.example.com";
    let config = HttpConfig::builder()
        .timeout(15000)
        .build();
    let chunk_size = 800; // Optimal for embedding models
    
    // Real-time chunk processing for RAG pipeline
    let callback = |url: Option<String>, chunks: Option<Vec<String>>| async move {
        match (url, chunks) {
            (Some(url), Some(chunks)) => {
                println!("🔗 Processing {} chunks from: {}", chunks.len(), url);
                
                for (i, chunk) in chunks.iter().enumerate() {
                    println!("  📦 Chunk {}: {} chars", i + 1, chunk.len());
                    
                    // RAG Pipeline Integration:
                    // 1. Generate embeddings for this semantic chunk
                    // 2. Store in vector database with metadata
                    // 3. Index for semantic search
                    // 4. Preserve document context and structure
                }
            }
            (None, None) => {
                println!("ℹ️ No URLs found in text");
            }
            _ => unreachable!(),
        }
    };
    
    MarkdownHarvester::get_hyperlinks_content_as_chunks_async(
        text.to_string(),
        config,
        chunk_size,
        Some(80), // 80 characters overlap - optimal for embedding models
        callback
    ).await?;
    
    Ok(())
}

🧠 Semantic Chunking Benefits

The MarkdownSplitter uses intelligent semantic levels for optimal RAG performance:

📊 Heading Preservation: Keeps headers with their content sections
📝 Paragraph Integrity: Maintains paragraph boundaries and flow
📋 List Coherence: Preserves list items and hierarchical structure
💻 Code Block Unity: Keeps code blocks intact as single units
🔗 Link Context: Maintains inline formatting and link relationships
⚖️ Semantic Balance: Optimizes chunk size vs. content coherence

Chunk Size Recommendations for RAG:

Small Models: 400-800 characters
Medium Models: 800-1500 characters
Large Models: 1500-2500 characters

🔄 Chunk Overlap Examples

The chunk_overlap parameter enables context preservation between adjacent chunks:

use markdown_harvest::{MarkdownHarvester, HttpConfig};

#[cfg(feature = "chunks")]
fn main() {
    let text = "Process: https://example.com/documentation";
    let config = HttpConfig::default();
    
    // Without overlap - standard chunking
    let standard_chunks = MarkdownHarvester::get_hyperlinks_content_as_chunks(
        text.clone(), 
        config.clone(), 
        1000, 
        None  // No overlap
    );
    // Result: [Chunk1][Chunk2][Chunk3]
    
    // With overlap - better context preservation
    let overlap_chunks = MarkdownHarvester::get_hyperlinks_content_as_chunks(
        text, 
        config, 
        1000, 
        Some(200)  // 200 characters overlap
    );
    // Result: [Chunk1][Chunk1+2][Chunk2+3][Chunk3] (200 char overlap)
    
    println!("Standard chunks: {}", standard_chunks.len());
    println!("Overlap chunks: {}", overlap_chunks.len());
}

Overlap Size Recommendations:

Use Case	Chunk Size	Recommended Overlap	Overlap %
Small Embeddings	400-800	100-200 chars	25-50%
Medium Embeddings	800-1500	150-300 chars	15-20%
Large Embeddings	1500-2500	200-400 chars	10-15%
Code Documentation	1000-2000	200-500 chars	20-25%
Academic Papers	1500-3000	300-600 chars	20-25%

Benefits of Overlap:

🔗 Context Continuity: Important information doesn't get "cut" between chunks
📈 Improved Retrieval: Higher probability of finding relevant information
🧠 Better Embeddings: More coherent semantic representations
⚡ Flexible Tuning: Adjust overlap based on content type and model requirements

🤖 AI Integration Context

This crate was specifically designed to serve as a content extraction component in Retrieval-Augmented Generation (RAG) workflows where:

👥 Users submit messages containing URLs alongside other text
🧠 AI systems need structured content from those URLs for analysis
📝 Clean, readable Markdown is required preserving essential content and structure while removing HTML markup, scripts, ads, and links
🔄 Multiple URLs need processing in batch operations
🛡️ Reliability is crucial with proper error handling and fallbacks

The extracted content can then be fed into language models, search systems, or other AI components for further processing.

🎯 Perfect for RAG Systems

Vector Database Integration: Clean Markdown is ideal for embedding generation
Token Optimization: Removes unnecessary content to reduce token usage
Batch Processing: Handle multiple URLs from user queries efficiently
Content Quality: Preserves semantic structure while removing noise

⚙️ Markdown Transformation Details

The crate performs intelligent HTML to Markdown conversion that preserves essential formatting while removing clutter:

✅ Preserved Elements

Headers: <h1> → # Header, <h2> → ## Header
Emphasis: <strong> → **bold**, <em> → *italic*
Lists: <ul><li> → - item, <ol><li> → 1. item
Blockquotes: <blockquote> → > quote text
Scientific names: <i>Bertholletia excelsa</i> → *Bertholletia excelsa*

❌ Removed Elements

Links: [text](url) → text (keeps text, removes URL)
Images: <img> tags completely removed
Media: <iframe>, <video>, <audio> elements stripped
Navigation: <nav>, <header>, <footer>, <aside> sections
Metadata: Author bylines, publication dates, tag lists
Advertisements: Elements with ad-related classes or IDs

🧹 Text Cleanup

Normalizes excessive whitespace and line breaks
Removes photo captions and image attribution text
Filters out navigation phrases ("click here", "read more")
Eliminates code blocks and technical markup
Preserves paragraph structure and readability

📄 Empty or missing content
🚫 Server errors (404, 500, etc.)
🛡️ Blocked requests or rate limiting

🔄 Migration from v0.1.2

⚠️ Breaking Change: v0.1.3 introduces a breaking change in the API.

Before (v0.1.2)

use markdown_harvest::MarkdownHarvester;

let text = "Check https://example.com";
let results = MarkdownHarvester::get_hyperlinks_content(text.to_string());

After (v0.1.3)

use markdown_harvest::{MarkdownHarvester, HttpConfig};

let text = "Check https://example.com";
let config = HttpConfig::default(); // Add this line
let results = MarkdownHarvester::get_hyperlinks_content(text.to_string(), config); // Add config parameter

Quick Migration Tips

Import HttpConfig: Add HttpConfig to your use statement
Create config: Use HttpConfig::default() for same behavior as before
Pass config: Add the config as the second parameter to get_hyperlinks_content()

The change enables powerful new features like custom timeouts, redirect control, and cookie management while maintaining the same core functionality.
