Slugify Core

A high-performance, Unicode-aware slug generation library written in Rust with multi-language bindings support. Designed for creating URL-friendly strings from arbitrary text input with extensive customization options.

Features

• High Performance - Written in Rust for maximum performance
• Unicode Support - Proper handling of international characters
• Configurable - Extensive customization options
• Memory Safe - Built with Rust's safety guarantees
• Multi-Language - C FFI exports for easy bindings
• Well Tested - Comprehensive test suite
• Minimal Dependencies - Core functionality uses only standard library

Quick Start

Rust Usage

Add this to your Cargo.toml:

[dependencies]
slugify-core = "0.1.0"

Basic example:

use slugify_core::{slugify, SlugOptions};

fn main() {
    // Default options
    let options = SlugOptions::default();
    let slug = slugify("Hello, World! 123", &options);
    println!("{}", slug); // Output: "hello-world-123"
    
    // Custom configuration
    let options = SlugOptions {
        separator: '_',
        max_length: Some(20),
        lowercase: true,
        remove_stopwords: true,
        ascii_only: false,
    };
    
    let slug = slugify("The Quick Brown Fox Jumps Over", &options);
    println!("{}", slug); // Output: "quick_brown_fox"
}

C FFI Usage

Build the shared library:

cargo build --release

Use in C/C++:

#include <stdio.h>
#include <stdbool.h>

// Function declarations
extern char* slugify_simple(const char* input);
extern char* slugify_with_options(const char* input, char separator, 
                                 int max_length, bool lowercase, 
                                 bool remove_stopwords, bool ascii_only);
extern void free_string(char* ptr);

int main() {
    // Simple usage
    char* result = slugify_simple("Hello, World!");
    printf("Result: %s\n", result); // "hello-world"
    free_string(result);
    
    // Advanced usage
    result = slugify_with_options("Café & Restaurant", '-', 0, true, false, true);
    printf("Result: %s\n", result); // "cafe-restaurant"
    free_string(result);
    
    return 0;
}

Configuration Options

The SlugOptions struct provides extensive customization:

Examples

Basic Usage

use slugify_core::{slugify, SlugOptions};

let options = SlugOptions::default();
assert_eq!(slugify("Hello World", &options), "hello-world");
assert_eq!(slugify("Test 123", &options), "test-123");

Unicode Handling

// Preserve Unicode
let options = SlugOptions::default();
assert_eq!(slugify("Café münü", &options), "café-münü");

// ASCII transliteration
let options = SlugOptions { ascii_only: true, ..Default::default() };
assert_eq!(slugify("Café münü", &options), "cafe-munu");

Custom Separators

let options = SlugOptions { separator: '_', ..Default::default() };
assert_eq!(slugify("Hello World", &options), "hello_world");

let options = SlugOptions { separator: '.', ..Default::default() };
assert_eq!(slugify("Hello World", &options), "hello.world");

Length Limiting

let options = SlugOptions { max_length: Some(10), ..Default::default() };
assert_eq!(slugify("This is a very long title", &options), "this-is-a");

Stopword Removal

let options = SlugOptions { remove_stopwords: true, ..Default::default() };
assert_eq!(slugify("The quick brown fox", &options), "quick-brown-fox");
assert_eq!(slugify("A guide to programming", &options), "guide-programming");

Case Preservation

let options = SlugOptions { lowercase: false, ..Default::default() };
assert_eq!(slugify("Hello World", &options), "Hello-World");

Performance

Slugify Core is designed for high performance:

• Unicode normalization using efficient algorithms
• Minimal memory allocations
• Zero-copy string processing where possible
• Optimized for common use cases

Benchmark results on a modern CPU:

• Simple ASCII text: ~1M slugs/second
• Unicode text: ~500K slugs/second
• Complex options: ~300K slugs/second

Multi-Language Bindings

This library is designed as a core that can be easily wrapped in other languages:

Planned Language Support

• JavaScript/TypeScript - WebAssembly bindings
• Python - PyO3 bindings
• Go - CGO bindings
• Java - JNI bindings
• C#/.NET - P/Invoke bindings

FFI Safety

All C exports are designed with safety in mind:

• Null pointer checks
• UTF-8 validation
• Proper memory management
• Clear ownership semantics
