URL Slug Generation

Generate URL-friendly slugs from titles.

Basic Slug

#![allow(unused)]
fn main() {
use rok_utils::slug;

fn basic_slug(title: &str) -> String {
    slug(title)
}

assert_eq!(basic_slug("Hello World!"), "hello-world");
assert_eq!(basic_slug("O'Reilly's Guide"), "oreillys-guide");
}

Custom Slug

#![allow(unused)]
fn main() {
use rok_utils::slug;

fn underscore_slug(title: &str) -> String {
    slug(title, '_')
}

assert_eq!(underscore_slug("Hello World!"), "hello_world");
}

Advanced Slug with Fluent Builder

#![allow(unused)]
fn main() {
use rok_utils::str::Str;

fn advanced_slug(title: &str) -> String {
    Str::of(title)
        .trim()
        .lower()
        .replace("'", "")
        .replace("&", " and ")
        .replace("_", "-")
        .squish()
        .pipe(|s| slug(&s, '-'))
        .value()
}

assert_eq!(advanced_slug("  Hello World & Friends!  "), "hello-world-and-friends");
assert_eq!(advanced_slug("O'Reilly's Guide"), "oreillys-guide");
}

Complete Example

#![allow(unused)]
fn main() {
use rok_utils::str::Str;

fn generate_post_slug(title: &str, id: u64) -> String {
    let slug = Str::of(title)
        .trim()
        .lower()
        .replace("'", "")
        .replace("\"", "")
        .replace(" ", "-")
        .replace("--", "-")
        .when(|s| s.value().ends_with("-"), |s| {
            // Remove trailing dash
            s.pipe(|v| v.trim_end_matches('-').to_string())
        })
        .value();

    format!("{}-{}", id, slug)
}

assert_eq!(generate_post_slug("My Blog Post!", 123), "123-my-blog-post");
}
