A simple Guile Scheme implementation of slugify, inspired by Django’s slugify.

Converts human-readable text into clean, lowercase, URL-safe identifiers.

• Converts Unicode or ASCII strings into slugs
• Optionally removes non-ASCII characters (NFKD + ASCII fallback)
• Collapses whitespace and separators into a single character
• Supports custom separator characters
• Trims leading/trailing dashes or underscores

Just copy slugify.scm into your project and (use-modules (slugify)).

If using as a library, ensure it's in your GUILE_LOAD_PATH:

export GUILE_LOAD_PATH="$GUILE_LOAD_PATH:$PWD"

(slugify str #:optional allow-unicode replacement)

(use-modules (slugify))

(slugify "Hello, World!")             ;; "hello-world"
(slugify "Café Déjà Vu" #f)           ;; "cafe-deja-vu"
(slugify "Café Déjà Vu" #t)           ;; "café-déjà-vu"
(slugify "foo bar" #t #\_)            ;; "foo_bar"
(slugify "你好")                       ;; "你好"
