Generate a slug (url-usable string) from a title or other string

sluggify.js

// convert a title to a slug
// 
// lowercase, replace ' ' by '-' and remove everything that is not alphanumeric, underscore or dash
var slug = title
  .toLowerCase()
  .replace(/ /g, '-')
  .replace(/--+/g, '-')
  .replace(/[^\w-]+/g, '')
  ;

sluggify.py

def generate_slug(title):
    slug = strip_accents(title)
    slug = slug.lower()
    slug = slug.strip().replace('.', '')
    slug = slug.replace('/', ' ')
    slug = slug.replace(' ', '-')
    slug = slug.replace('- ', '-')
    slug = slug.replace('--', '-')

import unicodedata
def strip_accents(s):
    s = s.decode('utf8')
    out = ''.join(c for c in unicodedata.normalize('NFD', s)
        if unicodedata.category(c) != 'Mn')
    return out.encode('utf8')

# usage
# generate_slug('My random title which can include accents and more ...')
