Url.appendSlug

Convert $pageTitle to a slug and append it to the URL path.

A “slug” is a token that is added to a URL to make it more human-readable and optimized for search engines.

See also String.toUrlSlug().

url'/blog'.appendSlug('Learn HTML in 33 Days!')
//= url'/blog/learn-html-in-33-days'

url'/article'.appendSlug('Turtles & Tide Pools')
//= url'/article/turtles-tide-pools'

Skip Words

The $skipWords argument takes a string containing a space-delimited list of words to exclude from the slug.

This will also filter out any duplicate words from the slug.

$pageTitle = '''
    THT News: The THT Festival Was a Success!
'''

url'/news'.appendSlug($pageTitle, 'a an the')
//= url'/news/tht-news-festival-was-success'

If $skipWords is :common, it will be set to a list of about 50 common English words (e.g. 'and', 'or', 'a', etc.) that will result in a cleaner, keyword-dense slug.

$pageTitle = '''
    This Man Watched 'Lord of the Rings' 3,000 Times
'''

url'/news'.appendSlug($pageTitle, ':common')
//= url'/news/man-watched-lord-rings-3000-times'
