urlmatch - fnmatch for the web

This is a Ruby port of Jesse Pollak's Python urlmatch.

Use urlmatch to verify that URLs conform to certain patterns. The library and match patterns are based heavily on the Google Chrome Extension match patterns.

require 'urlmatch'

match_pattern = 'http://*.example.com/*'

Urlmatch.urlmatch(match_pattern, 'http://subdomain.example.com/') # true
Urlmatch.urlmatch(match_pattern, 'http://sub.subdomain.example.com/') # true

Urlmatch.urlmatch(match_pattern, 'https://example.com/') # false
Urlmatch.urlmatch(match_pattern, 'http://bad.com/') # false

The basic match pattern syntax is simple:

<url-pattern> := <scheme>://<host><path>
<scheme> := '*' | 'http' | 'https'
<host> := '*' | '*.' <any char except '/' and '*'>+
<path> := '/' <any chars>

• http://*/* - matches any URL that uses the http scheme
• https://*/* - matches any URL that uses the https scheme
• http://*/test* - matches any URL that uses the http scheme and has a path that starts with test
• *://test.com/* - matches any url with the domain test.com
• http://*.test.com - matches test.com and any subdomain of test.com
• http://test.com/foo/bar.html - matches the exact URL
