The :match_affix plugin allows changing the default prefix and suffix used for match patterns.
Roda's default behaviour for a match pattern like 'albums' is to use the pattern /\A\/(?:albums)(?=\/|\z)/.
This prefixes the pattern with / and suffixes it with (?=\/|\z). With the :match_affix plugin,
you can change the prefix and suffix to use.
So if you want to be explicit and require a leading / in patterns, you can set the prefix to "".
If you want to consume a trailing slash instead of leaving it, you can set the suffix to (\/|\z).
You set the prefix and suffix to use by passing arguments when loading the plugin:
plugin :match_affix, ""will load the plugin and use an empty prefix.
plugin :match_affix, "", /(\/|\z)/will use an empty prefix and change the suffix to consume a trailing slash.
plugin :match_affix, nil, /(\/|\z)/will not modify the prefix and will change the suffix to consume a trailing slash.
