Filters (trait)

Overview:

Filters enables value transformation hooks identified by a name string.

Use the Filters trait when building classes that should expose overridable value pipelines via named filter hooks.

Public API:

• ::filter($names, callable $modder = null) registers one or more filters.
• ::filterSingle($name, callable $modder) replaces filters.
• ::filterRemove($name, callable $modder = null) removes filters.
• ::filterWith($names, $default, ...$args) applies the first available filter chain.

Example:

Filter::add('core.redirect', function ($url) {
  return rtrim($url, '/');
});
