<pattern-input class="your-class-name"
               :regExp="setting.regExp"
               :replacement="setting.replacement"
               @input="handleInput"

Thought

~~I'm not sure is it necessary to emit all the input events. Now I only emit input and change events.~~

And I think the RegExp settings is not good enough, it's a bit awkward. Maybe I should match what I want instead of replacing what I don't want. But how ?
