gap

you might want to bite off the gaps that are between other bites.

in this language, you can bite off "pasta", then "gang". but this time, you can leave a gap between them, if you want.

TRANSLATED:

it's easy. it's just a REGULAR EXPRESSION term that matches any number ofspaces or tabs.

class GapTerm extends RegExpTerm {
	constructor() {
		super(/[\s\t]+/)
	}
}

give it a name though. no one wants to see your filthy REGULAR EXPRESSION.

class GapTerm extends RegExpTerm {
	//...
	name() {
		return "gap"
	}
}

then use it in your list.

const listTerm = new ListTerm([
	new StringTerm("pasta"),
	new MaybeTerm(new GapTerm()),
	new StringTerm("gang"),
])

function translate(text) {
	return listTerm.translate(text)
}
