@whenis/booking

Booking-domain plugin for whenis.

A worked example of the plugin API — adds rules, lexicon entries, and an enricher specific to hospitality / booking assistants while keeping the core parser domain-neutral.

What it adds

| Pattern | Produces | | ------------------------------------ | ------------------------------------------------------------------- | | на N ночей / днів | duration IR with nights = N | | впродовж N днів, у найближчі N днів | window IR (start = ref, end = ref + N − 1) | | наступні вихідні / ці вихідні | range IR for Saturday–Sunday with correct week selection | | після свят, на свята | fuzzy IR with reason: 'holiday_ref' | | Enricher: mostlyPastEnricher | Adds metadata.suggest_next_month = true when the referenced month is ≥ 75 % elapsed |

Install

pnpm add @whenis/core @whenis/locale-uk @whenis/booking

Usage

import { createParser } from '@whenis/core';
import { uk } from '@whenis/locale-uk';
import { booking } from '@whenis/booking';

const parser = createParser({
  locales: [uk],
  plugins: [booking],
  options: { preferFuture: true },
});
const ref = new Date('2026-05-28');

parser.parse('на 3 ночі',       { reference: ref }).matches[0].candidates[0];
// → { type: 'duration', nights: 3, confidence: 1 }

parser.parse('впродовж 7 днів', { reference: ref }).matches[0].candidates[0];
// → { type: 'window', start: '2026-05-28', end: '2026-06-03', confidence: 1 }

parser.parse('після свят',      { reference: ref }).matches[0].candidates[0];
// → { type: 'fuzzy', reason: 'holiday_ref', confidence: 0.3,
//     metadata: { suggest_next_month: true } }
