示例1: compareAnything

export function fallbackCompare<T>(itemA: T, itemB: T, query: IPreparedQuery, accessor: IItemAccessor<T>): number {

	// check for label + description length and prefer shorter
	const labelA = accessor.getItemLabel(itemA);
	const labelB = accessor.getItemLabel(itemB);

	const descriptionA = accessor.getItemDescription(itemA);
	const descriptionB = accessor.getItemDescription(itemB);

	const labelDescriptionALength = labelA.length + (descriptionA ? descriptionA.length : 0);
	const labelDescriptionBLength = labelB.length + (descriptionB ? descriptionB.length : 0);

	if (labelDescriptionALength !== labelDescriptionBLength) {
		return labelDescriptionALength - labelDescriptionBLength;
	}

	// check for path length and prefer shorter
	const pathA = accessor.getItemPath(itemA);
	const pathB = accessor.getItemPath(itemB);

	if (pathA && pathB && pathA.length !== pathB.length) {
		return pathA.length - pathB.length;
	}

	// 7.) finally we have equal scores and equal length, we fallback to comparer

	// compare by label
	if (labelA !== labelB) {
		return compareAnything(labelA, labelB, query.value);
	}

	// compare by description
	if (descriptionA && descriptionB && descriptionA !== descriptionB) {
		return compareAnything(descriptionA, descriptionB, query.value);
	}

	// compare by path
	if (pathA && pathB && pathA !== pathB) {
		return compareAnything(pathA, pathB, query.value);
	}

	// equal
	return 0;
}

示例2: scoreItem

export function compareItemsByScore<T>(itemA: T, itemB: T, query: string, accessor: IItemAccessor<T>, cache: ScorerCache): number {
	const scoreA = scoreItem(itemA, query, accessor, cache).score;
	const scoreB = scoreItem(itemB, query, accessor, cache).score;

	// 1.) check for identity matches
	if (scoreA === PATH_IDENTITY_SCORE || scoreB === PATH_IDENTITY_SCORE) {
		if (scoreA !== scoreB) {
			return scoreA === PATH_IDENTITY_SCORE ? -1 : 1;
		}
	}

	// 2.) check for label prefix matches
	if (scoreA === LABEL_PREFIX_SCORE || scoreB === LABEL_PREFIX_SCORE) {
		if (scoreA !== scoreB) {
			return scoreA === LABEL_PREFIX_SCORE ? -1 : 1;
		}

		const labelA = accessor.getItemLabel(itemA);
		const labelB = accessor.getItemLabel(itemB);

		// prefer shorter names when both match on label prefix
		if (labelA.length !== labelB.length) {
			return labelA.length - labelB.length;
		}
	}

	// 3.) check for camelcase matches
	if (scoreA === LABEL_CAMELCASE_SCORE || scoreB === LABEL_CAMELCASE_SCORE) {
		if (scoreA !== scoreB) {
			return scoreA === LABEL_CAMELCASE_SCORE ? -1 : 1;
		}

		const labelA = accessor.getItemLabel(itemA);
		const labelB = accessor.getItemLabel(itemB);

		// prefer shorter names when both match on label camelcase
		if (labelA.length !== labelB.length) {
			return labelA.length - labelB.length;
		}
	}

	// 4.) check for label scores
	if (scoreA > LABEL_SCORE_THRESHOLD || scoreB > LABEL_SCORE_THRESHOLD) {
		if (scoreB < LABEL_SCORE_THRESHOLD) {
			return -1;
		}

		if (scoreA < LABEL_SCORE_THRESHOLD) {
			return 1;
		}
	}

	// 5.) check for path scores
	if (scoreA !== scoreB) {
		return scoreA > scoreB ? -1 : 1;
	}

	// 6.) at this point, scores are identical for both items so we start to sort by length

	// check for label + description length and prefer shorter
	const labelA = accessor.getItemLabel(itemA);
	const labelB = accessor.getItemLabel(itemB);

	const descriptionA = accessor.getItemDescription(itemA);
	const descriptionB = accessor.getItemDescription(itemB);

	const labelDescriptionALength = labelA.length + (descriptionA ? descriptionA.length : 0);
	const labelDescriptionBLength = labelB.length + (descriptionB ? descriptionB.length : 0);

	if (labelDescriptionALength !== labelDescriptionBLength) {
		return labelDescriptionALength - labelDescriptionBLength;
	}

	// check for path length and prefer shorter
	const pathA = accessor.getItemPath(itemA);
	const pathB = accessor.getItemPath(itemB);

	if (pathA && pathB && pathA.length !== pathB.length) {
		return pathA.length - pathB.length;
	}

	// 7.) finally we have equal scores and equal length, we fallback to comparer

	// compare by label
	if (labelA !== labelB) {
		return compareAnything(labelA, labelB, query);
	}

	// compare by description
	if (descriptionA && descriptionB && descriptionA !== descriptionB) {
		return compareAnything(descriptionA, descriptionB, query);
	}

	// compare by path
	if (pathA && pathB && pathA !== pathB) {
		return compareAnything(pathA, pathB, query);
	}

	// equal
	return 0;
