期望合并 registerHoverProvider 实现

[xiezhongfu]

已经支持了

• completionItems
• references
• definitions

worker 里已经支持了实体识别，可以增加下 Hover 了

[xiezhongfu]

看代码已经记 TODO 了。赞👍

预计什么时候能提供使用呢？

import { getWordAtText } from 'monaco-editor/esm/vs/editor/common/core/wordHelper';

export class HoverAdapter<T extends BaseSQLWorker> implements languages.HoverProvider {
	constructor(
		private readonly _worker: WorkerAccessor<T>,
		private readonly _defaults: LanguageServiceDefaults
	) {}

	provideHover(
		model: editor.IReadOnlyModel,
		position: Position,
		_token: CancellationToken,
		_context: languages.HoverContext<languages.Hover>
	): languages.ProviderResult<languages.Hover> {
		return this._worker(model.uri)
			.then((worker) => {
				let code = model?.getValue() || '';
				if (typeof this._defaults.preprocessCode === 'function') {
					code = this._defaults.preprocessCode(code);
				}
				return worker.getAllEntities(model?.getValue());
			})
			.then((entities) => {
				// const word = model.getWordAtPosition(position);
				const wordPattern = /\S+/;
				const lineContent = model.getLineContent(position.lineNumber);
				const word = getWordAtText(position.column, wordPattern, lineContent, 0);

				const curEntity = entities?.find((entity: EntityContext) => {
					const entityPosition = entity.position;
					if (
						entityPosition.startColumn === word?.startColumn &&
						entityPosition.endColumn === word?.endColumn &&
						entityPosition.line === position.lineNumber
					) {
						return entity;
					}
					return null;
				});
				console.log(111111, word, entities, curEntity);

				if (!curEntity) return null;

				return {
					contents: [new MarkdownString('哈哈哈哈')],
					range: new monaco.Range(
						position.lineNumber,
						curEntity.position.startColumn,
						position.lineNumber,
						curEntity.position.endColumn
					)
				};
			});
	}
}

大概11月会出个版本支持 Hover 特性
