示例1: resolve

	resolve(variable: Variable): string {

		const { name } = variable;

		if (name === 'SELECTION' || name === 'TM_SELECTED_TEXT') {
			let value = this._model.getValueInRange(this._selection) || undefined;
			if (value && this._selection.startLineNumber !== this._selection.endLineNumber) {
				// Selection is a multiline string which we indentation we now
				// need to adjust. We compare the indentation of this variable
				// with the indentation at the editor position and add potential
				// extra indentation to the value

				const line = this._model.getLineContent(this._selection.startLineNumber);
				const lineLeadingWhitespace = getLeadingWhitespace(line, 0, this._selection.startColumn - 1);

				let varLeadingWhitespace = lineLeadingWhitespace;
				variable.snippet.walk(marker => {
					if (marker === variable) {
						return false;
					}
					if (marker instanceof Text) {
						varLeadingWhitespace = getLeadingWhitespace(marker.value.split(/\r\n|\r|\n/).pop());
					}
					return true;
				});
				const whitespaceCommonLength = commonPrefixLength(varLeadingWhitespace, lineLeadingWhitespace);

				value = value.replace(
					/(\r\n|\r|\n)(.*)/g,
					(m, newline, rest) => `${newline}${varLeadingWhitespace.substr(whitespaceCommonLength)}${rest}`
				);
			}
			return value;

		} else if (name === 'TM_CURRENT_LINE') {
			return this._model.getLineContent(this._selection.positionLineNumber);

		} else if (name === 'TM_CURRENT_WORD') {
			const info = this._model.getWordAtPosition({
				lineNumber: this._selection.positionLineNumber,
				column: this._selection.positionColumn

		} else if (name === 'TM_LINE_INDEX') {

示例2: _trimEdit

	static _trimEdit(editRange: Range, editText: string, editForceMoveMarkers: boolean, model: editorCommon.ITokenizedModel): editorCommon.ISingleEditOperation {

		let currentText = model.getValueInRange(editRange);

		// Find the equal characters in the front
		let commonPrefixLength = strings.commonPrefixLength(editText, currentText);

		// If the two strings are identical, return no edit (no-op)
		if (commonPrefixLength === currentText.length && commonPrefixLength === editText.length) {
			return null;
		}

		if (commonPrefixLength > 0) {
			// Apply front trimming
			let newStartPosition = model.modifyPosition(editRange.getStartPosition(), commonPrefixLength);

			editText = editText.substring(commonPrefixLength);
			currentText = currentText.substr(commonPrefixLength);
		}

		// Find the equal characters in the rear
		let commonSuffixLength = strings.commonSuffixLength(editText, currentText);

		if (commonSuffixLength > 0) {
			// Apply rear trimming
			let newEndPosition = model.modifyPosition(editRange.getEndPosition(), -commonSuffixLength);
			editRange = new Range(editRange.startLineNumber, editRange.startColumn, newEndPosition.lineNumber, newEndPosition.column);
			editText = editText.substring(0, editText.length - commonSuffixLength);
