示例1: resolve

let value = this._model.getValueInRange(this._selection) || undefined;
if (value && this._selection.startLineNumber !== this._selection.endLineNumber) {

// 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;
}

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