示例1: getHighlightedCode
function getHighlightedCode(lscAst: ILambdaScriptAstNode, lambdaScriptCode: string) {
const codeByLines = _str.lines(lambdaScriptCode),
colorActions = traverse(lscAst)
.reduce(function(colorActions: ILineColorAction[], astNode: ILambdaScriptAstNode) {
const color = colorMap[astNode.type];
if (color) {
const colorFn = chalk[color].bind(chalk),
locKey = alternateLocMap[astNode.type] || 'loc',
// I'm just using _.result to avoid TS7017
loc: ILoc = _.result(astNode, locKey);
/**
* Originally, I just colored as soon as I found a node. However, this does not work,
* because other coloring may have occurred on the line already, which will offset our
* column indices. And it is not sufficient just to drop all color from the line and
* see what the length difference is, because some of that color could be *after* our
* column indices and thus irrelevant. To solve this, we will gather all the colorings
* we want to do, and then apply them in sorted order. This makes the offset caclulation trivial.
