示例1: it
it('should map non template parts to the factory file', () => {
appDir['app.component.ts'] = createComponentSource(templateDecorator('Hello World!'));
const genFile = compileApp();
const genSource = toTypeScript(genFile);
const sourceMap = extractSourceMap(genSource) !;
expect(originalPositionFor(sourceMap, {line: 1, column: 0}))
.toEqual({line: 1, column: 0, source: ngFactoryPath});
});示例2: expectMap
// All lines / columns indexes are 0-based
// Note: source-map line indexes are 1-based, column 0-based
function expectMap(
ctx: EmitterVisitorContext, genLine: number, genCol: number, source: string | null = null,
srcLine: number | null = null, srcCol: number | null = null) {
const sm = ctx.toSourceMapGenerator('o.ts').toJSON() !;
const genPosition = {line: genLine + 1, column: genCol};
const origPosition = originalPositionFor(sm, genPosition);
expect(origPosition.source).toEqual(source);
expect(origPosition.line).toEqual(srcLine === null ? null : srcLine + 1);
expect(origPosition.column).toEqual(srcCol);
}示例3: it
it('should be able to shift the content', () => {
ctx.print(createSourceSpan(fileA, 0), 'fileA-0');
const sm = ctx.toSourceMapGenerator('o.ts', 10).toJSON() !;
expect(originalPositionFor(sm, {line: 11, column: 0})).toEqual({
line: 1,
column: 0,
source: 'a.js',
});
});示例4: it
it('should emit an inline source map', () => {
const source = new ParseSourceFile(';;;var', 'in.js');
const startLocation = new ParseLocation(source, 0, 0, 3);
const endLocation = new ParseLocation(source, 7, 0, 6);
