示例1: nbSegmentsPerLine
// returns the number of segments per line
function nbSegmentsPerLine(ctx: EmitterVisitorContext) {
const sm = ctx.toSourceMapGenerator('o.ts').toJSON() !;
const lines = sm.mappings.split(';');
return lines.map(l => {
const m = l.match(/,/g);
return m === null ? 1 : m.length + 1;
});
}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 generate unique argument names', () => {
const externalIds = new Array(10).fill(1).map(
