示例1: transformAndSaveAst
function transformAndSaveAst(fullPath: string, ast: any, options: FableCompilerOptions, info: CompilationInfo) {
// resolve output paths
const outPath = getOutPath(fullPath, info) + ".js";
const jsPath = join(options.outDir, outPath);
const jsDir = Path.dirname(jsPath);
ensureDirExists(jsDir);
// set sourcemap paths
const code: string | undefined = undefined;
const babelOptions = Object.assign({}, options.babel) as Babel.TransformOptions;
if (babelOptions.sourceMaps) {
// code = fs.readFileSync(fullPath, "utf8");
const relPath = Path.relative(jsDir, fullPath);
babelOptions.sourceFileName = relPath.replace(/\\/g, "/");
babelOptions.sourceMapTarget = Path.basename(outPath);
}
babelOptions.plugins = (babelOptions.plugins || [])
