• your description: I write a transformer to transform export class A() { name: 'hhh'} =>class A() { name: 'hhh'}; __export__(FILENAME, 'A', A); there is a error when parsing export function, errr msg isast cannot be parsed cause replace export class is work when source is export function

// source code
export function myFunction() { 
    return 1; 
}

// transform script
function transform(fileInfo, api, options) {
  const $ = api.gogocode
  const source = fileInfo.source

  // return your transformed code here
  return $(source)
   .replace(`
        export class $_$1 { $_$2 }`,
        `
        class $_$1 { $_$2 }
        __export__('xxx', '${name}', ${name});
      `
    ).root().generate()
}

Got error:

/**

Error: replace failed: 
        class myFunction { return 1; }
        __export__('xxx', '', );
