示例1: BuildJS

// BuildJS builds the js file and returns the content.
// goPkgPath must be a package path eg. github.com/influx6/haiku-examples/app
func BuildJS(jsession *JSSession, goPkgPath, name string, js, jsmap *bytes.Buffer) error {

	session, options := jsession.Session, jsession.Option

	//get the build path
	buildpkg, err := build.Import(goPkgPath, 0, session.InstallSuffix(), options.BuildTags)

	if err != nil {
		return err
	}

	if buildpkg.Name != "main" {
		return ErrNotMain
	}

	//build the package data for building
	// pkg := &build.PackageData{Package: buildpkg}

	//build the package using the sessios
	if err = session.BuildPackage(buildpkg); err != nil {
		return err
	}

	//build up the source map also
	smfilter := &compiler.SourceMapFilter{Writer: js}
	smsrc := &sourcemap.Map{File: name + ".js"}
	smfilter.MappingCallback = build.NewMappingCallback(smsrc, options.GOROOT, options.GOPATH)
	deps, err := compiler.ImportDependencies(buildpkg.Archive, session.ImportContext.Import)

	if err != nil {
		return err
	}

	err = compiler.WriteProgramCode(deps, smfilter)

	smsrc.WriteTo(jsmap)
	js.WriteString("//# sourceMappingURL=" + name + ".map.js\n")

	return nil
}
