Re: Closure book Hello World example

[Michael Bolin]

I don't have time to dig into this right now, but tools for inevitably evolve, which is why I listed the versions of the tools that I used in Chapter 1 (or maybe the introduction?). That said, I don't believe the current tools are all that different, so it's probably a very small tweak.

Hi,

I've been following along in the Closure book's Hello World example. When following the template portion of the example I don't arrive at the desired results.

my template:

{namespace example.templates}

/**

* @param greeting

* @param year

*/

{template .welcome}

<h1 id="greeting">{$greeting}</h1>

The year is {$year}.

{/template}

ran with:

java -jar ../closure-templates/build/SoyToJsSrcCompiler.jar --outputPathFormat hello.soy.js --shouldGenerateJsdoc --shouldProvideRequireSoyNamespaces hello.soy

creates hello.soy.js containing (notice the null|undefined in the second parameter and the missing var in the object):

// This file was automatically generated from hello.soy.

// Please don't edit this file by hand.

goog.provide('example.templates');

goog.require('soy');

goog.require('soydata');

/**

 * @param {Object.<string, *>=} opt_data

 * @param {(null|undefined)=} opt_ignored

 * @return {string}

 * @notypecheck

 */

example.templates.welcome = function(opt_data, opt_ignored) {

  return '\t<h1 id="greeting">' + soy.$$escapeHtml(opt_data.greeting) + '</h1>The year is ' + soy.$$escapeHtml(opt_data.year) + '.';

};

According to the book the second param and return should be:

* @param {soy.StringBuilder=} opt_sb

* @return {string|undefined}

No errors are thrown in cmd.

Thanks in advance for any help.

The closure template default mode is no longer to use string builder. You can switch it back but the new default generates smaller faster code.
