goog.string is not able to be used when soyutils.js is included in the same

  • 0

goog.string is not able to be used when soyutils.js is included in the same HTML file.

because in soyutils.js has its own goog.string that completely override goog.string <– goog.require(‘goog.string’).

<!DOCTYPE html>
<html>
<head>
    <title>codeBox</title>
    <script src="{{STATIC_URL}}closure-library/closure/goog/base.js"></script>
    <script>

    goog.require('goog.string');

    </script>

    <script src="{{STATIC_URL}}soyutils.js"></script>
</head>
<body>
    <script>
    console.log(goog.string.trim);

    </script>
</body>

(ignore {{STATIC_URL}} that is for Django Server)

console.log(goog.string.trim) will show you “undefined”.

That’s becuase goog.string is overridden by goog.string located in soyutils.js.

how can i get around this problem without compiling ? (when I compile all the files .. then it runs well)

    Instead of

    <script src="{{STATIC_URL}}soyutils.js"></script>

    use

    <script src="{{STATIC_URL}}soyutils_usegoog.js"></script>

    You can find soyutils_usegoog.js in the same directory as soyutils.js in the closure templates tarball.

    The problem arises because there are two versions of soyutils.

    1. soyutils.js is the version for non-closure users and includes just enough closure to make the JavaScript from SoyToJSCompiler work.
    2. soyutils_usegoog.js is the version that works with the closure library and closure compiler. It should not conflict with closure library.

    Closure Template JavaScript Usage explains:

    JavaScript code that’s generated by the template compiler depends on a number of utilities.

    Include one of these two utility files, depending on whether you’re already using the Closure Library:

    • javascript/soyutils.js
    • javascript/soyutils_usegoog.js

    These files are included in the tarball you can download from the Closure Templates downloads page.

    If your project already uses the Closure Library, use soyutils_usegoog.js, which is a much smaller file than soyutils.js.
