What to use instead of Twig_Loader_String

Question

I see that the Twig_Loader_String class has been deprecated and will be removed in Twig 2.0. Also, the comments in the source indicate that it should \"NEVE

Answer 1

This actually seems to work as expected:

$tplName = uniqid( 'string_template_', true );
$env = clone $this->getTwig();
$env->setLoader( new \Twig_Loader_Array( [ $tplName => 'Hello, {{ name }}' ] ));
$html = new Response( $env->render( $tplName, [ 'name' => 'Bob' ] ));
$cacheName = $env->getCacheFilename( $tplName );
if( is_file( $cacheName ) )
{
  unlink( $cacheName );
}
echo $html; // Hello, Bob

I found the hints here: http://twig.sensiolabs.org/doc/recipes.html#using-different-template-sources.

Note that deleting the cache file would not be desirable if the template string came from a database or something similar. I use this functionality for rendering templates that are created dynamically and have very short life spans, usually when debugging and testing.
