As you know, both angular and twig has common control construction - double curly braces. How can I change default value of Angular?
I know that I can do it in Twig,
As mentioned in similar question about Django and AngularJS, trick with changing default symbols (in Twig or AngularJS) can provide incompatibility with third-party software, which will use these symbols. So best advice I found in google: https://groups.google.com/d/msg/symfony2/kyebufz4M00/8VhF1KWsSAEJ
TwigBundle does not provide a configuration for the lexer delimiters as changing them would forbid you to use any templates provided by shared bundles (including the exception templates provided by TwigBundle itself).
However, you could use the raw tag around your angular templates to avoid the pain of escaping all curly braces: http://twig.sensiolabs.org/doc/tags/raw.html -- Christophe | Stof
Tag was renamed to verbatim
