Subject: Support dot accessors on variables
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=bf331cafbadee278f302ad7622ea9db645eecdb7;p=thirdparty%2Fjinja.git

Support dot accessors on variables

This adds support for dot accessors on variables in such a way that
it is flexible enough to match the handling provided by the existing
template engine.
