Subject: Support filters being call chained
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1a776bf469ab7b6b9c88cbb848465500be742fd8;p=thirdparty%2Fjinja.git

Support filters being call chained

Previously filters were not treated the same as variable, as a
result it was not possible to call the result of a filter. Since
filters are treated as regular variable and therefore can be called
any number of times, this change was necessary to allow them to be
parsed the same way.
