| Subject: | There is no way to negate a value for boolean tests |
I was trying to do something like <TMPL_IF EXPR="this && !that"> and
found I couldn't do it!
Here's a patch that adds a not() function that will negate its argument:
<TMPL_IF EXPR=<this && not(that)">
Adding a unary operator to the grammar to support !that is a bit more
involved than I'm ready for.
