Cond Expr
CondExpr...
is an expression parser. You use it via the "expr" markup, thusly:
(:if expr equal {$var1} {$var2} xor equal {$var3} {$var4})
(:if expr ! equal 'carrot' {$var4})
Operations available are:
- and
- or
- xor
- &&
- ||
- !
I think you can also use parenthetical expressions like
(: if expr ({$bool1} or {$bool2}) and ({$bool3} or {$bool4}) :)
Usage examples here:
- Conditional Markup - The if directive allows portions of a page to be included or excluded from rendering
- Cookbook:JJSApprovePage -
