((if either (|a) (|b) (|first result) (|second result)))
This helper template is designed to be used in other templates. It can help editors create template code that is more self documenting. A major advantage of using this template over using the construct ((#if:(({1|))}(({2|))} |…))
is that if the first parameter is not empty then the second parameter is not evaluated.
The "or" in the "a or b" above is inclusive: if both a and b are true, the template will return the first result.
This template can also be used to replace the construct ((#if:a |true |((#if:b |true |false))))
(i.e. "if a, then true; else if b, then true; else false").
Code | Result |
---|---|
((if either |a |b |true |false)) | true |
((if either |a | |true |false)) | true |
((if either | |b |true |false)) | true |
((if either | | |true |false)) | false |
