NAME ^

Template::Liquid::Tag::If - Basic If/Elsif/Else Construct

Description ^

If I need to describe if/else to you... Oy. if executes the statement once if and only if the condition is true. If the condition is false, the first elseif condition is evaluated. If that is also false it continues in the same pattern until we find a true condition or a fallback else tag.

Compound Inequalities

Solution supports compund inequalities. Try these...

    {% if some.value == 3 and some.string contains 'find me' %}
        Wow! It's a match...
    {% elseif some.value == 4 or 3 < some.value %}
        Wow! It's a... different... match...
    {% endif %}

Bugs ^

Liquid's (and by extension Template::Liquid's) treatment of compound inequalities is broken. For example...

    {% if 'This and that' contains 'that' and 1 == 3 %}

...would be parsed as if it were...

    if ( "'This" && ( "that'" =~ m[and] ) ) { ...

...but it should look like...

    if ( ( 'This and that' =~ m[that]) && ( 1 == 3 ) ) { ...

It's just... not pretty but I'll work on it. The actual problem is in Template::Liquid::Block if you feel like lending a hand. Wink, wink.

See Template::Liquid::Condition for a list of supported inequality types.
