Conditionally show if collection has an odd number of entries?

Hi

How would I conditionally show something if a collection has an odd number of entries?

I've added {{ switch between='odd|even' }} to the collection loop, this adds a class of odd or even.

Can I use switch as part of last? I think I need something like, If last is odd then do this.

{{ collection:blog as="posts" }}
    <ul>
        {{ posts }}
        <li class="{{ switch between='odd|even' }}">{{ title }}</li>
        {{ /posts }}

        {{# SHOW IF LAST ENTRY IS AN ODD NUMBER #}}
        {{ if last }}
            <li>Call to action</li>
        {{ /if }}
    </ul>
{{ /collection:blog }}

For this, I would recommend checking if the total_results is divisible by two:

Regex or Runtime Antlers using modifiers:

{{ collection:blog as="posts" }}
<ul>
    {{ posts }}
    <li class="{{ switch between='odd|even' }}">{{ title }}</li>
    {{ /posts }}

    {{# SHOW IF LAST ENTRY IS AN ODD NUMBER #}}
    {{ if (total_results | %:2) != 0 }}
        <li>Call to action</li>
    {{ /if }}
</ul>
{{ /collection:blog }}

Excellent, that's a nice way of doing it. Thanks John.
