For BUG

I want to use global variable in a Pug template, specifically list the titles of all my posts (there are two of them):

p first line of the page

ul
    each i, j in site.posts
        - console.log(i, j, site.posts[i])
        li= po

p last line of the page

This code outputs the following HTML file

<p>first line of the page</p>
<ul>
    <li></li>
    <li></li>
</ul>
<p>last line of the page</p>

There are two empty <li></li>, which suggests that the iteration over the posts was successful.

The console output with debug enabled. Please note the console.log() output of mine, which shows that two indexes of the array were iterated over

I had the same problem with ESJ as the template engine.

When desperately analyzing the data provided by site, I ended up with the following workaround, but it looks very, very bad:

    each s in site
        if s.data && s.length > 0
            each p in s.data
                if p.title
                    li= p.title

I think this is a bug, or, if intended, documentation must be updated - the following works (please note the extra .data):

    each i in site.posts.data
        li= i.title

This is actually a documentation issue. site.posts is not iterable.
There is a discussion about it https://github.com/hexojs/site/issues/1489
I'm closing this issue. Please join the discussion there :)

Calling site.posts.data seems not recommended (see #1567) you should rather do site.posts.toArray(). See http://hexojs.github.io/warehouse/Query.html
