Referencing Languages

Referencing some document in a particular language or the current document in another language is very easily achieved with Qgoda.

Since the asset.lingua variable is just a taxonomy, referencing a particular document in a certain language is just a matter of adding the language to the filter set you are using.

That means that language links are just a special case of Listings and Links. Read there for the full picture. This page just outlines the general idea.

Listings and Links for the Current Language (l-methods)

All methods of the Qgoda plug-in that take a set of filters as an argument have a corresponding version with the letter l prepended to the name that automatically adds a filter for the current language.

Example:

Creating a listing of posts for the tag JavaScript looks like this for a single-language site:

[% FOREACH post IN q.list('tags', ['contains', 'JavaScript']) %]
<a href="[% post.permalink %]">[% post.title | html %]</a>
[% END %]

For a multi-language site you would add one more filter:

[% FOREACH post IN q.list('lingua' = asset.lingua
                          'tags', ['contains', 'JavaScript']) %]
<a href="[% post.permalink %]">[% post.title | html %]</a>
[% END %]

And since this is such a common task, you can just use the method q.llist (think language list) instead that adds that filter automatically:

[% FOREACH post IN q.llist('tags', ['contains', 'JavaScript']) %]
<a href="[% post.permalink %]">[% post.title | html %]</a>
[% END %]

So in the end, a multi-language site requires just a single letter more of template code.

Language Switches

Another common tasks is to create a list of all language variants of a particular document. That can be achieved like this:

<ul>
[% FOREACH lingua IN config.linguas %]
  <li><a href="[% q.link(name=asset.name lingua=lingua) %]">[% lingua %]</a>
[% END %]
</ul>

This is using two filters. The first one is restricting the hits to those documents that have the same name property. The second one lingua=lingua further restricts to the language from the loop variable. Note that lingua=lingua is equivalent to 'lingua'=lingua; the left lingua is the name of the asset variable of the other document, the right one is the lopp variable.
