Language switcher template code

support
1

Hello - I’ve implemented a language switch dropdown menu, with this code in my sidebar partial:

<ul id="dropdown1" class="dropdown-content">
 {{ $perma := .Permalink }}
 {{ with .Params.alternatelocales }}
 {{ range . }}
 {{ $thelocale := . }}
 {{ $currenturl := ( index $.Site.Data.translations $.Site.Params.locale ).languageurl }}
 {{ $targeturl := ( index $.Site.Data.translations $thelocale ).languageurl }}
 {{ $langurl := replace $perma $currenturl $targeturl }}
  <li><a href="{{ $langurl }}">{{ ( index $.Site.Data.translations $thelocale ).languagename }}</a></li>
 {{ end }}
 {{ end }}
</ul>

This works, to find in the .Permalink http://acme.com/thepath, the current url http://acme.com and replace it with http://acme.jp for example. It assumes the url path is the same, but in my case, that’s true.

With this, I just put the array of alternative languages available in my content.md file.

Later I’ll add a check whether the alternatelocale is in the frontmatter, and if not, don’t show the switcher.

I’m just wondering if there’s a more efficient or “better” way of doing this, in general.

Any comments appreciated.
Sincerely,
Rick
