feature: configure display of language names in languange switcher

[mayuxi]

Hi!

A little suggestion. Now Ananke uses {{ .Lang }} as language link in layouts/partials/i18nlist.html, which makes language switcher links like that:

en pt-BR he ru

I suggest using .Site.Language.LanguageName instead, so the user can customize the language names in his config file. For example, it could be full names (English, Português, Русский), or even flag emojis (🇬🇧 🇧🇷 🇷🇺).

Sorry, I'm new to Hugo and Ananke, here is my suggested code for layouts/partials/i18nlist.html:

before

<a class="hover-white no-underline white-90" href="{{ .RelPermalink }}">{{ .Lang }}</a>

after

<a class="hover-white no-underline white-90" href="{{ .RelPermalink }}">{{ .Site.Language.LanguageName | default .Lang }}</a>

I agree; this should be a configuration option. For the time being, you can override the theme file by adding a copy to your own repository under layouts/partials/i18nlist.html and adding your changes there.
