Nachdem ich letztents ein Archiv meiner Mastodon Posts erstellt habe…

…sind diese nun auch Teil dieser Website. Das Archiv ist bisher noch nicht im Menü verkinkt, es ist unter /mastodon erreichbar.

Umsetzung

Die Umsetzung ist als Hugo Content Adapter recht einfach realisiert. Dieser liest das im letzten Vorgänger-Post erstellte Archiv (als JSON) ein und erstellt daraus Repräsentationen im Hugo-internen Seitenformat. Dazu muss im Hugo content Verzeichnis ein leeres Unterverzeichnis mit einer Datei namens _content.gotmpl angelegt werden. Das Beispiel nimmt dafür den Namen mastodon/_content.gotmpl an.

Am Anfang der Datei müssen lediglich die Quellldatei ($mastodonFile) und der Ordner, in dem die Medien abgelegt sind ($mastodonMediaPath), angegeben werden.
