Hugo newbie here so sorry if question is silly and all. If my approach below is totally wrong I'd appreciate suggestions on how it could be fixed

Is there a particular reason why layouts/partials/head.html uses

<a href="{{ absLangURL "/" }}">{{ .Site.Title }}</a>

rather than just

<a href="{{ .Site.BaseURL }}">{{ .Site.Title }}</a>

?

The background for the question: I'd like my GitHub pages (at https://yugr.github.io) to provide several websites (currently it's just https://yugr.github.io/recovering-teamlead but I'd like to be able to add say https://yugr.github.io/pink-ponies-for-everyone in future). For this I have a separate subdirectory for each blog with custom baseURL attribute (I believe this approach is relatively common). E.g. for https://yugr.github.io/recovering-teamlead I set

baseURL = 'https://yugr.github.io/recovering-teamlead/'

in my hugo.toml.

Unfortunately absLangURL "/" evaluates to https://yugr.github.io (rather than https://yugr.github.io/recovering-teamlead/ as I would expect) which gives reader 404.

I believe same issue will apply to other calls to absURL.
