OK, so I am continuing working on this from Dec 5th, 2020
I thought I’d actually install Hugo and get it working locally before I attempt to upload it into Micro.blog. brew install hugo and you’re done, which is great.
Looking at hugo --help showed me that Hugo has a Jekyll import function.
Since I had those social posts that I eventually want to get into Mb, this ended up perfect. I ran hugo import jekyl PATH-TO-JEKYLL . to transform those posts into Hugo compatible files.
I forked the marfa theme and put it into the Hugo folder. Error about a missing custom_footer.html file. Pretty sure this is part of the default Mb themes, so I just created an empty one in partials, and the site built and served locally! Very fast compared to my Jekyll experience: 568 ms for 569 pages and 220 static files!
Looks like custom footer was the only one missing. I’ll keep track of edits to it on the Marfa Theme notes page.
Looking at Mb plugins. Found BigfootJS again via the Mb plugin for Bigfoot. Probably better for me to use on this site rather than the super custom margin / side notes.
