What is this?
Without any internet access, you get to have this:
Installation
Make sure you also got the submodules checked out:
git submodule init
git submodule update
Then download a .slob file with the data you want. I use the Wikipedia one, from here:
https://ftp.halifax.rwth-aachen.de/aarddict/enwiki/enwiki20260401-slob/
There's a release per month, so choose what you want. There's also many other datasets you can choose from - see https://ftp.halifax.rwth-aachen.de/aarddict/ The enwiki ones contain the entirety of the text content in the English Wikipedia; and my Mathjax filter makes sure that the pages auto-render all mathematical notation.
Put the file in the same place as I did (/opt/aard.wikipedia/enwiki-20260401.slob) or update the SLOBBY_FILE
in the Makefile.
Usage can't get any simpler:
This will build a Docker container with both slobby and my Mathjax proxy filter; and then launch them both.
You can then visit http://localhost:8014 to access the end result.
Note that the docker image is "only" 247MB, which I suppose is an achievement these days; keep in mind
that the enwiki-20260401.slob file is 24GB, so we're only adding 1% extra :-)
Notes
Hope this helps someone! It's a Wikipedia that will still function, even when you don't have any Internet connectivity - giving you what matters the most: the text, and the math.
The bulk of the work was done by the slob/slobby guys. All I did was add a proxy in front, that extracts the math definitions from the "alt" field of non-inline math images, and uses Mathjax to render them.
Before, with just slobby:
After, over this mathjax_proxy.py:
