lazybasic VS AdGuardMV3

I wrote a script that builds seamless background images out of sets of smaller images, kind of like contact sheets. This started for a comic book themed web site so that the background image could be a collage of comic covers with a special theme ( Christmas, celebration of a comic artist, ...etc. ) I am still cultivating the script so that it'll be friendly enough for public use. I'll place it on Github when that happens.

I like to tinker with my own compilers / interpreters. I had read an article recently about someone building an example Linux shell and I wanted to try a couple of ideas where I thought I'd take a different approach than the author. I ended up building a very, very tiny BASIC interpreter in C. My proof that the interpreter was "good enough" was whether or not I could write a script in the dialect of BASIC to display the lyrics to the song "The Twelve Days of Christmas."

For-profit content blockers have teams of paid developers working on this (for examples see https://gitlab.com/groups/eyeo/adblockplus/abc/-/issues/?sort=created_date&state=all&first_page_size=20, https://gitlab.com/groups/adblockinc/-/issues/?sort=created_date&state=all&label_name%5B%5D=manifest%20v3&first_page_size=20, https://github.com/AdguardTeam/AdGuardMV3/issues), and I also see the need for not trivial infrastructure to manage patching the filter lists, something which is beyond what I can provide.

This is what AdGuard MV3 is doing in a content script to keep alive the service worker:
