I had to read through all of these to come up with repository descriptions, so here's some more ones i liked:
OSSP sugar -- The Markup Language With Invisible Syntactic Sugar
OSSP sugar is a markup language and corresponding processing tool for
writing technical documentation that uses a mostly invisible markup
language (so-called "syntactic sugar" in compiler construction folk
terminology).
bro WHAT are you TALKING about (this actually appears to be an early markdown/rST-style system: https://git.sr.ht/~nabijaczleweli/ossp-sugar/tree/5adc722e/item/srml2sxml#L10)
OSSP svs - Stupid/Silly/Simple Versioning System
its incredible what mfs did to themselves before they had git, also
case "$cmd" in
v|vi|vim | e|em|ema|emac|emacs )
always execs ${EDITOR-vi} (https://git.sr.ht/~nabijaczleweli/ossp-svs/tree/trunk/item/svs.sh)
OSSP val - Value Access
OSSP val is a flexible name to value mapping library for ISO-C
variables. It allows one to access ISO-C variables through name
strings, [...]
what the fuck is an "ISO C variable" (this is actually a std::map<string, any>, but not very good https://git.sr.ht/~nabijaczleweli/ossp-val/tree/trunk/item/val.h)
OSSP cfg is a ISO-C library for parsing arbitrary C/C++-style configuration files
...parsing what? this appears to actually be a grammar compiler, unclear how this is configuration-related https://git.sr.ht/~nabijaczleweli/ossp-cfg/tree/trunk/item/cfg.pod
