geodate VS srgn

More than I can count, but here are the big ones:

http://moros.cc - A hobby operating system, with a shell, an editor, a lisp interpreter, and many other little things

https://geodate.org - A lunisolar calendar with decimal time (centidays and dimidays)

https://github.com/vinc/geodate - An implementation of the calendar + time

https://github.com/vinc/geocal - A tool to visualize the calendar + time

https://github.com/vinc/littlewing - A chess engine written in Rust (and another one before that in C++)

https://vinc.cc/software/ - A more complete list, on my personal website

I'm good at scratching my own itches but less good at finding projects that could be useful for other people.

It's currently whitelist-based [0]. The downside is larger (code) size. The upside is simplicity. I imagine a blacklist could also work well, at smaller size but with more preprocessing needed.

Wow! What a coincidence. Just the other day I finished "v1" of a similar tool: https://github.com/alexpovel/srgn , calling it a combination of tr/sed, ripgrep and tree-sitter.

I've spent a lot of time trying to find similar tools, and even list them in the README, but `AST-grep` did not come up! I was a bit confused, as I was sure such a thing must exist already. AST-grep looks much more capable and dynamic, great work.
