Won't you only find packages that have the exact description "basic
interpreter" that way, or is the search cleverer than that?

Two Raspberry Pi related options:
- Gordon's RTB seems to have vanished from the repos but can be
downloaded here:
https://projects.drogon.net/rtb/rtb-download-and-install/ I just tried
it and it still works, and it does GPIO, but unfortunately for OP it
requires a graphical screen. (And to install libsdl-sound1.2 first, even
if you don't use sound.)
- Also graphical, harking back to the inspiration for the Raspberry Pi:
https://www.bbcbasic.co.uk/bbcsdl/

The only interpreter that I saw (in a web search) that does support
command line/batch mode is apparently bwbasic, which is in the standard
repo like you found.
