I did not know of a Java port, but this reminds me there is some kind of JavaScript-based environment for DOS that I see linked now and then (think it is bundled with FreeDOS?). Probably this one:
https://github.com/SuperIlu/DOjS
"DOjS is a JavaScript programming environment for systems running MS-DOS, FreeDOS or any DOS based Windows (like 95, 98, ME). It features an integrated editor, graphics & sound output, mouse/keyboard/joystick input and more"
Never tried it.
Not sure if they'll work on Alpine, but there's WordTsar (a Wordstar clone) and WordPerfect. Alternatively, you could run Word 5.5 in DOSBox.
Project mention: Show HN: Mutable.ai – Turn your codebase into a Wiki | news.ycombinator.com | 2024-01-08Nice! I’d be interested to see how it handles https://github.com/rosco-m68k/rosco_m68k , it’s a mixed software / hardware repo, with a lot of code in assembler and C (for an old platform). Might be a challenge?

* Good news: C can do compile time constant structs and array with deep self-references.
Yes, in C you can define and fully declare complex data structures that are accepted as compile-time constants, including pointers to parts of itself.
See "self-contained, statically allocated, totally const data structure with backward and forward references (pointers)?" for a previous example at https://stackoverflow.com/questions/47037701/can-c-syntax-de...
-----------------
I used this for a game on a retro machine where such a data structure avoids code which would have been several times (perhaps 10 times) bigger: https://github.com/cpcitor/color-flood-for-amstrad-cpc/blob/...
Here's another take showing two variant: where overall construct is an array then a struct: https://gist.github.com/fidergo-stephane-gourichon/792c194e1...
