@cks@mastodon.social it's not _super_ actively maintained¹ but it's probably worth including busybox vi in that set of implementations just due to sheer ubiquity. People definitely use it even if it's not due to preference. And incidentally, I recently ran across two articles specifically about nvi: - https://mattwidmann.net/notes/the-nvi-text-editor/ - just a brief interesting intro - https://git.sr.ht/~r1w1s1/code-notes/blob/main/notes/NVI_Editor_Guide.txt - a surprisingly insightful architectural review of nvi's implementation choices. I learned lots! ¹: https://git.busybox.net/busybox/log/editors/vi.c
