they/them
What sort of text processing? I rarely do this, so I usually just rely on things like sed, ed, sort, uniq, and other shell commands to handle this.
Nano, Micro, JOE, ee(1). Those are my suggestions.
I’ve used Vim, NeoVim, Micro, mg(1), JOE, and even MS Edit (both the original DOS version and the recent Rust clone). No matter how complex and tailored I wrote my config, though, the features I actually used were included in GNU nano and/or my command shell without any of the bugs, bloat, learning curve, or slop.
Using it as my default just makes sense.
