Not exactly "experimental", considering the Unix heritage, but -- line editors. "I've seen [visual] editors like that, but I don't feel a need for them. I don't want to see the state of the file when I'm editing." -- Ken Thompson, on the superiority of ed to visual editors. Summarized by Peter Salus in A Quarter Century of UNIX (Addison-Wesley, 1994). Definitely a blast from the past, but I do think line editors may force one to write simpler programs -- or to think in smaller chunks, as opposed to (doom)scrolling or moving about incrementally on a large screen. Who knows, maybe the line editing approach is making a comeback of sorts, with people figuring out how to write code using tablets, smartphones, RasPi-based low-powered devices, etc. Maybe we will start re-thinking the (possible) mental benefits of smaller screens / viewing less l

ines of text or code at a time. Rob Pike's sam editor has an interesting command language. You're not limited to thinking in "lines" as in ed or sed; rather, the whole file is a giant string that you manipulate using regular expressions, external pipes, etc: http://doc.cat-v.org/bell_labs/sam_lang_tutorial/sam_tut.pdf In the light of the OP's question, I suppose Pike's "structural regular expressions" are the keyword here (explained in the above linked paper). It is a paradigm worth pointing out; also used later in screen-oriented editors like vis. sam's predecessor, qed, is also interesting, extremely powerful, but it seems to have a much steeper learning curve. I have used sam quite a bit, but not qed. https://github.com/phonologus/QED/raw/master/doc/qed-tutoria...
In Ask HN: More “experimental” UIs for editing/writing code?
How about a display that had a large e-ink screen plus a small LCD of maybe 2-4 lines at the bottom? Go old school for editing. Use something like TECO or ed or Rob Pike, David Tilbrook, Hugh Redelmeier and Tom Duff's Unix version of QED [1]. The small LCD is for seeing the command you are currently typing and a little command history. With those editors you entered editing commands but did not see the results until you asked for them. You'd tell the editor to show you the current line plus say 10 lines before and after. Then you'd give it commands to edit the current line, such as telling it to change the text "float" to "double", or telling it to insert a new line before the current line, and so on. When you had done enough changes that you needed to refresh your notion of the current state of the file, you'd ask it to show you again. E

ven the older generation, slower e-ink screens would be fast enough for that kind of work. Maybe instead of putting the small LCD display at the bottom of the e-ink screen, make it a separate unit that can attach to the e-ink screen or attach to the top of your keyboard or stand alone somewhere if you prefer.
