I've used mg and find it generally useful. It's my default editor pretty much everywhere.

However, the code is a mess, with deliberately cryptic identifiers (e.g., `w_doto` for `cursorOffset`), redundant functions (e.g., `vtputc()` is a strict subset of the behavior of `vtpute()`) and a bunch of other weird choices (e.g., deeply-baked assumptions that one byte == one char == one column, even thought Big5 and ShiftJIS were already a thing when it was written).

I tried adding UTF-8 support to mg a couple years ago and basically gave up.

I'll probably be an atto convert.

Well, sometimes we call the cursor "the dot."

Literally never heard that prior to hacking on the mg codebase.

Emacs called it “point” which is not as far. The cursor is just the visible widget.

also in sam and acme editors in plan9 os

In GNU Emacs, try running M-: (dot) RET.

I think this alias was an aid to porting Lisp from some other Emacs variant in the 80s that used "dot" instead of "point". Never figured out which. It isn't mg because mg doesn't run Lisp.

Also available for most linux distros as a package.

mg is nice, but I miss the colored text
