Xah Emacs Blog
A hole to fall in.
Update Highlights
- Programing language, regarding lisp cons.
- This is the final say.
- The common lispers, have always been, the most idiotic bunch, in the past 30 years as far as i get to know them.
- Lisp cons, to this day, is the most momfaaking idiotic concept in comp sci.
- It is lisp cons, that killed lisp. Except, clojure, which ditched cons entirely.
- Nobody the faak do linked list today.
- It is not in all other langs since y2k.
- Only the lisp fanatics, still like chew it like fine wine, thinking, how great it is or was.
- the way to fix the lisp cons, is to ban any list that is not a proper list.
- that should be done 30 years ago.
- but today, there is more reason to not use lisp list, even proper list, due to parallel computation.

- Emacs: Xah Fly Keys 📦
- major key reorg. removed most starting with C-x, and other change. see below.
- Removed most keys starting with C-x. Reason is when you do M-x for some rarely used command, the C-x binding shows in minibuffer in precedence over leader key sequence. This makes it harder to know the easier key.
- Removed many C- keys such as C-p for moving cursor right. They were there so that emacs default key users might use them. But those people are not likely to adopt Xah Fly Keys anyway. Beginners simply press arrow keys.
- Added some 10 plus keys for kmacro commands. These are almost never used but good to have keys for the handful advanced emacs users. Each now has a leader key sequence. The exact key is to be changed.

- Emacs: Xah Fly Keys 📦
- Major change. Removed
xah-fly-shared-map
. And xah-fly-key-map is now not declared obsolete. xah-fly-shared-map
was introduced by Will Dey (and Dan Langlois) in 2020-04-18 during the key engine rewrite usingset-transient-map
.- The idea of
xah-fly-shared-map
is that it serves as a parent of xah-fly-command-map and xah-fly-insert-map. - This allows setting control modifier combinations such as C-t also be part of Xah Fly Keys binding, thus is automatically unbound when the mode is turned off, as it should.
- I think it makes things more complicated than worth.
