what keyboard did emacs use in 1970s when emacs was TECO? Emacs Meta Key History
new version of emacs tutorial is out. Buy it! Not gonna send update to previous buyers, because last one is just a month ago.
Emacs: Jump to Previous Position
Major update.
by the way, a better way is to split buffer, do stuff, then move cursor back to the other pane, then unsplit.
emacs init: Intro
updated basic init file.
put it in your Emacs Init File, and life will be good.
emacs init: Set default font
added howto about setting up a font for Chinese characters and emoji.
reader macro and sigil
&option is just the syntax for rest parameters.
(:key1 value1 :key2 value2 ...) are syntax for key-and-value pairs.
@ and $ are just part of name that i use. syntax coloring of them is due to these starting symbol, in Emacs: Xah Elisp Mode π¦
The technical name for special symbol like
ampersan &
in
&option
[see Elisp: Function Parameters (optional, rest)]
and colon
:
in
(make-hash-table :test 'equal)
[see Elisp: Hash Table],
are called reader macro characters.
Emacs lisp manual does not have a page explaining
lisp reader macro.
Elisp does not support user defined reader macro, but has a page about
what reader do, on βRead and Printβ
Read and Print (ELISP Manual)
Clojure does not support user defined reader macro neither,
but clojure doc does talked about it and has a ton of it, see
Clojure: Variable Name Conventions (sigil. macro magic characters.)
About my use of @ and $, blood has been shed over that.
Misc Technical Essays and Non-Technical Essays on Emacs Lisp
some reorganization of index page at Emacs Misc. Index
in particular, created two navigation topic groups, one is Misc Technical Essays on Emacs Lisp see bottom of Elisp: Symbol vs String. Symbol Pollutes Symbol Table. and the other is Non-Technical Essays on Emacs Lisp, see bottom of Which Chapters of Elisp Manual to Read (2013)
There is quite a lot more to do about the reorganization of misc essays i've written in past 16 years. Will do in coming days.
