Here is an updated version, not with improved visuals:
[-- Attachment #2: selecting-read.el --]
[-- Type: application/emacs-lisp, Size: 12118 bytes --]
[-- Attachment #3: Type: text/plain, Size: 3832 bytes --]
For the most part, the suggestion is the same, I just added an
additional generic function
(selecting-read-flags object)
that returns a list of flags, to indicate if an object is selectable,
should be folded by default, etc.
As a demonstration, the option selecting-read-auto-narrow enabled a
behaviour that is similar to what selecting completion framework
provide.
I have also mentioned that a "translation function" could be written to
translate completing-read calls into selecting-read. Here is an example
that could be set to completing-read-function, even if it does not
implement the entire interface:
--8<---------------cut here---------------start------------->8---
(defun selecting-read-<-completing-read (prompt collection &optional
predicate
require-match
initial-input
_hist
default
_inherit-input-method)
"Translation interface for `completing-read' to `selecting-read'.
PROMPT, COLLECTION, PREDICATE, REQUIRE-MATCH, INITIAL-INPUT and
DEFAULT are all interpreted as by `completing-read'."
(or (selecting-read (all-completions "" collection predicate)
:must-select (not (memq require-match
'(confirm-after-completion
confirm
nil)))
:initial-query initial-input
:prompt prompt)
(cond ((listp default) (car default))
((null default) "")
(default))))
--8<---------------cut here---------------end--------------->8---
There are still issues, especially with large collections (try C-h o and
wait). When I get around to working on this again, I'll try to implement
the lazy selection generation, as mentioned before.
