It still seems inconsistent to me.
I am finding myself writing this in order to group related code.
(cond
((eq action 'metadata)
(make-local-variable 'completion-extra-properties)
(setq completion-extra-properties
(plist-put 'completion-extra-properties :exit-function
(lambda (comp status)
(when (cadr (assoc (car (last (split-string comp "[.]" t)))
python-module--completion-table))
(minibuffer-message "package")))))
'(metadata
(annotation-function
. (lambda (comp)
(when (cadr (assoc comp python-module--completion-table))
" <P>")))))
.......)
Otherwise I'd have to go to completing-read, xxxxx-completion-at-point
and the like to install the exit-function on each one of them. This is
repetitive and ugly.
I was hoping I could just write
(cond
((eq action 'metadata)
'(metadata
(annotation-function
. (lambda (comp)
(when (cadr (assoc comp python-module--completion-table))
" <P>")))
(exit-function
. (lambda (comp status)
(when (cadr (assoc (car (last (split-string comp "[.]" t)))
python-module--completion-table))
(minibuffer-message "package"))))))
.......)
Looks like with some change to completion--done we can have this. What
do you think?
