It'd be nice if M-x apt-utils-show-package, when it prompts for a
package name, didn't build the list of possible names until you hit tab
or whatever to try to complete from among them. The apt-cache program,
or whatever builds the list, is very slow on my system and it's good to
get the prompt without doing that, since of course you can type a
package name without using the completions. The few lines below work
for me, using a completions handler function.
(defun apt-utils-show-package (&optional new-session)
"Show information for a Debian package.
A selection of known packages is presented. See `apt-utils-mode'
for more detailed help. If NEW-SESSION is non-nil, generate a
new `apt-utils-mode' buffer."
(interactive "P")
(let ((package (apt-utils-choose-package)))
(when (> (length package) 0)
(apt-utils-show-package-1 package t new-session))))
(defun apt-utils-choose-package ()
"Choose a Debian package name."
(let ((package
(and (eq major-mode 'apt-utils-mode)
(cadr (member 'apt-package
(text-properties-at (point)))))))
(when (not (stringp package))
(setq package nil))
(completing-read (if package
(format "Choose Debian package (%s): " package)
"Choose Debian package: ")
'apt-utils-choose-package-completion
nil t package)))
(defun apt-utils-choose-package-completion (str pred all)
"Apt package name completion handler, for `completing-read'."
