Hi Peter,
I'm not opposed to something like the above, but it only delays the
pain of building the package lists until the package name is entered.
However, I notice at least two problems with the patch as it stands:
(1) Entering an invalid package name for which there is a valid
completion, e.g., M-x apt-utils-show-package RET foo RET results in
a message to rebuild the package lists.
(2) If the package lists become outdated (maybe an `apt-get update'
has been run; simulate by touching apt-utils-timestamped-file,
/var/cache/apt/pkgcache.bin), then apt-utils-show-package leads to
an error like:
Debugger entered--Lisp error: (error "Command attempted to use minibuffer
while in minibuffer")
yes-or-no-p("APT package lists may be out of date. Update them? ")
(if apt-utils-automatic-update-asked nil (setq
apt-utils-automatic-update-asked t) (yes-or-no-p "APT package lists may be out
of date. Update them? "))
(unless apt-utils-automatic-update-asked (setq
apt-utils-automatic-update-asked t) (yes-or-no-p "APT package lists may be out
of date. Update them? "))
(cond ((eq apt-utils-automatic-update t)) ((eq apt-utils-automatic-update
...) (unless apt-utils-automatic-update-asked ... ...)))
(and (apt-utils-packages-needs-update) apt-utils-automatic-update (cond
(...) (... ...)))
(cond ((null apt-utils-package-list-built)
(apt-utils-build-package-list)) ((and ... apt-utils-automatic-update ...)
(apt-utils-build-package-list t)))
apt-utils-check-package-lists()
Thanks,
Matt
