How the function package-installed-p should behave on emacs startup if
some package is already installed? It seems that it returns nil for
installed package on emacs startup.
Here is the full .emacs file (used for this test):
(require 'package)
(message "**** auto-complete is installed: %s ****" (package-installed-p
'auto-complete))
auto-complete package is installed for this moument, but during emacs
sturtup *Messages* buffer shows:
**** auto-complete is installed: nil ****
But after sturtup the evaluation of the expression
(message "**** auto-complete is installed: %s ****" (package-installed-p
'auto-complete))
returns:
**** auto-complete is installed: t ****
But how it is possible to install just not already installed packages on
startup. For this moument all packages are re-downloaded and reinstalled
for me during every emacs startup.
In GNU Emacs 24.2.1 (i386-mingw-nt5.1.2600)
of 2012-08-29 on MARVIN
Windowing system distributor `Microsoft Corp.', version 5.1.2600

It needs package-initialize to have been run, which is only done after
your init file has been read, as documented eg in C-h v
package-enable-at-startup. Maybe you could run package-initialize
explicitly and set package-enable-at-startup to nil? Or use
after-init-hook?

IIUC rather than (require 'package) you need to (package-initialize).

Thank you a lot!
(package-initialize) works fine.
The issue should be closed.

I've changed package-installed-p to signal an error if called before
package-initialize. Thank you, closing,

Why make package-installed-p something different from featurep?

`featurep' typically indicates if a particular file has been loaded,
whereas `package-installed-p' indicates whether the package is available
(e.g. can be loaded).

Should it be `package-available-p'?

It's probably not worse, but I don't see why it would be better.

I guess it depends how clear the current name is.
It wasn't clear to me that "installed" means "installed in your system",
but maybe most people will understand it.

Yes, I think it is fairly logical, matching the
`package-install' command.
