require and the package management system

require and the package management system

[aidy lewis]

Emacs users,

I currently use Emacs 24 and its package management system.

However, my .emacs file is littered with 'require' statements

(require 'rainbow-delimiters)
(require 'auto-complete-config)

Am I correct to say, that 'require' is not needed in my config if I
use the package manager system?

Many Thanks

Aidy

It's possible. Many of the packages installed by the package manager
use magic 'autoload' comments that automatically export the most used
symbols into the global namespace so you can address them and have the
rest of the library required automatically.

But it's also possible that no such autoload statements were used and
thus you still need to require (or autoload yourself) the library so
you can use it. It really comes down to a per library evaluation.

I would say that requires are often not needed and the easiest way for
you to find out which ones truly are is to remove them all (on a clean
commit of your .emacs file!) and try launching emacs.

eval-after-load and autoload are just two of the many ways you can
make emacs start faster if you're requiring too much.

Not sure I got the point here, but require is the instruction to load
a specific module, so you can have installed several module that are
"sleeping" because not required any more.
