use-package: load all defined packages

Question

I use use-package to defer package loading.
This is useful in emacs standalone mode.
I additional run emacs in daemon mode (emacs --daemon), then this behavior is not desired.

Is there a way to load all, in my init files defined, packages? In a way like this:

(if (daemonp)
    (foo-for-all-till-now-known-definitions-load-package))

Notes:
My init file is distributed over multiple files and directories.

I do not want to keep an extra list of packages which I have defined using use-package.
Me doing this, is not wanted:

(if (daemonp)
    (require 'org)
    (require 'paredit)
    ... )

Edit: it seems, that it is not clear what should be achieved by this. So here it is more clearly:

1. Packages should be loaded on demand only , when I am using emacs (without daemon or server mode). This is already working by using keywords :defer, :commands and :bind
   and
2. In server mode all packages should be loaded right at start of emacs --daemon, so that there is no waiting time later. This I hope to achieve by triggering a function, which triggers all packages (the ones defined using use-package) to be loaded.

Answer 1

Take a look at the customization options available for use-package. I think you can set use-package-always-demand based on how Emacs was started to get the behavior you want.

For example at the start of your init file (before any use-package forms) you could do something like:

(setq use-package-always-demand (daemonp))

Answer 2

You can either add :ensure t to each package you want to load from ELPA, or add (setq use-package-always-ensure t) to the beginning of your emacs config file and add :ensure nil to those few packages that you do not want from ELPA.

Packages are downloaded or upgraded at load time. When you want to install a new package, you should write the use-package sexp for it and eval it with C-x C-e to install and configure it at the same time.

Answer 3

I have not tested this, but according to the README there is a :demand feature that could do what you want:

You can override package deferral with the :demand keyword. Thus, even if you use :bind, using :demand will force loading to occur immediately and not establish an autoload for the bound key.
