use-package is a configuration
management package for Emacs. Given that emacs users tend to install a lot of
packages as well as add customisations for it, an average
init.el can look like
a mess of macros and variable assignements.
use-package provides a macro that
can be used to classify and arrange configurations for a package under one macro
This results in a much cleaner configuration.
A simple declaration looks like this
It is possible to add configuration to this like this:
(use-package helm :config (helm-mode-1))
Need to add keybindings?
use-package has you covered:
(use-package helm :bind (("M-x" . helm-M-x)))
Want to hide minor modes that you know are always enabled? No problemo
(use-package helm :diminish helm-mode)
And this is my favourite one. Need to ensure a package is installed before you start using it?
(use-package helm :ensure t)
This is my favourite because this makes your Emacs configuration ready to use
on a new machine. Just clone your config to the new machine and startup Emacs.
That’s it, you’re done.
use-package will make sure the packages are installed.
Of course that also means
use-package needs to be installed beforehand. That
is pretty easy. All you need to do is add these lines:
(unless (package-installed-p 'use-package) (package-refresh-contents) (package-install 'use-package))
use-package you can create a sane version of your Emacs configuration
as well as make it shareable
