For my package management, I prefer to use ~straight~ ([[https://github.com/raxod502/straight.el][Github]]). This is
due to its capacity of integrating nicely with ~use-package~, which is
also supported by ~general~ which I use for my keybindings (see below),
but also because with it I can specify where to retrieve packages that
are not on MELPA or ELPA but on Github and other online Git
repositories too.

First, let’s bootstrap straight.

Now, we can refresh our package list in order to be able to install
stuff.
#+begin_src emacs-lisp
(package-initialize)
(unless package-archive-contents
(package-refresh-contents))
;; Initialize use-package on non-Linux platforms
(unless (package-installed-p 'use-package)

#+end_src
(require 'use-package)
From time to time, I fork some packages either because I’m trying to
implement something new in said package, or because the package is
unmaintained and I want to continue developing it a bit more. Straight
provides a nice feature for using forks of a package with its ~:fork~
option. If set to ~t~, then straight will attempt to retrieve the
package with the same name but with a different username on the same
host. This username is retrieved through the following variable:
#+begin_src emacs-lisp
(setq straight-host-usernames
'((github . "Phundrak")
(gitlab . "Phundrak")))
#+end_src
The huge advantage of straight is it clones through git the packages
it installs. This means development can be done directly on the
downloaded package. However, Forge (a Magit extension for interacting
with websites such as Github, Gitlab, and such) interacts by default
with the forge described by the ~origin~ remote, which isn’t necessarily
the one I want Forge to interact with by default. Therefore, all
default remotes are named ~straight~ so it won’t collide with my regular
development flow.
#+begin_src emacs-lisp
(setq straight-vc-git-default-remote-name "straight")
#+end_src
We finally come to the ~use-package~ installation. This is done like so:
#+begin_src emacs-lisp
(straight-use-package '(use-package :build t))
(setq use-package-always-ensure t)
#+end_src
