#+PROPERTY: header-args:emacs-lisp :tangle yes
|
||||
* My opinionated Emacs
|
||||
|
||||
* My Emacs' configuration
|
||||
|
||||
This is my Emacs configuration, it's written as [[https://www.wikiwand.com/en/Literate_programming][literate programming]]
|
||||
using [[https://orgmode.org/][org-mode]]'s Babel.
|
||||
All the settings are enclosed inside this single file named
|
||||
[[README.org]], the reason of this choice is that many services (like
|
||||
GitHub) automatically looks for these names.
|
||||
The configuration of different Emacs' aspects are kept divided in
|
||||
different paragraphs.
|
||||
|
||||
This file must be considered part of the Git repository to which it
|
||||
belongs and it may not work properly without the other files.
|
||||
Despite I mainly use [[https://nixos.org][NixOS]] I chose to keep my Emacs configuration
|
||||
detached from my Nix files, this way I should be able get my Emacs'
|
||||
settings in a non-Nix environment.
|
||||
|
||||
However the installing process of the required packages is not managed
|
||||
by this configuration; for example on my NixOS system I use the
|
||||
[[https://github.com/nix-community/emacs-overlay][emacs-overlay]] which automatically parses this file looking for the
|
||||
~(use-package <package>)~ declarations and then downloads and builds
|
||||
the latest versions from MELPA.
|
||||
I preferred to maintain this agnostic approach in order to don't make
|
||||
this already dense file even more complex.
|
||||
Indeed, as it's configured, ~use-package~ should ensure that the
|
||||
packages are installed, and if this is not the case it should install
|
||||
them.
|
||||
|
||||
I use [[https://github.com/ch11ng/exwm][EXWM]] (i.e. Emacs X Window Manager) but since I wanted to keep
|
||||
the possibility to use this configuration also on different systems
|
||||
(maybe without X.org) I tried to isolate its settings.
|
||||
So, even if I never tried, it should be easy to disable it without
|
||||
consequences.
|
||||
|
||||
** General settings
|
||||
This snippet contatins different things that I wasn't able to gather
|
||||
better.
|
||||
Hopefully, in a future, this section won't exist anymore.

** Theming
|
||||
I'm using the ~doom-one~ theme from the ~doom-themes~ package.
|
||||
In addition it's loaded the ~all-the-icons~ fonts and a special
|
||||
modeline from ~doom-modeline~.

** Evil
|
||||
In a future I think I'll try the Emacs keybindings, but for now I
|
||||
prefer the Vim keybindings, at least for the text editing.
|
||||
Since I use small keyboards I think it's better to use a modal editor,
|
||||
however for everything that is not text editing I use the normal Emacs
|
||||
keybindings.

** Helm

Unfortunately this is currently unmantained (there was only a

someone in the near future will pick up the project.
|

However this is really stable and I never had problems.
