|
Unified system font across Emacs. |
||||
|
|
||||
|
* Setup |
||||
|
|
||||
|
Install the required ~firacode~[fn:1] font before loading the module: |
||||
|
|
||||
|
#+begin_src shell |
||||
|
RUN apt install -y fonts-firacode |
||||
|
#+end_src |
||||
|
|
||||
|
* Config |
||||
|
|
||||
|
Write out the value of ~dotfiles/font~ to all of the available font faces supported by Emacs. By default, this uses ~firacode~[fn:1] for its readability and ligature support. All of the heights are configured to ~dotfiles/font-size~ by default, with further configuration based on the given size possible. |
||||
|
|
||||
|
#+begin_src emacs-lisp |
||||
|
(set-face-attribute 'default nil :font dotfiles/font :height dotfiles/font-size) |
||||
|
(set-face-attribute 'fixed-pitch nil :font dotfiles/font :height dotfiles/font-size) |
||||
|
(set-face-attribute 'variable-pitch nil :font dotfiles/font :height dotfiles/font-size) |
||||
|
#+end_src |
||||
|
|
||||
|
** Icons |
||||
|
|
||||
|
Emacs feels more modern with prioritized icon fonts, available in the ~all-the-icons~[fn:2] package. This makes navigation and visually parsing directories much faster, given that the file types are quickly identified by their corresponding icons. |
||||
|
|
||||
|
#+begin_src emacs-lisp |
||||
|
(use-package all-the-icons) |
||||
|
#+end_src |
||||
|
|
||||
|
Integration with the built-in ~dired~ package is available in the ~all-the-icons-dired~[fn:3] package. |
||||
|
|
||||
|
#+begin_src emacs-lisp |
||||
|
(use-package all-the-icons-dired |
||||
|
:hook (dired-mode . all-the-icons-dired-mode)) |
||||
|
#+end_src |
||||
|
|
||||
|
** Emojis |
||||
|
|
||||
|
It's finally here, first class support for Emojis in Emacs via the ~emacs-emojify~[fn:4] package. Have we finally gone too far? |
||||
|
|
||||
|
#+begin_src emacs-lisp |
||||
|
(use-package emojify |
||||
|
:when (window-system) |
||||
|
:hook (after-init . global-emojify-mode)) |
||||
|
#+end_src |
||||
|
|
||||
|
** Symbols |
||||
|
|
||||
|
Programming buffers can be made prettier with ~pretty-mode~[fn:5], this is complimentary to ~prettify-symbols-mode~[fn:6], a built-in package containing similar (but lacking) functionality. |
||||
|
|
||||
|
#+begin_src emacs-lisp |
||||
|
(use-package pretty-mode |
||||
|
:hook (python-mode . turn-on-pretty-mode)) |
||||
|
#+end_src |
||||
|
|
||||
|
** Ligatures |
||||
|
|
||||
|
Enable ~firacode~[fn:1] font ligatures with the ~fira-code-mode~[fn:7] package. Only perform this action when ~firacode~[fn:1] is the current font, and Emacs isn't running on the TTY. |
||||
|
|
||||
|
#+begin_src emacs-lisp |
||||
|
(use-package fira-code-mode |
||||
|
:when (and (window-system) |
||||
|
(equal dotfiles/font "Fira Code")) |
||||
|
:hook (prog-mode org-mode)) |
||||
|
#+end_src |
||||
|
|
||||
|
** Parenthesis |
||||
|
|
||||
|
Colourize nested parenthesis with ~rainbow-delimeters~[fn:4], a mandatory life-jacked to keep you from drowning in the sea of them in Lisp. |
||||
|
|
||||
|
#+begin_src emacs-lisp |
||||
|
(use-package rainbow-delimiters |
||||
|
:hook (prog-mode . rainbow-delimiters-mode)) |
||||
|
#+end_src |
||||
|
|
||||
|
** Text scaling |
||||
|
|
||||
|
Define a transient keybinding for scaling the text. One caveat to this, it only works when Emacs is running as a GUI application, and has no effect in the terminal. |
||||
|
|
||||
|
#+begin_src emacs-lisp |
||||
|
(defhydra hydra-text-scale (:timeout 4) |
||||
|
"Scale" |
||||
|
("j" text-scale-increase "Increase") |
||||
|
("k" text-scale-decrease "Decrease") |
||||
|
("f" nil "Finished" :exit t)) |
||||
|
#+end_src |
||||
|
|
||||
|
* Shortcuts |
||||
|
|
||||
|
Scale the text inside of buffers using the custom transient binding, behind =SPC t f=: |
||||
|
|
||||
|
+ Increase with =j= |
||||
|
+ Decrease with =k= |
||||
|
+ Finish with =f= |
||||
|
|
||||
|
#+begin_src emacs-lisp |
||||
|
(dotfiles/leader |
||||
|
"tf" '(hydra-text-scale/body :which-key "Font")) |
||||
|
#+end_src |
||||
