Installing
==========
Windows
-------
In the ttf folder, double-click each font file, click “Install font”; to install all at once, select all files, right-click, and choose “Install”
OR
Use https://chocolatey.org:
choco install firacode
macOS
-----
In the downloaded TTF folder:
1. Select all font files
2. Right click and select `Open` (alternatively `Open With Font Book`)
3. Select "Install Font"
OR
Use http://brew.sh:
`brew tap homebrew/cask-fonts`
`brew install font-fira-code`
Ubuntu Zesty (17.04), Debian Stretch (9) or newer
-------------------------------------------------
1. Make sure that the `universe` (for Ubuntu) or `contrib` (for Debian) repository is enabled (see https://askubuntu.com/questions/148638/how-do-i-enable-the-universe-repository or https://wiki.debian.org/SourcesList#Component)
2. Install `fonts-firacode` package either by executing `sudo apt install fonts-firacode` in the terminal or via GUI tool (like “Software Center”)

Linux Manual Installation
-------------------------
With most desktop-oriented distributions, double-clicking each font file in the ttf folder and selecting “Install font” should be enough. If it isnt, create and run `download_and_install.sh` script:
#!/usr/bin/env bash
fonts_dir="${HOME}/.local/share/fonts"
if [ ! -d "${fonts_dir}" ]; then
echo "mkdir -p $fonts_dir"
mkdir -p "${fonts_dir}"
else
echo "Found fonts dir $fonts_dir"
fi
for type in Bold Light Medium Regular Retina; do
file_path="${HOME}/.local/share/fonts/FiraCode-${type}.ttf"
file_url="https://github.com/tonsky/FiraCode/blob/master/distr/ttf/FiraCode-${type}.ttf?raw=true"
if [ ! -e "${file_path}" ]; then
echo "wget -O $file_path $file_url"
wget -O "${file_path}" "${file_url}"
else
echo "Found existing file $file_path"
fi;
done
echo "fc-cache -f"
fc-cache -f
More details: https://github.com/tonsky/FiraCode/issues/4
FreeBSD
-------
Using pkg(8):
pkg install firacode
OR
Using ports:
cd /usr/ports/x11-fonts/firacode && make install clean
Enabling ligatures
==================
Atom
----
To change your font to Fira Code, open Atom's preferences (`cmd + ,` on a Mac, `ctrl + ,` on PC), make sure the "Settings" tab is selected, or the "Editor" in Atom 1.10+, and scroll down to "Editor Settings". In the "Font Family" field, enter `Fira Code`.
If you wish to specify a font weight, for example, Light, use `Fira Code Light` as a font name (Windows) or `FiraCode-Light` (macOS).
Ligatures are enabled by default in Atom 1.9 and above.
VS Code
-------
To open the settings editor, first from the File menu choose Preferences, Settings or use keyboard shortcut `Ctrl + ,` (Windows) or `Cmd + ,` (macOS).
To enable FiraCode in the settings editor, under "Commonly Used", expand the "Text Editor" settings and then click on "Font". In the "Font Family" input box type `Fira Code`, replacing any content. Tick the check box "Enables/Disables font ligatures" under "Font Ligatures" to enable the special ligatures.
If you wish to specify a font weight, for example, Light, use `Fira Code Light` as a font name (Windows) or `FiraCode-Light` (macOS).
IntelliJ products
-----------------
1. Enable in Settings → Editor → Font → Enable Font Ligatures
2. Select `Fira Code` as "Primary font" under Settings → Editor → Font
Additionally, if a Color Scheme is selected:
3. Enable in Settings → Editor → Color Scheme → Color Scheme Font → Enable Font Ligatures
4. Select Fira Code as "Primary font" under Settings → Editor → Color Scheme → Color Scheme Font
BBEdit, TextWrangler
--------------------
Run in your terminal:
defaults write com.barebones.bbedit "EnableFontLigatures_Fira Code" -bool YES
Source: https://www.barebones.com/support/bbedit/ExpertPreferences.html
Brackets
--------
1. From the `View` menu choose `Themes....`
2. Paste `'Fira Code'`, at the beginning of `Font Family`
Emacs
-----
There are a few options when it comes down to using ligatures in
Emacs. They are listed in order of preferred to less-preferred. Pick one!
1. Using composition mode in Emacs Mac port
If you're using the latest Mac port of Emacs (https://bitbucket.org/mituharu/emacs-mac by Mitsuharu Yamamoto) for macOS, you can use:
(mac-auto-operator-composition-mode)
This is generally the easiest solution, but can only be used on macOS.
2. Using prettify-symbols
These instructions are pieced together by https://github.com/Triavanicus, taking some pieces from https://github.com/minad/hasklig-mode.
This method requires you to install the Fira Code Symbol font, made by https://github.com/siegebell:
https://github.com/tonsky/FiraCode/issues/211#issuecomment-239058632
(defun fira-code-mode--make-alist (list)
"Generate prettify-symbols alist from LIST."
(let ((idx -1))
(mapcar
(lambda (s)
(setq idx (1+ idx))
(let* ((code (+ #Xe100 idx))
(width (string-width s))
(prefix ())
(suffix '(?\s (Br . Br)))
(n 1))
(while (< n width)
(setq prefix (append prefix '(?\s (Br . Bl))))
(setq n (1+ n)))
(cons s (append prefix suffix (list (decode-char 'ucs code))))))
list)))
(defconst fira-code-mode--ligatures
'("www" "**" "***" "**/" "*>" "*/" "\\\\" "\\\\\\"
"{-" "[]" "::" ":::" ":=" "!!" "!=" "!==" "-}"
"--" "---" "-->" "->" "->>" "-<" "-<<" "-~"
"#{" "#[" "##" "###" "####" "#(" "#?" "#_" "#_("

"<~~" "</" "</>" "~@" "~-" "~=" "~>" "~~" "~~>" "%%"
"x" ":" "+" "+" "*"))
(defvar fira-code-mode--old-prettify-alist)
(defun fira-code-mode--enable ()
"Enable Fira Code ligatures in current buffer."
(setq-local fira-code-mode--old-prettify-alist prettify-symbols-alist)
(setq-local prettify-symbols-alist (append (fira-code-mode--make-alist fira-code-mode--ligatures) fira-code-mode--old-prettify-alist))
(prettify-symbols-mode t))
(defun fira-code-mode--disable ()
"Disable Fira Code ligatures in current buffer."
(setq-local prettify-symbols-alist fira-code-mode--old-prettify-alist)
(prettify-symbols-mode -1))
(define-minor-mode fira-code-mode
"Fira Code ligatures minor mode"
:lighter " Fira Code"
(setq-local prettify-symbols-unprettify-at-point 'right-edge)
(if fira-code-mode
(fira-code-mode--enable)
(fira-code-mode--disable)))
(defun fira-code-mode--setup ()
"Setup Fira Code Symbols"
(set-fontset-font t '(#Xe100 . #Xe16f) "Fira Code Symbol"))
(provide 'fira-code-mode)

3. Using composition char table
Thanks to https://github.com/seanfarley for putting this together; extended by https://github.com/jrblevin.
Put this lisp in your .emacs:
(when (window-system)
(set-frame-font "Fira Code"))
(let ((alist '((33 . ".\\(?:\\(?:==\\|!!\\)\\|[!=]\\)")
(35 . ".\\(?:###\\|##\\|_(\\|[#(?[_{]\\)")
(36 . ".\\(?:>\\)")
(37 . ".\\(?:\\(?:%%\\)\\|%\\)")
(38 . ".\\(?:\\(?:&&\\)\\|&\\)")
(42 . ".\\(?:\\(?:\\*\\*/\\)\\|\\(?:\\*[*/]\\)\\|[*/>]\\)")
(43 . ".\\(?:\\(?:\\+\\+\\)\\|[+>]\\)")
(45 . ".\\(?:\\(?:-[>-]\\|<<\\|>>\\)\\|[<>}~-]\\)")
(46 . ".\\(?:\\(?:\\.[.<]\\)\\|[.=-]\\)")
(47 . ".\\(?:\\(?:\\*\\*\\|//\\|==\\)\\|[*/=>]\\)")
(48 . ".\\(?:x[a-zA-Z]\\)")
(58 . ".\\(?:::\\|[:=]\\)")
(59 . ".\\(?:;;\\|;\\)")
(60 . ".\\(?:\\(?:!--\\)\\|\\(?:~~\\|->\\|\\$>\\|\\*>\\|\\+>\\|--\\|<[<=-]\\|=[<=>]\\||>\\)\\|[*$+~/<=>|-]\\)")
(61 . ".\\(?:\\(?:/=\\|:=\\|<<\\|=[=>]\\|>>\\)\\|[<=>~]\\)")
(62 . ".\\(?:\\(?:=>\\|>[=>-]\\)\\|[=>-]\\)")
(63 . ".\\(?:\\(\\?\\?\\)\\|[:=?]\\)")
(91 . ".\\(?:]\\)")
(92 . ".\\(?:\\(?:\\\\\\\\\\)\\|\\\\\\)")
(94 . ".\\(?:=\\)")
(119 . ".\\(?:ww\\)")
(123 . ".\\(?:-\\)")
(124 . ".\\(?:\\(?:|[=|]\\)\\|[=>|]\\)")
(126 . ".\\(?:~>\\|~~\\|[>=@~-]\\)")
)
))
(dolist (char-regexp alist)
(set-char-table-range composition-function-table (car char-regexp)
`([,(cdr char-regexp) 0 font-shape-gstring]))))
**Note!** If you get `error in process filter: Attempt to shape unibyte text`, check out https://github.com/tonsky/FiraCode/issues/42. Emacs Cider users may avoid this issue by commenting the following line from the above config:
;; (46 . ".\\(?:\\(?:\\.[.<]\\)\\|[.=-]\\)")
Char `45` is also known to have issues in macOS Mojave.
If you are having problems with helm you can disable ligatures in helm:
(add-hook 'helm-major-mode-hook
(lambda ()
(setq auto-composition-mode nil)))
4. Using font-lock keywords
If none of the above worked, you can try this method.
This method requires you to install the Fira Code Symbol font, made by https://github.com/siegebell:
https://github.com/tonsky/FiraCode/issues/211#issuecomment-239058632
;;; Fira code
;; This works when using emacs --daemon + emacsclient
(add-hook 'after-make-frame-functions (lambda (frame) (set-fontset-font t '(#Xe100 . #Xe16f) "Fira Code Symbol")))
;; This works when using emacs without server/client
(set-fontset-font t '(#Xe100 . #Xe16f) "Fira Code Symbol")
;; I haven't found one statement that makes both of the above situations work, so I use both for now
(defconst fira-code-font-lock-keywords-alist

`(,(car regex-char-pair)
