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 isn’t, 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

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
------

1. Install FiraCode as per the [macOS installation instructions](https://github.com/tonsky/FiraCode/wiki/Installing#macos)
2. Open BBEdit preferences, Editor Defaults, assign Fira Code as the Default font


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
      (mapcar (lambda (regex-char-pair)
                `(,(car regex-char-pair)
                  (0 (prog1 ()
                       (compose-region (match-beginning 1)
                                       (match-end 1)
                                       ;; The first argument to concat is a string containing a literal tab
                                       ,(concat "   " (list (decode-char 'ucs (cadr regex-char-pair)))))))))
              '(("\\(www\\)"                   #Xe100)
                ("[^/]\\(\\*\\*\\)[^/]"        #Xe101)
