Some code to make Fira Code work in Emacs

fira-code-emacs

Some code to make Fira Code 2.0 work in Emacs.

To install, first run make. Copy some or all of the files in modified to you ~/.fonts directory. Put fira-code.el and fira-code-data.el into your load-path, and ensure fira-code-mode is enabled for any buffers where you want ligatures. Set your default font to one of the Fira Emacs variants. If you want to see all the ligatures variant characters, open fira-code-data.el in Emacs.

To control which ligatures and alternative characters are used, set fira-code-enable-substitution-predicate and fira-code-compose-predicate. Refer to the default values for an example of how to write your own predicates.

fira-code-emacs's Issues

Strange behavior with the last commit!

Great job, congratulations.

In the last commit you get a strange behavior as you can see in the attached image.

In my configuration I have it like this:

(leaf pcache
  :straight t
  :init
  (setq pcache-directory (let ((dir (concat conf:cache-dir "pcache/")))
                           (make-directory dir t)
                           dir)))

(leaf unicode-fonts
  :straight t
  :init (unicode-fonts-setup))

(global-font-lock-mode 1)
(set-face-attribute 'default nil
                    :font "Fira Emacs Retina"
                    :height 115
                    :slant 'normal
                    :weight 'normal
                    :width 'normal)

(leaf fira-code
  :straight (fira-code
             :type git
             :host github
             :repo "johnw42/fira-code-emacs")
  :hook (prog-mode-hook . fira-code-mode))

Thanks

Can't get fira-code-mode to work

Wrong ligature mappings

Hi,

I've been using this package successfully since it's release without any issues. However, I just tried installing again on another system using a clean checkout of this repo and rerunning make to generate fira-code-data.el. This time, the ligatures are not correctly mapped/rendered. See for example the first few lines of the fira-code-data.el opened in emacs below

;; -*- coding: utf-8 -*-
(defconst fira-code--data
  '(["space.frac" " " "\xe100"]  ;   
    ["exclam_exclam.liga" "!!" "\xe101"]  ;   
    ["exclam_exclam_period.liga" "!!." "\xe102"]  ;   
    ["exclam_equal.liga" "!=" "\xe103"]  ;   
    ["exclam_equal_equal.liga" "!==" "\xe104"]  ;   
    ["numbersign_exclam.liga" "#!" "\xe105"]  ;   
    ["numbersign_numbersign.liga" "##" "\xe106"]  ;   
    ["numbersign_numbersign_numbersign.liga" "###" "\xe107"]  ;   
    ["numbersign_numbersign_numbersign_numbersign.liga" "####" "\xe108"]  ;   

Upgrade to v3

Fira Code v3 was released last week. Please upgrade to that version: https://github.com/tonsky/FiraCode/releases/tag/3

It should only require changing 2 to 3.

Making things work with Doom Emacs

Caution: Developer with no lisp experience coming in hot with probably incorrect yet well-intentioned thoughts

I had to remove the (load "fira-code-data") line from fira-code.el and load the files from my config.org like so:

  (load-file "/home/john/.config/doom/font-ligatures/ligature-font.el")
  (load-file "/home/john/.config/doom/font-ligatures/fira-code-data.el")
  (load-file "/home/john/.config/doom/font-ligatures/fira-code.el")

While I was there, I fixed some warnings on lines 72-80 (replacing t with _):

    (cond
     ;; Haskell-specific settings:
     ((derived-mode-p 'haskell-mode)
      (pcase input-string
        ("$" _)                         ; use alternate $
        ("/=" "!=")                     ; "not equal" is /=
        ("!=" nil)                      ; != is not special
        (_ default-enabled)))
     (_ default-enabled))))

After that, it works as expected, from what I can tell. Thanks for contributing this project :)

fira-code-mode working for all modes except Agda

Thanks for sharing fira-code-mode. I've installed it following the provided instructions and I found that it works beautifully in all modes except the one I'm most interested in (Agda mode). Below are two screenshots:

1. fundamental mode and fira-code-mode enabled, the ligature is shown correctly
2. agda mode and fira-code-mode enabled, the ligature is not shown (but in the mode line there's a ligature!)

I have no issues with fira-code-mode in other languages (C++, Haskell), so I suppose that fira-code-mode and agda-mode step onto each other in some way, but I have no idea where to look for the issue. Any clue that could point me in the right direction?

BTW, I'm on MacOS and use Emacs for MacOS.

How to use cascadia code support?

I saw there are cascadia-emacs-data.el file and Cascadia Emacs font.
but there's no cascadia-mode. If I use fira-code-mode, the ligature seems not correct.

ligature typo ?

Hi, do this one

fira-code-emacs/ligature-font.el

Line 69 in c3ea764

"geter_equal.ss02")))

should be greater instead of geter ?
