Fira Code: monospaced font with programming ligatures
Download Fira Code v1.000
Problem
Programmers use a lot of symbols, often encoded with several characters. For human brain sequences like ->
, <=
or :=
are single logical token, even if they take two or three places on the screen. Your eye spends non-zero amount of energy to scan, parse and join multiple characters into a single logical one. Ideally, all programming languages should be designed with full-fledged Unicode symbols for operators, but that’s not the case yet.
Solution
Fira Code is a Fira Mono font extended with a set of ligatures for common programming multi-character combinations. This is just a font rendering feature: underlying code remains ASCII-compatible. This helps to read and understand code faster. For some frequent sequences like ..
or //
ligatures allow us to correct spacing.
Editor support
Do not work:
- SublimeText (vote here)
- Intellij Idea (vote here), including everything built on top of it (PhpStorm, PyCharm, RubyMine, WebStorm, AppCode, CLion, ReSharper)
- iTerm 2 (feature request)
- OS X Terminal.app
- Emacs (workaround)
- gVim, MacVim
- Eclipse (Mac and Win, vote here)
- Notepad++
- Kate, Konsole, KWrite in KDE 4
- Xamarin Studio/Monodevelop
Do work:
- Atom (since 1.1, add
atom-text-editor { text-rendering:optimizeLegibility }
to the stylesheet) - Xcode (with this plugin)
- Visual Studio
- TextMate 2
- Coda 2
- Eclipse (Linux)
- QtCreator
- LightTable (instructions)
- BBEdit — enter this command in a terminal to enable ligatures:
defaults write com.barebones.bbedit "EnableFontLigatures_Fira Code" -bool YES
- RStudio
- Chocolat
- Kate, Konsole, KWrite in Plasma/KDE 5
- Kate, Konsole, KWrite in KDE 4 using Debian Jessie or OS X
- Mancy
- TextAdept (Mac)
Should work (copied from Hasklig README):
- Geany
- gEdit
- Smultron
- Vico
Browser support
- Firefox
- Chromium-based browsers: due to a spec violation (issue 571246) you must explicitly enable contextual alternates in your stylesheet:
font-variant-ligatures: contextual;
Code examples

JavaScript:
Erlang:
Go:

Alternatives
Another monospaced fonts with ligatures:
- Hasklig (free)
- PragmataPro (€59)
- Monoid (free)
Credits
This work is based on OFL-licensed Fira Mono font. Original Fira Mono font was not changed, only extended.
Fira Code was inspired by Hasklig font: Ligatures for Haskell code.
Thanks Georg Seifert for providing a Glyphs 2 license.
Changelog
1.000
Added weights:
- Retina (just slightly heavier than Regular)
- Medium
- Bold
Switched to calt
instead of liga
. You can now “step inside” the ligature in text editors.
Fira Code is now drawn and built in Glyps 2 app (should improve compatibility).
