|
||
|
||
### 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](http://sublimetext.userecho.com/topic/433445-opentype-support-ligatures-curly-quotes-contextual-and-alternate-symbols/))
|
||
- Intellij Idea ([vote here](https://youtrack.jetbrains.com/issue/IDEA-127539)), including everything built on top of it (PhpStorm, PyCharm, RubyMine, WebStorm, AppCode, CLion, ReSharper)
|
||
- iTerm 2 ([feature request](https://gitlab.com/gnachman/iterm2/issues/3568))
|
||
- OS X Terminal.app
|
||
- Emacs ([workaround](https://github.com/tonsky/FiraCode/wiki/Setting-up-Emacs))
|
||
- gVim, MacVim
|
||
- Eclipse (Mac and Win, [vote here](https://bugs.eclipse.org/bugs/show_bug.cgi?id=398656))
|
||
- Notepad++
|
||
- Kate, Konsole, KWrite in KDE 4
|
||
- Xamarin Studio/Monodevelop
|
||
|
||
Do work:
|
||
|
||
- Atom (since [1.1](http://blog.atom.io/2015/10/29/atom-1-1-is-out.html), add `atom-text-editor { text-rendering:optimizeLegibility }` to the stylesheet)
|
||
- Xcode (with [this plugin](https://github.com/robertvojta/LigatureXcodePlugin))
|
||
- Visual Studio
|
||
- TextMate 2
|
||
- Coda 2
|
||
- Eclipse (Linux)
|
||
- QtCreator
|
||
- LightTable ([instructions](https://github.com/LightTable/LightTable/issues/1459#issuecomment-57366504))
|
||
- 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](https://github.com/i-tu/Hasklig)):
|
||
|
||
- Geany
|
||
- gEdit
|
||
- Smultron
|
||
- Vico

### Credits
|
||
|
||
This work is based on OFL-licensed [Fira Mono font](https://github.com/mozilla/Fira). Original Fira Mono font was not changed, only extended.
|
||
|
||
Fira Code was inspired by [Hasklig font](https://github.com/i-tu/Hasklig): Ligatures for Haskell code.

### Changelog
|
||
|
||
