## Fira Code: monospaced font with programming ligatures
|
||
|
||

|
||
|
||
#### [Download Fira Code v0.5](https://github.com/tonsky/FiraCode/releases/download/0.5/FiraCode-Regular.otf)
|
||
|
||
### 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.

||

||
### Fira Code (with ligatures):

|
||
|
||
Compare to Fira Mono (without ligatures):

||

|
||
### Editor support
|
||
|
||
Do **not** work:
|
||
|
||
- Atom ([bug](https://github.com/atom/atom/issues/6055))
|
||
- 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))
|
||
- XCode
|
||
- iTerm 2 ([feature request](https://gitlab.com/gnachman/iterm2/issues/3568))
|
||
- OS X Terminal.app
|
||
- Emacs
|
||
- gVim, MacVim
|
||
|
||
Do work:
|
||
|
||
- Visual Studio
|
||
- TextMate 2
|
||
- QtCreator
|
||
- LightTable ([instructions](https://github.com/LightTable/LightTable/issues/1459#issuecomment-57366504))
|
||
- BBEdit ([instructions](https://github.com/i-tu/Hasklig/issues/3#issue-46601683))
|
||
- Chocolat
|
||
|
||
Should work (copied from [Hasklig README](https://github.com/i-tu/Hasklig)):
|
||
|
||
- Geany
|
||
- gEdit
|
||
- Kate
|
||
- Konsole
|
||
- KWrite
|
||
- Smultron
|
||
- Vico
|
||
|
||
_Note:_ I’m not a font designer, and Fira Code is built in sort of [a hacky way](https://github.com/mozilla/Fira/issues/62) from OTF version of Fira Mono. Please forgive me if it doesn’t work for you. Help will be greatly appreciated.

### 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
