## 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.

### 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

- QtCreator
- LightTable ([instructions](https://github.com/LightTable/LightTable/issues/1459#issuecomment-57366504))
- BBEdit ([instructions](https://github.com/i-tu/Hasklig/issues/3#issue-46601683))

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
