## Fira Code: monospaced font with programming ligatures
|
|||
|
|
|
|||
|
|
### 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 evergy 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):
|
|||
|
|
|
|||
|
|
<img src="./blob/master/firacode.png" style="width: 742px; height: 187px;"/>
|
|||
|
|
|
|||
|
|
Compare to Fira Mono (without ligatures):
|
|||
|
|
|
|||
|
|
<img src="./blob/master/firamono.png" style="width: 742px; height: 187px;"/>

### 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
