### Problem
2015-05-22 16:30:32 +03:00
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.

### Credits
2015-12-18 15:36:42 +03:00
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
2015-12-18 15:36:42 +03:00
**1.000**:
Added weights:
- Retina (just slightly bolder 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).
