### Problem
2016-04-01 15:45:12 +03:00
Programmers use a lot of symbols, often encoded with several characters. For the human brain, sequences like `->` , `<=` or `:=` are single logical tokens, even if they take two or three characters on the screen. Your eye spends a 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.

Fira Code is an extension of the Fira Mono font containing 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.

- Added centered `:` (between digits, e.g. `10:40` )
- Added lowercase-aligned `-` , `*` and `+` (only between lowercase letters, e.g. kebab case `var-name` , pointers `*ptr` etc)
2015-12-18 15:48:45 +03:00
