## Fira Code: monospaced font with programming ligatures

<img src="https://dl.dropboxusercontent.com/u/561580/imgs/fira_code_logo.svg">

### Problem

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.

### Solution

#### [Download v1.204](https://github.com/tonsky/FiraCode/releases/download/1.204/FiraCode_1.204.zip) · [How to install](https://github.com/tonsky/FiraCode/wiki) · [News & updates](https://twitter.com/FiraCode)

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.

Redrawn:

`{-` `-}` `~=` `=~` `=<<` `>>=` `<$>` `<=>` `.=`

Removed: `?:`

Total ligatures count: 115

`**` `***` `+++` `--` `---` `?:`  
`/=` `/==` `.=` `^=` `=~` `?=` `||=` `|=`

Fixed width of `&&` and `||`

#### 0.1

`>>=` `=<<` `<<=` `->>` `->` `=>` `<<-` `<-`  
`===` `==` `<=>` `>=` `<=` `>>` `<<` `!==` `!=` `<>`  
`:=` `++` `#(` `#_`  
`::` `...` `..` `!!` `//` `/*` `*/` `/>`
