## Fira Code: monospaced font with programming ligatures
### 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 [Fira Code v1.102](https://github.com/tonsky/FiraCode/releases/download/1.102/FiraCode_1.102.zip) | Read [how to install](https://github.com/tonsky/FiraCode/wiki) | Follow updates 📢 [@FiraCode](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.

### Changelog
#### Work in progress
- Removed `!!!` `???` `;;;` `&&&` `|||` `=~` (#167) `~~~` `%%%`
- New safer `calt` code that doesn’t apply ligatures to long sequences of chars, e.g. `!!!!`, `>>>>`, etc (#49, #110, #176)
- Larger `+` `-` `*` and corresponding ligatures (#86)
#### 1.102
- Support for IntelliJ-based IDEs ([instructions](https://github.com/tonsky/FiraCode/wiki/Intellij-products-instructions))
- Turned on autohinting
#### 1.101
- Added Light weight
- Adjusted rules when vertical centering of `:`, `-`, `*` and `+` occurs
#### 1.100
- Fixed calt table conflicts (`----` would incorrectly render as `` `<--` `&&` `||` `=>>` `=/=`
#### 0.1
`>>=` `=<<` `<<=` `->>` `->` `=>` `<<-` `<-`
`===` `==` `<=>` `>=` `<=` `>>` `<<` `!==` `!=` `<>`
`:=` `++` `#(` `#_`
`::` `...` `..` `!!` `//` `/*` `*/` `/>`
