## 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) | 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
|
||
|
||
#### 1.102
|
||
|
||
- Support for IntelliJ-based IDEs ([instructions](https://github.com/tonsky/FiraCode/wiki/Intellij-products-instructions))

- Turned on autohinting
|
||
|
||
|
||
#### 1.101

- Adjusted rules when vertical centering of `:`, `-`, `*` and `+` occurs
|
||
|
||
|
||
#### 1.100
|
||
|
||
- Fixed calt table conflicts (`----` would incorrectly render as `<!--`)
|
||
- 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)
|
||
|
||
