## Fira Code: free monospaced font with programming ligatures

<img src="./extras/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

Fira Code is a free monospaced font containing 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.

### Support

<a href="https://github.com/sponsors/tonsky" target="_blank"><img src="./extras/sponsor.png"></a>

Fira Code is a personal, free-time project with no funding and huge [feature request backlog](https://github.com/tonsky/FiraCode/issues). If you love it, consider supporting its development via [GitHub Sponsors](https://github.com/sponsors/tonsky) or [Patreon](https://patreon.com/tonsky). Any help counts!

### What’s in the box?

Left: ligatures as rendered in Fira Code. Right: same character sequences without ligatures.

Fira Code comes with huge variety of arrows. Even better: you can make them as long as you like and combine start/middle/end fragments however you want!

Fira Code is not only about ligatures. Some fine-tuning is done for punctuation and frequent letter pairs.

Fira Code comes with a few different character variants, so that everyone can choose what’s best for them. [How to enable.](https://github.com/tonsky/FiraCode/wiki/How-to-enable-stylistic-sets)

Being programming font, Fira Code has fantastic support for ASCII/box drawing, powerline and other forms of console UIs.

Unicode coverage makes Fira Code great choice for mathematical writing.

### Building Fira Code locally

In case you want to alter FiraCode.glyphs and build OTF/TTF/WOFF files yourself, this is setup I use on macOS:

```bash
# install all required build tools
./script/bootstrap

# build the font files
./script/build

# install OTFs to ~/Library/Fonts
./script/install
```

## Which font?

### TL;DR

* Pick your font family and then select from the `'complete'` directory.
  * If you are on Windows pick a font with the `'Windows Compatible'` suffix.
    * This includes specific tweaks to ensure the font works on Windows, in particular monospace identification and font name length limitations
  * If you are limited to monospaced fonts (because of your terminal, etc) then pick a font with the `'Mono'` suffix.
    * This denotes that the Nerd Font glyphs will be monospaced not necessarily that the entire font will be monospaced

### Ligatures

By the *Nerd Font* policy, the variant with the `'Mono'` suffix is not supposed to have any ligatures.
Use the non-*Mono* variants to have ligatures.

### Explanation

Once you narrow down your font choice of family (`Droid Sans`, `Inconsolata`, etc) and style (`bold`, `italic`, etc) you have 2 main choices:

#### `Option 1: Download already patched font`

 * download an already patched font from the `complete` folder
   * This is most likely the one you want. It includes **all** of the glyphs from all of the glyph sets. Only caution here is that some fonts have glyphs in the _same_ code point so to include everything some had to be moved to alternate code points.

#### `Option 2: Patch your own font`

 * patch your own variations with the various options provided by the font patcher (see each font's readme for full list of combinations available)
   * This is the option you want if the font you use is _not_ already included or you want maximum control of what's included
   * This contains a list of _all permutations_ of the various glyphs. E.g. You want the font with only [Octicons][octicons] or you want the font with just [Font Awesome][font-awesome] and [Devicons][vorillaz-devicons]. The goal is to provide every combination possible in this folder.
