Fira Code: free monospaced font with programming ligatures

Fira Code

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.

Fira Code is a personal, free-time project with no funding and a huge feature request backlog. If you love it, consider supporting its development via GitHub Sponsors or Patreon. 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 a 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

Some ligatures can be altered or enabled using stylistic sets/character variants:

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

Fira Code is the first programming font to offer dedicated glyphs to render progress bars:

In action:

We hope more programming fonts will adopt this convention and ship their own versions.

Unicode coverage makes Fira Code a 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 the setup I use on macOS:

# install all required build tools
./script/bootstrap_macos.sh

# build the font files
./script/build.sh

# install OTFs to ~/Library/Fonts
cp distr/otf/*.otf ~/Library/Fonts

Alternatively, you can build Fira Code using Docker:

# install dependencies in a container and build the font files
make

# package the font files from dist/ into a zip
make package

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 or you want the font with just Font Awesome and Devicons. The goal is to provide every combination possible in this folder.

For more information see: The FAQ

Variations (Combinations)

The combinations and total number of combinations are provided here for reference if you want to create your own variation of a patched Nerd Font.

Why aren't all variations included ?

Combinations are no longer included by default because of the large inflation in size it caused the Repository and the amount of time it takes to rebuild all of the combinations. This issue would exponentially get worse as the numbers of Fonts and Glyph Sets provided increase.
