Iosevka

Coders’ typeface, built from code.

Chinese and Japanese users → Inziu Iosevka for Chinese and Japanese. (A hinted Composite with M+ and Source Han Sans.)

Installation

Quit your editor/program. Unzip and open the folder.

• Instructions for Windows
• Instructions for macOS
  • Standard distribution in Homebrew: brew tap caskroom/fonts && brew cask install font-iosevka (May be outdated).
  • Customizable install using Homebrew: see robertgzr/homebrew-tap.
• Linux : Copy the TTF files to your fonts directory → Run sudo fc-cache.
  • Arch Linux users can install the font from the AUR here using an AUR wrapper or by doing it manually. All variants.
  • Void Linux users can install the font with xbps-install font-iosevka.

Weights, Variants and OpenType features

The typeface contains seven weights (thin, extra-light, light, regular, medium, bold and heavy) alongside with both italic and oblique versions, with the same metrics as the regular one.

All versions include the same ranges of characters: Latin letters, Greek letters (including Polytonic), some Cyrillic letters, IPA symbols and common punctuations and some symbols. You can check out the full list here.

Iosevka supports accessing all letter variants using OpenType features.

Ligations

Iosevka’s default ligation set is assigned to calt feature, though not all of them are enabled by default.

Iosevka supports Language-Specific Ligations, which is the ligation set enabled only under certain languages. These ligation sets are assigned to custom feature tags, like XHS0.

Building from Source

To build Iosevka you should:

1. Ensure that nodejs (≥ 8.4), ttfautohint, otfcc (≥ 0.9.3) and GNU make (≥ 4.1; BSD make may not work) are runnable in your terminal.
   • Windows users may need to install MinGW and make POSIX utilities accessible (mkdir.exe, cp.exe, cat.exe and rm.exe, in particular) from Command Prompt. Utilities provided by Git for Windows or MSYS2 works fine.
2. Install necessary libs by npm install. If you’ve installed them, upgrade to the latest.
3. make (or gmake).

You will find TTFs in the dist/ directory.

Building the Web Font

The webfonts/ directory is used to build Iosevka for web font uses. To build the web fonts you should:

1. Build Iosevka.
2. Ensure that sfnt2woff and woff2_compress are installed and runnable.
3. Run make web .

The web fonts will be generated into dist/iosevka/web and dist/iosevka-slab/web.

Build Your Own Style

Iosevka comes with several visual styles, however they are inactive using the default build. To build these variants, you should perform custom build:

1. make custom-config [set=<name>] with the parameters listed below to create a configuration. The set=<name> part is optional, it will be set to custom when absent.
2. make custom [set=<name>] to acquire your custom font.
   • make custom-web [set=<name>] is for web fonts.

The first step, make custom-config takes following parameters to set styles of your custom build. All of them are optional, and would default to Iosevka’s default configuration:

• design='<styles>', styles for your custom font set.
• upright='<styles>', styles for uprights only.
• italic='<styles>', styles for italics only.
• oblique='<styles>', styles for obliques only.

You can add arbitary styles for these variables, for example, make custom-config upright='v-l-zshaped v-i-zshaped' && make custom will create a variant with Z-shaped letter l and i for uprights.

The current available styles are:

• Styles for general shape:
  • sans : Sans serif (default).
  • slab : Slab serif. When present, the family of your font would be Iosevka Slab.
• Styles related to ligations and spacing:
  • term : Disable ligations. When this style is present, the font built will not contain ligatures, and its family name will be set to “Iosevka Term”. In case of your OS or editor cannot handle ligatures correctly, you can disable ligations with it.
  • type : Make some symbols, like arrows (→) and mathematical operators full-width.
  • stress-fw : When included, full-width characters varying form U+FF00 to U+FFFF will be boxed to present a clear distinguish between ASCII and Full-width. The family name will be set to “Iosevka StFW”.
• All registered ss## and cv## feature tags, including:
  • ss01~ss10 : Predefined stylistic sets based on other Monospace fonts.
  • cv01~cv45 : Standalone character variants.
• Styles for ligation sets, include:
  • ligset-haskell: Default ligation set would be assigned to Haskell.

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

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.
