Iosevka

Iosevka

Coders’ typeface, built from code.

Installation

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

• Instructions for Windows
• Instructions for macOS
  • Standard distribution in Homebrew: brew tap homebrew/cask-fonts && brew cask install font-iosevka (May be outdated).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.
• FreeBSD: The font can be installed with pkg install iosevka.

Weights, Variants and OpenType features

The typeface contains 9 weights (Thin to 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).
2. Install necessary libs by npm install. If you’ve installed them, upgrade to the latest.
3. npm run build -- contents:iosevka.

You will find TTFs, as well as WOFF(2) web fonts and one Webfont CSS in the dist/ directory.

Build Your Own Style

Since version 2.0, Iosevka would no longer support building via makefile. To initialize a custom build, you need:

1. Create private-build-plans.toml file.

2. Add a build plan into private-build-plans.toml, following this format:

   [buildPlans.iosevka-custom]            # <iosevka-custom> is your plan name
   family = "Iosevka Custom"              # Font menu family name
   design = ["common styles"]             # Common styles
   upright = ["upright-only", "styles"]   # Upright-only styles
   italic = ["italic-only", "styles"]     # Italic-only styles
   oblique = ["oblique-only", "styles"]   # Oblique-only styles
   
   # Override default building weights
   # When buildPlans.<plan name>.weights is absent
   # All weights would built and mapped to default shape/CSS
   [buildPlans.iosevka-custom.weights.regular]
   shape = 400                            # Weight for glyph shapes
   menu  = 400                            # Weight for menu name
   css   = 400                            # Weight for WebFont CSS
   
   [buildPlans.iosevka-custom.weights.bold]
   shape = 700
   menu  = 700
   css   = 700
   
   # Override default building slant sets
   # Format: <upright|italic|oblique> = <"normal"|"italic"|"oblique">
   # When this section is absent, all slants would be built.
   [buildPlans.iosevka-custom.slants]
   upright = "normal"
   italic = "italic"
   oblique = "oblique"

3. Run npm run build -- contents:<your plan name> and the built fonts would be available in dist/. Aside from contents:<plan>, other options are:

   1. contents:<plan> : TTF (Hinted and Unhinted), WOFF(2) and Webfont CSS;
   2. ttf:<plan> : TTF;
   3. ttf-unhinted:<plan> : Unhinted TTF only;
   4. woff:<plan> : TTF and WOFF only;
   5. woff2:<plan> : TTF and WOFF2 only;

The current available styles for design/upright/italic/oblique options are:

• Styles for general shape:
  • sans : Sans serif (default).
  • slab : Slab serif.
• Styles related to ligations and spacing:
  • term : Disable ligations and exact monospace.
    • The font built will not contain ligatures.
    • All glyphs wider than one letter would be deleted.
    • In case of your OS or editor cannot handle ligatures correctly, you can disable ligations with it.
  • termlig : Similar to term, the font is exact monospace to make fontconfig happy, while ligations are still present.
  • nolig : Disable ligation only.
  • 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.
• All registered ss## and cv## feature tags, including:
  • ss01~ss10 : Predefined stylistic sets based on other Monospace fonts.

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.
