OpenBSD: Run pkg_info -Q iosevka to see which Iosevka packages are available. Use pkg_add to install the chosen package(s).

Features

In the official package, Iosevka provides 6 monospace subfamilies and 3 quasi-proportional subfamilies. In all the monospace subfamilies, 9 weights (Thin to Heavy), 2 widths (Normal and Extended), and 3 slopes (Upright, Italic and Oblique) are included. In the quasi-proportional subfamilies, the quantity of widths is reduced to 1.

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.

Stylistic Sets

Monospace Iosevka contains various stylistic sets to change the shape of certain characters. Enabling corresponded OpenType feature to enable.

`ss01`	Andale Mono Style

`ss02`	Anonymous Pro Style

`ss03`	Consolas Style

`ss04`	Menlo Style

`ss05`	Fira Mono Style

`ss06`	Liberation Mono Style

`ss07`	Monaco Style

`ss08`	Pragmata Pro Style

`ss09`	Source Code Pro Style

`ss10`	Envy Code R Style

`ss11`	X Window Style

`ss12`	Ubuntu Mono Style

`ss13`	Lucida Style

`ss14`	JetBrains Mono Style

`ss15`	IBM Plex Mono Style

`ss16`	PT Mono Style

`ss17`	Recursive Mono Style

`ss20`	Curly Style

Character Variants

Alongside stylistic sets, Monospace Iosevka can also be configured to cherry-pick variants for each character using OpenType. The variants are shown below. To enable, assign the feature tag to the variant index. For example, setting cv11 to 2 will enable single-storey a.

Caution : Certain software may limit the quantity of OpenType features and drop some of them if the feature list is too long. Please validate your feature configuration to ensure that it worked in your software.

Ligations

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

`calt off`	Ligation Off

`calt`	Default setting in text editors

Iosevka supports Language-Specific Ligations, which is the ligation set enabled only under certain languages. These ligation sets are assigned to custom feature tags. To use them, you need to turn off calt and enable the corresponded feature. The feature list is:

`dlig`	Discretionary ligatures

`CLIK`; `JSPT`; `PHPX`	C-Like, JavaScript, PHP

`MLXX`; `FSHP`	ML, F#

`FSTA`	F*

`HSKL`; `IDRS`; `ELMX`; `PURS`	Haskell, Idris, Elm, PureScript

`SWFT`	Swift

`COQX`	Coq

`MTLB`	Matlab

`VRLG`	Verilog

`WFLM`	Wolfram Language (Mathematica)

Please note that, due to the complex interactions when forming ligations, cherry-picking ligation groups will require a custom Iosevka build. The instructions could be seen below.

Building from Source

To build Iosevka you should:

Ensure that nodejs (≥ 12.16.0) and ttfautohint are present, and accessible from PATH.
Run npm install. This command will install all the NPM dependencies, and will also validate whether external dependencies are present.
npm run build -- contents::iosevka.

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

Using a Docker container

A Docker container handling the build environment for you can be found here.

To pull it from Docker Hub and start a standard build of the latest released version, run

docker run -it -v $(pwd):/build avivace/iosevka-build

Fonts files will be placed in the dist folder.

You can provide private-build.plans.toml for a customized build and/or specify the desired release appending -e FONT_VERSION=X.X.X. to the Docker command.

Customized Build

To create a custom build, you need:

Create private-build-plans.toml file if absent.
Add a build plan into private-build-plans.toml. The configurable properties are described in the following sections.
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 Web font CSS;
2. ttf::<plan> : TTF;
3. ttf-unhinted::<plan> : Unhinted TTF only;
4. webfont::<plan> : Web fonts only (CSS + WOFF2);
5. woff2::<plan> : WOFF2 only.

Configuring Custom Build

Configuration of build plans are organized under [buildPlans.<plan name>] sections in the private-build-plans.toml. You can use the Customizer to create the build plan, and/or manulally edit them, following the instructions below.

Inside the plan, top-level properties include:

family: String, defines the family name of your custom variant.
spacing: Optional, String, denotes the spacing of the custom variant. Valid values include:

  - Completely remove wide glyphs. All non-combining glyphs will be exactly the same width.
    - As a consequence, the following characters will be removed:
      - U+27F5 LONG LEFTWARDS ARROW
      - U+27F6 LONG RIGHTWARDS ARROW
  - Remove NWID and WWID OpenType feature.
- fixed: Apply fontconfig-mono changes and further remove ligations.

Configuring Weights, Widths and Slopes

Subsection weights is used to change the weight grades that the custom family needs. It is a dictionary of sub-objects with properties:

shape: Integer, configures the weight grade of the glyphs' shapes.
menu: Integer, configures the weight grade used when naming fonts.
css: Integer, configures the weight grade used in web font CSS.

Subsection widths is used to change the weight grades that the custom family needs. It is a dictionary of sub-objects with properties:

shape: Integer, configures the width of the glyphs' shapes, measured in 1/1000 em.
menu: Integer, configures the width grade used when naming fonts. The valid values are 1 to 9, inclusive.
css: String, configures the font-stretch value used in web font CSS.

Subsection slopes is a simple string-to-string dictionary maps slopes (upright, italic or oblique) to CSS font-style values, represented in string.

Compatibility Ligatures

Certain software, notably Emacs, relies on pre-encoded ligatures instead of OpenType to provide ligations. Iosevka could be configured with additional subsection compatibility-ligatures, being an array of records with following fields:

unicode: The PUA code point being assigned to.
featureTag: The feature tag to compute ligations.
sequence: The source character sequence.

A sample of compatibility ligature config is:

[[buildPlans.iosevka-custom.compatibility-ligatures]]
unicode = 57600 # 0xE100
featureTag = 'calt'
sequence = '<*>'

Metric Override

Subsection metric-override provides ability to override certain metric values, if you reallly want to. Adding this section is strongly discouraged as it may introduce broken geometry or broken shapes.

Property	Unit	Default Value	Meaning
`cap`	emu	735	Height of `H`.
`xheight`	emu	530	Height of `x`.
`sb`	emu	(varies, 60 for Regular)	Width of common side-bearings.
`leading`	emu	1250	Built-in line height.
`symbolMid`	emu	340	Height of the center of hyphen (`-`).
`parenSize`	emu	966	Height of Parentheses.
`winMetricAscenderPad`	emu	0	Additional pad for Win metrics’ ascender to avoid clipping in legacy Windows applications.
`winMetricDescenderPad`	emu	0	Additional pad for Win metrics’ descender to avoid clipping in legacy Windows applications.
`powerlineScaleX`, `powerlineScaleY`	(ratio)	1	X and Y scale of Powerline glyphs.
`powerlineShiftX`, `powerlineShiftY`	emu	0	X and Y shift of Powerline glyphs.
`onumZeroHeightRatio`	(ratio)	1.145	Ratio of height of `0` under `onum` feature, to the height of `x`.

Sub-subsection metric-override.multiplies and metric-override.adds could be used to override the value by multiplying a scale to the default value, then add a shift to it further. The following configuration

[buildPlans.iosevka-custom.metric-override]
leading = 1500

[buildPlans.iosevka-custom.metric-override.multiplies]
sb = 1.0625

[buildPlans.iosevka-custom.metric-override.adds]
sb = 15

will:

Override line height to 1500 em-unit;
Override the sidebearing value by its value multiplied by 1.0625 then added with 15.

Sample Configuration

A sample configuration could be found at private-build-plans.sample.toml.
