Raw Blame History

Building Iosevka 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

If you are using Powershell, 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 manually 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:
- normal: The normal monospace font.
- quasi-proportional: The font will become quasi-proportional.
- quasi-proportional-extension-only: The font will become quasi-proportional, but will not shrink narrow letters (like i). Only wide letters (like M) will get expanded.
- term: Make the symbols' width suitable for terminal emulators. Arrows and geometric symbols will become narrower.
- fontconfig-mono: Apply term spacing changes and further apply changes to be compatible with FontConfig's Mono spacing, which recognizes a font as monospace if and only if its every non-combining characters having the same width. The changes 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
      - U+27FB LONG LEFTWARDS ARROW FROM BAR
      - U+27FC LONG RIGHTWARDS ARROW FROM BAR
- fixed: Apply fontconfig-mono changes and further remove ligations.
serifs: Optional, String, configures style of serifs.
- When set to slab, the font will be converted into slab-serif.
- Otherwise the font will be sans-serif.
no-cv-ss: Optional, Boolean, disables cv## and ss## OpenType features.
no-ligation: Optional, Boolean, disables ligations.
export-glyph-names: Optional, Boolean, whether to export glyph names into the fonts. Setting this to true will increase file footprint, however this is necessary for ligature support in Kitty.
webfont-formats: Optional, Array of String. Controls the formats needed to be exported into the webfont CSS. Valid options are 'ttf' and 'woff2', or including both.

Build plan could have 5 optional subsections: ligations, variants, weights, widths and slopes.

Configuring Weights, Widths and Slopes

Subsection weights is used to change the weight grades that the custom family needs. It is a dictionary of either strings formatted in default.<weight> format, meaning reusing a default weight grade, or sub-objects with properties:

shape: Number, 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 width grades that the custom family needs. It is a dictionary of either strings formatted in default.<width> format, meaning reusing a default width grade, or sub-objects with properties:

shape: Number, 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 used to change the slope angles and grades that the custom family needs. It is a dictionary of either strings formatted in default.<slope> format, meaning reusing a default slope grade, or sub-objects with properties:

angle: Number, configures the slope angle in degrees. The valid vales are 0 to 15, inclusive.
shape: String from upright, italic or oblique. Configures the slope used for variant selection.
menu: String from upright, italic or oblique. Configures the slope grade used when naming fonts.
css: String from normal, italic or oblique. Configures the CSS font-style value.

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	520	Height of `x`.
`sb`	emu	(varies, 60 for Regular)	Width of common side-bearings.
`accentWidth`	emu	200	Width of accent marks.
`accentClearance`	emu	72	Vertical clearance of accent marks to the base.
`accentHeight`	emu	176	Height of accent marks.
`accentStackOffset`	emu	220	Offset height of accent mark stack.
`dotSize`	emu	(varies, 125 for regular)	Size of dots in diacritic marks.
`periodSize`	emu	(varies, 140 for regular)	Size of dots in period.
`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`.
`essRatio`	(ratio)	(varies, 1.12 for Regular)	Ratio of the thickness of the neck of `S`/`s`/`?`, to the normal stroke width. `essRatioUpper`, `essRatioLower` and `rssRatioQuestion` will override this value for corresponded glyph categories when set.
`essRatioUpper`	(ratio)	(varies, 1.12 for Regular)	Ratio of the thickness of the neck of `S`, to the normal stroke width.
`essRatioLower`	(ratio)	(varies, 1.12 for Regular)	Ratio of the thickness of the neck of `s`, to the normal stroke width.
`essRatioQuestion`	(ratio)	(varies, 1.12 for Regular)	Ratio of the thickness of the neck of `?`, to the normal stroke width.

The values of each item could be either a number, or a string representing an expression so that it could be different for different instance fonts, or depending on default values. The syntax of valid expressions are:

Expression -> Term (('+' | '-') Term)*
Term       -> Factor (('*' | '/') Factor)*
Factor     -> ('+' | '-')* Primitive
Primitive  -> Literal
            | Call
            | Binding
            | Group
            | List
Literal    -> ['0'..'9']+ ('.' ['0'..'9']+)?
Identifier -> ['A'..'Z', 'a'..'z', '_']+
Call       -> Identifier '(' Expression (',' Expression)* ')'
List       -> Identifier '[' Expression (',' Expression)* ']'
Binding    -> Identifier

Valid identifiers include:

weight: being the weight grade;
width: being the characters' unit width, measured in em-units;
slopeAngle: being the slope angle in degrees;
Default value of all overridable metrics, prefixed with default_, i.e., default cap value will be accessable thorugh default_cap.

Valid functions include:

blend(x, [x1, y1], [x2, y2], ...): Perform a smooth interpolation through data pairs [x1, y1], [x2, y2], ..., against parameter x.

For example, the following configuration:

[buildPlans.iosevka-custom.metric-override]
leading = 1500
sb = 'default_sb * 1.0625 + 15'
dotSize = 'blend(weight, [100, 50], [400, 125], [900, 180])'

will:

Override line height to 1500 em-unit;
Override the sidebearing value by its value multiplied by 1.0625 then added with 15.
Override the dot size by a interpolation against weight: at thin (100) being 50, at regular (400) being 125, and at heavy (900) being 180.

Sample Configuration

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

TTC Building

It is possible to create a customized TTC build by using the following method:

Add a collect plan into private-build-plans.toml, with a from field containing all the TTF groups it needs:
