## Installation

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

* **Windows**: Download the fonts from the [Releases](https://github.com/be5invis/Iosevka/releases), select the font files and right click, then hit “Install”.  
  
  * On Windows 10 1809 or newer the default font installation is per-user, and it may cause compatibility issues for some applications, mostly written in Java. To cope with this, right click and select “Install for all users” instead. [Ref.](https://youtrack.jetbrains.com/issue/JRE-1166?p=IDEA-200145)
* **[macOS](http://support.apple.com/kb/HT2509)**
  * Standard distribution in Homebrew: 
    ```bash
    brew tap homebrew/cask-fonts
    brew cask install font-iosevka
    ```
  *  Search for other variants using `brew search font-iosevka` and install what you want.
  * Customizable install using Homebrew: see [robertgzr/homebrew-tap](https://github.com/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](https://aur.archlinux.org/packages/ttf-iosevka) using an AUR wrapper or by doing it manually. [All variants](https://aur.archlinux.org/packages/?O=0&SeB=nd&K=ttf-iosevka&SB=n&SO=a&PP=50&do_Search=Go).
  - Void Linux users can install the font with `xbps-install font-iosevka`.
* **FreeBSD**: The font can be installed with `pkg install iosevka`.
* **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.

![Weights sample](images/weights.png)

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](http://be5invis.github.io/Iosevka/specimen).

### 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.

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:

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:

1. Ensure that [`nodejs`](http://nodejs.org) (≥ 12.16.0) and [`ttfautohint`](http://www.freetype.org/ttfautohint/) are present.
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.

### Using a Docker container

A Docker container handling the build environment for you can be found [here](https://github.com/avivace/fonts-iosevka).

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:

1. Create `private-build-plans.toml` file if absent.

2. Add a build plan into `private-build-plans.toml`. The configurable properties are described in the following sections.
   
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 Web font 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.

### Configuring Custom Build

Configuration of build plans are organized under `[buildPlans.<plan name>]` sections in the `private-build-plans.toml`. 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:
  - `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
    - Remove `NWID` and `WWID` OpenType feature.
  - `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.

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

#### Configuring 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](https://developer.mozilla.org/en-US/docs/Web/CSS/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](https://developer.mozilla.org/zh-CN/docs/Web/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:

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