The goal of this project is to configure the Iosevka typeface to mimic the look and feel of Berkeley Mono as closely as possible.
It uses Iosevka's extensive build options to select character variants that replicate the distinct aesthetic of Berkeley Mono, creating a free, open-source alternative for fans of that particular style.
The name is a simple mashup: Iosevka + Berkeley = Ioskeley.
This repository uses GitHub Actions to automatically build the font files whenever the configuration is updated.
The easiest way to get the font is to download it directly from the Releases page.

IoskeleyMono-Build.zipfile. - Unzip the file and install the fonts on your system.

Theme used in preview: Kintsugi Dark Flared
This configuration uses specific character variants and custom metrics to closely match the look and feel of Berkeley Mono.
- Custom Metrics: The font's vertical proportions, letter spacing (
sb), and parenthesis size have been manually adjusted. This is the key to capturing Berkeley's characteristically compact and geometric feel. - Distinctive Characters: Key glyphs were chosen to match, including a single-storey
g, flat-arc parentheses(), and a two-circle8. - Clarity and Readability: For the best coding experience, the font uses a dotted zero, open-contour
6and9, and sharp, square punctuation. - High Underscore: The underscore character is raised to ensure it is clearly visible and never blends with the line below.
For a complete list of all choices made to match Berkeley Mono, see the private-build-plans.toml file.
