bootloadhid.rb

The formula uses my fork of the original repository by ajd4096, that adds a simple build switch.

iosevka.rb

This formula builds Iosevka from source.
Customizations listed in https://github.com/be5invis/Iosevka#build-your-own-style are supported (see the tracking issue for current status).

Run brew info iosevka to see the options.

It is possible to also build Iosevka Slab and the .woff web fonts (with the same variants set).

If you don't want to make any modifications you can also just download and install via brew cask:

$ brew tap homebrew/cask-fonts
$ brew cask install font-iosevka
