This is my custom iosevka config.
Grab the latest zip file from releases or build the fonts with nix.
$ nix build github:viperML/iosevka#iosevka-normal.base -L
Nerd fonts are not patched into the font. It is kind of a hack, and all terminals/editors I use support font fallback.
Download symbols separately: https://github.com/ryanoasis/nerd-fonts/tree/master/patched-fonts/NerdFontsSymbolsOnly
It should be easy to fork this repo to use your custom build plan.
This nix flake uses Import From Derivation
to import the package-lock.json. Feel free to change this
behavior to use a fixed hash.
