nix-rice
Bring ricing to Nix!
Why
Nix standard library does not have direct support for colors and their hexadecimal representation, commonly used in package configurations. This library tries to solve this by adding:
- Support to common float operations
- Support to color definitions and transformations (RGBA and HSLA)
- Color serialisation and deserialisation as hexadecimal strings
- Color palette definitions and transformations
How to use it
An example integration to a home-manager configuration is shown inside the home-manager folder. The library is built using only builtin functions and the standard nix library and can be easily used even in single derivations as an overlay.
final: prev:
let
# Fetch library
nix-rice = final.callPackage (
fetchTarball {
url = "https://github.com/bertof/nix-rice/archive/refs/tags/v0.2.1.tar.gz";
sha256 = "1is70gjf59sxccwhz1hl9hdxsd4z8vqsr2rdk3imnmxj9n3jf6j8";
}
) {};
# Parse theme
nord = with nix-rice; palette.tPalette color.hexToRgba (import ../themes/nord.nix);
in
(
rec {
# Build a derivation to hold the ricing
rice = nix-rice // {
# Define the color palette
# You can use any form of map you prefere
# Palette transform functions are applied recursively, including serialisation and deserialisation
colorPalette = with nix-rice; rec {
normal = {
black = nord.n1;
blue = nord.n10;
cyan = nord.n8;
green = nord.n14;
magenta = nord.n15;
red = nord.n11;
white = nord.n5;
yellow = nord.n13;
};
# Use a generated brighter palette and override some colors
bright = palette.brighten 10 normal // {
blue = nord.n9;
black = nord.n2;
red = nord.n12;
white = nord.n6;
};
dark = palette.darken 10 normal // {
black = nord.n0;
blue = nord.n3;
cyan = nord.n7;
white = nord.n4;
};
};
# Font configurations uses the same pattern in home-manager
font = {
normal = {
name = "Cantarell";
package = final.cantarell-fonts;
size = 10;
};
monospace = {
name = "FuraCode Nerd Font Mono";
package = (
final.nerdfonts.override {
fonts = [ "FiraCode" ];
}
);
size = 10;
};
};
# The ricing may contain any kind of information you want to pass to your configurations
opacity = 0.95;
};
}
)While the library interface is mostly set, it might change in the future (new transformations, palette generation, conversion to specific programs configurations). It is therefore suggested to use a pinned version like in the example above.
