iced Adapter

The iced feature maps Opaline themes onto iced's Palette and Custom theme types, so a single TOML theme drives both your terminal UI and your desktop GUI.

opaline = { version = "0.4", features = ["iced"] }

Color Conversion

OpalineColor converts to iced::Color:

use opaline::OpalineColor;
use iced::Color;

let color = OpalineColor::new(225, 53, 255);
let iced_color: Color = color.into();
// → Color::from_rgb8(225, 53, 255)

Palette Generation

Convert a full Opaline theme to an iced Palette:

use opaline::adapters::iced::to_iced_palette;

let theme = opaline::Theme::default();
let palette = to_iced_palette(&theme);

Token → Palette Mapping

Opaline Token	Palette Field
bg.base	background
text.primary	text
accent.primary	primary
success	success
warning	warning
error	danger

iced derives the rest of its widget colors (weak, strong, hover variants) from these six slots.

Custom Theme

to_iced_custom wraps the palette in an iced Custom theme named after the Opaline theme. Drop it into iced::Theme::Custom:

use std::sync::Arc;
use iced::Theme;
use opaline::adapters::iced::to_iced_custom;

let theme = opaline::Theme::default();
let custom = to_iced_custom(&theme);
let iced_theme = Theme::Custom(Arc::new(custom));

Return iced_theme from your application's theme method and every widget picks it up.

If you need the derived tints directly, to_iced_extended returns the Extended palette that iced generates from the base palette.

Runtime Theme Switching

use std::sync::Arc;
use iced::Theme;
use opaline::adapters::iced::to_iced_custom;

fn switch_theme(theme_name: &str) -> Theme {
    let theme = opaline::load_by_name(theme_name).expect("valid theme");
    Theme::Custom(Arc::new(to_iced_custom(&theme)))
}

All 39 builtin themes work with iced. iced decides between its dark and light widget styling from the lightness of background, which agrees with each builtin theme's declared variant.
