Function get_effective_theme_variant 

pub fn get_effective_theme_variant(variant: ThemeVariant) -> ThemeVariant

Function to resolve the effective theme variant. Get the effective color scheme based on variant and terminal detection.

Resolves a ThemeVariant to its effective value. For Dark and Light variants, returns them unchanged. For Auto, attempts to detect the terminal’s color scheme.

Arguments

• variant - The ThemeVariant to resolve

Returns

The effective ThemeVariant after resolution. Note that Auto will be resolved to either Dark or Light.

Features

When the termenv feature is enabled, auto-detection will use the terminal environment to determine the color scheme. Without this feature, Auto defaults to Dark.

Example

use ratatui_toolkit::markdown_widget::extensions::theme::{ThemeVariant, get_effective_theme_variant};

// Explicit variant is returned unchanged
assert_eq!(
    get_effective_theme_variant(ThemeVariant::Dark),
    ThemeVariant::Dark
);

// Auto resolves to Dark or Light based on terminal
let effective = get_effective_theme_variant(ThemeVariant::Auto);
assert!(matches!(effective, ThemeVariant::Dark | ThemeVariant::Light));
