unsupported theme '{other}'

Error message

unsupported theme '{other}'

What it means

Thrown by UiThemeValue::from_setting when crate::palette::normalize_theme_name (crates/tui/src/palette/themes.rs:906) recognizes the input but returns a canonical name the config-UI theme enum does not offer. Concretely, "terminal" (aliases term/transparent/follow-terminal/inherit), "claude", and "solarized-light" (alias solarized) normalize successfully yet are not in the config_ui match, so they land in the Some(other) arm.

Solutions

1. Pick a UI-selectable theme: system, dark, light, grayscale, catppuccin-mocha, tokyo-night, dracula, gruvbox-dark, matrix, or uwu
2. Use a custom theme selector if you want a user-defined theme instead of a built-in name
3. Upgrade Codewhale if release notes say the theme was added to the config UI

Example fix

# before
theme = "solarized-light"

# after
theme = "gruvbox-dark"

const UI_THEMES: &[&str] = &["system", "dark", "light", "grayscale", "catppuccin-mocha", "tokyo-night", "dracula", "gruvbox-dark", "matrix", "uwu"];

fn theme_is_selectable(value: &str) -> bool {
    crate::palette::normalize_theme_name(value)
        .is_some_and(|name| UI_THEMES.contains(&name))
}

When it happens

Trigger: Setting the theme to "terminal", "claude", "solarized-light", or any of their aliases in the config UI settings path. Custom user-theme selectors are handled earlier via normalize_user_theme_selector and return Custom, so only these palette names trigger it.

Common situations: Copying a theme name that works elsewhere in the palette layer (or in an older build) into the UI setting; a theme renamed or not yet surfaced in the config UI enum.
