Struct TerminalCaps 

Source 
pub struct TerminalCaps {
    pub color_level: ColorLevel,
    pub image_protocol: Option<ImageProtocol>,
    pub true_color: bool,
    pub hyperlinks: bool,
    pub kitty_protocol: bool,
    pub sixel: bool,
    pub synchronized_output: bool,
    pub deccara: bool,
    pub cell_size: Option<(u16, u16)>,
    pub terminal_name: Option<String>,
}
Expand description

All detected terminal capabilities. Populated once at bootstrap.

Fields§

§color_level: ColorLevel

Detected color depth. Independent from per-kind booleans below because a Kitty terminal under tmux may still degrade to Ansi256.

§image_protocol: Option<ImageProtocol>

Supported image protocol, if any.

§true_color: bool

Whether the terminal supports 24-bit true color.

§hyperlinks: bool

Whether the terminal supports OSC 8 hyperlinks.

§kitty_protocol: bool

Whether the Kitty keyboard protocol is active.

§sixel: bool

Supports Sixel inline images. Defaults to false.

§synchronized_output: bool

Supports synchronized output (CSI 2026 BSU/ESU). Defaults to true — harmless on unsupported terminals. Disable with OXI_NO_SYNC_OUTPUT=1.

§deccara: bool

Supports Kitty’s DECCARA rectangular background-fill extension. Defaults to false — emitting DECCARA to an unsupported terminal corrupts the display. Enabled for Kitty/Ghostty.

§cell_size: Option<(u16, u16)>

Cell size in pixels (width, height), if detectable.

§terminal_name: Option<String>

Identified terminal family name, if recognized.

Implementations§

Source§

impl TerminalCaps

Source

pub fn detect() -> TerminalCaps

Detect terminal capabilities from environment variables.

Reads NO_COLOR/COLORTERM/TERM for color_level, and TERM/TERM_PROGRAM/KITTY_WINDOW_ID/GHOSTTY_RESOURCES_DIR/ WEZTERM_PANE/ITERM_SESSION_ID/TMUX/OXI_NO_SYNC_OUTPUT for per-kind booleans.

Source

pub fn adapt_theme(&self, theme: &mut Theme)

Downgrade all colors in the theme to match the terminal’s color level. Called once at bootstrap after Theme::dark() etc.

Re-derives crate::theme::ThemeStyles after mutating colors so downstream consumers never observe stale styles.

Source

pub fn supports_images(&self) -> bool

Check if images are supported.
