Image rendering

[adriangalilea]

Are there any plans to render images?

Would like this too, perhaps via magick convert to sixel.

The problem is, detecting sixel support in terminals seems to be completely all over the place. For example, here is my (very custom) sixel detection bash function:

check_sixel_support() {
    if infocmp -1 | grep -q "sixel"; then
        # Sixel support detected directly via terminfo
        return 0
    fi
    if [[ "$TERM_PROGRAM" == "WezTerm" ]]; then
        return 0
    fi
    if [[ "$TERM_PROGRAM" == "Apple_Terminal" ]]; then
        return 1
    fi
    if [[ -n "$WSLENV" ]]; then
        # WSL as of 2024 does not support sixel
        return 1
    fi
    if [[ -n "$ALACRITTY_LOG" || -n "$ALACRITTY_WINDOW_ID" ]]; then
        # Note that Alacritty may be close to releasing sixel support (?)
        # https://github.com/alacritty/alacritty/pull/4763
        return 1
    fi
    if [[ "$TERM" == "xterm-256color" ]]; then
        # sometimes i like cool-retro-term, but alas, no sixels, which...
        # ...it's a retro terminal emulator, so duh
        parent_process=$(ps -p $PPID -o comm=)
        if [[ "$parent_process" == *"cool-retro-term"* ]]; then
            return 1
        fi
    fi
    if [[ "$TERM_PROGRAM" == "WarpTerminal" ]]; then
        return 1
    fi
    if [[ "$TERM_PROGRAM" == "Hyper" ]]; then
        return 1
    fi
    # for anything else, optimistically assume xterm-256color supports sixel
    case "$TERM" in
        xterm-256color | xterm-kitty | mlterm | yaft | wezterm)
            return 0
            ;;
    esac
    # if all else fails, fail
    return 1
}
