Function Documentation

◆ capture_terminal_response()

string UtilsOSDependable::capture_terminal_response ( )

Captures terminal response to color query.

Returns: string Raw terminal response containing color information

Note: Uses low-level terminal I/O to capture the response

Definition at line 40 of file linux_utils.cpp.

◆ convert_16_bit_to_8_bit()

int UtilsOSDependable::convert_16_bit_to_8_bit ( const string & hex16 )

Converts a 16-bit hex color string to 8-bit RGB components.

Parameters

hex16 16-bit hex color string (format: "RRGGBB" or "#RRGGBB")

Returns: int 8-bit color value (0-255)

Note: Input string can be with or without leading '#'

◆ get_terminal_bg_color_luminance()

float UtilsOSDependable::get_terminal_bg_color_luminance ( )

Gets the luminance of terminal background color.

Gets the luminance of terminal background color on Windows.

Returns: float Luminance value between 0 (dark) and 1 (light)

Note: Uses terminal escape sequences to query background color

Returns: float Luminance value between 0 (dark) and 1 (light)

Note: Uses Windows Console API to determine background color; Defaults to dark if unable to determine color

Definition at line 77 of file linux_utils.cpp.

◆ is_bg_color_dark()

bool UtilsOSDependable::is_bg_color_dark ( )

Determines if terminal background color is dark.

Determines if terminal background color is dark on Windows.

Returns: bool True if background is dark (luminance < 0.5), false otherwise

Note: Uses get_terminal_bg_color_luminance() internally

Returns: bool True if background is dark (luminance < 0.5), false otherwise

Note: Uses get_terminal_bg_color_luminance() internally; Defaults to true (dark) if unable to determine color

Definition at line 89 of file linux_utils.cpp.

◆ parse_terminal_color_response() [1/2]

tuple< int, int, int > UtilsOSDependable::parse_terminal_color_response ( )

Parses terminal color response into RGB components on Windows.

Returns: tuple<int, int, int> RGB components as 8-bit values (0-255)

Note: Uses Windows Console API to get color information; Returns default dark theme colors if unable to determine

◆ parse_terminal_color_response() [2/2]

tuple< int, int, int > UtilsOSDependable::parse_terminal_color_response ( const string & response )

Parses terminal color response into RGB components.

Parameters

response Terminal color response string (format: "rgb:RRRR/GGGG/BBBB")

Returns: tuple<int, int, int> RGB components as 16-bit values (0-65535)

Exceptions

May	throw runtime_error for malformed input
