//
//
// How to apply color formatting to your log statements:
//
// To set the foreground color:
// Insert the ESCAPE_SEQ into your string, followed by "fg124,12,255;" where r=124, g=12, b=255.
//
// To set the background color:
// Insert the ESCAPE_SEQ into your string, followed by "bg12,24,36;" where r=12, g=24, b=36.
//
// To reset the foreground color (to default value):
// Insert the ESCAPE_SEQ into your string, followed by "fg;"
//
// To reset the background color (to default value):
// Insert the ESCAPE_SEQ into your string, followed by "bg;"
//
// To reset the foreground and background color (to default values) in one operation:
// Insert the ESCAPE_SEQ into your string, followed by ";"
#define XCODE_COLORS_ESCAPE_SEQ "\033["
#define XCODE_COLORS_RESET_FG XCODE_COLORS_ESCAPE_SEQ "fg;" // Clear any foreground color
#define XCODE_COLORS_RESET_BG XCODE_COLORS_ESCAPE_SEQ "bg;" // Clear any background color
#define XCODE_COLORS_RESET XCODE_COLORS_ESCAPE_SEQ ";" // Clear any foreground or background color
// If running in a shell, not all RGB colors will be supported.
// In this case we automatically map to the closest available color.
// In order to provide this mapping, we have a hard-coded set of the standard RGB values available in the shell.
// However, not every shell is the same, and Apple likes to think different even when it comes to shell colors.
//
// Map to standard Terminal.app colors (1), or
// map to standard xterm colors (0).
