Parameters

_attr	Text attribute.
_fg	Foreground color.
_bg	Background color.

Definition at line 95 of file color.h.

#define ANSI_FG_ATTR_COLOR	(	_attr,
		_fg
	)	ANSI_COLOR_PRE _attr ANSI_COLOR_SEP _fg ANSI_COLOR_MODE

Macro to build foreground color with the given text attribute escape sequence string.

Background color is left at current setting.

Parameters

_attr	Text attribute.
_fg	Foreground color.

Definition at line 127 of file color.h.

#define ANSI_FG_BRIGHT_COLOR ( _fg ) ANSI_COLOR_PRE ANSI_SGR_TEXT_BOLD ANSI_COLOR_SEP _fg ANSI_COLOR_MODE

Macro to build bright foreground color escape sequence string.

Background color is left at current setting.

Parameters

_fg	Foreground color.

Definition at line 115 of file color.h.

#define ANSI_FG_COLOR ( _fg ) ANSI_COLOR_PRE ANSI_SGR_TEXT_NORMAL ANSI_COLOR_SEP _fg ANSI_COLOR_MODE

Macro to build normal foreground color escape sequence string.

Background color is left at current setting.

Parameters

_fg	Foreground color.

Definition at line 105 of file color.h.

#define ANSI_NORMAL_COLOR	(	_fg,
		_bg
	)	ANSI_COLOR(ANSI_SGR_TEXT_NORMAL, _fg, _bg)

Macro to build normal color escape sequence string.

Actual colors are dependent on the terminal emulator.

Parameters

_fg	Foreground color.
_bg	Background color.

Definition at line 147 of file color.h.

Function Documentation

int colorprintf	(	const char *	sFgColor,
		const char *	sFmt,
			...
	)

Print output in the specified foreground color.

After printing, the colors are reset to defaults. Subsequent output will be in the default color.

Parameters

sFgColor	ANSI SGR foreground color string.
sFmt	Format string following printf(3) syntax.
...	Variable argument list to print.

Returns: On success, returns the number of characters printed sans any color escape sequents.
On output error, a negative value is returned.

INLINE_IN_H void set_color ( const char * sColor )

Set foreground or background color.

The color is in effect until a new foreground/background color is specified or the colors are reset to default values.

Parameters
