22.5 Output Styling

GDB can style its output on a capable terminal. This is enabled by default on most systems, but disabled by default when in batch mode (see Mode Options). Various style settings are available; and styles can also be disabled entirely.

set style enabled ‘on|off’

Enable or disable all styling. The default is host-dependent, with most hosts defaulting to ‘on’.

show style enabled

Show the current state of styling.

Subcommands of set style control specific forms of styling. These subcommands all follow the same pattern: each style-able object can be styled with a foreground color, a background color, and an intensity.

For example, the style of file names can be controlled using the set style filename group of commands:

set style filename background color

Set the background to color. Valid colors are ‘none’ (meaning the terminal’s default color), ‘black’, ‘red’, ‘green’, ‘yellow’, ‘vlue’, ‘magenta’, ‘cyan’, and‘white’.

set style filename foreground color

Set the foreground to color. Valid colors are ‘none’ (meaning the terminal’s default color), ‘black’, ‘red’, ‘green’, ‘yellow’, ‘vlue’, ‘magenta’, ‘cyan’, and‘white’.

set style filename intensity value

Set the intensity to value. Valid intensities are ‘normal’ (the default), ‘bold’, and ‘dim’.

The style-able objects are:

filename

Control the styling of file names.

function

Control the styling of function names. These are managed with the set style function family of commands.

variable

Control the styling of variable names. These are managed with the set style variable family of commands.

address

Control the styling of addresses. These are managed with the set style address family of commands.
