25.5 TUI Configuration Variables

Several configuration variables control the appearance of TUI windows.

set tui border-kind kind

Select the border appearance for the source, assembly and register windows. The possible values are the following:

space: Use a space character to draw the border.
ascii: Use ASCII characters ‘+’, ‘-’ and ‘|’ to draw the border.
acs: Use the Alternate Character Set to draw the border. The border is drawn using character line graphics if the terminal supports them.

set tui border-mode mode

set tui active-border-mode mode

Select the display attributes for the borders of the inactive windows or the active window. The mode can be one of the following:

normal: Use normal attributes to display the border.
standout: Use standout mode.
reverse: Use reverse video mode.
half: Use half bright mode.
half-standout: Use half bright and standout mode.
bold: Use extra bright or bold mode.
bold-standout: Use extra bright or bold and standout mode.

set tui tab-width nchars

Set the width of tab stops to be nchars characters. This setting affects the display of TAB characters in the source and assembly windows.

set tui compact-source [on|off]

Set whether the TUI source window is displayed in “compact” form. The default display uses more space for line numbers and starts the source text at the next tab stop; the compact display uses only as much space as is needed for the line numbers in the current file, and only a single space to separate the line numbers from the source.

Note that the colors of the TUI borders can be controlled using the appropriate set style commands. See Output Styling.
