The Lisp function change-options can be used to set various parameters affecting Nuprl's window system. The change-options
function takes an argument list consisting of keywords and associated values. For example, to set the options :host and :font-name to moose and nuprl-20 respectively, put the form
(change-options :host "moose" :font-name "nuprl-20")in your init file . The options, together with their default values (in parentheses) are given below.
:host (NIL). The host where Nuprl windows should appear.:title-bars? (NIL). If T then Nuprl will draw its own title bars.
:host-name-in-title-bars? (T). If T, then the title of each window will include a substring indicating what host the Lisp process is running on.
:no-warp? (T). If T then Nuprl will never warp the mouse. (Mouse warps apparently annoy some users.) In environments where the position of the mouse determines input focus, setting this option to NIL will guarantee that Nuprl retains input focus when windows are closed.
:frame-left (30), :frame-right (98), :frame-top (30), :frame-bottom (98). Each of these should be a number between 0 and 100. They give the boundaries, in terms of percentage of screen width or height, of an imaginary frame within which Nuprl will attempt to place most new windows.
:font-name ("nuprl-13"). The name (a string) of a font to use for the characters in Nuprl windows. Nuprl uses a special 8-bit font. Currently two are available: nuprl-13 and nuprl-20.
:cursor-font-name ("cursor"), :cursor-font-index (22). The name of the font to use for the mouse cursor when it is over a Nuprl window, and an index into that font. The default font should always be available.
:background-color ("white"). The color for the background in Nuprl windows. The value must be a string argument naming a color. Any color in the X-server's default colormap may be used. Nuprl will get a Lisp error (entering the Lisp debugger) if the color does not exist.
:foreground-color ("black"). The color for characters etc. in Nuprl windows.
