The Screen >
Under Windows and X11, you can control the title of Epsilon's main
window. The variables window-caption-file,
window-caption-buffer, and window-caption control what
appears in Epsilon's title bar.
Use the command set-display-look to
make Epsilon's window decoration and screen appearance resemble that
of other editors. It displays a menu of choices. You can select
Epsilon's original look, Brief's look, the look of the DOS Edit
program (the same as the QBasic program), or the look of the Borland
The command toggle-borders removes the
lines separating Epsilon's windows from one another, or restores them.
When there are no window borders, Epsilon provides each window with
its own separate color scheme, in place of the single one selected by
set-color. (You can still use set-color to set the
individual colors in a color scheme, but Epsilon doesn't care which
particular color scheme you select when it displays the contents of
individual windows. It does use your selected color scheme for other
parts of the screen like the echo area or screen border.)
The color schemes Epsilon uses for borderless windows have names like
"window-black", "window-blue" and so forth.
Epsilon assigns them to windows in order. You can remove one from
consideration using the delete-name command, or create a new
one using EEL (see Color Classes).
The rest of this section describes some of the variables set by the
above commands. The set-display-look command in particular
does its work entirely by setting variables. You can make Epsilon
use a custom display look by setting these variables yourself. The
variables also allow some customizations not available through the
The echo-line variable contains the number of
the screen line on which to display the echo area. The
avoid-top-lines and avoid-bottom-lines variables tell
Epsilon how many screen lines at the top and bottom of the screen are
reserved, and may not contain tiled windows. By default,
echo_line contains the number of the last screen line,
avoid-top-lines is zero, and avoid-bottom-lines is one,
to make room for the echo area.
To Epsilon display text in the echo area whenever it's idle, set the
variables show-when-idle and show-when-idle-column.
See their online documentation for details.
To position the echo area at the top of the screen, set
echo-line and avoid-bottom-lines to zero and
avoid-top-lines to one. (If you're using a permanent mouse
menu, set echo-line and avoid-top-lines one higher.)
To completely fill the screen with text, toggle borders off and set
avoid-bottom-lines and avoid-top-lines to zero. Whenever
Epsilon needs to display text in the echo area, it will temporarily
overwrite the last screen line for a moment, and then return to
showing buffer text on every line.
You can customize the position and contents of the mode line Epsilon
displays for ordinary tiled windows by setting variables. These
variables all start with "mode-". See the online help for
mode-format for details. Also see the
You can set several variables to put borders around the screen. If
you want Epsilon to always display a window border at the right edge
of the screen, set the variable border-right nonzero. (The
toggle-scroll-bar command, which turns on permanent scroll
bars for all windows, sets this variable.) Epsilon displays a border
at the left screen edge if border-left has a nonzero value.
Similarly, border-top and border-bottom variables
control borders at the top and bottom edges of the screen, but only
if a tiled window reaches all the way to that edge of the screen. (A
menu bar might be in the way.) All these variables are zero by
default. (Toggling all window borders off with the
toggle-borders command overrides these variables.) If the
border-inside variable is nonzero (as it is by default),
Epsilon displays a border between side-by-side windows. Set it to
zero to eliminate these borders. (The toggle-borders command
sets this variable, among other things.)
