Xless(1)Xless(1)WIDGET AND RESOURCE NAMES
In addition to the usual widget resources, Xless has the
following application resources:
standardFont
The default font to be used if any of the speci-
fied fonts are available.
textFont The fonts to use for the text.
labelFont The fonts to use for labels in dialog boxes.
buttonFont
The fonts to use for labels on buttons.
standardCur
The cursors to use in the main button window
with the Quit and Help commands.
dialogCur The cursors to use in the toolbox and dialog box
windows.
helpFile Name of a file to use instead of the system
default helpfile.
editor Name of editor to invoke (if neither VISUAL nor
EDITOR environment variable is set)
editorDoesWindows
Set to TRUE if your editor brings up its own
window (xedit or GNU emacs, for example.)
printCommand
Command string used to print the current file.
The name of the file is simply appended to this
string. (enscript -G is nice, if you've got
it.)
maxWindows
Maximum number of windows which xless will dis-
play at one time. Set this to zero if you don't
want a limit. (This is a good thing to set
if you tend to run xless * in directories with
lots of files.)
quitButton
Set to TRUE if you want a Quit button on every
window which, when clicked, will quit every win-
dow started from this copy of xless. The
default is FALSE.
sizeToFit Set to TRUE if you want text windows to be only
as big as they need to be, up to the maximum

size specified by 'geometry'.
removePath
Set to TRUE if you want the directory portion of
the file path removed. For example, a path like
/usr/src/X11/xless/main.c would be shortened to
main.c. The default is TRUE.
defaultSearchType
Default method used to search the text (invoked
from the Search button). Possible values are
ExactMatch (which is the default), CaseInsensi-
tive and RegularExpression.
monitorFile
Set to TRUE if you want the file to be continu-
ally checked for new input (so that xless
behaves like tail -f). The default is FALSE.
COLOR RESOURCES
If you have a color display and you're running at least
X11R5, you may want to add a line like:
#ifdef COLOR
*customization: -color
#endif
to your personal resources file. This will allow you to
get the color-related resources for not only xless, but
for every program which sets up its own color resources.
Versions of X earlier than X11R5 don't support the cus-
tomization resource. If you're on one of those, you'll
have to include the color resources in your personal
resources file.
