XVT(1) X Tools XVT(1)NAMExvt (Revised XVT) - a VT102 emulator for the X window system
SYNOPSISxvt [options] [-e command [ args ]]
DESCRIPTION
xvt, version 3.0.0, is a colour vt102 terminal emulator intended as an
xterm(1) replacement for users who do not require features such as Tek‐
tronix 4014 emulation and toolkit-style configurability. As a result,
xvt uses much less swap space -- a significant advantage on a machine
serving many X sessions.
OPTIONS
The xvt options (mostly a subset of xterm´s) are listed below. In
keeping with the less-is-more philosophy, options may be eliminated or
default values chosen at compile-time, so options and defaults listed
may not accurately reflect the version installed on your system. `xvt
-h´ gives a list of major compile-time options on the Options line.
Option descriptions may be prefixed with which compile option each is
dependent upon. e.g. `Compile XIM:´ requires XIM on the Options line.
Note: `xvt -help´ gives a list of all command-line options compiled
into your version.
Note that xvt permits the resource name to be used as a long-option
(--/++ option) so the potential command-line options are far greater
than those listed. For example: `xvt --loginShell --color1 Orange´.
Also note that if you do not explictly specify a font (-fn and -fm) or
a multichar encoding method (-km), xvt will select a font for the
preferable encoding according to your locale. Supported encodings are:
ISO-8859-n (n=1...15), KOI8-R, KOI8-U, EUC-JP, Shift_JIS, EUC-KR,
EUC-CN (aka GB), and Big5.
The following options are available:
-help, --help

the last on the command-line. If there is no -e option then the
default is to run the program specified by the SHELL environment
variable or, failing that, sh(1).

No effect on xvt. Simply passes through an argument to be made
available in the instance´s argument list. Appears in WM_COM‐
MAND in some window managers.
RESOURCES (available also as long-options)
Note: `xvt --help´ gives a list of all resources (long options) com‐
piled into your version. If compiled with internal Xresources support
(i.e. xvt-h lists .Xdefaults) then xvt accepts application defaults
set in XAPPLOADDIR/xvt (compile-time defined: usually
/usr/lib/X11/app-defaults/xvt) and resources set in ~/.Xdefaults, or
~/.Xresources if ~/.Xdefaults does not exist. Note that when reading X
resources, xvt recognizes two class names: XTerm and xvt. The class
name XTerm allows resources common to both xvt and xterm to be easily
configured, while the class name xvt allows resources unique to xvt,
notably colours and key-handling, to be shared between different xvt
configurations. If no resources are specified, suitable defaults will
be used. Command-line arguments can be used to override resource set‐
tings. The following resources are allowed:
geometry: geom
Create the window with the specified X window geometry [default
80x24]; option -geometry.
background: colour
Use the specified colour as the window´s background colour
[default White]; option -bg.
foreground: colour
Use the specified colour as the window´s foreground colour
[default Black]; option -fg.
colorn: colour
Use the specified colour for the colour value n, where 0-7 cor‐
responds to low-intensity (normal) colours and 8-15 corresponds
to high-intensity (bold = bright foreground, blink = bright
background) colours. The canonical names are as follows:
0=black, 1=red, 2=green, 3=yellow, 4=blue, 5=magenta, 6=cyan,
7=white, but the actual colour names used are listed in the COL‐
ORS AND GRAPHICS section.

the image centre (percent). A scale of 0 displays the image
with tiling. A scale of 1 displays the image without any scal‐
ing. A scale of 2 to 9 specifies an integer number of images in
that direction. No image will be magnified beyond 10 times its
original size. The maximum permitted scale is 1000. [default
0x0+50+50]

DEC or unset it will send Delete (code 127) or, if shifted,
Backspace (code 8) - which can be reversed with the appropriate
DEC private mode escape sequence.
deletekey: string
The string to send when the delete key (not the keypad delete
key) is pressed. If unset it will send the sequence tradition‐
ally associated with the Execute key.
cutchars: string
The characters used as delimiters for double-click word selec‐
tion. The built-in default:
BACKSLASH `"´&()*,;<=>?@[]{|}

answerbackString: string
Specify the reply xvt sends to the shell when an ENQ (control-E)
character is passed through. It may contain escape values as
described in the entry on keysym following.
keysym.sym: string
Associate string with keysym sym (0xFF00 - 0xFFFF). It may con‐
tain escape values (\a: bell, \b: backspace, \e, \E: escape, \n:
newline, \r: return, \t: tab, \000: octal number) or control
characters (^?: delete, ^@: null, ^A ...) and may enclosed with
double quotes so that it can start or end with whitespace. The
intervening resource name keysym. cannot be omitted. This
resource is only available when compiled with KEYSYM_RESOURCE.
THE SCROLLBAR
Lines of text that scroll off the top of the xvt window (resource:
saveLines) and can be scrolled back using the scrollbar or by key‐
strokes. The normal xvt scrollbar has arrows and its behaviour is
fairly intuitive. The xterm-scrollbar is without arrows and its behav‐
iour mimics that of xterm
Scroll down with Button1 (xterm-scrollbar) or Shift-Next. Scroll up
with Button3 (xterm-scrollbar) or Shift-Prior. Continuous scroll with
Button2.
MOUSE REPORTING
To temporarily override mouse reporting, for either the scrollbar or
the normal text selection/insertion, hold either the Shift or the Meta
(Alt) key while performing the desired mouse action.
If mouse reporting mode is active, the normal scrollbar actions are
disabled -- on the assumption that we are using a fullscreen applica‐
tion. Instead, pressing Button1 and Button3 sends ESC[6~ (Next) and
ESC[5~ (Prior), respectively. Similarly, clicking on the up and down
arrows sends ESC[A (Up) and ESC[B (Down), respectively.
TEXT SELECTION AND INSERTION
The behaviour of text selection and insertion mechanism is similar to
xterm(1).
Selection:
Left click at the beginning of the region, drag to the end of
the region and release; Right click to extend the marked region;
Left double-click to select a word; Left triple-click to select
the entire line.
Insertion:
Pressing and releasing the Middle mouse button (or Shift-Insert)
in an xvt window causes the current text selection to be
inserted as if it had been typed on the keyboard.
CHANGING FONTS
You can change fonts on-the-fly, which is to say cycle through the
default font and others of various sizes, by using Shift-KP_Add and
Shift-KP_Subtract. Or, alternatively (if enabled) with Alt-> and
Alt-<, where the actual key can be selected using resources small‐
font_key/bigfont_key.
LOGIN STAMPxvt tries to write an entry into the utmp(5) file so that it can be
seen via the who(1) command, and can accept messages. To allow this
feature, xvt must be installed setuid root on some systems.
COLORS AND GRAPHICS
If graphics support was enabled at compile-time, xvt can be queried
with ANSI escape sequences and can address individual pixels instead of
text characters. Note the graphics support is still considered beta
code.
In addition to the default foreground and background colours, xvt can
display up to 16 colours (8 ANSI colours plus high-intensity bold/blink
versions of the same). Here is a list of the colours with their
rgb.txt names.
It is also possible to specify the colour values of foreground, back‐
ground, cursorColor, cursorColor2, colorBD, colorUL as a number 0-15,
as a convenient shorthand to reference the colour name of
color0-color15.
Note that -rv ("reverseVideo: True") simulates reverse video by always
swapping the foreground/background colours. This is in contrast to
xterm(1) where the colours are only swapped if they have not otherwise
been specified. For example,
xvt-fg Black -bg White -rv
would yield White on Black, while on xterm(1) it would yield
Black on White.
ENVIRONMENTxvt sets the environment variables TERM, COLORTERM and COLORFGBG. The
environment variable WINDOWID is set to the X window id number of the
xvt window and it also uses and sets the environment variable DISPLAY
to specify which display terminal to use. xvt uses the environment
variables XVTPATH and PATH to find XPM files.

BUGS
Check the BUGS file for an up-to-date list.
Cursor change support is not yet implemented.
Click-and-drag doesn´t work with X11 mouse report overriding.
Graphics support is fairly crude.
