NAME

    xvt (XVT) - a VT102 emulator for the X window system

SYNOPSIS

xvt [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 Tektronix 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 smaller-is-better 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

No effect on xvt. Simply passes through an argument to be made available in the instance's argument list. Appears in WM_COMMAND in some window managers.

RESOURCES (available also as long-options)

Note: xvt --help gives a list of all resources (long options) compiled 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/local/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 settings. 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.

Use the specified colour for the colour value n, where 0-7 corresponds 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 COLORS AND GRAPHICS section.

deletekey: string

The string to send when the delete key (not the keypad delete key) is pressed. If unset it will send the sequence traditionally associated with the Execute key.

The characters used as delimiters for double-click word selection. The built-in default:
BACKSLASH `"'&()*,;<=>?@[]{|}

preeditType: style

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 contain 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 keystrokes. The normal xvt scrollbar has arrows and its behaviour is fairly intuitive. The xterm-scrollbar is without arrows and its behaviour 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 application. 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 smallfont_key/bigfont_key.

LOGIN STAMP

xvt 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, background, 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.

ENVIRONMENT

xvt 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.

FILES

/etc/utmp

System file for login records.

/usr/lib/X11/rgb.txt

Color names.

See xvtRef.html, or xvtRef.txt for detailed information on recognized escape sequences and menuBar syntax, etc.

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.
