.SH NAME
xiterm+thai \(em VT102 emulator for the X window system with Thai support
.SH SYNOPSIS
.B xiterm+thai
.RI [ options ]
.RB [ \-e
.I command
.RI [ args ]]
.\"
.\" change the following strings to suit your installation
.\" hk = HOTKEY, bf = BIGFONT, sf = SMALLFONT

.\" end of editing region
.SH DESCRIPTION
.B xiterm+thai
\(em version
.B 1.10
\(em is a color vt102 terminal emulator intended as an
.IR xterm (1)
replacement for users who do not require features such as Tektronix 4014
emulation and toolkit-style configurability.
As a result,
.B xiterm+thai
uses much less swap space \(em a significant advantage on a machine serving
many X sessions.
.SH OPTIONS
The
.B xiterm+thai
options
(mostly a subset of
.IR 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.
.LP
Note that
.B xiterm+thai
permits the resource name to be used as a long-option (\-\-/++ option) so the
potential command-line options are far greater than those listed.

.SH RESOURCES (available also as long-options)
.B xiterm+thai
accepts application defaults set in XAPPLOADDIR/Xiterm (compile-time defined:
usually
.BR /usr/lib/X11/app-defaults/Xiterm )
and resources set in
.B ~/.Xdefaults
or
.BR ~/.Xresources .
Note that when reading X resources,
.B xiterm+thai
recognizes two class names:
.B XTerm
and
.BR Xiterm .
The class name
.B XTerm
allows resources common to both
.B xiterm+thai
and
.I xterm
to be easily configured, while the class name
.B Xiterm
allows resources unique to
.BR xiterm+thai ,
notably colors and key-handling, to be shared between different
.B xiterm+thai
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:
.TP
.BI geometry: " geom"
Create the window with the specified X window geometry [default 80x24]; option
.BR \-geometry .
.TP
.BI background: " color"
Use the specified color as the window's background color

.BR \-bg .
.TP
.BI foreground: " color"
Use the specified color as the window's foreground color
[default Black];
option
.BR \-fg .
.TP
.BI color n : " color"
Use the specified color for the color value
.IR n ,
where 0\-7 corresponds to low-intensity (normal) colors and 8\-15
corresponds to high-intensity (bold = bright foreground, blink = bright
background) colors.
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 color names used are listed in the

Use the specified color for the cursor.
The default is to use the foreground color; option
.BR \-cr .
.TP
.BI cursorColor2: " color"
Use the specified color for the color of the cursor text.
For this to take effect,
.B cursorColor
must also be specified.
The default is to use the background color.

Associate
.I string
with keysym
.I sym
.RB ( 0xFF00
\-
.BR 0xFFFF ).
It may contain escape values (\ea: bell, \eb: backspace, \ee, \eE:
escape, \en: newline, \er: return, \et: tab, \e000: 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
.B keysym.
cannot be omitted.
This resource is only available when compiled with
.BR FAKE_RESOURCES .
.SH "THE SCROLLBAR"
Lines of text that scroll off the top of the
.B xiterm+thai
window (resource:
.BR saveLines )
and can be scrolled back using the scrollbar or by keystrokes.
The normal
.B xiterm+thai
scrollbar has arrows and its behaviour is fairly intuitive.
The
.B xterm-scrollbar
is without arrows and its behaviour mimics that of
.IR xterm .
.LP
Scroll down with
.B Button1
.RB ( "xterm-scrollbar" )
or
.BR Shift-Next .
.br
Scroll up with
.B Button3
.RB ( "xterm-scrollbar" )
or
.BR Shift-Prior .
.br
Continuous scroll with
.BR Button2 .
.SH "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.
.LP
If mouse reporting mode is active, the normal scrollbar actions are disabled
\(em on the assumption that we are using a fullscreen application.
Instead, pressing Button1 and Button3 sends
.BR ESC[6~ " (Next)"
and
.BR ESC[5~ " (Prior),"
respectively.
Similarly, clicking on the up and down arrows sends
.BR ESC[A " (Up) and"
.BR ESC[B " (Down),"
respectively.
.SH "TEXT SELECTION AND INSERTION"
The behaviour of text selection and insertion mechanism is similar to
.IR xterm .
.TP
.BR "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.
.TP
.BR "Insertion" :
Pressing and releasing the Middle mouse button (or
.BR Shift-Insert )
in an
.B xiterm+thai
window causes the current text selection to be inserted as if it had
been typed on the keyboard.
.SH "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
.BR Shift-KP_Add " and "
.BR Shift-KP_Subtract .
Or, alternatively (if enabled) with
.BR \*(hk-\*(bf " and"
.BR \*(hk-\*(sf ,
where the actual key can be selected using resources
.BR smallfont_key / bigfont_key .
.SH "LOGIN STAMP"
.B xiterm+thai
tries to write an entry into the
.B utmp
file (usually
.BR /etc/utmp ),
so that it can be seen via the
.IR who (1)
command, and can accept messages.
To allow this feature,
.B xiterm+thai
must be installed setuid root.
.SH "COLORS AND GRAPHICS"
If graphics support was enabled at compile-time,
.B xiterm+thai
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.
.LP
In addition to the default foreground and background colors,
.B xiterm+thai
can display up to 16 colors (8 ANSI colors plus high-intensity bold/blink
versions of the same).
Here is a list of the colors with their
.B rgb.txt
names.

It is also possible to specify the color values of
.BR foreground ,
.BR background ,
.BR cursorColor ,
.BR cursorColor2 ,
.BR colorBD ,
.B colorUL
as a number 0\-15, as a convenient shorthand to reference the color name of
color0\-color15.
.LP
Note that
.B \-rv
.RB ( "reverseVideo: True" )
simulates reverse video by always swapping the foreground/background colors.
This is in contrast to
.I xterm
where the colors are only swapped if they have not otherwise been specified.
For example,
.TP
.B xiterm+thai \-fg Black \-bg White \-rv
would yield White on Black, while on
.I xterm
it would yield Black on White.
.SH ENVIRONMENT
.B xiterm+thai
sets the environment variables
.BR TERM,
.B COLORTERM
and
.BR COLORFGBG .
The environment variable
.B WINDOWID
is set to the X window id number of the
.B xiterm+thai
window and it also uses and sets the environment variable
.B DISPLAY
to specify which display terminal to use.
.B xiterm+thai
uses the environment variables
.B RXVTPATH
and
.B PATH
to find XPM files.
.SH FILES
.TP 16
.B /etc/utmp
System file for login records.
.TP 16
.B /usr/lib/X11/rgb.txt
Color names.
.SH "SEE ALSO"
.IR xterm (1),

.IR utmp (5)
.SH BUGS
Selecting/pasting very large chunks of text is a problem.
But as is the case for
.IR xterm ,
it is a bug of the pseudo terminal driver of those systems.
.LP
xiterm+thai 1.0 has the utmp support cleaned-up and supports
.B utmpx
(i.e. Solaris 2.x) but there are still some problems.
Please inform the maintainer of the correct solutions to utmp problems
since he doesn't have root access of his own to test utmp.
.LP
Cursor change support is not yet implemented.
.LP
Click-and-drag doesn't work with X11 mouse report overriding.
.LP
Graphics support is fairly crude.
.LP
For some fonts there are problems with pixel-droppings being left behind
when simulated bold (overstrike) precedes a space character.
Fixing
.B xiterm+thai
to handle these cases requires a lot of energy.
So the easiest course by far is to specify a boldFont, specify colorBD or,
if it was compiled without NO_BRIGHTCOLOR, to select a foreground color that
matches the pixel values of color 0\-7 so that overstrike bold won't be used.
.LP
Like
.IR xterm ,
.B xiterm+thai
handles mono-space fonts only, and only TIS-620 fonts are supported.
