NAME¶
xiterm+thai — VT102 emulator for the X window system with Thai support
SYNOPSIS¶
xiterm+thai [
options] [
-e command [
args]]
DESCRIPTION¶
xiterm+thai — version
1.10 — is a color 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,
xiterm+thai uses much less swap space
— a significant advantage on a machine serving many X sessions.
OPTIONS¶
The
xiterm+thai 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.
Note that
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.
For example: `xiterm+thai --loginShell --color1 Orange'.
- -help,--help

RESOURCES (available also as long-options)¶
xiterm+thai accepts application defaults set in XAPPLOADDIR/Xiterm
(compile-time defined: usually
/usr/lib/X11/app-defaults/Xiterm) and
resources set in
~/.Xdefaults or
~/.Xresources. Note that when
reading X resources,
xiterm+thai recognizes two class names:
XTerm and
Xiterm. The class name
XTerm allows resources
common to both
xiterm+thai and
xterm to be easily configured,
while the class name
Xiterm allows resources unique to
xiterm+thai, notably colors and key-handling, to be shared between
different
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:
- geometry: geom
- Create the window with the specified X window geometry [default 80x24];
option -geometry.
- background: color
- Use the specified color as the window's background color [default White];
option -bg.
- foreground: color
- Use the specified color as the window's foreground color [default Black];
option -fg.
- colorn: color
- Use the specified color for the color value 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 COLORS AND GRAPHICS section.
- colorBD: color
- Use the specified color to display bold characters when the foreground
color is the default.
- colorUL: color
- Use the specified color to display underlined characters when the
foreground color is the default.
- cursorColor: color
- Use the specified color for the cursor. The default is to use the
foreground color; option -cr.
- cursorColor2: color
- Use the specified color for the color of the cursor text. For this to take
effect, cursorColor must also be specified. The default is to use
the background color.
- cursorColorThai: color
- Use the specified color for the cursor while in Thai mode. The default is
to use the foreground color.
- reverseVideo: boolean
- True: simulate reverse video by foreground and background colors;
option -rv, False: regular screen colors [default]; option

- scrollColor: color
- Use the specified color for the scrollbar [default #B2B2B2].
- backgroundPixmap: file[;geom]
- Use the specified XPM file (note the `.xpm' extension is optional) for the
background and also optionally specify its scaling with a geometry string
WxH+X+Y, in which W/H specify the horizontal/vertical
scale (percent) and X/Y locate the image centre (percent). A
scale of 0 displays the image with tiling. A scale of 1 displays the image
without any scaling. A scale of 2 to 9 specifies the number of images in
that direction. No image will be magnified beyond 10 times its original
size. The maximum permitted scale is 1000. [default 100x100+50+50]

font2: 6x13
font3: 8x13
font4: 9x15
- boldFont: fontname
- Specify the name of the bold font to use if colorBD has not been
specified and it is not possible to map the default foreground color to
color 8-15 [default NONE]. This font must be the same height and width as
the normal font; option -fb.
- kfont: fontname
- Select the main Kanji text font used [default k14]; option
-fk.
- kfontn: fontname

manager window, it also sets the window's title unless it is explicitly
set; option -n.
- mapAlert: boolean
- True: de-iconify (map) on receipt of a bell character.
False: no de-iconify (map) on receipt of a bell character
[default].
- visualBell: boolean
- True: use visual bell on receipt of a bell character; option

[default].
- cutchars: string
- The characters used as delimiters for double-click word selection. The
built-in default:
TAB SPACE BACKSLASH `"'&()*,;<=>?@[]{|}
- 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 FAKE_RESOURCES.
Lines of text that scroll off the top of the
xiterm+thai window
(resource:
saveLines) and can be scrolled back using the scrollbar or
by keystrokes. The normal
xiterm+thai 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.
- 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 xiterm+thai 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¶
xiterm+thai tries to write an entry into the
utmp file (usually
/etc/utmp), so that it can be seen via the
who(1) command, and
can accept messages. To allow this feature,
xiterm+thai must be
installed setuid root.
COLORS AND GRAPHICS¶
If graphics support was enabled at compile-time,
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.
In addition to the default foreground and background colors,
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
rgb.txt
names.
color0 (black)= Black
color1 (red)= Red3
color2 (green)= Green3
color3 (yellow)= Yellow3
color4 (blue)= Blue3
color5 (magenta)= Magenta3
color6 (cyan)= Cyan3
color7 (white)= AntiqueWhite
color8 (bright black)= Grey25
color9 (bright red)= Red
color10 (bright green)= Green
color11 (bright yellow)= Yellow
color12 (bright blue)= Blue
color13 (bright magenta)= Magenta
color14 (bright cyan)= Cyan
color15 (bright white)= White
foreground = Black
background = White
It is also possible to specify the color values of
foreground,
background,
cursorColor,
cursorColor2,
colorBD,
colorUL as a number 0-15, as a convenient shorthand to reference the
color name of color0-color15.
Note that
-rv (
reverseVideo: True) simulates reverse video by
always swapping the foreground/background colors. This is in contrast to
xterm where the colors are only swapped if they have not otherwise been
specified. For example,
- xiterm+thai -fg Black -bg White -rv
- would yield White on Black, while on xterm it would yield Black on
White.
ENVIRONMENT¶
xiterm+thai sets the environment variables
TERM, COLORTERM
and
COLORFGBG. The environment variable
WINDOWID is set to the X
window id number of the
xiterm+thai window and it also uses and sets
the environment variable
DISPLAY to specify which display terminal to
use.
xiterm+thai uses the environment variables
RXVTPATH and
PATH to find XPM files.
FILES¶
- /etc/utmp
- System file for login records.
- /usr/lib/X11/rgb.txt
- Color names.

BUGS¶
Selecting/pasting very large chunks of text is a problem. But as is the case for
xterm, it is a bug of the pseudo terminal driver of those systems.
xiterm+thai 1.0 has the utmp support cleaned-up and supports
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.
Cursor change support is not yet implemented.
Click-and-drag doesn't work with X11 mouse report overriding.
Graphics support is fairly crude.
For some fonts there are problems with pixel-droppings being left behind when
simulated bold (overstrike) precedes a space character. Fixing
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.
Like
xterm,
xiterm+thai handles mono-space fonts only, and only
TIS-620 fonts are supported.
