NAME
aterm (Afterstep XVT) - a VT102 emulator for the X window system
SYNOPSIS
aterm [options] [-e command [ args ]]
DESCRIPTION
aterm, version 1.0.0, is a colour vt102 terminal emulator,
based on rxvt 2.4.8 with Alfredo Kojima's additions of fast transparency,
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, aterm uses much less swap space -- a significant
advantage on a machine serving many X sessions.
It was created with AfterStep Window Manger users in mind, but is not tied
to any libraries, and can be used anywhere.
OPTIONS
The aterm 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 aterm 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: `aterm --loginShell --color1 Orange'.
-help, --help
Print out a message describing available options.
-version, --version
Print out a version with/without list of available options.
-displaydisplayname
Attempt to open a window on the named X display (-d still
respected). In the absence of this option, the display specified
by the DISPLAY environment variable is used.
-geometrygeom
Window geometry (-g still respected);
resource geometry.
Specify image file for the background and also optionally specify
geometry of the image to be cut out of original image, to be used
as background, with a geometry string. Note you may need to add
quotes to avoid special shell interpretation of the `;' in the
command-line;
resource backgroundPixmap.
-mst:name
Specify the name of the Afterstep MyStyle to be used as the base of
aterm's look. ForeColor, BackColor, Font, BackPixmap (all texture
options) will be used from MyStyle definition, unless some other
command line option is specifyed for the same setting.
For example -fn will override MyStyle Font. This is available only
if used with AfterStep 1.9.28 or later and if compiled with AfterStep
libraries support ( --enable-afterstep-lib).
resource MyStyle.
-tr|+tr
Turn on/off pseudo transparency mode. In this mode aterm
will use part of root background as it's own background, emulating
see-through effect;
resource transparent.
-trsb|+trsb
Turn on/off pseudo transparent scrollbar. Works the same as -tr;
resource transpscrollbar.
-tintcolor
Turn on pseudo transparency background tinting. Tinting can be done
fast and slow way. In fast way it will be done by combining of background
color with tinting color using logical function. This function defaults
to AND, and it can be changed using -tinttype option - see below.
In general solid colors like Blue, Red, Green, Cyan, Magenta, Yellow
are good, but you should experiment with it for each background you have.
True tinting is more memory and CPU hungry - tinted copy of background
image will be created every time you move/resize window. It alows for more
smooth tinting thou.
You need to build it with --enable-transparency=yes or
--enable-background-imageyes option, to be able to use this feature.
resource tinting.
-shamount
This option allows for darkening/lightening of the background image
amount is the %value of the desired brightness, where 100 is the
original.
if amount is less then 100 - image will be darkened.
if amount is less then 0 or more then 100 - image will be lightened.
Lightening can cause some strange looking effects if applied on bright image.
This option causes aterm to create shaded/lightened copy of the background -
it's more memory cosuming as the result. It does not make much difference,
though, if applied on non transparent background image.
resource shading.
-fadeamount
This option allows for darkening/lightening of colors when aterm is
loosing focus.
amount is the %value of the desired brightness, where 100 is the
original.
if amount is less then 100 - colors will be darkened.
if amount is less then 0 or more then 100 - colors will be lightened.
Lightening can cause some strange looking effects if applied on bright colors.
This option causes aterm to use more colors, as the result it is disabled by
default. Use --enable-fading ./configure option to enable it.
resource fading.
-bgtypetype
Specify type of the transformation to be performed on background
image. Possible types are :
tile - plain vanilla tiling of the image.
scale - original image will be scaled to the aterm's size, every
time you resize window.
scalev - original image will be scaled to the aterm's height only,
every time you resize window.
scaleh - original image will be scaled to the aterm's width only,
every time you resize window.
center - original image will be centered in aterm's window.
notile - background color will be padded to image's right/bottom
to make it the same size as window is.
notileh - background color will be padded to image's right
to make it the same width as window is.
notilev - background color will be padded to image's bottom
to make it the same height as window is. cut - aterm background will be cut out of the source image,
as if this source image was tiled across the root window. The
portion of the image that lies underneath of window will be used.
If AfterStep Pager, asetroot or Esetroot where used to set the root
image, then this option can be used in conjunction with -tr option.
In this case it will do mentioned transformations to the root pixmap.
and use it as aterm's background.
resource backgroundType.
-txttypetype
Allows you to specify logical function to be used when displaying
text. That will cause aterm to logically combine text with
background pixels. That only works with transparent background
and background image. Possible values are :
and, andReverse, andInverted, xor, or, nor,
invert, equiv, invert, orReverse, orInverted,
nand;
resource textType.
-tinttypetype
Allows you to specify logical function to be used when tinting
transparent background. That will cause aterm to logically combine
text with background pixels. NOTE: If shading option is used,
or background image is specifyed - true type will always be used.
That works with bpth transparent background and background image.
Possible values are :
Slow tinting:
true - will do "true" tinting - that means that background pixel's
RGB components will be decreased proportionaly to the RGB components
of specified tinting color;
resource tintingType.
-crcolour

-tntermname
This option specifies the name of the terminal type to be set in the
TERM environment variable. This terminal type must exist in the
termcap(5) database and should have li# and co# entries;
resource termName.
-ecommand [arguments]
Run the command with its command-line arguments in the aterm
window; also sets the window title and icon name to be the basename
of the program being executed if neither -title (-T) nor
-n are given on the command line. If this option is used, it
must be 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).
-titletext
Window title -T still respected); the default title is the
basename of the program specified after the \f3\-e\fP option, if
any, otherwise the application name;
resource title.
-ntext
Icon name; the default name is the basename of the program specified
after the \f3\-e\fP option, if any, otherwise the application name;
resource iconName.
-C
Capture system console messages.
RESOURCES (available also as long-options)
aterm accepts application defaults from the X server resource database.
xrdb is used to update this database.
Note that when reading X resources,
aterm recognizes two class names: XTerm and Aterm. The class name
XTerm allows resources common to both aterm and xterm to be easily
configured, while the class name Aterm allows resources unique to aterm,
notably colours and key-handling, to be shared between different aterm
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.
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
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.
colorBD:colour
Use the specified colour to display bold characters when the
foreground colour is the default.
colorUL:colour
Use the specified colour to display underlined characters when the
foreground colour is the default.
cursorColor:colour
Use the specified colour for the cursor. The default is to use the
foreground colour;
option -cr.
cursorColor2:colour
Use the specified colour for the colour of the cursor text. For this
to take effect, cursorColor must also be specified. The default
is to use the background colour.
reverseVideo:boolean
True: simulate reverse video by foreground and background colours;
option -rv,
False: regular screen colours [default];
option +rv.
See note in COLORS AND GRAPHICS section.
scrollColor:colour
Use the specified colour for the scrollbar [default #B2B2B2].
troughColor:colour
Use the specified colour for the scrollbar's trough area [default
#969696].
backgroundPixmap:file[;geom]
Use the specified image file, and cut the area defined by geometry
string out of it.
MyStyle:name
Specify the name of the Afterstep MyStyle to be used as the base of
aterm's look. ForeColor, BackColor, Font, BackPixmap (all texture
options) will be used from MyStyle definition, unless some other
command line option is specifyed for the same setting.
For example resource font will override MyStyle Font.
This is available only if used with AfterStep 1.9.28 or later and
if compiled with AfterStep libraries support ( --enable-afterstep-lib).
transparent
Turn on/off pseudo transparency mode. In this mode aterm
will use part of root background as it's own background, emulating
see-through effect;
tinting:color
Turn on pseudo transparency background tinting. Tinting can be done
fast and slow way. In fast way it will be done by combining of background
color with tinting color using logical function. This function defaults
to AND, and it can be changed using -tinttype option - see below.
In general solid colors like Blue, Red, Green, Cyan, Magenta, Yellow
are good, but you should experiment with it for each background you have.
True tinting is more memory and CPU hungry - tinted copy of background
image will be created every time you move/resize window. It alows for more
smooth tinting thou.
You need to build it with --enable-transparency=yes or
--enable-background-image=yes option, to be able to use this feature.
-shading:amount
This option allows for darkening/lightening of the background image
amount is the %value of the desired brightness, where 100 is the
original.
if amount is less then 100 - image will be darkened.
if amount is less then 0 or more then 100 - image will be lightened.
Lightening can cause some strange looking effects if applied on bright image.
This option causes aterm to create shaded/lightened copy of the background -
it's more memory cosuming as the result. It does not make much difference,
though, if applied on non transparent background image.
backgroundType:type
Specify type of the transformation to be performed on background
image. Possible types are :
tile - plain vanilla tiling of the image.
scale - original image will be scaled to the aterm's size, every
time you resize window.
scalev - original image will be scaled to the aterm's height only,

every time you resize window.
center - original image will be centered in aterm's window.
notile - background color will be padded to image's right/bottom
to make it the same size as window is.
notileh - background color will be padded to image's right
to make it the same width as window is.
notilev - background color will be padded to image's bottom
to make it the same height as window is. cut - aterm background will be cut out of the source image,
as if this source image was tiled across the root window. The
portion of the image that lies underneath of window will be used.
If AfterStep Pager, asetroot or Esetroot where used to set the root
image, then this option can be used in conjunction with -tr option.
In this case it will do mentioned transformations to the root pixmap.
and use it as aterm's background.
textType:type
Allows you to specify logical function to be used when displaying
text. That will cause aterm to logically combine text with
background pixels. That only works with transparent background
and background image. Possible values are :
and, andReverse, andInverted, xor, or, nor,
invert, equiv, invert, orReverse, orInverted,
nand.
tintingTypetype
Allows you to specify logical function to be used when tinting
transparent background. That will cause aterm to logically combine
text with background pixels. NOTE: If shading option is used,
or background image is specifyed - true type will always be used.
That works with bpth transparent background and background image.
Possible values are :
Slow tinting:
true - will do "true" tinting - that means that background pixel's
RGB components will be decreased proportionaly to the RGB components
of specified tinting color.

True: inhibit writing record into the system log file utmp;
option -ut.
False: write record into the system log file utmp [default];
option +ut.
print-pipe:string
Specify a command pipe for vt100 printer [default lpr(1)]. Use
Print to initiate a screen dump to the printer and Ctrl-Print
or Shift-Print to include the scrollback as well.

option -sl.
termName:termname
Specifies the terminal type name to be set in the TERM
environment variable;

modifier:string
Set the Meta key to be enabled by modifier Mod1, Mod2, Mod3,
Mod4 or Mod5.
backspacekey:string
The string to send when the backspace key is pressed. If set to
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 traditionally associated
with the Execute key.
cutchars:string
The characters used as delimiters for double-click word selection.
The built-in default:
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 KEYSYM_RESOURCE.
THE SCROLLBAR
Lines of text that scroll off the top of the aterm window (resource:
saveLines) and can be scrolled back using the scrollbar or by keystrokes.
The normal aterm scrollbar has arrows and its behaviour is fairly
intuitive. The xterm-scrollbar is without arrows and its behaviour
mimics that of xterm. When build with --enable-next-scroll aterm
will have NeXT-ish scrollbars. They look nicer and easier in use, but have
slightly larger size. Their look and size can be tweaked at compile time
by modifying parameters in rxvt.h.
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 aterm 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
aterm 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, aterm must be installed setuid root on some systems.
COLORS AND GRAPHICS
If graphics support was enabled at compile-time, aterm 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, aterm
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.
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 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,
aterm -fg Black -bg White -rv
would yield White on Black, while on xterm(1) it would yield
Black on White.
ENVIRONMENT
aterm sets the environment variables TERM, COLORTERM and
COLORFGBG. The environment variable WINDOWID is set to the X window
id number of the aterm window and it also uses and sets the environment
variable DISPLAY to specify which display terminal to use. aterm uses
the environment variables ATERMPATH, then RXVTPATH and finally PATH
to find XPM files.
You can meet maintainers online, get support, report bugs
and make sugestions on AfterStep IRC channel:
#afterstep on EFnet.
