FvwmCommand(1) FVWM Modules FvwmCommand(1)
NAME
FvwmCommand - FVWM command external interface
SYNOPSIS
FvwmCommand [-cmrvw] [-S name] [-i level] [-f name] [-F level] [com-
mand...]
DESCRIPTION
FvwmCommand lets you monitor fvwm transaction and issue fvwm command
from a shell command line or scripts. FvwmCommand takes each argument
as a fvwm command. Quotes can be used to send commands including
spaces.
FvwmCommand 'FvwmPager 0 1'
INVOCATION
FvwmCommandS should be spawned once by fvwm, either in .fvwm2rc file,
from menu, or from FvwmConsole. From then on, FvwmCommand can be
called from a shell or script to execute fvwm commands.
From within .fvwm2rc file:
Module FvwmCommandS
or
AddToFunc StartFunction "I" Module FvwmCommandS
Then, in script file or from shell:
FvwmCommand 'popup Utilities'
OPTIONS
-c Informs FvwmCommand to read multiple commands from the standard
input instead of the one command specified in the command line
arguments. This disables -m or -i.
(echo "Exec xload"; echo "Beep") | FvwmCommand -c
-F <level>
Specifies the level of fvwm window flags FvwmCommand outputs.
0 No window flags will be printed.
2 Full window flags will be printed if information level, -i
option, is 2 or 3.
-f <name>
Specifies an alternative FIFO set to communicate with a server.
The default FIFO set is /var/tmp/FvwmCommand-${DISPLAY}C, in which
FvwmCommand..C is used to send commands and FvwmCommand..M is to
receive messages. FvwmCommandS must have been invoked with the
same <name> as its first argument prior to FvwmCommand invocation.
Alternatively, option -S can be used. Refer option -S. This option
-f is useful when a dedicated connection is necessary to run a
background job while another connection is kept for interactive
use.
-i <level>
Specifies the level of information that FvwmCommand outputs.
0 Error messages only.
FvwmCommand -i0 FvwmBanner
will show a banner without any output. On the other hand,
FvwmCommand -i 0 foobar
will return,
[FVWM][executeModule]: <<ERROR>> No such module
´foobar´ in ModulePath '/usr/lib/X11/fvwm'
Note that Fvwm doesn't return any error messages in cases like
below since 'windowid' itself is a valid command.
FvwmCommand -i 0 'windowid foo bar'
1 Errors and window configuration information. This is the
default.
FvwmCommand send_windowlist
Information like below will show up.
0x02000014 window FvwmConsole
0x02000014 icon FvwmConsole

0x00c0002c icon file xemacs.xpm

end windowlist
The first column shows the window ID number, which can be used
in 'windowid' command. The second column shows the information
types. The last column shows the information contents. If no
information is returned, add -w <time> or -r option. This
might be needed in heavily loaded systems.
2 Above and static window information.

3 All information available.
FvwmCommand -i3 'Killmodule Fvwm*'
This will report which windows are closed.
0x03400003 destroy
0x02400002 destroy
-m Monitors fvwm window information transaction. FvwmCommand continu-
ously outputs information that it receives without exiting. This
option can be used in a background job often combined with -i3
option in order to control windows dynamically.
FvwmCommand -mi3 | grep 'iconify'
It will report when windows are iconified or de-iconified.
Note: FvwmCommand does not block buffer its output but many utili-
ties such as grep or sed use block buffer. The output of the next
example will not show up until either FvwmCommand is terminated or
stdout buffer from grep is filled.
FvwmCommand -mi3 | grep ' map' |
sed 's/\(0x[0-9a-f]*\).*/windowid \1 move 0 0/'
Instead, use tools with buffer control such as pty or perl. The
below will iconify new windows when opened.
Fvwm -mi3 | perl -ne '
$|=1;
print "windowid $1 iconify\n" if /^(0x\S+) add/;
´ > ~/.FvwmCommandC
-r Waits for a reply before it exits. FvwmCommand exits if no infor-
mation or error is returned in a fixed amount of time period.
(Refer option -w.) The option -r overrides this time limit and
wait for at least one message back. After the initial message, it
will wait for another message for the time limit. This option is
useful when the system is too loaded to make any prediction when
the system is responding AND the command causes some message to be
sent back.
-S <name>
Invokes another server, FvwmCommandS, with FIFO set <name>.
If -f option is not used with this option, the invoking FvwmCommand
uses the default FIFO to communicate the default server to invoke a
new server.
If -f option is used with this option, the invoking FvwmCommand
uses the default FIFO to communicate the default server to invoke a
new server. Then, switch the FIFO set and start communicating the
new server.
This option -S is useful when a dedicated connection is necessary
to run a background job while another connection is kept for inter-
active use.
If the <name> is a relative path name, that is relative from where
fvwm is running, not from where FvwmCommand is invoked.
-v Returns FvwmCommand version number and exits.
-w <time>
Waits for <time> micro seconds for a message. FvwmCommand exits if
no information or error is returned in a fixed amount of time
period unless option -m is used. The default is 500 ms. This
option overrides this default value.
WRAPPER
FvwmCommand.sh has bourne shell function definitions to keep the syntax
similar to fvwm configuration file. This file is to be sourced:
. FvwmCommand.sh
DesktopSize 5x5
FvwmCommand.pm is for perl in order to keep the syntax similar to fvwm
configuration file. Commas can be used to separate fvwm commands'
arguments.
use FvwmCommand;
if( $ARGV[0] eq 'home' ) {
Desk 0,0; GotoPage '1 1';
}elsif( $ARGV[0] eq 'jump' ) {
Desk "0 2"; GotoPage 0, 1;
}
Although arguments in FvwmCommand are not case sensitive as fvwm, the
functions defined in FvwmCommand.sh and FvwmCommand.pl are case sensi-
tive.
ERRORS
If the following error message show up, it is most likely that FvwmCom-
mandS is not running.
FvwmCommand error in opening message fifo
--No such file or directory--
Fvwm modules don't return error messages to fvwm but output on stderr.
These error messages will not be shown as FvwmCommand messages.
FvwmCommand is an interface to send commands to and receive information
from Fvwm2 from processes which are not Fvwm modules.
EXAMPLES
test1.pl - takes 1 argument 't' to invoke FvwmTalk
'td' to kill FvwmTalk
'' to move windows
test2.sh - takes 1 argument 'b' to invoke FvwmButtons
'kb' to kill FvwmButtons
'r' to change # of button rows
'c' to change # of button columns
ex-auto.pl - auto raise small windows. It will keep them visible.
ex-cascade.pl - cascade windows, then move them back.
ex-grpmv.pl - choose a group of windows to move together.
Above examples are not meant to be practical but to show how it can
be done.
focus-link.pl
This is a user programmable window focus script.
Default behavior is:
1. When a window is opened up, focus the window and move the
pointer
to it. The parent window regains focus when a window is
closed.
Parenthood is determined when a window is opened. It is the
last
focused window with the same X class.
2. #1 would not occur to AcroRead opening window.
3. #1 would not occur when SkipMapping is set and the window is
the
only window of its class.
4. For Netscape find dialog window, addition to #1, resize the
window
to 300x150 pixels and move it to East edge of the screen.
Download/upload windows will not be focused nor be in focus
link
list.
5. Move appletviewer to NorthWest corner.
6. Xterm won't focus back to its parent after closed.
7. When a window is de-iconified, focus it and move the pointer.
focus-Netscape.pl
Focuses pop-up windows, such as 'open URL' or 'find' whenever
opened up. This let the user to type in immediately without
moving mouse. This script also moves 'download' window to the
right edge to keep it visible. If this is invoked from
.fvwm2rc, use as:
AddToFunc "StartFunction" "I" Module FvwmCommandS
+ "I" Exec $HOME/scripts/focus-Netscape.pl
push-away.pl <direction> <window name>
Pushes windows away to avoid overlapping. use as:
push-away.pl up 'Fvwm Pager'
