NAME
FvwmM4 - the FVWM M4 pre-processor
SYNOPSIS
FvwmM4 is spawned by fvwm, so no command line invocation
will work.
DESCRIPTION
When called, this module will attempt to have M4 pre-process
the file specified in its invocation, and then have fvwm
read the resulting file.
INVOCATION
FvwmM4 can be invoked by inserting the line 'FvwmM4' in the
.fvwm2rc file. It can also be called from a menu or mouse
binding. If the user wants his entire .fvwm2rc file pre-
processed with FvwmM4, then fvwm should be invoked as:
fvwm2 -cmd "FvwmM4 .fvwm2rc"
Note that the argument to the option "-cmd" should be
enclosed in quotes, and no other quoting should be used. For
example, a typical invocation might be:
fvwm2 -cmd "FvwmM4 -m4-squote { -m4-equote } .fvwm2rc"
Some options can be specified on the command line:
-m4-prefix
I think this makes all the m4 directives require the
prefix "m4_".
-m4opt option
Lets you pass an option to the m4 program. Not really
needed as any unknown options will be passed on
automatically.
-m4-squote character
Lets you change the m4 start-of-quote character to
character.
-m4-equote character
Lets you change the m4 end-of-quote character to
character.
-m4prog name
Instead of invoking "m4", fvwm will invoke name.
-outfile filename
Instead of creating a random unique name for the tem-
porary file for the preprocessed rc file, this option
will let you specify the name of the temporary file it
will create.
-debug
Causes the temporary file create by m4 to be retained.
This file is usually called "/tmp/fvwmrcXXXXXX"
CONFIGURATION OPTIONS
FvwmM4 defines some values for use in the pre-processor
file:
TWM_TYPE
Always set to "fvwm".
SERVERHOST
The name of the machine running the X Server.
CLIENTHOST
The name of the machine running fvwm.
HOSTNAME
The hostname of the machine running fvwm. Generally the
same as CLIENTHOST.
OSTYPE
The operating system for CLIENTHOST.
USER The name of the person running fvwm.
VERSION
The X11 version.
REVISION
The X11 revision number.
VENDOR
The X server vendor.
RELEASE
The X server release number.
WIDTH
The screen width in pixels.
HEIGHT
The screen height in pixels.
X_RESOLUTION
Some distance/pixel measurement for the horizontal
direction, I think.
Y_RESOLUTION
Some distance/pixel measurement for the vertical direc-
tion, I think.
PLANES
Number of color planes for the X server display
BITS_PER_RGB
Number of bits in each rgb triplet.
CLASS
The X11 visual class, ie PsuedoColor.
COLOR
Yes or No, Yes if the display class is neither Sta-
ticGrey or GreyScale.
FVWM_VERSION
The fvwm version number, ie 2.0
OPTIONS
Some combination of SHAPE, XPM, NO_SAVEUNDERS, and M4,
as defined in configure.h at compile time.
FVWM_MODULEDIR
The directory where fvwm looks for .fvwmrc and modules
by default, as determined at compile time.

FvwmM4 is the result of a random bit mutation on a hard
disk, presumably a result of a cosmic-ray or some such
thing.
