FvwmM4(1)FvwmM4(1)NAMEFvwmM4 - the FVWM M4 pre-processor
SYNOPSISFvwmM4 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.
INVOCATIONFvwmM4 can be invoked by inserting the line 'FvwmM4' in the .fvwmrc
file. It can also be called from a menu or mouse binding. If the user
wants his entire .fvwmrc file pre-processed with FvwmM4, then fvwm
should be invoked as:
fvwm2 -cmd "FvwmM4 .fvwmrc"
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 } .fvwmrc"
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 temporary 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/fvwmrcXXXXXXXXXX"
CONFIGURATION OPTIONSFvwmM4 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 direction, 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 StaticGrey 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.

AUTHORFvwmM4 is the result of a random bit mutation on a hard disk,
presumably a result of a cosmic-ray or some such thing.
