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 .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 fvwm -f "FvwmM4 .fvwmrc". Note that the argument to the option "-f" should be enclosed in quotes, and no other quoting should be used. For example, a typical invocation might be
fvwm -f "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
-
Lets you pass an option to the m4 program.
- -m4-squote
-
Lets you change the m4 start-of-quote character to character.
- -m4-equote
-
Lets you change the m4 end-of-quote character to character.
- -m4prog
-
Instead of invoking "m4", fvwm will invoke name.
- -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 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.
- FVWMDIR
-
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.
