FvwmM4(2.0)                                                        FvwmM4(2.0)



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.  Not really needed as
              any unknown options will be passed on automatically.


       -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.


       -outfile
              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/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.
