FvwmCpp






FvwmCpp − the FVWM  Cpp pre‐processor

FvwmCpp is spawned by fvwm, so no command line invocation will work.


When called, this module will attempt to have /usr/lib/cpp pre‐process the file
specified in its invocation, and then have fvwm read the resulting file.


FvwmCpp can be invoked by inserting the line ’FvwmCpp’ 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 FvwmCpp, then fvwm should be invoked as:


     fvwm2 ‐cmd "FvwmCpp .fvwm2rc"


Some options can be specified on the command line:

‐Cppopt
     Lets you pass an option to the cpp program.  Not really needed as any
     unknown options will be passed on automatically.


‐Cppprog
     Instead of invoking "/lib/cpp", 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 Cpp to be retained. This file is
     usually called "/tmp/fvwmrcXXXXXX"



FvwmCpp 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.









                                       ‐2‐


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 Cpp, 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.

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