FvwmCpp(6)

the FVWM Cpp pre-processor

NAME

FvwmCpp - the FVWM Cpp pre-processor

SYNOPSIS

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

DESCRIPTION

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.

INVOCATION

FvwmCpp can be invoked by inserting the line 'FvwmCpp' 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 FvwmCpp, then fvwm should be invoked as "fvwm -f /usr/lib/X11/fvwm/FvwmCpp

Some options can be specified on the command line:

-Cppopt

Lets you pass an option to the cpp program.

-Cppprog

Instead of invoking "/usr/lib/cpp", fvwm will invoke name.

-debug

Causes the temporary file create by Cpp to be retained. This file is usually called "/tmp/fvwmrcXXXXXX"

CONFIGURATION OPTIONS

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.

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.
