PROGRAM:

NAME


FvwmCpp - the Fvwm Cpp pre-processor

SYNOPSIS


Module FvwmCpp [options] filename

The FvwmCpp module can only be invoked by fvwm. Command line invocation of the FvwmCpp
module will not work.

DESCRIPTION


When fvwm executes the FvwmCpp module, FvwmCpp invokes the cpp pre-processor on the file
specified in its invocation, then FvwmCpp causes fvwm to execute the commands in the
resulting file.

INVOCATION


FvwmCpp can be invoked as a module using an fvwm command, from the .fvwm2rc file, a menu,
mousebinding, or any of the many other ways fvwm commands can be issued.

If the user wants his entire .fvwm2rc file pre-processed with FvwmCpp, then fvwm should be
invoked as:

fvwm -cmd "Module FvwmCpp .fvwm2rc"

Note that the argument to the option "-cmd" should be enclosed in quotes, and no other
quoting should be used.

When FvwmCpp runs as a module, it runs asynchronously from fvwm. If FvwmCpp is invoked
from the .fvwm2rc, the commands generated by FvwmCpp may or may not be executed by the
time fvwm processes the next command in the .fvwm2rc. Invoke FvwmCpp this way for
synchronous execution:

ModuleSynchronous FvwmCpp -lock filename

OPTIONS


Some options can be specified following the modulename:

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

-cppprog name
Instead of invoking "/usr/lib/cpp", 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. Please note that FvwmCpp will attempt to remove this file
before writing to it, so don't point it at anything important even if it has read-
only protection.

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

-lock If you want to use this option you need to start FvwmCpp with ModuleSynchronous.
This option causes fvwm to wait that the pre-process finish and that FvwmCpp asks
fvwm to Read the pre-processed file before continuing. This may be useful at
startup if you use a session manager as Gnome. Also, this is useful if you want to
process and run a Form in a fvwm function.

-noread
Causes the pre-processed file to be not read by fvwm. Useful to pre-process a
FvwmScript script with FvwmCpp.
