FvwmM4(1) FvwmM4(1)
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 .fvwm2rc
file. It can also be called from a menu or mouse binding. If the user
wants his entire .fvwm2rc file pre-processed with FvwmM4, then fvwm
should be invoked as:
fvwm2 -cmd "FvwmM4 .fvwm2rc"
Note that the argument to the option "-cmd" should be enclosed in
quotes, and no other quoting should be used. For example, a typical
invocation might be:
fvwm2 -cmd "FvwmM4 -m4-squote { -m4-equote } .fvwm2rc"
Some options can be specified on the command line:
-m4-prefix
I think this makes all the m4 directives require the prefix
"m4_".
-m4-prefix-defines
Causes built-in defines to be prefixed with "m4_" (i.e., m4_HOME
is defined instead of HOME, etc.)
-m4opt option
Lets you pass an option to the m4 program. Not really needed as
any unknown options will be passed on automatically.
-m4-squote character
Lets you change the m4 start-of-quote character to character.
-m4-equote character
Lets you change the m4 end-of-quote character to character.
-m4prog name
Instead of invoking "m4", 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
FvwmM4 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 m4 to be retained. This file
is usually called "/tmp/fvwmrcXXXXXX"
-lock If you want to use this option you need to start FvwmM4 with
ModuleSynchronous. This option causes fvwm to wait that the pre-
process finish and that FvwmM4 asks fvwm to Read the pre-pro-
cessed 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 FvwmM4.
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.
HOME The home directory 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.
SCREEN The screen 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 default visual class, e.g. PseudoColor.
COLOR Yes or No, Yes if the default visual class is neither StaticGrey
or GreyScale.
FVWM_CLASS
The visual class that fvwm is using, e.g. TrueColor.
FVWM_COLOR
Yes or No, Yes if the FVWM_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.
FVWM_MODULEDIR
The directory where fvwm looks for .fvwmrc and modules by
default, as determined at compile time.
FVWM_USERDIR
The value of $FVWM_USERDIR.
SESSION_MANAGER
The value of $SESSION_MANAGER. Undefined if this variable is not
set.
