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_". -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 tem- porary 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 direc- tion, 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 Sta- ticGrey 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.
