## File:
## MosaicMail
## Author:
## Earl Hood ehood@convex.com
## Copyright (C) 1994, Wed Oct 26 15:00:44 CDT 1994
## Thanks:
## Roman Czyborra <czyborra@cs.tu-berlin.de> -- Whose feedback
## and sh script greatly improved the program.
##
## Description:
## MosaicMail is a simple Perl program that loads a single mail
## message from STDIN into a running Mosaic process. If no Mosaic
## process is running, the script will exec Mosaic.
## MHonArc is called to do the actual conversion of the e-mail
## message. Therefore, MIME messages will be converted.
##
## Change the values in the CONFIG section below to suit your
## needs.
##
## Notes:
## o For MH users, the following can be used to process the current
## mail message:
##
## % show -noshowproc -noheader | MosaicMail
##
## o For Trn users, you can load a newsgroup post into Mosaic
## by piping the post to MosaicMail:
##
## | MosaicMail
##
## o MHonArc needs to be in your search path
##
## o If extra files are created by MHonArc (i.e. for graphics,
## binaries, etc), they will not get removed. You'll have
## to manually remove them.

## CONFIG: Change the following variables to reflect your needs
## Location of converted message; directory must exist and be a FULL
## pathname.
$DESTDIR = "$ENV{'HOME'}/tmp";
## Set the following variable to "goto" or "newwin". "goto" will make
## Mosaic load the message into the current window. "newwin" causes
## Mosaic to load the message into a new window.
$directive = "newwin";
## Give location of mknod command for creating FIFO files to communicate
## with Mosaic.
$mknod = '/etc/mknod';
## Uncomment and set the following variable to a MHonArc resource file if
## you want to customize the format of the converted message
#$ENV{'M2H_RCFILE'} = "mhonarc.rc";

## Actual code to do the conversion (Should not have to edit)

$SIG{'INT'} =
$SIG{'QUIT'} =
$SIG{'TERM'} = 'cleanup';
## Make FIFO for html file
system("$mknod $htmlfile p") && &error("Unable to create $htmlfile: $!\n");
## Set Mosaic command to use if Mosaic is not currently running
$Mosaiccmd = "Mosaic file://localhost/$htmlfile 2>&1 > /dev/null";
if ($pid && (kill 'CONT', $pid)) { # Mosaic session active
## Set Mosaic control file
system("$mknod $tmpfile p") && &error("Unable to create $tmpfile: $!\n");
## Signal Mosaic to read control file
kill 'USR1', $pid;
## Write instructions to control file
open(MTMP, ">$tmpfile") || &error("Unable to open $tmpfile: $!\n");

}
## Convert message to HTML by using MHonArc
open(MHONARC, "|mhonarc -single -outdir $DESTDIR > $htmlfile");
print MHONARC <STDIN>;
