Re: sam and varios mail programs

[Rich Salz]

I modified sam so that when creating the fifo it first did
	getenv("sampipe")
and if that existed it used that as the name of the pipe.  I set that
variable in my .rcrc which is sourced by my X startup stuff.

For editing I set VISUAL to $home/bin/callsam, which is this:
#! /bin/rc
~ $#* 1 || {
    echo Usage: `{basename $0} file >[1=2]
    exit 1
}

~ $#sampipe 0 && {
    sampipe=$home/.sam.$USER
    ! ~ $#DISPLAY 0 && sampipe=$sampipe.$DISPLAY
}
! test -r $sampipe && {
    echo `{basename $0} ^ ': No pipe "' ^ $sampipe ^ '" to sam' >[1=2]
    exit 1
}

{ switch ($1) {
case /*
    echo B $1
case *
    echo B `{builtin pwd} ^ / ^ $1
} }>$sampipe

echo Type EOF when done:
cat
# Could use "sed 1q" to get just a newline but I prefer the EOF.

This is the easy part.

This is the hard part.  It happens that if I do something like this
with mush, and simply wait until I've finished with the editor, I'm ok,
but it's pretty fragile.  That's why I was wondering if someone else had
beat me to inventing this wheel.

sam and varios mail programs

[Arnold Robbins]

Greetings.  I use 'mush' as my mail program, and I have my EDITOR environment
variable set to use sam.  The problem comes when I have a sam running, and
then I go to read mail. When I edit my file, it cranks up another sam. But
when that sam quits, it removes the fifo in /tmp that the `B' command uses.
At that point, I can no longer use `B' to communicate with my orignal sam.

My question is, how do *you* handle this?  Does anyone have a shell script
that runs B on their temporary mail file such that things stay in sync
after the file is written back out with sam?

(This has probably been discussed before...)

Thanks!

Re: sam and varios mail programs

[Jonathan Shopiro]

I use mailx with sam as my editor.  I only have one instance of sam on
my workstation.  It works like this:

I invoke mailx with the following command:

	crt=50 PAGER=Bcat VISUAL=BB mailx

"crt=50" means if it's longer than 50 lines run it through the pager.

"PAGER=Bcat" means use Bcat (a shell script; see below) to display long messages.

"VISUAL=BB" means use BB (ditto) as the message editor

Then when I try to read a long message it appears in sam.  When I
compose a message I can type "~v" and the message so far appears in
sam.  I edit it until its perfect, select write, and go back to the
mailx window where I hit return and then send it.  It's a mess, really,
but it beats mailtool and textedit (no characterization sufficiently
derogatory).

Now for my question: has anybody gotten <exch> to work reliably with
sam and 9term under Solaris?  It seems to work for a while after
rebooting but then it doesn't work anymore.  I poked through the code
to some X function about swapping selections and then I gave up.  Also,
is it supposed to work to snarf in one 9term window and paste (the
snarfed text) into another?  That never works for me.

Here are the shell scripts (simple modifications of B, both of them):

Bcat:

	line="none"
	
	if [ $# != 0 ]; then

	fi
	
	dir=`/bin/pwd`
	if [ "$USER" = "" ]; then
		USER=$LOGNAME
	fi
	pipe=/tmp/.sam.$USER
	
	if [ $DISPLAY != "" ]; then
		pipe=$pipe.$DISPLAY
	fi
	
	if [ ! -r $pipe ]; then
		echo `basename $0`": No pipe \""$pipe"\" to sam." 1>&2
		exit 1
	fi
	
	cat - >$file
	
	echo "B $files" >> $pipe
	if [ $line != "none" ]; then
		echo $line >> $pipe
	fi
	
	read dummy

BB:
	#!/bin/sh
	
	files=
	line="none"
	
	if [ $# = 0 ]; then
		echo 'usage: BB [-nnnn] files...'  1>&2

	fi
	
	if [ ! -r $pipe ]; then
