mailing-list for TeXmacs Users

While exploring TeXmacs some more and playing with the
mycas example, I noticed that the shell session in
TeXmacs doesn't really facilitate interactive use..
for instance, the current directory reverts to the
TeXmacs cd after each command. 

So, I coded a simple TeXmacs interface for bash. The
interface itself is a bash script which uses bash's
eval feature to provide more complete shell access.

This method has limitations too, but it is sufficient
for providing a bit more robust shell.. and it works
right now :)

It might be possible to hook bash directly into
TeXmacs without modification by using a suitable init
script and a special PS1 prompt.

But for now, here is the script: 

#!/bin/bash
function nextinput
{
        COUNTER=$[$COUNTER+1]
        echo -ne "\002"; echo -n "channel:prompt"; echo -ne
"\005"
        echo -n "bash($COUNTER)] "
}

echo -ne "\002"; cat << EOF
verbatim:
GNU bash $BASH_VERSION
EOF

nextinput
echo -ne "\005"

while true; do
        read buffer
        if [ "$buffer" = "exit" ]; then
                echo -ne "\005"; exit
        fi

        echo -ne "\002"; echo -n "verbatim:"
        eval $buffer
        
        nextinput
        echo -ne "\005"
done
