[Glass] run topaz from bash and have access to arguments from topaz smalltalk

[Ralph Mauersberger]

Hi Mariano,

to access the arguments from inside topaz you can use a feature of most 
unix shells called "here document". This concept allows you to embed a 
document inside your shell script which gets passed to stdin of any 
executable:

executable <<LimitString
firstCommand
nextCommand $1
LimitString

The document is surrounded by any given string. The shell itself will 
substitute the environment variables and replace them by there values 
before the document is passed to the executable.

So use something like the following:

#!/bin/bash

if [ -z \$1 ];
then
    echo "argument expected"
fi

topaz -l <<EOF
set gems $STONENAME user Username pass TopSecret
login
printIt
'$1' printString
%
exit
EOF


You used "run" inside your script which is a normal "do-it". I replaced 
it by "printIt" because I assume that you are interessted in the 
evaluated expression.

Topaz has a directive called input. Use that to load other code or if 
you don't like the login credentials hardcoded in the script:
input $MYAPP_CONFIG/mylogin.topaz

Hope that helps.

Br,
Ralph
