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

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

Hi guys,

In Norbert's utilize, we have this nice script runTopazScript.sh :

#!/bin/sh

source $APPLICATION_DIR/env

if [ -z \$1 ];

then

   echo "no script name given"

fi

cat ../scripts/login.st \$1 | su -m $GEMSTONE_USER -c \"$GEMSTONE/bin/topaz -ql -T200000 \" 

That let us automatically connect to GemStone using an auto-generated .topazini. So we can pass around a topaz script and that would be execute. So we can do for example:

sudo sh ./runTopazScript.sh something.tpz 

Now....I saw in several topaz scripts from seaside that the SMALLTALK code is able to directly access the argument variables to the shell. For example, startSeaside30_adaptor does:

GsFile gciLogServer: '$1 Server started on port ', $2 printString.

I want to do the same in my something.tpz. Imagine I have this something.tpz file:

run 

$1 printString.

%

And I execute:

sudo sh ./runTopazScript.sh something.tpz mariano

So how can we adapt the script so that such a smalltalk script outputs 'mariano' instead of the literal string $1 ?

I tried adding a  & at the end of the topaz call and many other workarounds but I am not sure if topaz needs something special for this. 

Thanks a lot in advance and sorry for the offtopic.

Mariano,

that should be correct and it works for me. I tested with the following two scripts:

test.sh with the following lines:

#!/bin/bash
topaz -ql <<EOF
input $1
EOF


and input.topaz like this:

set gems seaside user DataCurator pass swordfish
login
printIt
20 factorial
%

I can execute "bash test.sh input.topaz" and get the result.

Just as addition and independent of the here documents approach: Another way to access the shell script arguments would be to export them to the environment and access them via System>>gemEnvironmentVariable:. So the following should also work:

#!/bin/bash
export MYARG=$1
topaz -l <<EOF
set gems seaside user DataCurator pass swordfish
login
printIt
'The first argument was: ', (System gemEnvironmentVariable: 'MYARG')
%
exit
EOF

The here document is just to make the example complete. This way you can access the env vars from within any method.

Br,
Ralph

Any ideas?

Thank!

Hope that helps.

Ralph

$2 factorial
%

And then call it like this:

 "bash test.sh input.topaz 20"

I would like to do that without having to export each variable individually...  maybe using $@ somewhere?

 

Just as addition and independent of the here documents approach: Another way to access the shell script arguments would be to export them to the environment and access them via System>>gemEnvironmentVariable:. So the following should also work:

exit

Ok,  (System gemEnvironmentVariable: 'MYARG') is answering nil ... however.....System performOnServer: 'echo $MYARG'  does answer correctly. 

weird...

Hmm, I don't think that there is a way to get something like that directly working. Of course there are workarounds, like storing $2 to a file, save it to sessionState or whatever and afterwards access it from within input.topaz with appropriate smalltalk code.

I forgot to said....somehow that works for startSeaside30_Adaptor.... but I don't understand how it can do it.

Maybe I'm blind, but I can't see any special trick in startSeaside30_Adaptor. It's just one here document passed to "cat", the result is piped to topaz. $1 and $2 are used inside the here document and are substituted by the shell like we discussed it. $1 and $2 are also used to specify the log file name.

 

Just as addition and independent of the here documents approach: Another way to access the shell script arguments would be to export them to the environment and access them via System>>gemEnvironmentVariable:. So the following should also work:

#!/bin/bash
export MYARG=$1
topaz -l <<EOF
set gems seaside user DataCurator pass swordfish
