Command Line Squeak/Scripting: Status?

Hi everyone!

I'm curious about what the status of a Squeak setup for scripting is,
specifically for Linux? My end goal is being able to tell a user or
run programmatically from another script a Squeak script by typing
something like:

./hallowelt.sq

where hallowelt.sq is a file like-

#!/usr/bin/squeak -filein
Transcript show: 'Hello World'; cr.

I also would really, really like, the ability to pass command line
arguments, so:

./hallowelt2.sq Aaron

#!/usr/bin/squeak -filein
Transcript show: 'Hello World ';
show: (Argv at: 2);
cr.

I don't need anything very fancy, nor do I need a certain version of
the image or much in the way of library support. The one library I do
need is PostgreSQL suport. In my newish job, I'm starting to move
various reports that pull data from a super flexible object-
relational database setup from Java to Python. I'd like to do this in
Squeak, obviously! But due to a few factors, the first couple I've
done are in Python. I don't need to do any elaborate stuff, I don't
need a curses interface, etc. I'm fine with most of it all being in
the image, with the hallowelt.sq file in this example being nothing
other than something that runs the squeak VM but some how tells the
image to run a certain script through a command line argument. I'd
do development on a regular Squeak VM on my Mac, then deploy to the
server where someone else would run the reports.

Worst case I could roll this myself, skipping commandline arguments
and using config files that the report-runner has to edit to specify
the date range rather than just doing it on the command line. But I'd
rather a more Unix-feeling solution. I personally don't need anything
like input and output through pipes, but I might find a use for them
later if the option was there.

So, what's up with Squeak for this sort of setup? What are my
options? Do I have any useable ones?

Regards,
Aaron

You can pass (and access) command line arguments in squeak - I do it all
the time in my headless images.

Look at implementers of #getSystemAttribute:

This is what the beginning of my startup method (class-side) looks like:

startUp: resuming

| parameter |
resuming
ifFalse: [^self].

parameter := Smalltalk getSystemAttribute: 2.
parameter isNil
ifTrue: [^self].

parameter asLowercase = '-runmission'
ifTrue: [
self runMission.
Smalltalk quitPrimitive].

...

Then you need to register whatever class that method is implemented in:

initialize

Smalltalk addToStartUpList: self

Run the initialize method, and then save and quit.

Later,
Jon

Mathieu should release sapphire soon but he got a tooth problem.
And I would love to have clients that complain :)

What is Sapphire? I haven't heard of this one. Didn't see it on google or
squeaksource either.

If one of these functions well enough to run programs from a script, let me know
and I'll be glad to add Squeak to the "Computer Language Shootout"
(http://shootout.alioth.debian.org).

If need be, we can generate a squeak image with the benchmark classes in it,
save the image, and run the script using the image. We do this for the Lisp
and GNU Smalltalk implementations.

Thanks Philippe,

For the time being you can use it but if you want to use the shell
you have to compile or get the OSProcess plugin.
However, on bug still remains when you declare classes. So, if you
want to define method the class should be already in the image.

I hope I can fix it this weekend and build a little web page to
explain how to use it. Then I will give you the link to some pre-
prepared image .

Try "man squeak", or on Debian, "man squeakvm". There are
instructions on how to do it down under the "Scripts" section.

The simplest thing is to make a file with the Smalltalk code and then
another script that has:

squeak squeak.image thescript.st

However, you can also make self-contained script files. Here's a
simple example fromthe man page, though I'm sure with some cleverness
you can come up with more ideas.

#!/usr/bin/squeakvm --
Transcript cr; show: ’Hello, world’.

Now, this basically all works, but be warned that there are a lot of
rough edges. Nobody programs like this, and so nobody has polished
it. For example, the last time I checked, error messages are not
handled gracefully.

Re: Command Line Squeak/Scripting: Status?

And in 3.9 thescript.st has to have the full path or url to the file.
