Hi guys,
I have a some questions about program execution:
If I have a text file with some smalltalk code, is it possible to execute that code from the outside of the VM graphical interface?
I'm looking a java like execution. Java as smalltalk use a VM to execute the code, but the way java execute the program, some people don't even know this. Due to the nature of smalltalk I don't know if what I'm asking is possible.
-- these are other questions I have ---
How are applications deployed in smalltalk?
Once I have the image I can see how things are implemented. How do you do hide implementation that probably don't want other to see? Is there something written about this that you can suggest? I'm just looking to decrease my smalltalk ignorance.
I really like this language, and I'm wondering day after day, what cause its extinction, I've read about what java did and that stuff, but I think there should be more than marketing stuff. The questions I'm asking are some the reasons I see that prevent me to use smalltalk on my day to day job, are these reason the cause that this great language(system) is not being used more widely?
Thanks, Erlis
I don't know whether can Squeak do it, but in GNU Smalltalk this is the standard model of execution of programs (GNU Smalltalk doesn't have GUI, it is Ruby- or Python-like interpreter, but with Smalltalk VM).

Hi Erlis,

If you specify a .st file in the command line to Squeak, it will be executed. If you end the script with
SmalltalkImage current snapshot: false andQuit: true
Squeak will close after execution. In a recent image it may be Smalltalk instead of SmalltalkImage current. I have no 4.2 handy.

Googling Squeak headless will help you to make squeak run without any visible UI. Assuming this was your question :-)

Again only a rough sketch:
Smalltalk addToStartupList: MyClass will run MyClass class side startUp: on startup.
At minimum you should disable the preferences to warn if no changes file and to warn if no sources file. You can completely disable the programmers facilities of Squeak, but then you can't debug into a faulty image.
Use any installer builder (NSIS seems to be preferred by Windows Squeakers, I used Inno Setup), to unzip your folder and create a desktop or menu shortcut.
You can search Squeak dev or Squeak beginners on deploy, it's a FAQ.

Disable Programmer facilities as described before. See my post here on Jan 1st 2011 on "image not locking down" for details.
In theory you can debug any image file from another running image, don't know if the tools readily exist. But then for dotNet assemblies these tools seem to exist.
Hi Herbert,
Thanks a lot for your reply! You have addressed all my concerns.
