Hi, I have programming experiences with BASIC compilers. I would like to program in a Smalltalk environment; but I have the following newbie's questions: a) Can I deploy an image without all the browsers and other "stuff" - just a plain console program? b) How is it possible to write a console program without gui etc.? Thank you! Roland.
Hi Roland, Can you be more certain? Is your main goal to interact with a final product because you do not have gui (for example web service). Or you just want to develop some application that can be used only with command line etc... Cheers. Uko ÐадÑÑлано з iPhone 16 ÑеÑп. 2013 о 21:33 Roland Strasser <rolstra@gmx.at> напиÑав(ла):

Hi Roland, Welcome to Smalltalk. As someone who started with BASIC in the early 1970s, I have seen a few changes in the past 40 years. As you have discovered, the typical Smalltalk experience has a heavy emphasis on a GUI. As to deployment, it is generally more difficult to take things out (browsers, tools, etc.) in Smalltalk than in other environments where there is a more rigid distinction between development and deployment. The first thing to note is that any Pharo image can be deployed with command line arguments that disable the GUI (-vm-display-null and -vm-sound-null). Sometimes we just let the other "stuff" come along for the ride and get ignored. Why go to the trouble to remove it? Next, there is GNU Smalltalk (http://smalltalk.gnu.org/), "The Smalltalk for those who can type"! Check it out. Finally, GemStone/S (http://gemtalksystems.com/index.php/products/gemstones/) is available as a command-line Smalltalk with no native GUI. Let us know what you want your console application to do and we can give more advice. James On Aug 16, 2013, at 11:33 AM, Roland Strasser <rolstra@gmx.at> wrote:

Yes, it is perfectly possible to use Pharo Smalltalk to write command line tools. It even works pretty well. But you definitively should use the IDE/GUI during interactive development or you'll miss out on a lot !

Hello everybody, Primarilly I just want to catch some experiences with SmallTalk - which so far I find really exceptional. For doing that I just want to use a simple input-/output window (could be a 'transcript'?), for something like that: input value calculate return value If a gave this image to somebody else, I find it necessary to just give the "program" itself, without all the rest of the image (and ide). Thanks, Roland -- Mag. Roland Strasser
Hi, to make you more familiar with existing pharo applications you can check out: http://www.drgeo.eu/ Also Pharo is used for web development. You can follow Sven's tutorial to make some simple web app: http://zn.stfx.eu/zn/build-and-deploy-1st-webapp/ Cheers.

Thank you, Dr. Geo is a full blown-up application. So far I do not intend to write soemething like that. Morely I intend to use as less GUI as necessary/possible. Just simple input-/output in a console window or something like that. But maybe BASIC or Pascal is more suitable for that? Roland. -- Mag. Roland Strasser

I would not see why :) You define a package with classes and then use --eval to invoke your class and a message pharo yourimage.image --eval '1+3' prints 4 and this is exactly doing that read this chapter even if it is more general
Hi roland You can run pharo with a UI using the headless mode. in that case you can implement a simple read eval loop that read from standard input and write on stdout. You can also use the -eval command line parameter to get a value of a message Now you can also define a simple ui and disable all the tools. This requires a bit more practice. So let us know. There is also the user manager package that let you control some behavior. Stef

Thanks, is there any tutorial how to write a GUI window with menues, dialogues etc? It would be very helpful, because Smalltalk is VERY different to other languages (as you know of course). Thanks Roland. -- Mag. Roland Strasser
There is a tutorial but we should finish it using Spec https://pharo.fogbugz.com/default.asp?W67 We are planning to write a complete one but benjamin should come back from holiday. Note that the difference is not between Smalltalk and X, Y Z the difference is between graphical frameworks: for example in VisualWorks you write application GUI differently than in VisualAge or Pharo.
