CR and LF in Text files
by jowen 24 May '09

24 May '09

I have a simple list of items in a text file with "Enter" separating. When I read them into a Set the first item in the list is picked up differently to later occurrences of the same thing. Hence, one too many items in the "Set". Inspecting shows that later items are proceeded by a linefeed character which is why they end up different to the Set than the first. What am I doing wrong? The same thing works fine in VisualWorks. Thanks. -- View this message in context: http://www.nabble.com/CR-and-LF-in-Text-files-tp23690584p23690584.html Sent from the Squeak - Beginners mailing list archive at Nabble.com.

MonticelloBrowser question
by Ch Lamprecht 23 May '09

23 May '09

Hello, could anybody help me to understand, how to use MonticelloBrowser? (Working with 3.9 #7067) I read SBE and it says: " The right-hand pane lists all of the source-code repositories that Monticello knows about, usually because it has loaded code from them. If you select a package in the left pane, the right pane is filtered to show only those repositories that contain versions of the selected package." However, I don't see that happen. If I select e.g. OmniBrowser in the left pane, the list in the right pane is reduced to a local path on my filesystem (the package-cache). But if I deselect all in the left pane to see all the repositories in the right pane, then select 'http://source.wiresong.ca/ob' and open the repository I get a browser containing lots of newer version of OmniBrowser (and other packages). Now these repository browsers always take some time to load and I have to check different repositories by hand to find the latest version. What is the right way to search (and update) to the latest release of a package? Thanks for your help, Christoph

Concatenating strings stored in an ordered collection
by Paul DeBruicker 23 May '09

23 May '09

Hi I've created an ordered collection of strings. I'd like to paste each element of the ordered collection together into one long string that contains all of the elements of the ordered collection. So given this: | col | col := OrderedCollection with: 'asdf' with: '1234' with: 'aaaa'. I'd like to end up with this: 'asdf1234aaaa' I've come up with this: | col | col := OrderedCollection with: 'asdf' with: '1234' with: 'aaaa'. String streamContents: [:stream | col do: [:i | stream print: i]] but that gives: '''asdf''''1234''''aaaa''' What else should I do? Thanks Paul

Starting on the Mac

I've downloaded squeak on my Macbook Pro (OS-X). When I launch the .app, the menu says "Squeak VM" and a file dialog box opens. What is it asking for? Where's the Squeak desktop? There is nothing useful on the Squeak VM menu. -Ken

My goal was to implement more fully the Gif98A spec. What I found was that I needed a morph to emulate the gifs virtual screen and to control the display of the individual images. What I wound up with was a variant of image morph that had a #step method which waited for a timer to time out then hid a submorph and showed the next. The hiding and showing I encapsulated in a #singleStep method so that I could also choose to manually (via menu command) go from one morph to the other. So for your purposes you would need each slide to be a morph. Embed all the morphs into the virtual screen morph which would be either transparent or a background color. The create the singlestep and step methods. All morphs respond to #hide and #show. All objects respond to #stepTime. I used the steptime of each submorph to determine how long between singleSteps. Hth, Yours in curiosity and service, --Jerome Peace

Processing a file at image startup (scripting)
by Cédrick Béler 19 May '09

19 May '09

Hi, While delivering a small app (a project scheduler), people asked me if it's possible to execute it by a command line without opening an image. I have a pseudo-dsl to define a project (collection of tasks) that the app is scheduling and so, what I'd like is launching the app by passing a file as parameter. Then squeak "open headless", process the entry file, write an outputfile with results and eventually errors, and exit. I did something but this is a terrible hack :) I'd like to have other idea on that. If we consider: squeak -headless test.image file.in According to the vm man, file.in must be a script (st file with bang notation). I'm not aware of a way to pass a plain text file. So I just hacked ProjectLauncher>>startUpAfterLogin (this is where I get a dnu if passing a file as parameter) so that my file can be processed and the image closed afterwhile. Can people point me a better way of doing that ? My feeling is I need to create a ScriptClass that has a startUp method where file processing can be implemented. Thanks -- Cédrick ps: a related question would be which startUp classes are not necessary if we only need to process a File (do we need InputSensor, etc...)

I can't reproduce the problem. Can you isolate the relevant code and upload? Or produce an specific example of the problem that can be reproduced? The reason I didn't look into the question you asked was that there was not enough info. The first rule of trouble shooting is first hand information. No sense trying to guess the answer.
