Example of ServerInfo
by Lic. Edgar J. De Cleene 29 Nov '05

29 Nov '05

http://200-122-104-133.cab.prima.net.ar:8085 The page what informs about official Weather on Rosario is very slow to load Is a very bad ad for SGI , maybe they have a pentium 100 for run the site. Hopes this example was useful to some squeaker.

Re: Newbie Question on Text Input

Roger: The only thing what I know similar to you wish is in Pavel Krivanek kernel image, showing text input and code result output in same window. Similar to a Unix Console or Terminal. Maybe he post his code. Edgar

Newbie Question on Text Input
by Roger McDermott 29 Nov '05

29 Nov '05

Hi I've just joined this list and I have a question regarding getting input into Squeak. I would say at the outset that I am a novice programmer (although I have used some Smalltalk before and know a little Java) so I apologise if this is a bit basic. I appreciate that one can use the Transcript window to give simple screen output from code run in the Workspace but is there a similar (ready-made) window that can be used to get input? In one of the Java packages that I use there is a class called a ConsoleWindow which allows input and output in the same window, e.g. ConsoleWindow c = new ConsoleWindow(); c.out.println("Please input an integer"); myInteger = c.input.readInt(); c.out.println("Your integer times two is" + 2 * myInteger); In private emails, Ken Rose pointed towards the Workspace window (but unfortunately I am not adept enough to get that to work in the way I want) and Stephane Ducasse gave me the following code snippet | res | res := FillInTheBlank request: 'please enter a number'. res asNumber. which does allow things to be input but the FillInTheBlank object disappears as soon as you enter a number. I'm sure that there is a very simple way of doing this but, at present, it is still unclear to me. Any help would be much appreciated. Roger McDermott

Web photo viewer
by Lic. Edgar J. De Cleene 29 Nov '05

29 Nov '05

I wish have a Web photo viewer using HttpView HVTransientView subclass: #HVRandomPhoto instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'HV-examples' default | listaArchivos image myStream choose dirName | dirName := 'Discovery:Users:admin:Pictures: Rosario:'. "here I select my starting photo folder" listaArchivos := (FileDirectory on: dirName) entries select: [:ea| ea isDirectory not]. " I wish files, not directories " listaArchivos := listaArchivos copyWithout: (listaArchivos at: 1). "this is OS X , not a photo " choose := (listaArchivos atRandom) name. myStream := (FileStream readOnlyFileNamed: dirName,choose) binary. image := Form fromBinaryStream: myStream. myStream close. image :=image scaledToSize: 360 @ 270. image borderWidth: 2 fillColor: Color red. ^image Copy of old Comanche Form asWebImage | aStream | aStream _ RWBinaryOrTextStream on: ''. GIFReadWriter putForm: (self asFormOfDepth: 8) onStream: aStream. aStream reset. ^ MIMEDocument contentType: MIMEDocument contentTypeGif content: aStream This works , but dithered. Changing form depth don't help. Changing mtethod to: asWebImage | aStream writer | aStream := RWBinaryOrTextStream on: ''. writer := PNGReadWriter on: aStream. [ writer nextPutImage: self ] ensure: [writer close]. ^ MIMEDocument contentType: MIMEDocument contentTypeGif content: aStream Don't work I wish if any have advices as how I could do this. The service is running at http://200-122-104-133.cab.prima.net.ar:8084/ and you could see Rosario city photos. Thanks in advance.

SM server cache preloaded etc
by goran＠krampe.se 29 Nov '05

29 Nov '05

Hi people! Ok, managed to get the SM server cache preloaded yesterday. The whole of SM (all releases of all packages) ended up as 54Mb zipped. :) This means hopefully that server outages for the original URLs will not be a problem anymore. Or people accidentally "removing" published files. Transcript will show if SM ends up falling back on the server cache. For this "boot strap" I simply assumed that the files accessible that I managed to download *are correct* so I used their checksums. During this I also produced a list of releases that currently fail download - I will post my findings later and CC the people involved. And right, I also repaired the URLs for the uploaded files that are hosted on the SM server itself - they now begin with "http://map.squeak.org/" instead of "http://map1.squeakfoundation.org". regards, Göran

Squeak Map setup
by Jimmie Houchin 29 Nov '05

29 Nov '05

Hello, Will the code used for Squeak Map be made available on Squeak Map soon? The latest updates to KomHttp and HV? Can I install via MC with the packages at http://squeak.krampe.se/ ? If so what packages, what order? I've tried but when I tried to run the HV examples I got an error about root. I then went to SM and tried to download the latest there and then upgrade to the MC packages. But I get an EOCD error with KomHttpServer. Any advice to get the latest setup running greatly appreciated. Jimmie

Where does a font change "go"?
by Jim Rosenberg 28 Nov '05

28 Nov '05

I have a class of my own which is a subclass of TextMorph. When I select all the text and change the font with command-k it visibly works. Now I am trying to find where this is recorded using the morph explorer, and I can't find it. (This is under Squeak 3.6.) Now, it's clear the explorer is hiding things from me. E.g. when I open up text in the explorer, it does not show me the instance variable runs, but if inspect text it does. What actual method is being applied when I make a font change with command-k? I need to be able to recover enough to generate a snippet of Smalltalk code to be able to recreate the font change. -Thanks, Jim

Re: How to produce application package with code and media
by Chris Muller 28 Nov '05

> Monticello is a great tool to transport application code however it does > not help to include media (graphics and sound) with the code in one > single archive. > > What is your experience with that? > > Including the media inline in the code? or any other solution? SAR is one option. You could include the media files in the SAR. Magma might be another option. A Magma repostory is (simultaneously) a Monticello repository. In this way, users can load/merge code directly from there before connecting and accessing the "content" contained in that repository. However, I say "might" because large media streams >10MB are not suitable for a Magma repository; they are probably best left in their own files to remain quickly accessible via file-sharing services.. - Chris

[BUG]SyntaxErrorNotification class(Object)>>doesNotUnderstand: #inClass:withCode:doitFlag:
by p.provoost＠rn.rabobank.nl 28 Nov '05

Hi, I am changing the default text font in image 6703. Tha same thing happens in 6704. After the error shown below, the TOOLS flap is gone. It makes no difference to which font I try to change. Even a change to the same original font produces this walkback.

TryCatch
by Damien Cassou 28 Nov '05

28 Nov '05

Hi, How can I try/catch for errors in Squeak ? I didn't find anything. I would like to do something like : [ aPieceOfCodeThatCanThrowsExceptions ] catch: [:exception | Transcript show: exception] or self try: [ aPieceOfCodeThatCanThrowsExceptions ] catch: [:exception | Transcript show: exception] thank you -- Damien
