[Pharo-project] yielding to command line
by Tudor Girba Nov. 15, 2012

Nov. 15, 2012

Hi, I have the following requirement: - I start an image from the command line with an initial script - I want to wait until the Smalltalk script finishes until I can continue with the command line script - But, I do not want to stop the image I can achieve the first two points by having the image quit at the end. Is there a way in which I can somehow continue the command line execution without stopping the image? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

[Pharo-project] [Pharo-Project] About new TxText text model
by Denis Kudriashov Nov. 15, 2012

Nov. 15, 2012

Hello. I look deep at TxText package where Igor and Camillo introduced new text model. Text model based on sequence of span objects. There are now two kind of spans: CharacterSpan and LineSeparator. Each span has reference to next and previous spans. There is TxSelection object which contains cursor. So you can insert new text at cursor, you can cut selection, replace selection with another text. Such maniulation changes text model structure. It can create new span objects. It can split current span at cursor position, It can remove selected spans. Also you can move cursor up, down, left, right. Cursor always know about current span and span position. I like design :). And I want use this package. And I have questions and suggestions: 1) Cursor is end of selection object. So now when you move cursor selection changed, because start of selection stay same. Am I right? I think cursor movement should always reset selection. It is what we see with basic text editors. But cursor now is just instance of TxPosition which implements simple position protocol (move left, up...). It just change current span and span position by movement. TxPosition knows nothing about TxSelection object. That's why I think Cursor class should be introduced here which alway reset text selection by any move. And if you want to change selection bounds just get explicitly start or end of selection and use position api. What do you think? 2) Next question about changes notification of text model. First I want Cursor and Selection objects are annnouncers. So I can implement CursorPresenter and SelectionPresenter to show such objects and handle changes. For example when CursorMovedAnnouncement happen I can move cursor caret morph at appropriate position. Another idea is make span objects announcers. Maybe it is not good idea but I want to subscribe at SpanAdded, SpanRemoved. SpanChanged, SpanSplitted. With such events I can make very simple implementation of TextEditor as list of SpanMorph's. Maybe it is not optimized solution but I think it is most simple thing. So I want to try it. 3) What about auto wrap behaviour? If you have auto wrap option at text editors you have line width restriction. And you should spit real lines of text to visual lines which satisfed this restriction. And text mode should know about such restriction because any text insertion can require new visual lines creation. I think insertion single line text at span position should be executed by special "restriction object". It should return new characters of span which satisfied that restriction. And it should return new span object (or just remains characters) which will present new visual lines. Then this "remains characters" should be inserted to next span at 0 position. When wrap behavior not needed "restriction object" just inserts new text into current characters at given position and returns result. If you agree about such logic please suggest good name for such "restriction object" and instance variable where it will placed (at TxModel I think) Ok, now what do you think about all this? I want implement all my suggestions. But first I want listen your opinions. Best regards, Denis

[Pharo-project] Is the one-click image *really* self contained?
by roberto.minelli＠usi.ch Nov. 15, 2012

Nov. 15, 2012

Hi all, Since this morning every time I open Pharo 2.0 an error pops out. Here's the full trace: Parser>>notify:at: Parser>>expected: Parser>>braceExpression Parser>>primaryExpression Parser>>messagePart:repeat: Parser>>expression Parser>>statements:innerBlock:blockNode: Parser>>statements:innerBlock: Parser>>method:context: Parser>>parse:class:category:noPattern:context:notifying:ifFail: in Block: [methNode := self method: noPattern context: ctxt]...etc... BlockClosure>>on:do: Parser>>parse:class:category:noPattern:context:notifying:ifFail: Compiler>>translate:noPattern:ifFail: Compiler>>evaluate:in:to:notifying:ifFail:logged: Compiler class>>evaluate:for:notifying:logged: Compiler class>>evaluate:for:logged: Compiler class>>evaluate:logged: DoItDeclaration>>import CodeImporter>>evaluateDeclarations in Block: [:decl | value := decl import] OrderedCollection>>do: CodeImporter>>evaluateDeclarations CodeImporter class>>evaluateFileStream: FileReference(AbstractFileReference)>>fileIn in Block: [:stream | CodeImporter evaluateFileStream: stream...etc...

Cheers, Roberto

[Pharo-project] Render images - Porting from Cincom VW to Pharo
by Torsten Bergmann Nov. 14, 2012

Nov. 14, 2012

>It's a web application so I've got several WAComponent instances The #asPackagedString: is VW specific and not available in Pharo. In Seaside on Pharo the resources like pictures are stored in methods returning a ByteArray with the bytes only. There is an easy way: just save the original resources from VW (for instance the JPG) in a folder and then reimport them again into the Pharo based Seaside image. Example: So you are using Seaside and have a subclass of WAFileLibrary for your own resources (for instance MyFileLibrary) Just open http://localhost:8080/config/files and select the Library (here "MyFileLibrary") and click on "Configure". Now you can upload the JPG again using the web interface and Seaside is (re)generating the method on class MyFileLibrary which should look like logoJpg ^#(1 2 3 ...) asByteArray containing the bytes that represent the JPG. If you have more than one you should note that the superclass of WAFileLibrary which is WAAbstractFileLibrary in latest Seaside provide some utility methods to automate importing of resources. Check for #addAllFilesIn: and #addFileAt: on the class side. Bye T.
