Nov. 16, 2012

Hi, I'd like to script some shell commands in Pharo 2.0. Is there any way to do that in Pharo? It seems OSProcess class is suitable but seems it's not yet fully ported in Pharo 2.0. Thanks, Roberto

Cool! It's great that now we have a way of supporting Pharo. I thought it was a bug, but realized that after signing up, you can login but you wont appear in the members list before you actually pay.

[Pharo-project] Unicode Fonts
by Sven Van Caekenberghe Nov. 16, 2012

Nov. 16, 2012

I was playing with the following: http://en.wikipedia.org/wiki/Chess_symbols_in_Unicode '/tmp/chess.txt' asFileReference writeStreamDo: [ :stream | (16r2654 to: 16r265F) do: [ :each | stream nextPut: each asCharacter ] separatedBy: [ stream space ]. stream crlf ]. $ cat /tmp/chess.txt â â â â â â â â â â â â (this shows for me, in my terminal/mail, YMMV ;-) String streamContents: [ :stream | (16r2654 to: 16r265F) do: [ :each | stream nextPut: each asCharacter ] separatedBy: [ stream space ]. stream crlf ]. Is there a way to make this work, a font selection that show these Unicode characters in Pharo ? That would be cool. I tried using Freetype font Monaco, the same as my terminal where the right characters show, but that didn't help. Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

[Pharo-project] Pharo on Android questions
by laurent laffont Nov. 16, 2012

Nov. 16, 2012

Hi, I'm happy because I've been able to put my Pharo MPD client on Android to control my Raspberry Pi sound system :) - photo: http://twitter.yfrog.com/obnq3xmj - code: http://smalltalkhub.com/#!/~LaurentLaffont/MPD Thanks a lot for this wonderful documentation: http://code.google.com/p/squeakvm-tablet/wiki/JenkinsBuilds , it feels great to start something in Pharo that works on the first try just reading the doc :) Now the questions: - the MPD client is doing lot of network operations & parsing: fetch data from MPD server, Spotify, parse JSON responses, .... It feels rather slow on the phone. What is the easiest way to measure performance of the image running on Android and detect bottlenecks ? - I remember there was a lot of discussions about remote tools some months ago. I been busy since then, is there news on this side ? - it seems it's not possible to display the app in portrait, only landscape, no automatic rotation. Confirm ? - is there a Morphic theme available that matches Android look & feel ? - is it possible to control the Menu and Back hardware buttons ? Cheers, Laurent

[Pharo-project] [ANN] Pharo Online Help 1.0
by Torsten Bergmann Nov. 15, 2012

Nov. 15, 2012

It should be a pluggable design similar to current help system so one can write in wikistyle, html, markdown, ... But we need one default. I like Markdown too - but do we have some lean code to parse or just transform it to HTML. The help system should be relative small - so it can be delivered with the default image. Dont know about current dependecies of PetitParser and friends. Bye T.

[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
