[Pharo-project] Moving XMLSupport to Smalltalk
by Usman Bhatti Feb. 15, 2013

Feb. 15, 2013

Hello, We are moving Moose to SmalltalkHub and once the projects in Moose moved and tested, we will port Moose to Pharo 2.0. Stef has volunteered to move XMLSupport to SThub and update configs for both Pharo 1.4 and Pharo 2.0. What do you think because it is important to have XMLSupport on a reliable repo. Usman

[Pharo-project] monkey stuff
by Camillo Bruni Feb. 15, 2013

Feb. 15, 2013

I changed the monkey to run all tests, so the integration process will take considerable more time but at the same time will hopefully catch more bugs. The first complete check is already running here: https://ci.inria.fr/pharo/job/Pharo-2.0-Issue-Tracker/10550/console

[Pharo-project] Another stupid question
by Torsten Bergmann Feb. 15, 2013

Feb. 15, 2013

This was just an example to play with since you asked for a #convertFromBase:to: method in your original mail and one cant provide such a method on Number. Your original request 11 convertFromBase: 2 to: 10 may work - but it wont work for hex values: FF convertFromBase: 16 to: 10 then FF would have to be a string. 'FF' convertFromBase: 16 to: 10 So having a #convertFromBase:to: on String is not to recommend (especially since the string has to be in a number format) and also not necessary. I should have added this to my mail as a warning. Just use (Number readFrom: self base: sourceBase) printStringBase: targetBase If necessary put it in a private helper method for conversion. May I ask why you require conversions between the different base systems? Working on a hex editor for Nautilus? ;) Bye T.

[Pharo-project] Opening a webbrowser (using NB on non-Windows)
by Torsten Bergmann Feb. 15, 2013

Feb. 15, 2013

In Pharo 2.0 one can now use NBWin32Shell shellBrowse: 'http://www.pharo-project.org' which will open an external webbrowser on the given URL. This is currently limited to Windows. Anyone able to implement/call appropriate NB functions for Mac and Linux? I would like to see a unified interface coming with 2.0 NBWebbrowser shellBrowse: url dispatching to the appropriate class depending on OS. Since these days a lot of work is done using webbrowsers I think a unified way to open a browser on a given URL is required for Pharo. I also need this for the upcoming Pharo online help to work on all major platforms. Thanks T.

[Pharo-project] TxTextMorph based on new text model

In a case study on designing a document editor in 'Design Patterns (1995)' , there is a reference to a thesis from 1993 showing that using Flyweight or sharing commonality makes it fast enough. I assume that was c++, but 20 years of hardware improvements should be enough. Paul R Calder. Building User Interfaces with Lightweight Objects.

But we don't need to show more than one screenful at a time. I noticed the current strategy seems to be to make a very simple model work, and add abstractions late. That means a lot of refactorings will be needed. Cocoa fundamental abstractions are TextStorage, LayoutManager, TextContainer and TextView. LayoutManager uses TypeSetter(s) to layout glyphs in lines according to the dimensions of one or more text container objects in one or more text views, directs the GlyphGenerator to translate characters in the textstorage into glyphs...

Sven wrote: >So something like this should work: > > (Integer readFrom: 'FF' base: 16) printStringBase: 2 Integer readFrom: 'FF' will not work since #readFrom: expects a string in decimal representation and 'FF' is hexadecimal. It also wont work for large numbers due to sending it to "Integer". Just use (Number readFrom: '16rFF') printStringBase: 2 which works for large numbers (Number readFrom: '16rFFFFFFFFF') printStringBase: 2 Bye Torsten

>Euh, sure this works: > (Number readFrom: 'FF' base: 16) printStringBase: 2 Yes, one has to use "Number" instead of Integer and #readFrom:base: #readFrom: works too if you already have the string in source base representation, e.g. '16rFF'. The timing is good - currently work on the literal section for the new Pharo help system and will integrate this as an example in the tutorial. Bye T.

Hi guys, I know it sounds stupid but how do I convert numbers from one base to another ? I found 3 printStringBase: 2 -> '11' But I would like something like 11 convertFromBase: 2 to: 10 -> 3 The Finder did help me about this one so I ask here :) Thanks in advance, Ben
