How to create a red box with text in a big font?
by Tim Mackinnon Sept. 6, 2014

Sept. 6, 2014

Hi guys - Iâm a bit stumped on how to create things in big text with a set background colour. I thought I understood - but it just doesnât seem to work. I was thinking I could create a container morph, set its background colour (which works), and then put a StringMorph inside it with a set font. This last bit I canât get to work - I can do bold, but not a bigger font size. Iâve tried different things but am missing the magic sauce - can someone spot my mistake? Below, Iâve tried using a font name that I can see in the Pharo settings dialog but it doesnât work? I also tried using LogicalFont with no success either. tMorph := StringMorph new. font1 := LogicalFont familyName: 'Arial' pointSize: 24. tMorph contents: 'Hello World'; fontName: 'Open Sans' size: 24; emphasis: TextEmphasis bold emphasisCode. bMorph := Morph new color: Color red; addMorph: tMorph. bMorph openInWorld.

Using Playground on Pharo 3.0
by PBKResearch Sept. 5, 2014

Sept. 5, 2014

Hello I have been playing with Moose 5.0 (Pharo 3.0 update: #30854) on Windows 7 Pro, trying to copy and paste code from e-mails in another thread. However, if I open a Playground (which is what I get when I click 'Workspace' in the World Menu), I find that the right click menu does not have any options for copy or paste. The window responds to Ctrl-C and Ctrl-V as expected, so I can get round it, but it is inconvenient. I have checked older versions (e.g. Moose 4.9), and there the Workspace has a full right click menu. Did I do something wrong in downloading Moose 5.0 (on 23 Aug 2014)? I am a beginner with Pharo, so any help would be appreciated. Peter Kenny

It would be a worthwhile initiative because it would make collaboration much easier for other projects too. I'm interested in looking into this. I have the impression there are many more users of Glorp who are very silent on the list (I know some) Stephan

Encoding CJK URL?
by Wowerat Dirk Sept. 4, 2014

Sept. 4, 2014

My code to download some UTF8 text with japanese kanji from an url: url := 'http://www.hatinosu.net/onsen/import.kml' asZnUrl. url_string := url retrieveContents. url_string class. ByteString Now the japanese parts of url_string are unreadable. What I need is WidString and not ByteString. On linux I "solved" the problem with this workaround. download := 'wget -O /tmp/file.tmp "http://www.hatinosu.net/onsen/import.kml"'. OSProcess thisOSProcess waitForCommand: download. fs := FileStream fileNamed: '/tmp/file.tmp'. string := fs contents. fs close. string class. WideString How do I do this without extern programms?

Problems Pharo 3.0 & Windows 8.1 (64 Bit)
by volkert＠nivoba.de Sept. 4, 2014

Sept. 4, 2014

Dear all, i have problems with Pharo 3.0 under Win 8.1 (64 Bit). When i quit Pharo and then restarting the it, Pharo-VM and Windows hangs. After some time (2-3 Minutes), the Pharo VM File Dialog opens. From time to time the Windows Desktop (!) crashes and restarts. No Problems under Windows 7. Looks like a Problem with the VM. Has someone else seen this behavior under Win 8.1?

Date text converter/formatter
by Esteban A. Maringolo Sept. 3, 2014

Sept. 3, 2014

Does exist an "user friendly" Date text converter and/or formatter package? I'd like to specify the format of certain dates, in the way you normally do this, it is... with a string such as 'dd/mm/yyyy' or 'dd/mmm/yyyy'. Date's #printOn:format: expects a different parameter, which seems really convoluted. [1] And because I'll convert back and forth from/to String I'd like to know if there is a parser (other than DateParser). Thank you! Esteban A. Maringolo [1] compared with popular casting/formatting functions found in other languages/dialects

[Article] Reddit.st - In 10 Cool Pharo Classes
by Sven Van Caekenberghe Sept. 3, 2014

Sept. 3, 2014

Hi, I published another introduction/tutorial article Reddit.st - In 10 Cool Pharo Classes Implementing a Reddit style web application in Pharo using Seaside, Glorp and PostgreSQL https://medium.com/@svenvc/reddit-st-in-10-cool-pharo-classes-1b5327ca0740 The focus is not so much on the smaller size or the higher developer productivity in Pharo, but more on the fact that we can cover so much ground using such powerful frameworks, as well as the natural development flow from model over tests and persistence to web GUI. This is a more intermediate level article that assumes basic knowledge about Pharo (language and IDE). https://ci.inria.fr/pharo-contribution/job/Reddit/ http://www.smalltalkhub.com/#!/~SvenVanCaekenberghe/Reddit Enjoy! Sven PS: This article is actually an update of an article that I wrote in 2010 and that became unavailable/outdated. -- Sven Van Caekenberghe Proudly supporting Pharo http://pharo.org http://association.pharo.org http://consortium.pharo.org
