Hello ...
by Mayuresh Kathe Sept. 7, 2014

Sept. 7, 2014

A hello to Pharo-Users list members. I am Mayuresh Kathe from Mumbai, India. I used to work with Squeak a while (14 years) back, but ever since I had to move over to non-OOP environments, and never did get to work with Smalltalk or alike systems ever since. To add to that, I haven't been programming for over 7 years due to being pushed into the management track. I have quit the management world, and along with it a regular job. Am now a consultant, mostly to Web startups which leaves me with a lot of spare time to tinker around with what I would really like to. After a lot of searching and experimenting, I finally landed in Pharo land, and things look good. :) Given the fact that I haven't written a single fully functional program in 7 years, I feel like I've lost the ability to code, sort-a rusty. Would the list members be kind enough to suggest a book I could work through to warm myself up to OOP? I stumbled upon "The Object Oriented Thought Process" by Matt Weisfeld, looks good, but if there's anything better suited to Pharo, would be nice to know. Thanks, ~Mayuresh

timing problem
by Werner Kassens Sept. 6, 2014

Sept. 6, 2014

Hi, i ran a program that did some calculations for about an hour. in between i occasionally moved the cursor (so that the computer did not go to sleep) and probably clicked occasionally on the browser. after some time this resulted in several errors from the browser (the program itself does nothing with the browser). when i tried to reproduce this, the program ran flawlessly (i retried it in 4.0., as i thought it happened there but perhaps it happened in 3.0, and btw it was much faster in 4.0 than in earlier versions). now i wonder whether i should regularly cede some time to other processes, and if yes, how does one do that? werner

Weakness
by Ben Coman Sept. 6, 2014

Sept. 6, 2014

I'd like to learn a bit more about the implementation of Weak objects. For example, I see... Magnitude>LookupKey>Associaton >> key: aKey value: anObject key := aKey. value := anObject Magnitude>LookupKey>WeakValueAssociaton >> key: aKey value: anObject key := aKey. self value: anObject Magnitude>LookupKey>WeakValueAssociaton >> value: anObject self at: 1 put: anObject Magnitude>WeakKeyAssociation >> key: aKey value: anObject self basicAt: 1 put: aKey. value := anObject The class definitions don't look any different to normal? I can see that the weak classes are doing an #at:put: for their respective weak attribute, but lots of non-weak classes also use that. So what is it that makes WeakValueAssociaton & WeakKeyAssociation weak ? cheers -ben

Hi everyone! When loading a package via Monticello, while compiling methods it gives an error: Syntax Error: Cannot store into and then a method. What does it mean?

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

Re: [Pharo-users] Pharo Glorp 1.7 <-> VisualWorks

Francois wrote: >I have no idea how complicated this can be. I'm a bit reluctant to dive into this if we are only 2-3 people to use Glorp in Pharo. 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

Hi, I just started using a Macbook pro with retina display. I notice the fonts are quite blurry. Is there something one can do to improve that? Johan
