Hi erik right now I do not know. I'm not sure that spec handles well coloring. Do you have an example that we can play with?

Re: [Pharo-users] Blitzkrieg!

by horrido

Excellent advice! I shall do exactly that. Again, I apologize if anyone was offended by my use of the world "blitzkrieg". I was trying to be clever and it obviously backfired on me. My love of WWII history should not paint me as a bad guy. To be honest, I had no idea that modern Germans still feel very touchy about the subject. As a Canadian growing up, my friends and I loved to play war, esp. WWII, and this has been ingrained into my character. I had a profound admiration for great tactics and strategy (which may also explain my love of chess), and there's no question that blitzkrieg ranked high in that regard.

Re: [Pharo-users] Blitzkrieg!

by Jimmie Houchin

As an USAmerican, I would not have associated Generalissimo with WWII. It is a common term for a leader in many Hispanic nations or armies. Many of them unfortunately are dictators. I also not being a WWII buff, was not familiar with horrido. It meant nothing to me and I didn't look. It was merely a label you were using to represent yourself. That is one of the interesting things about this list is it is very global in representation. So it is very difficult to know name associations that people will make. When representing ourselves we can make any choice we want, wise or not. But hopefully if we are doing something which represents some community (this or any other) we should make decisions within that context. Considering what has been learned about global perception. You might take the opportunity on your blog on an about page or something to educate as to what your chosen names represent, to you, whom they are representing. This could present an opportunity to educate on one of your favorite topics and to allow people who might otherwise have the wrong understanding to obtain the correct one for you and your context.

Best approach to multiple text colors in Spec

by Erik Stayton

I am working on a client in Pharo for which I want to be able to color different pieces of text in different colors (the text stream I'm receiving has ANSI escape codes, and I'll be parsing those and coloring the text appropriately for display). But I have not been able to figure out how to get text color to appear. I set up a simple UI in Spec, using a TextModel for my display. To see if coloring worked, I sent updates to the display via: textToAdd := TextMorph new contents: (Character linefeed asString, text asString). displayField pendingText: (textToAdd textColor: Color lightBlue). displayField accept. I would expect to see the text appear in lightBlue, but it all appears black just like before. Anyone know the solution to coloring text inside Spec widgets?

You make some valid points. I shall reconsider my position. However, the articles I write, such as "The Smalltalk Revolution" and "Dart is Dead", as well as my "stream of consciousness" blog at Tumblr, must remain true to my style. Artistically, I have no choice. I'd like to make one further note: the handle Generalissimo was NOT selected from the Italian army during WWII. So no one should take offence here. It was used in an excellent Chinese film called " Back to 1942 <http://www.imdb.com/title/tt2113822/?ref_=nm_flmg_act_12> ", which impressed me so much that I glommed onto the handle.

Re: [Pharo-users] Blitzkrieg!

by Jimmie Houchin

I do not think anybody is trying to compel you to be politically correct or intellectually dishonest. However, most of what you have been doing is being done in the name of marketing. When marketing you choose what words you use and what words you don't use. You choose in order to effect a certain result. The words you choose have consequences. From the handle you choose to label yourself by, to the words you choose to describe Smalltalk or Pharo. You are a free person, living in a free part of the world. You make your choices for your words. And you accept the consequences of those choices. Whether for accolades or rebuke or somewhere in between. However, in this context you are also attempting to represent a larger community. You are attempting to represent and market Smalltalk and Pharo. There are many here who are a part of that community will also bear the consequences of words chosen by members of this community. To my understanding all that is being asked is. Look at the big picture. Choose your words, handles, labels wisely. Is it politically correct or intellectually dishonest to call you Richard? Can you not be intellectually and artistically honest and choose words for who you are and who you are writing to and for? Are there no other handles which are just as appropriate for you but are better in this context? I think it can often be just as intellectually dishonest to say, "tough", "deal with it". I like these words and I do not want to make an effort to choose others. It is not the English language that constrains. Regarding Paris. My heart and prayers go out to the people of France. You are not writing political satire. You are attempting to make certain technical, business, policy, ... arguments to market the adoption of Smalltalk and Pharo. You are not being attacked at all. You are simply being advised of consequences to certain choices. Choose. Choose well. For the consequences good or bad, are yours.

As part of that we need a data structure that holds scopes, for variables but also for other things. It turns out that for the variables part we can map rather nicely to classes, which gives us a bunch of advantages. So for each scope I generate a class. The scope keeps that class in a âvarsâ instance variable (there are never any instances of these classes BTW). When the scope is garbage collected I want to remove the class from the system. So I put #finalize in the scope with the idea to remove the class, but it turns out that âvarsâ is always nil. So in the end it did not work out ... > > You're probably registering the scope for finalization before setting the vars insvar? > The shadow copy is made at the point of registration, so any subsequent assignments to the scope's instvars is not accounted for. Yes! Silly me :-/ that was the problem! Thanks for pointing it out! Itâs still not perfect: when running the tests +-half of the generated classes are not removed, but maybe the test runner still holds some references. As I said before, I donât have much time to spend on this â¦ I will need to make some time to investigate more later. ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile
