Re: [Pharo-users] Nautilus plugin with new menu entries

by HernÃ¡n Morales Durand

Hi Stef, The plugin can work in Pharo 4 with a minimal modification (one line of code). Please feel free to include/change it if you like the features. No, I didn't see your enhacements because I use Pharo 3. I wish I could have more time.

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?

Re: [Pharo-users] Blitzkrieg!

by horrido

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. If you think this reflects poorly on everyone, then I apologize.

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.

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.

Re: [Pharo-users] parsing a file / stream API advice

by Johan Fabry

Hi Daniel, I have disclaimers as the 2 previous responses, this is my feeling about the matter. :-) I would prefer to think purely in terms of the API that you want to use when reading the file, and have that clear and explicit. So do NOT subclass Stream nor do a class extension with #nextFoo. I would think in terms of the Stream API when doing that, and reuse as many message names as possible, because it is a fairly âstandardâ API. So: option 1, without the use of doesNotUnderstand. > On Jan 18, 2015, at 06:11, Daniel Lyons <fusion(a)storytotell.org> wrote: > > This is an OO design question. > > For my task, I have some objects and a particular file format that encodes them.

Daniel, I don't have a definitive answer for you.

Re: [Pharo-users] Blitzkrieg!

by horrido

This is a fine line to tread. I have several problems with self-censorship: First of all, "Generalissimo" is just a handle. My previous handle, "horrido", was surely objectionable as well, since it's a play on the battle cry associated with the WWII German Luftwaffe ( Horrido: Fighter Aces of the Luftwaffe <http://www.amazon.ca/Horrido-Luftwaffe-Raymond-F-Toliver/dp/0553126636> ). I admit to being a WWII buff. I have been for many years. Should I apologize for this? Second, I am firmly and philosophically opposed to Political Correctness. I find it intellectually offensive to my very core. I guess that would make me a lousy politician. One thing that no one can accuse me of is being intellectually dishonest. Third, my self-censorship is hardly different from what Muslim terrorists were trying to achieve in Paris last week. Free expression should be protected (as long as it is not foul or vulgar). Any language you use will offend /someone somewhere/ at /some time/ in the world. I try to be sensible and I try to be artistically honest. This is reflected in my writings. There will always be people who find my style distasteful.
