[Pharo-project] settings integration

by Alain Plantec

Dear list, I'm about to integrate some settings in replacement of some preferences, and I would like to have your opinions about the way. The new setting package make it possible to completely separate a setting value from the setting browser. In fact, the setting browser package should be removeable without any modification elsewhere. As an example, let's consider the #annotationPanes preference. The only mandatory thing is that there is a class variable or an instance variable of a singleton in the package which owns the setting along with corresponding get/set accessors. For #annotationPanes, I define the #BrowsersHaveAnnotationPane class variable in CodeHolder. In addition, I define CodeHolder class>>browsersHaveAnnotationPane and CodeHolder class>>browsersHaveAnnotationPane:. In order to be able to manage this setting from the setting browser, we have to define a setting declaration for it. Because the setting browser must be removeable, I would create a new package for it. Let's Tools-Base-Settings be this new package which then includes the CodeHolderSettings class with the following declaration: CodeHolderSettings class>>browsersHaveAnnotationPaneSetting <setting> ^ (SettingManager newSetting: 'Show annotation pane' translated) parent: #codeBrowsingSettingNode; default: false; target: CodeHolder; setSelector: #browsersHaveAnnotationPane:; getSelector: #browsersHaveAnnotationPane; description: 'If checked then the annotation pane is shown in browsers; it is dynamically updated with useful informations about the code which is currently browsed' translated Is it ok like that ? Thanks Alain

Lukas, Glad to hear your code is safe. I am aware of the recover lost changes feature, and have been helped by it once or twice, but I find it cumbersome compared to Ian's Chunk Browser; he did a wonderful job with it, and archives of the Dolphin groups are full of testimonials.

Re: [Pharo-project] (no subject)

by Schwab,Wilhelm K

Lucas, I do not expect magic, but I do expect it to work, and failing that, candor re limitations. IMHO, the real problem has been a sort of XP snobbery: it appears that those building or integrating what would otherwise be a wonderful tool, have zero interest in preserving comments, and even some contempt for those of who write them. It is far easier to impugn those suggesting improvements than to make it work or to inetegrate fixes. I will spare you second-hand comments about what has been done in other languages and editors, as I have never encountered an RB anywhere but Smalltalk. I am perfectly happy using the RB only for things where it does not reformat. If it turns out that #promptOnRefactoring meets my needs and/or if format-preservation works, I will extend my use accordingly. Thanks for working on it.

However, you are the first person involved with the RB to ever mention it to me. Â Previously, I was simply told that commenting methods is a waste of time and I would be happier and healthier if I would change my misguided ways. Don Roberts and John Brant improved the refactoring engine a lot in 2002. I assume that there was some pressure from the VisualWorks and Dolphin folks. Unfortunately Squeak and Pharo people were stuck with the refactoring code from the last century. >Â Obviously, I take a different view of it, and all the more so having recently ported a lot of aging code to Pharo; comments saved my skin yet again.

Re: [Pharo-project] Safe and Quit can be dangerous

by Schwab,Wilhelm K

Lukas, I wish you good luck in recovering your work; hopefully the change log will allow you to avoid losses. Perhaps a toolsmith among us can take a look at Ian Bartholomew's Chunk Browser for Dolphin and do something similar on Pharo; it is a very helpful tool. Another one I would like to see is Ghoul, which provides a debugger-like view of Dolphin's crash logs. Not at all to say "I told you so," I have been arguing against save+quit for years, precissely because I was shafted by it in the past. That was on Smalltalk/V, but I have been skiddish about it ever since. If something bad happens post-save, you have no chance to fix it. In your case, the image might have melted down anyway, so good backups and recovery tools are a must.

Re: [Pharo-project] (no subject)

by Lukas Renggli

> Interesting news about #promptOnRefactoring. However, you are the first person involved with the RB to ever mention it to me. Â Previously, I was simply told that commenting methods is a waste of time and I would be happier and healthier if I would change my misguided ways. Don Roberts and John Brant improved the refactoring engine a lot in 2002. I assume that there was some pressure from the VisualWorks and Dolphin folks. Unfortunately Squeak and Pharo people were stuck with the refactoring code from the last century. >Â Obviously, I take a different view of it, and all the more so having recently ported a lot of aging code to Pharo; comments saved my skin yet again. Â If the RB can be made to respect them, I will eagerly use it. I think the situation is much better now, but you cannot expect magic. Lukas -- Lukas Renggli http://www.lukas-renggli.ch
