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

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.

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.

> 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

You might want to try and pretty print the complete image and see if you loose any comments or if comments are moved at the wrong place. >From within a green browser press "refactor > pretty print" and get a coffee (it takes a long time). Note that you might want to disable pretty-printing in the refactoring changes. The diff looks better with pretty printing enabled, but then this is not what you get afterwards.
