Since you mention it, yes. I think (but not 100% sure) that I had the case that I chose all the relevant changes to recover, but still I got the error message about a class not existing. The class creation event was not there (in the changes). It might have been an obscure case, maybe I deleted the class, and then renamed an existing one to the name of the deleted class... Something along the lines... But it's not because of that case that I wrote this utility. For me, it's just a matter of preference. I prefer not to sort through the changes, and file-in the categories I was working for. If I *do* need "recover lost changes", I know it's there. And of course this tool is only limited to the categories specified, whereas the "recover lost changes" deals with system-wide changes.

Exactly! ;-) > In a perfect world Pharo would be perfect, never crash and never loose > any data. To be fair, I have not had a VM crash in quite some time. What I do manage to archieve is to make the image unresponsive (either by halting where I am not supposed to, or introduce delays/infinite-recursions in the UI thread, etc.). Then I have to kill the VM. It is sad having to kill the VM, not being able to rescue your unsaved work. But Mariano is right, and I *am* aware of the "recover lost changes" functionality (it was not always the case though), and I would like to address his comments/concerns... > On Mon, Nov 12, 2012 at 8:42 PM, Mariano Martinez Peck > <marianopeck(a)gmail.com> wrote: > Now, I would really like to understand if this is a real need of a new tool > or a demonstration that the current tools need some improvements.

Mariano, you raise very valid points and questions. I know about the "recover lost code" functionality, and have had to use it myself a couple of times already. And was very glad and relieved after the fact! :-) When I post this, I don't do it to question or challenge core Pharo functionalities. I do it as a "user" sharing a solution that I programmed for myself, for my own uses, and hoping it might be useful for somebody else. Maybe it *is* confusing if I post something like this on the "pharo-project" mailing list. I apologize for this. Now, having said this, let me tell you that *I* (me) am not always happy with the "recover lost changes" way of recovering my changes. For one, I find it tedious to have to sort through do-its that just *might* be important, or maybe not... It takes too long, it is something that demands too much concentration from me, and a process where I can do many things wrong (what happens if I forget a couple of methods? can I be sure I didn't forget anything). And then there are the renames, class deletions, etc. On top of that, I think that not all might land on the ".changes"... I had the case where a class creation was not there... Maybe it was a class rename, or something like that. Me, if I have to decide between sorting through a long list of changes, or just doing "file-in" from a couple of files and be done in seconds, I take the latter approach ;-) Again, this is a solution I hacked for me, and am just sharing with the world :-). It's not meant as a "reconver lost changes" replacement... But I understand your concerns, and am glad you raised them. Cheers, Sebastian

Yes. So for now you simply used plain polymorph. In the future we will have a UI builder. Stef

thanks Now do you have a case where the categories get lost (because they should be saved in the change file) And we may broke something. Which version are you using?

It seems that I *was* using Spec after all :-) Only I didn't know it... At least I think so, since I defined the UI programmatically... I used information from here: http://book.pharo-project.org/book/LanguageAndLibraries/GUI/PolymorphTutori… and here: http://www.pharocasts.com/2011/02/pharo-gui-with-polymorph.html And if I understand correctly Spec and Polymorph don't compare, because Spec "uses" Polymorph (right?). 2012/11/12 Damien Cassou <damien.cassou(a)gmail.com>: > On Mon, Nov 12, 2012 at 8:06 PM, Sebastian Nozzi <sebnozzi(a)gmail.com> wrote: >> P.S. 2 -- I was amazed at how easy it was to code the UI!
