[ANN] ConfigurationOfOpenDBXDriver in MetaRepoForPharo20

by Guillermo Polito

Hi! I just took some time to load and test opendbx in 2.0, with the latest fixes to be able to load ffi. The configuration stable version loads cleanly in Pharo 2.0 and the configuration is available in the configuration browser. I'll continue with Glorp & friends following :) Guille

Re: [Pharo-users] Pharo 2.0 debugger strange behavior

by Xavier MESSNER

Hi, Thanks for the information. I just discovered that i can use #haltOnce and #halt to stop execution and view step by step what happening. Highlighting is working fine this way. Thanks to smalltalk community a video exist here <http://www.jarober.com/blog/blogView?showComments=true&printTitle=ST_4U_270…> . I can migrate my code and use it daily now. I think i will have a lot of fun :) Regards.

I also notice you can use arrowDown and arrowUp, but not really helping if the list is long :) I propose a fix here: https://pharo.fogbugz.com/default.asp?10531 Ben On May 5, 2013, at 4:50 AM, DeNigris Sean <sean(a)clipperadams.com> wrote: > I'm having difficulty expressing a one-to-many relationship in a Spec UI (in Pharo 2.0). > I want to have a dialog where the user can enter a business expense, which will be assigned to a particular account (see screenshot). > > I tried: > - using a DropListModel.

After a bit of experimentation :) As an example here, I take DropListExample On the DropList when you type something like 'Gr', nothing is shown but the list actually highlight it (in green -> second selection). So if then you press enter, it selects it. That's quite weird :) I will have a look of how to have the same behaviour without having to press enter and without having to duplicate the list code Ben On May 5, 2013, at 4:50 AM, DeNigris Sean <sean(a)clipperadams.com> wrote: > I'm having difficulty expressing a one-to-many relationship in a Spec UI (in Pharo 2.0). > I want to have a dialog where the user can enter a business expense, which will be assigned to a particular account (see screenshot). > > I tried: > - using a DropListModel.

Spec One-to-many

by DeNigris Sean

I'm having difficulty expressing a one-to-many relationship in a Spec UI (in Pharo 2.0). I want to have a dialog where the user can enter a business expense, which will be assigned to a particular account (see screenshot). I tried: - using a DropListModel. This disrupted the flow because it seems it can't be typed into, so the user has to mouse through to find the correct account - using a TextInputFieldModel with entry completion. It seems that this suffers the same fate as above. In its current form, it's almost unusable. Pressing the down arrow to select an item from the completion menu makes the menu disappear, tab makes the widget lose focus, and I have complete on enter disabled, so again one must mouse click on the menu What would be the best way to express this without forcing the user to take their hands off the keyboard? Thanks! Sean

Hello, You can also find an short example of back propagation algorithm implemented in Smalltalk in chapter 21 of "Advanced Smalltalk" written by J. Pletzke.

Re: [Pharo-users] Pharo 2.0 debugger strange behavior

by Marcus Denker

Hello, The problem is that the breakpoint mechanism is implemented extremely naivelyâ¦ (I once already suggested, no, urged, to remove it because it is just not good enough). Now in addition, the machinary for finding what to highlight is *extremely* complicated in the old compiler framework. The good news is that we have a new framework nearly ready in 3.0 that solves all of thisâ¦including *real* breakpointsâ¦ this is in active development and will be ready soon. But as it is a quite radical change, this is of course for 3.0 only. Now the problem is that nobody is willing to look at debugger highlighting related issue in the old framework. (there was a bug open for 4 yearsâ¦ with quite some brave people burning a lot of time without a solution). I want to spend all energy and time to finish the new oneâ¦ I just don't think that putting effort in the old Debugger is time well spend. Breakpoints there are not yet working at all in the new frameworkâ¦ but they will at soonish. I might even remove the old implementation, it's really just a bad hack and it was amazing that it worked at all.
