Yep, I get the same results (sodbxtestu.db is populated, and the constraint error on 2nd attempt). I've been able to define a couple of classes / tables with foreign keys and it is all working fine. I'm still to set up a many-to-many relationship and the more complex queries, but it is all looking good so far. I have seen one other problem with UDBC-SQLite3: if a connection is open when the image is saved, it must be manually closed and re-opened after the image is opened. Should this be handled automatically? If you think this should be working I'll put together some code to reproduce it. Thanks! Alistair

spotter usage - a rough analysis of categories

by Tudor Girba

Hi, Juraj, Andrei and I did a rough analysis collected from 94 computers over the past 7 months. Of these, only 42 recorded more than 9 sessions so we only focused on these. It can be because the rest switched off the data collection in the meantime. We also excluded the computers of the GT team members. Of these 34 used the dive-in feature. That is, these users used at least one contextual search. We looked at the event of acting on an element (pressing Enter), and we collected the parent category. Acting on an item indicates that intent of search. There are 35 categories used in total, with 8 being used by 10 people (25% of the studied population) or more. Below you can see also the amount of computers using it: 'Classes'->40 'Implementors'->38 'History'->34 'Menu'->24 'Packages'->23 'Messages'->19 'Catalog Projects'->12 'Instance methods'->10 'Senders'->9 'Pragmas'->6 'References'->5 'Playground named pages'->5 'Playground cached pages'->4 'Help topics'->4 'Examples'->3 'Super instance methods'->3 'Selectors'->3 'ws.stfx.eu'->2 'GitHub Baselines'->2 'Dirty Monticello packages'->2 'Class methods'->2 'Global variables'->1 'All subclasses'->1 'Example Subjects'->1 'Files'->1 'Monticello Repositories'->1 'Metacello Configurations'->1 'Class instance variables'->1 'Items'->1 'Tags'->1 'Help contents'->1 'Monticello Package'->1 'Instance variables'->1 'Productions'->1 'Methods'->1 Also, in this analysis, some of the categories appear also at deeper levels (Senders, Implementors, References, Instance methods). As expected, Classes and Implementors are on top. Yet, the third is History, and it is also interesting to see that there is a high usage of a search through the World menu elements, but also of the Packages. We also note that there is quite a long tail, and this seems to confirm the hypothesis that different people have different needs and that these differences should be supported by the IDE. This analysis was carried out using the code that Juraj and Andrei put together for analyzing the data from the event recorder.

Re: [Pharo-users] Spec Drag n Drop and broken ListModel family

by Peter UhnÃ¡k

Hi, 1) this is caused by this line in "listIntConfiguration" dragTransformationBlock: [ :item | item asInteger ]; you are dragging a symbol c, but "#c asInteger = nil" 2) dragging the number converts it into a StringMorph which obviously isn't in the original collection. This is quite [expletive], because each list behaves differently: * ListModel the passenger is the object converted to a Morph, * IconListModel (a subclass of ListModel) has as a passenger IconListItem that holds reference to the original object * FastTableModel (a subclass of ListModel) will just break down on drag * MultiColumnListModel (a subclass of ListModel) won't even launch * NewListModel breaks down on drag * TreeModel has a different API, but also breaks down on drag Fun, ain't it? 3) probably similar to (2), didn't have the energy to investigateâ¦ *NOW:* In general, the drag and drop behavior, the API, and the overall behavior is broken to a various degree and inconsistent between ListModel, it's children and related classes (TreeModel, NewListModel). Last week I was working on a File Dialog replacement https://github.com/peteruhnak/file-dialog and the brokenness and inconsistencies were really frustrating. I don't see a point in trying to write a book about this particular section because it's really bad right now. Of course not having a dedicated maintainer of Spec makes life a lot harder, as people that work with/on Spec generally invest into Spec at their own time discretion (me included), so while bugs can generally be fixed, there's really no systematic effort in cleanup and API harmonization. With Stef we started to clean up and rethink it a bit when I was in Lille because there's a lot of things we don't like or should fix, but that's a long-term plan. We need a more immediate solution for the current mess. -_- *TL;DR:* 1. imho no point in documenting this stuff _right now_ 2. it's seriously broken 3. we need to clean it up and harmonize first Peter On Thu, Jun 9, 2016 at 3:52 PM, Marion Noirbent < ms.noirbent(a)etudiant.univ-lille1.fr> wrote: > Hello > I would try to integrate the exemple Drag n Drop from > http://spec.st/docs/drag_n_drop/ at the tutorial Building UI with Spec, > so I have create a class in Pharo to try them and modify the code. > > I have found some of problems, I'm not sure if it come from strange > configuration (i think about dragTransformationBlock: ), but it appear > on the both version (my class and the original code). > > Marion, > > 1) > Reproduce: > Deplace the 'c' in the list of int, try to replace the 'c' in the list > of char > Error "nil not found in Orderred Collection" > - Proceed don't remove the c from the list and make arrives a nil, like > in the result deplaceReplaceC.png > - Abandon seems work well, but the next refreshing of the list (by > another move) make the nil appear too > > > 2) > Reproduce: > Deplace the 3 in the list of char, try to replace the 3 in the list of > int (at its place) > Error " '3' not found in Orderred Collection" > - Proceed duplicate the 3 gives the result DuplicateNumber.png > - Abandon affect all number after the place, they "become" the previous > number (BadNumber.png).
