Re: [Pharo-users] Spec Drag n Drop and broken ListModel family
by Peter UhnÃ¡k June 10, 2016

June 10, 2016

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).

spotter usage - a rough analysis of categories
by Tudor Girba June 9, 2016

June 9, 2016

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. Cheers, Doru -- www.tudorgirba.com www.feenk.com "Value is always contextual."

Spec Drag n Drop
by Marion Noirbent June 9, 2016

June 9, 2016

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). Try to move the 4 make an error because it don't found 3, try to move the 5 make move the 4. 3) Reproduce: Deplace all items the list of int in the other Try to move the 'a' in the empty list of int Error "SubscriptOutOfBounds: 0" - Proceed remove the a from the list, but don't make it appear - Abandon seems work well

How much abuse can Teapot take?
by sergio ruiz June 9, 2016

June 9, 2016

I am currently planning a mobile (iOS) app that will rely on a REST server for handling offline tasks (sending emails, processing reports, etc). I would LOVE to use Pharo/Teapot for this, but I want to make sure that this configuration would be up to the task. I canât really guess how much traffic it will be getting, so i supposed the question i am asking is: is there a number of requests per second limit that this configuration can handle?

I have a feeling this is wrong, but I am not sure how to make it work cleanly.. This: |s| s := (((PipeableOSProcess command: '/usr/local/bin/mpc status') output) findTokens: Character lf) first should i have all the parenthesis in there? is there a cleaner way to do this? thanks! ---- peace, sergio photographer, journalist, visionary #BitMessage BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

GUI Applications
by sergio ruiz June 8, 2016

June 8, 2016

It would seem to me that in order for an ecosystem to really take hold on the part of the users, itâs really important that itâs efficient and easy to create a GUI based application. Can anyone comment on the current state of libraries for creating and distributing GUI applications? Thanks! ---- peace, sergio photographer, journalist, visionary #BitMessage BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

by Thibault ARLOING June 8, 2016

June 8, 2016

Hi, I reworked the Enterprise Pharo book as ePub taking into account feedbacks of the pass on first version. So, now the navigation menu is more developed and I added a cover for the book. It would be great to have new feedbacks on this version If some of you have electronic readers, it would be good to test the book on it too You can download the ePub here<http://files.pharo.org/books-ressources/entreprise-pharo/EnterprisePharo.ep…><http://files.pharo.org/books-ressources/entreprise-pharo/EnterprisePharo.ep…> Thanks, Thibault

[ANN] Glorp-SQLite3 for Pharo 5
by Pierce Ng June 7, 2016

June 7, 2016

Hi all, I'm pleased to announce the release of Glorp-SQLite3 for Pharo 5. Written and tested on 64-bit Linux Mint 17. You'll need to place the 32-bit libsqlite3.so where your Pharo 5 VM can find it. Take a fresh Pharo 5 image. Run the following: Gofer it smalltalkhubUser: 'TorstenBergmann' project: 'UDBC'; configuration; load. (Smalltalk at: #ConfigurationOfUDBC) loadBleedingEdge. Gofer it smalltalkhubUser: 'DBXTalk' project: 'Garage'; configurationOf: 'GarageGlorp'; load. #ConfigurationOfGarageGlorp asClass project stableVersion load. Gofer it smalltalkhubUser: 'DBXTalk' project: 'Glorp'; package: 'Glorp-SQLite3'; load. GlorpSQLite3CIConfiguration new configureSqlite3. GlorpDemoTablePopulatorResource invalidateSetup. Then run the Glorp tests in TestRunner. You should get 889 passing tests, with 12 tests skipped. The database file is sodbxtestu.db in your image directory. Feedback welcome. Pierce

June 7, 2016

Hi, I saw a post with the title "Spur Cog vs VW". Has anyone done this yet? Is there some code available somewhere that I could run? I have been searching on Google, but I haven't found much. A pointer in the right direction would be much appreciated. I'm really curious ;-) Thanks, -G
