Glorp / SQLite3 issue
by Alistair Grant June 11, 2016

June 11, 2016

Hi All, I'm working my way through some of the examples in PharoInProgress/Glorp. Adapting Pierce's code from his announcement: | workingDir dbName login session | workingDir := SmalltalkImage current imagePath asFileReference parent fullName , FileSystem disk delimiter asString. dbName := 'glorpbook.db'. login := Login new database: UDBCSQLite3Platform new; host: workingDir; port: ''; username: ''; password: ''; databaseName: dbName; yourself. PharoDatabaseAccessor DefaultDriver: GlorpSQLite3Driver. session := GlorpBookDescriptorSystem sessionForLogin: login. session createTables. However this fails with: MessageNotUnderstood: receiver of "basicExecuteSQLString:" is nil If I add a breakpoint in GlorpSession>>accessor: manually execute: accessor login and then proceed, everything works fine. Given that Glorp has been around for so long, I guess that this is more likely an issue with the new UDBC driver, however I don't yet understand the architecture well enough to propose a fix. Any suggestions? Thanks! Alistair

synchronized return from asynchronous message block
by Peter Uhnak June 10, 2016

June 10, 2016

Hi, is it possible to return "synchronously" even if I have an asynchronous message? For example: SomeObject>>someMethod ^ UIManager default chooseFrom: #(a b c) When the above method is executed, it will open a popup and block the execution until I select something, then it will return the selection. But if I instead have something like this SomeObject>>otherMethod |choice| NewListModel new items: #(a b c); whenSelectedItemChanged: [ :item | choice := item ]; openDialogWithSpec. choice. Then it will open the window but it will immediately return nil. So my question is: is it possible to synchronously return even in the second example / block the flow until a selection is made? Thanks, Peter

OSProcess command - non responding image when calling often
by Sabine Manaa June 10, 2016

June 10, 2016

Hi, sorry but I have another issue with OSProcess. For my app, I want to show small .png previews from my .pdfs. For this reason, I use an external software, currently pdfbox. It works fine, but regularly, I get a hanging image. I tried to reproduce it and found out, that it is not a problem with pdfbox (http://pdfbox.apache.org) because from command line, I can call it often without problems. There can be (hopefully) many users in my app with many previews at one time. So I have to call it often. For reproduction of the OSProcess issue, I used another simple command (from my other OSProcess umlaut issue :-)) to test it. calling this, results in a non responding image: 20 timesRepeat: [OSProcess command: ('cp /Library/WebServer/Documents/reports/bar.pdf /Library/WebServer/Documents/reports/test-c.pdf').]. also this: 20 timesRepeat: [OSProcess command: ('echo "Hi there"').] My original code is similar to this but here only for information: OSProcess command: ('{1} -jar {2} PDFToImage -format PNG -page 1 -dpi 100 {3}' format: {'Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java'. '/Users/sabine/Desktop/pdfbox-app-2.0.1.jar'. '/Library/WebServer/Documents/reports/201411121510-112859865-3378921/20150605_170_IFA_Berlin_Reisekostenabrechnung.pdf'}). So, my question is: is it wrong, calling OSProcess like this? How to do it instead? I am sorry to ask again and hope that there is a simple solution. Or is it a bug in OSProcess?

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
