STON: Skip Inst Var
by Sean P. DeNigris Sept. 9, 2017

Sept. 9, 2017

I was migrating some data from Pharo 4 to Pharo 6.1 and fell over the fact that FileSystem has a #workingDirectory instVar in the source, but not in the target. I ended up monkey patching STON until the objects were loaded and then reverting, but is there a way to skip an inst var via the proper STON API? ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Pharo 6 FileSystem>>changeDirectory: is missing
by Andreas Sunardi Sept. 9, 2017

Sept. 9, 2017

I found FileSystem class has changed from Pharo 5 to Pharo 6. I've been using FileSystem>>changeDirectory to make my program (Pharo 5) runs in the current working directory (thus able to find local files). This is now broken because #changeDirectory doesn't exist anymore. The change seems intentional. Question: Is there a different way in Pharo 6 do set working directory or is this a bug? -- Andreas

Few days old 6.1 image now leaves window trails?
by Tim Mackinnon Sept. 8, 2017

Sept. 8, 2017

Hi there - Iâve been running in a 6.1 64bit image for a few days - doing a few experiments at lunch times, debugging things etc. I have had a few infinite loops that Iâve had to Cmd-. Out of and clean up lots of windows (whoever came up with the close all windows to right is a star!). Anyway, I just noticed that now when I drag windows around in the world - they leave lots of window trails around. Redrawing the screen cleans it up - but Iâm wondering what causes this? I tried running the the TimeProfiler and 91% of the time when dragging a window around is in BlockClosure>>newProcess but this doesnât seem out of what with another image that doesnât exhibit this behaviour? Is there something that I should do to clean up? I wondered if I might find some stuck process in the background that was gobbling cpu - but I donât really see that (but is there an easy way to check?). Tim

BlockStyler: Make Blocks more recognizable in source code
by Manuel Leuenberger Sept. 8, 2017

Sept. 8, 2017

Hi everyone, I built a little syntax highlighting extension for the Nautilus source code pane, which puts a background color behind blocks, so that nested blocks are easily recognizable. Install with: Metacello new baseline: 'BlockStyler'; repository: 'github://maenu/BlockStyler/repository'; load GitHub: https://github.com/maenu/BlockStyler <https://github.com/maenu/BlockStyler> Doesnât work with âFormat as you readâ, just as the IconStyler. If anybody has an idea how to integrate it properly into Nautilus as a plugin, let me know. Currently itâs an ugly meta-link hack to get access to the sourceTextModel. Cheers, Manuel

Glorp: problem with DictionaryMapping with "data objects"
by Herby VojÄÃk Sept. 7, 2017

Sept. 7, 2017

Hello! I have the problem with mapping dictionary of key to simple data-holding object (two integers) work. Glorp DictionaryMapping dicriminates between mapping a simple value (#dictionaryFrom: String to: Integer), where things work as assumed (having two fields in a table, one for key, one for value; and of course one for FK to owner) and mapping an object (#dictionaryFrom: String to: MyClass), where it fails miserably if the object does not contain the key itself as the FK as well (which is dumb; I want it unidirectional). In case I do not include the key-as-FK, it fails to grasp update and/or deletes, and fails during commit with either UNIQUE failure (when update is interpreted as insert) or with NULL failure (where delete is interpreted as insert with nil in place of dict key field). Maybe it is a missing feature in DictionaryMapping; maybe I am doing something wrong. I would like to ask if there isn't someone currently on ESUG who would want a bit of more sightseeing and would be willing to get a detour via Bratislava (I have a place for stayover) and look at the issue face to face (or I can use ScreenHero, but as I understood it does not have Linux client, maybe that's why Esteban did not accept my invitation yet). Thanks, Herby
