How to load a baseline in Iceberg? Get #addTo: sent to nil?
by Tim Mackinnon Aug. 3, 2017

Aug. 3, 2017

Iâm wondering if Iâm missing a trick somewhere - but I have a simple project with 2 packages, one is a BaseLineOfMyPkg and the other is MyPkg (technically I donât need the BaseLineOf, but I was learning how to use them and I simply added a postLoad hook to run some code in it). Anyway, If I clone my repo with Iceberg, I get 2 unloaded packages in the UI. If I right click on the BaseLine one, and click the âinstall baseline (default)â option, I was expecting it to load both packages for me - however I get the talkback error â#addTo: was sent to nil from the MCRepositoryGroup>>addRepository: methodâ. In trying to debug the code I can see its trying to find a handler for gitlocal:/// <gitlocal:///>, doesnât find one and then tries to create a repo and bailsâ¦ this seems like a bug? I did notice in tracing the code that there is a reference to a Setting that I saw - âEnable Metacello Integrationâ - should I set that to true (its false by default)? Iâm wondering how other people are loading their projects in Iceberg if this doesnât work? Tim

Unknown variable warning with a method name when saving a method
by Myroslava Romaniuk Aug. 3, 2017

Aug. 3, 2017

Hi, I'm trying to add the rewrite option to the Match Tool, and when I create a method and try to debug the code I get the following: So basically it tells me that the name of the method is an unknown variable which I don't get at all. And when I try to set it as a temporary variable just to see what I'll get, I actually get an error like this...Anyone has any idea what can be the problem? Thanks, Myroslava

hard reset class variable state
by Ben Coman Aug. 3, 2017

Aug. 3, 2017

I want to reset all the class variables in an application to nil. I've got as far as finding them, for example... packages := RPackageOrganizer default packages select:[:p| (p name includesSubstring: 'PharoLauncher') ]. stateToReset := packages flatCollect: [:p| p definedClasses select:[:c | (c classVarNames size > 0) and: [(c name includesSubstring: 'Configuration') not]] thenCollect:[:c| c-> c classVarNames] ]. stateToReset asDictionary keysAndValuesDo:[:class :variables| variables do: [:v| Transcript crShow: 'Clear ', class printString, ' -> ' , v printString]. ]. What could go in place of the Transcript line to set them to nil? cheers -ben

What sets the Monticello Local Cache Directory default in a new image?
by Tim Mackinnon Aug. 3, 2017

Aug. 3, 2017

Hi - Iâve noticed that when I download a new image+vm with zeroconf (in a fresh directory) - that when I launch it, the setting Tools | Software Config Mgnmnt | Monticello | Local Cache Directory has a value that points to a directory from one of my earlier images. Is this normal (does it store this information somewhere on my computer so that different setups can access it)? At first I thought this was annoying - but Iâm now wondering if this is useful as Iâm guessing that there isnât any reason to have separate caches for version controlled libraries and so maybe I should actually set it to some common directory? What is the recommended strategy? Tim

GT Playground, pages dropdown menu - how does it work?
by Tim Mackinnon Aug. 3, 2017

Aug. 3, 2017

Hi - overtime I think I understand how the pages dropdown for the playground works, it then doesnât do what I expect? I have learned that double clicking a page tab will put the page into the stash directory with a name (which is cool), but then it doesnât always seem to appear in the dropdown list - however I have learned that Spotter will find these pages if I use #playgâ¦ So if spotter can find them, why does the playground dropdown seem to temperamental, or am I missing some obvious trick for clearing a cache or something like that? Or maybe its a bug? It would be nice if it would work, as its very handy as quick way to swap to a script. Tim

ConfigurationOfZincHTTPComponents in Pharo 7
by Alistair Grant Aug. 2, 2017

Aug. 2, 2017

Hi Everyone, Pharo 6 included ConfigurationOfZincHTTPComponents as part of the core image, but it is no longer included in Pharo 7. Can someone tell me where to load ConfigurationOfZincHTTPComponents from, or what its replacement is? In particular, I would like to load the WebSockets code. Thanks very much, Alistair
