What do you think? Yes, this is a bug. (the whole MethodReference stuff is right now in the process of being re-designed...) One workound is to get the real method and ask it for the code: (self systemNavigation allImplementorsOf: #browse) anyOne compiledMethod getSource. arcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe.

Can you give me a bit more about the kind of errors and failures you see. Does it look like stuff is completely missing ? Maybe I messed up the publishing after the various class moves that I did recently. No, fresh load into one-click 1.1.1 works for me. I guess I need to try different versions.

Status: Accepted Owner: stephane.ducasse Labels: Milestone-1.3 New issue 3533 by stephane.ducasse: add Dictionary>>at:ifAbsentPutValue: http://code.google.com/p/pharo/issues/detail?id=3533 Igor suggests to add this method in dictionary to avoid to use block closure when not necessary. Here the block has to be passed and executed. When you know the value you want to put this is extra work. at: key ifAbsentPut: aBlock "Return the value at the given key. If key is not included in the receiver store the result of evaluating aBlock as new value." ^ self at: key ifAbsent: [self at: key put: aBlock value]

Can't just load the CoreTests and have all tests pass though, due to the isAbstract implementation in XTReadingWritingTest. Maybe XTReadingWritingTest, XTInfiniteReadingWritingTests and XTFiniteReadingWritingTests should be moved to the Terminals-Tests package? Cheers, Henry

[Pharo-project] How to bundle an application with icons?

by Dimitry Golubovsky

Hi, Suppose I need to bundle a Pharo application (a package) I am developing with some custom icons: is there any "standard"/ agreed-upon method to do that in Pharo? For example the MenuIcons class includes byte strings (automatically I assume) converted from some external PNG files that show up as icons with menu items: which tool can be used to create a class with set of icons for an arbitrary application? If I want to reuse icons for standard actions in my application, which is the proper way to access menu icons other than to directly access these stored images? Thanks. PS Other than the "by example" books (both Squeak and Pharo) which give some basics of building GUI for applications, are there any general guidelines for GUI building in these systems? -- Dimitry Golubovsky Anywhere on the Web

(which I doubt since the loading script uses > Gofer instead of Installer and Gofer is Pharo while Installer is > Squeak). I'm currently using Pharo OneClick image version 1.1.1 directly from the download page. Currently I'm running using the old VM as Cog once crashed on me and I lost a lot of changes. But both VMs seem to run the tests OK. > Would be nice if we could have a working ConfigurationOfXtream in http://squeaksource.com/MetacelloRepository so it is easy accessible and working packages are versioned together using Metacello. Yes, I probably need to do that as well. So far I was a bit discouraged mostly by my ignorance. I'm not up to speed on metacello yet, there don't seem to be any tools pre-loaded in the one click image, and I don't know what should one load to get some. I was able to figure out how to use ConfigurationOfFFI but in the end I ended up running the class side load method by hand. The other issue I had was that it seems a metacello configuration requires a bit of maintenance, it seems like you have to manually update the versions when you publish something new. That may be less of a problem now after the updates are done. The Gofer expression seemed a lot easier, and I hoped sufficient for now. Anyway, unless someone beats me to it I'll see what I can do about creating a configuration. Martin

[Pharo-project] senders vs implementors

by Tudor Girba

Hi, I think I encountered an error in allImplementorsOf:, but I am not quite sure and I wanted to run it by you first. If you evaluate (self systemNavigation allSendersOf: #browse) anyOne sourceCode. you get the source as expected. However, if you evaluate: (self systemNavigation allImplementorsOf: #browse) anyOne sourceCode. you get an error. The last snippet used to work just fine in Pharo 1.1.1. I consider it a bug. What do you think? Cheers, Doru -- www.tudorgirba.com "Sometimes the best solution is not the best solution."
