Well its fortunate the our language works in dog years, so is that 10/7 ;) Seriously - I think you've shown that with a good engine (which I'm hoping it is - it seemed that way when I first came across a few bits in Dolphin) - and a bit of knowledge (although you have tons - but I'm hoping we can follow in your footsteps), a few people could make a big impact on what is possible (I certainly don't find it easy to even contemplate writing these things in Eclipse, as the model is very complicated). > > Have a look the method #refactoring in ORCmdCreateSubclassRefactoring > and ORCmdCreateSuperclassRefactoring.

Re: [Pharo-project] How do you extract a superclass if you can't select multiple classes?

by Tim Mackinnon

Well I'm certainly glad that you cared to get the tests back up to scratch - and it makes our whole community more productive. A big thanks for this! I'm just a bit embarrassed that in our community - we keep talking about how we have these great refactoring tools (that were invented in smalltalk) - but it looks like in Pharo (and I guess Squeak) - they've fallen a bit behind in terms of usability. My scenario is a very frequent one - and it should be possible to do effortlessly (and I think that the pieces are in place to do it). Maybe at ESUG we can rally some energy to help support some of these things (hold an appeal fund... not money - but contributions). I want to help - I just am not sure how to yet - and sometimes this is partly my surprise to discover that some of the things I thought already worked - don't. Maybe in the show us your projects demo's it might be worth replaying this scenario and showing how it works in Pharo, and how it works in Eclipse (and maybe another Smalltalk) - and then showing some of the features available in the refactoring engine and trying to get support for improving it. This along with useful keyboard shortcuts are the things that eat away at the awesome productiveness I've noticed in other areas.

Rather randomly. ;) If you merely need to export a package so you can import in gemstone, you could change: MCMczWriter >> addString: internalString at: path | member utfConverter utfStringStream| utfConverter := TextConverter newForEncoding: 'utf8'. "(Or whatever other format Gemstone thinks .mcz definitions will be)" utfStringStream := RWBinaryOrTextStream on: String new. utfStringStream binary. utfConverter class writeBOMOn: utfStringStream. utfStringStream ascii. utfConverter nextPutAll: internalString toStream: utfStringStream. member := zip addString: utfStringStream contents asString as: path. member desiredCompressionMethod: ZipArchive compressionDeflated (Alternatively use String new writeStream if you don't need/want to write BOM). Doing changes like this in the base image is unlikely without further investigation, as it would probably break reading new packages (saved in proper utf8) containing WideStrings into old images. I haven't read the import code, but if the binary format is preferred by old images if available, it might be a reasonable compromise saving the source in utf8, provided you also include the binary file. Cheers, Henry PS. Another fun fact I encountered when porting Assets: Monticello uses MethodReference>>source, which kindly converts all LF / CRLFs in your source / strings in the source to CR. So you can forget f.ex. trying to save arbitrary ByteArrays as strings in your code, and expect them to work the same when converting back to ByteArray after saving to monticello :)

Re: [Pharo-project] How do you extract a superclass if you can't select multiple classes?

by Max Leske

I agree. From a desing perspective, it's totally contra intutitive that multiple selection isn't possible in the browser. And (at least when comming from other systems) it is even more confusing to have the refactoring browser show an item "selection..." when you weren't able to select more than one item. I'm not implying that the browser doesn't supply a way to perform the refactorings, only as Tim's and my problems show, I see a problem in the design, an unnessecary one even. But since I don't know what the plans are for OmniBrowser... Maybe there's already a replacement or update coming along?

Re: [Pharo-project] How do you extract a superclass if you can't select multiple classes?

by Tim Mackinnon

Hmmm - (again if you can please be patient with me)... I really am missing something big here? So in my example class X and Y are subclasses of WAComponent - which has tons of subclasses (it could be even worse, they could subclass Object?). So does this mean that I should create my superclass A first? E.g. I create a new subclass of WAComponent, called A. I then make X and Y subclass A. Now I can do the "Refactor Class | Create Subclass" refactoring, and so I have to call it A2 (ultimately I only want A - but if needs must). Then I do get the prompt that you are referring to and can select both X and Y. Finally it just offers to make me class A2 but unlike what I was trying below it doesn't offer to move up any methods or instance variables???? So this doesn't work? And furthermore it seem much more convoluted than it should be? I don't understand why Refactor Class | Create Superclass doesn't prompt me for other peer classes (this is what I want - in fact what I really, really want is to select 2 classes in the first place). Maybe I'm being really stupid, or does no-one use this refactoring in Pharo? It would seem that my scenario is a very common one - so I'm struggling with this. And frustratingly it seems that all the horsepower to do this, is built into the tools but they just don't use them in an intuitive way?

Re: [Pharo-project] How do you extract a superclass if you can't select multiple classes?

by Lukas Renggli

Select the superclass of your classes X and Y and perform the 'create subclass' refactoring. A dialog asks you to choose the subclasses of your new class. This old website describes most of the refactorings: http://st-www.cs.illinois.edu/users/brant/Refactory/Refactorings.html. There is also a description in the tooltips of the menu actions.
