displayingProgress on demand

by HernÃ¡n Morales Durand

Hello everyone, Is there a reason why #collect:displayingProgress: was removed or never included? And as more general question, is there any pointer to automatically add progress bar to iterator messages? For example doing: SmalltalkImage setDisplayProgressTo: MyClass. SmalltalkImage setDisplayProgressTo: MyPackage. and then having all enumeration messages sent in MyClass or MyPackage with a progress bar collect: collect:as: collect:into: collect:thenDo: select: select:as: select:thenDo: select:thenCollect:as: ...

Well written, Todd. I agree, the loss of indexing might not be that big a problem in practice. The only way to find out it to try an experiment I guess.

Well, I read the page/document/site as well. It was very interesting indeed, thanks for sharing it. In some sense it made me reconsider my aversion against in-image utf-8 encoding, maybe it could have some value. Absolute storage is more efficient, some processing might also be more efficient, i/o conversions to/from utf-8 become a no-op. What I found nice is the suggestion that most structured parsing (XML, JSON, CSV, STON, ...) could actually ignore the encoding for a large part and just assume its ASCII, which would/could be nice for performance. Also the fact that a lot of strings are (or should be) treated as opaque makes a lot of sense. What I did not like is that much of argumentation is based on issue in the Windows world, take all that away and the document shrinks in half. I would have liked a bit more fundamental CS arguments. Canonicalisation and sorting issues are hardly discussed. In one place, the fact that a lot of special characters can have multiple representations is a big argument, while it is not mentioned how just treating things like a byte sequence would solve this (it doesn't AFAIU). Like how do you search for $e or $Ã© if you know that it is possible to represent $Ã© as just $Ã© and as $e + $Â´ ?

(Resent because of bounce notification (email handling in osx is really beginning to annoy me). Sorry if its a dup) I used to worry a lot about strings being indexable. And then I eventually let go of that and realized that it isn't a particularly important property for them to have. I think you will find that UTF8 is generally the most convenient for a lot of things but its a bit like light in that you treat it alternately as a wave or particle depending on what you are trying to do. So goes strings - they can be treated alternately as streams or byte arrays (not character arrays - stop thinking in characters). In practice, this tends to not be a problem since a lot of the times when you want to replace a character or pick out the nth one you are doing something very computerish and the characters you are working with are the single byte (ASCII legacy) variety.

model vs interactionModel in rubric

by Andrei Chis

Hi, RubScrolledTextModel fails sometimes if the model does not have an interaction model set. For example in a few places there is a check that verifies if the model understands a message and then the message is send to the interaction model. evaluate: aStream andDo: aBlock .... (self model respondsTo: #doItReceiver) "check on the model" ifTrue: [ rcvr := self model doItReceiver. ctxt := self model doItContext] And then doItReceiver is implemented like: doItReceiver ^ interactionModel ifNotNil: [ :im | im doItReceiver ] "message send to the interaction model" Also in some cases a condition is checked on the model and then the actual result is obtained from the interaction model: (self model systemNavigation allImplementorsOf: aSelector) isEmpty ifTrue: [ self internalCallToBrowse: aSelector ] ifFalse: [ self model interactionModel systemNavigation browseAllImplementorsOf: aSelector ] I'll say these are bugs. Also should a RubScrolledTextModel always have an interaction model? Cheers, Andrei

The ia32-libs package was a hack to get 32-bit packages installed on a 64-bit installation. Since Ubuntu version 11.10 (Oneiric), Multi Arch has been added. One of the objectives for it is removing the ia32-libs package.
