[Pharo-project] how can I get bit representation of numbers

by StÃ©phane Ducasse

Hi guys I thought that printStringBase: 2 would do the trick but it only works for positive number. I would like to see the two complement representation of numbers. So I implemented something like that but I wonder if this is correct. | v | v := 10. String streamContents: [:s | 31 to: 1 by: -1 do: [:i | s nextPut: ((v bitAt: i) + 48) asCharacter ] . s contents] Integer readFrom: '0000000000000000000000000001010' base: 2 | v | v := -3. "1111111111101" String streamContents: [:s | 31 to: 1 by: -1 do: [:i | s nextPut: ((v bitAt: i) + 48) asCharacter ] . s contents ] '1111111111111111111111111111101' Now Integer readFrom: '11111111111111111111111111111101' base: 2 does not hold back -3 Stef

[Pharo-project] UTF converter fails to read tildes and Ã±

by Guillermo Polito

I've written the following test, which is failing. testReadÃ±Character | converter | converter := UTF8TextConverter new. self assert: 'Ã±' equals: (converter nextFromStream: 'Ã±' readStream). I attach a changeset with that test. Am I ok or UTF8TextConverter is behaving wrong? Thanks, Guille

[Pharo-project] TowardsFirst Class Tasks

by Gary Chambers

Sorry, unable to reply to original posts (554 Transaction failed : Cannot send message due to possible abuse). Curious as to what might be wanted from "Morphic 2"... Ideally with a non-temporal layout scheme ;-) Otherwise, tricky to have a framework that is end-platform agnostic, lowest-common-denominator issues etc. (google it) As for "task groups" + 100 Regards, Gary

Re: [Pharo-project] TWM and shortcuts

by Gary Chambers

I did some stuff with SVG in Squeak based around the Balloon engine. Too slow, better off with getting Rome/Cairo softed in Pharo!

You can try it load the latest version and evaluate: oxygen := ExternalIconFamily named:'Oxygen' . oxygen openNamedIcons . Regarding the future integration, i still don't know how to handle the imported icon data. Once an icon family has been imported (of course only a subset of the whole family can be filtered using the importer), the size is quit big to version in monticello, as a package. Yes. For some icons of TWMBar I just use Morphic to build them. Look for example at TWMBar>>bottomIcon and TMWBar>>iconSubmorphBounds: As icons are generally built from vectorial image, they usually can be exported in SVG. I wonder if a SVG to Morphic importer exists. Would be nice because we could have scalable icons without the size problem. pd: Remember you can also try oxygen := ExternalIconFamily named:'Oxygen' . oxygen openAllIcons . I've tried it but I could not see all icons. I've tried to use GeneralScrollPane in my script but I did not manage to make it work well. Laurent.

Ahh, I messed up the issue description. It is the current selection that is not announced, not the contents. Or is there a possibility to get the a notification of the current selection while I am selecting a piece of text?
