Messages that use construct like: [self atEnd] whileFalse: [...] should always work. Messages that use constructs like: [(char := stream next) ~~ nil] whileTrue: [...] could eventually be written: | oldEndOfStream | oldEndOfStream := endOfStream. [[(char := stream next) ~~ nil] whileTrue: [...]] ensure: [endOfStream := oldEndOfStream].

[Pharo-project] Why TTComposite is a subclass of TTGlyph

by StÃ©phane Ducasse

TTGlyph subclass: #TTCompositeGlyph instanceVariableNames: 'glyphs' classVariableNames: '' poolDictionaries: '' category: 'TrueType-Fonts' This class represents a composite TrueType glyph, e.g.one which contains many simple TTGlyphs. Does a TTCompositeGlyph needs all the state from its superclass? Alain I'm going over the super initialize cs now. TTGlyph>>initialize bounds := 0@0 corner: 0@0. contours := #(). advanceWidth := 0. leftSideBearing := 0. rightSideBearing := 0. but in the subclass TTCompositeGlyph>>contours ^contours ifNil:[contours := self computeContours] so if we change the initialize of the subclass then the countours will be never computed....

Re: [Pharo-project] what happened to pretty-print?

by Alain Plantec

StÃ©phane Ducasse a Ã©crit : > If I remember we removed the coloring which was broken. > > Alain did we remove the pretty printing too? > no, it works well on my core image: In a browser, choosing 'pretty print' in the "what to show" button makes the code pretty printed. Code is always pretty printed if you check 'BrowseWithPrettyPrinting' preference. With pharo, shout-coloring is working. Is it ok Oscar ? alain

Hi mike when we copy and paste from other environment we get a problem: we get a box instead of the correct CR. Do you know what should be done? Stef

If I remember we removed the coloring which was broken. Alain did we remove the pretty printing too? Oscar yes the copy and paste should handle correctly the carriage return.
