A DateAndTime that does not understand #date or #time?

by Sebastian Sastre

How are we going to tell that our DateAndTime does not understand #date nor #time? (and keep our face straight) Sorry for the drama but hey... the raison d'Ãªtre, its meaning, the purpose in the life of a DateAndTime is to make you able to send messages about date and time :D How come that the most basic ones are being omitted? Am I missing something? sebastian o/

Indeed to me asString is a really a conversion method and we should not use it when we mean printString. this is why there is a difference between #foo asString -> âfooâ #foo printString -> â#fooâ now the problem with displayString is that it works only on few case: the case where you have a single nice textual representation. I think that in general the list or other should provide a hook to display the items nicely.

So, Kevin, I separeted the x-axs labels as you requested, you can try it, just do: | diagram | diagram := GETDiagramBuilder new. diagram verticalBarDiagram models: (-10 to: 10); color: [ :each | (each > 0) ifTrue: [ Color blue ] ifFalse: [ Color red ] ]; modelAxis.

Re: [Pharo-dev] stroke width in Athens

by Igor Stasenko

to make stroke width unaffected by scale, you obviously will need to scale it down by same factor as you scaled geometry i.e.: canvas pathTransform scaleBy: factor. strokePaint width: myWidth/factor.
