Re: [Pharo-users] Formatted print for Duration

I chosen something like the second solution to avoid adding a dependency to my project (it is a bit overkill for what I wanted to achieve). But shouldnât this formatted-print feature be added in Duration?

Not sure you can use it for that. I mean, you wanted random pairs of people no? So no need to rank people according to some preferences?

There were some real glitches in the newpipeline and now I'm ready to produce a booklet. Now I will check and fix some more... And yes I want to remove the dependencies to Magritte and Grease and get a modular core. But first I want to arrive to a stable point and migrate all the books and booklets to Pillar 70.

Hi steven If I understand what you mean, you cannot from Pillar. Pillar is agnotisc from a layout point of view. You can edit the sbabook cls.

Hi Julien I did not find a ready made method for that, either. Probably because there is no standard way to print a *Duration* as minutes and seconds, because it is not obvious how to print it (Compared to instances of the *Time* class). My solution would be to implement your own printing method using the GRPrinter from the Grease package (Installable through Catalog Browser in Pharo 6): ***************************** | hoursPrinter minutesPrinter printer | "Note: you can not use 'duration minutes', since this will give you only the partial minutes inside a day" hoursPrinter := GRMappedPrinter block: [ :duration | duration asMinutes // 60 ] next: (GRNumberPrinter new). minutesPrinter := GRMappedPrinter block: [ :duration | duration minutes ] next: (GRPrinter numberWithAtLeastDigits: 2). printer := hoursPrinter, $:, minutesPrinter. ^printer print: (9876 minutes) "Will result in '164:36'" ***************************** 2. solution: Or just dead simple: ***************************** | duration | duration := (9876 minutes). ^(duration asMinutes // 60) asString, ':', duration minutes asTwoCharacterString ***************************** Cheers, Andreas -- Andreas Brodbeck www.mindclue.ch
