Hello,
I do not see how to do a formatted print from a duration.
I would like to be able to do something like:
String streamContents: [ :s | 90 minutes formatted: âhh:mmâ printOn: s ]
The Duration>>#printOn: method prints the ANSI 5.8.2.16 format: [-]D:HH:MM:SS[.S]
The Duration>>#printHumanReadableOn: is not printing in the format I want.
Am I missing something or such feature does not exist actually?
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
