Re: [Pharo-users] Week number from a date

by CÃ©drick BÃ©ler

Yes I agree. We may have a preference to set the week day start ( fistDayOfWeek ?) . After that we could agree on the fact the first week is the first complete week (otherwise it can be a preference). Then we need to find the first day index of the first fistDayOfWeek. (Date year: self year day: 1) weekdayIndex -> gives the index according to the preference (for now Sunday -> 1) Then itâs quite straightforward to get the week number. Just have to check if the current date is in the last week of the previous year (returns 52 or 53). I did something but not sure yet (but no preference). There are been some works on time representation (Chronos if I remember well ? but cannot load in Pharo 5, depends on OSProcess). An interesting read [1]. Cheers, CÃ©drik ps: http://stephane.ducasse.free.fr/Teaching/CoursAnnecy/0506-M1-COO/A%20New%20… Interesting to know. But I see this already seems hard coded... Date nameOfDay: 1 "--> #Sunday" Timespan subclass: #Date poolDictionaries: 'ChronologyConstants' ChronologyConstants class >> initialize DayNames := #(Sunday Monday Tuesday Wednesday Thursday Friday Saturday). Also seems to have changed at some point, with the historical nameOfDay recorded in the Terse Guide [1] circa 2010 shown to be different. Perhaps this is something we should make a regional preference. Was there any ongoing works on other regional preferences?

Re: [Pharo-users] Downloading large files with a progress bar

by Sven Van Caekenberghe

When the UI thread is really busy, updating the UI can be problematic. An extra fork seems to help: (FileLocator temp / 'PharoV30.sources') ensureDelete. [ [ :bar | bar title: 'Downloading Sources...'. [ ZnClient new url: 'http://files.pharo.org/sources/PharoV30.sources'; signalProgress: true; downloadTo: FileLocator temp ] on: HTTPProgress do: [ :progress | progress isEmpty ifFalse: [ bar current: progress percentage ]. progress resume ] ] asJob run ] fork. > On 13 May 2016, at 01:00, Offray Vladimir Luna CÃ¡rdenas <offray.luna(a)mutabit.com> wrote: > > Hi Sven, > > Thanks for your quick answer.
