It makes harder to extend your code. Because if method `a` calls method `b`, then even if method `b` is not defined in your class, I can subclass and redefine method b. Otherwise I have to subclass and redefine `a` although `a` is fine, but I want to run my `b` and not the one of superclass.

Seaside REST on Pharo 50

by Franck Warlouzet

Hi, We are currently using seaside, magritte, reef etc to do a project at school. We also have to do a mobile app (written in Java :(), so we are doing a REST service to access the database from the mobile app. We are working on Pharo 50, and we noticed that Seaside-REST is not working anymore. For simple get, it is ok, for example : test <get> ^ 'foo' but if you want to have a complete path like that : test: aValue <get> <path: '/foo?value={aValue}'> ^ 'foo' You get a DNU RBVariableNode>>key during the route creating (Same on pharo 40 is working). Any idea why ? In the meantime, we are using Teapot, it seems to be working on Pharo 50. Btw, I cannot subscribe to seaside mailing list (I never get the confirmation mail), so if someone could forward this email on seaside mailing list, it would be nice. Franck

It makes sense, maybe the class Date is not the best for those methods, but there isn't a "Calendar" like class either. Whatever is chosen, it should collaborate with the Locale, but be able to use any other locale to retrieve the names. Esteban A. Maringolo

Re: [Pharo-dev] Improving API of Date, Month....

by Skip Lentz

Hi, I also had an idea for a method which returns the most significant unit of a Duration. For example, you have a duration of 432 days, 3 hours, 21 minutes, 5 seconds, etc., and it would return you "432 days" (or just â1 yearâ). I encountered this when wanting to create a time indication on e.g. a commit or a comment. Itâs much more readable and user-friendly than a timestamp. Would this be a nice addition to the Duration API? > On Nov 24, 2015, at 3:59 PM, stepharo <stepharo(a)free.fr> wrote: > > Hi > > I was reading the code of Date and I was expecting to get some methods such as > monthNames > dayNames > daysInMonths > > Ok they are stored in ChronologyConstants but they are not accessible. > There is no monthNames nor > > Do I imply something strange or silly? > I think that it would make sense to add them. > > Stef >

Hi I was reading the code of Date and I was expecting to get some methods such as monthNames dayNames daysInMonths Ok they are stored in ChronologyConstants but they are not accessible. There is no monthNames nor Do I imply something strange or silly? I think that it would make sense to add them. Stef
