#collect:as:Dictionary

by Peter UhnÃ¡k

Hi, is this intentional behavior? #(a b c) collect: [ :each | each -> each first asciiValue ] as: Dictionary. "a Dictionary(1->#a->97 2->#b->98 3->#c->99 )" (#(a b c) collect: [ :each | each -> each first asciiValue ]) asDictionary. "a Dictionary(#a->97 #b->98 #c->99 )" I would expect that collect:as: for Dictionaries would act in the same way as #asDictionary. {eter

Re: [Pharo-users] Feedback on #assert: vs. #assert:equals:

by Alexandre Bergel

Dear Nahuel, I think you are raising in excellent point. I think that assert: should raise an assertion error when a non-boolean is provided. I have added an entry: https://pharo.fogbugz.com/f/cases/16847/assert-should-not-raise-an-error-wi… Tomorrow we have a sprint, this is like an easy thing to fix. We will work on it!

It is like saying #assert:equals: is the "primitive" assertion message, which makes sense to me since you are always comparing if an object is equal to another, there's no reason to handle the booleans' case differently. > > What do you think? > > Thank you! > > Nahuel >

Fwd: FOSDEM 2016 devroom selection

by stephan

-------- Forwarded Message -------- Subject: FOSDEM 2016 devroom selection Date: Thu, 22 Oct 2015 13:18:25 +0200 From: Johan van Selst <johans(a)fosdem.org> To: devrooms(a)fosdem.org Hi, I'm sorry to inform you that we declined your devroom proposal. To clarify, your request was perfectly valid, but we had to choose. Unfortunately we do not have a sufficient number of rooms at our disposal to cover all requests. This year, we had over 60 requests for a devroom and were only able to accept 37 of those. However, some requests have been combined into a single devroom. Nevertheless, there are other ways to participate in FOSDEM too. You can still: - have a stand at FOSDEM, - hold a 15 minute 'lightning talk' in one of the biggest rooms, - speak in one of the other devrooms (CfP to follow), - hold a session in the community meeting room (new; CfP to follow). The full list of accepted devrooms will be published on the FOSDEM website later this week. On behalf of the FOSDEM devroom team, Johan van Selst
