(between or:, and:, xor:. They are so close that it's strange to have different parameters for them. On the negative side, it does cost a send of #value (quick return self) for the case that one calls it on a boolean...

[Pharo-project] Howto measure memory footprints of functions/objects/libraries in Pharo?
by Guido Stepken Nov. 18, 2010

Nov. 18, 2010

E.g.: Three different solutions for a Euler problem: (1 to: 999) inject: 0 into: [:sum :i | (i \\ 3 = 0) | (i \\ 5 = 0) ifTrue: [sum + i] ifFalse: [sum]] (1 to: 999) detectSum: [:i | (i \\ 3 = 0) | (i \\ 5 = 0) ifTrue: [i] ifFalse: [0]] (1 to: 999) detectSum: [:i | i * (#(0 0 1 0 1 1 0 0 1 1 0 1 0 0 1) atWrap: i)] How do i measure the exact memory footprint of each solution? Pharo claims having reduced memory footprint at many places. Can that be proofed, e.g. with one comparable demo app, once run in old squeak, once in Pharo 1.1/1.2? And no, MessageTally spyOn: does not do right! Tnx in advance, Guido Stepken

Hi folks.. i found today, that xor: don't recieve a block and recibe aBoolean i can guess, it is wrong, because, the other logic operations recieve blocks like parameters.. I this a bug? Best Regards

No 'platformName' offered by Shout completion mode. shout or oCompletion because oCompletion is based on the frequency of the last message you typed and it does not register all the method of the services at first. > And: I cannot choose from other offers in suggestion list by clicking with mouse.

I suggest you to stay friendly if you want that we spend our time to reply nicely to you and I will not be as violent as you and I fully understand your frustration.
