Re: [Esug-list] Pharo Consortium Important Documents and Request for Feedback

by Yuriy Mironenko

You will probably want to add something special for self-employed - like me. Let me explain. I'm self-employed and I making pharo-based solutions. So my interest in pharo is somewhat stronger than just "hey, it's cool and I just like smalltalk". At the same time I'm not (hopefully yet) reached the size of "small firm". I can't afford 2000 euro/year - it's my income for several months (3 to 5 depend on my luck). But I definetely can afford more than 40 euro/year. I have a feeling that my case is not unique, especially in Argentina. You see, smalltalk is not mainstream, and neither Pharo. So it's natural to start as an self-employed. And it takes considerably big time to reach "small firm" size. Maybe some argentinians (or russians, or anybody else) can confirm (or decline) this? Of course, it is possible to make donations without be involved into Consortium. But it's much...mmm...pleasant to be "involved". I expect that more (and more regularly) funds will be collected if invite self-employed to join the consortium rather than just propose to make donations. P.S.

Re: [Esug-list] metaprogramming in smalltalk

by Guillermo Polito

Hi Vitaly! try to think it like this: #perform:with: is a reflective operation to send messags to an object. Thus, if you are trying to send an object a message like: object perform: someSelector with: someArgument. - The receiver is object - the selector of the message is #perform:with: - the arguments of #perform:with: are someSelector and someArgument. Then, what you have to do is object perform: #perform:with: withArguments: { someSelector . someArgument } Because #perform: and #with: are not two different messages, they are two keywords of the same selector, in the same message. Then, you have to treat them together. Cheers, Guille 2012/4/29 Vitaly Kosenko <vitaly.kosenko(a)gmail.com> > Nice!
