[Pharo-project] PBE correction: #xor: -> #bitXor:

by Nick Ager

Hi, Apologies if this isn't the best place to post corrections for the Pharo book. I'm using the latest PBE I can find (PBE1-2010-02-01.pdf). On page 200 I think all references to #xor: should be replaced by #bitXor: as my pharo-1.0 image doesn't contain #xor: except on False>>xor: and True>>xor: So Book>>hash should read: Book>>hash ^ title hash bitXor: authors hash Thanks for a great resource, Nick

Ah! Now, I get it. What about this?

Re: [Pharo-project] how to simply double a ' inside string

by Peter Hugosson-Miller

Oscar, you should think of the question as: "what is the simplest piece of code that could take your string ('''''', which has two quotes in it) and return a new one with four quotes in it instead of two?" -- Cheers, Peter On Tue, May 4, 2010 at 10:33 AM, Oscar Nierstrasz <oscar(a)iam.unibe.ch>wrote: > > s := ''''''. > s size -> 2 > > works fine for me. am i missing something? > > - on > > > > On May 3, 2010, at 22:54 , Schwab,Wilhelm K wrote: > > > Stef, > > > > First, try #printString - it might do the job for you.

[Pharo-project] Pharocasts: Dynamic finder with #doesNotUnderstand, #perform and Regex

by laurent laffont

Here: http://pharocasts.blogspot.com/2010/05/dynamic-finder-with-doesnotunderstan… This is the sequel to SandstoneDb, simple ActiveRecord style persistence screencast. I show how to: - override Object#doesNotUnderstand in your class to answer to unknown messages - use regular expressions to extract substrings - use #perform: and #perform:with: to send a message dynamically - develop new code in the debugger without stopping current call. Inspired by Ruby On Rails ActiveRecord dynamic finder. Cheers, Laurent Laffont

Re: [Pharo-project] Set + collect:

True.It can be impractical, but no need to change #collect: Please use #detectSum: (Set with: 'one'->1 with: 'two'->2 with: 'dos'->2) detectSum: [:e |e value]. or #collect:as: ((Set with: 'one'->1 with: 'two'->2 with: 'dos'->2) collect: [:e |e value] as: Array) sum.
