speed up with:do: by not checking size
by Marcus Denker Sept. 4, 2014

Sept. 4, 2014

with:do: on SequencableCollection checks that both collections have the same size (it raises an Error if not). with: otherCollection do: twoArgBlock "Evaluate twoArgBlock with corresponding elements from this collection and otherCollection." otherCollection size = self size ifFalse: [self error: 'otherCollection must be the same size']. 1 to: self size do: [:index | twoArgBlock value: (self at: index) value: (otherCollection at: index)] I think we should not do that: 1) it is slow 2) when the other is larger, is would work and just omit the rest 3) if it is smaller, you will get an error anyway There are just three methods doing such a size check: with:do: with:collect: reverseWith:do: (the last one actually raises a SizeMismatch exception, it is the sole user of that exception) Is there a reason why this makes sense? I added an issue with a slice to clean it up: https://pharo.fogbugz.com/f/cases/13946/speed-up-with-do-by-not-checking-si… Marcus

Undeclared dictionary
by Yuriy Tymchuk Sept. 3, 2014

Sept. 3, 2014

Hi, can someone explain me how Undeclared dictionary works? Because as I look at it, all the values are nil. Is it possible for them to be not nil? Maybe we should have a âglobal variable commentsâ for this situations :) Uko

Proportional Tab Stops
by J.F. Rick Sept. 3, 2014

Sept. 3, 2014

Hi everyone, I'm writing for two reasons. First, I wanted to let people know that I haven't disappeared. I'm just having to take a break as I finish up with my current academic post. As I am no longer going to be there, Pharo contributions don't help the department. So, I can't justify devoting any time to Pharo. But, I'm still interested in Athens, multitouch support, and Pharo for beginners. In October, I move back to Atlanta and will start a company. At that point, I aim to be back, though I may concentrate a bit more on server technology (full version of newest QRCode specifications half way done). Second, I wanted to mention a slight annoyance and suggest a solution. Background: I taught a class on introduction / intermediate programming in Pharo the last few years. One thing I try to teach my students is to use proper indention for their code. Unlike Python (great syntax for a first language), you do not need to indent in Smalltalk for code to work properly so students don't have to properly use indention to organize their code. For tiny bits of code (as is required in introductory programming), indention is not that important but it gets more important as they advance. Even my better students often used bad indention practices, though I emphasized it in class and all sample code I gave them was properly indented. In class, I often solved problems and demonstrated code. So that students could see what I typed, I increased the size of the font (24pt standard font). Though the font increased, the tab spacing remained the same. So, when I indented with one tab, it looked much smaller than a tab would have looked on their 10pt code editor. I saw people using spaces to indent code, which I never talked about. My guess is that they were trying to replicate the amount of space that my code was indented. They saw that a tab looked too big and used spaces. A simple solution is for tab spacing in code panes to increase proportionally with the font size. I feel like suggesting that as an improvement for Pharo 4. Does that seem reasonable? Are there arguments against it?

nil pointersTo size
by Ben Coman Sept. 3, 2014

Sept. 3, 2014

I am curious... what does it mean that nil PointersTo size is a large number? Intuitively I'd have thought the answer would be zero. Pharo build 40196 --> ~101,000 Pharo build 30856 --> ~103,000 Pharo build 20628 --> ~80,000 Squeak 4.5 --> ~40,000 cheers -ben
