Re: [Pharo-project] Pharo sprint @ Brussels

by Johan Brichau

Hi everyone, I updated the Sprint section on the wiki (http://code.google.com/p/pharo/wiki/PharoSprints) with directions to the Brussels Sprint, summarized below: Place: Software Languages Lab, 10th floor of building F, Vrije Universiteit Brussel, Belgium Map: http://www.vub.ac.be/english/infoabout/campuses/etterbeek.html IMPORTANT: on Saturday, you can only enter the building via the north entrance between building E and F (near the letter 'R' on the map) and tell security that you are here for the Pharo Sprint. In case you have trouble finding it, please phone Andy: +32 494 42 32 56 or Johan: +32 476 78 64 45 If you are coming by car, you need a barcode to access the campus via entrance 6 or 13. Just print this pdf and use the barcode on it.

by Adrian Lienhard

Yes, I would welcome such an extension! I wouldn't invent a new syntax, though, but just use the existing protocol array copyFrom: 1 to: -2 Cheers, Adrian On Jun 7, 2010, at 13:47 , Niko Schwarz wrote: > Hi guys, > > Am I the only one who finds the ruby protocol for accessing > collections richer at times?

[Pharo-project] A more concise array access (using negative indices)

by Niko Schwarz

Hi guys, Am I the only one who finds the ruby protocol for accessing collections richer at times? In Smalltalk, if ary is an array, how do I get ary without its last element? In Ruby, it's dead easy: ary[0..-2]. I can do that by heart after not having done any serious Ruby in a long time. In Smalltalk, I have to search through a long list of method names, because there are just so many possible names for the method. The point is: would it be totally out of reach to try and get a more concise and unified way to access sequenceable collections? I know I'm sort of asking for the slaughter of a holy cow: Smalltalk only has telling and easy message names all over. Or wait, does it? There's of course Class >> #methodName. And 2 @ 3 for points. Just to put something on the table, how about: (ary at: 1, -2) Or, without braces, if you don't mind the reversal: 1,-2 @ ary Or, consistent with current naming conventions: (ary from: 1 to: -2) Just my 2 cents, what do you think?

Re: [Pharo-project] GAUCHO 1.0 released!

by Simon Denier

Hi Fernando Already lots of good stuff in your app. It looks *very* good and it feels quite good. I especially like the toolbar and the icons, as well as the shape toolbar which appears when overing over a shape (the "appear" effect is too long though). Is it possible to import/develop existing packages/classes into Gaucho? That would be a cool way to go beyond BankAccount for people who want to try it on larger scale :) On 7 juin 2010, at 00:22, Fernando olivero wrote: > Hi Pharo programmers! > > We are happy to announce that Gaucho 1.0 is released. > > Gaucho is a direct manipulation environment for software. > > If you want to try it out go to http://gaucho.inf.usi.ch/ . > > Gaucho1.0 works in Pharo1.0. > > In the releases section you'll find the installation script , and a description of all the features of Gaucho1.0. > > Any feedback you are willing to provide is welcomed! > In the website you will find a bug issue tracker and the mailing list description. > Or you can also send us an email for any other purpose, such as demo-request or inquiries about the Gaucho project. > > > Hope you enjoy using it as much as we do! > > Fernando Olivero > University Of Lugano > > > pd: Be ready for the next version, with many improvements and added features!
