Re: [Pharo-users] Polymorph example

by laurent laffont

The problem is that I've code it in Pharo 1.2 and use UITheme class>>smallWindowIcon to add the menu in ContactListEditor class>>menuCommandOn: But in Pharo 1.1 UITheme class>>smallWindowIcon doesn't exist (it's MenuIcon class>>smallWindowIcon). I've uploaded a new version on SqueakSource which don't use icons + some code refactoring.

Re: [Pharo-users] Screencast proposition: Watch someone read code.

by laurent laffont

Hi, indeed I don't really see how to do this sort of screencast ..... Which packages would you like to see explained ?

Hi, after evaluating: Gofer it squeaksource: 'LaurentLSandbox'; package: 'AddressBook'; load. (Smalltalk at:#ContactListEditor) open. in Pharo 1.1.1 my WorldMenu is broken and a âfallback World Menuâ appears. "World discoveredWorldMenuâ says that UIThemeWatery2 does not understand smallWindowIcon, that is sent by ContactListEditor class>>menuCommandOn: How can i fix that?

Screencast proposition: Watch someone read code.

by Helene Bilbo

Hi, i have a proposition for a Pharo-Screencast: I would love to look over someoneâs shoulder while she/he is *reading* code. A possible plot would be to download something from squeaksource and then trying to make sense out of it - and talking while doing so. (It would also be good to see all the relevant functions of the browser in action). Background: While i have read some books now (blue book, pharo by example, seaside by example, best practice patterns) i have never actually seen people programming. So i absolutely miss the craftsmanship side of things. Anyway thank you for Pharocasts.

I was looking in the Url classes, forget about FileStream (and then forgot about binary). Should this be added to Zinc? I didn't see any save methods there (like Ruby's Mechanize library). I'm going to add it to MIMEDocument and open an issue. Thanks.

The code is actually mostly the work of SÃ©verin Lemaignan, so if we want to integrate his code in Pharo, we should ask him to sign the Pharo licence agreement: http://code.google.com/p/pharo/wiki/ListOfOkCommitters This code is already included in the last version of Squeak.
