Re: [Pharo-users] [Athens] Finding if a line passes through a specific pixel .

Unless I am blind I see loads of bezier methods, none that detects whether a point belong to a curve.

Re: [Pharo-users] Nautilus pkg-pane regression in pharo 3.0?

Yes, I'm aware... I still do not decide if is a bug or a feature :) Honestly, the problem is the collision of functionality for <- and ->. And I don't know how to handle it. Suggestions?

How to load the PetitPHPParser?

by HernÃ¡n Morales Durand

Loading in Pharo 2.0 gives warning with lots of dependencies: This package depends on the following classes: PPCompositeParserTest PPCompositeParser You must resolve these dependencies before you will be able to load these definitions: PPPHPCoreGrammar ... I have used: Gofer new squeaksource: 'PetitPHPParser'; package: 'ConfigurationOfPetitPHPParser'; load. (Smalltalk at: #ConfigurationOfPetitPHPParser) perform: #loadDefault. Cheers, HernÃ¡n
