Like this we ensure the correct behavior for all existing code in the image even if we change the compiler to always return nil. >> I will have to check all 60 empty blocks with arguments one by one. >> Most of them are used in exception handlers that do not use the return >> result, so this should mostly be a non-issue. > > I would :) > but let us see what the others think for now. > > Lukas I'm still lookfing for the _ Â => := changes :) Ok, I will provide a fix for Pharo 1.1 this morning.

If this is the consensus I can commit a slice that fixes the compiler and that rewrites the existing code. I will have to check all 60 empty blocks with arguments one by one. Most of them are used in exception handlers that do not use the return result, so this should mostly be a non-issue.

With respect, it is not your place to dictate working methods. You are correct that one can easily over-use workspaces and under-use class methods. However, one can also over-use class methods when a new test case is more appropriate. >> >> Rather than removing basic features, we should add capabilities to encourage good practice by making things as easy as possible. Dolphin's IDE extensions are a nice feature that I *really* miss in Pharo. One thing I added is a way to create test case methods based on a currently selected method. Each class can specify a TestCase subclass, and the methods were automatically named based on the selected method's name; the code is generated and proposed for optional compiling with warning of conflicts. >> >> Bill >> >> >> -----Original Message----- >> From: pharo-project-bounces(a)lists.gforge.inria.fr [mailto:pharo-project-bounces@lists.gforge.inria.fr] On Behalf Of Ramiro Diaz Trepat >> Sent: Wednesday, December 16, 2009 8:44 AM >> To: Pharo-project(a)lists.gforge.inria.fr >> Subject: Re: [Pharo-project] [newbee] How do I save the contents of a Workspace? >> >> I really miss that feature. >> In my oppinion it is very useful when you regularly use different images, or when you frequently rebuild your development image from newer versions. >> Also, I wonder if the Package Browser should be removed completely since it does not even open now when you select it as preferred. >> >> >> -----Original Message----- >> From: pharo-project-bounces(a)lists.gforge.inria.fr [mailto:pharo-project-bounces@lists.gforge.inria.fr] On Behalf Of StÃ©phane Ducasse >> Sent: 16 December 2009 12:07 >> To: Pharo-project(a)lists.gforge.inria.fr >> Subject: Re: [Pharo-project] [newbee] How do I save the contents of a Workspace? >> >> for me it was political/educational to remove it. >> >> I saw too many people having expressions in workspace and not in class methods (not versioned with the code). >> because if this is really important why not put it in a class method? >> Then you load the code and of course you do not get the magic example beacuse they were in the wonderfull scripts left in the other images..... >> >> Stef >> >> On Dec 16, 2009, at 12:51 PM, CÃ©drick BÃ©ler wrote: >> >>> I think this is a valuable feature. >>> >>> Should we save in a particular file extension (.wst ? or simply text files ?) so that we can also have load opening from a a list of files of that format.

[Pharo-project] misconception addendum :)

by StÃ©phane Ducasse

Hi this night I was thinking about a frequent misconception about pharo. It is easy to think that pharo wants just plain good engineering to open grey window. Pharo really wants to be innovative and this at all level. We want better/faster/leaner and more powerful code at all level: UI, network... I heard that some people think that we are against MVC but we are not We are against isMorphic ifTrue: ifFalse:. Pharo does not have to be in the seaside niche and it will not be. But if this makes the life easier to some perfect. Now pharoers do not have to either pick web or the rest. We want to make sure that if someone wants to build an alternative windowing system he can do it easily. (BTW alain showed to us some fun and powerful sketches of using cairo (via rome) to have multiple windowing skeleton.) Now we certainly do not have the knowledge for everything but this is not by a lack of vision. So if you want to build this future don't get us wrong. Stef PS: I still have in mind the vision of Smalltalk by dan: a system that a simple person could understand (for me it means beauty, documentation and elegance of the solutions).
