Craig, You and SmartReferenceStream are effectively assuming that user==programmer; I submit it is in our interest to many ordinary users of Smalltalk applications. All that should be required is to have code that is newer than the stream, and neither user nor developer should be bothered with conversions. What you are doing on the fly should be done at the time of the layout change by the developer of the class(es) being serialized.

Of course. I'm referring to this inane argument y'all have been having about whether to have case-statement support "in the image". The entire compiler can be an optional module (with the case statement stuff in yet another module separate from that), so the debate is moot. -C -- Craig Latta www.netjam.org/resume +31 06 2757 7177 + 1 415 287 3547

[Pharo-project] Need your point of view on FSPath * and others

by StÃ©phane Ducasse

Colin I'm continuing adding comments to FS. 1- A question about FSPath class>>* aString ^ self with: aString I would like to deprecated FSPath class>>* and use with: since this is the message and What do you think? I really prefer for static analysis point of view not to pollute numerical behavior with others. Avoiding ad-hoc polymorphism will help us to build static checker in the future. 2- Then I was wondering if it would not be good to have validating creation methods (FSPath * 'parent/child/') isRelative true (FSPath * '/parent/child/') isAbsolute false because the string is not checked FSPath * '/parejhkjhhg %% ^%$%^(%$546547675 nt??child/' I saw that there is readFrom: aStream delimiter: aCharacter so I created an unchecking instance creation category and I added with: and * in it. And added comments 3- Then finally the following confuses me (FSPath with: 'parent/child/') isRelative true (FSPath with: '/parent/child/') isRelative true (FSPath with: '') isRelative false Either with: create relative path or isRelative is not consistent. If with: creates relative path then the last one should be true or isRelative should return false on the second one. ? 4 - about FSPath root we have root "Return the relative root path" ^ self with: '' FSPath root returns / and I like that Now what about defining root as root ^ self with: '/' It would be more consistent. Now it breaks everything. So I did not do it :) May be I'm tired after 4 ours teaching and 6 hours train. Thanks for your time Stef

This new Transcript is not a Stream. It is a logger, that can log both to screen and to file. The stream like protocol is just for compatibility. Besides, the usual mechanisms for separating view and model are not used on pourpuse, this doesn't rely on a particular GUI. It is more like Transcripter (i.e. the emergency evaluator).

Re: [Pharo-project] [squeak-dev] Re: Cog VM -- Thanks and Performance / Optimization Questions

by Igor Stasenko

It seems that you guys (Stephane & Juan) both making same mistake. :) You trying to assign multiple different roles to Transcript at once: - be a stream - be a GUI element (can draw/update itself on a screen).. Hey.. Transcript is not a swiss knife! It is just a stream (kind of special one), but other than that.. it is just a stream. And what you see on a screen - it is just a view of it. So, Juan it is cool that you have better Transcript... still it having same deficiencies which i shown to Stephane not long ago, and tried to convince him that Transcript is a stream, not a window. A Transcript window is just a view of real transcript. And i think this is quite easy to make this separation and have sound model.
