[Pharo-project] [OT] Rewrite in C++

by Torsten Bergmann

Found a program currently written in Squeak called TaalPulse (see http://taalpulse.net) >From the news page: "For the technically inclined, the new version of TaalPulse is being written in C++ using the Qt 4.4 user-interface toolkit. " In the forum the developer Guillaume Pothier explains his decision: http://sourceforge.net/mailarchive/forum.php?thread_name=8caa8ded0804172152… "Squeak was the only truly portable solution, and it still is to this day" "Although I haven't programmed in C++ for years I am confident it will be easier than Smalltalk" Could not really understand the move to C++, it's sad and at least this rings some bells that Pharo has to be different than Squeak ...

[Pharo-project] Seaside and Apache

I made this work in Monticello.impl-mtf.579 I'll update the LPF script so you can start using it (and yes, I'm still working on freeing LPF from the pbwiki) The merge tool shows anything that overwrites something outside of the package (other than an override) as a conflict. -- Matthew Fulmer -- http://mtfulmer.wordpress.com/

Re: [Pharo-project] Re: about ifEmptyOrNil:

by Keith Hodges

When I think about this issue in different terms I think it makes more sense. No matter how perfect my code I find myself interfacing to things like MySQL where it is happy to return nil when it means an empty string. someValue ifNotUsefulUse: [ defaultValue ]. but then the question "what does useful mean", at which point it becomes easier to define clearly what is not useful i.e. someValue ifNilOrEmpty: [ defaultValue ]. If I had known this call existed I would use it much more because b := someValue ifEmpty: [ defaultValue ]. doesnt work (see earlier discussions on squeak-dev) regards Keith
