SciSmalltalk in Squeak

Hi,
I have SciSmalltalk mostly working in Squeak, by adding a compatibility package with:
- a dumb Announcer/Announcement classes (announcing nothing)
- Number>** extensions

There is still one thing that annoys me, the transcripting at end of tests sends BlockClosure>>asText which fails in Squeak
I can define it too in the compatibility package, but is the transcripting really necessary?

Anyway, asText is just too much:
1) asText adds no emphasis, so is a void operation.
2) the first thing #show: will do is send asString to the text, so even if there would have been some intermediate emphasis, they would have vanished
I suggest using printString rather than asText

Also, here:
show: self class name asByteString
asByteString is a very un-common message (see how many senders of it...)
This one would work equally well:
show: self class name
So I suggest removing asByteString sends

Re: SciSmalltalk in Squeak

Hi Nicolas,
perhaps you might want to add a spec for: #squeak "or however thats called" do:[spec repository: 'http://www.smalltalkhub.com/mc/SergeStinckwich/SciSmalltalk/main'. spec package: 'Math-SqueakPrerequisite']. part to the baseline to ensure that this package is at least loaded, when one downloads the complete project. or something more complicated; its just a rough and untried idea.

Hi again,
i thought i could perhaps make a little documentation page in the git wiki, where i describe the packages in a sentence and where everybody can easily hook in their own docu for a package. for this id like to know , whether this compatibility package needs to be loaded in a certain sequence, that is needs it to be loaded first or last?

Re: SciSmalltalk in Squeak

The proper way is to use Metacello.
So just add a #squeak section to the ConfigurationOfSciSmalltalk, and maybe a #pharo section too because the hyperbolic functions are already in Squeak kernel.
It's reasonnable to load the Prerequisite first (though it's required for ODE only right now).

Hi Nicolas,
i added this to a new '0.7-baseline', and also a 'Math-Quaternion' with: [spec requires: 'Math-Complex']. as i dont have squeak at the moment, it would be nice if you could check whether that works as you intended, youd need to fetch version:'0.7-baseline' or #development though as i have not yet updated the stable. please feel free to change that (perhaps an ode requires in the squeak section or so) or update the stable version. fwiw <friendly grin> i tell that only because it took myself awhile to learn that in sciSmalltalk it is expected that one changes these things,if they make sense, by oneself, i'm not responsible for the config. btw there are a few dependencies on dhb in the ComplexTests.
best regards

Thanks!

I'll try and have a look in Squeak, don't bother too much about it.

And yes, there are dependencies... That means that we should separate some Math-Tests-ComplexExtensions...

Hi,
i just uploaded ConfigurationOfSciSmalltalk no 67, that defines a new stable version, which should also work for squeak, at least the tests seem to work.
