Re: [Pharo-users] Does vm shipped with Squeak 4.0 support closures? [cross posted]

by Mariano Martinez Peck

Hi Tom. Squeak V4.0 as far as I understood (I may be wrong) doesn't support closures as it is the same as Squeak 3.10.2 but with changes in the license. Squeak trunk (not 4.0) do support closures, the same as Pharo. For the Pharo side, it is easy. From http://www.pharo-project.org/pharo-download you can download the image and the VM and it will work. Seaside one click images are based on Pharo, so the same applies for Seaside. A closure enable VM should work also with non-closure images (like squeak v4.0) as I understand (again, I may be wrong). I saw a mail from Chris in squeak-dev saying he has a problem with the SqueakVM...so I am not sure if the VM shipped supports closures or not. Hope this helps.

Hi Smalltalkers! Maybe you are not aware of what our selection to this year GSoC really means for the Smalltalk community. And I wasn't aware completely until few hours. Just to give you an example, even such big organizations like Ruby or PHP where not selected. From this viewpoint you can see what we have achieved. Some people said and still says that Smalltalk is old and that it is dead. Ok, we have been selected by the major Informatics and Software company all over the world. The point is that ESUG and the Smalltalk community was selected because of the seriousness mixed with passion of all the application, project and ideas. We have an incredible high quality list of ideas and mentors. We have a unique opportunity to show the rest of the world why we love Smalltalk, why it is much better than other alternatives, etc. So, we invite all of you to make this happens. Thanks to everybody for all the congratulations and nice words!!!

Does vm shipped with Squeak 4.0 support closures? [cross posted]

by Tom.X.Porter＠gmail.com

I know that Pharo (or at least Pharo with seaside) requires a VM with closure support, and the Pharo download page gives access to a vm 4.2.2b1 that supports them. Squeak V4.0 has a vm 4.2.3.b1u, but I am unclear if it was build with support for closures. I just thought I would check on the pharo list and with the mouse folks as well, as I run both on my mac. I guess I might need both VM's. Thanks to both for all the hard work! Tom P.

Adding a new reserved word

by Carla F. Griggio

Hi everyone! I want to add a new reserved word to a Pharo image. I tried to find the code that gives special treatment to words like nil, true, false, self, etc. and add my new reserved word, but as though I tried to immitate some things, I was not successful. Â¿What could be the right way to do this? Â¿Can I add a reserved word just adding some code on a Pharo image? Thanks! Carla. PS: The object of doing this is nothing serious, I just want to make a friend laugh with a silly joke :)

Yes, there certainly is a lot of stuff that can be removed (I'm currently working on removing the requires algorithm and making it reloadable from an external package).

This way, you can write much cleaner code as you can call your methods on the literal floats that the compiler generates: 4.5 addCent: ... In addition, you should have a look at double dispatch and especially Dan's parametarized double dispatch used for the operators. This allows you to actually use the math symbols... with your own classes if it makes sense: e.g. 4.5 + 5 cents Plus is implemented like this: + aNumber "Primitive.

Subclassing Float?

by Ch Lamprecht

Hello, I tried to build a subclass of Float without success. More precisely, I did not find out how to build instances from it. Is subclassing Float something I should not do? I am trying to build objects, that represent Audio frequencies. They should behave like Floats but have some additional methods like 'addCent: anOffset' or 'deltaCent: aFrequency' (cent refers to a logarithmic scale used to express frequency relations). Cheers, Chris
