Re: [Pharo-users] Serial Port

by David T. Lewis

There should be no license concern. The named serial support is provided in the SerialPlugin, and the update is of course MIT. Background is here: http://bugs.squeak.org/view.php?id=7266 I don't think that patches are included in the oscog branch yet (but I am not able to check right now, sorry). In any case, don't worry about the license.

Yes so I would ban the code and we will fix it ourselves. We do not want to end in 30 different variant of the MIT license. They should not have change the license like that.... Error is repeating itself.

Re: [Pharo-users] Serial Port

I haven't looked at the official license.txt, but the summary looks quite a bit different than what I (or the GNU foundation) consider "the" MIT license, at http://www.jclark.com/xml/copying.txt. Not that I'm a lawyer or my opinion means anything at all here.

Re: [Pharo-users] Serial Port

by Joan GÃ¼ell

Hi Stef, As you can see at http://info.scratch.mit.edu/Source_Code, the Scratch license seems to be MIT. Textually: "The Scratch source code license allows you to distribute derivative works based on the Scratch source code for non-commercial uses subject to the following restrictions: you cannot use the word "Scratch" to refer to derivative works (except in the phrase "Based on Scratch from the MIT Media Laboratory"), you cannot use the Scratch logo or the official (copyrighted) Scratch cat in derivative works, you cannot implement the ability to upload projects to any MIT Scratch website (currently, http://scratch.mit.edu) copies or derivative works must retain the Scratch copyright notice and license, and you must make the source code for derivative works available. This is just a summary; the full license is in the file "license.txt" included in the source code download package. The purpose of these restrictions is to avoid confusion in the Scratch user community between the official version of Scratch (supported by the Lifelong Kindergarten group) and experimental variations. We are happy the share our source code, but we want to protect the Scratch brand and our user community." You can find the license.txt file attached. Cheers, Joan.

Serial Port

by Joan GÃ¼ell

Hello We are developing software to interact with small robots for educational purposes. To do this we need to use the serial port. SerialPort class that includes Pharo does not work on mac or linux, because itÂ´s not able to open ports by name. It would be interesting that future versions include a SerialPort that would work in these circumstances. we are using since a time aÂ´go the plugin that comes with Scratch, with this we just copy the plugins in the folder of the VM, the Plugin that comes with the VM Scrath, and add to the image of the image classes of Scratch , ScratchPlugin and SerialPort2.Up to date this has worked on all VM including the latest Cog. It works on Linux, Mac or Windows.We wory that future versions will lose support. The source code for the plugins can be found on: http://info.scratch.mit.edu/Source_Code ScratchPluginSrc1.4.zip Joan GÃ¼ell jguell(a)e-citilab.eu Joan GÃ¼ell jguell(a)e-citilab.eu

Re: [Pharo-users] Scrolling in a Morphic game

by Benjamin

I do not know if an API exist for this kind of stuff, but it could be really cool to add one ^^ I think that you should basically add a drawing method which take a rectangle as a parameter and display this rectangle from your original world's representation. For scrolling, just adjust the rectangle. I'm really interested in this kind of work, so let me know how your work progress :) Good luck, Ben On Jan 26, 2011, at 2:11 AM, Aidan Gauland wrote: > Hello, > > I am developing a game in Morphic -- nothing serious; just a spare > time project -- and I have come to a tricky part: the viewport.

TestMock v-9 published; now works with Pharo 1.1.1

by Anindya Haldar

Dear Smalltalkers, I am glad to make an updated version (v9) of the mocking framework TestMock available with added Pharo 1.1.1 support. Previously reported v8 issues arising from the deprecation of KeyedSet and some other changes with TestCase and Boolean classes in Pharo 1.1.1 have been fixed. This version continues to work with Pharo 1.0 and Seaside-2.8 dev images as before. Here is the link to the project: http://www.squeaksource.com/TestMock.html Happy smalltalking!
