About validation

by StÃ©phane Ducasse

Hi I read the chapter on validation of the mentoring course book of andres valloud. http://www.lulu.com/fr/fr/shop/andres-valloud/a-mentoring-course-on-smallta… And I love this extension of SUnit. I loved the idea when I saw it for the first time at Lugano (presentation of Leandro Caniglia). I encourage everybody to read it. Now does anybody implemented in Pharo the SUnit extension? I would like to play with it and eventually write a chapter on it for the next book. The idea is so good. Stef

[ANN] Barcode project with initial EAN13

by Torsten Bergmann

Hi, didnt know Barcodes are so easy to implement in Smalltalk. So I started with EAN13 barcode together with unit tests. Project lives on: http://smalltalkhub.com/#!/~TorstenBergmann/Barcode You can also load it using the config browser in Pharo 2.0 now. It is already usable - thanks to the power of Pharo. Short Guide: ------------------------------------------------------------------------------------------------ To instantiate: BarcodeEAN13 value: '2109876543210' You can get the binarySequence of a barcode: (BarcodeEAN13 value: '2109876543210') binarySequence calcuate the checksum (last digit: (BarcodeEAN13 value: '2109876543210') computeChecksum or visualize the barcode: BarcodeEAN13 example asForm asMorph openInWorld or to write to a file: PNGReadWriter putForm: BarcodeEAN13 example asForm onFileNamed: 'sample.png' ------------------------------------------------------------------------------------------------ Feel free to extent with other barcode types. Have fun T.
