Hi Pharoers You are lucky. The "Pharo booklet collection" edited by S. Ducasse is arriving... Are you ready to read nice and focused booklets? You can find at http://files.pharo.org/books/ in beta version: - Smacc: the Smalltalk Compiler Compiler by J. Brant, T. Goubier, J. Lecerf and S. Ducasse. - Glorp: the Object Relational Mapper framework by E. Maringolo, N. Pratt and R. Withney All the book material is hosted on https://github.com/SquareBracketAssociates so you can contribute! Fix typos and propose new material. We are planning a booklet on Magritte, Reddit in 10 cool classes, Voyage, and Mocking with BabyMock and Mocketry, XML (but we need a writer) and potentially PetitParser. If you have material for a tutorial and you would like to be part of the Pharo Booklet Collection contact S. Ducasse. S. Ducasse
