One more proposal. Thanks Hilaire =Title= Worksheet toolkit =Level (beginner, intermediate, advanced)= Intermediate =Mentor= Hilaire Fernandes =Second mentor= =Description= A Smalltalk based spreadsheet toolkit with a basic editor to: add/delete cells edit cells formula render aspect May depends on PetitParser to parse cells formula. =Technical Details= The toolkit should be customizable. =Benefits to the Student= Learn how to modelize a spreadseet, to design a view and editor. Learn how to design an editor tool: model, view and controller. =Benefits to the Community= A spreadsheet toolkit. Le 29/03/2013 14:24, Sean P.

Title: Dialect-Portable Monticello Level: intermediate Possible mentor: Sean DeNigris Possible second mentor: ? Description Extend FileTree and Cypress to handle dialect feature differences like namespaces vs. prefixes Technical Details The pieces are all available and a proof of concept has been done, but what's required is a deeper look to integrate the idea consistent with the existing design Benefits to the Student The student will get a deep understanding that ultimately, no matter how many layers are on top, most data boils down to text, which can be freed from wherever it lives, to go wherever it's needed. Also, the student will have the opportunity to contribute to a key core open source tool, with all the community involvement that implies. Benefits to the Community There are many great libraries for Squeak/Pharo vs. VW that would be extremely useful on the other side (like Xstreams - which has an older version on Squeak/Pharo, and PDF Artefact). There is very little preventing near-automatic porting between the ecosystems, and this project would address that. ----- Cheers, Sean -- View this message in context: http://forum.world.st/More-GSoC-ideas-wanted-3-days-left-tp4678353p4678863.… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Thanks Sean. I understand your motivation (and I agree with them), but well... we need to adjust the process before make this kind of changes. You wouldn't believe the amount of things that became affected with that small change :S anyway, this will be backported to 2.0 in summer release (or perhaps before), we wont need to wait until next year :) Esteban On Mar 29, 2013, at 1:12 AM, "Sean P.
