GSoC Proposal - Improve Code Completion

by Nahuel Garbezza

Hi everyone! I'm trying to apply to GSoC and I have a proposal about Code completion. I would like to share with you: https://docs.google.com/document/d/1R8zAq415UCqtn3AoAcRGDSQFZ_5QgL88nQu6R7g… I know you guys have a lot of ideas around code completion, so any kind of feedback is appreciated. Thanks! Nahuel

Sorry to be skeptical, but as much as I admire Richard Eng's work, since it is April 1st (which is April Fool's Day in the U.S.) I am a bit skeptical of this story. :>{ I hope it's true but .. mike

In the quest of Smacc idioms

by Stephane Ducasse

Hi I'm trying to understand what are the idioms in Smacc when converting from ANTLR ######### the case of * ######################## Function = â(â (',' Arguments )* â)â should be transformed into Function : <name> "(" 'leftParen' _ArgumentsOption ")" 'rightParen' {{}} ; _ArgumentsOption : | Arguments ; Arguments : Expression 'argument' | Arguments "," Expression 'argument' ; Here since there is a recursion in Arguments the instance variable containing a list of argument will be added to the FunctionNode Pay attention that Expression 'argument' should not have a {{}} nor its parent rule. ######### the case of + ######################## Function = â(â Arguments + â)â should be transformed into Function : <name> "(" 'leftParen' _ArgumentsOption ")" 'rightParen' {{}} ; _ArgumentsOption : Arguments ; Arguments : Expression 'argument' | Arguments "," Expression 'argument' ; ######### the case of ? ######################## Function = â(â Arguments+ â)â should be transformed into Function : <name> "(" 'leftParen' _ArgumentsOption ")" 'rightParen' {{}} ; _ArgumentsOption : | Arguments ; Arguments : Expression 'argument' ; Is there a more compact way to express? Thierry do you have example of *, + , ? in the grammar? Stef

Hi, Thanks for sharing. There is any link to the HPE site on the news about investing 1.2 billion in the R & D Research Lab?
