I just started following this Dev mailing list, and I saw that 'AST Everywhere' and 'Reflectivity' were mentioned as very promising (I already know about Slots). Can someone in a nutshell please describe these developments? Thanks,
Right now, the compiler uses it's own AST, Syntax highlighting uses a very minimal token stream (and it's own parser), the refactoring engine has one, too. And then there is Bytecode which is used by the Debugger, for example.
As a first step we plan to use the Refactoring AST for everything (Compiler, Refactoring, Syntax highlighting )
I keep forgetting to ask - does the Refactoring AST have an equivalent of Squeak's FutureNode?
No.
(It's not semantically necessary to have one to support futures; it's a performance enhancer.)
Now that sound *very* odd. An AST Node is by definition something that is a grammatical element of the language. If you write down the grammar of Smalltalk, there is no "Future" there, so in the AST there is none modeled, either. No, I know nothing about the Future implementation in Squeak⦠but a Future node in the AST sounds extremely strange. Marcus
