MVP

[matklad]

The MVP for libsyntax2.0 is to create a small library for code editors, which provides some basic functionality, depending only on the syntax. Specifically, the plan is to port stuff that lives in fall here and here.

• parse most of the common Rust syntax
• incremental relexing (should be trivial to do, in contrast with incremental reparsing)
• extend selection
• file structure
• project symbols
• add impl action

Is this up to date? It would be nice to outline a path to an alpha version that we can announce on Rust internals and publish on the vscode marketplace... I think many people (like me) would get enthusiastic about a language server that you can actually build yourself and it may even attract new contributors!

Also, from the discussion about the future of the compiler on the internals forum I got the impression that some people in the Rust team would really like the compiler to be more modular... Which aligns very well with the goals of Rust Analyzer. On the internals thread it even seemed like Rust Analyzer could replace Rust's current parser/AST at a given point. Following the same trend as Salsa, Chalk and Polonius, Rust Analyser could become an experimental modular Rust frontend to be eventually integrated in the compiler. Is there a plan to work together with @nikomatsakis (or other people in the Rust team) to bring Rust Analyzer to a usable state?
