Why building a Rust LSP is hard

  Using a JSON TCP connection for what on Windows would be direct function calls (COM) or in Eclipse would be direct function calls between Java modules always felt a bit gross.

  Enter hell: LSP assumes that it's the source of truth, but you still need to access the filesystem yourself, and do it in a synchronized way

  LSP is an example of utterly horrid technical design.

  Stop letting Microsoft design protocols and APIs. They are so. bad. at. it.

    I've never looked into LSP, how would you design it?

      Start with synchronous function calls instead of JSON. Microsoft knows how to do that - they invented COM.

      Well for one I wouldn't design it so both the LSP and the editor need a synchronized view of the underlying file.
