Crate nifty_lsp 

A language server for Nifty: diagnostics, completion, signature help, semantic highlighting, the document outline, go to definition, find references and highlighting the name under the cursor. Every file of a project folder is analysed together, so names resolve across files.

Modules

context 🔒

What kind of code the cursor is in, worked out from the tokens before it. Code being typed rarely parses, so this reads tokens rather than the syntax tree: it only needs to know which blocks, calls and brackets are open and what came last.

document 🔒

One source file of a project: its text, its syntax tree, and conversion between byte offsets and LSP positions.

features 🔒

One module per LSP feature. Each turns a Document into protocol types and knows nothing about the connection.

index 🔒

Every name in a project’s files, each tied to the declaration it refers to when one exists in the project. Built-in elements, built-in types, fields reached through a value and implicit members have no declaration until the type checker exists, so they stay unresolved.

project 🔒

The files of one program, analysed together: a project folder’s .nf files, or a single file outside any project. A name declared in one file resolves in all of them.

server 🔒

The message loop: keeps open documents up to date and answers requests about them.

signature 🔒

The parameters of whatever a call names: a built-in element or function, or a function, view or struct declared in any file of the project.

workspace 🔒

The open documents and the projects they belong to. A document inside a project folder is analysed with every other .nf file of that project, open or not; a document outside one is a project of its own. Open documents’ text wins over what is saved on disk.
