LanguageServerProtocol
This is a Swift library for interacting with Language Server Protocol. It contains type definitions and utilities useful for both server- and client-side projects.
This project was derived from SwiftLSPClient. That library mixes both the underlying protocol handling with a client-level abstraction. It is no longer officially supported.
If you are looking for a way to interact with servers, you probably want to use the higher-level LanguageClient.
Typing Approach
Where possible, this library matches the LSP spec. However, there are some additional types present in this library that aren't in the spec. This is caused by the use of anonymous structures.
This library models these cases using nested structures and/or the TwoTypeOption and ThreeTypeOption types.

]Extra Features
For the most part, this library strives to be a straightforward version of the spec in Swift. There are a few places, however, where it just makes sense to pull in some extra functionality.
Snippet: makes it easier to interpret the contents of completion resultsSemanticTokensClient: helps to consume Semantic Token information
Supported Features
The LSP specification is large, and this library currently does not implement it all. The intention is to support the 3.x specification, but be as backwards-compatible as possible with pre-3.0 servers.
