Haskell library for the Microsoft Language Server Protocol.

An implementation of the types, and basic message server to allow language implementors to support the Language Server Protocol for their specific language.

An example of this is for Haskell via the Haskell Language Server, at https://github.com/haskell/haskell-language-server

lsp

lsp is a library for building language servers, handling:

• JSON-RPC transport
• Keeping track of the document state in memory with the Virtual File System (VFS)
• Responding to notifications and requests via handlers
• Setting the server capabilities in the initialize request based on registered handlers
• Dynamic registration of capabilities
• Cancellable requests and progress notifications
• Publishing and flushing of diagnostics

It is part of the lsp family of packages, along with lsp-test and lsp-types
