Crate fml_lsp 

Language server for the FHIR Mapping Language.

• diagnostics: syntax, compile and type problems as you type;
• completion: elements after . (from the type of the variable, followed through the path), variables in scope, groups after then, transforms after =, types after :, keywords;
• hover: the type of a variable or an element, a group’s signature, a transform’s description;
• go to definition, find references and rename for variables and groups;
• signature help for transforms and group calls;
• the outline (document symbols), formatting, and semantic tokens for colouring.

Server does no I/O: it takes JSON-RPC messages and returns what to send back, so a host can run it over standard input and output (run_stdio) or over a WebSocket.

use fml_lsp::Server;
use serde_json::json;

let mut server = Server::with_release(fml_check::Release::R5);
server.handle(&json!({"jsonrpc": "2.0", "id": 1, "method": "initialize", "params": {"capabilities": {}}}));
let replies = server.handle(&json!({
    "jsonrpc": "2.0",
    "method": "textDocument/didOpen",
    "params": {"textDocument": {"uri": "file:///map.fml", "languageId": "fml", "version": 1, "text": "group G(source src : Patient) {\n  src.nmae -> src.name;\n}\n"}}
}));
assert_eq!(replies[0]["method"], "textDocument/publishDiagnostics");
