Subject: jsonrpc: Check if parameters are in line with the spec
Date: Sun, 01 Sep 2024 18:26:02 +0200

I failed to implement an LSP extension to Eglot, because my function
sent a required parameter as a string instead of an array containing a
single element: the string.  In the end it turned out that this was my
fault, because according to the JSON specification: "If present,
parameters for the rpc call MUST be provided as a Structured
value. Either by-position through an Array or by-name through an
Object."  https://www.jsonrpc.org/specification#parameter_structures

Would it be possible to extend jsonrpc.el to check the params argument
of jsonrpc-request, jsonrpc-notify, and jsonrpc-async-request whether it
is a structured value?  And if it is not, then guide the programmer to
the above URL with a warning.

Thank you.
