commit 4525eca32a10046484b5a6dd1f0647927aae2dd6
Author: João Távora <address@hidden>
Commit: João Távora <address@hidden>
Support json.c. API purely based on classes
No more jsonrpc-connect.
This is a big commit because of a data loss problem. It should be at
least two separate commits (json.c-support and new API)
* eglot.el (eglot-server-programs): Rework docstring.
(eglot-handle-request): Don't take ID param
(eglot-lsp-server): No more initargs.
(eglot--interactive): Return 5 args.
(eglot): Take 5 args.
(eglot-reconnect): Pass 6 args to eglot--connect.
(eglot--dispatch): Remove.
(eglot--connect): Take 6 args. Rework.
(eglot-handle-notification): Change all specializations
to use a non-keyword symbol spec.
(eglot-handle-request): Remove ID param from all
specializations. Don't pass ID to jsonrpc-reply.
(eglot--register-unregister): Don't take JSONRPC-ID arg.
Don't pass ID to jsonrpc-reply.
* jsonrpc-tests.el (returns-3, signals-an--32603-JSONRPC-error)
(times-out, stretching-it-but-works)
(json-el-cant-serialize-this, jsonrpc-connection-ready-p)
(deferred-action-intime, deferred-action-toolate)
(deferred-action-timeout): Pass JSON objects compatible with
json.c
(jsonrpc--test-client, jsonrpc--test-endpoint): New classes
(jsonrpc--with-emacsrpc-fixture): Don't use jsonrpc-connect.
(jsonrpc-connection-ready-p): Update signature.
* jsonrpc.el: Rewrite commentary.
(jsonrpc-connection): Rework class.
(jsonrpc-process-connection): Rework class.
(initialize-instance): New methods..
(jsonrpc--json-read, jsonrpc--json-encode): Reindent.
(jsonrpc-connect): Delete.
(jsonrpc--json-read, jsonrpc--json-encode):
New functions for working with json.c
(jsonrpc--process-filter): Call them.
(jsonrpc--unanswered-request-id): New variable.
(jsonrpc--connection-receive): Use jsonrpc--unanswered-request-id
(jsonrpc-connection-send): Take keyword params to build message
instead of message.
(jsonrpc-notify, jsonrpc--async-request-1): Use new
jsonrpc-connection-send.
(jsonrpc-reply): Simplify.
* eglot-tests.el (rls-watches-files, rls-basic-diagnostics)
(rls-hover-after-edit): Correctly compare using string= and
non-keyword symbols.

;; To approach this agnosticism, jsonrpc.el uses objects derived from

+;; applications operating over arbitrary transport infrastructures can
;; specify a subclass of `jsonrpc-connection' and write specific
-;; methods for it. Nevertheless, jsonrpc.el comes built-in with
-;; `jsonrpc-process-connection' class that works both with local
-;; subprocesses (through stdin/stdout) and TCP hosts (using
-;; sockets). This uses some simple HTTP-style envelopping for JSON
-;; objects travelling through the wire.
+;; methods for it.
;;
-;; The entry point `jsonrpc-connect', returns one of these objects by

-;; "contact", which will determine the connection type to make. This
-;; contact can a list of strings (a command and arguments for creating
-;; subprocesses) or a list of the form (HOST PORT-NUMBER PARAMS...)
-;; for connecting via TCP. For the providing the aforementioned
-;; flexibility, it can also be a any object of a subclass of

+;; The `jsonrpc-connection' constructor is the most generic entry

+;; (https://microsoft.github.io/language-server-protocol/specification).

-;; `jsonrpc-connect' returns a connection upon connection. This value
-;; should be saved to be later given to `jsonrpc-notify',
-;; `jsonrpc-reply', `jsonrpc-request' and `jsonrpc-async-request' as a
-;; way of contacting the connected remote endpoint.
+;; Whatever the method used to obtain a `jsonrpc-connection', it is
+;; given to `jsonrpc-notify', `jsonrpc-request' and
+;; `jsonrpc-async-request' as a way of contacting the connected remote

;;
-;; `jsonrpc-connect' is also passed a dispatcher function for handling
-;; handling the contacts asynchronously initiated by the remote
-;; endpoint's, as well as a optional function for cleaning up after
-;; the tear-down of the JSONRPC connection.
+;; For handling remotely initiated contacts, `jsonrpc-connection'
+;; objects hold dispatcher functions that the application should pass
+;; to object's constructor if it is interested in those messages.
;;
;; The JSON objects are passed to the dispatcher after being read by
-;; `json-read' of Emacs's json.el library. They are read as plists,
-;; and, likewise, json.el-compatible plists should be given to
