bug#68710: 30.0.50; eglot not sending the correct configuration to LSP

[Pedro A. Aranda]

I'm using eglot for LaTeX and Python3 in a project
where I need both. My .dir-locals.el file in this case is
((nil
  . ((eglot-workspace-configuration
      . (:pylsp (:plugins (:jedi_completion (:include_params t
:fuzzy t)
                                            :pylint (:enabled 
:json-false)))
                :texlab (:completion (:matcher "prefix")))
      ))
  ))

which is directly taken from the manual.


Apparently, eglot doesn't send the right configuration to the LSP.

In the case of the LaTeX LSP, it issending:

DEBUG - Opening document file:///home/paag/tmp/horst/mix.tex...
DEBUG - < 
{"jsonrpc":"2.0","method":"workspace/didChangeConfiguration","params":{"settings":{"pylsp":{"plugins":{"jedi_completion":{"include_params":true,"fuzzy":true},"pylint":{"enabled":false}}},"texlab":{"completion":{"matcher":"prefix"}}}}}

                    "plugins": Object {

                            "include_params": Bool(true),
                        },
                        "pylint": Object {
                            "enabled": Bool(false),
                        },
                    },
                },
                "texlab": Object {
                    "completion": Object {
                        "matcher": String("prefix"),
                    },
                },
            },
        },
    },
)

While it should only be sending the 'texlab' section as:

{"jsonrpc":"2.0","method":"workspace/didChangeConfiguration","params":{"settings":{"completion":{"matcher":"prefix"}}}}
