Subject: 30.0.50; Eglot: codeAction.resolveSupport capability is incorrect
Date: Tue, 25 Jul 2023 18:01:12 +0300

I'm using a recent snapshot build.

When trying to use Eglot on Rust code (with the rust-analyzer LSP
server), it crashes complaining about the InitializationOptions message
being misformed.

This is due to this commit:
https://git.savannah.gnu.org/cgit/emacs.git/commit/lisp/progmodes/eglot.el?id=3b7273f4ae3623962c5d5fdc922a62af1136f448

resolveSupport is supposed to be a list, not a boolean, see here:
https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_codeAction

I'm not sure what properties Eglot supports here, so I'm not certain on
what the correction should be.

João, any comments here?

I think this was already fixed by:

commit bc1e7b9b8e681346e407c4dc32272a0bf4decd68
Author: João Távora <joaotavora <at> gmail.com>
Date:   Wed Jul 12 10:11:34 2023 +0100

    Eglot: fix advertisement of textDocument.codeAction.resolveSupport

    See https://github.com/joaotavora/eglot/issues/1255.

    * lisp/progmodes/eglot.el (eglot-client-capabilities):
    Use correct format for textDocument.codeAction.resolveSupport.

I just didn't mention the debbugs id.

João
