If this feature has changed in emacs 30, then I would not have seen it yet (I am not tracking emacs/eglot development a lot). I am working on a language server for Debian packaging (called `debputy`). The Debian packaging files consists of several different file formats with cross references between the formats. As a consequence, I built my language server to be a "polyglot" (multi-language). While testing with eglot, I noticed that my language server was not informed of all changes. As far as I can see, eglot spawns a language server per file format (major mode) and then only informs the language server of events (didOpen/didChange) for that major mode. This happens even through it is exactly the same command + args for both major modes. The next result is that my language server when used via emacs + eglot, requires the user to save a file before the language server can "see" the effect when you are working in a different file. I was a bit in doubt whether the spec accounted for polyglot language servers, so I asked in the LSP github for clarification. They made the argument that a language server should be able to see events for other file formats and suggested that I contacted you (the eglot maintainers) about this (https://github.com/microsoft/language-server-protocol/issues/1964). They acknowledged this was implicit and then listed the two key features they saw as supporting this implicit requirement (both of them boils down to DocumentSelector as I read it). I tried a static registration with a DocumentSelector on `**/debian/*` (I think it was hover docs, though it might have been completion), but my debugging suggested that my instances did not get didOpen/didChange events "across" the file formats even with this registration. Can we work towards a solution where I can ask eglot to provide didOpen/didChange events across formats? :) Best regards, Niels
