Does emacs-cquery work with remote project (with tramp)? #12

Hi,

The situation: Emacs is running on desktop machine A and the project Foo is at remote machine B. And B's OS could be different with A. And currently, the project Foo is accessed on A's emacs by tramp-mode. So with compile_command.json provided for project Foo, could emacs-cquery work? Or how can I get it work for such case?
What I have tried: I've got emacs-cquery worked on machine A if project Foo is also at machine A. And when I move project Foo to machine B and open it, I get following error: File mode specification error: (error Process lsp-cquery<1> not running)

Thanks!

The design I have in mind for this is that the remote machine runs cquery server daemon, and a LSP middleware handles the communication between the local machine and the remote machine, such that the local machine thinks that cquery server daemon is running locally.

Such a tool could be generic and work for any lsp server.

Right now, lsp-mode doesn't support running clients in remote buffers. They're using the more feature-rich spawn-process variant (for its stderr/stdin separation) instead of the more stripped-down function that calls Tramp file handlers.

LSP clients also can't be shared / forwarded by lsp-mode, either, as all IO is done over a pipe.

I've been idly plucking away at getting Tramp support working with lsp-mode proper. Can't find a clever solution for logging stderr into a separate buffer, though, so that'll probably be unavailable on any Tramp-driven setup.

Does lsp-mode TCP connection work?

(defun lsp--make-tcp-connection (name command command-fn host port stderr) (lambda (filter sentinel)

If not, @zhongweiy can you make an issue to https://github.com/emacs-lsp/lsp-mode ?

Sorry for late reply.

@MaskRay How can I check whether lsp-mode TCP connection work? @jaelsasser If Tramp-driven setup doesn't work, is there any alternative for a remote project?

There is a generic issue about lsp-mode https://github.com/emacs-lsp/lsp-mode/issues/197

cquery seems to work reasonably well, if you drop tramp-mode and use sshfsexec instead.
