Issue Details

Provide a clear description of the problem, including the following key
questions:

What did you do?

When running :YcmCompleter GetParent within a cpp file, I am seeing "ValueError: Supported commands are:..." which doesn't include GetParent. According to the readme, GetParent should be supported for cpp files though. GoToDeclaration and the rest are working

Include steps to reproduce here.

Open a cpp file with eg vim -Nu /path/to/YCM/vimrc_ycm_minimal main.cpp (I am using bazel + hedronvision compile commands generator to get a compile_commands.json, but the error will be present without any compile flags)
Run :YcmCompleter GetParent
Behold

GetParent was supported in the legacy libclang completer but cannot be provided by clangd. It’s essentially deprecated at this point.

whoisdylan · 2022-12-13T17:42:42Z

Roger, thank you. I ask bc I'm interested in adding a way to get "breadcrumbs" of the current function/method I'm in a la visual studio and others (see https://i.stack.imgur.com/wu4kP.png) using the LSP and GetParent seemed like a good entry point.

@puremourning do you have any thoughts on how one could go about adding this feature? My vimscript fu is weak, but I was thinking of using YCM commands to update the status line, or if needed a separate plugin that talks LSP and maybe plugins into airline/lightline. I've seen some ppl implement this (eg vista + coc) but not with YCM integrated yet sadly

puremourning · 2022-12-13T17:51:59Z

I think it is possible to do using the document symbols data when supporting the "hierarchical" data response. the server provides a whole hierarchy and you can sort of walk that using the current cursor position.

ycmd doesn't currently support that. Using it to implement a GetParent subcommand might be simple, but I suspect that it would be better to implement some sort of "GetBreadcrumbs" request. In a simple form it could just return the symbol names, but it could also return say a list of positions you can jump to. That would be a fair amount more work of course, though it might be worth it.

I'll re-open this as a feat req.
