GoTo Definition for marked template type not working as expected

In the term std::optional<types::nr_rrc::BandList>, I mark BandList and hit Go to Definition. I would expect that this jumps to types::nr_rrc::BandList, but it jumps to std::optional.

Do I miss something here?

The Language Server Protocol currently only accepts a single position as input for the go-to-definition request, not a range.

Assuming you’ve selected the range BandList in the forward direction, such that your cursor is between the t and >, it’s this cursor position that’s sent.

Clangd then needs to decide whether to use the > or the t for targeting. It tries the character to the right of the cursor first, i.e. the >, which is associated with the class template, so it navigates to the class template.

I agree this behaviour is suboptimal. Hopefully, LSP can add support for sending the entire range in https://github.com/microsoft/language-server-protocol/issues/1029.

I have encountered similiar problems.

Thanks for @HighCommander4 's explanation, I have found the reason and known how to a workaround it.

For me, the “go to definition” doesn’t work correctly since I have a habit of double clicking on the BandList, then the cursor is automatically placed at the end of BandList. For my case, the workaround is just to put the cursor in the middle of BandList and don’t double click.
