lsp-imenu don't show method args

[myrgy]

Hi all,

Previously I had similar issue #329, which were caused by imenu settings, but seems like imenu was changes and now I can't seem arguments.

In case of C++ it's possible to have a bunch of methods with different arguments. In that case imenu is useless because I can't use it for navigation.
Could you please help me to adjust this behaviour.

Thank you in advance!

(I use lsp + ccls)

@MaskRay , seems like imenu results depend from cursor position. Is it desired behavior or a bug?
(when cursor is on the method - then I have only one result in imenu)

In hierarchical document symbol support of ccls,

https://github.com/maskray/ccls/blob/master/src/messages/textDocument_documentSymbol.cc#L131

          ds.name = def->Name(false); // foo
          ds.detail = def->Name(true); // ns::foo but no arguments

• on ccls's side, detail may include function arguments if some initialization option is provided, e.g. documentSymbol.verboseDetail (bikeshedding on the name welcomed)
• in lsp-imenu.el, name is used to create imenu entries. it may be useful to have an option to switch to detail

@MaskRay , thank you for answer!

@MaskRay I might be missing something but here it is what I see as a ccls output(no detail). Jdt ls response is at the bottom

With DocumentSymbol[], the qualified name can be inferred from the hierarchy, so I think ds->detail = def->Named(true); (qualified name) might not be useful. Just changed ccls to use ds->detail = def->detailed_name (qualified name with args)`.

Assuming this to be fixed. @myrgy if you hit the same issue with some other server please file a bug in the server's repo.
