C++ overloaded functions don't seem to complete properly

[colliderman]

Hi all,

I've only recently started using nvim-cmp and have got it working mostly well with C++, Clangd, and the built in neovim lsp, however I'm having the following issue:

When a function has multiple argument types, the completion window shows something like "2 overloads" for the description.

Then when I select the function, the functions are displayed

but when I select one it doesn't autofill the arguments for me, to allow for easy tabbing through them.

If a function doesn't have an overload, then when I select it, it auto fills the arguments and I can start typing to fill in the first argument, hit tab, type out the second argument etc.

Is this is expected behaviour or if not, maybe a setting that I haven't set properly?

I have the same issue. Has there ever been a solution?

I confirm that there is an "issue" with the overloads.Propably some manual handling is neede in order to autocomplete the correct part of the helping window.

A workaround it to pass ""--completion-style=detailed" in the lsp configuration.

Well I started debuging this issue and it seems it is a clangd issue, the insertText returned by clangd is not what we expect

In the [] keymap I inspected the selected item, the code bellow.

The output of this code in the :messages is the following

49 detail = "[5 overloads]",
50 filterText = "find_first_not_of",
51 insertText = "find_first_not_of($0)",
52 insertTextFormat = 2,
53 kind = 2,
54 label = " find_first_not_of",
55 labelDetails = {
56 detail = "(…)"
57 },
58 score = 0.93680763244629,
59 sortText = "40902d60find_first_not_of",
60 textEdit = {
61 newText = "find_first_not_of($0)",
62 range = {
63 ["end"] = {
64 character = 6,
65 line = 42
66 },
67 start = {
68 character = 6,
69 line = 42
70 }
71 }
72 }
73 }
74 {
75 documentation = {
76 kind = "markdown",
77 value = "find_first_not_of(const Tp &svt, size_type pos = 0) -> _If_sv<Tp, size_type>"
78 },
79 filterText = " ",
80 insertText = "const",
81 label = "const Tp &svt",
82 preselect = true,
83 word = ""
84 }
