clangd - manual page for clangd 8
DESCRIPTION
OVERVIEW: clangd is a language server that provides IDE-like features to editors.
It should be used via an editor plugin rather than invoked directly. For more information,
see:
https://clang.llvm.org/extra/clangd.html
https://microsoft.github.io/language-server-protocol/
USAGE: clangd [options]
OPTIONS:
Color Options:
-color - Use colors in output
(default=autodetect)
General options:
-aarch64-neon-syntax - Choose style of NEON code to emit from
AArch64 backend:
=generic
- Emit generic NEON assembly
=apple - Emit Apple-style NEON assembly
-all-scopes-completion - If set to true, code completion will
include index symbols that are not defined in the scopes (e.g. namespaces) visible
from the code completion point. Such completions can insert scope qualifiers.

supported by subtarget
