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/
              https://microsoft.github.io/language-server-protocol/

       clangd accepts flags on the commandline, and in the CLANGD_FLAGS environment variable.

       USAGE: clangd [options]

       OPTIONS:

       Generic Options:

       --help                          - Display available options (--help-hidden for more)

       --help-list                      -  Display  list of available options (--help-list-hidden
              for more)

       --version                       - Display the version of this program

       clangd compilation flags options:

       --compile-commands-dir=<string> - Specify a path to  look  for  compile_commands.json.  If
              path is invalid, clangd will look in the current directory and parent paths of each
              source file

       --query-driver=<string>          -  Comma  separated  list  of  globs  for   white-listing
              gcc-compatible  drivers  that  are  safe  to execute. Drivers matching any of these
              globs     will     be     used     to     extract     system     includes.     e.g.
              /usr/bin/**/clang-*,/path/to/repo/**/g++-*

       clangd feature options:

       --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

       --background-index               -  Index project code in the background and persist index
              on disk.

       --clang-tidy                    - Enable clang-tidy diagnostics

       --clang-tidy-checks=<string>    - List of clang-tidy checks to  run  (this  will  override
              .clang-tidy files). Only meaningful when -clang-tidy flag is on

       --completion-style=<value>      - Granularity of code completion suggestions

       =detailed
              -    One  completion item for each semantically distinct completion, with full type
              information

       =bundled
              -    Similar  completion  items  (e.g.  function  overloads)  are  combined.   Type
              information shown where possible

       --fallback-style=<string>         -  clang-format  style  to  apply  by  default  when  no
              .clang-format file is found

       --header-insertion=<value>      - Add #include directives when accepting code completions

       =iwyu  -   Include what you use. Insert the owning header for  top-level  symbols,  unless
              the header is already directly included or the symbol is forward-declared

       =never -   Never insert #include directives as part of code completion

       --header-insertion-decorators    -  Prepend  a circular dot or space before the completion
              label, depending on whether an include line will be inserted or not

       --limit-results=<int>           - Limit the number of results returned by clangd. 0  means
              no limit (default=100)

       --suggest-missing-includes       -  Attempts  to  fix  diagnostic errors caused by missing
              includes using index

       clangd miscellaneous options:

       -j=<uint>                       - Number of async workers used by clangd. Background index
              also uses this many workers.

       --pch-storage=<value>            - Storing PCHs in memory increases memory usages, but may
              improve performance

       =disk  -   store PCHs on disk

       =memory
              -   store PCHs in memory

       clangd protocol and logging options:

       --log=<value>                   - Verbosity of log messages written to stderr

       =error
              -   Error messages only

       =info  -   High level execution tracing

       =verbose
              -   Low level details

       --offset-encoding=<value>       - Force the offsetEncoding used for  character  positions.
              This bypasses negotiation via client capabilities

       =utf-8
              -   Offsets are in UTF-8 bytes

       =utf-16
              -   Offsets are in UTF-16 code units

       --pretty                        - Pretty-print JSON output
