clangd – manual page for clangd 10
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:
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
- –help-list – Display list of available options (–help-list-hidden for more)
- –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++-*
- –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
- –background-index – Index project code in the background and persist index on disk.
- – 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
- –header-insertion=<value> – Add #include directives when accepting code completions
- – 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
- –limit-results=<int> – Limit the number of results returned by clangd. 0 means no limit (default=100)
- -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
- –pch-storage=<value> – Storing PCHs in memory increases memory usages, but may improve performance
- – store PCHs on disk
- =memory
- – store PCHs in memory
- –log=<value> – Verbosity of log messages written to stderr
- =error
- =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
- =utf-8
- – Offsets are in UTF-8 bytes
- =utf-16
- – Offsets are in UTF-16 code units
- =utf-32
- – Offsets are in unicode codepoints
- –path-mappings=<string> – Translates between client paths (as seen by a remote editor) and server paths (where clangd sees files on disk). Comma separated list of ‘<client_path>=<server_path>’ pairs, the first entry matching a given path is used. e.g. /home/project/incl=/opt/include,/home/project=/workarea/project
- –pretty – Pretty-print JSON output
