+ by such Contributor that are necessarily infringed by their
+ Contribution(s) alone or by combination of their Contribution(s)
+ with the Work to which such Contribution(s) was submitted. If You
+ institute patent litigation against any entity (including a
+ cross-claim or counterclaim in a lawsuit) alleging that the Work
+ or a Contribution incorporated within the Work constitutes direct
+ or contributory patent infringement, then any patent licenses
+ granted to You under this License for that Work shall terminate

+ within such NOTICE file, excluding those notices that do not
+ pertain to any part of the Derivative Works, in at least one
+ of the following places: within a NOTICE text file distributed
+ as part of the Derivative Works; within the Source form or
+ documentation, if provided along with the Derivative Works; or,
+ within a display generated by the Derivative Works, if and
+ wherever such third-party notices normally appear. The contents
+ of the NOTICE file are for informational purposes only and
+ do not modify the License. You may add Your own attribution
+ notices within Derivative Works that You distribute, alongside
+ or as an addendum to the NOTICE text from the Work, provided
+ that such additional attribution notices cannot be construed
+ as modifying the License.
+
+ You may add Your own copyright statement to Your modifications and
+ may provide additional or different license terms and conditions
+ for use, reproduction, or distribution of Your modifications, or
+ for any such Derivative Works as a whole, provided Your use,
+ reproduction, and distribution of the Work otherwise complies with
+ the conditions stated in this License.
+
+ 5. Submission of Contributions. Unless You explicitly state otherwise,
+ any Contribution intentionally submitted for inclusion in the Work
+ by You to the Licensor shall be under the terms and conditions of
+ this License, without any additional terms or conditions.

+ Contributor provides its Contributions) on an "AS IS" BASIS,
+ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+ implied, including, without limitation, any warranties or conditions
+ of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+ PARTICULAR PURPOSE. You are solely responsible for determining the
+ appropriateness of using or redistributing the Work and assume any
+ risks associated with Your exercise of permissions under this License.
+
+ 8. Limitation of Liability. In no event and under no legal theory,
+ whether in tort (including negligence), contract, or otherwise,
+ unless required by applicable law (such as deliberate and grossly
+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the
+ Work (including but not limited to damages for loss of goodwill,
+ work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses), even if such Contributor
+ has been advised of the possibility of such damages.
+
+ 9. Accepting Warranty or Additional Liability. While redistributing
+ the Work or Derivative Works thereof, You may choose to offer,
+ and charge a fee for, acceptance of support, warranty, indemnity,
+ or other liability obligations and/or rights consistent with this
+ License. However, in accepting such obligations, You may act only
+ on Your own behalf and on Your sole responsibility, not on behalf
+ of any other Contributor, and only if You agree to indemnify,
+ defend, and hold each Contributor harmless for any liability
+ incurred by, or claims asserted against, such Contributor by reason
+ of your accepting any such warranty or additional liability.

+ of the NOTICE file are for informational purposes only and
+ do not modify the License. You may add Your own attribution
+ notices within Derivative Works that You distribute, alongside
+ or as an addendum to the NOTICE text from the Work, provided
+ that such additional attribution notices cannot be construed
+ as modifying the License.
+
+ You may add Your own copyright statement to Your modifications and
+ may provide additional or different license terms and conditions
+ for use, reproduction, or distribution of Your modifications, or
+ for any such Derivative Works as a whole, provided Your use,
+ reproduction, and distribution of the Work otherwise complies with
+ the conditions stated in this License.
+
+ 5. Submission of Contributions. Unless You explicitly state otherwise,

+
+ 8. Limitation of Liability. In no event and under no legal theory,
+ whether in tort (including negligence), contract, or otherwise,
+ unless required by applicable law (such as deliberate and grossly
+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the
+ Work (including but not limited to damages for loss of goodwill,
+ work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses), even if such Contributor
+ has been advised of the possibility of such damages.
+
+ 9. Accepting Warranty or Additional Liability. While redistributing
+ the Work or Derivative Works thereof, You may choose to offer,
+ and charge a fee for, acceptance of support, warranty, indemnity,
+ or other liability obligations and/or rights consistent with this
+ License. However, in accepting such obligations, You may act only

+"""gen_std.py is a tool to generate a lookup table (from qualified names to

+files from cppreference.
+
+Caveats and FIXMEs:
+ - only symbols directly in "std" namespace are added, we should also add std's
+ subnamespace symbols (e.g. chrono).
+ - symbols with multiple variants or defined in multiple headers aren't added,
+ e.g. std::move, std::swap
+
+Usage:
+ 1. Install BeautifulSoup dependency, see instruction:
+ https://www.crummy.com/software/BeautifulSoup/bs4/doc/#installing-beautiful-soup
+ 2. Download cppreference offline HTML files (e.g. html_book_20181028.zip) at
+ https://en.cppreference.com/w/Cppreference:Archives
+ 3. Unzip the zip file from step 2 to directory </cppreference>, you should
+ get a "reference" directory in </cppreference>
+ 4. Run the command:
+ gen_std.py -cppreference </cppreference/reference> > StdSymbolMap.inc

Improvements to clang-query
---------------------------
-- A new command line parameter ``--preload`` was added to
- run commands from a file and then start the interactive interpreter.
-
-- The command ``q`` can was added as an alias for ``quit`` to exit the
- ``clang-query`` interpreter.
-
-- It is now possible to bind to named values (the result of ``let``
- expressions). For example:
-
- .. code-block:: none
-
- let fn functionDecl()
- match fn.bind("foo")
-
-- It is now possible to write comments in ``clang-query`` code. This
- is primarily useful when using script-mode. Comments are all content
- following the ``#`` character on a line:
-
- .. code-block:: none
-
- # This is a comment
- match fn.bind("foo") # This is a trailing comment
-
-- The new ``set print-matcher true`` command now causes ``clang-query`` to
- print the evaluated matcher together with the resulting bindings.
-
-- A new output mode ``detailed-ast`` was added to ``clang-query``. The
- existing ``dump`` output mode is now a deprecated alias
- for ``detailed-ast``
-
-- Output modes can now be enabled or disabled non-exclusively. For example,
-
- .. code-block:: none
-
- # Enable detailed-ast without disabling other output, such as diag
- enable output detailed-ast
- m functionDecl()
-
- # Disable detailed-ast only
- disable output detailed-ast
- m functionDecl()

+ domain.

- <clang-tidy/checks/abseil-duration-factory-float>` check.
+- New :doc:`abseil-duration-conversion-cast

+================
+Getting Involved
+================
+
+:program:`clang-tidy` has several own checks and can run Clang static analyzer
+checks, but its power is in the ability to easily write custom checks.
+
+Checks are organized in modules, which can be linked into :program:`clang-tidy`
+with minimal or no code changes in :program:`clang-tidy`.
+
+Checks can plug into the analysis on the preprocessor level using `PPCallbacks`_
+or on the AST level using `AST Matchers`_. When an error is found, checks can
+report them in a way similar to how Clang diagnostics work. A fix-it hint can be
+attached to a diagnostic message.
+
+The interface provided by :program:`clang-tidy` makes it easy to write useful
+and precise checks in just a few lines of code. If you have an idea for a good
+check, the rest of this document explains how to do this.
+
+There are a few tools particularly useful when developing clang-tidy checks:
+ * ``add_new_check.py`` is a script to automate the process of adding a new
+ check, it will create the check, update the CMake file and create a test;
+ * ``rename_check.py`` does what the script name suggests, renames an existing
+ check;
+ * :program:`clang-query` is invaluable for interactive prototyping of AST
+ matchers and exploration of the Clang AST;
+ * `clang-check`_ with the ``-ast-dump`` (and optionally ``-ast-dump-filter``)
+ provides a convenient way to dump AST of a C++ program.
+
+If CMake is configured with ``CLANG_ENABLE_STATIC_ANALYZER``,
+:program:`clang-tidy` will not be built with support for the
+``clang-analyzer-*`` checks or the ``mpi-*`` checks.
+
+
+.. _AST Matchers: https://clang.llvm.org/docs/LibASTMatchers.html
+.. _PPCallbacks: https://clang.llvm.org/doxygen/classclang_1_1PPCallbacks.html
+.. _clang-check: https://clang.llvm.org/docs/ClangCheck.html
+
+
+Choosing the Right Place for your Check
+---------------------------------------
+
+If you have an idea of a check, you should decide whether it should be
+implemented as a:
+
++ *Clang diagnostic*: if the check is generic enough, targets code patterns that
+ most probably are bugs (rather than style or readability issues), can be
+ implemented effectively and with extremely low false positive rate, it may
+ make a good Clang diagnostic.
+
++ *Clang static analyzer check*: if the check requires some sort of control flow
+ analysis, it should probably be implemented as a static analyzer check.
+
++ *clang-tidy check* is a good choice for linter-style checks, checks that are
+ related to a certain coding style, checks that address code readability, etc.
+
+
+Preparing your Workspace
+------------------------
+
+If you are new to LLVM development, you should read the `Getting Started with
+the LLVM System`_, `Using Clang Tools`_ and `How To Setup Clang Tooling For
+LLVM`_ documents to check out and build LLVM, Clang and Clang Extra Tools with
+CMake.
+
+Once you are done, change to the ``llvm/tools/clang/tools/extra`` directory, and
+let's start!
+
+.. _Getting Started with the LLVM System: https://llvm.org/docs/GettingStarted.html
+.. _Using Clang Tools: https://clang.llvm.org/docs/ClangTools.html
+.. _How To Setup Clang Tooling For LLVM: https://clang.llvm.org/docs/HowToSetupToolingForLLVM.html
+
+
+The Directory Structure
+-----------------------
+
+:program:`clang-tidy` source code resides in the
+``llvm/tools/clang/tools/extra`` directory and is structured as follows:
+
+::
+
+ clang-tidy/ # Clang-tidy core.
+ |-- ClangTidy.h # Interfaces for users.
+ |-- ClangTidyCheck.h # Interfaces for checks.
+ |-- ClangTidyModule.h # Interface for clang-tidy modules.
+ |-- ClangTidyModuleRegistry.h # Interface for registering of modules.
+ ...
+ |-- google/ # Google clang-tidy module.

+ ...
+ |-- tool/ # Sources of the clang-tidy binary.
+ ...

+ ...
+ unittests/clang-tidy/ # Unit tests.
+ |-- ClangTidyTest.h
+ |-- GoogleModuleTest.cpp
+ |-- LLVMModuleTest.cpp
+ |-- ObjCModuleTest.cpp
+ ...
+
+
+Writing a clang-tidy Check
+--------------------------
+
+So you have an idea of a useful check for :program:`clang-tidy`.
+
+First, if you're not familiar with LLVM development, read through the `Getting
+Started with LLVM`_ document for instructions on setting up your workflow and
+the `LLVM Coding Standards`_ document to familiarize yourself with the coding
+style used in the project. For code reviews we mostly use `LLVM Phabricator`_.
+
+.. _Getting Started with LLVM: https://llvm.org/docs/GettingStarted.html
+.. _LLVM Coding Standards: https://llvm.org/docs/CodingStandards.html
+.. _LLVM Phabricator: https://llvm.org/docs/Phabricator.html
+
+Next, you need to decide which module the check belongs to. Modules
+are located in subdirectories of `clang-tidy/
+<https://github.com/llvm/llvm-project/tree/master/clang-tools-extra/clang-tidy/>`_
+and contain checks targeting a certain aspect of code quality (performance,
+readability, etc.), certain coding style or standard (Google, LLVM, CERT, etc.)
+or a widely used API (e.g. MPI). Their names are same as user-facing check
+groups names described :ref:`above <checks-groups-table>`.
+
+After choosing the module and the name for the check, run the
+``clang-tidy/add_new_check.py`` script to create the skeleton of the check and
+plug it to :program:`clang-tidy`. It's the recommended way of adding new checks.
+
+If we want to create a `readability-awesome-function-names`, we would run:
+
+.. code-block:: console
+
+ $ clang-tidy/add_new_check.py readability awesome-function-names
+
+
+The ``add_new_check.py`` script will:
+ * create the class for your check inside the specified module's directory and
+ register it in the module and in the build system;
+ * create a lit test file in the ``test/clang-tidy/`` directory;
+ * create a documentation file and include it into the
+ ``docs/clang-tidy/checks/list.rst``.
+
+Let's see in more detail at the check class definition:
+
+.. code-block:: c++
+
+ ...
+
+ #include "../ClangTidyCheck.h"
+
+ namespace clang {
+ namespace tidy {
+ namespace readability {
+
+ ...
+ class AwesomeFunctionNamesCheck : public ClangTidyCheck {
+ public:
+ AwesomeFunctionNamesCheck(StringRef Name, ClangTidyContext *Context)
+ : ClangTidyCheck(Name, Context) {}
+ void registerMatchers(ast_matchers::MatchFinder *Finder) override;
+ void check(const ast_matchers::MatchFinder::MatchResult &Result) override;
+ };
+
+ } // namespace readability
+ } // namespace tidy
+ } // namespace clang
+
+ ...
+
+Constructor of the check receives the ``Name`` and ``Context`` parameters, and
+must forward them to the ``ClangTidyCheck`` constructor.
+
+In our case the check needs to operate on the AST level and it overrides the
+``registerMatchers`` and ``check`` methods. If we wanted to analyze code on the
+preprocessor level, we'd need instead to override the ``registerPPCallbacks``
+method.
+
+In the ``registerMatchers`` method we create an AST Matcher (see `AST Matchers`_
+for more information) that will find the pattern in the AST that we want to
+inspect. The results of the matching are passed to the ``check`` method, which
+can further inspect them and report diagnostics.
+
+.. code-block:: c++
+
+ using namespace ast_matchers;
+
+ void AwesomeFunctionNamesCheck::registerMatchers(MatchFinder *Finder) {
+ Finder->addMatcher(functionDecl().bind("x"), this);
+ }
+
+ void AwesomeFunctionNamesCheck::check(const MatchFinder::MatchResult &Result) {
+ const auto *MatchedDecl = Result.Nodes.getNodeAs<FunctionDecl>("x");

+(If you want to see an example of a useful check, look at
+`clang-tidy/google/ExplicitConstructorCheck.h
+<https://github.com/llvm/llvm-project/blob/master/clang-tools-extra/clang-tidy/google/ExplicitConstructorCheck.h>`_
+and `clang-tidy/google/ExplicitConstructorCheck.cpp
+<https://reviews.llvm.org/diffusion/L/browse/clang-tools-extra/trunk/clang-tidy/google/ExplicitConstructorCheck.cpp>`_).
+
+
+Registering your Check
+----------------------
+
+(The ``add_new_check.py`` takes care of registering the check in an existing
+module. If you want to create a new module or know the details, read on.)
+
+The check should be registered in the corresponding module with a distinct name:
+
+.. code-block:: c++
+
+ class MyModule : public ClangTidyModule {
+ public:
+ void addCheckFactories(ClangTidyCheckFactories &CheckFactories) override {
+ CheckFactories.registerCheck<ExplicitConstructorCheck>(
+ "my-explicit-constructor");
+ }
+ };
+
+Now we need to register the module in the ``ClangTidyModuleRegistry`` using a
+statically initialized variable:
+
+.. code-block:: c++
+
+ static ClangTidyModuleRegistry::Add<MyModule> X("my-module",
+ "Adds my lint checks.");
+
+
+When using LLVM build system, we need to use the following hack to ensure the
+module is linked into the :program:`clang-tidy` binary:
+
+Add this near the ``ClangTidyModuleRegistry::Add<MyModule>`` variable:
+
+.. code-block:: c++
+
+ // This anchor is used to force the linker to link in the generated object file
+ // and thus register the MyModule.
+ volatile int MyModuleAnchorSource = 0;
+
+And this to the main translation unit of the :program:`clang-tidy` binary (or
+the binary you link the ``clang-tidy`` library in)
+``clang-tidy/tool/ClangTidyMain.cpp``:
+
+.. code-block:: c++
+
+ // This anchor is used to force the linker to link the MyModule.
+ extern volatile int MyModuleAnchorSource;
+ static int MyModuleAnchorDestination = MyModuleAnchorSource;
+
+
+Configuring Checks
+------------------
+
+If a check needs configuration options, it can access check-specific options
+using the ``Options.get<Type>("SomeOption", DefaultValue)`` call in the check
+constructor. In this case the check should also override the
+``ClangTidyCheck::storeOptions`` method to make the options provided by the
+check discoverable. This method lets :program:`clang-tidy` know which options
+the check implements and what the current values are (e.g. for the
+``-dump-config`` command line option).
+
+.. code-block:: c++
+
+ class MyCheck : public ClangTidyCheck {
+ const unsigned SomeOption1;
+ const std::string SomeOption2;
+
+ public:
+ MyCheck(StringRef Name, ClangTidyContext *Context)
+ : ClangTidyCheck(Name, Context),
+ SomeOption(Options.get("SomeOption1", -1U)),
+ SomeOption(Options.get("SomeOption2", "some default")) {}
+
+ void storeOptions(ClangTidyOptions::OptionMap &Opts) override {
+ Options.store(Opts, "SomeOption1", SomeOption1);
+ Options.store(Opts, "SomeOption2", SomeOption2);
+ }
+ ...
+
+Assuming the check is registered with the name "my-check", the option can then
+be set in a ``.clang-tidy`` file in the following way:
+
+.. code-block:: yaml
+
+ CheckOptions:
+ - key: my-check.SomeOption1
+ value: 123
+ - key: my-check.SomeOption2
+ value: 'some other value'
+
+If you need to specify check options on a command line, you can use the inline
+YAML format:
+
+.. code-block:: console
+
+ $ clang-tidy -config="{CheckOptions: [{key: a, value: b}, {key: x, value: y}]}" ...
+
+
+Testing Checks
+--------------
+
+To run tests for :program:`clang-tidy` use the command:
+
+.. code-block:: console
+
+ $ ninja check-clang-tools
+
+:program:`clang-tidy` checks can be tested using either unit tests or
+`lit`_ tests. Unit tests may be more convenient to test complex replacements
+with strict checks. `Lit`_ tests allow using partial text matching and regular
+expressions which makes them more suitable for writing compact tests for
+diagnostic messages.
+
+The ``check_clang_tidy.py`` script provides an easy way to test both
+diagnostic messages and fix-its. It filters out ``CHECK`` lines from the test
+file, runs :program:`clang-tidy` and verifies messages and fixes with two
+separate `FileCheck`_ invocations: once with FileCheck's directive
+prefix set to ``CHECK-MESSAGES``, validating the diagnostic messages,
+and once with the directive prefix set to ``CHECK-FIXES``, running
+against the fixed code (i.e., the code after generated fix-its are
+applied). In particular, ``CHECK-FIXES:`` can be used to check
+that code was not modified by fix-its, by checking that it is present
+unchanged in the fixed code. The full set of `FileCheck`_ directives
+is available (e.g., ``CHECK-MESSAGES-SAME:``, ``CHECK-MESSAGES-NOT:``), though
+typically the basic ``CHECK`` forms (``CHECK-MESSAGES`` and ``CHECK-FIXES``)
+are sufficient for clang-tidy tests. Note that the `FileCheck`_
+documentation mostly assumes the default prefix (``CHECK``), and hence
+describes the directive as ``CHECK:``, ``CHECK-SAME:``, ``CHECK-NOT:``, etc.
+Replace ``CHECK`` by either ``CHECK-FIXES`` or ``CHECK-MESSAGES`` for
+clang-tidy tests.
+
+An additional check enabled by ``check_clang_tidy.py`` ensures that
+if `CHECK-MESSAGES:` is used in a file then every warning or error
+must have an associated CHECK in that file. Or, you can use ``CHECK-NOTES:``
+instead, if you want to **also** ensure that all the notes are checked.
+
+To use the ``check_clang_tidy.py`` script, put a .cpp file with the
+appropriate ``RUN`` line in the ``test/clang-tidy`` directory. Use
+``CHECK-MESSAGES:`` and ``CHECK-FIXES:`` lines to write checks against
+diagnostic messages and fixed code.
+
+It's advised to make the checks as specific as possible to avoid checks matching
+to incorrect parts of the input. Use ``[[@LINE+X]]``/``[[@LINE-X]]``
+substitutions and distinct function and variable names in the test code.
+
+Here's an example of a test using the ``check_clang_tidy.py`` script (the full
+source code is at `test/clang-tidy/google-readability-casting.cpp`_):
+
+.. code-block:: c++
+
+ // RUN: %check_clang_tidy %s google-readability-casting %t
+
+ void f(int a) {
+ int b = (int)a;
+ // CHECK-MESSAGES: :[[@LINE-1]]:11: warning: redundant cast to the same type [google-readability-casting]
+ // CHECK-FIXES: int b = a;
+ }
+
+To check more than one scenario in the same test file use
+``-check-suffix=SUFFIX-NAME`` on ``check_clang_tidy.py`` command line or
+``-check-suffixes=SUFFIX-NAME-1,SUFFIX-NAME-2,...``.
+With ``-check-suffix[es]=SUFFIX-NAME`` you need to replace your ``CHECK-*``
+directives with ``CHECK-MESSAGES-SUFFIX-NAME`` and ``CHECK-FIXES-SUFFIX-NAME``.
+
+Here's an example:
+
+.. code-block:: c++
+
+ // RUN: %check_clang_tidy -check-suffix=USING-A %s misc-unused-using-decls %t -- -- -DUSING_A
+ // RUN: %check_clang_tidy -check-suffix=USING-B %s misc-unused-using-decls %t -- -- -DUSING_B
+ // RUN: %check_clang_tidy %s misc-unused-using-decls %t
+ ...
+ // CHECK-MESSAGES-USING-A: :[[@LINE-8]]:10: warning: using decl 'A' {{.*}}
+ // CHECK-MESSAGES-USING-B: :[[@LINE-7]]:10: warning: using decl 'B' {{.*}}
+ // CHECK-MESSAGES: :[[@LINE-6]]:10: warning: using decl 'C' {{.*}}
+ // CHECK-FIXES-USING-A-NOT: using a::A;$
+ // CHECK-FIXES-USING-B-NOT: using a::B;$
+ // CHECK-FIXES-NOT: using a::C;$
+
+
+There are many dark corners in the C++ language, and it may be difficult to make
+your check work perfectly in all cases, especially if it issues fix-it hints. The
+most frequent pitfalls are macros and templates:
+
+1. code written in a macro body/template definition may have a different meaning
+ depending on the macro expansion/template instantiation;
+2. multiple macro expansions/template instantiations may result in the same code
+ being inspected by the check multiple times (possibly, with different
+ meanings, see 1), and the same warning (or a slightly different one) may be
+ issued by the check multiple times; :program:`clang-tidy` will deduplicate
+ _identical_ warnings, but if the warnings are slightly different, all of them
+ will be shown to the user (and used for applying fixes, if any);
+3. making replacements to a macro body/template definition may be fine for some
+ macro expansions/template instantiations, but easily break some other
+ expansions/instantiations.

+
+
+Running clang-tidy on LLVM
+--------------------------
+
+To test a check it's best to try it out on a larger code base. LLVM and Clang
+are the natural targets as you already have the source code around. The most
+convenient way to run :program:`clang-tidy` is with a compile command database;
+CMake can automatically generate one, for a description of how to enable it see
+`How To Setup Clang Tooling For LLVM`_. Once ``compile_commands.json`` is in
+place and a working version of :program:`clang-tidy` is in ``PATH`` the entire
+code base can be analyzed with ``clang-tidy/tool/run-clang-tidy.py``. The script
+executes :program:`clang-tidy` with the default set of checks on every
+translation unit in the compile command database and displays the resulting
+warnings and errors. The script provides multiple configuration flags.
+
+.. _How To Setup Clang Tooling For LLVM: https://clang.llvm.org/docs/HowToSetupToolingForLLVM.html
+
+
+* The default set of checks can be overridden using the ``-checks`` argument,
+ taking the identical format as :program:`clang-tidy` does. For example
+ ``-checks=-*,modernize-use-override`` will run the ``modernize-use-override``
+ check only.
+
+* To restrict the files examined you can provide one or more regex arguments
+ that the file names are matched against.
+ ``run-clang-tidy.py clang-tidy/.*Check\.cpp`` will only analyze clang-tidy
+ checks. It may also be necessary to restrict the header files warnings are
+ displayed from using the ``-header-filter`` flag. It has the same behavior
+ as the corresponding :program:`clang-tidy` flag.
+
+* To apply suggested fixes ``-fix`` can be passed as an argument. This gathers
+ all changes in a temporary directory and applies them. Passing ``-format``
+ will run clang-format over changed lines.
+
+
+On checks profiling
+-------------------
+
+:program:`clang-tidy` can collect per-check profiling info, and output it
+for each processed source file (translation unit).
+
+To enable profiling info collection, use the ``-enable-check-profile`` argument.
+The timings will be output to ``stderr`` as a table. Example output:
+
+.. code-block:: console
+
+ $ clang-tidy -enable-check-profile -checks=-*,readability-function-size source.cpp
+ ===-------------------------------------------------------------------------===
+ clang-tidy checks profiling
+ ===-------------------------------------------------------------------------===
+ Total Execution Time: 1.0282 seconds (1.0258 wall clock)
+
+ ---User Time--- --System Time-- --User+System-- ---Wall Time--- --- Name ---
+ 0.9136 (100.0%) 0.1146 (100.0%) 1.0282 (100.0%) 1.0258 (100.0%) readability-function-size
+ 0.9136 (100.0%) 0.1146 (100.0%) 1.0282 (100.0%) 1.0258 (100.0%) Total
+
+It can also store that data as JSON files for further processing. Example output:
+
+.. code-block:: console
+
+ $ clang-tidy -enable-check-profile -store-check-profile=. -checks=-*,readability-function-size source.cpp
+ $ # Note that there won't be timings table printed to the console.
+ $ ls /tmp/out/
+ 20180516161318717446360-source.cpp.json
+ $ cat 20180516161318717446360-source.cpp.json
+ {
+ "file": "/path/to/source.cpp",
+ "timestamp": "2018-05-16 16:13:18.717446360",
+ "profile": {
+ "time.clang-tidy.readability-function-size.wall": 1.0421266555786133e+00,
+ "time.clang-tidy.readability-function-size.user": 9.2088400000005421e-01,
+ "time.clang-tidy.readability-function-size.sys": 1.2418899999999974e-01
+ }
+ }
+
+There is only one argument that controls profile storage:
+
+* ``-store-check-profile=<prefix>``
+
+ By default reports are printed in tabulated format to stderr. When this option
+ is passed, these per-TU profiles are instead stored as JSON.
+ If the prefix is not an absolute path, it is considered to be relative to the
+ directory from where you have run :program:`clang-tidy`. All ``.`` and ``..``
+ patterns in the path are collapsed, and symlinks are resolved.
+
+ Example:
+ Let's suppose you have a source file named ``example.cpp``, located in the
+ ``/source`` directory. Only the input filename is used, not the full path
+ to the source file. Additionally, it is prefixed with the current timestamp.
+
+ * If you specify ``-store-check-profile=/tmp``, then the profile will be saved
+ to ``/tmp/<ISO8601-like timestamp>-example.cpp.json``
+
+ * If you run :program:`clang-tidy` from within ``/foo`` directory, and specify
+ ``-store-check-profile=.``, then the profile will still be saved to
+ ``/foo/<ISO8601-like timestamp>-example.cpp.json``

+.. _integrates clang-tidy: https://www.jetbrains.com/help/clion/clang-tidy-checks-support.html
+
+CLion_ 2017.2 and later `integrates clang-tidy`_ as an extension to the
+built-in code analyzer. Starting from 2018.2 EAP, CLion allows using
+:program:`clang-tidy` via Clangd. Inspections and applicable quick-fixes are
+performed on the fly, and checks can be configured in standard command line
+format. In this integration, you can switch to the :program:`clang-tidy`
+binary different from the bundled one, pass the configuration in
+``.clang-tidy`` files instead of using the IDE settings, and configure
+options for particular checks.
+
+.. _KDevelop: https://www.kdevelop.org/
+.. _kdev-clang-tidy: https://github.com/KDE/kdev-clang-tidy/
+
+KDevelop_ with the kdev-clang-tidy_ plugin, starting from version 5.1, performs
+static analysis using :program:`clang-tidy`. The plugin launches the
+:program:`clang-tidy` binary from the specified location and parses its
+output to provide a list of issues.
+
+.. _QtCreator: https://www.qt.io/
+.. _Clang Code Model: https://doc.qt.io/qtcreator/creator-clang-codemodel.html
+
+QtCreator_ 4.6 integrates :program:`clang-tidy` warnings into the editor
+diagnostics under the `Clang Code Model`_. To employ :program:`clang-tidy`
+inspection in QtCreator, you need to create a copy of one of the presets and
+choose the checks to be performed in the Clang Code Model Warnings menu.

+
+`MS Visual Studio`_ has a native clang-tidy-vs_ plugin and also can integrate
+:program:`clang-tidy` by means of three other tools. The `ReSharper C++`_
+extension, version 2017.3 and later, provides seamless :program:`clang-tidy`
+integration: checks and quick-fixes run alongside native inspections. Apart
+from that, ReSharper C++ incorporates :program:`clang-tidy` as a separate
+step of its code clean-up process. `Visual Assist`_ build 2210 includes a
+subset of :program:`clang-tidy` checklist to inspect the code as you edit.
+Another way to bring :program:`clang-tidy` functionality to Visual Studio is
+the `Clang Power Tools`_ plugin, which includes most of the
+:program:`clang-tidy` checks and runs them during compilation or as a separate
+step of code analysis.

+.. _Vim: https://www.vim.org/
+
+Emacs24_, when expanded with the Flycheck_ plugin, incorporates the
+:program:`clang-tidy` inspection into the syntax analyzer. For Vim_, you can
+use Syntastic_, which includes :program:`clang-tidy`, or `A.L.E.`_,
+a lint engine that applies :program:`clang-tidy` along with other linters.

+:program:`clang-tidy` is integrated in CPPDepend_ starting from version 2018.1
+and CPPCheck_ 1.82. CPPCheck integration lets you import Visual Studio
+solutions and run the :program:`clang-tidy` inspection on them. The
+CodeChecker_ application of version 5.3 or later, which also comes as a plugin_
+for Eclipse, supports :program:`clang-tidy` as a static analysis instrument and

+abseil-duration-addition
+========================
+
+Check for cases where addition should be performed in the ``absl::Time`` domain.
+When adding two values, and one is known to be an ``absl::Time``, we can infer
+that the other should be interpreted as an ``absl::Duration`` of a similar
+scale, and make that inference explicit.
+
+Examples:
+

+
+ // Original - Addition in the integer domain
+ int x;
+ absl::Time t;
+ int result = absl::ToUnixSeconds(t) + x;
+

+abseil-time-comparison
+======================
+
+Prefer comparisons in the ``absl::Time`` domain instead of the integer domain.
+
+N.B.: In cases where an ``absl::Time`` is being converted to an integer,
+alignment may occur. If the comparison depends on this alignment, doing the
+comparison in the ``absl::Time`` domain may yield a different result. In
+practice this is very rare, and still indicates a bug which should be fixed.
+
+Examples:
+
+.. code-block:: c++
+
+ // Original - Comparison in the integer domain
+ int x;
+ absl::Time t;
+ if (x < absl::ToUnixSeconds(t)) ...
+
+ // Suggested - Compare in the absl::Time domain instead
+ if (absl::FromUnixSeconds(x) < t) ...

+abseil-time-subtraction
+=======================
+
+Finds and fixes ``absl::Time`` subtraction expressions to do subtraction
+in the Time domain instead of the numeric domain.
+
+There are two cases of Time subtraction in which deduce additional type
+information:
+
+- When the result is an ``absl::Duration`` and the first argument is an
+ ``absl::Time``.
+- When the second argument is a ``absl::Time``.
+
+In the first case, we must know the result of the operation, since without that
+the second operand could be either an ``absl::Time`` or an ``absl::Duration``.
+In the second case, the first operand *must* be an ``absl::Time``, because
+subtracting an ``absl::Time`` from an ``absl::Duration`` is not defined.
+
+Examples:
+
+.. code-block:: c++
+
+ int x;
+ absl::Time t;
+
+ // Original - absl::Duration result and first operand is a absl::Time.
+ absl::Duration d = absl::Seconds(absl::ToUnixSeconds(t) - x);
+
+ // Suggestion - Perform subtraction in the Time domain instead.
+ absl::Duration d = t - absl::FromUnixSeconds(x);
+
+
+ // Original - Second operand is an absl::Time.
+ int i = x - absl::ToUnixSeconds(t);
+
+ // Suggestion - Perform subtraction in the Time domain instead.
+ int i = absl::ToInt64Seconds(absl::FromUnixSeconds(x) - t);

modernize-use-override
======================
+Adds ``override`` (introduced in C++11) to overridden virtual functions and
+removes ``virtual`` from those functions as it is not required.
-Use C++11's ``override`` and remove ``virtual`` where applicable.
+``virtual`` on non base class implementations was used to help indiciate to the
+user that a function was virtual. C++ compilers did not use the presence of
+this to signify an overriden function.
+
+In C++ 11 ``override`` and ``final`` keywords were introduced to allow
+overridden functions to be marked appropriately. Their presence allows
+compilers to verify that an overridden function correctly overrides a base
+class implementation.
+
+This can be useful as compilers can generate a compile time error when:
+
+ - The base class implementation function signature changes.
+ - The user has not created the override with the correct signature.

+Invoking ``-self`` on super instances in initializers is a common programmer
+error when the programmer's original intent is to call a superclass
+initializer. Failing to call a superclass initializer breaks initializer
+chaining and can result in invalid object initialization.

+openmp-exception-escape
+=======================
+
+Analyzes OpenMP Structured Blocks and checks that no exception escapes
+out of the Structured Block it was thrown in.
+
+As per the OpenMP specification, a structured block is an executable statement,
+possibly compound, with a single entry at the top and a single exit at the
+bottom. Which means, ``throw`` may not be used to to 'exit' out of the
+structured block. If an exception is not caught in the same structured block
+it was thrown in, the behaviour is undefined.
+
+FIXME: this check does not model SEH, ``setjmp``/``longjmp``.

+=======================
+
+Finds OpenMP directives that are allowed to contain a ``default`` clause,
+but either don't specify it or the clause is specified but with the kind
+other than ``none``, and suggests to use the ``default(none)`` clause.
+
+Using ``default(none)`` clause forces developers to explicitly specify data
+sharing attributes for the variables referenced in the construct,
+thus making it obvious which variables are referenced, and what is their
+data sharing attribute, thus increasing readability and possibly making errors
+easier to spot.
+
+Example

+
+ // ``for`` directive can not have ``default`` clause, no diagnostics.
+ void n0(const int a) {

-Getting Involved
-================
-
-:program:`clang-tidy` has several own checks and can run Clang static analyzer
-checks, but its power is in the ability to easily write custom checks.
-
-Checks are organized in modules, which can be linked into :program:`clang-tidy`
-with minimal or no code changes in :program:`clang-tidy`.
-
-Checks can plug into the analysis on the preprocessor level using `PPCallbacks`_
-or on the AST level using `AST Matchers`_. When an error is found, checks can
-report them in a way similar to how Clang diagnostics work. A fix-it hint can be
-attached to a diagnostic message.
-
-The interface provided by :program:`clang-tidy` makes it easy to write useful
-and precise checks in just a few lines of code. If you have an idea for a good
-check, the rest of this document explains how to do this.
-
-There are a few tools particularly useful when developing clang-tidy checks:
- * ``add_new_check.py`` is a script to automate the process of adding a new
- check, it will create the check, update the CMake file and create a test;
- * ``rename_check.py`` does what the script name suggests, renames an existing
- check;
- * :program:`clang-query` is invaluable for interactive prototyping of AST
- matchers and exploration of the Clang AST;
- * `clang-check`_ with the ``-ast-dump`` (and optionally ``-ast-dump-filter``)
- provides a convenient way to dump AST of a C++ program.
-
-If CMake is configured with ``CLANG_ENABLE_STATIC_ANALYZER``,
-:program:`clang-tidy` will not be built with support for the
-``clang-analyzer-*`` checks or the ``mpi-*`` checks.

-Choosing the Right Place for your Check
----------------------------------------
-
-If you have an idea of a check, you should decide whether it should be
-implemented as a:
-
-+ *Clang diagnostic*: if the check is generic enough, targets code patterns that
- most probably are bugs (rather than style or readability issues), can be
- implemented effectively and with extremely low false positive rate, it may
- make a good Clang diagnostic.
-
-+ *Clang static analyzer check*: if the check requires some sort of control flow
- analysis, it should probably be implemented as a static analyzer check.
-
-+ *clang-tidy check* is a good choice for linter-style checks, checks that are
- related to a certain coding style, checks that address code readability, etc.
-
-
-Preparing your Workspace
-------------------------
-
-If you are new to LLVM development, you should read the `Getting Started with
-the LLVM System`_, `Using Clang Tools`_ and `How To Setup Tooling For LLVM`_
-documents to check out and build LLVM, Clang and Clang Extra Tools with CMake.
-
-Once you are done, change to the ``llvm/tools/clang/tools/extra`` directory, and
-let's start!

-.. _Using Clang Tools: http://clang.llvm.org/docs/ClangTools.html

-
-The Directory Structure
------------------------
-

-``llvm/tools/clang/tools/extra`` directory and is structured as follows:
-
-::
-
- clang-tidy/ # Clang-tidy core.
- |-- ClangTidy.h # Interfaces for users and checks.
- |-- ClangTidyModule.h # Interface for clang-tidy modules.

-
-
-Writing a clang-tidy Check
---------------------------
-
-So you have an idea of a useful check for :program:`clang-tidy`.
-
-First, if you're not familiar with LLVM development, read through the `Getting
-Started with LLVM`_ document for instructions on setting up your workflow and
-the `LLVM Coding Standards`_ document to familiarize yourself with the coding
-style used in the project. For code reviews we mostly use `LLVM Phabricator`_.
-
-.. _Getting Started with LLVM: http://llvm.org/docs/GettingStarted.html
-.. _LLVM Coding Standards: http://llvm.org/docs/CodingStandards.html
-.. _LLVM Phabricator: http://llvm.org/docs/Phabricator.html
-
-Next, you need to decide which module the check belongs to. Modules
-are located in subdirectories of `clang-tidy/
-<http://reviews.llvm.org/diffusion/L/browse/clang-tools-extra/trunk/clang-tidy/>`_
-and contain checks targeting a certain aspect of code quality (performance,
-readability, etc.), certain coding style or standard (Google, LLVM, CERT, etc.)
-or a widely used API (e.g. MPI). Their names are same as user-facing check
-groups names described :ref:`above <checks-groups-table>`.
-
-After choosing the module and the name for the check, run the
-``clang-tidy/add_new_check.py`` script to create the skeleton of the check and
-plug it to :program:`clang-tidy`. It's the recommended way of adding new checks.
-
-If we want to create a `readability-awesome-function-names`, we would run:
-
-.. code-block:: console
-
- $ clang-tidy/add_new_check.py readability awesome-function-names
-
-
-The ``add_new_check.py`` script will:
- * create the class for your check inside the specified module's directory and
- register it in the module and in the build system;
- * create a lit test file in the ``test/clang-tidy/`` directory;
- * create a documentation file and include it into the
- ``docs/clang-tidy/checks/list.rst``.
-
-Let's see in more detail at the check class definition:
-
-.. code-block:: c++
-
- ...
-
- #include "../ClangTidy.h"
-
- namespace clang {
- namespace tidy {
- namespace readability {
-
- ...
- class AwesomeFunctionNamesCheck : public ClangTidyCheck {
- public:
- AwesomeFunctionNamesCheck(StringRef Name, ClangTidyContext *Context)
- : ClangTidyCheck(Name, Context) {}
- void registerMatchers(ast_matchers::MatchFinder *Finder) override;
- void check(const ast_matchers::MatchFinder::MatchResult &Result) override;
- };
-
- } // namespace readability
- } // namespace tidy
- } // namespace clang
-
- ...
-
-Constructor of the check receives the ``Name`` and ``Context`` parameters, and
-must forward them to the ``ClangTidyCheck`` constructor.
-
-In our case the check needs to operate on the AST level and it overrides the
-``registerMatchers`` and ``check`` methods. If we wanted to analyze code on the
-preprocessor level, we'd need instead to override the ``registerPPCallbacks``
-method.
-
-In the ``registerMatchers`` method we create an AST Matcher (see `AST Matchers`_
-for more information) that will find the pattern in the AST that we want to
-inspect. The results of the matching are passed to the ``check`` method, which
-can further inspect them and report diagnostics.
-
-.. code-block:: c++
-
- using namespace ast_matchers;
-
- void AwesomeFunctionNamesCheck::registerMatchers(MatchFinder *Finder) {
- Finder->addMatcher(functionDecl().bind("x"), this);
- }
-
- void AwesomeFunctionNamesCheck::check(const MatchFinder::MatchResult &Result) {
- const auto *MatchedDecl = Result.Nodes.getNodeAs<FunctionDecl>("x");
- if (MatchedDecl->getName().startswith("awesome_"))
- return;
- diag(MatchedDecl->getLocation(), "function %0 is insufficiently awesome")
- << MatchedDecl
- << FixItHint::CreateInsertion(MatchedDecl->getLocation(), "awesome_");
- }
-
-(If you want to see an example of a useful check, look at
-`clang-tidy/google/ExplicitConstructorCheck.h
-<http://reviews.llvm.org/diffusion/L/browse/clang-tools-extra/trunk/clang-tidy/google/ExplicitConstructorCheck.h>`_
-and `clang-tidy/google/ExplicitConstructorCheck.cpp
-<http://reviews.llvm.org/diffusion/L/browse/clang-tools-extra/trunk/clang-tidy/google/ExplicitConstructorCheck.cpp>`_).
-
-
-Registering your Check
-----------------------
-
-(The ``add_new_check.py`` takes care of registering the check in an existing
-module. If you want to create a new module or know the details, read on.)
-
-The check should be registered in the corresponding module with a distinct name:
-
-.. code-block:: c++
-
- class MyModule : public ClangTidyModule {
- public:
- void addCheckFactories(ClangTidyCheckFactories &CheckFactories) override {
- CheckFactories.registerCheck<ExplicitConstructorCheck>(
- "my-explicit-constructor");
- }
- };
-
-Now we need to register the module in the ``ClangTidyModuleRegistry`` using a
-statically initialized variable:
-
-.. code-block:: c++
-
- static ClangTidyModuleRegistry::Add<MyModule> X("my-module",
- "Adds my lint checks.");
-
-
-When using LLVM build system, we need to use the following hack to ensure the
-module is linked into the :program:`clang-tidy` binary:
-
-Add this near the ``ClangTidyModuleRegistry::Add<MyModule>`` variable:
-
-.. code-block:: c++
-
- // This anchor is used to force the linker to link in the generated object file
- // and thus register the MyModule.
- volatile int MyModuleAnchorSource = 0;
-
-And this to the main translation unit of the :program:`clang-tidy` binary (or
-the binary you link the ``clang-tidy`` library in)
-``clang-tidy/tool/ClangTidyMain.cpp``:
-
-.. code-block:: c++
-
- // This anchor is used to force the linker to link the MyModule.
- extern volatile int MyModuleAnchorSource;
- static int MyModuleAnchorDestination = MyModuleAnchorSource;
-
-
-Configuring Checks
-------------------
-
-If a check needs configuration options, it can access check-specific options
-using the ``Options.get<Type>("SomeOption", DefaultValue)`` call in the check
-constructor. In this case the check should also override the
-``ClangTidyCheck::storeOptions`` method to make the options provided by the
-check discoverable. This method lets :program:`clang-tidy` know which options
-the check implements and what the current values are (e.g. for the
-``-dump-config`` command line option).
-
-.. code-block:: c++
-
- class MyCheck : public ClangTidyCheck {
- const unsigned SomeOption1;
- const std::string SomeOption2;
-
- public:
- MyCheck(StringRef Name, ClangTidyContext *Context)
- : ClangTidyCheck(Name, Context),
- SomeOption(Options.get("SomeOption1", -1U)),
- SomeOption(Options.get("SomeOption2", "some default")) {}
-
- void storeOptions(ClangTidyOptions::OptionMap &Opts) override {
- Options.store(Opts, "SomeOption1", SomeOption1);
- Options.store(Opts, "SomeOption2", SomeOption2);
- }
- ...
-
-Assuming the check is registered with the name "my-check", the option can then
-be set in a ``.clang-tidy`` file in the following way:
-
-.. code-block:: yaml
-
- CheckOptions:
- - key: my-check.SomeOption1
- value: 123
- - key: my-check.SomeOption2
- value: 'some other value'
-
-If you need to specify check options on a command line, you can use the inline
-YAML format:
-
-.. code-block:: console
-
- $ clang-tidy -config="{CheckOptions: [{key: a, value: b}, {key: x, value: y}]}" ...
-
-
-Testing Checks
---------------
-
-To run tests for :program:`clang-tidy` use the command:
-
-.. code-block:: console
-
- $ ninja check-clang-tools
-
-:program:`clang-tidy` checks can be tested using either unit tests or
-`lit`_ tests. Unit tests may be more convenient to test complex replacements
-with strict checks. `Lit`_ tests allow using partial text matching and regular
-expressions which makes them more suitable for writing compact tests for
-diagnostic messages.
-
-The ``check_clang_tidy.py`` script provides an easy way to test both
-diagnostic messages and fix-its. It filters out ``CHECK`` lines from the test
-file, runs :program:`clang-tidy` and verifies messages and fixes with two
-separate `FileCheck`_ invocations: once with FileCheck's directive
-prefix set to ``CHECK-MESSAGES``, validating the diagnostic messages,
-and once with the directive prefix set to ``CHECK-FIXES``, running
-against the fixed code (i.e., the code after generated fix-its are
-applied). In particular, ``CHECK-FIXES:`` can be used to check
-that code was not modified by fix-its, by checking that it is present
-unchanged in the fixed code. The full set of `FileCheck`_ directives
-is available (e.g., ``CHECK-MESSAGES-SAME:``, ``CHECK-MESSAGES-NOT:``), though
-typically the basic ``CHECK`` forms (``CHECK-MESSAGES`` and ``CHECK-FIXES``)
-are sufficient for clang-tidy tests. Note that the `FileCheck`_
-documentation mostly assumes the default prefix (``CHECK``), and hence
-describes the directive as ``CHECK:``, ``CHECK-SAME:``, ``CHECK-NOT:``, etc.
-Replace ``CHECK`` by either ``CHECK-FIXES`` or ``CHECK-MESSAGES`` for
-clang-tidy tests.
-
-An additional check enabled by ``check_clang_tidy.py`` ensures that
-if `CHECK-MESSAGES:` is used in a file then every warning or error
-must have an associated CHECK in that file. Or, you can use ``CHECK-NOTES:``
-instead, if you want to **also** ensure that all the notes are checked.
-
-To use the ``check_clang_tidy.py`` script, put a .cpp file with the
-appropriate ``RUN`` line in the ``test/clang-tidy`` directory. Use
-``CHECK-MESSAGES:`` and ``CHECK-FIXES:`` lines to write checks against
-diagnostic messages and fixed code.
-
-It's advised to make the checks as specific as possible to avoid checks matching
-to incorrect parts of the input. Use ``[[@LINE+X]]``/``[[@LINE-X]]``
-substitutions and distinct function and variable names in the test code.
-
-Here's an example of a test using the ``check_clang_tidy.py`` script (the full
-source code is at `test/clang-tidy/google-readability-casting.cpp`_):
-
-.. code-block:: c++
-
- // RUN: %check_clang_tidy %s google-readability-casting %t
-
- void f(int a) {
- int b = (int)a;
- // CHECK-MESSAGES: :[[@LINE-1]]:11: warning: redundant cast to the same type [google-readability-casting]
- // CHECK-FIXES: int b = a;
- }
-
-To check more than one scenario in the same test file use
-``-check-suffix=SUFFIX-NAME`` on ``check_clang_tidy.py`` command line or
-``-check-suffixes=SUFFIX-NAME-1,SUFFIX-NAME-2,...``.
-With ``-check-suffix[es]=SUFFIX-NAME`` you need to replace your ``CHECK-*``
-directives with ``CHECK-MESSAGES-SUFFIX-NAME`` and ``CHECK-FIXES-SUFFIX-NAME``.
-
-Here's an example:
-
-.. code-block:: c++
-
- // RUN: %check_clang_tidy -check-suffix=USING-A %s misc-unused-using-decls %t -- -- -DUSING_A
- // RUN: %check_clang_tidy -check-suffix=USING-B %s misc-unused-using-decls %t -- -- -DUSING_B
- // RUN: %check_clang_tidy %s misc-unused-using-decls %t
- ...
- // CHECK-MESSAGES-USING-A: :[[@LINE-8]]:10: warning: using decl 'A' {{.*}}
- // CHECK-MESSAGES-USING-B: :[[@LINE-7]]:10: warning: using decl 'B' {{.*}}
- // CHECK-MESSAGES: :[[@LINE-6]]:10: warning: using decl 'C' {{.*}}
- // CHECK-FIXES-USING-A-NOT: using a::A;$
- // CHECK-FIXES-USING-B-NOT: using a::B;$
- // CHECK-FIXES-NOT: using a::C;$
-
-
-There are many dark corners in the C++ language, and it may be difficult to make
-your check work perfectly in all cases, especially if it issues fix-it hints. The
-most frequent pitfalls are macros and templates:
-
-1. code written in a macro body/template definition may have a different meaning
- depending on the macro expansion/template instantiation;
-2. multiple macro expansions/template instantiations may result in the same code
- being inspected by the check multiple times (possibly, with different
- meanings, see 1), and the same warning (or a slightly different one) may be
- issued by the check multiple times; :program:`clang-tidy` will deduplicate
- _identical_ warnings, but if the warnings are slightly different, all of them
- will be shown to the user (and used for applying fixes, if any);
-3. making replacements to a macro body/template definition may be fine for some
- macro expansions/template instantiations, but easily break some other
- expansions/instantiations.

-
-
-Running clang-tidy on LLVM
---------------------------
-
-To test a check it's best to try it out on a larger code base. LLVM and Clang
-are the natural targets as you already have the source code around. The most
-convenient way to run :program:`clang-tidy` is with a compile command database;
-CMake can automatically generate one, for a description of how to enable it see
-`How To Setup Tooling For LLVM`_. Once ``compile_commands.json`` is in place and
-a working version of :program:`clang-tidy` is in ``PATH`` the entire code base
-can be analyzed with ``clang-tidy/tool/run-clang-tidy.py``. The script executes
-:program:`clang-tidy` with the default set of checks on every translation unit
-in the compile command database and displays the resulting warnings and errors.
-The script provides multiple configuration flags.
-
-* The default set of checks can be overridden using the ``-checks`` argument,
- taking the identical format as :program:`clang-tidy` does. For example
- ``-checks=-*,modernize-use-override`` will run the ``modernize-use-override``
- check only.
-
-* To restrict the files examined you can provide one or more regex arguments
- that the file names are matched against.
- ``run-clang-tidy.py clang-tidy/.*Check\.cpp`` will only analyze clang-tidy
- checks. It may also be necessary to restrict the header files warnings are
- displayed from using the ``-header-filter`` flag. It has the same behavior
- as the corresponding :program:`clang-tidy` flag.
-
-* To apply suggested fixes ``-fix`` can be passed as an argument. This gathers
- all changes in a temporary directory and applies them. Passing ``-format``
- will run clang-format over changed lines.
-
-
-On checks profiling
--------------------
-
-:program:`clang-tidy` can collect per-check profiling info, and output it
-for each processed source file (translation unit).
-
-To enable profiling info collection, use the ``-enable-check-profile`` argument.
-The timings will be output to ``stderr`` as a table. Example output:
-
-.. code-block:: console
-
- $ clang-tidy -enable-check-profile -checks=-*,readability-function-size source.cpp
- ===-------------------------------------------------------------------------===
- clang-tidy checks profiling
- ===-------------------------------------------------------------------------===
- Total Execution Time: 1.0282 seconds (1.0258 wall clock)
-
- ---User Time--- --System Time-- --User+System-- ---Wall Time--- --- Name ---
- 0.9136 (100.0%) 0.1146 (100.0%) 1.0282 (100.0%) 1.0258 (100.0%) readability-function-size
- 0.9136 (100.0%) 0.1146 (100.0%) 1.0282 (100.0%) 1.0258 (100.0%) Total
-
-It can also store that data as JSON files for further processing. Example output:
-
-.. code-block:: console
-
- $ clang-tidy -enable-check-profile -store-check-profile=. -checks=-*,readability-function-size source.cpp
- $ # Note that there won't be timings table printed to the console.
- $ ls /tmp/out/
- 20180516161318717446360-source.cpp.json
- $ cat 20180516161318717446360-source.cpp.json
- {
- "file": "/path/to/source.cpp",
- "timestamp": "2018-05-16 16:13:18.717446360",
- "profile": {
- "time.clang-tidy.readability-function-size.wall": 1.0421266555786133e+00,
- "time.clang-tidy.readability-function-size.user": 9.2088400000005421e-01,
- "time.clang-tidy.readability-function-size.sys": 1.2418899999999974e-01
- }
- }
-
-There is only one argument that controls profile storage:
-
-* ``-store-check-profile=<prefix>``
-
- By default reports are printed in tabulated format to stderr. When this option
- is passed, these per-TU profiles are instead stored as JSON.
- If the prefix is not an absolute path, it is considered to be relative to the
- directory from where you have run :program:`clang-tidy`. All ``.`` and ``..``
- patterns in the path are collapsed, and symlinks are resolved.
-
- Example:
- Let's suppose you have a source file named ``example.cpp``, located in the
- ``/source`` directory. Only the input filename is used, not the full path
- to the source file. Additionally, it is prefixed with the current timestamp.
-
- * If you specify ``-store-check-profile=/tmp``, then the profile will be saved
- to ``/tmp/<ISO8601-like timestamp>-example.cpp.json``
-
- * If you run :program:`clang-tidy` from within ``/foo`` directory, and specify
- ``-store-check-profile=.``, then the profile will still be saved to
- ``/foo/<ISO8601-like timestamp>-example.cpp.json``

-
-:program:`Clangd` is an implementation of the `Language Server Protocol
-<https://github.com/Microsoft/language-server-protocol>`_ leveraging Clang.
-Clangd's goal is to provide language "smartness" features like code completion,
-find references, etc. for clients such as C/C++ Editors.
-
-Using Clangd
-==================
-
-:program:`Clangd` is not meant to be used by C/C++ developers directly but
-rather from a client implementing the protocol. A client would be typically
-implemented in an IDE or an editor.
-
-At the moment, `Visual Studio Code <https://code.visualstudio.com/>`_ is mainly
-used in order to test :program:`Clangd` but more clients are likely to make
-use of :program:`Clangd` in the future as it matures and becomes a production
-quality tool. If you are interested in trying :program:`Clangd` in combination
-with Visual Studio Code, you can start by `installing Clangd`_ or
-`building Clangd`_, then open Visual Studio Code in the clangd-vscode folder and
-launch the extension.
-
-Installing Clangd
-==================
-
-Packages are available for debian-based distributions, see the `LLVM packages
-page <http://apt.llvm.org/>`_. :program:`Clangd` is included in the
-`clang-tools` package.
-However, it is a good idea to check your distribution's packaging system first
-as it might already be available.
-
-Otherwise, you can install :program:`Clangd` by `building Clangd`_ first.
-
-Building Clangd
-==================
-
-You can follow the instructions for `building Clang
-<https://clang.llvm.org/get_started.html>`_ but "extra Clang tools" is **not**
-optional.
-
-Current Status
-==================
-
-Many features could be implemented in :program:`Clangd`.
-Here is a list of features that could be useful with the status of whether or
-not they are already implemented in :program:`Clangd` and specified in the
-Language Server Protocol. Note that for some of the features, it is not clear
-whether or not they should be part of the Language Server Protocol, so those
-features might be eventually developed outside :program:`Clangd` or as an
-extension to the protocol.

-Editor Integration
-==================
-
-Any full-featured Language Server Protocol Client implementation should work
-with :program:`Clangd`. This `list
-<https://langserver.org/#implementations-client>`_ contains information about
-extensions and plugins that are known to work for different editors.
-
-Vim Integration
----------------
-
-LanguageClient-neovim
-~~~~~~~~~~~~~~~~~~~~~
-
-One of the options of using :program:`Clangd` in :program:`vim` (or
-:program:`nvim`) is to utilize `LanguageClient-neovim
-<https://github.com/autozimu/LanguageClient-neovim>`_ plugin. Please see the
-`Clangd Wiki page
-<https://github.com/autozimu/LanguageClient-neovim/wiki/Clangd>`_ for
-instructions.
-
-VSCode Integration
-------------------
-
-:program:`VSCode` provides `vscode-clangd
-<https://marketplace.visualstudio.com/items?itemName=llvm-vs-code-extensions.vscode-clangd>`_
-which is published in Visual Studio Marketplace and can be installed direcetly
-from :program:`VSCode`.
-
-Emacs Integration
------------------
-
-:program:`Emacs` provides `lsp-mode <github.com/emacs-lsp/lsp-mode>`_ and
-`Eglot <https://github.com/joaotavora/eglot>`_ plugins for LSP integration.
-
-Getting Involved
-==================
-
-A good place for interested contributors is the `Clangd developer mailing list
-<http://lists.llvm.org/mailman/listinfo/clangd-dev>`_. For discussions with the
-broader community on topics not only related to Clangd, use
-`Clang developer mailing list
-<http://lists.llvm.org/mailman/listinfo/cfe-dev>`_.
-If you're also interested in contributing patches to :program:`Clangd`, take a
-look at the `LLVM Developer Policy
-<http://llvm.org/docs/DeveloperPolicy.html>`_ and `Code Reviews
-<http://llvm.org/docs/Phabricator.html>`_ page. Contributions of new features
-to the `Language Server Protocol
-<https://github.com/Microsoft/language-server-protocol>`_ itself would also be
-very useful, so that :program:`Clangd` can eventually implement them in a
-conforming way.
+All :program:`clangd` documentation was moved to the :doc:`clangd/index` pages.

+===================
+Protocol extensions
+===================
+
+.. contents::
+
+clangd supports some features that are not in the official
+`Language Server Protocol specification
+<https://microsoft.github.io/language-server-protocol/specification>`__.
+
+We cautious about adding extensions. The most important considerations are:
+
+- **Editor support**: How many users will the feature be available to?
+- **Standardization**: Is the feature stable? Is it likely to be adopted by more
+ editors over time?
+- **Utility**: Does the feature provide a lot of value?
+- **Complexity**: Is this hard to implement in clangd, or constrain future work?
+ Is the protocol complicated?
+
+These extensions may evolve or disappear over time. If you use them, try to
+recover gracefully if the structures aren't what's expected.
+
+Switch between the implementation file and the header
+=====================================================
+
+*This extension is supported in clangd 6 and newer.*
+
+Switching between the implementation file and the header is an important
+feature for C++. A language server that understands C++ can do a better job
+than the editor.
+
+**New client->server request**: ``textDocument/switchSourceHeader``.
+
+Lets editors switch between the main source file (``*.cpp``) and header (``*.h``).
+
+Parameter: ``TextDocumentIdentifier``: an open file.
+
+Result: ``string``: the URI of the corresponding header (if a source file was
+provided) or source file (if a header was provided).
+
+If the corresponding file can't be determined, ``""`` is returned.
+
+File status
+===========
+
+*This extension is supported in clangd 8 and newer.*
+
+It is important to provide feedback to the user when the UI is not responsive.
+
+This extension provides information about activity on clangd's per-file worker
+thread. This information can be displayed to users to let them know that the
+language server is busy with something. For example, in clangd, building the
+AST blocks many other operations.
+
+**New server->client notification**: ``textDocument/clangd.fileStatus``
+
+Sent when the current activity for a file changes. Replaces previous activity
+for that file.
+
+Parameter: ``FileStatus`` object with properties:
+
+- ``uri : string``: the document whose status is being updated.
+- ``state : string``: human-readable information about current activity.
+
+**New initialization option**: ``initializationOptions.clangdFileStatus : bool``
+
+Enables receiving ``textDocument/clangd.fileStatus`` notifications.
+
+Compilation commands
+====================
+
+*This extension is supported in clangd 8 and newer.*
+
+clangd relies on knowing accurate compilation options to correctly interpret a
+file. Typically they are found in a ``compile_commands.json`` file in a
+directory that contains the file, or an ancestor directory. The following
+extensions allow editors to supply the commands over LSP instead.
+
+**New initialization option**: ``initializationOptions.compilationDatabasePath : string``
+
+Specifies the directory containing the compilation database (e.g.,
+``compile_commands.json``). This path will be used for all files, instead of
+searching their ancestor directories.
+
+**New initialization option**: ``initializationOptions.fallbackFlags : string[]``
+
+Controls the flags used when no specific compile command is found. The compile
+command will be approximately ``clang $FILE $fallbackFlags`` in this case.
+
+**New configuration setting**: ``settings.compilationDatabaseChanges : {string: CompileCommand}``
+
+Provides compile commands for files. This can also be provided on startup as
+``initializationOptions.compilationDatabaseChanges``.
+
+Keys are file paths (Not URIs!)
+
+Values are ``{workingDirectory: string, compilationCommand: string[]}``.
+
+Force diagnostics generation
+============================
+
+*This extension is supported in clangd 7 and newer.*
+
+Clangd does not regenerate diagnostics for every version of a file (e.g., after
+every keystroke), as that would be too slow. Its heuristics ensure:
+
+- diagnostics do not get too stale,
+- if you stop editing, diagnostics will catch up.
+
+This extension allows editors to force diagnostics to be generated or not
+generated at a particular revision.
+
+**New property of** ``textDocument/didChange`` **request**: ``wantDiagnostics : bool``
+
+- if true, diagnostics will be produced for exactly this version.
+- if false, diagnostics will not be produced for this version, even if there
+ are no further edits.
+- if unset, diagnostics will be produced for this version or some subsequent
+ one in a bounded amount of time.
+
+Diagnostic categories
+=====================
+
+*This extension is supported in clangd 8 and newer.*
+
+Clang compiler groups diagnostics into categories (e.g., "Inline Assembly
+Issue"). Clangd can emit these categories for interested editors.
+
+**New property of** ``Diagnostic`` **object**: ``category : string``:
+
+A human-readable name for a group of related diagnostics. Diagnostics with the
+same code will always have the same category.
+
+**New client capability**: ``textDocument.publishDiagnostics.categorySupport``:
+
+Requests that clangd send ``Diagnostic.category``.
+
+Inline fixes for diagnostics
+============================
+
+*This extension is supported in clangd 8 and newer.*
+
+LSP specifies that code actions for diagnostics (fixes) are retrieved
+asynchronously using ``textDocument/codeAction``. clangd always computes fixes
+eagerly. Providing them alongside diagnostics can improve the UX in editors.
+
+**New property of** ``Diagnostic`` **object**: ``codeActions : CodeAction[]``:
+
+All the code actions that address this diagnostic.
+
+**New client capability**: ``textDocument.publishDiagnostics.codeActionsInline : bool``
+
+Requests clangd to send ``Diagnostic.codeActions``.
+
+Symbol info request
+===================
+
+*This extension is supported in clangd 8 and newer.*
+
+**New client->server request**: ``textDocument/symbolInfo``:
+
+This request attempts to resolve the symbol under the cursor, without
+retrieving further information (like definition location, which may require
+consulting an index). This request was added to support integration with
+indexes outside clangd.
+
+Parameter: ``TextDocumentPositionParams``
+
+Response: ``SymbolDetails``, an object with properties:
+
+- ``name : string`` the unqualified name of the symbol
+- ``containerName : string`` the enclosing namespace, class etc (without
+ trailing ``::``)
+- ``usr : string``: the clang-specific "unified symbol resolution" identifier
+- ``id : string?``: the clangd-specific opaque symbol ID

+
+clangd respects your project's ``.clang-tidy`` file which controls the checks
+to run. Not all checks work within clangd. You must pass the ``-clang-tidy``
+flag to enable this feature.
+
+Code completion
+===============
+
+You'll see suggestions as you type based on what methods, variables, etc are
+available in this context.

+
+Abbreviating words may help you find the right result faster. If you type in
+``camelCase`` but the function you're looking for is ``snake_case``, that's OK.
+
+Insertion of namespace qualifiers and includes
+----------------------------------------------
+
+**(New in v8)**
+clangd will sometimes suggest results from other files and namespaces. In this
+case the correct qualifier and ``#include`` directive will be inserted.

+
+Signature help
+--------------
+
+Some editors will show you the parameters of the function you're calling, as
+you fill them in.

+
+Cross-references
+================
+
+The following features let you navigate your codebase.
+
+If there is no project-wide index, cross-references work across the files
+you have opened.
+
+**(New in v9)**
+clangd will also automatically index your whole project.
+
+Find definition/declaration
+---------------------------
+
+Jump to the definition or declaration of a symbol under the cursor.
+
+:raw-html:`<details><summary markdown="span">Animated demo</summary>`
+
+.. image:: GoToDefinitionInVSCode.gif
+ :align: center
+ :alt: Demonstration of the "Go to definition" feature
+
+:raw-html:`</details>`
+
+**(New in v9)**
+Some editors only expose "find definition"; use "find definition" on the
+definition to jump to the declaration.
+
+"Find definition" also works on ``#include`` lines, to jump to the included
+file.
+
+Find references
+---------------
+
+Show all references to a symbol under the cursor.
+
+:raw-html:`<details><summary markdown="span">Animated demo</summary>`
+
+.. image:: FindAllReferencesInVSCode.gif
+ :align: center
+ :alt: Demonstration of the "Find all references" feature
+
+:raw-html:`</details>`
+
+Some editors will automatically highlight local references to the selected
+symbol as you move around a file.
+
+Navigation
+==========
+
+clangd informs the editor of the code structure in the current file.
+Some editors use this to present an outline view:
+
+:raw-html:`<details><summary markdown="span">Screenshot</summary>`
+
+.. image:: OutlineInVSCode.png
+ :align: center
+ :alt: Outline of a file
+
+:raw-html:`</details>`
+
+In VSCode, the outline is also presented as breadcrumbs that allow jumping to a
+symbol within the current file. Searching for symbols within the scope of the
+whole project is also possible.
+
+:raw-html:`<details><summary markdown="span">Animated demo</summary>`
+
+.. image:: NavigationWithBreadcrumbsInVSCode.gif
+ :align: center
+ :alt: Navigation with breadcrumbs
+
+:raw-html:`</details>`
+
+Formatting
+==========
+
+clangd embeds `clang-format <https://clang.llvm.org/docs/ClangFormat.html>`__,
+which can reformat your code: fixing indentation, breaking lines, and reflowing
+comments.
+
+:raw-html:`<details><summary markdown="span">Animated demo</summary>`
+
+.. image:: FormatSelectionInVSCode.gif
+ :align: center
+ :alt: Formatting selected code
+
+:raw-html:`</details>`
+
+clangd respects your project's ``.clang-format`` file which controls styling
+options.
+
+Format-as-you-type is experimental and doesn't work well yet.
+
+Complete list of features
+=========================
+
+Here is a list of features that could be useful for editors, together with the
+implementation status in clangd, and specification in the Language Server
+Protocol.
+
+It is not clear whether or not some of the features mentioned below should be a
+part of the Language Server Protocol; those features might be eventually
+developed outside clangd or become clangd extensions to LSP.

+===========================
+Getting started with clangd
+===========================
+
+.. contents::
+
+.. role:: raw-html(raw)
+ :format: html
+
+To use clangd, you need to:
+
+- install clangd,
+- install a plugin for your editor,
+- tell clangd how your project is built.
+
+Installing clangd
+=================
+
+You need a **recent** version of clangd: 7.0 was the first usable release, and
+8.0 is much better.
+
+After installing, ``clangd --version`` should print ``clangd version 7.0.0`` or
+later.
+
+:raw-html:`<details><summary markdown="span">macOS</summary>`
+
+`Homebrew <https://brew.sh>`__ can install clangd along with LLVM:
+
+.. code-block:: console
+
+ $ brew install llvm
+
+If you don't want to use Homebrew, you can download the a binary release of
+LLVM from `releases.llvm.org <http://releases.llvm.org/download.html>`__.
+Alongside ``bin/clangd`` you will need at least ``lib/clang/*/include``:
+
+.. code-block:: console
+
+ $ cp clang+llvm-7.0.0/bin/clangd /usr/local/bin/clangd
+ $ cp -r clang+llvm-7.0.0/lib/clang/ /usr/local/lib/
+
+:raw-html:`</details>`
+
+:raw-html:`<details><summary markdown="span">Windows</summary>`
+
+Download and run the LLVM installer from `releases.llvm.org
+<http://releases.llvm.org/download.html>`__.
+
+:raw-html:`</details>`
+
+:raw-html:`<details><summary markdown="span">Debian/Ubuntu</summary>`
+
+The ``clang-tools`` package usually contains an old version of clangd.
+
+Try to install the latest release (8.0):
+
+.. code-block:: console
+
+ $ sudo apt-get install clang-tools-8
+
+If that is not found, at least ``clang-tools-7`` should be available.
+
+The ``clangd`` executable will be installed as ``/usr/bin/clangd-8``. Make it
+the default ``clangd``:
+
+.. code-block:: console
+
+ $ sudo update-alternatives --install /usr/bin/clangd clangd /usr/bin/clangd-8 100
+
+:raw-html:`</details>`
+
+:raw-html:`<details><summary markdown="span">Other systems</summary>`
+
+Most distributions include clangd in a ``clang-tools`` package, or in the full
+``llvm`` distribution.
+
+For some platforms, binaries are also avaliable at `releases.llvm.org
+<http://releases.llvm.org/download.html>`__.
+
+:raw-html:`</details>`
+
+Editor plugins
+==============
+
+Language Server plugins are available for many editors. In principle, clangd
+should work with any of them, though the feature set and UI may vary.
+
+Here are some plugins we know work well with clangd.
+
+:raw-html:`<details><summary markdown="span">YouCompleteMe for Vim</summary>`
+
+`YouCompleteMe <https://valloric.github.io/YouCompleteMe/>`__ supports clangd.
+However, clangd support is not turned on by default, so you must install
+YouCompleteMe with ``install.py --clangd-completer``.
+
+We recommend changing a couple of YCM's default settings. In ``.vimrc`` add:
+
+::
+
+ " Let clangd fully control code completion
+ let g:ycm_clangd_uses_ycmd_caching = 0
+ " Use installed clangd, not YCM-bundled clangd which doesn't get updates.
+ let g:ycm_clangd_binary_path = exepath("clangd")
+
+You should see errors highlighted and code completions as you type.
+
+.. image:: CodeCompletionInYCM.png
+ :align: center
+ :alt: Code completion in YouCompleteMe
+
+YouCompleteMe supports many of clangd's features:
+
+- code completion,
+- diagnostics and fixes (``:YcmCompleter FixIt``),
+- find declarations, references, and definitions (``:YcmCompleter GoTo`` etc),
+- rename symbol (``:YcmCompleter RefactorRename``).
+
+**Under the hood**
+
+- **Debug logs**: run ``:YcmDebugInfo`` to see clangd status, and ``:YcmToggleLogs``
+ to view clangd's debug logs.
+- **Command-line flags**: Set ``g:ycm_clangd_args`` in ``.vimrc``, e.g.:
+
+ ::
+
+ let g:ycm_clangd_args = ['-log=verbose', '-pretty']
+
+- **Alternate clangd binary**: set ``g:ycm_clangd_binary_path`` in ``.vimrc``.
+
+:raw-html:`</details>`
+
+:raw-html:`<details><summary markdown="span">LanguageClient for Vim and Neovim</summary>`
+
+`LanguageClient-neovim <https://github.com/autozimu/LanguageClient-neovim>`__
+has `instructions for using clangd
+<https://github.com/autozimu/LanguageClient-neovim/wiki/Clangd>`__, and **may**
+be easier to install than YouCompleteMe.
+
+:raw-html:`</details>`
+
+:raw-html:`<details><summary markdown="span">Eglot for Emacs</summary>`
+
+`eglot <https://github.com/joaotavora/eglot>`__ can be configured to work with
+clangd.
+
+Install eglot with ``M-x package-install RET eglot RET``.
+
+Add the following to ``~/.emacs`` to enable clangd:
+
+::
+
+ (require 'eglot)
+ (add-to-list 'eglot-server-programs '((c++-mode c-mode) "clangd"))
+ (add-hook 'c-mode-hook 'eglot-ensure)
+ (add-hook 'c++-mode-hook 'eglot-ensure)
+
+After restarting you should see diagnostics for errors in your code, and ``M-x
+completion-at-point`` should work.
+
+.. image:: DiagnosticsInEmacsEglot.png
+ :align: center
+ :alt: Diagnostics in Emacs
+
+eglot supports many of clangd's features, with caveats:
+
+- code completion, though the interaction is quite poor (even with
+ ``company-mode``, see below),
+- diagnostics and fixes,
+- find definitions and references (``M-x xref-find-definitions`` etc),
+- hover and highlights,
+- code actions (``M-x eglot-code-actions``).
+
+**company-mode**
+
+eglot does have basic integration with company-mode, which provides a more
+fluent completion UI.
+
+You can install it with ``M-x package-install RET company RET``, and enable it
+with ``M-x company-mode``.
+
+**company-clang is enabled by default**, and will interfere with clangd.
+Disable it in ``M-x customize-variable RET company-backends RET``.
+
+Completion still has some major limitations:
+
+- completions are alphabetically sorted, not ranked.
+- only pure-prefix completions are shown - no fuzzy matches.
+- completion triggering seems to be a bit hit-and-miss.
+
+.. image:: CodeCompletionInEmacsCompanyMode.png
+ :align: center
+ :alt: Completion in company-mode
+
+**Under the hood**
+
+- **Debug logs**: available in the ``EGLOT stderr`` buffer.
+- **Command-line flags and alternate binary**: instead of adding ``"clangd"``
+ to ``eglot-server-programs``, add ``("/path/to/clangd" "-log=verbose")`` etc.

+
+The official extension is `vscode-clangd
+<https://marketplace.visualstudio.com/items?itemName=llvm-vs-code-extensions.vscode-clangd>`__
+and can be installed from within VSCode.
+
+Choose **View** --> **Extensions**, then search for "clangd". (Make sure the
+Microsoft C/C++ extension is **not** installed).
+
+After restarting, you should see red underlines underneath errors, and you

+- find symbol in file (``Ctrl-P @foo``) or workspace (``Ctrl-P #foo``)
+- hover and highlights
+- code actions
+
+**Under the hood**
+
+- **Debug logs**: when clangd is running, you should see "Clang Language

+- diagnostics and fixes
+- find definition and references
+- hover and highlights
+- code actions
+
+**Under the hood**
+

+**LSP**.
+
+- **Debug logs**: add ``"log_stderr": true``
+- **Command-line flags and alternate clangd binary**: inside the ``"clients":

+ "-log=verbose"]`` etc.
+
+:raw-html:`</details>`
+
+:raw-html:`<details><summary markdown="span">Other editors</summary>`
+
+There is a directory of LSP clients at `langserver.org
+<http://langserver.org>`__.
+
+A generic client should be configured to run the command ``clangd``, and
+communicate via the language server protocol on standard input/output.
+
+If you don't have strong feelings about an editor, we suggest you try out
+`VSCode <https://code.visualstudio.com/>`__, it has excellent language server
+support and most faithfully demonstrates what clangd can do.
+
+:raw-html:`</details>`
+
+Project setup
+=============
+
+To understand source code in your project, clangd needs to know the build
+flags. (This is just a fact of life in C++, source files are not
+self-contained.)
+
+By default, clangd will assume that source code is built as ``clang
+some_file.cc``, and you'll probably get spurious errors about missing
+``#include``\ d files, etc. There are a couple of ways to fix this.
+
+``compile_commands.json``
+-------------------------
+
+``compile_commands.json`` file provides compile commands for all source files
+in the project. This file is usually generated by the build system, or tools
+integrated with the build system. Clangd will look for this file in the parent
+directories of the files you edit.
+
+:raw-html:`<details><summary markdown="span">CMake-based projects</summary>`
+
+If your project builds with CMake, it can generate ``compile_commands.json``.
+You should enable it with:
+
+::
+
+ $ cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=1
+
+``compile_commands.json`` will be written to your build directory. You should
+symlink it (or copy it) to the root of your source tree, if they are different.
+
+::
+
+ $ ln -s ~/myproject/compile_commands.json ~/myproject-build/
+
+:raw-html:`</details>`
+
+:raw-html:`<details><summary markdown="span">Other build systems, using Bear</summary>`
+
+`Bear <https://github.com/rizsotto/Bear>`__ is a tool that generates a
+``compile_commands.json`` file by recording a complete build.
+
+For a ``make``-based build, you can run ``make clean; bear make`` to generate the
+file (and run a clean build!)
+
+:raw-html:`</details>`
+
+Other tools can also generate this file. See `the compile_commands.json
+specification <https://clang.llvm.org/docs/JSONCompilationDatabase.html>`__.
+
+``compile_flags.txt``
+---------------------
+
+If all files in a project use the same build flags, you can put those flags,
+one flag per line, in ``compile_flags.txt`` in your source root.
+
+Clangd will assume the compile command is ``clang $FLAGS some_file.cc``.
+
+Creating this file by hand is a reasonable place to start if your project is
+quite simple.
+
+Project-wide Index
+==================
+
+By default clangd only has a view on symbols coming from files you are
+currently editing. You can extend this view to whole project by providing a
+project-wide index to clangd. There are two ways to do this.
+
+- Pass an experimental `-background-index` command line argument. With
+ this feature enabled, clangd incrementally builds an index of projects
+ that you work on and uses the just-built index automatically.
+
+- Generate an index file using `clangd-indexer
+ <https://github.com/llvm/llvm-project/blob/master/clang-tools-extra/clangd/indexer/IndexerMain.cpp>`__
+ Then you can pass generated index file to clangd using
+ `-index-file=/path/to/index_file`. *Note that clangd-indexer isn't
+ included alongside clangd in the Debian clang-tools package. You will
+ likely have to build it from source to use this option.*

+What is clangd?
+===============
+
+clangd understands your C++ code and adds smart features to your editor: code
+completion, compile errors, go-to-definition and more.
+
+clangd is a language server that implements the `Language Server Protocol
+<https://github.com/Microsoft/language-server-protocol>`__; it can work with
+many editors through a plugin. Here's Visual Studio Code with the clangd
+plugin, demonstrating code completion:
+
+.. image:: CodeCompletionInVSCode.png
+ :align: center
+ :alt: Code completion in VSCode
+
+clangd is based on the `Clang <https://clang.llvm.org>`__ C++ compiler, and is
+part of the `LLVM <https://llvm.org>`__ project.
