+====================================
+Query Based Custom Clang-Tidy Checks
+====================================
+
+Introduction
+============
+
+This page provides examples of how to add query based custom checks for
+:program:`clang-tidy`.
+
+Custom checks are based on clang-query syntax. Every custom checks will be
+registered in `custom` module to avoid name conflict. They can be enabled or
+disabled by the checks option like the builtin checks.
+
+Custom checks support inheritance from parent configurations like other
+configuration items.
+
+Configuration
+=============
+
+`CustomChecks` is a list of custom checks. Each check must contain
+ - Name: check name can been used in `-checks` option.
+ - Query: query string
+ - Diagnostic: list of diagnostics to be reported.
+ - BindName: name of the node to be bound in `Query`.
+ - Message: message to be reported.
+ - Level: severity of the diagnostic, the possible values are `Note`,
`Warning`, `Error`.
+
+Example
+=======
+
+.. code-block:: yaml
+
+ Checks: -*,custom-call-main-function
+ CustomChecks:
+ - Name: call-main-function
+ Query: |
+ match callExpr(
+ callee(
+ functionDecl(isMain()).bind("fn")
+ )
+ ).bind("callee")
+ Diagnostic:
+ - BindName: fn
+ Message: main function.
+ Level: Note
+ - BindName: callee
+ Message: call to main function.
+ Level: Warning
+
+.. code-block:: c++
+
+ int main(); // note: main function.
+
+ void bar() {
+ main(); // warning: call to main function. [custom-call-main-function]
+ }
