 **MacroBlockEnd** (``String``) :versionbadge:`clang-format 3.7` :ref:`¶ <MacroBlockEnd>`
   A regular expression matching macros that end a block.

+
+**Macros** (``List of Strings``) :versionbadge:`clang-format 17.0` :ref:`¶ <Macros>`
+  A list of macros of the form ``<definition>=<expansion>`` .
+
+  Code will be parsed with macros expanded, in order to determine how to
+  interpret and format the macro arguments.
+
+  For example, the code:
+
+  .. code-block:: c++
+
+    A(a*b);
+
+  will usually be interpreted as a call to a function A, and the
+  multiplication expression will be formatted as `a * b`.
+
+  If we specify the macro definition:
+
+  .. code-block:: yaml
+
+    Macros:
+    - A(x)=x
+
+  the code will now be parsed as a declaration of the variable b of type a*,
+  and formatted as `a* b` (depending on pointer-binding rules).
+
+  Features and restrictions:
+   * Both function-like macros and object-like macros are supported.
+   * Macro arguments must be used exactly once in the expansion.
+   * No recursive expansion; macros referencing other macros will be
+     ignored.
+   * Overloading by arity is supported: for example, given the macro
+     definitions A=x, A()=y, A(a)=a:
+
+
+  .. code-block:: c++
+
+     A; -> x;
+     A(); -> y;
+     A(z); -> z;
+     A(a, b); // will not be expanded.
