-**AlignConsecutiveAssignments** (``bool``)
- If ``true``, aligns consecutive assignments.
+**AlignConsecutiveAssignments** (``AlignConsecutiveAssignmentsStyle``)
+ Style of aligning assignments on consecutive lines.
- This will align the assignment operators of consecutive lines. This
- will result in formattings like
+ Possible values:
+
+ * ``ACA_None`` (in configuration: ``None``)
+ Do not align consecutive assignments.
+
+ * ``ACA_Consecutive`` (in configuration: ``Consecutive``)
+ Align assignments on consecutive lines. This will result in
+ formattings like
+
+ .. code-block:: c++
+
+ int aaaa = 12;
+ int b = 23;
+ int ccc = 23;
+
+ * ``ACA_AcrossEmptyLines`` (in configuration: ``AcrossEmptyLines``)
+ Same as ACA_Consecutive, but alignment also spans over empty
+ lines, e.g.
+
+ .. code-block:: c++
+
+ int aaaa = 12;
+ int b = 23;
+
+ int ccc = 23;
+
+ * ``ACA_AcrossComments`` (in configuration: ``AcrossComments``)
+ Same as ACA_Consecutive, but alignment also spans over empty
+ lines and lines containing only comments, e.g.
+
+ .. code-block:: c++
+
+ int aaaa = 12;
+ int b = 23;
+
+ /* This is a comment */
+ int ccc = 23;
- .. code-block:: c++
- int aaaa = 12;
- int b = 23;
- int ccc = 23;
**AlignConsecutiveBitFields** (``bool``)
If ``true``, aligns consecutive bitfield members.
