c++ - 使 Clang-Format 忽略换行符的注释

Question

是否可以告诉 Clang-Format 忽略换行操作的注释？这个想法是遵循“代码格式良好，即使注释超过换行边距”的风格。如果代码不超过边距，则不应将代码分成多行，但注释会。

例如

//desired behaviour:
short code = shortCode + 
        longlonglongCode;
short code = shortCode; //long comment without a line break

//not desired behaviour:
short code =
    shortCode;  //long comment without a line break

Answer 1

ReflowComments: (bool)

If true, clang-format will attempt to re-flow comments.

false:
// veryVeryVeryVeryVeryVeryVeryVeryVeryVeryVeryLongComment with plenty of information
/* second veryVeryVeryVeryVeryVeryVeryVeryVeryVeryVeryLongComment with plenty of information */

true:
// veryVeryVeryVeryVeryVeryVeryVeryVeryVeryVeryLongComment with plenty of
// information
/* second veryVeryVeryVeryVeryVeryVeryVeryVeryVeryVeryLongComment with plenty of
 * information */

使用ReflowComments: true，启用后它会在//后添加1个空格，并在达到限制时停止注释。

可以使用PenaltyBreakComment进行调整。
例如。阻断刹车线 PenaltyBreakComment: 1000000000
