在 if() while() for() 之后的语句周围添加 {}

Question

我想知道是否可以设置 clang-format 以减少非 compound_statement进入 { non-compound_statement; }在 iteration_statement .

statement
: labeled_statement
| compound_statement
| expression_statement
| selection_statement
| iteration_statement
| jump_statement
;
iteration_statement
: WHILE '(' expression ')' statement
| DO statement WHILE '(' expression ')' ';'
| FOR '(' expression_statement expression_statement ')' statement
| FOR '(' expression_statement expression_statement expression ')' statement
;

示例

输入:

if (exp) foo = 1;

输出:

if (exp) { foo = 1; }

然后美化器会根据需要缩进。

您想要做的超出了 clang-format 试图实现的范围:

• The only lexical elements clang-format should touch are: whitespaces, string-literals and comments. Any other changes ranging from ordering includes to removing superfluous paranthesis are not in the scope of this tool.

然而，clang tidy 可以，功能标志被称为 readability-braces-around-statements .
