如何使用clang格式缩进C ++编译指示？ [英] How could I indent C++ pragma using clang-format?

问题描述

我正在使用 vim-autoformat ，它使用 clang-format 作为外部格式化程序。

I am using vim-autoformat, which uses clang-format as external formatter.

似乎 clang格式不会缩进C ++ #pragma 。例如：

It seems that clang-format won't indent the C++ #pragma. For example:

#include <omp.h>
#include <cstdio>
int main()
{
#pragma omp parallel for
    for (int i = 0; i < 10; ++i)
    {
        puts("demo");
    }
    return 0;
}

我希望将其格式化为：

#include <omp.h>
#include <cstdio>
int main()
{
    #pragma omp parallel for
    for (int i = 0; i < 10; ++i)
    {
        puts("demo");
    }
    return 0;
}

我检查了语言格式，但是找不到我可以使用的选项。

I checked clangformat, but didn't find which option I could use.

推荐答案

来晚了，但这是您正在寻找的解决方案。
它将格式说明和代码块一起格式化。

It's been late but this is the solution you are looking for. It formats the pragma along with the code block.

主要概念是替换字符串，以便格式化程序在这些编译指示上使用正确规则。动机示例如下。

The main concept is replacing the string so that the formatter uses the "correct" rules on these pragmas. The motivative example is as following.

# Replace "#pragma omp" by "//#pragma omp"
sed -i 's/#pragma omp/\/\/#pragma omp/g' ./main.c
# Do format
clang-format ./main.c
# Replace "// *#pragma omp" by "#pragma omp"
sed -i 's/\/\/ *#pragma omp/#pragma omp/g' ./main.c
