使用 clang-format 自动格式化复杂代码

  • 772

我用clang-format它来自动格式化代码，在大多数情况下它可以应对爆炸，但有一段代码没有按照我们的意愿进行格式化。

从示例到库的一段代码（github 上的文件）：

int main(int argc, char* argv[])
{
    options.add_options()
      ("a,apple", "an apple", cxxopts::value<bool>(apple))
      ("b,bob", "Bob")
      ("f,file", "File", cxxopts::value<std::vector<std::string>>(), "FILE")
      ("i,input", "Input", cxxopts::value<std::string>())
      ("o,output", "Output file", cxxopts::value<std::string>()
          ->default_value("a.out")->implicit_value("b.def"), "BIN")
      ("positional",
        "Positional arguments: these are the arguments that are entered "
        "without an option", cxxopts::value<std::vector<std::string>>())
      ("long-description",
        "thisisareallylongwordthattakesupthewholelineandcannotbebrokenataspace")
      ("help", "Print help")
      ("int", "An integer", cxxopts::value<int>(), "N")
      ("option_that_is_too_long_for_the_help", "A very long option")
    ;
}

变成不可读的东西：

int main(int argc, char *argv[]) {
  options.add_options()("a,apple", "an apple",
                        cxxopts::value<bool>(apple))("b,bob", "Bob")(
      "f,file", "File", cxxopts::value<std::vector<std::string>>(),
      "FILE")("i,input", "Input", cxxopts::value<std::string>())(
      "o,output", "Output file",
      cxxopts::value<std::string>()->default_value("a.out")->implicit_value(
          "b.def"),
      "BIN")("positional",
             "Positional arguments: these are the arguments that are entered "
             "without an option",
             cxxopts::value<std::vector<std::string>>())(
      "long-description",
      "thisisareallylongwordthattakesupthewholelineandcannotbebrokenataspace")(
      "help", "Print help")("int", "An integer", cxxopts::value<int>(), "N")(
      "option_that_is_too_long_for_the_help", "A very long option");
}

.clang-format:

这可以以某种方式解决吗？

    一切都变得非常简单：

    int main(int argc, char* argv[])
{
  // clang-format off
  options.add_options()
    ("a,apple", "an apple", cxxopts::value<bool>(apple))
    ("b,bob", "Bob")
    ("f,file", "File", cxxopts::value<std::vector<std::string>>(), "FILE")
    ("i,input", "Input", cxxopts::value<std::string>())
    ("o,output", "Output file", cxxopts::value<std::string>()
        ->default_value("a.out")->implicit_value("b.def"), "BIN")
    ("positional",
      "Positional arguments: these are the arguments that are entered "
      "without an option", cxxopts::value<std::vector<std::string>>())
    ("long-description",
      "thisisareallylongwordthattakesupthewholelineandcannotbebrokenataspace")
    ("help", "Print help")
    ("int", "An integer", cxxopts::value<int>(), "N")
    ("option_that_is_too_long_for_the_help", "A very long option")
  ;
  // clang-format on
}

    借助评论

    // clang-format off
...
// clang-format on

    您可以禁用所需代码段的格式化。
