C/C++ Unix配置文件库

Question

在哪里可以找到用于读取和操作Unix配置文件的C或C++库(format: name=value\n)？

Answer 1

我建议你使用boost :: property_tree库来实现C++.它有安静的详细手册.此外,我建议你使用"info"配置文件.

配置文件示例:

; this is just comment line

firstParamSection 
{
   stringParam "string"
   intParam 10
}

从配置文件中检索此参数的代码示例:

#include <boost/property_tree/ptree.hpp>
#include <boost/property_tree/info_parser.hpp>
#include <string>

int main (int argc, char *argv[]) {
  std::string testString;
  int testInt;

  boost::property_tree::ptree pTree;
  try {
    read_info("test/config/file/name", pTree);
  }
  catch (boost::property_tree::info_parser_error e) {
    std::cout << "error" << std::endl;
  }

  try {
    testString = pTree.get<std::string>("firstParamSection.stringParam");
    testInt = pTree.get<int>("firstParamSection.intParam");
  }

  catch(boost::property_tree::ptree_bad_path e) {
    std::cout << "error" << std::endl;
  }
