链接到目录中所有文件的惯用方法(包括文件夹、src等)

最后写了一个小脚本,尽管这可能不是最简单/最有效的方法,但它仍然达到了预期的效果。只需获取一个包含所有头文件和源文件的字符串就非常有用了,这些头文件和源文件可以与 cp [headers] /path/to/dst

#include <iostream>
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <list>

/*
* Recursively navigates the file tree and finds all .h header files
* and all .cpp files, to be used to "scrape" large codebases
*   
*/

std::list<std::string> source_list = {};
std::list<std::string> header_list = {};

int is_dir(const char *path)
{
    struct stat statbuf;
    if (stat(path, &statbuf) != 0)
        return 0;
    return S_ISDIR(statbuf.st_mode);
}


void dirSearch(std::string p)
{
    FILE *fp;
    char path[100];

    std::string cd = "cd ";
    std::string ls = " && ls";
    std::string cmd = cd + p + ls;

    fp = popen(cmd.c_str(), "r");
    if (fp == NULL) {
        printf("Failed to run command\n");
        exit(1);
    }
    while (fgets(path, sizeof(path)-1, fp) != NULL) {

        std::string abs_path = p + "/" + path;

        // rm \n
        abs_path.pop_back();

        // any folder can be a path to search for headers in
        if ( is_dir(abs_path.c_str()) ) {
            dirSearch(abs_path);
        }
        // if not a directory, check if the file is a .cpp file and add to list of source files 
        else {
            std::string SOURCE_FILE_EXT = ".cpp";

            if (abs_path.substr(abs_path.size() - SOURCE_FILE_EXT.size(), abs_path.size()) == SOURCE_FILE_EXT) {
                source_list.push_back(abs_path);
            }

            std::string HEADER_FILE_EXT = ".h";

            if (abs_path.substr(abs_path.size() - HEADER_FILE_EXT.size(), abs_path.size()) == HEADER_FILE_EXT) {
                header_list.push_back(abs_path);
            }
        }
    }
    pclose(fp);
}

int main(int argc, char **argv)
{
    dirSearch(argv[1]);

    std::string headers = "";
    std::string fsource = " ";
    
    // add header path
    for (std::string l : header_list) {
        all_header_files += " " + l;
    }
    // add source files
    for (std::string l : source_list) {
        all_source_files += " " + l;
    }

    std::cout << all_header_files << std::endl;
    std::cout << all_source_files << std::endl;
}

下面是一个示例用法:

g++ scrape_source.cpp -o scrape_source
./scrape_source PhysX-4.1
