How should I use directory_iterator
to list directory files (not recursive)?
Also what header files / libs should I add/link or other settings I should make? I'm using boost in my project but by some reason directory_iterator
is "underclared identifier" while I can use other boost features.
Update
Another solution:
#include <filesystem>
#include <boost/filesystem.hpp>
#include <iostream>
using namespace boost::filesystem;
for (directory_iterator itr(path_ss); itr!=directory_iterator(); ++itr)
{
cout << itr->path().filename() << ' '; // display filename only
if (is_regular_file(itr->status())) cout << " [" << file_size(itr->path()) << ']';
cout << '\n';
}
The tut3 example is what you're looking for:
See it Live on Coliru
Here's a simplified version based on c++11:
#include <boost/filesystem.hpp>
#include <boost/range/iterator_range.hpp>
#include <iostream>
using namespace boost::filesystem;
int main(int argc, char *argv[]) {
path p(argc>1? argv[1] : ".");
if(is_directory(p)) {
std::cout << p << " is a directory containing:\n";
for(auto& entry : boost::make_iterator_range(directory_iterator(p), {}))
std::cout << entry << "\n";
}
}
You can see I linked boost_system (for the errorcode facilities) and boost_filesystem:
g++ -std=c++11 -Os -Wall -pedantic main.cpp -lboost_system -lboost_filesystem && ./a.out .
"." is a directory containing:
"./main.cpp"
"./a.out"
