c++ - Can I use a mask to iterate files in a directory with Boost? -


i want iterate on files in directory matching "somefiles*.txt". boost::filesystem have built in that, or need regex or against each leaf()?

edit: noted in comments, code below valid versions of boost::filesystem prior v3. v3, refer suggestions in comments.

boost::filesystem not have wildcard search, have filter files yourself.

this code sample extracting content of directory boost::filesystem's directory_iterator , filtering boost::regex:

const std::string target_path( "/my/directory/" ); const boost::regex my_filter( "somefiles.*\.txt" );  std::vector< std::string > all_matching_files;  boost::filesystem::directory_iterator end_itr; // default ctor yields past-the-end for( boost::filesystem::directory_iterator i( target_path ); != end_itr; ++i ) {     // skip if not file     if( !boost::filesystem::is_regular_file( i->status() ) ) continue;      boost::smatch what;      // skip if no match v2:     if( !boost::regex_match( i->leaf(), what, my_filter ) ) continue;     // v3:     //if( !boost::regex_match( i->path().filename(), what, my_filter ) ) continue;      // file matches, store     all_matching_files.push_back( i->leaf() ); }

(if looking ready-to-use class builtin directory filtering, have @ qt's qdir.)
