fastlib

  • fast_csv.hpp: Only one API fast_csv_parse_line to help parse csv easy with FSM, no any memory alloc duraing parsing
    std::string buffer = read_file("xxx.csv");
    const char* cursor = buffer.c_str();
    while(*cursor) {
       cursor = fastl::fast_csv_parse_line(cursor, [&](const char* v_start, const char* v_end) {
           // do somethings, store or parse the column value
           // std::string value(v_start, v_end);
       });
    
    or
    std::string buffer = read_file("xxx.csv");
    if(!buffer.empty()) {
      char* cursor = &buffer.front();
      while(*cursor) {
         cursor = fastl::fast_csv_parse_line(cursor, [&](char* v_start, char* v_end) {
             // if this column is int or double, is more Memory Efficient parse it directly
             char endch = *v_end; // store the last char in the streaming
             *v_end = '\0';
             int key = atoi(v_start); // parse int value directly
             *v_end = endch; // restore rthe last char in the stream
         });
     }
    
  • fast_split.hpp: Yeah, idea same with fast_csv.hpp
