FileStateDatabase

A C++ class, that helps you to save the state of files in a sql database. It is a header only class.

Description

Build

• include FileStateDatabase.h
• compile with -lsqlite3 -lboost_system -lboost_filesystem -std=c++11
• example: clang++ main.cc -I . -lsqlite3 -lboost_system -lboost_filesystem -std=c++11

Example

Small example explains how to use FileStateDatabase. (see main.cc)

#include <FileStateDatabase.h>
#include <iostream>

int main(int argc, char **argv){

  if(argc <= 1){
    std::cout << "Usage: ./a.out /dir/to/generate/filestates" << std::endl;
    return 1;
  }

  boost::filesystem::path dir(argv[1]);
  FileStateDatabase fileStateDatabase("my_filestate_database", dir);

  // Get updates since last getUpdates
  std::vector<std::pair<FileState, ModState> > updates = fileStateDatabase.getUpdates();

  for(auto update: updates){
    FileState fs = update.first;
    ModState ms  = update.second;
    std::cout << "Update: " << fs.path << " " << fs.modtime << " " << FileStateDatabase::modStateToString(ms) << std::endl;

    // Propagate modstate into database
    fileStateDatabase.propagateUpdate(update);
  }

  return 0;
}
