Detailed Description

File and directories basic tools.

The example below shows how to manipulate the functions of this class to create first a directory which name corresponds to the user name and then create a file in this directory.

#include <iostream>
#include <string>
#include <fstream>
#include <visp/vpIoTools.h>
int main()
{
  std::string username;
  vpIoTools::getUserName(username);
  // Test if a username directory exist. If no try to create it
  if (vpIoTools::checkDirectory(username) == false) {
     try {
       // Create a directory with name "username"
       vpIoTools::makeDirectory(username);
     }
     catch (...) {
       std::cout << "Cannot create " << username << " directory" << std::endl;
       return false;
     }
   }
  // Create a empty filename with name "username/file.txt"
  std::ofstream f;
  std::string filename = username + "/file.txt";
  filename = vpIoTools::path(filename); // Under Windows converts the filename string into "username\\file.txt"
  std::cout << "Create: " << filename << std::endl;
  f.open(filename.c_str());
  f.close();
  // Rename the file
  std::string newfilename = username + "/newfile.txt";
  std::cout << "Rename: " << filename << " in: " << newfilename << std::endl;
  if (vpIoTools::rename(filename, newfilename) == false)
    std::cout << "Unable to rename: " << filename << std::endl;
  // Remove the file
  std::cout << "Remove: " << newfilename << std::endl;
  if (vpIoTools::remove(newfilename) == false)
    std::cout << "Unable to remove: " << newfilename << std::endl;
}

The example below shows how to read a configuration file and how to create a name for experiment files. We assume the following file "/home/user/demo/config.txt" :

expNumber 2
save 0
lambda 0.4
use2D 0
use3D 1

#include <iostream>
#include <string>
#include <visp/vpIoTools.h>
int main()
{
  // reading configuration file
  vpIoTools::loadConfigFile("/home/user/demo/config.txt");
  std::string nExp;vpIoTools::readConfigVar("expNumber", nExp); // nExp <- "2"
  double lambda;vpIoTools::readConfigVar("lambda", lambda);     // lambda <- 0.4
  bool use2D;vpIoTools::readConfigVar("use2D", use2D);          // use2D <- false
  bool use3D;vpIoTools::readConfigVar("use3D", use3D);          // use3D <- true
  bool doSave;vpIoTools::readConfigVar("save", doSave);         //  doSave <- false
  // creating name for experiment files
  vpIoTools::setBaseDir("/home/user/data");
  vpIoTools::setBaseName("exp" + nExp);         // full name <- "/home/user/data/exp2"
  vpIoTools::addNameElement("2D", use2D);       // full name <- "/home/user/data/exp2" since use2D==false
  vpIoTools::addNameElement("3D", use3D);       // full name <- "/home/user/data/exp2_3D"
  vpIoTools::addNameElement("lambda", lambda);  // full name <- "/home/user/data/exp2_3D_lambda0.4"
  // saving file
  vpIoTools::saveConfigFile(doSave); // would copy "/home/user/demo/config.txt" to "/home/user/data/exp2_3D_lambda0.4_config.txt" if doSave was true
  // create sub directory
  vpIoTools::createBaseNamePath();  // creates "/home/user/data/exp2_3D_lambda0.4/"

void vpIoTools::getUserName ( std::string & username )

Get the user name.

Under unix, get the content of the LOGNAME environment variable.

This is more flexible precisely because the user can set LOGNAME arbitrarily.
Under windows, uses the GetUserName() function.
