Install Programs

Back

Install programs is a batch install GUI that installs mutliple programs via winget and/or Chocolatey.
It was made using a basic version of the custom game engine used for DREAD IT

Code Examples

Below is a snippet of the json file. This was a great way to quickly add new applications. "type" differentiates the categories and tabs in the ImGui interface. The other categories are how the programs are installed and what the package name is for choco and winget. If these didn't exist in command line install form, I also added a way to add the installer, which would be out of date if not updated but nonetheless existed. 


{	
    "7Zip": {
        "type" : "utilities",
        "winget": "7zip.7zip",
        "choco": "7zip",
        "installer" : "na",
        "uninstaller" : "na"
    },
    "Adobe Acrobat": {
        "type" : "media",
        "winget": "Adobe.Acrobat.Reader.64-bit",
        "choco": "adobereader",
        "installer" : "na",
        "uninstaller" : "na"
    },
    "AMD Ryzen Master": {
        "type" : "utilities",
        "winget": "na",
        "choco": "amd-ryzen-master",
        "installer" : "na",
        "uninstaller" : "na"
    },
    "Audacity": {
        "type" : "media",
        "winget": "Audacity.Audacity",
        "choco": "audacity",
        "installer" : "na",
        "uninstaller" : "na"
    }

Parsing uses json data and adding to a container

void App::Read(Stream& file)
{
  try
  {
    json jsonData = file.Get();

    for (const auto& item : jsonData.items()) {
      const String key = item.key();
      const String choco = item.value()["choco"];
      const String winget = item.value()["winget"];
      const String type = item.value()["type"];
      const String installer = item.value()["installer"];
      const String uninstaller = item.value()["uninstaller"];
  
      App app(key, choco, winget, installer, uninstaller, type);
      apps.push_back(app);
    }
  }
  catch (const std::exception& e) 
  {
    std::cerr << "Error parsing JSON: " << e.what() << std::endl;
    return;
  }
}

After the parsing is done, multiple tries of installs are made. Thinking back to the code, this could have been better implemented using a state machine rather than multiple if else checks. 

void App::Find(int _stall)
{
  String stall;
  _stall == 1 ? stall = "install " : stall = "uninstall ";
  
  int err = 0;
  if (_winget == "na") {
    err = -1;
  }
  else {
    // first try winget
    stall.insert(0, "winget ");
    _winget.insert(0, stall);
    std::cout << "";
    err = std::system(_winget.c_str());
  }
  
  if (err != 1 && err != 0) {
    if (_choco == "na") {
        err = -1;
    }
    else {
      // then try choco
      stall.insert(0, "choco ");
      _choco.insert(0, stall);
      std::cout << "";
      int err = std::system(_choco.c_str());
    }

    if (err != 1 && err != 0) {
      if (_installer == "na") {
        std::cerr << "Installation failed\n";
      }
      else {
        std::cout << "";
        _installer.insert(0, ".\\Data\\Executables\\");
        _uninstaller.insert(0, ".\\Data\\Executables\\");
        if (_stall == 1) {
            err = std::system(_installer.c_str());
        }
        else {
            err = std::system(_uninstaller.c_str());
        }
        if (err != 1) {
            std::cerr << "Installation failed\n";
        }
      }
    }
  }
}
