Generate a configuration file with an entry for each selection using Inno Setup

Question

Based on what I pick in Inno Setup, the installer should add an entry containing package name followed by , into config.ini

And extract the right premade config files (that are stored in the installer) needed for the few specific setups into the Config folder.

There are plenty of programs like Chrome/Firefox which don't need any parameters or additional configs to install.

Desired config.ini file syntax:

<package1>, <package2 /X /Y /Z>, <package 3> ...

Etc.

Where <packageX> is a string value tied to the checkboxes in the installer selection menu.

After Inno Setup completes, it should run a batch file.

Bonus points: Again.. not only output the config.ini, BUT also extract necessary premade configs set-up for the specific program into a folder C:/NKsetup/Config/

Answer 1

Add each each of your packages as a component to the Components section. Then in the Files section, you can choose what files get installed based on the components selected. For the packages list config file, you need to code that with use of the WizardIsComponentSelected function.

[Setup]
DefaultDirName=C:\some\path

[Types]
Name: "custom"; Description: "-"; Flags: iscustom

[Components]
Name: "sqlserver"; Description: "Microsoft SQL server"
Name: "chrome"; Description: "Google Chrome"
Name: "firefox"; Description: "Mozilla Firefox"

[Files]
Source: "install.bat"; DestDir: "{app}"
Source: "common-config.ini"; DestDir: "{app}"
Source: "sqlserver-config.ini"; DestDir: "{app}"; Components: sqlserver
Source: "browsers-config.ini"; DestDir: "{app}"; Components: chrome firefox

[Run]
Filename: "{app}\install.bat"; StatusMsg: "Installing..."

[Code]

procedure CurStepChanged(CurStep: TSetupStep);
var
  ConfigPath: string;
  Packages: string;
begin
  if CurStep = ssPostInstall then
  begin
    if WizardIsComponentSelected('sqlserver') then
    begin
      Packages := Packages + ',sql-server-express /X /Y /Z';
    end;
    if WizardIsComponentSelected('chrome') then
    begin
      Packages := Packages + ',chrome';
    end;
    if WizardIsComponentSelected('firefox') then
    begin
      Packages := Packages + ',firefox';
    end;

    // Remove the leading comma
    if Packages <> '' then
    begin
      Delete(Packages, 1, 1);
    end;

    ConfigPath := ExpandConstant('{app}\config.ini');
    // This is not Unicode-safe
    if not SaveStringToFile(ConfigPath, Packages, False) then
    begin
      Log(Format('Error saving packages to %s', [ConfigPath]));
    end
      else
    begin
      Log(Format('Packages saved to %s: %s', [ConfigPath, Packages]));
    end;
  end;
end;
