How to make empty lines in the created INI file during installation in Inno Setup?

Question

The fact is that the text I have goes one after the other:

[Nancy Data]
CDDrive1=C:
CDDrive2=C:
HDDrive=C:
IDPath=\Program Files (x86)\My Program\Нэнси Дрю. Секреты могут убивать

CDSoundPath=\Program Files (x86)\My Program\Нэнси Дрю. Секреты могут убивать\CDSound\
LoadSavePath=\Program Files (x86)\My Program\Нэнси Дрю. Секреты могут убивать\Save\

SoundBufSize=4096           ; size used if forced
SoundBufSkip=6              ; raise if sound skips, lower if video not synching

PrimaryVideoNonSoundFrameTime=66
SystemQualityForPrimaryVideo=0
InstallationType=0
PlayerWonTheGame=StillWorkingOnIt
; 640x480 aspect=1.33 : 1

And I need to format the INI file by inserting empty lines between key groups:

[Nancy Data]

CDDrive1=E:\
CDDrive2=E:\

I am creating an INI file using the INI section:

I found the Format function with this example:

var
  S: String;
  I: Integer;
begin
  S := Format('%d files found', [10]);
  // S = '10 files found'

  S := Format('Filename: %s', ['file.txt']);
  // S = 'Filename: file.txt'

  I := 64;
  S := Format('%d in hex, padded to 8 digits: %.8x', [I, I]);
  // S = '64 in hex, padded to 8 digits: 00000040'
end;

But I didn't understand how I could use it.

Answer 1

While you didn't even told us, I assume that you use [INI] section to create your INI file. As empty lines have no meaning in INI file, neither does Windows INI file API have any means to add empty lines (and consequently neither does Inno Setup API, which is build on top of Windows API).

If you want to make custom modifications to the INI file, you have to treat it as an unstructured text file, not as an INI file.

For some examples, see:

• Insert a line to a text file/template in Inno Setup before a specific line if doesn't exist yet
• How can I add comments in INI file created by Inno Setup installation

Another thing that you can do, if you are creating a new INI file, is to deploy a template INI file with the formatting you want to achieve. And then use the [INI] section to only modify the keys.

[Files]
; Deploy INI file template
Source: "config.ini"; DestDir: "{app}"

[INI]
; Modify the key values, which are determined during installation only
Filename: "{app}\config.ini"; Section: "Section"; Key: "Key"; \
    String: "{code:GetValue}";
