Removeing a group from INI file

[deepal_de]

Hello,
i have a INI file in following format.

[sys_1]
val1 = 10
val2 = 23
val3 = 23
 
[sys_2]
val1 = 56
val2 = 2
val3 = 27
 
[sys_3]
val1 = 84
val2 = 65
val3 = 12

[sys_1]
val1 = 10
val2 = 23
val3 = 23

[sys_2]
val1 = 56
val2 = 2
val3 = 27

[sys_3]
val1 = 84
val2 = 65
val3 = 12

To copy to clipboard, switch view to plain text mode 

what i need to do is remove sys_2 completely
so it will be like this

[sys_1]
val1 = 10
val2 = 23
val3 = 23
 
 
[sys_3]
val1 = 84
val2 = 65
val3 = 12

[sys_1]
val1 = 10
val2 = 23
val3 = 23


[sys_3]
val1 = 84
val2 = 65
val3 = 12

To copy to clipboard, switch view to plain text mode 

and if u can please post a example code , thanks ..

Hi,

Maybe with this:

QFile file("in.ini");
    if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
        return;
    QTextStream in(&file);
    QString currentGroup;
    QStringList temp;
    int pos;
    int pos2;
    QString grupToDelete;
    grupToDelete = "SomeThing";
    while (!in.atEnd())
    {
        QString line = in.readLine();
        if (line.contains("[") && line.contains("]")) //If it is a group
        {
            pos = line.indexOf("[");
            pos2 = line.indexOf("]");
            currentGroup = line.mid(pos+1,pos2-1); //Get the group
        }
        if (currentGroup != grupToDelete) //If the line is not the group to delete
        {
            temp.append(line); //Move the lines to temp
        }
    }
    //Temp will now have all the lines but those to delete
    //So save temp to out.ini
    QFile ofile("out.ini");
    if (!ofile.open(QIODevice::WriteOnly | QIODevice::Text))
        return;
    QTextStream out(&ofile);
    for (pos = 0; pos <= temp.count()-1;pos++)
        out << temp[pos] << "\n";
 
    QFile::remove("ini.ini"); //Remove the old file
    QFile::rename("out.ini","in.ini"); //Rename out to in

QFile file("in.ini");
    if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
        return;
    QTextStream in(&file);
    QString currentGroup;
    QStringList temp;
    int pos;
    int pos2;
    QString grupToDelete;
    grupToDelete = "SomeThing";
    while (!in.atEnd())
    {
        QString line = in.readLine();
        if (line.contains("[") && line.contains("]")) //If it is a group
        {
            pos = line.indexOf("[");
            pos2 = line.indexOf("]");
            currentGroup = line.mid(pos+1,pos2-1); //Get the group
        }
        if (currentGroup != grupToDelete) //If the line is not the group to delete
        {
            temp.append(line); //Move the lines to temp
        }
    }
    //Temp will now have all the lines but those to delete
    //So save temp to out.ini
    QFile ofile("out.ini");
    if (!ofile.open(QIODevice::WriteOnly | QIODevice::Text))
        return;
    QTextStream out(&ofile);
    for (pos = 0; pos <= temp.count()-1;pos++)
        out << temp[pos] << "\n";

    QFile::remove("ini.ini"); //Remove the old file
    QFile::rename("out.ini","in.ini"); //Rename out to in

I have no clue if an INI group can have subgroups.... If so... It will not remove any subgroups (like a tree) just the specified in grupToDelete.. You can make it a function so you can delete more than one group though.
Test it first!!!!

Just use QSettings::remove
