QCAD Bugtracker

Windows uses \r\n

Unices / MacOS use \n

Qt supports both.

As far as I know \r was only used on very old ("classic") MacOS systems up to about 2001. Since neither Qt nor QCAD ever ran on such a system, it's not feasible to support this obsolete file format. File converters are available online and offline.

It is not to run on such systems ... It is to read pattern files with that format.
At least the user should be warned that there is something not quite right.

At least I can catch it now and warn about a bad text data format:

    file = new QFile(fileName);
    flags = new QIODevice.OpenMode(QIODevice.ReadOnly);
    if (file.open(flags)) {
        var content = file.readAll();
        var pos1 = content.indexOf("\r");
        var pos2 = content.indexOf("\n");
        if (pos1>0 && pos1+1 !== pos2) { 
            debugger;    // Warn user that EOL = CR
        }
    }
    file.close();
