Split QString only at unescaped slash

[jefftee]

Qt doesn't require double backslashes, it's the C++ compiler that requires the double backslashes in quoted strings. If you are getting the string from user input or reading from a file, double backslashes are not required. This example reads the string from the file:

QFile f("/Users/jefft/test.txt");
f.open(QFile::ReadOnly);
QString str = f.readLine();
f.close();
QRegularExpression re("\\/(?<!\\\\\\/)");
QStringList strlist = str.split(re);

QFile f("/Users/jefft/test.txt");
f.open(QFile::ReadOnly);
QString str = f.readLine();
f.close();
QRegularExpression re("\\/(?<!\\\\\\/)");
QStringList strlist = str.split(re);

To copy to clipboard, switch view to plain text mode 

Where the test.txt file contains:

hello/world/how\/are/you

This should be the same if your text is coming from a QLineEdit, etc.
