i am workin on a terminal program to execute applications on remote machines. you can pass a command like in the windows cmd.exe like:
"C:\random Directory\datApplication.py" "validate" -r /c "C:\anotherDirectory"
to make that possible i have to deal with quoted text and parse the command and its arguments from that string.
in notepad++ i found a RegExp to patch them (([^" \t\n]+)|("[^"]*"))+ and it works. in Qt4.8.1 i tried:
static const QRegExp re("(([^\" \\t\\n]+)|(\"[^\"]*\"))+");
re.matchExact(str); // str is something like shown above
qDebug() << re.capturedTexts();
and this code only prints me 3 times the "C:\random Directory\datApplication.py" and nothing more.
it should print out every argument entered as a single object ...
what can i do to make it working?
SOLUTION: (thanks to Lindrian)
const QString testText = "\"C:\\random Directory\\datApplication.py\" \"validate\" -r /c \"C:\\anotherDirectory\"";
static const QRegExp re("([^\" \\t\\n]+|\"[^\"]*\")+");
int pos = 0;
while ((pos = re.indexIn(testText)) != -1) //-i indicates that nothing is found
{
const int len = re.matchedLength();
qDebug() << testText.mid(pos,len);
pos += len;
}
FTFY: ([^" \t\n]+|"[^"]*")
(You were just overusing backrefs)
Make sure you're capturing all results.
