Qt regex modifier

[A Former User]

@mrjj I might, but the thing is that I need to use \u as it has a range: \uffff0-9.

I think that I'm going to drop the QRegularExpression and use QRegExp instead.

Well if it just accepts a \u I agree it seems more sensible than to figure out how to do \u like with QRegularExpression.

@mrjj It's kinda nonsense as QRegularExpresion came to be better than QRegExp, but anyway, let's stick with it as it's the only option left here.

Thank you.

btw
did u try
\x{FFFF}

[A Former User]

@mrjj Yes, I did and I got an error saying:

hex constants must have at least one hex digit

[A Former User]

@mrjj I fixed it, and it's working now... You just have to escape the \x, like \\x, for instance: [a-z\\x{00a1}-\\x{ffff}0-9]*.

@Minupi
Oh yes always escape "\"
Super- :)

@mrjj Thank you, helped a lot. I realised that QRegularExpression is using the same syntax as PHP.

[mrjj]

@Minupi
Good to hear. :)
It says its perl syntax but maybe PHP uses perl style or reverse?

[A Former User]

@mrjj Yes, it resembles perl style, it's called PCRE.

Hi,

To help you with your regular expression development, you can use the regular expression tool. It's available starting with Qt 5.6
