Hi Luca,

In my opinion you should not release your application with such an
obvious crash bug. It's not only this expression, the program crashes
whenever there is anything wrong in that text field. That's not
something you can defer to the next release.

I don't know if it makes sense, but you should have a look at the
calligra sheets part (aka talk to someone who knows about it).
Eventually that can be very useful for this purpose (unfortunately I
don't know exactly how they work).

You could replace a 2000+ character boolean logic expression which
lists all the letters in the alphabet by this:
  c.isLetter() || QString("+-*/^").contains(c)
at least assuming you do the other thing I said and use QString
instead of char*.
This is a cleanup which is worth doing.

Writing correctly formatted code is mostly a matter of setting up your
editor correctly. Spend five minutes doing that ;)
