* Add QStringView::count(...)Lars Knoll2020-10-151-0/+3
| | | | | | | | | | | Also this one as a porting aid towards Qt 6. The implementation is using QString to keep things simple.

* Add QStringView::split()Lars Knoll2020-10-151-0/+14
| | | | | | | | | | The implementation has to live in qstringlist.h and qregularexpression.h, as those classes are only forward declared in qstring.h. Task-number: QTBUG-86516 Change-Id: Ia9b3ff48999d1c2e7df905191ee192764b309d08 Reviewed-by: Mårten Nordheim <marten.nordheim@qt.io>
* Add toInt() and friends to QStringViewLars Knoll2020-10-121-0/+11
| | | | | | | | | | | | | The implementations are not trimmed for efficiency, but as a porting help for Qt 6. Because of that, they simply use the methods available in QString.

* Loosen the API contract for QStringView::left() and friendsLars Knoll2020-10-121-4/+12
| | | | | | | | | | | | | Remove the assertions in QStringView::left() and friends and turn them into runtime bounds checking instead. This changes the behavior to be compatible with what we do in Qt 6 (see change d2833a3ce5af725d66ef9338f2a61b766dd3cb2d) and simplifies porting from QStringRef to QStringView.

* Fix warning in QStringView::compare(QChar) on qsizetype->intThiago Macieira2020-07-311-1/+4
| | | | | | | | | | | | | | | | | | | size() - 1 is converted to int as the result, but size() is a qsizetype and could be bigger than INT_MAX. So rewrite to not depend on the cast. This was introduced on b2f79cceb11dfd15ac9eea631bc18ad6b036eb91. I could have replaced size() - 1 with int(size() > 1) - 1, but that's even more complex. To simplify, I split the function in two while retaining the C++11 constexpr requirements. Bonus: removes the use of the ambiguously-named "empty()" function that looks like a verb.

* QStringView: adapt to C++20 constexpr std::basic_stringMarc Mutz2020-03-121-1/+1
| | | | | | | | | | | | Just mark the constructor constexpr. If std::basic_string isn't, then this will be silently dropped. If std::basic_string is, we can now construct QStringView from std::basic_strings at compile-time. [ChangeLog][QtCore][QStringView] Conversion from std::basic_string can now be constexpr (when std::basic_string is).

* Introduce QString(View)::isValidUtf16Giuseppe D'Angelo2019-12-201-0/+2
| | | | | | | | | | | | | | | | | | | QString(View)s can be built or manipulated in ways that make them contain/refer to improperly encoded UTF-16 data. Problem is, we don't have public APIs to check whether a string contains valid UTF-16. This knowledge is precious if the string is to be fed in algorithms, regular expressions, etc. that expect validated input (e.g. QRegularExpression can be faster if it can assume valid UTF-16, otherwise it has to employ extra checks). Add a function that does the validation. [ChangeLog][QtCore][QStringView] Added QStringView::isValidUtf16. [ChangeLog][QtCore][QString] Added QString::isValidUtf16.

* Deprecate QStringViewLiteralMarc Mutz2019-08-101-0/+7
| | | | | | | | | | | | | | | | | As a macro, we can't directly deprecate it, but need to make it call something deprecated. That is a new ctor with a new enum type added. The type might be useful for other such ventures, so put it into qglobal.h Remove the QT_NO_UNICODE_LITERAL protection, as it's always false these days, and QT_UNICODE_LITERAL is unconditionally #defined a 20 lines above. [ChangeLog][QtCore][QStringView] Deprecated the (undocumented) QStringViewLiteral macro. Just use u"" or QStringView(u"") instead.

* QStringView: two fixes for newly-added toWCharArray()Marc Mutz2019-07-291-1/+1
| | | | | | | | | | | | | | | | | | | | Amends e89fbd8c3aa50a24e5fc02ab710ccca67fce98e2. - While QString::data() never returns nullptr, QStringView::data() may, which makes calling QStringView{}.toWCharArray() UB on Windows (since memcpy's 2nd argument must never be nullptr, even if the size is zero). Fix by protecting the memcpy call. - QStringView, by design, does not use out-of-line member functions, because calling these forces the QStringView object onto the stack. Fix by making inline. Also use the more efficient qToStringViewIgnoringNull(), as the result does not depend on QString::isNull() (no characters are written either way), and add a missing article to the function's docs.
