* Rework documentation of the serialization converter exampleEdward Welbourne2023-11-011-0/+6
| | | | | | | | | | | | | | | | | | | The documentation was previously code-heavy and short on exposition, while focusing almost entirely on the CBOR converters. Prune most of the CBOR code quotes, shuffle some snippet markers, add and remove others and rewrite the main text. Shift focus to the base-class for converters and how it's used by main(). Retain relative focus on the CBOR converters, as they are relatively full-featured hence illustrate more than the others do, and replace the sequence of single-line sections about the others with a section collecting all into a table and saying some general things about them.

* Break out the list of available converters to a static methodEdward Welbourne2023-11-011-10/+17
| | | | | | | | | | | | | Mostly to pave the way for moving the class code to a file of its own, but this incidentally saves the need to std::as_const() every use. Moving the underlying object to a local static of a private method also saves the need for heap allocation (which was leaked).

* Rename Convert Example to Serialization ConverterEdward Welbourne2023-10-301-3/+3
| | | | | | | | | | | | The old name didn't say what sort of thing it was converting; and our guidelines for examples discourage using the word Example in the title. Also reword the description of the tool in the command-line parser and an assertion.

* Convert fprintf(stderr, ...); exit(EXIT_FAILURE); to qFatal(...)Edward Welbourne2023-10-301-12/+10
| | | | | | | | | | | | The serialization conversion example used raw C's way to abort on error; change to using Qt's way of doing the same. Likewise, convert the various other uses of fprintf(stderr, ...) to qWarning() and of printf(...) to qInfo().

* Deduplicate code in setup of serialization convertersEdward Welbourne2023-09-281-82/+49
| | | | | | | | | | | | | | | The setup of the input and output converters is fairly complex but was made harder to read by nearly-duplicating its logic for input and for output. Break out into a separate function to make clear what parts differ between the two and what parts don't. In the process, allow the search for a named converter to continue past a match that doesn't support the needed direction, on the off chance of a name collision. Make an error message more articulate in the process.

* Check input and output converters do support the relevant directionsEdward Welbourne2023-09-151-4/+7
| | | | | | | | | | | | It was previously possible to select an input-only converter for output or an output-only converter for input. Also add a comment to explain why failure to probe for the auto output converter isn't an error, where failure to probe for the auto input converter is.

Konrad pointed out, in review, a constructor that could be = default; it could, in fact, vanish entirely as a result.

| | | | | | | | | | | | A couple more compilation units could use Qt::StringLiterals. Prefer QL1SV for the code constants, to keep code small. Convert fpToString() to take QL1SV instead of const char *, with suffix empty by default. Also rearranged some spacing, some if it suggested by clang-tidy.

* Port from qAsConst() to std::as_const()Marc Mutz2022-10-111-6/+6
| | | | | | | | | | | | | | | | We've been requiring C++17 since Qt 6.0, and our qAsConst use finally starts to bother us (QTBUG-99313), so time to port away from it now. Since qAsConst has exactly the same semantics as std::as_const (down to rvalue treatment, constexpr'ness and noexcept'ness), there's really nothing more to it than a global search-and-replace, with manual unstaging of the actual definition and documentation in dist/, src/corelib/doc/ and src/corelib/global/.
