It's increasingly common for YAML to be used as metadata in front of
markdown documents. md4c does not handle this, so we need to remove
it ahead of time, lest md4c misinterpret it as heading text or so.
The --- fences are expected to be consistent regardless of the format of
what's between them, and the yaml (or whatever) parser does not need to
see them. So we remove them while reading, and QTextMarkdownWriter
writes them around the front matter if there is any.
If your application needs to parse this "front matter", just call
qtd->metaInformation(QTextDocument::FrontMatter).toUtf8() and feed that
to some parser that you've linked in, such as yaml-cpp.
Since YAML is used with GitHub Docs, we consider this feature to be part
of the GitHub dialect:
https://docs.github.com/en/contributing/writing-for-github-docs/using-yaml-frontmatter
[ChangeLog][QtGui][Text] Markdown "front matter" (usually YAML) is now
extracted during parsing (GitHub dialect) and can be retrieved from
QTextDocument::metaInformation(FrontMatter). QTextMarkdownWriter also
writes front matter (if any) to the output.

The DirectWrite font backend is an optional backend which
is planned to take over as the default on Windows. In order
to do this, though, a few gaps need to be filled in order
for it to pass all autotests.
The following things are covered by this:
1. Bitmap fonts are unsupported in DirectWrite. We enumerate
these using GDI and fall back to the GDI font engine when
loading them. As part of this, we introduce a new handle
type for fonts on Windows which can represent both
the DirectWrite and GDI engines.
2. "Legacy font names" where sub-family is embedded in the
family name is now enumerated together with the
typographic font name.
3. The DirectWrite font engine was not loading kerning pairs
from the font, like the other engines (omission which was
detected by the test)
4. Turning off antialiasing does not work with DirectWrite, so
we fall back to GDI for this.
5. Loading supported writing systems from application fonts
was not supported.

In md4c 0.4.8, three or more hyphens immediately after text were seen as
a thematic break:
some text
---
But in 0.5.1 it makes the text into an H2 heading (even though this
style of heading would normally have the text fully "underlined" with
hyphens). The CommonMark spec 0.30 says
If a line of dashes that meets the above conditions for being a
thematic break could also be interpreted as the underline of a setext
heading, the interpretation as a setext heading takes precedence.
Thus, for example, this is a setext heading, not a paragraph followed
by a thematic break:
https://spec.commonmark.org/0.30/#example-59
So the new behavior seems more correct. But rather than testing so
deeply, just disambiguate by adding a newline, since Qt may be expected
to work with various versions of md4c, and such minor behavior
differences are not expected to come up often in practice.
QTextMarkdownWriter already adds a newline when writing such markdown.

The object replacement character (U+FFFC) is used to represent
inline objects such as images in rich-text. To enable this,
we have special handling of it in QTextEngine. For classes
where inline images are not supported, it will just be hidden
from the visual text, which is unexpected.
Instead of always special-casing it, we make this dependent
on whether the document layout has registered any object handlers.
If they have not, then there will be no visual representation of
the object, and it is better to show the glyph for it.
For anything based on QTextDocument, there will always be the
image handler, so U+FFFC will still have special handling there,
but for non-rich labels and plain text editors the glyph will
be shown instead.
Note that there was also a bug in QLineEdit, where the object
replacement character was always replaced by a space. This was
introduced in 2007, in a patch which replaced a !ch.isPrint()
with a check for "the most obvious non-printable characters"
to reduce the number of characters that were not shown. However,
U+FFFC is a printable character and would thus not have been
filtered by the !isPrint() condition, so I think this was a
mistake at the time. However, due to the special-casing of
the character in Qt, it would not have had any effect until
now.
This also changes the QTextLayout::cursorToXForInlineObject()
test to actually test proper inline objects, as this was
previously using a hack which depended on the inline object
code to be used even for plain QTextLayouts with no handlers
for these.
[ChangeLog][Text] The object replacement character (U+FFFC)
is now only filtered out in rich text controls, where they
represent inline objects. In other controls, its glyphs will
be shown as with other text.

Variant-selectors are special unicode symbols which are used to
modify glyph selection for the preceding character. For instance,
a regular symbol could be turned into a color emoji using VS16,
the emoji variation selector. In order for this to work, however,
the font that handles the selector has to handle the full pair of
characters, so that it can apply the correct substitution rules.
One specific example of this was on macOS, where an airplane
symbol + VS16 would match the symbol to the default UI font but
the VS16 to the emoji font. Since there string provided for the
emoji font did not have any preceding character for VS16, we just
ignored it.
To improve on this, we now detect variation selectors that have
been matched to different font engines than the preceding
character. When such a case occurs, we check if the selector font
also supports the preceding character, and if it does, we keep
the pair together and use the same font for both.
[ChangeLog][QtGui][Text] Fix some cases where a variation-selector
character would be ignored in font selection and the correct
variant of a character would thus not be selected.

This amends fccd419dd6.
If Harfbuzz failed on one of the items in a string and returned
zero glyphs, then we would exit the shaping loop. The mentioned
change fixed a crash related to this when the ignored character
was the only character in the string, but it occurred in a
subitem of a longer string, then we would return and fail to
lay out the rest of the string.
This popped up recently because an update to Harfbuzz has caused
it to return zero glyphs when applying the Apple emoji font to
an isolated variant character (see bug report). When we matched
the symbol to the main font and only the variant character to
the emoji font, we would get in this situation, and end up
exiting the shaping early.
[ChangeLog][QtGui][Text] Fixed a regression which would
sometimes cause text to disappear if the string contained
an unmatched variation selector character.

When Harfbuzz returns zero glyphs, this will typically be because
the character is ignored. We currently have no way to differentiate
this from actual error cases, so to avoid return the error glyph
for cases which are not really errors, we set the dontPrint flag
for this.
When we add a way to differentiate between error cases and non-error
cases later, we should revert this for the actual errors.

This is improved version of previous fix
013c346a8d that was reverted because it
broke some tests for Quick Text. The problem was that it did not work
correctly in the case the text was wrapped to a fixed width.
To deal with this we'll accumulate current line full width (as if it
hadn't been wrapped) in layout data (layoutData->currentMaxWidth).
Then when the next line is explicitly wrapped by line or paragraph
separator, this accumulated width will be used to adjust layout's
maximum width.

When comparing a glyphIndex with a hard coded number, the number is
cast to an int, whereas the glyphIndex is an unsigned int.
That causes a compiler warning.
This patch forces the numbers to be cast to an unsigned int.

This is a semantic patch using ClangTidyTransformator as in
qtbase/df9d882d41b741fef7c5beeddb0abe9d904443d8, but extended to
handle typedefs and accesses through pointers, too:
const std::string o = "object";
auto hasTypeIgnoringPointer = [](auto type) { return anyOf(hasType(type), hasType(pointsTo(type))); };
auto derivedFromAnyOfClasses = [&](ArrayRef<StringRef> classes) {
auto exprOfDeclaredType = [&](auto decl) {
return expr(hasTypeIgnoringPointer(hasUnqualifiedDesugaredType(recordType(hasDeclaration(decl))))).bind(o);
};
return exprOfDeclaredType(cxxRecordDecl(isSameOrDerivedFrom(hasAnyName(classes))));
};
auto renameMethod = [&] (ArrayRef<StringRef> classes,
StringRef from, StringRef to) {
return makeRule(cxxMemberCallExpr(on(derivedFromAnyOfClasses(classes)),
callee(cxxMethodDecl(hasName(from), parameterCountIs(0)))),
changeTo(cat(access(o, cat(to)), "()")),
cat("use '", to, "' instead of '", from, "'"));
};
renameMethod(<classes>, "count", "size");
renameMethod(<classes>, "length", "size");
except that the on() matcher has been replaced by one that doesn't
ignoreParens().
