The new TeXLive uses font encoding TU for Unicode fonts with Xe- and LuaTeX.
The command \textquotedbl for straight quotes is no longer supported,
\textipa no longer supported with LuaTeX.
Problems with Spanish Babel and Xe/LuaTeX with 8-bit fonts lead to new errors
in some cases.
The special mode used by macros where the macro name is displayed as
grey text in a box is now one of the possible marker types for any
inset. The new code puts the macro name below the text, which means
that only the text below the current line will be moved. This makes
edition much more comfortable.
The marker_type enum has been moved from Inset to InsetMath.
A new BOX_MARKER enum value has been added and is taken care of in
afterMetricsMarkers (renamed from metricsMarkerVertical) and
drawMarkers.
The InsetMath::marker() macro now takes a BufferView pointer as
argument, so that the marker type can depend on editing state.
MathRow::metrics now makes changes to the MathRow object when needed.
The specific metrics/draw code in MathMacro has been removed and
replaced by assertions. Code in addToMathRow and marker is adapted to
reflect the cases where linearization is possible.
From now on \kern and \mkern remain as ERT as long as the length is invalid.
Fixes#10539 (regression at 10c8d51b).
The only way to produce an InsetMathKern now is via parsing (i.e. file opening
or copy-paste). This is because there has never been any sensible way to input a
valid InsetMathKern, but this is another issue.
They moved the QT_QPA_DEFAULT_PLATFORM_NAME definition to the newly
introduced qtgui-config.h header.
This fix is also necessary for cmake, but I don't know how to do it.
It would be simply a matter of using QtGui/qtgui-config.h instead
of QtCore/qconfig.h, if QtGui/qtgui-config.h exists.
Since in InsetMathNest::cursorPos we do not know what is the value of
the row element before value of a given BOX, it does not make sense to
set the cursor at a given offset from the start of the MathData
object.
Therefore here we set the cursor in the middle of the MathData object,
which unfortunately may or may not be visually centered wrt the BOX.
The best solution would be to use the MathRow data here, but
unfortunately this is not completely trivial.
This patch replaces 7917ebcc4.
Horizontal space is now added for linearized macros too.
Vertical space handling is done in a separate method.
This is in preparation for handling of 'box' macro editing mode in
MathRow.
The current version was wrong for non-English dialogs, and even for
the English one, due to the translator commands that were not removed
for calculation (as in "Formats[[output]]").
Candidate for stable.
This adds support for the chapterbib package, but also adds ways to
produce this sort of multibib with biblatex and bibtopic (which are
both incompatible with chapterbib).
File format change.
InsetMathDelim does not need markers because the delimiters are
visually enough.
CommandInset (like InsetMathRef) does have cells, but they are hidden
(only for storage). Therefore the default InsetMath::markers() method
mistakenly added markers. In practice, the markers were never active
(since the cursor cannot go into the inset), but some space was
reserved for them.
This allows to somewhat simplify the text and avoid some uses of
Paragraph (in the long term, RowPainter should not have to access
these things).
At the same time do a small cleanup to RowPainter: rename
text_metrics_ to tm_, remove pm_ and width_.
The enum values BEG_MACRO/END_MACRO and BEG_AR/END_AR are replaced by a
single BEGIN/END pair.
The MathRow code now only knows about insets and math arrays.
New hooks (before|after)(Metrics|Draw) are run by the MathRow code
as needed. They are actually also used internally by the MathMacro
code.
The gain is that most traces of explicit macro handling (and
the MathRow::Element::macro member) have been removed from MathRw.cpp.
The next step will be to extend the tokenizing process to allow for
linearizing insets other than macros.
* Convert the kerning into a proper right margin for mathnormal, mathscr and
mathcal (fonts with \fontdimen2 == 0 as per rule 17 from TeXBook).
* Simulate the fact that characters in mathnormal fonts have a 0-width left
bearing.
* Implement subscript positioning in the case of rule 17 using negative italic
correction (kerning_).
