Replace flag parameter for updateMetrics() by a `force' boolean. When
it is false, the method keeps the metrics of paragraphs that are still
visible in WorkArea instead of computing everything afresh. All it has
to do is update their positions.
Add code to updateMetrics() to update the value of the anchor pit/ypos
(similar to the one in draw()).
Update processUpdateFlags() to use this when update flag is ForceDraw.
Modify scrollDocView() to just change the anchor paragraph position
when the scrolling operation would re-use some of the existing
paragraphs.
The time needed to update the metrics when scrolling with mouse in the
branch-test.lyx document is now divided by 20!
Part of bug #12297.
This can make a big difference for a very large branch that contains
lots of equations.
This is complementary to the previous patch, since instead of reducing
the number of calls to updatePosCache, we make it faster.
In the same test of scrolling with mouse wheel through the
branch-test.lyx document, one finds a 23% improvement for
BufferView::updateMetrics().
Part of bug #12297.
The setting of insets positions was done twice in updateMetrics.
When one of the paragraph is a huge branch, this can be very expensive.
This leads to a 17% improvement on updateMetrics time on a scrolling test.
Part of bug #12297
The idea of single par update is to try to re-break only the paragraph
containing the cursor (if this paragraph contains insets etc.,
re-breaking will recursively descend).
The existing single paragraph update mechanism was tailored to work
only at top level. Indeed changing a paragraph nested into an inset may
lead to larger changes.
This commit tries a rather naive approach that seems to work well: we
need a full redraw if either
1/ the height has changed
or
2/ the width has changed and it was equal to the text metrics width;
the goal is to catch the case of a one-row inset that grows with
its contents, but optimize the case of typing in a short paragraph
part of a larger inset.
NOTE: if only the height has changed, then it should be
possible to update all metrics at minimal cost. However,
since this is risky, we do not try that right now.
Part of bug #12297.
if the undo element we want to add only changes stuff that was already
modified by the previous one on undo stack (in the same group), then
skip it. There is nothing to gain in adding it to the stack.
The typical use case is when doing a search and replace in a large
document that does many replacements in each paragraph. In this case,
the same paragraph would be stored repeatedly.
Fixes bug #12564.
Qt::ImAnchorRectangle has only been introduced in Qt 5.7. Since it is
used to answer a query from the IM machinery, there is no need for
it with older Qt versions.
This was completely broken: the IDs have been escaped in the LyX file
(which they absolutely shouldn't) but not in all LaTeX output (which
they should).
\ was transformed very early to \textbackslash{}, but then the following
routines escaped braces in the string, so we wrongly ended up in
\textbackslash\{\} and "\{} in the output
This is a kind of hack. This allows InsetMathHull to state that it
needs some elbow room beyond its width, in order to fit the numbering
and/or the left margin (with left alignment), which are outside of the
inset itself.
To this end, InsetMathHull::metrics() sets a value in
MetricsInfo::extrawidth and this value is added later to the width of
the row that contains the inset (when this row is tight or shorter
than the max allowed width).
Fixes bug #12320.
The previous commit introduced wrong behaviours for <>. The new code carefully escapes what needs to be escaped from LaTeX, using the now-standard XML tools (XMLStream).
In some cases (I only found numbered equations), the LaTeX output still has a bit of HTML. For numbered equations, using \tag{X} (as suggested in https://www.lyx.org/trac/ticket/13048) would require fiddling with the output. KaTeX doesn't support \label. This patch is probably the easiest and most reliable fix.

xcode fails with multiple error messages like this one:
----------
CMake Error in po/CMakeLists.txt:
The custom command generating
<build-directory>/po/LyX2.4.cat.pot
is attached to multiple targets:
translations
update-gmo
but none of these is a common dependency of the other(s). This is not
allowed by the Xcode "new build system".
The preview loader assumes all content is in the main document encoding.
As soon as content was not encodable, LyX crashed. We now check for that
and if non-encodable glyphs are found, we do not produce a preview snippet
and warn.
Ideally, the preview loader should be made aware of encoding changes, or
we should generally use utf8 for previews.
The main goal is to match TeX' behaviour. If you want stretchy operators, use InsetMathDelim / \left & \right. This patch will change the output in many files, but making the rendering much closer to that of TeX (which users should expect, due to LyX' roots in TeX).
Book authorship and authorship can be quite distinct. As far as I know, there is no standard way to represent book authorship in DocBook bibliographies.
The new approach to line breaking introduced in 71d9f6e9 is correct,
but the newly introduced min_row_wid should not be updated when the
remaining line width after a break is larger than next_width.
Swapping the two tests fixes remaining issues.
Fixes (for good?) #12899.
The display was wrong when a backing store is in use (which is the case
with Wayland). To fix this in GuiWorkArea::Private::resetScreen(), the
pixelRatio is now stored as a double instead of an int.
Concerning support for QT_SCALE_FACTOR, the existing code was wrong
because this value is already taken into account in devicePixelRatioF
for Qt > 5.6 (no fractional scaling support before that). The
situation is as follows:
Qt < 5.6 5.6 <= Qt < 6 Qt 6
devicePixelRatio int(ratio) int(ratio) ratio
devicePixelRatioF N/A ratio ratio
So it is only between Qt 5.6 and Qt 6 that devicePixelRatioF() has to
be used instead of devicePixelRatio().
QGuiApplication::devicePixelRatio() does not have a 'F' version, it
always returns the real thing.
Fixes ticket #13039.
