This is triggered by selecting part of an equation under Xcb platform
(x11). Indeed, the current selection has to be sent to the X11 server
and BufferView::requestSelection() is called. Eventually
cap::grabSelection() is the function that creates this partial
MathData object.
Fixes ticket #12947.
The code that handles this special macro insertion (in
Cursor::mathMacroClose())) is very weird: it inserts the contents of
the macro _after_ the macro and later, since the macro is 'greedy', it
will eat this contents and put it in its first macro cell.
Does it make sense to you? It does not ake sense to me either. Anyway,
this is the point where one should make sure that the buffer is set.
Fixes ticket #12682.
Make sure that math insets have a proper buffer. To this end, make the
Buffer* parameter of InsetMath mandatory and fix the compilation
errors that ensue.
In order to ensure that MathData objects have a valid buffer, the
default MathData() constructor is deleted. This means that a buffer
shall be specified for each MathData object created.
This is fairly mechanical, actually. In particular, in most
InsetMathXxx cases, in MathData and in MathParser, the available
buffer_ member is used.
More specific cases:
- lyxfind.cpp takes the buffer from the Cursor
- calls to vector<MathData>::resize take an additional
MathData(buffer_) parameter. There are cases where resize actually
remove cells, and in this case clear() or even erase() have been
used.
- in InsetMathMacroTemplate, the optional parameters of the
constructors cannot be allowed anymore (a default value cannot
depend on another parameter). Therefore there a now two constructors
instead.
- in MathAutoCorrect.cpp, the MathData objects are not bound to a
buffer, so that std::nullptr is used instead.
- in MathExtern, use a buffer when one is specified, std::nulptr
instead.
Set the buffer of contents that is added to a MathData object through
MathData::insert() (both versions)
MathData::push_back()
asArray()
Also in math macros, initialize look_ with the relevant buffer.
This reduces the number of insets hat do not have a proper buffer.
See #13050 for discussion of this issue.
Now that SingleParUpdate does not always lead to a full screen update
when the height of the paragraph changes (see new behavior of
updateMatrics(bool)), it is necessary to make sure that the grey area
below the main page is always repainted.
When a buffer is reloaded, its content may remain the same, but the
memory allocation is new, so that the inset pointers in cursors are
now wrong. This requires to sanitize the cursors held by the buffer
views.
Before the biginset branch, some full metrics computation call that is
now removed probably did that as a side effect. Now we have to be more
precise.
To this effect, introduce WorkAreaManager::sanitizeCursors() and use
it in Buffer::reload().
When the width of the window did not change, computing full metrics is
not necessary in BufferView::resize(), but it is better to redraw the
screen (especially with Wayland).
Typical use cases are when using M-x to open the minibuffer or going
in and out of an equation (which shows/hides the math toolbars).
See description here:
https://marc.info/?l=lyx-devel&m=171243435229412&w=2
cutSelectionHelper did not request a metrics update when the selection
was inner to a paragraph. The new code is better, but it was not
necessary before the biginset branch because of a full metrics
computation that hid this missing case.
Annotate function LFUN_FINISHED_xxx to indicate that they do not
require a full metrics computation.
Remove an "optimization" that meant that when the cursor changed
inset, a full metrics computation was requested.
Part of bug #12297
When entering/leaving a math hull inset, a Update::Force flag was set,
in case the metrics of the inset would change because of a switch
between normal and preview representation.
When entering the inset, this code is now used only when the inset was
in preview mode.
In both cases, Update::Force is replaced with Update::SinglePar.
This requites in Text::dispatch to honor Update::SinglePar when it has
been set by some lfun, even when singleparupdate is false.
Part of bug #12297.
Entering a math inset triggers a work area reize because the math
toobars appear automatically. However, by default these toolbars are
at the bottom of the screen and their presence does not change the
typesetting of paragraphs. Therefore it is useful to avoid a call to
updateMetrics() in the case where the width of the work area did not
change.
Part of bug #12297.
The number of metrics updates when loading file and showing it in a
new work area is unreasonable.
The first avoided call to updateMetrics() was an explicit resize in
BufferView::init(). Instead, an assertion is suppressed by exiting
early BufferView::processUpdateFlags() when BufferView::ready()
returns false. This is a new method introduced to factor in some
existing tests.
Two other metrics computations are avoided by setting the enclosing
View object busy() while creating the new tab. To make this work
properly, GuiWorkArea::scheduleRedraw has to return early in this
case.
When saving an unnamed document or invoking "Save as...", call
setBusy(false) earlier so that repainting occurs correctly.
Fixes bug #12976.
With the branch-test.lyx file from #12297, loading takes forever when
previews are activated. This is because each preview element causes a
full screen metrics recomputation.
This commit just skips these calls and only does one when all previews
have been obtained. As a result, computing the previews takes 1 second
instead of 25 seconds on branch-test.lyx.
Part of bug #12297.
The most visible part of this commit is the move of part of
BufferView::updateMetrics to a new TextMetrics::updateMetrics. This
new method makes sure that metrics are known for all visible paragraphs
(starting from anchor), and that the positions of the paragraphs have
been recorded.
This method is called up to 3 times in BufferView::updateMetrics:
* unconditionally, to update all visible metrics,
* then, if the bottom of the document is visible and too high, after
updating the anchor ypos,
* and similarly if the top of the document is visible and too low.
This fixes for example the case where one jumps to Section 5.3 at the
end of Tutorial and 'scroll_below_document' is false.
Some now redundant code is removed from BufferView::scrollToCursor.
The anchor-setting code in BufferView::draw is not clearly useful, but
left here just in case. It generates a debug warning, though.
Part of bug #12297.
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.
Fixes https://www.lyx.org/trac/ticket/13048.
xcode fails with multiple error messages like this one:
----------
CMake Error in po/CMakeLists.txt:
The custom command generating

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.
The issue here is that macro templates are forbidden in InsetTabular
(why? I do not know) and Text::getStatus does not enforce that
properly. Text::insertInset is called and does nothing (because
insertion is forbidden) and yet the cursor is changed to point into
this non existent inset.
Solution:
1/ block insertion of macro templates when not allowed
2/ (additional safety) when insertion of a math macro inset failed, do
not try to set cursor inside the non-existing inset.
Additionally clarify comments.
Before this patch, all table cells had a semicolon at the beginning of their style:
<td style='; border-bottom:
This unwanted behaviour is only due to a typo in a condition when concatenating two styles: the previous code was checking the second part of the style once the first was output, instead of the first one.
In order to perform a conversion of graphic format LyX generates
a python script containing the path of the original file to convert.
While Python2 needs the file in the native encoding of the OS, in
Python3 the encoding has to strictly be how announced by the first
line of a script, in our case utf-8.
Note that there is also a vector parameter that is passed by value.
However it is modified as a local copy and I do not want to change
this now.
Spotted by coverity.
The problem is caused by removing temporary aux, etc, files while
we are in the process of exporting. As Jürgen suggested, we really
do not need to remove these files until we are preparing to export:
They are not used internally. So now we just schedule the removal
and do it then.
colswitch was checking for oldstyle instead of normalcolor
to see if we need \normalcolor, which lead to appearence
of \color{none} in some cases, but "none" is not a known
color.
Instead of displaying the complete path, display the file name
first and then the path enclosed in parenthesis.
In this way files with same name but different path can still be
distinguished and, at the same time, files with different names
but same path are more easily spotted in case the complete path
is truncated by file managers.
While it is not necessary to run validate() on insets that do not
produce output (yellow notes and disabled branches), it has to be done
for previewing, since a construct inside the inset may require some
support.
This is done in two steps:
1. in PreviewLoader::dumpPreamble, indicate that a preview is being
prepared. It is not clear why the `for_preview' boolean was not set
before.
2. in Inset(Branch|Note)::validate, always call the parent's validate
method when previewing.
It should have been possible to move the code from 2. to
InsetText::validate, but the weird code in handling
InsetNoteParams::Comment in html makes it difficult.
It is not clear whether this feature was once documented and used (it
would have been 20 years ago).
It is mostly disable now, but there was a remaining bit that is
annoying now.
I'll try to restore this later.
- Do not clear the initial selection to allow consecutive changes
(this is in line with the behavior in texted)
- Make the color changes last so that the underline is the right color
- Allow to operate on selections that span multiple cells in a grid
- Use \boldsymbol instead of \mathbf to make everything bold
This new warning in gcc 13 is annoying because it happens in certain
parts of our code where it is harmless to pass a temporary variable to
a function that returns a reference.
This patch introduces a new pair of macros,
LYX_BEGIN_MUTE_GCC_WARNING(warn) and LYX_END_MUTE_GCC_WARNING, which
can be used to define a block of code where a given GCC warning is disabled.
The macros are no-ops with compilers other than gcc, although some
compilers that pretend to be GCC make be mis-detected. The worse that
can happen AFAIU is a bunch of warnings.
The macro relies on an intimidating set of for nested macros. The goal
of these macros is to build a nested string bit by bit. Here is how it
works:
PRAGMA_IGNORE(dangling-reference)
=> PRAGMA_IGNORE_1(-Wdangling-reference)
=> PRAGMA_IGNORE_2("-Wdangling-reference")
=> PRAGMA_IGNORE_3(GCC diagnostic ignored "-Wdangling-reference")
=> _Pragma("GCC diagnostic ignored \""-Wdangling-reference\"")
The next question is: what is _Pragma() good for? Well, it is a
version of #pragma that can be used in a macro.
And finally, what are those pragmas good for? The 'push' and 'pop'
ones make changes to warnings local. The 'ignored' ones allow
to disable some warnings. And disabling -Wpragmas ensures that we do
not have a warning if we try to disable a warning that is not
supported by the compiler.
The \underbar macro is a text mode macro that can also be used
in math mode. However, when inserting it in mathed, LyX helpfully
wraps it in a \text inset. One can dissolve such text inset and
the macro would appear in math mode without any problem. But the
output routine thinks that the user is shooting itself in the
foot and tries to protect him by wrapping \underbar in the
\lyxmathsym macro, whose definition is normally added to the
preamble when an unicode character is used in math mode.
Of course, this is not the case for \underbar and a compile
error arises. The easier solution is to simply add lyxmathsym as
a requirement for \underbar in lib/symbols, but this means
that the definition of \lyxmathsym would be added even when not
necessary (because in the validation routine we miss the info
about the current mode). The correct solution is acknowledging
the dual nature of \underbar as a text-mode macro that can also
be used in math mode. Luckily the correct solution is almost as
easy as the easier one and is what is done in this commit.
Separate mangled-name tables for xhtml and latex exports.
LaTeX route should stay as it were (counter+mangled path within filenames in
temp directory)
xHTML route uses hash of path + filename only. We won't use counters because
(unlike in LaTeX export) they stay visible in final export directory and
generally change across LyX sessions.
Hash is short with collision handling because path-length limits of Windows.

Furthermore, this breaks the use of the glossary package which also

If an element is underlined in mathed by using the text properties
dialog, the changes accumulate. So, for example, to change a single
underline to a double one, one would need removing the previous
underline first. This commit allows using the text properties
dialog and simply replace an underline type with another one.
However, this works only if the underlined element is not included
in some other inset. For example, given "\uline{\text{abc}}",
selecting the 'b' and choosing a double underline produces
"\uline{\text{a\uuline{b}c}}". But, given "\text{\uline{abc}}", and
operating as before produces "\text{\uline{a}\uuline{b}\uline{c}}".
This change forces metrics computation in all cases when cursor enters
a math inset from above/below, but I do not have a better idea right now.
Fixes bug #12952.
Until now only the color of the text could be changed by using
the text properties dialog. This commit allows changing all
other properties except for strikethrough. It is possible to
also add underlining with the limitation that the changes
accumulate. This requires other work but I think that underlining
and strikethrough are not so important in mathed and can be
refined at a later time.
Fixes#12958
The proper way to do word-wise selection is to compute the words
around both the cursor and the anchor.
Note that code is uglier than it should because CursorData::normalAnchor()
returns a CursorSlice instead of a DocIterator.

to set this explicitly, as we don't know the current \parskip value.
Also improve code readability.
Error handling issues (CHECKED_RETURN)
Calling "translateString" without checking return value
(as is done elsewhere 15 out of 18 times).
AFAICS we do not need the boolean return value in these two cases.
It might happen that the selection goes away without recomputing
metrics (for example with char-forward). The added test is a bit of a
band-aid for this situation. A better solution would be to understand
better when metrics computation is triggered in mathed.
Fixes three similar warnings. One of them is the following:

When having the code preview pane open with examples/Language_Support/Mixing_Japanese_with_other_Languages_(with_CJKutf8), clicking at random on paragraphs sometimes yielded a crash: *par when par is the end of the iterator. LyX could output the whole document as DocBook without this patch and still generates the same output with it (i.e. no text is missing).
Previously, when closing font tags, only the previous character's font was used. However, if that character is deleted, it had no change of having the right font tags opened/closed. Hence, look further to compare the font of the current character to output with the font of the previously output character.
A similar patch would be required for LyXHTML, but it will come later. The main impact is that some text isn't output in XHTML (like DocBook before this patch).
The code isn't as clean as it could be. I avoided touching anything not related to DocBook, as the release of 2.4 is nearing, while leaving comments for parts to improve for the next release cycle. Given that the code compiles, there are no risks for TeX or XHTML outputs; for DocBook, less content is skipped, which is a net improvement for users.
To have a distinctive color for selected math which works in both modes
Also, link color_selectionmath with QPalette::HighlightedText, so we

Currently, selected math hull insets use Color_selectiontext when
system colors are in use. This commit implements the same behavior
for partial selection.
This is done by introducing two element types (BEGIN_SEL and END_SEL)

When it turns out that breaking a STRING row element was not
sufficient in Row::shortenIfNeeded, we still remember the shortest
width that one can obtain. Later, when we try to split a previous
element of the row, we have a better idea of how much of the row
remains after it.
To this end, change the signature of Element::splitAt to use an enum:
FIT (was: force=false), FORCE (was: force= true) and BEST_EFFORT
(split at max_width, but do not return an error if the string is too
large).

Plus several minor improvements and code cleanup
Instead of just disabling MOUSE_MOTION on inset buttons, we now register
the coordinates where the latest mouse press happens, and if that's on
the inset button we are on when releasing, we toggle the inset.
Thus, minimal unintentional mouse movements don't lead to the button not
to respond.
