The setting implies that the variable external_in_tmpdir is set to false.
If a lyx-file includes external material for spreadsheet,
the conversion results are in tmpdir.
The routine doSubstitution() (insets/ExternalSupport.cpp:188) therefore
does nothing for the entry $$Contents because it uses wrong path.
Setting the res value and returning from the function at the same time
does not make sense. After reflection, it is the "return" that shall
go.
No idea what effect it had.
Intended changes:
* code is shorter and cleaner
* caret scales better with zoom when cursor_width=0: completion
indicator, l-shaped cursor...
Details:
* Rename BufferView::getPosAndHeight to getPosAndDim because ascent is
needed too and width could in the future be set depending on font.
* Get rid of rect_ in CaretWidget and record a Dimension (and y value) instead.
Remove also caret_width_ and slant_, replace rtl_ with dir.
* Make CaretWidget members public and lose the trailing _.
* change CaretWidget::update to read its parameters from current bufferview.
When validating local layout, in particular, we create a dummy text TextClass
and so are not necessarily modifying previously declared material. Hence, we
get a spurious (but harmless) "Incomplete argument definition!" warning. This
suppresses it, but to do that we need to propogate the ReadType.
Without GUI an image is not available even if it is actually cached.
In this case we load the image for obtaining its dimensions in order
to correct the clipping bounding box.
This amends 380f34a1.
This can lead to mistakes. If no buffer is required at the beginning,
it is better to pass 'nullptr' explicitly.
Fix a case of missing parameter in GuiCompleter (introduced at
f3656600). This avoids some spurious "There is no group open (creating
one)" messages.
The code in TextMetrics::completionPosAndDim is needlessly complicated.
1/ It is easier to rely directly on Text::getWord() rather than on the
helper previousWord().
2/ Using a fake row to compute completion height is overkill. A
simpler solution is proposed here.
No intended effect. These changes prepare the fix to ticket #11818.
This is mostly important for subfigures, but debugging this issue showed that InsetCaption could be slightly simplified and InsetLabel should be made a tad more robust.
This ensures that all comparisons for DocBook are made on the same normalised version of the float type. This cased a strange bug where <table> was output within <informaltable> for Linguistics Tableaux.
This lead to a quite subtle bug. The major problem is that float tags
depend on whether the LyX float has a title (formal) or nor (informal).
This information cannot be encoded in the layout format as easily as a
simple DocBookTag.
This was due to Floating::docbookTag not returning anything with the floattype_ tableau. Another issue that happened with that document is that the standard library's isspace crashed for some characters. I therefore implemented a more efficient version of the part that required it, and inlined the definition of isspace (even though that part becomes irrespective of locale, but was that feature ever used?).
Includes: semantic markup (sorry about noun: Additional.lyx uses it to mark menus; there is something better in DocBook, but it looks like the LaTeX equivalent is really for person names), boxes, info layouts.
Actually output something when list item is empty. XMLStream discarded the sequence StartTag/EndTag (nothing in between).
New-line behaviour around term in description lists.
Before, it directly wrote to the XMLStream, but it made implementation of new lines tricky. Now, it returns the XML for each sub-paragraph (delimited by new lines) as a string, so that the caller can adopt a more precise behaviour (such as in lists).
Fixes for bug #11428. Emphasis is used regularly and it is helpful to
see whether the next text will be written emphasized directly from the
cursor.
This is also implemented in MS Word and Google docs but not in
LibreWriter.
Also fixes the caret for RTL languages whose width was previously
extended into the wrong direction.
The change includes a rewrite of the cursor movement when „mac style“ is enabled and don’t change anything otherwise.
The new code for mac uses the document iterator to go forward or backward. The traversal stops at word boundaries.
If going forward the position increments until a word is reached (if not already inside) and stops at the end of the word.
If going backward it does the same in opposite direction. The cursor jumps over non-editable insets and math.
Editable (open) insets are entered and the cursor move detects word boundaries inside them.
Instead of working around crashes in update of caret geometry, only
request it as needed. The actual computation will take place just
before painting the caret.
It might be that this is overkill and that caret geometry should be
updated unconditionally. One would have to to some timing while idle to
ascertain that.
Fixes bug #11912.
The macros defined in the symbols file are only used for on-screen
representation, so that their definition should not require the use
on any latex package. Their definition should be taken into account
only when they are overridden by user macros with same name.
The rules for typesetting math differ from the rules for typesetting
text. For example, two italic 'f' chars have to be typeset more closely
than two 'o' chars in text mode, but not in math mode. Qt provides a
method that returns the distance appropriate for drawing a subsequent
character in text mode, but nothing for math mode. Typically, the
distance appropriate for drawing the next character in math mode is
the actual width span by the character, corrected by the rules of
an appendix in the TeXbook. Recently, those rules are followed more
closely in LyX but not exactly, and we have to find a way to adapt to them.
Some symbols may need more spacing around them than the width they span.
So, we use the distance suggested by Qt, unless it is less than the
width of the rectangle bounding the symbol. Before Qt 5.11 the used method
was QFontMetrics::width(), but since then it has been declared obsolete
in favor of QFontMetrics::horizontalAdvance(), whose name conveys better
its meaning.

Move InsetMacro::limits_ to InsetMacro::Private, where it should have
been from the start. This means that limits_ is now copied when the
macro is cloned.
When the fonts distributed with texlive with same family name
as ours are also managed by fontconfig, Qt is not able to
discriminate ours by the style only. In order to be sure Qt
will load our fonts, we change the foundry name from 'PfEd'
to 'LyEd' and augment the font family name with this foundry
name. This only works on *nix, because adding a foundry name
seemingly breaks things on Windows. However, this is a *nix
only problem, seemingly.
This restores the debug output as it was intended before the
introduction of the LYXERR macro that was unconditionally outputing
an end of line. This is how this output was appearing until lyx 1.5:
Looking for font family cmr10 ... got: cmr10
got it normal!
instead of as it was since lyx 1.6 and until now:
Looking for font family cmr10 ...
got: cmr10
got it
normal!
Using US english desktop language LyX's Mac OS adds some items to the view menu:
1. Show/Hide Tab Bar and
2. Enter Full Screen
These items won't work properly and it's better to hide them.
Mac OS adds two extra menu entries to the edit menu.
These menu items are:
1. Start Dictation...
2. Emoji & Symbols
Both menu items don't work with LyX.
Therefore they shouldn't be present and the new code hides them.
Both QTextLine::naturalTextWidth() and QTextLine::horizontalAdvance()
return the same value for \fint. However, examining esint10.ttf with
fontforge does not reveal any issue with the metrics. The fact that
\fint seems to be the only affected symbol might be due to its code
point, which corresponds to a space, so that maybe Qt makes some
assumptions on the metrics.
As QTextLine::naturalTextWidth() returns the width of the line that is
occupied by text, in the case of a single symbol we can obtain the
same value by using the width of the rectangle bounding the symbol.
This extra spacing was missing and is important for detecting extra
par breaks before equations (which are most of the times not wanted).
To do that, add a new member vmode to MetricsInfo which is equivalent
to LaTeX's \ifvmode (start of paragraph).
If in vmode, add the equivalent of an empty line before a display math inset.
At the same time, tweak value of \(above|below)displayskip, which was
12pt, whereas LaTeX uses 10pt in 10pt size (our reference).
Fixes bug #11891.
Fix bug where selecting in first paragraph gave an end of selection on
wrong row.
Since pm.ascent() may contain the top margin, it makes sense in
setCursorFromCoordinates() to use the ascent of the front row instead,
like was none in907f0207 for getPitAndRowNearY().
Currently tested:

Font decorations such as underline cannot be set for a whole inset
that allows paragraph breaks. This commit allows to still set the
font main properties for the whole inset but decorations are applied
to each paragraph inside the inset.
Use font switches for insets that allow paragraph breaks rather
than insets that do not inherit outer font settings. No change of
behavior is intended with respect to the current status, but this
will allow a simple and effective fix for #10263.
As this required to first generate the paragraph before outputting it if necessary, tests like XMLStream::isTagOpen no more worked properly. This also refactors table handling to get rid of that case (and make code easier to read).
This patch aims at:
1. replacing absolute paths by their hashes (do not leak directory structures)
2. not using counters anymore so that changing figures order in the document
does not lead to large number of obsolete images in export directory.
Other changes than in xHTML export of images are unintended.
Since be836909c5 the positioning of super- and subscripts
for symbol fonts has been broken because the metrics of the
font of the environment (rather than those of the symbol itself)
were used.
These are now properties of insets that can be operators :
InsetMathSymbols, InsetMathDecoration (for over/underbrace) and
InsetMathMacro (for its contents).
Each of these has a limit_ member that allows to remember a limit
forcing and a member defaultLimits() that indicates what to do in the
absence of such forcing. Moreover the write() method calls
writeLimits().
This allows to simplify the definitions of integrals in lib/symbols by
defining the integrals as macros of their "op" version, as it is done in
the style files.
Also, many hardcoded assumptions can now be removed.
The handling of LFUN_MATH_LIMITS is now done in InsetNest, which tries
successively to apply the limit change to (1) the character after
cursor, (2) the character before cursor and (3) the character at the
end of the inset (useful for script insets?)
The new code allows to define
\newcommand\int{\intop\limits}
but not
\newcommand\makelimits#1{#1\limits}
It is also possible to type explicitly \limits or \nolimits to modify
a symbol.
The goal is to reproduce the change of size of operators like \sum wen they
are in display style.
The syntax of the symbols file has been extended to allow for two code
points (like 80|88 for \sum). In this case, the second one will be
used in display style.
Update the symbols file to handle all bigops from cmex, esint, wasy and
stmaryrd.
Let the code for math symbol inset handle symbols which can change size,
using the information from the symbols file.
It did access par_metrics_[] directly because there was no non-const
parMetrics().
This patch adds one and unfriends BufferView. The code is equivalent
since in all these cases, the metrics have just been computed with
redoParagraph().
When running redoParagraph, it may happen that the ascent of the first
row changes. Since the ParagraphMetrics position is actually the
baseline of its first row, it may be necessary to update it.
Fixes bug #11601.
The 20px space on top and bottom of document have traditionally been
obtained by adding them to the ascent/descent of the first/last row.
This leads to annoyances like selections that are drawn in these
margins and issues with the nesting marker.
The change is to add the value to the ParagraphMetrics ascent/descent
only and to correct one place where the ascent of the first row may be
different from the ascent of the ParagraphMetrcs object. There may be
other places where this should be done.
Fixes bug #9545.
The 20px space on top and bottom of document have traditionally been
obtained by adding the to the ascent/descent of the first/last row.
This reads to annoyances like selections that are drawn in these
margins and issues with the nesting marker.
The change is to add the values to a separate member of the Row
object, and to add new Row::total(Ascent|Descent) methods that add the
effect of this padding.
Moreover, some methods are added to TextMetrics to simplify the
BufferView code.
Fixes bug #9545.
The old code in GuiPainter::filterColor did not work. Tricks with
colors should take place in HSV space, not RGB IMO.
Replace the code with a simpler one which maps the grayscale value
of the original color on the blend color. It works nin the case where
original color is red, but might not work as well when blend color is
not black. Time will tell.
Fixes bug #11904.
The is a fixup to commit 611df441. It seems that the wrong unicode
property was selected. It could be that both classes should be used.
Fixes bug #11900.
Add new RowFlags value CanBreakAfter, which says that the row can be
broken after the inset if needed. There is no CanBreakBefore yet,
because I do not know of an inset that needs it.
This makes screen closer to the actual behavior of insets.
Currently, only unprotected spaces and some special characters are
concerned. There may be more that need this handling.
Fixes bug #11621.
The enum DisplayType is replaced with the flags RowFlags that can be
combined. Here is the correspondence between the old DisplayType and
the new Inset::RowFlags:
DisplayType RowFLags Meaning
Inline Inline plain inline inset
-- BreakBefore row ends before this inset
-- BreakAfter the row ends after this inset
AlignCenter Display the inset is centered on its own row
AlignLeft Display | AlignLeft the inset is left-aligned on its row
AlignRight Display | AlignRight the inset is right-aligned on its row
-- RowAfter an extra row is needed after this inset
Display is just a shortcut for BreakBefore | BreakAfter.
The flags for the newline inset will be BreakAfter | RowAfter,
while the separator inset will just use BreakAfter.
This groundwork does not introduce any new feature at this point. It
aims to remve the numerous isNewLine and isSeparator all over the
code, and to eventually optional break after some insets like spaces
(see #11621).
Most display() methods are renamed to rowFlags(). Some are removed
because they returned Inline.
Now display() is only a helper function for hull insets.
Fix paragraph id in xHTML output to the pre-refactoring status.

This commit adds the mathed command \mathds that selects a
font more appropriate than \mathbb for typesetting the
mathematical symbols for the natural (N), whole numbers (Z),
rational numbers (Q), real numbers (R), complex numbers (C),
and some others.
As in the \mathbb case, only capital letters are supported,
but in addition one can also typeset a symbol often used for
representing the indicator function (\mathds{1}) and the
letters a, h, k.
Fixes bug #11887.
It turns out that the resources were mostly not used anyway. Removing
them shrinks LyX binary by ~6MB.
Only autotools have been adapted. cmake will require the same
simplification.
The automatic icons for "command-alternative", "math-insert",
"math-(big)delim" and "command" can be overriden by an explicit icon
name.
Besides that, the iconName function is refactored, and now returns an
additional bool that indicates whether the icon should be flipped.
The code that uses resources is still useless. This will be the
subject of further work.
74540c98 was a fixup of d207e85c, which avoided using inset background
as inset label background.
d207e85c introduced a background under inset labels to avoid fake bold

Hopefully, this last variation will be the right one !
This is a modern alternative for makeindex that is fully unicode-aware
and written in lua.
As opposed to xindy, it is more lightweight and actively maintained.
The program is still in a rather early stage of development, so we do
not propose this as default.
This relies on xindex 0.22 (about to be released) to function properly.

It seems that the use of zoom in determining the size of the minimal
value was a bad idea.
It still think that the situation is not very satisfying, we need a new idea.
The code was checking only for particular vertical alignment requests
in order to decide to nest a standard array into a 1x1 ams matrix.
However, also vertical lines are not possible in ams matrices.
These uses are inefficient (a loop really) and require that pit_type
is ptrdiff_t.
Instead, RandomAccesslist::constIterator is renamed to iterator_at and
a version adding a non-const iterator is added. Additionally, the
method retirns end() when position is equal to the size of the
container (see #11861).
lyx::next and lyx::prev are removed, and std::prev is used in the few
places where the code requires it (for no good reason IMO).

Before, we would continually set the selection to the empty string,
to maintain ownership. This causes problems with clipboard managers
GPaste and CopyQ. Further, in theory this should have better
performance since checking ownership should be faster than setting.
A disadvantage of this change is that the timestamp of the selection
will be old at this point in the code. However, when the selection
is requested, we put the selection contents at that point so the
selection timestamp should be accurate then. Further, the selection
contents are not accurate at this point in the code (they are just
the empty string), so it is not clear whether having an accurate
timestamp is beneficial.
Fixes#11715.
This inset allows counters to be set, reset, saved, restored, etc,
both in the LyX GUI and in the output; optionally, the effect can be
limited to the GUI. Of course, LaTeX provides means for doing all of
these things, so they could previously be done with ERT, as far as
the output is concerned. But there was no mechanism for manipulating
counters in the GUI and none for other output formats.
Keep track of nested includes and just refuse to re-enter a file
we're already in the process of handling.
There's a question whether we should do this in updateBuffer and
validate, or whether we should do it separately. For now, this seems
to work.
Other than issuing a warning on the console, now the LyX window is
raised when in single-instance mode and no files to load are specified.
In this way, the user is aware that something happened after double
clicking the program icon. To support this functionality the new lfun
window-raise has been introduced.
Actually the change is affecting only builds if
1.) Using cmake build
2.) on unix
To use it on
cygwin: one has to patch development/cygwin/lyxrc.dist.in
MacOSX: -//- development/MacOSX/lyxrc.dist.in
We need also a Windows-version
Also the compilation with automake lacks the handling of development/unix/lyxrc.dist.in
Most of the RtL icons that we provide are simply mirrors of the LtR ones.
Therefore let the code do that by default if no +rtl icon is found.
The only RtL icon left for now is for "layout Enumerate" (notice the
numbers in it).
Also remove useless getPixmap wrapper and several old bidi_xxx icons
that were forgotten in previous patch.
When the cursor in RTL text, icons for "depth-increment" or
"layout-toggle Enumerate" look wrong.
Instead of relying on the clumsy "bidi" lfun of 2898c335, this new
version relies on a new Toobar tag BidiItem that inserts an action
which can have two icons, depending on the direction of the paragraph
containing the caret (or of the direction of the UI when no file is
open).
The alternative icon has the same name as the original one, with a
"+rtl" string appended to the lfun string. The alternative icon is
only active if the file is found. The icon themes `default', `oxygen'
and `classic' have been updated accordingly.
Fixes bug #4451.
This should work on Windows, but needs test.
The changes (namely the installation directory for the dtl executables)

Fix by radical simplification of the message.
Part of bug #11777.
The ^ is interpretted as bitwise XOR, so 2^(20) evaluated to 22.
Thanks to Riki for the << trick. This way, we do not have to use
pow() and include the <cmath> header for this one expression.
As a consequence of fix e64ea357 to ticket #10797, we draw a bit too
much of the inset background outside of the inset (visible for insets
with colored background). #10797 is a ticket that triggers when the
cursor has a width larger than 1.
This patch limits the problems in two respects
* nothing is done on the left, since the cursor width only expands on
the right.
* on the right, the extra width is limited to cursor width.
Fixes bug #11786.
There is a chance that this code is still useful for Qt 4. We keep
it around just in case.
For the case of Qt 4, this commit restores the code changed in
f8e40f8a, d255339a, and d4ff3a29.
This reverts commit 438f15da21.

This reverts commit 861c6167ca.
Revert "Track whether title has been issued via OutputParams."
This reverts commit b536759c07.
There are massive complications here, and I don't have time to fix them all
right now.
Use QFontMetrics::boundingRect() instead. QFontMetrics::width() does
not actually calculate the width of the bounding box and is mostly
useful for knowing where to draw text after a string, taking into
account bearings. Indeed, it has been renamed to
QFontMetrics::horizontalAdvance().
For the code touched in this commit, we want to center a string.
Either method would likely be fine, but it is more easy to
understand exactly what QFontMetrics::boundingRect() does.
This commit does change functionality, although it should not be
noticeable.
Setting the family to "family" is already attempted above. A
different case was adapted to be this duplicate case at d4ff3a29,
but it should have just been removed.

This commit fixes the following warning from Qt 5.14:

setForeground was introduced in Qt 4.2 [1].
We have a couple of commented out uses of a setTextColor() method in
GuiDocument.cpp, but the QTextEdit::setTextColor() is not deprecated so no
change is needed.

This commit fixes a few warnings from Qt 5.14 like the following
one:
error: ‘void QComboBox::setAutoCompletion(bool)’ is deprecated: Use setCompleter() instead. [-Werror=deprecated-declarations]
We only generated setAutoCompletion() from setting the property in
the .ui files. There does not seem to be a .ui file property that
generates setCompleter(). However, the default in both Qt5 [1] and
Qt4 [2] is to enable case-insensitive autocompletion, which seems to
be the same type of autocompletion as when we were relying on
setAutoCompletion(true). Thus, we can remove the properties that set
autocomplete to true. There is only one file, SearchUi.ui, where we
were turning off the autocompletion; we now do so using
setCompleter(0) in GuiSearch::GuiSearch().

This commit fixes a couple of warnings from Qt 5.14 like the
following one:
error: ‘int QTime::restart()’ is deprecated: Use QElapsedTimer instead [-Werror=deprecated-declarations]
This commit changes two uses of QTime to QElapsedTimer, one used
only when the "files" debug flag is set, and the other for timing
whether a script (e.g., knitr) takes longer than a certain amount of
time to run.
QElapsedTimer is superior for these two use cases in that it uses a
monotonic clock if possible, and is thus more robust to certain
changes (e.g., daylight savings changes) [1]. Similarly, the commit
in Qt Base that makes this deprecation [2] mentions the following in
the commit message:
QElapsedTimer does the job better and without the DST kludges.
Note that QElapsedTimer class was introduced in Qt 4.7, so no
conditioning on Qt version is necessary.
Not all methods of QTime are deprecated and we still use some of
the non-deprecated methods in our code (e.g., to get the current
wall clock time in GuiProgress::currentTime()).

Thus a document can be viewed if it contains references to
its master, children or siblings that are being excluded via includeonly,
or viewed standalone if it contains references to its master or siblings.
Using a dialog may trigger a redraw at times where the metrics caches
have not been updated yet. To fix this, do as in paintEvent() and
abort caret blinking if there is an open undo group.
Move the decision to skip the caret painting to showCaret(), closer to
where real work happens. hideCaret () is now an alias for
showCaret(false), which allows some code refactoring.

Fixes bug #11763 (although it does not trigger on master).
This is a mode for includeonly handling that is effective and still outputs
at least mostly correct counters and references. This is intended for non-
final editing work.
File format change.
GuiInclude::initialiseParams() calls InsetCommand::string2params()
which calls InsetCommandParams::clear(), however this last function
did not reset the special "preview_" parameter. Now this parameter
is reset to false as part of clear().
The ParamData class documents (see InsetCommandParams.h) the
following:
// No parameter may be named "preview", because that is a required
// flag for all commands.
Thus, we must handle preview_ separately from the other parameters.
This commit fixes#11779.
First, we do not need to run bibtex/biber on the maintenance run, as
the necessary references will be generated on the includeonly run.
Second, exclude the master from DepTable in maintenance run, as the
master is re-checked in any case in the includeonly run, and as it will
always be detected as changed due to the \includeonly statement, which
will trigger a complete build.
More improvements to follow.
There is no need to change the cursor's position to the beginning of

QFileDialog::setConfirmOverwrite() is obsolete at least since 4.8
and QFileDialog::setOption() is available since 4.5 [1].

Fixes the following warning:
error: ‘void QWidget::getContentsMargins(int*, int*, int*, int*) const’ is deprecated: use contentsMargins() [-Werror=deprecated-declarations]
The new code also has advantages in that 'l' can be set to const and
it is more readable because it is clear that only 'l' is used.
QWidget::getContentsMargins() was deprecated in 5.14.0 [1]. and
QWidget::contentsMargins() is available since 4.6 [2].

This commit replaces qSort with std::sort to fix warnings from compiling with
Qt 5.14.1. Below is one of the warnings:
error: ‘void qSort(RandomAccessIterator, RandomAccessIterator, LessThan) [with RandomAccessIterator = QList<lyx::ColorCode>::iterator; LessT$
an = bool (*)(lyx::ColorCode, lyx::ColorCode)]’ is deprecated: Use std::sort [-Werror=deprecated-declarations]
qSort() has been deprecated since Qt 5.2. Quoting from the ChangeLog [1]:
With STL no longer being optional for building and using Qt, a number of
parts of QtAlgorithms no longer make sense, and have therefore been
deprecated. Replacements are available in the STL, and generally have
much better performance
There are some cases that require more than just a trivial substitution, but
our code does not appear to use any of those cases.
For some discussion on the differences in speed of std::sort() and
qSort(), see the following:

These are just warnings now, but will likely be errors with Qt 6:

I tested that LyX can still be built against Qt 4.8.7 with this commit.
This commit follows 24926b2e, which also fixes some deprecation warnings.

These changes fix a few instances of the following type of warning:
error: ‘void QListWidget::setItemSelected(const QListWidgetItem*, bool)’ is deprecated: Use QListWidgetItem::setSelected() instead [-Werror=deprecated-declarations]
as well as similar warnings for setItemHidden() and
setItemExpanded(). These are just warnings now, but it is planned to
remove the methods for Qt 6:
https://bugreports.qt.io/browse/QTBUG-73048
I tested that LyX can still be built against Qt 4.8.7 with this
commit. Indeed, these methods have been deprecated for a while (it
is just that QT_DEPRECATED_WARNINGS was only turned on by default
starting with 5.13.0). See, e.g.,
https://doc.qt.io/archives/qt-4.7/qlistwidget-obsolete.html
Using a dialog may trigger a redraw at times where the metrics caches
have not been updated yet. To fix this, do as in paintEvent() and
abort caret blinking if there is an open undo group.
Move the decision to skip the caret painting to showCaret(), closer to
where real work happens. hideCaret () is now an alias for
showCaret(false), which allows some code refactoring.
See also commit c7496a11b2.
Fixes bug #11763 (although it does not trigger on master).
