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 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.

Fixes bug #11912.
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.
Currently tested:
- url & doi fields for bibtex.
- all documented eprinttypes of biblatex
- absolute paths of first entry of 'file' field for jabref and kbibtex
- external script searching for author + year pdf
Additional polishing will follow.

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.
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.
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.
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.
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.
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.
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.
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.
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:
error: ‘void QTreeWidgetItem::setTextColor(int, const QColor&)’ is deprecated: Use QTreeWidgetItem::setForeground() instead [-Werror=deprecated-declarations]
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().

Using a dialog may trigger a redraw at times where the metrics caches

File format change.
Fix warnings coming from deprecations of QTextEdit::tabStopWidth()
and QFontMetrics::width(). Regarding tabStopWidth(), the ChangeLog
states the following [1]:
Introduced tabStopDistance property in QTextOption, QTextEdit and
QPlainTextEdit as replacement for the inconsistently named tabStop and
tabStopWidth properties. QTextOption::tabStop, QTextEdit::tabStopWidth and
QPlainTextEdit::tabStopWidth are now deprecated.
Note that QFontMetrics::horizontalAdvance() is what we want here, as
opposed to QFontMetrics::boundingRect(), because we want to know
where to draw the next character after the tab.

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:

I tested that LyX can still be built against Qt 4.8.7 with this

Fixes bug #11763 (although it does not trigger on master).
I've long wondered why dialogs seem to update twice when it seems
they just need to update once. It seems it was this code. But it
was only put there to deal with a problem with code in the button
controllers that was disabled in 2007! So I'm going to try removing
it. If we start seeing weird behavior with dialogs in master, then
this will be why.
In case of path names for external files containing symbolic links the real path
and the logical path name may be different for the same file or directory.
LyX is using QDir::tempPath() to create the path name of the temporary directory.
The Qt implementation is free to return the logical or the real path name here and
it happens to be different for various platforms and versions.
The most stable and clean solution is to use the real path name consistently.

There are two techniques that I know of for forcing the direction of a
string, regardlessly of whether its contents is naturally LtR, RtL or
undecided.
1/ The unicode LTR/LTR override characters. This is supposed to be the
clean way, however, it does not seem to work with Qt 5.14 (see
#11691).
2/ The undocumented QTextLayout::setFlags method. This is used
internally and allows to pass the (undocumented) flags
Qt::TextForceRightToLeft and Qt::TextForceLeftToRight. This was
used until we had issues with Qt 5.11 (see #11284).
In order to get the best of both worlds, this patch allows to enable
those two methods separately, and actually enables both at the same
time by default!
(hopefully) Fixes bug #11691.
We will replace this with a better solution
For now, only keep
- Changes::isChanged()
- Buffer::areChangesPresent(), replaced by a dummy function
Next step will be to provide a working areChangesPresent() and to
compute Inset::isChanged in updateBuffer.
This reverts commit 6d4e6aad24.
This requires to add a assertion_failed_msg handler. Take this
occasion to cleanup and uniformize the various boost.cpp files that we
have.
This adds 50k line of whatever to the source code.
Small helper lfun that makes LyX remove the aux file before doing the
next export. A bit more convenient than removing the files manually
or restarting LyX.
We tend to have insets which buffer() member is invalid. To help
debugging, this commit paints their background in red when devel-mode
is on.
To this end, a new method develMode() is added to the Painter class.
With this commit, it is easy to see that macro template do not have a
proper buffer set!
Horizontal scrolling used to be taken into account when updating caret
geometry. This is wrong since it may have changed when time comes to
draw the caret. This leads to a situation where the first apparition
of the caret is at a wrong place.
Now the extra horizontal offset is used at drawing time.
Fixes bug #11603.
The reader of CREDITS (GuiAbout.cpp) now ignores lines that start
with the number sign (#). This commit also introduces a commented
out header in CREDITS reminding any potential editor that all
changes will be overwritten by generate_contributions.py.
The provided working directory was not properly set when the underlying
process starts.
It is not clear, why only this one call to one.startscript()
needs fixing. OTOH, the other calls do not use 'Systemcall::DontWait'
as the first parameter.
When the cursor in RTL text, icons for "depth-increment" or
"layout-toggle Enumerate" look wrong.
To fix this, the lfun "bidi" is introduced. "bidi ltr func" behaves
like "func" in LTR text, but is unknown in RTL text. "bidi rtl" does
the opposite. This allows to add two icons, but only have one icon
available. When no document is available, only LTR is assumed.
To make this work, the handling of unknown functions in toolbar has
been changed so this these functions can change dynamically their
existence.
The icon themes `default', `oxygen' and `classic' have been updated
accordingly.
Fixes bug #4451.
In particular, the directory frontends/qt4 is renamed to frontends/qt.
Many configurations file have to be updated. All mentions of qt4 in
the source have been audited, and changed to qt if necessary.
The only part that has not been updated is the CMake build system.
By default, the behavior is the same as before, except that the
language of new document is not unconditionally en_US anymore.
The new checkbox "Respect OS keyboard language" (off by default)
governs this behavior.
Update prefs format to 30.
Instead of setting language from context when moving the cursor, set
it to the OS input language. This behavior will probably need to be
controlled by a preference, since not everybody changes keyboard
mapping when changing language.
This required to move BufferView::setCursorLanguage to
Cursor::setLanguageFromInput().
This bug provides two features:
1/ when a new document is created the language is set to the current
keyboard language.
2/ when keyboard is switched at OS level, the input language of
current window is changed. The language is set preferably to one of
those of the document. Ex. if the keyboard changes to en_GB but one
is typing a document in US English and Hebrew, then US English will
be selected rather that adding UK English to the list.
The implementation depends a lot on Qt. The platform status is :
* working on Windows 10
* not working with Linux (although 1/ works with Qt4); it seems that
Qt5 supports switching through ibus, but I do not know what this
means.
* not yet tested on macOS.
This addresses bugs #6450, #6247 and somehow #10514.
It is not a good idea to call caretPosAndHeight when the caret is in a
paragraph that is not in cached metrics. This can happen when not
using "cursor follows scrollbar".
This commit refactor things a bit so that testing is done in
BufferView.
This bug is not in 2.3.x.
Like with macOS, the Wayland compositor seems to require a
backingstore when doing partial updates like we do.
This extends the mechanism that has been introduced for macOS. This
has to be done at run time, not compile time.
This revives a patch by Uwe and extends it. Additional options to font
packages/fontspec can now be entered in Document Settings.
This is principally also true for TeX fonts, if the new TeXFont tag
MoreOptions is set. For the time being, I have only done this for
MinionPro, as a model and prove of concept.
Note that adding more TeXFonts requires a file format change,
respectively, and changes to tex2lyx (in the same way as I've done for
MinionPro).
This addresses #8226
With non-TeX fonts, the \inputencoding setting is overridden
by "utf8-plain" (pass-through). Keeping the old value allows
switching back to TeX fonts without the need to (re)set
the input encoding.
Also change back the GUI name of the "auto-legacy" setting
(cf. #11115).
The culprit here is the constructor QString(QByteArray const &): in
Qt4, it would interpret the byte array as latin1, and in Qt5 as utf8.
Therefore it is safer to use explicitly QString::fromUtf8 instead of
this constructor.
Several places where additionally simplified, in order to avoid some
extra conversions.
Ensure the default encoding "utf8" comes always first,
followed by other common variants.
The encodings were sorted based on the GUI name which leads to
the default setting moving from the top position in some localizations.
Prepare for languages that use CJK with TeX fonts and Polyglossia
with non-TeX fonts.
Korean is already supported by Polyglossia,
LyX support will follow (file version change).
Previously, we only included branches from the master document. This
includes those from the parent, grandparent, etc, and does so in a way
that won't crash on recursive includes.
The basic problem here is that rather than using an abstract syntax,
backend-specific param strings are produced in the listings dialog,
depending on whether listings or minted is used.
Of course this breaks if a user switches backends inbetween (s/he would
have to open and re-apply each and every listings inset!)
Do at least the most basic translations in InsetListings::latex().
A sane solution would imply the use of only one param syntax with
respective interpretation for each backend. But this would be a file
format change.
The category tag was rarely used and thus not very useful. This adds
categorization to most modules (the rest will follow) and uses the
\DeclareCategory tag we use in layouts rather than the extra syntax
we used in modules. Categories are now added to the po files and
translated.
Note that this is work in progress: the current categories are still
subject to change.
The ultimate goal of this is to sort the modules in the GUI by category
as we do with layouts, examples and templates (and add a filter to search
for specific modules)
As it is now (with the many modules we accumulated), the module selector
is not really usable anymore. If you don't happen to know how exactly a
module is named, selecting a module is really a PITA.
The idea is simple: we insert a pre-formatted table (with a given border
style currently, but other attributes are possible as well) via file-insert
and scale it then to the requested size.
We need three sizes (1x1, 1x2 and 1x3) to generate all sizes properly (due
to border specifications).
Currently, these styles can only be accessed via lfun tabular-style-insert
and the Tabular Create dialog.
My plan is to add a buffer param to set a default style (#9901) which then
also is respected by the toolbar button and probably a layout tag to let
classes specify a default style (#8360).
Attempt to save the template in the appropriate language subfolder of
the user template directory (and propose to create it if it doesn't exist
yet).
That way, user-generated templates (1.) get the correct language attribution
in the lyxfiles dialog and (2.) users can easily generate different
language versions of a template.
Now only the languages available for the selected file are displayed.
By default, LyX pre-selects the GUI language (and falls back to English
if this is not available). Once another language has been selected by
the user, this one is preferred before the GUI language (and the English
fallback).
This seems to be necessary on windows, where math editing can get very
slow. Note that other methods like rbearing already use a cache.
In the future all these caches for single characters shall be unified.
This lists all respective files from user, build and system directory
in a structured way and thus allows for easier access to them.
Fixes: #2396, #6861
Fixes: #11508
Now there is the opposite case which needs to be addressed:
If no translation is available for a shortcut in a non-latin-scripted
document, we need to switch the language to English.
This commit removes the adhoc code in GuiPrefs and moves it to LyXRC,
so that it triggers in every preference change.
The code has also been updated to trigger on more variables, e.g.
font_*_foundry.
Note that the actual function that are called have not been changed
(addPreviews and LFUN_SCREEN_FONT_UPDATE), although there are doubts
that they behave as needed (see FIXMEs).
Fixes bug #11498.
Currently, our computation of row height is not completely standard:
* we ignore completely the QFontMetrics::leading() parameter
* we add arbitrarily 2 hardcoded pixels to the height.
This patch reverses these two choices, which leads to
* slightly larger spacing for MinionPro (which has a big leading).
* an additional spacing of 20% font height that depends on dpi and zoom.
Visual inspection with LibreOffice seems to imply that it disregards
the font leading but uses a interline which is 20% larger than the
font height.
Looks like an accidental commit.

move our stuff off the Q* namespace

That's all a rename, basically. The original file, QGraphicsUi.h, was commited at 12e5a52b92, and it was empty then, too.
For some reason, adding a LTR/RTL Override unicode character before a
MinionPro string increases the ascent of the line.
This creates vertical offset issues when painting if the ascent used
as reference is the one of the font. Use the QTextLine ascent instead
for better results.
This is a followup to 1bed76e2a.
Fixes (reopened) ticket #11284.
Eventually, all overridden virtual methods should be marked properly.
Currently, clang only warns about those in classes that already use
override in at least one place (which was the case dor GuiApplication).
When blinking the caret, it looks like a cool idea to only update the
small rectangle containing the caret. Actually it is an awful idea, since
the paint event will paint some rows, and these rows will not be
properly painted outside of the small rectangle. Unfortunately, the
painter will skip those "painted" rows on next paint events.
This leads to painting errors that depend on the ordering of "real"
and "caret" paint events. This is the reason why they only appeared
with split screens.
Quote of the day: ``The real problem is that programmers have spent far
too much time worrying about efficiency in the wrong places and at the
wrong times; premature optimization is the root of all evil (or at
least most of it) in programming.''

Fixes bug #11354.
We need to load the master document before applying the params, since
otherwise the TOC reset (and other things) happen before the master
has been loaded (and set as parent).
The last 20 applications are saved now and accessible both via the lfun
(textstyle-apply n) and the toolbar (via button menu)
Fixes: #7133
This also changes the default icon and toolbar position of the action,
as requested in #11427
