The only goal is to improve code readability: this enum class is strictly equivalent to a Boolean, with the same meaning as the previous is_xhtml arguments (arbitrary choice).
In several range-based for loops, implicit copies are made. Remove
that when possible, and try to shut converity up otherwise.

When unbinding a shortcut, it may happen that the exact definition of
the request is not known. A typical example it Tab, which is bound to
a complex command sequence.
In this case it is convenient to use the syntax
\unbind "Tab" "*"
To make this word, the special "*" value is translated to the
FuncRequest::unknown lfun and this value is considered specially in
several places.
This code was triggering the following warnings:

This commit amends a65e12d6.
Time will tell whether this is too expensive (because most equations
after this on will change too, unless equations are numbered by
section).
Related to bug #11535.
This patch simplifies and fixes the generation of previews with
numbering. Instead of saving the counter values (which is complicated
and error prone), the \thequation macro is set to the numbers_ string
which has been computed by updateBuffer for screen display.
Harcoding the number in the formula means that two equations with
different numbers have different previews, which is the subject of the
bug.
The special code for saving counters in updateBuffer and outputing
them in preparePreview from 645f9fdf (ticket #6894) is removed and
replaced by this simpler approach.
This fixes ticket #11535.
The module subequation allows to number equations in the "Subfigure"
inset to be numbered (1a), (1b), (1c), etc.
To implement this on screen, we need to redefine temporarily the
"equation" counter to use this different numbering.
To this end, implement Counters::copy method that can be used to
backup full counter definitions.

The layout from the paste content is adopted only if
- the paragraph is empty (ie. empty after the selection has been
erased) and Standard or Plain Layout, or
- empty and multiple lines are pasted, or
- multiple lines are pasted at the beginning of a paragraph
As for what other applications do:
- MS Word decides the adoption of a layout depending on whether the end of line
character is copied
- Libre Writer adopts the paste content layout only if the paragraph is empty
(otherwise it makes *all* pasted paragraph the target layout)
In LyX, as in Libre Writer, one cannot copy the end of line character by
selecting a single line. However, the Libre Writer solution is problematic
because one always has to make sure that a paragraph is in Standard layout if
one wants to paste several lines with their source layout. The implemented
behaviour differs from Libre Writer in that the source format is kept when end
of line characters are pasted, i.e. several lines are pasted, and hence does
what MS Word does in that situation.
Fix for bug #11023: Copy and paste from one list into another often leads to
undesired result.
Introduce the new FileName method ensureExtension, which does the following:
* if the extension is already correct (in a case-insensitive way), do nothing.
* if it is not correct, add the extension to the file name.
This is different from changeExtension that will fail in a case where
the file contains dots, but not a real extension, like newfile2.1.
Use this new method in renameBuffer() and exportBufferAs().
Fixes bug #11008.
This requires to add a parameter to GuiToolbar::addItem so that it is
possble to make a difference between toolbar buttons and menu items.
The long-term solution is to rely on the menu backend for such things.
Fixes bug #12004.
There are several small parts that are needed here:
* Implement LayoutModuleList::asString() that returns a comma-separated
list of modules.
* in Converter::convert(), handle the new tokens $$c for the current
textclass and $$m for the list of modules.
* in Buffer::importFile(), pass the current buffer as parameter instead
of nullptr.
* in pasteClipboardText(), copy the parameters of the current buffer to
the internal one used for importation, so that the textclass and
modules information is available to convert().
* finally, modify configure.py to pass "-c $$c -m $$m" to tex2lyx for
the latexclipoard->lyx converter.
Fixes bug #11312.
In Advanced Find and Replace, Tab can be used to move the focus from
Search field to the replace field. This is inconvenient when Tab has
another use, like completion.
To fix this, check that the function bound to Tab is disabled before switching focus.
The same is done for BackTab.
Fixes bug #11114.
The removal of duplicates is done in LastCommandsSection::add and uses
the erase-remove idiom for performance.
Most of the patch is a cleanup of GuiCommandBuffer:
* remove history_ member, that was a copy of the session lastcommands
vector. Use instead a wrapper history() around it and a addHistory
wrapper for adding new entries.
* Make sure that there is only one place where commands are added to
history. The code used to maintain a list for interactive editing,
and a list for saving the session. They could be different in terms
of leading/trailing spaces.
* [unrelated] remove command_ member, which is just a copy of
LyXAction list of commmands. Use directly lyxaction instead.
In mathed it is assumed that a labeled line is also implicitly numbered.
However, latex allows to label an equation without numbering it.
The label is then assigned the value of a nearby numbered one.
This commit drops the above mathed assumption in order to allow to import
valid latex code with a labeled but not numbered equation line.
The screen representation omits the line number and encloses the label
in square brackets for further differentiation. However, it is still not
possible to label an equation without numbering it using the GUI.
The aliases are defined by a file in the (system or user) image
directory. The format is pretty simple: each line is like
<str1> <str2>
Where every instance of <str1> will be replaced with <str2>.
Fixes bug #12509.
Adding this particular line created bad redraw interactions. See
thread on lyx-devel here:
https://marc.info/?l=lyx-devel&m=165648365808777&w=2
The code is reorganized a bit:
- the part of updateGUI() that (en|dis)abled elements is not moved to
updateBottons ; the rest is renamed updateWorkAreas()
- only updateButtons is called now in eventFilter
- finally the recursion curse is fixed now in updateWorkAreas() by
setting the old_buffer value _before_ calling copy_params. This
avoid recursion if some bad update were to happen again.
When changing the document class, the message "Converting document to
new document class..." is shown in minibuffer. This message leads to
weird GUI update interactions with the FindAndReplace panel, and
ultimately infinite loops. It would only be useful if the conversion
took a long time.
See this thread for rreference:
https://marc.info/?l=lyx-devel&m=165648365808777&w=2
Therefore, just remove it.
This important part is the last point, the rest is what is needed to
make it happen.
* implement (FindAndReplace|FindAndReplaceWidget)::hasWorkArea, that
tell whether a work area is own by the advanced find & replace
widget.
* factor out method find() from GuiView::findOrBuild.
* implement GuiView::hasVisibleWorkArea, that tells whether a workarea
is visible in the view (current tab in a split or adv. f&r
workarea).
* Finally, in TocWidget::sendDispatch, change the current workarea
temporarily to the document workarea before dispatching the
function. The code tries to be as careful as possible to handle all
cases. The future will tell whether it is good enough.
When the commit string from the inputMethodEvent can be interpreted as
characters bound to some action, dispatch this action instead of
inserting the string.
This is useful on an international keyboard, when diaresis+space gives
a plain double quote. It is better in this case to enter a smart
quote.

Fix for bug #12547.
- "Interword" becomes "Normal"
- "Protected" becomes "Non-Breaking"
Plus a minor fixes to the "Horizontal Space Settings" dialog:
- Indicate that when "Non-Breaking" is disabled, the space will be non-breaking
In FindAdv we use Qt to interpret regular expressions.
Regex uses for instance '\w', '\d' etc.
'\d' finds not just '0-9' but also e.g. '߂' (Nko Digit Two: U+07c2)
'\w' includes also such numbers.
ATM, only FindAdv uses this function.
In this case we skip the undesired word-characters before starting the search.
There are still some inconsistencies between LyX and Qt of 'what counts as a word-character',
but too hard to resolve.
Since the element 'match_len' in class MatchResult is an integer,
the check 'if (!match(...).match_len))' is changed to
'if (match(...).match_len) <= 0)'
1.) The type of variable at_begin changes from bool to enum matchType
true -> MatchStringAdv::MatchFromStart,
false -> MatchStringAdv::MatchAnyPlace
2.) discard default parameter-values of
MatchStringAdv::operator()
MatchStringAdv::findAux()
1.) Changed arrays dept and closes to vector-type because of runtime error in UserGuide.lyx
with a big paragraph (size > 8900 chars) contained too many opening parentheses
2.) Removed one creation 'textcyrillic'-key because it is later anyway created
3.) Most important (thanks to Scott who found the failure)
Move the check if the found string really is part of MATH to
the relevant place.
Without this change the search using 'Search only in maths' will fail miserably.
When implementing multi-row string breaking, an extra createLine()
statement, which made sense in the original code, was kept by mistake.
This basically made the mechanism ineffective, because it created one
row with the correct length, plus a second one with all the remaining
text, which would have to be itself broken. This went undetected
because the display is still correct.
Additionally, this issue polluted the break cache to the extent that
the hit rate could be 0%.
Together, these two effects created a major slowdown with a document
containing a single ~30000 characters paragraph.
Fixes bug #12534.
When toggleFree is called without a selection, the only result is to
change the cursor currentfont.
In the other cases (selection or implicit selection), we want to reset
the cursor font from the text font.
Fixes bug #12518.
To handle this case, we use '\lyxdollar' string instead.
Also try to handle '\n' in the docstring directly instead in the
string already converted to utf8.
(The utf8-version is still there, but commented out)
If the searched area contains deleted parts, there may be more closing
as opening parentheses in latex output. We have to remove them before
further processing.
Using the new inline statements
find_effective(), find_with_non_output(), find_with_deleted(),
find_set_feature(), find_add_feature() and find_clean_features()
makes the code a slightly better readable.
This lfun (like several others) does not work with multicell
selection. Disable the lfun in this this case for now, until a nice
solution is found.
Fixes bug #12530.
Also fix a thinko in interpreting the found values.
The match_len describes the length of the second regex field,
while matchend is the length of the search field 0.
This happens when the cursor goes into a deeper inset, since
selectWord() was called on the wrong Text object.
Additionally, fix the new word selection when cursor goes before
existing selection.
Fixes bug #12529.
DocBook comes in another commit, as the modifications are not required to keep the code compilable.
A semicolon is no more used between an index term and the places it appears, because some languages need a space before it and others not: this wasn't handled at all. With a dash, this problem disappears.
We are removing leading values from the start of string, so
the size of removed data was wrong because s.find() could find
a position inside the leading part.
Problem occured if
1.) not using regex and
2.) search without format and
3.) the search pattern ended with '}'.
then this last char '}' in the search pattern was discarded.
With the debug-level 'find' there are now less output.
The original output can be received now with debig-level 'findverbose'
Also constructions like
LYXERR(Debug::FIND|Debug::FINDVERBOSE, "...");
are now possible.
This adds native macros for subindexes (!level), |see and |seealso

1/ put cusror in some display inset
2/ use shift-left until the cursor exits the inset
3/ see how the selection extends on the right.
This is not really a selection drawing bug, but rather the fact that
the anchor will be normalized to the first position after the inset,
which is in the next row.
This can be avoided by using the boundary property.
See discussion in bug #12520.
Difficult to decide, when to remove the sequence '%\n'.
The sequence is OK for latex output as a command separator,
but must be removed in searched string.
Alas, not all occurences are wrong. Sigh.
It is not a good idea to contruct a QChar from a char_type that is
really 32bits.
Use lyx::isSpace, which already catters for this case.
Since this code does not depend on qt anymore, move it to
support::countExpanders.
Get rid of Row::countSeparators, which is not used anymore.
Fixes bug #12519.
The functionality was mentioned, but it seems worth it to give the
command explicitly, so it is seen how "Branch:<branch name>" is used
to refer to the specific branch with name <branch name>.
Additionally, tweak a phrase in doc for buffer-forall.
In some situation the macros are not used with their unicode
representation. For instance all greek characters are used
as \alpha, \beta, ... in the latex output.
For the search it is more convenient to use the corresponding UTF-8 codes.
Wrong behaviour before this commit:
Open new lyx-file
insert
unicode-insert 0x025c 0x1d08
Open adv-find dialog
search for unicode 0x025c OK
search for unicode 0x1d08 OK
search with regex for unicode 0x025c OK
search with regex for unicode 0x1d08 ==> NOT OK (because we are searching for \textrevepsilon
and this was mapped to 0x025c

1. Start a new document.
2. Start a math inset and inside put "1+2".
3. Put the cursor to the right of "+".
4. Press <Shift> + L three times. This will select the entire math inset
(as expected).
5. Press <Shift> + R.
Before 503c7c16, the selection inside the math inset was preserved.
After 503c7c16, it is lost.
The problem is that InsetMathNest does too much for our needs and
resets the anchor (why, I do not know). Therefore, it is better to
duplicate the code.
These are just annoying. Note that the language mark cannot currently
be specified in a layout file, but it is not clear that there is a
need for that. Therefore I used the simple and hackish way.
This is actually a generic InsetInfo issue:
1/ the contents of the inset is computed in updateBuffer, so that it
is available for drawing but also for latex output (think batch
export). When it is called, it deletes the existing inner paragraph
and replaces it by a new one
2/ metrics build a new Row object that represents to paragraph
3/ draw() relies on this information
Now, imagine that updateBuffer() is called after metrics(). This can
happen for many reasons, and does happen here (display a shortcut info
and change the shortcut file from cua to emacs).
This problem has been here forever, but is only visible now that the
(experimental) bookmark display code needs to read the underlying
paragraph id.
The solution is to compute the inset contents at metrics time. This
is done by moving the relevant code to a new standalone build() method
that is called in metrics() but also in latex().
Except for dvi/ps output chain for which this trick was meant.
Also, issue an error message in this case. This is analogous to
the other output flavors now.
This is important for commands like !`, that are equivalent to \textexclamdown. However, ! is matched earlier, because the logic works with prefixes, hence the output doesn't make sense.
This avoid a crash when doing
command-sequence inset-forall Caption char-delete-forward; statistics; undo
in the user guide when a malformed selection is created.
The selection happens here because char-delete-forward will select the
caption instead of deleting it if the "force" parameter is not given.
This is a poor API IMO, it is the plain <del> action that should use a
special parameter.
Fix for bug #12456.
The labels are transmitted from Buffer to GuiRef by reference of refs_
in the getLabelList function. Previously, only one string was
transmitted. But I needed both the formatted string, e.g. "x enu:test"
or "Missing: enu:test", as well as the plain label, e.g. "enu:test".
The former is for the list of labels to choose from in GuiRef and the
latter for the label as shown in the line edit that contains the plain
label in order to create a new reference from it. Transmitting both is
what the pair achieves.
It does not make sense to issue the index processor before the
pagination is fixed. Particularly, if (classic) BibTeX is run,
we need one or more extra LaTeX runs after that before issuing
the index processor, since the citation labels and references are
only expanded then, which might change pagination. As a consequence,
we ended up in wrong index references.
This fixes a 16 year old bug report.
The minimal vamue is set to 10%, let's set the max to 1000%. This
avoids crashes when characters are too large.
The code is refactored to be more compact and the tests are more precise.
Fixes bug #12452.
Display manually set itemize symbols and their size in the work area.
Fix for bug #2277.
Also fixes a problem with document settings changed() not correctly emitted.
Before this patch, LyX would forcibly create an <abstract> tag even when there was no abstract in the document; this behaviour is sometimes desirable, but not when the abstract only contains comments (that's not valid DocBook: there must be a paragraph or assimilated within the abstract).
Inside a math inset when completing macro names, it could lead to crashes.
Note that this processUpdateFlags is present when outside of this if() branch.
When inserting inset over a selection, the layout is transferred if
the inset covers full paragraphs.
This is not the right policy in the case of environments. Until proper
code is written and tested, limit ourselves to command layouts.
Fixes bug #12251.
Typical example is a Labeling layout which label is an inline equation
larger than the screen. Before this commit, the row would not get
broken at all.
Two parts in the patch:
1/ when breaking the row in shortenIfNeeded, mark the last element as
AlwaysBreakAfter instead of BreakAfter, in case the next element is
NoBreakBefore.
2/ when nothing could be done, as last resort keep the first element
of the row only.
Prevent the return of impossible values for 'enum flags'.
For instance the result of '~Update::Force' at src/BufferView.cpp:3025 without this patch
is '4294967293'.
The string that Qt sees is not the original string, since we add
zero-width nonbreaking spaces around it, plus an override character to
force rendering direction. This means that translating positions
between these two representation can be a bit tricky.
We use a max(foo, 0) here to make sure that our intermediate
computation is postive.
Fixes part of bug #12452.
Setting sufficiently high value allows to use
ColorCode enums for new up to 32000 branch insets.

"'ColorCode' ... src/Color.cpp:435:10: runtime error:

It is not a good idea to take into account the horizontal scrolling
that may have happened. For example, this leads to display glitches
when a Description label is larger than text width.
This explains why SingleParUpdate strategy did not work with home/end
on a long row.
The spacing of Labeling, Description and friends shall be computed
when breaking the row, not when tokenizing it. Indeed, this is the
right place to determine its correct value.
To this end add a new MARGINSPACE row element type.
This allows to remove TextMetrics::labelEnd, which is not used anymore.
When a string is broken at the margin by the Qt algorithm, the space
at which breaking occurred is automatically skipped in width
computation. However, the ending space of the string is taken into
account and is visible for example at paragraph end.
When the trailing space is followed by a displayed inset, then the
space should be skipped too, which means that the width of the last
row element has to be recomputed. For the sake of performance, the
width of the element without trailing spaces is computed in advance in
FontMetrics::breakString.
This "no space" width will be used when trimming a row element of its trailing
spaces instead of the original one.
Additionally, do not trim trailing spaces when the row is flushed.
Fixes bug #12449.
The search widget triggers a showEvent() in updateTitle() leading to setting the focus to the default push button.
The check in updateTitle() for the need to restore the title avoids superfluous show events and avoids the unwanted focus change.
This ensures that we use a consistent Python interpreter in LyX.
$${python} is replaced by the Python version found.
Users can apply this in preferences and use the same version defined by
LyX.
An inset that resets its font (like Footnote) does not care at all
about enclosing font. Therefore the real starting point is the class
default font. This avoid cases where the footnote contents is forced
to \normalsize.
It turns out that the Greyedout note inset, did inherit font but was
declared as not doing it. This commmit changes the definition by
adding \normalfont\normalsize so that no inheritance happens.
Note that actually \normalfont resets everything but the font size.
This does not matter for footnote (which has its own font size) and
greyedout (which is fixed now), but may matter elsewhere. Also, I do
not know what the situation with HTML is.
We could not figure out the root issue, or at least not to the point
where we felt changing this code considering we could not trigger
any bug from a user perspective.
For now, we just add a comment in the code.
For more information, see our ML discussion here:
https://www.mail-archive.com/search?l=mid&q=20211227113249.53bf5a63%40admin1-desktop
This catches the case where the caption only contains a comment, as in export/export/latex/lyxbugs-resolved/cprotect/9313-comment-in-figure-float-caption. No duplicate work is performed to ensure the same level of performance as before.
The checkbox is hidden when backing store is enforced (wayland,
macOS). In practice, only X11 and Windows users will see it ; I only
have evidence of X11 people needing it, I can hide it for Windows
users too if necessary.
Fixes bug #12119.
LyX relies on a a backing store to draw when running under macOS or
Wayland, because Qt arbitrarily overwrites parts of the workarea
before we paint (and we paint only the parts that need to be painted).
However it seems that this is also necessary on X11 when the WM theme
is translucid. Since there is no way that I know of to detect this
situation, this patch adds a LyXRC setting to manually select this
drawing strategy.
Note that using a backing store is not always a good solution, since
this disables subpixel aliasing.
At this point there is no UI for the variable.
Fixes bug #12119
The default in the .ui is not considered in
GuiSearchWidget::restoreSession(), which sets a hard-coded default
if the stored setting is not found in the session file.
I'll start an ML discussion for whether the code in restoreSession()
should use the ui's default if the setting is not found in the
session.
For some reason, Qt can break strings before the first character
(although we try to prevent that). The code was not prepared to that,
now it is.
Remove a forgotten debug statement.
When a selection extends on more than a row, the space between the two
rows should always be painted in full. Otherwise, with layouts like
Chapter, the "Chapter" label may seem selected in part.
Increase the maximal size of the breakString cache (to compute where
to break lines) from 512kB to 10MB. This has a big impact of cache
hits on large file like the example in #12297, which is now 99%. On
this example the time taken by breakString decreases from 33.5us to
2.4us.
The string width cache has been increased fro 512kB to 1MB, but this
does not make such a big difference.
Additionally, comments and variable names have been improved.
Related to bug #12297.
Add new row flags Flush and FlushBefore to let insets indicate whether
they cause flushing of current row (eg. newline) or of previous row
(e.g. display insets).
Replace FontMetrics::breakAt, which returned the next break point,
with FontMetrics::breakString, which returns a vector of break points.
To this end, an additional parameter gives the available width for
next rows.
Rename various variables and methods accordingly. Factor the code in
breakString_helper to be more manageable.
Adapt Row::Element::splitAt to return a bool on sucess and provide
remaining row elements in a vector. The width noted above has been
added as parameters.
Rename the helper function splitFrom to moveElements and rewrite the
code to be more efficient.
Remove type of row element INVALID, which is not needed anymore.
The code in TextMetrics::breakParagraph is now much simpler.
In Row::finalize, remove the code that computed inconditionnally the
current element size, and make sure that this width will be computed
in all code paths of Row::Element::splitAt.
In TextMetrics::breakParagraph, get rid of the fragile `pos' local
variable, which was not correctly updated. Rely on the endpos of the
last element in row instead.
Rewrite cleanupRow to rely on the endpos of last the row element to
set row endpos, instead of a `pos' parameter.
Instead of having breakParagraph decide when breaking a row is
necessary, let Row::shortenIfNeeded set the row_flag of the last
element to request a row break. This was already done in splitAt.
This is in preparation of splitAt splitting in more than two elements.
Move to Row::Element::rtrim the code in Row::shortenIfNeeded that
removes trailing spaces from last element in row, so that it can be
called when actually breaking a row.
Fixes bug found by Kornel.
In this case, the extra element returned should empty but valid. The
row flag BreakAfter is set to indicate that we have a break there
(this principle will be used more generally in a forthcoming commit).
To detect that we cut at the trailing space, it is necessary to rely
on the difference between QTextLine::horizontalAdvance() and
QTextLine::naturalTextWidth() when the flag
QTextOption::IncludeTrailingSpaces is used: the trailing space is
taken into account in the later, but not in the former.
Somme comments have been added to make code intent clearer.
At least with Qt 4.8.7 on Ubuntu 16.04, QTextLine::lineWidth() can
return a bogus value, at least with Courier font. One hypothesis is
that the invisible characters that we use in breakAt_helper are given
a non-null width.
Work around it, although the exact bug has not been pinpointed.
Change semantics of Row::shortenIfNeeded: instead of breaking the row
and returning a boolean, it returns the list of row elements that have
been removed (or broken) from the row. The logic of the method remains
the same.
Use shortenIfNeeded in breakParagraph. This was the last missing block.
Remove Row::breakAt and the old breakRow. Only bugs remain now :)
To this end, add the helper function needsRowBreak which computes the
effect of two consecutive row flags. This function implements the
priorities described in RowFlags.h.
This function is called with the relevant flags, or NoBreak* when at
boundaries and updates need_new_row.
Some common code is factored in a new cleanupRow() helper.
Remove the code that computed the width every 30 characters (yay!).
Make sure that finalizeLast() is called after inserting a row element in
a row in breakParagraph.
Still many features missing:
- handle insets that break rows (display math, newline, ...)
- handle rows that are too long by replacing the single call to
breakAt with a call to a reworked Row::shortenIfNeeded.
- some easy things at the end of breakRow (bidi text, etc.).
Move the enum definition RowFlags in its own include file, to avoid
loading Inset.h. Document it more thoroughly.
Rename RowAfter to AlwaysBreakAfter.
Add CanBreakInside (rows that can be themselves broken). This allow to
differentiate elements before bodyPos() and allows to remove a
parameter to shortenIfNeeded().
Make the Inset::rowFlags() method return int instead of RowFlags, as
should be done for all the bitwise flags. Remove the hand-made bitwise
operators.
Set R::E::row_flags when creating elements.
* INSET elements use the inset's rowFLags();
* virtual element forbid breaking before them, and inherit the *After
flags from the previous element of the row;
* STRING elements usr CanBreakInside, except before bodyPos.
More stuff may be added later.
This contains large parts of breakRow, but creates a unique row for the paragraph.
The parts taken or not in redoParagraph are annotated.
The new method is not used yet.
Move declaration of RowList to Row.h
Move initialization of POD members of Row and Row::Element to declaration.
Make method isVirtual() depend on type.
Add new row element type INVALID and method isValid()
Make methods R::E::left/right_pos inline.
Add method R::E::splitAt() that returns an element containing the
remaining stuff, or an invalid element if nothing was split. breakAt
is now a simple wrapper around this function.
Add method R::push_back().
Since we intend to break the row element in two, it is not good to
truncate the string too early.
Moreover, the row element width is now set at this point, even if no
breaking occurs.
When inserting € in a math cell, it is put in a text inset and the
cursor leaves the inset. However, inserting ¤ then leads to
\text{€}\text{¤}.
Therefore, try to see if there is a previous \text inset that can be
recycled and insert the new inset there in this case, leading to
\text{€¤}.
Fixes bug #11979.
This allows to simplify the code in Lexer and to remove the dependency
on Formats class.
As a consequence, a pair of dummy definitions of isZippedFile can be removed.
Some new parskip possibilities had been added, but the check for
custom length index had not bee updated.
This code is very fragile.
Related to bug #10968.
The code that determine whether an InsetArgument is passThru is
complex and lives in updateBuffer.
This patch factors out the code in a new init method and calls it also
in doInsetInsert when inserting a InsetArgument.
Fixes bug #12143.
Rather than that, keep it with a warning that it is not available.
Fallback procedure (which maintains security measures) is done in
the conversion step.
This prevents document properties being silently changed on sharing.
The QWinMime class has been removed in Qt6 but the functionality
is still present. However, one has to allow inclusion of private
headers and register the mime handling to the QWindowsApplication
native interface.
Those checks might not be needed, but it's not self obvious from
the surrounding code. Because we already experienced crash from
similar change (cf 1c1c83eced), let's be prudent here.
If you know that these pointers can't be null from broader context
feel free to remove the guards.
Introduced by 24926b2e23, fix 104fdcc9be not backported
but now fixed by 1c1c83eced in 2.3.

Clang 12 (at least) misses the fact that tag is always initialized,
because the if/else sequence does cover all cases.
Initialize the variable although it is not required. It does not hurt
at least.
The code is written in such a way that the elements are searched
several times. This can be expensive when there are a lots of insets
in the document.
Concerning the sanity checks, they are now conditionned on the
presence of assertion.
Related to bug #12297.
Add parameter 'force' to scrollToCursor(...) to avoid the case where the
cursor is not set to top because it is already visible on screen.
Change screen offset in this method so that the paragraph is really at
the top of the screen. This part may cause unforeseen issues and needs care.
gotoInset: use the new force flag and do not trigger a redraw.
Instead, return a boolean telling whether redraw is needed.
In the code that use it, set an update flag instead of the extra redraw.
In the handling of paragraph-goto, also set the update flag instead of
triggering a repaint.
Remove Bufferview::scrollToCursor(), which was equivalent to showCursor().
Fixes bug #10425.
Lyx crashes on export to pdf if used with sanitizer set to 'unspecified'.
Crash found by Scott.
Given that if we export without GUI, there is some weirdness here though.
1.) Why does lyx not crash if not using '-fsanitize' compile-option
2.) Why is export to pdf dependent on the screen-resolution
This fixes two performance issues and improves the performance of
TextMetrics::redoParagraph by 15% in a workload that uses the cache a
lot. The difference will be much less when the cache is not used much.
1/ repetion of the hash code computation
The code
if (cache.contains(key))
result = cache[key]:
is not efficient, since qHash(key) has to be computed twice.
To fix this a new Cache::object_str() method is added, which allows
if (auto * obj = cache.object(key))
result = *obj;
2/ code of has code computation
Instead of using a verbose string that is complicated to build as
key, new key structs BreakAtKey and TextLayoutKey are introduced,
along with the relevant qHash() implementation.
IGNORE is a typical placeholder for tags that should not be output, along with NONE. At some point, we should check if both are required, or if NONE is enough…
Initially Qt5 modifier handling was broken. Therefore a workaround was introduced.
This workaround broke the LyX modifier handling with swap of Command-Control-key disabled.
The change disables the hack to get the correct behavior in LyX.
We now use a new variable, "wrap", to track if a wrap should be
done, which is true either if "auto_wrap" is true or if the user
chooses to wrap in the dialog.
This preserves the meaning of the "auto_wrap" variable and also
removes the confusion of why the previous code of
if (!auto_wrap) {
...
}
if (auto_wrap) {
did not use an "else" instead of the second "if".
No change in functionality.
Does not change much, but Coverity complains about it. Let's see if
this allows Inset's child classes to grow their own move constructor.
Also some whitespace.
This requires the introduction of the booleans selected_left and
selected_right in PainterInfo. These tell whether the selection
continues at the left/right of the inset.
This information allows to
1/ paint equation number in the right color: either current text color
or selection text color.
2/ before that, paint a small background rectangle of the correct color.
This allows to avoid painting a large rectangle of an arbitrary color
that was the cause of the bug.
Fixes bug #12319.
When the cursor cannot move on cursor up/down, at least the selection
should be cleared (when not selecting).
To detect this, the method Cursor::upDownInText has been modified to
return true when cursor is at top/bottom of inset, but there is some
room above/below.
Moreover, introduce the functions LFUN_FINISHED_UP/DOWN, which is
dispatched at upper cursor level as long as no local movement is
possible. This allows to handle differently the original char moving
action and its consequences.
Fixes part of bug #12310.
Example: when a selection is set, a `Left' cursor movement would not
reset selection when the cursor was at the beginning of buffer.
To fix this, it is necessary, when cursor is in top-level text, to
avoid the mechnanism (undispatched cursor) that sends the action to the
upper level (necessary when the cursor leaves an inset).
The change is mechanical and is done for : char-backward,
char-forward, char-left, char-right, word-left, word-right, word-left,
word-right. It might be possible to factor this code a bit, but there
is no evident solution.
char-up/down are *not* handled at this point.
Fixes part of bug #12310.
Horizontally, the old code would count an extra pixel on the right.
The vertical test is not changed, and should be eventually audited.
Fixes bug #10468.
I wanted to remove the test Qt >= 5.15, but now I see that it is
not possible because of QProcess::splitCommand.
Neverthless, the best would be to change parsecmd.
QWidget::focusNextPrevChild() passes over to the parent (which is the
work area here) if the current window is not a dialog (isWindow()) or
a sub-window (window flag Qt::SubWindow).
We set the latter here to prevent this unwanted behavior.
Let's see if there are side-effects.
A series of commits, culminating at 812ff7de, pushed a few days later,
fixes the bug at its root. This one is not needed anymore to fix
This reverts commit 001f5a4786
When the buffer stuff has been updated, the Buffer::needUpdate()
should be reset to false. This was forgotten in f3a0e8ff.
Fixes performance issues with MergedManuals, for example. UpdateBuffer
would be run again and again when selecting text.
Introduce a GUI-less LyXRC member bookmarks_visibility. This is
experimental and will not be documented for 2.4.0. Having the code
present will allow to (1) improve it gradually and (2) fix the many
bookmarks bugs that it exposes.
The corresponding tag is \experimental:bookmarks_visibility, which is
intentionally weird.
Three possible values:
* none: no bookmark display
* margin: display the bookmark in margin
* inline: display the bookmark at cursor position.
The default margin has been made wider so that there is room for the
bookmark. This was necessary anyway. The margin bookmark is now
displayed correctly in full screen with limited text width.
Margin display still needs some improvements when several bookmarks
are on the same row.
Mostly fixes bug #2496.
1/ fix horizontal position of the insets
This is adapted from parts of racoon's patch for bug #12131.
2/ fix height of the indicators when at the top or bottom of document,
by using the row's contents_dim() to measure is height.
3/ fix partial blinking of horizontl scrolling marks when editing table.
Fixes bug #12171.
It was an error using an absolute size instead of one relative to the
size of the used font. It was requiring using the physical dpi of the
screen and caused #12222. Now everything is computed with respect to
the metrics of the font and should be automatically correct.
Fixes#12222.
This is for choosing a local document class/layout file. The tooltip
uses the 'class' language already, and "Local Layout" conflicts with
the way that term is used elsewhere in the dialog.
Add new funciton Debug::badValue, that returns the first bad value in a debug
setting string.
Use it to parse the -dbg comand line option and to control the
execution of the debug-level-set lfun.
Use range-based loops in a few places.
Patch from P. De Visschere
Citing:
I also must exclude the QMacPasteboardMimeGraphics class in
GuiApplication.cpp since QMacPasteboard is not available anymore with qt6.
and add an #include <QStandardPaths> in support/Package.cpp (I suppose
this will pose no problem for qt5 but have not checked it, it's only
needed with USE_MACOSX_PACKAGING)
Now it is possible to set this font directly instead of relying on
metrics() side effects. Do that to avoid crashes due to bad
interactions.
This implements the new scheme that was mentionned in 5a58ca65.
Fixes bug #12204.
This code was previously in InsetCollapsible for no good reason.
Move it to a new function InsetText::setOuterFont, which can now be
called for other purposes.
Part of investigation of bug #12204.
The font is already set to the buffer font when called from
TextMetrics::redoParagraph and RowPainter::paintInset, because
inheritFont() is false.
Part of investigation of bug #12204.
This commit allows compiling LyX with Qt6 when using autotools.
For a successful compilation the following 2 conditions must be met.
1) The Qt6 qmake has to come first in PATH, so that the command
"qmake -v | grep -o 'Qt version .'" returns "Qt version 6".
2) The --enable-qt6 switch has to be passed to the configure command.
If --enable-qt6 is used but Qt6 is not found, Qt5 is tried as a fallback.
If also Qt5 is not found, configuring for Qt4 is attempted.
If --enable-qt6 is not used, then things go as usual. This means that Qt5
is tried first and then Qt4, unless --disable-qt5 is used, in which case
Qt4 is directly attempted. This means that existing scripts should
continue working unmodified.
LyX should compile with Qt6 on windows and linux, and possibly also on
mac, but I could not test that. However, it is not guaranteed that it
works as it should. In particular I am not sure that I got right the
conversion from QRegExp to QRegularExpression. For sure, the syntax
highlighting seems to not work right. Someone in the know should take
a look at that. I am able to load documents and compile them but some
thourough testing is needed. However, when compiling for Qt5 or Qt4,
I tried to make sure that the functionality is preserved.
It turns out that the commit from gadmm's lyx-unstable has been
cherry-picked at the wrong place! However I believe that both changes
are necessary.
With this second patch, I do see that some screen jumping is avoided.
Fixes bug #7457.
