The backslash is the escape character used in our parser. Hence,
when used as a path separator on Windows, it has to be itself
escaped or the path enclosed in either double or single quotes.
Windows users are maybe trained to quote paths containing spaces
but not paths with backslashes. So, we automatically escape the
backslashes when they are not already enclosed in quotes.

This is related to the fix for #9158 and the caching of bibfile
information. On Windows, it is incredibly slow to run kpsewhich,
which we do to check where files actually are, so as to get info
about them (e.g., timestamps). So we have started to cache that
as a map. The map is supposed to be invalidated when various
things happen, but an oversight was causing it to be invalidated
on every cut operation. This is because cutting uses a temporary
Buffer, and the operations on it were affecting the *global* cache
of biblio file info. (It makes sense to have a global cache, since
these files are not document-specific.) Basically, we have to update
the list of bibfiles in that temporary Buffer---but that is one of
the things that invalidated the cache. The solution is only to
invalidate the cache if the list of bibfiles has actually changed
(a sensible idea anyway). The only time that will happen in the
temporary Buffer is when the copied information contains a BibTeX
inset. That should be fairly rare.
The boost signal was sent synchronously, and so made the Qt signal to be posted
in FileMonitor::changed after the boost signal returned, so after the sender was
possibly destroyed.
The solution is to make the boost signal asynchronous using the Qt event loop.

With Qt 5.11 at least, RtL text will be drawn RtL even when the
(undocumented) flag Qt::TextForceLeftToRight is applied to the
QTextLayout object. This creates selection issues for Hebrew text
marked as English.
The solution is to do the same as in breakAt_helper, that is prepend
the string with a direction override unicode character.
Doing this requires to introduce a TEXTLAYOUT_OFFSET constant that has
to be used wisely to account for this extra character.

(cherry picked from commit 2617a4dd50)
When a raster image with an advertised pixel density different
from 72 dpi is included in a latex file, the output image dimensions
are scaled by the ratio 72/pixel_density. Hence, if a clipping
bounding box is specified, it has to be scaled by the same ratio,
otherwise the images will be clipped differently on screen and output.
Here we use the extractbb command (present in any TeX distribution)
to ask about the output dimensions of the image as dictated by the
pixel density and compute the scaling ratio by the knowledge of the
actual dimensions. If, for whatever reason, extractbb is not found,
everything goes as before, because the clipping bounding box will
simply not be corrected.

The goal of this patch is to make "self-insert <string>" act as a
sequence of individual self-insert calls. Once it is done, the
insertion of the commit string in GuiWorkArea can use that, which
fixes the issues described in bug 11183.
1/ in InsetMathNest, SELF_INSERT is rewritten to be a proper loop of
interpretChar, instead of inserting the string as characters. This
solves the issue of interpreting ^ properly.
2/ the text version does not need to be changed (the loop is rewritten
using a range, though).
3/ Then {{{GuiWorkArea::inputMethodEvent}}} is changed to invoke
directly self-insert. This removes the update issues.

Minted does not have a language option but it is possible to enter

This case was not foreseen and thus the option was being passed to
the package as is, causing havoc. With this commit the option is
still available but is used to set a default language for a new
listing in place of the default "tex" language used so far.

The problem with the previous attempt was that, every time through
updateBuffer, we looked up the file location using kpsewhich, which
took too long on Windows. The new solution is to cache that info, and
to look it up only when we need it.
Previously, this info would have been re-read whenever we parsed the
bibfiles. So we re-read it now whenever the bibinfo cache is invalid,
which is less often, but should be good enough. We can add more such
re-reads if need be.

The code in 90cfe4ec3 only handled the cells which metrics are

whether it contains a caret for a given bufferview.

When computing a cell metrics, it is now possible to specify whether it

Use this to make sure that grid insets have large enough cells. It

only cell which is known to be tight is the nucleus of the root inset.
Others should be examined one by one. It might be that the default of
MathData::metrics tight parameter should be `false'.

If a master document is compiled and has errors, and then a child is
compiled without error, the errors from the master compilation were
shown.
The setup of the relevant code is the following:
processingThreadFinished() calls errors(). errors() makes the
assumption that if it is called, there must have been an error
somewhere.
The logic of the setup is the following:
processingThreadFinished() knows whether there was an error on
the most recent preview/export, although it doesn't know whether
the error is from master or child (i.e. does not know whether the
user was compiling the child, or whether master-buffer-view was
called). Inside error(), if there is no error in the child, it is
assumed the error is from master.
For the above logic to work, errors() should only be called if there
was an error.

The bug is the following: when selecting several paragraphs quickly

removal of row crc, which lead to not taking into account the
selection status of the row in the decision to repaint.

modify row members. This will set the Row changed status whenever the
value of the member changes.

When the caret is at end of row, if may happen that it is drawn after

properly. This patch extends the row background on the left and right

if the caret has a ridiculous width like 6.
Additionally, introduce some (disabled) debug code that numbers the
rows on screen by painting order.
Finally, make the code that detects whether the caret was in a given
row more precise (take boundary into account).

(cherry picked from commit 4858bb3bb6)
The goal of this commit is to ensure that a processUpdateFlags call
that requires no redraw will not override a previous one that did
require a redraw.
To this end, the semantics of the flag argument is now different: its
value is now OR'ed with a private update_flags_ variable. This
variable is only reset after the buffer view has actually been
redrawn.
A new Update::ForceRedraw flag has been added. It requires a full
redraw but no metrics computation. It is not used in the main code
(yet), but avoids to compute metrics repeatedly in consecutive
processUpdateFlags calls.
The process is now as follows:
- if flags is just None, return immediately, there is nothing to do.
- the Force flag is honored (full metrics computation) and replaced
with ForceDraw.
- the FitCursor flag is honored and removed from the flags.
- the SinglePar update is added if ForceDraw is not in flags and only
the current par has been modified.
The remaining flags are only then added to the BufferView update
flags, and the update strategy is computed for the next paint event.
Finally the dubious call to updateMacros in updateMetrics has been
removed for performance reasons.

This patch makes sure that, every time a ParagraphMetrics has its
position set, the inset positions for the insets held by this
paragraph are remembered too.
This is complementary to BufferView::updatePosCache, but I do not have
hard evidence that this is required other than to increase robustness.
It may help in some cases when scrolling the document (scrollbar,
cursor up/down, page up/down).
This unbreaks input methods by splitting the part of the code that
does the actual drawing to a separate paintPreeditText() method which
is called from paintEvent().
The proper solution would have been to introduce the preedit string in
the Row object, like is done for completion, but this is too complex
to do at this point.
The only change in behavior is that now the commit string is inserted
in one fell swoop, intead of emulating a number of key events.
Rename cursor to caret to in order to avoid ambiguity. The caret is
now the blinking thing only.
Remove unused header contents, and some not so useful methods.
No intended change of behavior.
The trick is to remember in BufferView what has been done at the
previous draw, so that the row that contained the caret can be
repainted if needed.
To this end, add an argument paint_caret to BufferView, although
painting the caret is not the job of the BufferView (at this point).
BufferView::needRepaint will act as an interface with
TextMetrics::drawParagraph to know whether the painting of a given
row should be forced.
Currently everything is done at the top row level, so that, if the
caret is in a large table, the whole table will have to be repainted.
It is not clear yet that this is necessary.
Historically, because of two-stage drawing, LyX has been painting on a
Pixmap, and this pixmap is copied to screen at paint event time.
Now that we have three-stage drawing, it is possible to delay the
painting to actual paint event and avoid the intermediate Pixmap.
Known bug: the cursor is never erased.
Normally the two stages of drawing are
1/ compute metrics of insets/rows/paragraphs/mathrow...
2/ draw the elements and cache their positions
Now the three stages are
1/ metrics
2/ nodraw: do not draw the elements, but cache their position
3/ draw the elements (and store again their position; it does not
seems to hurt performance).
Revive the NullPainter: this replaces the setDrawingEnabled mechanism
with a painter that does nothing. The advantage is that updatePosCache
(renamed from setPosCache) does not need anymore to be invoked from
the frontend.
updatePosCache (the nodraw stage) is called at the end of
BufferView::updateMetrics.
The work is done now in Paragraph::anonymize().
Move the handling of the lfun to Buffer class.
Document the new feature in release notes.

This is a follow-up to 758de957.
- unify the metrics and drawing of \sqrt and \root using helper
functions mathed_root_metrics and mathed_draw_root.
- compute the vertical spacing above the nucleus of the root following
rule 11 of the TeXbook. In particular, it is different in inline and
display style.
- draw the root glyph without hard-coded pixel values. Make the line
width depend on the zoom.
more work is needed to implement properly rule 11:
- Ideally, we should use sqrt glyphs from the math fonts. Note that
then we would get rule thickness from there.
- The positioning of the root MathData is arbitrary. It should
follow the definition of \root...\of... in The Texbook in
Apprendix B page 360.

Now the helper class contains logic that checks whether buffer are
known before closing them. This avoids potential crashes.
Use it in different places to siplify code. It is not clear at this
point whether it should be used everywhere.
Followup to bug #10847.

It may happen that the buffers are visited in order buffer1,
buffer2, buffer1. In this case, we want to have only one undo group
in buffer1. The solution is to replace buffer_ with a set<Buffer*>.
A use case among others is InsetLabel::updateReferences.

The correct behavior is to go to position 0 going up from first row,
and to end of row when going down on last row.
The targetx value of the cursor is not updated, which makes cursor
movement more natural.
Fixes bug #10701.

The issue here was that the element was only removed from the queue
after the func request was processed, but within that process, other
function could access the queue, so the queue could even be empty
when this function finally wanted to remove the item.

When pasting "\big" without any following delimiter, avoid
processing the same token again and again. For unknown reasons,
the delim docstring turns out to always be not empty: even when
it simply contains a '0' (no delimiter follows), its length is 1.

Several problems:
* The regex failed at names such as 1_text_2_text.tex
(returned "2_text.tex)
* The regex failed at names such as 12_text.tex
(returned "2_text.tex)
* Masters with digits in the name (2018_text.tex) were
tracked as their own children
(cherry picked from commit 398e026250)
At some time it seemed like a good idea in breakRow() to return early
when the row was bound to be empty. It turns out that this creates two
symptoms:
* empty paragraphs will not have an end of paragraph marker
* since row width is not correctly computed in this case, caret ghosts
can appear in master.
This commit removes the oprimization and replace the do {} while()
construct to a straightforward while() {}.

This is currently only relevant fo InsetListings, which falls back to
a fixed-width encoding under specific conditions. It is now possible
to query the inset about that and report the correct encoding in
DocIterator::getEncoding.

(cherry picked from commit f924ef2966)
On platforms where char_type is typedef'd to an integral type
rather than to wchar_t, when using the insertion operator <<
a single char_type is output as the number corresponding to the
code point of the character rather than as the character itself.
In this case, one has to use put().

This gets rid of the hardcoded latin1 encoding for verbatim. Instead,
verbatim now inherits the encoding from the context, which is what is
actually wanted here.

This works around a TextMetrics issue where Row::beg/end_margin_sel
are sometimes not reset correctly when there is no selection on the
row.
In master a fix for this problem has been done at 654cded1. Here we
prefer a much simpler work around that fixes the symptom.

This gives a more consistent indication of what belongs to an environment
(and semantically, such paragraphs are synonymous to nested standard
paragraphs)
Addresses part of #9261.
This is important for info inset, since if updateBuffer needs to be
run in redoParagraph (for the macro code), crashes can happen.
