As of enchant 2.x, it is required to create a Broker instance instead

Add a `cancel' boolean to macroModeClose() that just removes all trace

As of v. 1.7.7, chktex has four exit values. Only consider the program
failed with EXIT_FAILURE (1). This is backwards compatible to chktex
up to v. 1.7.5 and later patched versions included in TeXLive, where
there was the distinction EXIT_FAILURE (program failed) and EXIT_SUCCESS
(program successfully run, with or without something to report).
Note that ChkTeX v. 1.7.5 and 1.7.6 vanilla (as included in MikTeX) also
returned EXITE_FAILURE if ChkTeX found something to report.
We do not, and never did, support this case.
Fixes: #9989 (after ChkTeX 1.7.7. is released).

This is needed for cases where the temp file has to be manually removed

kept open internally even after close()). See

the old method was removed), we record all used temp file names.

In cursorY, it is dangerous to access par_petrics_[0], since one does

This fixes a regression in e64ea357, where a test has been (badly)

Moreover, improve the test of cursor boundary to avoid the case where
cursor position is already 0.

Qt on macOS does not respect the Qt::WA_OpaquePaintEvent attribute and
clears the widget backing store at each update. Therefore, we use our
own backing store in this case.
This restores a simplified version of the code that was removed at 06253dfe.
(cherry picked from commit 2316435f2f)
The bug is the following: when selecting several paragraphs quickly
enough, some rows do not get selected.This is a consequence of the
removal of row crc, which lead to not taking into account the
selection status of the row in the decision to repaint.
The solution chosen here is to add a Row::change() helper function to
modify row members. This will set the Row changed status whenever the
value of the member changes.
(cherry picked from commit ae60749f89)
When the caret is at end of row, if may happen that it is drawn after
the end of the row. In this case caret blinking will not work
properly. This patch extends the row background on the left and right
by Inset::TEXT_TO_INSET_OFFSET. This is only a hack that will not work
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).
Fixes (mostly, see above) bug #10797.
(cherry picked from commit e64ea3576c)
This computation did not make sense anymore since we began to put the
contents in the Row object. The fact that it worked was a coincidence.
Instead, we set rows as changed() on creation and reset that once they
have been drawn. This will allow in the future for a finer definition
of what to redraw or not.
Also update the PAINTING_ANALYSIS document
(cherry picked from commit 9e2da4a3ea)
It is wrong to compute this at paint time. In general, painting a row
should not require any access to a paragraph object, but we are far
from there now.
(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.
(cherry picked from commit 8d8988de47)
This replaces a showCaret/hideCaret pair and avoids an update.
Also remove an update() call in resizeBufferView: is is not necessary
since we are already in a pintEvent handler.
(cherry picked from commit add342d088)
For some reason the existing code only considered the bottom row that
contained the cursor. There is no need for that, and actually it
caused painting problems in nested insets.
Tweak the logic of repaint_caret_row_ a bit: there is no need for
repainting when there is currently no caret on screen.
(cherry picked from commit 764a153c69)
Replace the tricky code in LFUN_SCREEN_FONT_UPDATE and replace it with

(cherry picked from commit 6532e5104d)
Remove the old schedule_redraw_ mechanism that was only useful because
of our synchronous drawing code. Now that actual painting is
scheduled instead of forced, it becomes pointless.
Rename WorkArea::redraw(bool) to scheduleRedraw(bool), to show that
the drawing is not done right away.
In GuiView::updateInset, call scheduleRedraw(true), so that metrics
are correctly computed (this was the whole point of the exercise).
(cherry picked from commit a31d3dc67d)
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.

Possibility to add an environment before the current one and to append

Now layouts can specify other layouts that should be nested in and
after the current one (if the layout is switched from the current one
and if it follows a paragraph in the current one).
This is particularly useful for things such as the beamer frames, where
particular layouts are practically always nested.

By default, inactive math corners are invisible. In practice they are

After 6642152e, user macros were no longer wrapped in \ensuremath. In 2.2 and
before, InsetMathMacro behaved as follow:
* Textmode global symbols are wrapped in \text when in math.
* Other global symbols, and user macros, are wrapped in \ensuremath when in
text.
* Undefined macros (ERT) are wrapped neither in \text nor in \ensuremath.
This is also consistent with the documentation of MathEnsurer in
mathed/MathStream.h.
This patch defines InsetMathMacro::currentMode() accordingly (respectively
TEXT_MODE, MATH_MODE and UNDECIDED_MODE) and uses it to determine the output.
After this patch, there is a mismatch between screen and pdf output for user
macros in \text. This is not a regression wrt 2.2 and is because linearization
does not satisfy currentMode() currently.
