This fixes a regression in e64ea357, where a test has been (badly)
tightened to avoid that two consecutive rows may be redrawn to get rid
of caret ghosts. The test prohibited empty rows from being redrawn.
Moreover, improve the test of cursor boundary to avoid the case where
cursor position is already 0.
Fixes bug #10952.
(cherry picked from commit 66c677b946)
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)
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.

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)
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).
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.
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.

The current spelling is not strictly wrong, but flagged as unusual or
historical by some authorities. It is also found fault with many
spell checkers. Thus we decided to move to the more standard "-ible"
form once and for all.
See #10678 for discussion
This part only covers the usage in comments and the like. More to follow.
This will all also all be backported to 2.3.x, for the sake of backwards
compatibility (cherry-picking).

If the height of the first row of the document has become smaller (for
example when it contains an image which size has shrunk), that the
anchor offset has to be adapted so that there is not a large blank
space at the top of the document.

Traditionally LyX behaves differently when the directive DEVEL_VERSION
is defined at compile time. This covers
* more detailed description of current position in status bar
* the help files are open in read/write mode
* more detailed debug output in the View Source panel
This patch introduces the new function devel-mode-toggle that allows
to use devel mode in stable releases, and vice versa.
The information is saved in the session file. The default is to
disable devel mode.
Remove all traces of DEVEL_VERSION in autoconf and cmake
This commit does a bulk fix of incorrect annotations (comments) at the
end of namespaces.
The commit was generated by initially running clang-format, and then
from the diff of the result extracting the hunks corresponding to
fixes of namespace comments. The changes being applied and all the
results have been manually reviewed. The source code successfully
builds on macOS.
Further details on the steps below, in case they're of interest to
someone else in the future.
1. Checkout a fresh and up to date version of src/
git pull && git checkout -- src && git status src
2. Ensure there's a suitable .clang-format in place, i.e. with options
to fix the comment at the end of namespaces, including:
FixNamespaceComments: true
SpacesBeforeTrailingComments: 1
and that clang-format is >= 5.0.0, by doing e.g.:
clang-format -dump-config | grep Comments:
clang-format --version
3. Apply clang-format to the source:
clang-format -i $(find src -name "*.cpp" -or -name "*.h")
4. Create and filter out hunks related to fixing the namespace
git diff -U0 src > tmp.patch
grepdiff '^} // namespace' --output-matching=hunk tmp.patch > fix_namespace.patch
5. Filter out hunks corresponding to simple fixes into to a separate patch:
pcregrep -M -e '^diff[^\n]+\nindex[^\n]+\n--- [^\n]+\n\+\+\+ [^\n]+\n' \
-e '^@@ -[0-9]+ \+[0-9]+ @@[^\n]*\n-\}[^\n]*\n\+\}[^\n]*\n' \
fix_namespace.patch > fix_namespace_simple.patch
6. Manually review the simple patch and then apply it, after first
restoring the source.
git checkout -- src
patch -p1 < fix_namespace_simple.path
7. Manually review the (simple) changes and then stage the changes
git diff src
git add src
8. Again apply clang-format and filter out hunks related to any
remaining fixes to the namespace, this time filter with more
context. There will be fewer hunks as all the simple cases have
already been handled:
clang-format -i $(find src -name "*.cpp" -or -name "*.h")
git diff src > tmp.patch
grepdiff '^} // namespace' --output-matching=hunk tmp.patch > fix_namespace2.patch
9. Manually review/edit the resulting patch file to remove hunks for files
which need to be dealt with manually, noting the file names and
line numbers. Then restore files to as before applying clang-format
and apply the patch:
git checkout src
patch -p1 < fix_namespace2.patch
10. Manually fix the files noted in the previous step. Stage files,
review changes and commit.
Length::inPixels(MetricsBase const &) and VSpace::inPixels(BufferView
const &) should be moved respectuvely to MetricsBase and BufferView:
core file are not supposed to use GUI files.
Introduce a distinction between being read-only and having the read-only flag. A
buffer is read-only if either it has been externally modified or if it has the
read-only flag.
Up to now Inset::dimension was either a helper function to access
CoordCache, or... something else. This created problems to properly
use it.
In particular, the definition of InsetText::dimension created problems
for child classes. Removing this definition (actually renaming it to
dimensionHelper) allows to streamline the code.
It turns out that Cursor::getFont() does not return a fully realized
font in some cases. This patch uses real_current_font instead, which
seems better anyway.
I suspect that all uses of getFont() should be removed, but this is
not code that I know well.
Fixes bug #10478.
Trying to spare a few cycles by avoiding computing metrics during
screen updates and export. See also 8f86ee74, 72cf7c8f, and e36a8903.
Guillaume will tell whether this also avoids crashing his documents ;)
TexRow now returns a range {start, end} when looking up a particular row.
Reverse-search now selects the whole range instead of simply moving the cursor.
Revert to the strategy used at 8f86ee74 but not using mathedWordList
because it may be still uninitialized at load time. Instead, use the
globalMacros method for getting the same info.
There was a thinko at 8ec91e80, because globalMacros always returns
null for user defined macros.
The math macros system is quite complex. Macros are updated during
metrics calculation, so a missing update is very likely to cause a
crash. This commit tries to assure that they are updated at export
time, which also happens when the table of contents is updated.
Moreover, in order to circumvent a possible missing update, when
a math macro is detected we try to avoid using the sym_ member
of the MacroData class, as it may contain bogus values.
Prevent setRange() from causing a recursive call to scrollTo(). Reduces three
calls of scrollTo() to one call for all scrolling functions of the scroll bar
(e.g. clicking on the arrow, dragging, or clicking somewhere on the scrollbar).
We need to invalidate the BibTeX cache when undoing or redoing. I do
not like having to do it for every undo or redo. We should only have
to do it if we restored or deleted an InsetBibTeX. But there is no
way, so far as I can see, to do it that way. I tried.
Now that Row has a pit() member, it is possible to use it instead of passing an extra pit_type parameter to a function which already has access to a Row.
The old name would be confusing wrt setSelection(), which does additional checks.
This one is a pure acessor, and the more complete methods are
* setSelection(), which avoids empty selections
* clearSelection(), which resets anchor, and sets word selection and mark more to false.
Most of the code should use these two instead of selection(bool), but this is for later.
