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 24c29908.
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.
When a buffer is in an embedded work area (adv. find&replace), it is
not found by BufferList:::exists(), and therefore the undo group
created in GuiApplication::dispatch and in the handling of
LFUN_COMMAND_SEQUENCE will not be closed.. Crashes can ensue, as
described in Ubuntu bug:
https://bugs.launchpad.net/bugs/1737429
The solution is to introduce BufferList::isInternal and act on it.
Fixes bug #10847.
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.
Fixes bug #10814.
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 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.
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.
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.
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
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.
Along the lines suggested by JMarc, we now collect the list of bibfiles
in use in the updateBuffer routines. This actually does simplify the code
quite a bit. See the discussion there for reasons to go this way.
No intended change of behavior. The ones that use DocIterators and
ParIterators cannot yet be changed, but they could be if we provided
the right sorts of methods, perhaps.
- the column width must be as wide as the column header text
- also center the radiobuttons in the table
- also use alternating colors for the table rows
Basically, everything that does not depend on a BufferView should move
there. Some methods that do not seem to need a BufferView, like
selHandle or IdxFirst or push actually depend on it and could not be
moved.
This allows to simplify a few uses of recordUndo helpers.
- Move some methods to DocIterator: nextMath, prevMath, getPossibleLabel,
getEncoding;
- Move some methods to CursorData: setCursor, setCursorSelectionTo,
(setCursorTo|normal|reset)Anchor, (set|clear)Selection,
sel(|ection)(Begin|End), selectionAsString, info, currentState,
(mark|clear|check)NewWordPosition, fixIfBroken, sanitize, all undo
related methods, reset, isInside, leaveInset, current mode;
- kill some unused methods: macromode, replaceWord, setScreenPos, touch,
markInsert, markErase;
- Move code around to group things, and add a few comments (a lot remains to be done).
This changes lead to some related changes in other classes: removal,
change of parameter.
No intended change.
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.
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.
- If a display math not starting a new paragraph is deleted, the
current \lyxdeleted macro (if any) must be closed and a new one
started, otherwise the display math will be shifted up.
- Use \linewidth instead of \columnwidth because the former will adapt
to the reduced horizontal width in list environments, avoiding shifting
to the right the diplay math.
Spaces are, amazingly, allowed at the end of bibliography keys. So we
introduce a new parameter allowing getVectorFromString not to trim
whitespace, and then use it.
Instantiating a single QSettings and using it for each ui element
can significantly shorten the time required to save the various
states at exit. The speed up can be better appreciated on *nix,
where the settings are saved on disk, rather than on Windows where
they are held in memory (in the registry).
Scanning is rather slow, so this improves performance in specific
situations (multiple inclusion of larger files in master/child or
chapterbib context)

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 covers the most tricky part: the internal naming.
Translations and layouts will follow.
This will all also all be backported to 2.3.x, for the sake of backwards

in updateBuffer().
This is in response to a reported crash. See
https://www.mail-archive.com/lyx-devel@lists.lyx.org/msg202217.html
Commit af381a2f addressed the crash, and is worth doing anyway. But
this also makes sense.
Also adds a flag to tell us whether we need to recalculate the
relevant information. In some cases, there is no need to do so
more than once. (Note that, with the existing code, we *never*
recalculate, which would have given rise to bugs.)
At least with gcc 6.4, if the first parameter passed to
regex_match() is afterward changed, the second one gets
corrupted. This is avoided by using a temporary string.
* Describe the viewport/bb situation more accurate
* Use generic term "coordinates", since bb and viewport are flavor-specific
* Add some tooltips
* Increase the width of the options widget.
The previous redirection of the senseless option "bb" to "viewport" in
PDFLaTeX output has been removed in a recent graphics package update.
This breaks documents, since clipped graphics silently stop displaying.
This change restores the previous output by using "viewport" instaed of
"bb" for non-PS/DVI output, while leaving PS/DVI untouched (where "bb"
and "viewport" behave differently.
Fixes: #7910
Fix several unreleated cases where the `selecting' code path did not
reset cursor font correctly. This leads to a caret that does not have
the correct size, and can cause caret droppings with the new display
scheme.
In some insets such as Arguments, a local language switch has to be
used. However, if the language inside the inset was set to be equal
to the outer language, the code decided not to switch language. But
then got confused and tried to close a switch that was never opened.
This patch forces the switch even if the outer language is the same.
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.
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.
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.
In some cases, it is possible that the BufferPositionMap has
dangling pointers. We thus check whether the Buffer is loaded
before accessing it.
Fixes: #10766
(cherry picked from commit 4f50cbcfe4)
Replace the tricky code in LFUN_SCREEN_FONT_UPDATE and replace it with
proper use of DispatchResult flags.
LFUN_BUFFER_ZOOM* does not need to call LFUN_SCREEN_FONT_UPDATE, since
it already does everything that is required.
This avoids endless resize issues on HiDPI systems (e.g. Retina Mac).
Rename pixel_ratio_ to last_pixel_ratio_ to emphasize that this is a
cached value.
Inline needResize method to make the logic clearer in paintEvent.
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).
This change solves dialog stacking problems on newer Mac OS X in combination with the OS provided file open dialog.
(cherry picked from commit 97dc585138)
Now painting the workarea is done at paint events as should be.
Explicit painting after updating metrics has been replaced by a much
lighter procedure (updatePosCache) to update the insets positions cache.
Expected benefits:
- better performance
- proper use of subpixel aliasing
The LyXRC variable use_qimage is not needed anymore and is therefore removed.
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.
This fixes the display of closed ERTs, Indexes etc. when they contain
special chars, logos or quotation marks.
(Since quotation marks in ERTs are now insets, not chars anymore,
this also fixes a bug/regression of the display of babel shortcuts
such as "= in closed ERTs; hence I consider this fix necessary for 2.3.x)
Remove the trimming operation on LabelString, LabelStringAppendix,
EndLabelString and LabelCounter. This trimming meant that quotes
strings were not preserved, which is wrong.
To preserve layouts, the Layout format has been updated to 64, so that
layout2layout can remove extra spaces on existing strings, which
ensures that behavior is unchanged for old layouts (courtesy of rgheck).
It is now possible to re-add spaces in label strings where it makes
sense.
Fixes bug #10723.
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.
This fixes 3 bugs:
1/ only spaces are considered as part of the prefix
2/ leading tabs are removed unconditionally
3/ off-by-one error in the removal
The new intended behavior is:
1/ find the prefix (sequence of spaces and tabs) before the first
line; remove this prefix from the line
2/ on the next lines, check whether they start with the same prefix,
and if they do, strip this prefix
It was not a good idea to rely on QTextLine::naturalTextWidth() to
compute a string width. The correct method is horizontalAdvance().
Also round the value to the nearest pixel, since this is what
QFontMetrics::width() does.
Fixes bug #10700 (and maybe others).
Dispatching LFUN_BUFFER_ZOOM inside of GuiView::restoreLayout() was
blocked in some cases because the function can be called without a
buffer (and the LFUN is marked as needing a buffer). Instead of
conditioning on a buffer, the call is removed because in testing it
does not appear why it is needed.
This commit removes the status message that is displayed if starting
LyX without opening a buffer:
"Command not allowed without any document open"

This commit amends 4183a9f4.
Due to its peculiarity of not being saved in the document, the
shell escape setting was applied immediately without the need
for hitting the Apply or OK buttons. However, for uniformity
sake, it is better to adhere to the established paragdim of
confirming any changes before applying them.
Allow a LaTeX backend to run external commands after user confirmation.
This is a per document and per machine setting. The authorization has
to be given through the document settings pane, but is not recorded in
the document itself. Moving the document to either another computer or
another directory on the same computer revokes the authorization.
This can also be done by right clicking the red icon that appears in
the status bar when a document is marked as one requiring shell escape.
The patch also checks whether the user has added the -shell-escape
option to a LaTeX converter and nags the user to remove the option
(which would be used for all documents) in favor of the (per document)
support offered by LyX.
- Do not warn when the document properties pane is opened but only
when minted is selected and the pygmentize command was not found.
- Warn before launching latex if minted is selected and the document
actually uses listings insets.
Replace four cases of 'default: ;' in VCBackend.cpp with
default:
break;
Justification: Make consistent with the rest of the LyX source code.
I found no other occurences of 'default: ;' in the source.
Fix some editorial whitespace errors in AspellChecker.cpp.
Changes are non-controversial and I've reviewed them manually.
The whitespace errors were distracting from the big picture while
using the file to work on candidate(s) for a clang-format
configuration.
QSignalBlocker in updateScrollbar is too strong and prevents the scroll bar from
communicating with its scroll area. The only solution to block signals between
specifically between two objects is to disconnect. This makes sense in this
case, by making updateScrollbar responsible for managing the connection in the
first place.
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
Since TeXLive 2016, "fontspec" maps the ligature break command
\textcompwordmark to the ZWNJ character (U+200C).
This character is missing in many fonts (including the default: Latin
Modern) which leads to "Missing character" warnings in the XeTeX/LuaTeX
log file if a document using non-TeX fonts contains a ligature break.
LyX reports missing characters as error since fixing #9610.
In case of "invisible" characters, there is no data loss, in case of the
ZWNJ the functionality is kept: ligatures are prevented also if the ZWNJ
is missing in a font.
Therefore, a missing ZWNJ is now treated similar to missing characters
in "nullfont" (see [63f41711/lyxgit], bug #10394) and does not trigger
an error.
Fixes: #10727
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.
This is a fixup to fc7fb6a564. The fix in there seems perfectly
correct (up to now), but for some reason, I could not refrain from
making InsetInfo not active. "What could possibly go wrong?", I heard
myself think.
Now I know: this causes an assertion error in InsetText::updateBuffer
because DocIterator::forwardPos does not enter the inset anymore.
This is a fixup to the series of commits 522516d9, d0acc3e5, 13c3c148.
Actually the right thing to consider in all situations is isActive(),
which really means `can a cursor be in there?'.
Improve the description of isActive() and editable() in Inset.h.
Set isActive() to false for InsetInfo, since no cursor should ever go there.
Again part of #10667.
Fix the whitespace in e.g. 'QString&' to 'QString &' as this
incorrect, but primarily to simplify a comparison related to
later possibly introducing the use of .clang-format.
When trying to read a textclass, read(Lexer, Readtype) parses and
executes the first token and only then verifies that its effect was to
set format properly. Otherwise it exits.
This is wrong, because if the first tag is "AddToPreamble", then it will
have modified the preamble by the time we notice it was not "Format" and
therefore exit.
The new code starts by requiring a correct "Format" tag.
Fixes bug #10725.
Move the code that forbids character insertion in its own helper function.
Call this function before doing a recordUndo. This avoids to mark the
document dirty in cases where nothing happens.
Part of bug #10721.
Using a regular expression to find /src/ or \src\ in a string is overkill,
and since regexes can throw exceptions, it makes coverity nervous.
The new code is simpler anyway.
We have a mix in this file of boolean stored as such or as strings.
This translates to values written as true/false or 1/0 in .lyx files.
In this case, the value of use_minted could only be true, since the
char * pointer is non null.
Also add some else clauses.
Spotted by coverity.
This is a consequence of e91572a0, although it is not clear why. The
contextMenuEvent code of the workarea should not delegate context
menu when it cannot honor it.
Also fix a small memory leak.
Fixes bug #10616.
The code in InsetLabel::updateReferences code changes reference insets
in potentially several buffers. When recording undo, it is important
to use the right undo stack, otherwise crashes can ensue.
Once it is done, it is neccessary to create undo groups as needed.
This is done using UndoGroupHelper. This demonstrates a shortcoming of
UndoGroup helper: if a buffer is encountered in two seperate
occasions, two undo groups will be created for this buffer. This is
not correct.
Fixes bug #10643.
While 522516d9 was too strong and broke mathed, d0acc3e570 is too
lenient and can accept insets (mathed/CommandInset, InsetInfo) that
have a positive nargs() but are not editable (because they encapsulate
something).
Therefore the best solution for now is to use editable() in text and
isActive() in mathed, until those two things are merged.
Part of #10667.

Fixes#10711.
Pygments versions prior to 2.0 only accept lower case names for lexers.
This commit makes sure to always use lower case names for the language
that is written in the LaTeX file, while retaining the proper casing
for the presentation in the GUI, which is dictated by compatibility
with the listings package. Moreover, if one switches from listings
to minted in a document, the language combo is properly updated even
if the used language had attached a dialect (a concept not shared by
minted), or even when importing a LaTeX document with tex2lyx.
In some (not yet understood) situations, the paragraph metrics cache
is empty in generateSyntheticMouseEvent(). We just avoid a crash in
this case, but there is probably an underlying problem that deserves
being fixed.
Fixes bug #10324.
Both listings and minted allow for many complex options. So, a latex
source can be easily written as
\documentclass{article}
\usepackage{minted}
\usepackage{graphicx}
\usepackage{dingbat}
\begin{document}
\begin{minted}[breaklines=true,
breakautoindent=false,
breaksymbolleft=\raisebox{0.8ex}{
\small\reflectbox{\carriagereturn}},
breaksymbolindentleft=0pt,
breaksymbolsepleft=0pt,
breaksymbolright=\small\carriagereturn,
breaksymbolindentright=0pt,
breaksymbolsepright=0pt]{Python}
def f(x):
return 'Some text' + str(x) + 'some more text' + str(x) + 'even more text that goes on for a while'
\end{minted}
\end{document}
The used text editor can therefore add a mixture of tabs and spaces.
The white space after the options is not a problem and the imported
file compiles just fine, but the validator gets confused and doesn't
validate them. This would entail a difficult editing of the options
only to have them validated. So, better remove the white space.
This commit updates tex2lyx in order to also import minted listings.
For the floating version of a listing, minted uses the listing
environment, a concept that is not shared with the listings package,
towards which our listings inset is geared.
For this reason, a kludge is necessary when importing minted listings
not previously exported by LyX itself.
If the floating listing contains only a caption and a label (other
than the listing itself), everything is fine and the import is (or
aims to be) perfect. But, as in all other floating ebvironments,
one can also stick there other elements, which don't have a place
in the listings inset. So, in order to avoid a data loss, tex2lyx
sticks everything into the caption. In this way, things may be
rearranged in the GUI, if necessary. There is no other way, apart
from a complete redesign of the listings inset, of course. However,
I think that this is an acceptable compromise.
This removes the use of rectText in RenderButton. The fact that this
gave different spacing than buttonText was a problem.
Now buttonText requires to specify
* the offset, so that INSET_TO_TEXT_OFFSET is not used anymore in
src/frontends/, which will be useful later.
* the background and frame color, in replacement for the hover state.
Remove the methods button() and buttonFrame() from GuiPainter.
Remove some unused header files.
Fixes bug #10704.
If
1. the inset is deleted before pasting its contents in the outer text, and
2. the inset contents begins with an inset, and
3. the clone of this inner inset is allocated at the memory location just
made free,
then bad things can happen.
To avoid this, we delete the inset only after its contents has been pasted.
Fixes bug #10667.
This is the same issue that was addressed in the all_sel case at
695b0cc3. The rounding issue only happens at specific zoom and
jusification values.
Fixes part of #8883.
The test added at 359aef92 was incorrect. Actually, Inset::editXY
returns the inset when it is edited and also when it is not, which
can be confusing. So if we are unlucky and the slices positions in the
text area and in the inner inset match, the code below triggers and
many bad things can happen.
Also improve the documentation of Inset::editXY and TextMetrics::editXY.
Fixes#10691.
In the document settings allow to immediately switch from one
package to the other for parameters validation without the need
of first applying the changes.
Several comments in the code point to the fact that hidden buffers are assumed
to be clean.
The other solution was to adapt the closing & saving code to take into account
hidden dirty buffers. Experience shows that it is more useful to unhide the
buffers at the moment of the external modification, in the context of a git
workflow where one has to reload the modified children buffers one-by-one.
Fixes crash at #10603
When the Buffer is notified to be externally modified, check that the
file contents have changed using the checksum.
Document the shortcoming of FileMonitorBlocker.
Fixes#10642.
Starting at 61b2bd5e, boost::bind was progressively replaced with
std::bind. They are not interchangeable though. boost::bind implements
the tracking of boost::signals{,2}::trackable objects. Now that
std::bind has completely replaced boost::bind, tracking never occurred.
This commit replaces boost::signals2::trackable with the new preferred
boost::signals2 methods: scoped_connections or slot::track_foreign. The
support::Trackable class introduced is less safe but easier for transitioning
old code.
Fixes the crash at #8261.
- Remove "chapter" and "section" as this are to be passed as class
options and are otherwise not recognized.
- Let onoff=false for all TRUEFALSE parameters, otherwise only the
form option=true is accepted and option=false does not validate,
generating a lot of confusion.
Minted provides for captions only with floating listings. However,
listings always allows captions, and our machinery is geared accordingly.
So, instead of discriminating the floating and non-floating cases,
always allow for captions with minted, too. When minted does not provide
for a caption, we will provide one.
In the child document case the caption will always be before the listing,
while for the inset case the caption will be before the listing if it
is entered as the first line, after the listing otherwise.
We stored the combo position index, but this changes on engine switch.
This also fixes a crash due to out-of-bound index at engine switch.
Fixes: #10692

editXY() should probably have a documented way to indicate whether the
cursor has entered the inset, although the test used right now is
probably OK. The inset value is useful mainly for context menus or
tasks that need to know which inset the (x, y) coordinates
point to.
Note finally that the documentation of TextMetrics::editXY is
incorrect concerning the return value. It will return a non-null value
if the cursor is on a not editable inset.
Fixes#10691.
This is a follow-up to e194c9ce. There was actually no reason to let
InsetCollapsable and InsetText draw their own background. It is more
correct to remove the existing code and let the generic
Inset::drawBackground take command.
This allows to revert d207e85c.
Fixes bug #10587.
It was possible to insert a caption in a listing not marked as
floating. This didn't cause errors but the caption simply was
disappearing in the output.
When choosing a code language that has dialects in the languages
combo box, the dialects combo gets activated also when minted is
in use. However, minted does not support the concept of dialects
and the combo should not be enabled. This is harmless because the
dialects are simply ignored and the dialects status is restored
after apply, but it may fool the user in thinking that a dialect
can be actually selected. So, always disable it with minted.

Update the listings inset to optionally use the minted package
(instead of the listings one) for typesetting code listings.
Only one of the two packages can be used in a document, but it
is possible to switch packages without issues if the used options
are the same. If a switch is made and the options differ, one needs
to manually adjust them if they were entered in the advanced options
tab, or apply again the gui settings.
Note that minted requires the -shell-escape option for the latex
backend and the installation of additional software (python pygments).
When inserting a column in tabular, the border of the new column
should be copied from the border of the (previously) right-most
column.
Also remove a redundant line. The line
setRightLine(i, true);
was only reached if rightLine(i) was true.
Patch from Daniel Ramöller.
Make sure to properly nest \begin{lang} and \end{lang} tags even
when no language package is selected. In this case, LyX assumes
that babel is being used, so the language names might be wrong
if the user arranged for using polyglossia in the preamble.
Nevertheless, we assure that the produced output is syntactically
correct, so that by adding proper preamble code a correct output
is still possible.
When an inset wants to use the whole available width, it is necessary
to take into account that some of this width may already be taken by
the end-of-paragraph (pilcrow) marker.
Fixes bug #10537.
The RenderButton object now has a inherit_font_ property. It is set
depending on the value of Inset::inheritFont().
This is a better fix than 55533804, which caused bugs #10682 and #10677.
Fixes bug #10258
Do not take the optional arguments from the first paragraph, but from the
paragraphs whose layout have no arguments, consistently with the code in
InsetArgument::updateBuffer (i.e. what was shown on screen).
With these changes, equation numbers are shown properly on screen.
When setting is default, we guess the side using these two rules
* ams(art|book) and siamltex classes are leqno by default. This is
signalled because the classes provide "leqno" (in amsdefs.inc). If
there are other classes that do this in output, the relevant classes
should be updated.
* the language arabic_arabi also sets leqno by default. This is
currently hardcoded for lack of a better idea.
Besides, a few bugs are fixed:
* use mathrm instead of mathbf for numbers metrics
* set spacing between maths and labels in inches
This commit replaces the string math_number_before by a proper math_number enum.
Note that the _before naming was misleading. It was chosen at a time
when we were not sure whether leqno was always left or could be right
in RtL documents.
Note that the token in LyX document is still \math_number_before and
this should be changed.
Fixup for 19cc4a1f.
as discussed our support for the formula numbering side should be complete. There are document classes that uses left numbering as default and with the class option "reqno" this can be changed to right numbering. reqno requires the loading of amsamth.
Consider mathbin, mathrel and mathpunct as word separators. This makes
Ctrl+{Left,Right} more intuitive, quicker, and more different from {Left,Right}.
This takes into account all the feedback from the discussion on the general
list. Further feedback welcome.
Setting the default working directory to '.' is an invasive change
on Mac and Windows, where the current working directory of LyX when
LyX is started from the GUI is not a reasonable choice for the
default directory in e.g. the "save as" file dialog or the "open"
dialog. A similar situation could happen on Linux distributions (I'm
not aware of any, e.g., POSIX standard that defines that the working
directory of a binary started from GUI should be the home
directory). Thus, it is not clear this default is good on any
platform.
If the user wishes to have the behavior of '.', the description in
the "paths" preferences pane provides the information for making the
change.

This reverts commit 892593fbdc.
- Adds a currentZoom variable which holds the current zoom level.
- The zoom stored in preferences is used as default zoom level (default binding:
M+0).
- The currentZoom is saved and restored via QSettings.
- Adds LFUN buffer-zoom for (re)setting zoom.
This is done by two things:
1/ the equation returns LefAlign as display() value
2/ Inset::indent() return a value (in general 0) that should be added
on the left (or right in rtl) of the inset when it is flushed.
The code that uses these values is in TextMetrics::computeRowMetrics.
The current set of options to provide include names of
the find and replace internal buffers, something out of
reach for the user. Furthermore, options are provided
using a multi-line syntax, which cannot be entered
using the mini-buffer AFAIK.
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.
This reverts commit d4ea07705a.
d4ea0770 lead to a compile error with gcc 4.6. The error is likely
due to that version's weak C++11 support.
This commit reverts d4ea0770 in order to preserve compilation with
gcc 4.6 for alpha1.
New special character to mark an optional line break
without inserting a hyphen (ZWSP). See #10585.
Corresponds to the Unicode character U+200B ZERO WIDTH SPACE
This isn't a “space”. It is an invisible character that can be used
to provide line break opportunities.
http://unicode.org/notes/tn27/
While the literal Unicode character can be used in the LyX
file, it is invisible in the GUI.
For visible feedback, the patch adds a new special character "allowbreak".
The small mark is inspired by LibereOffice.
A tooltip is added.
Use Length instead of HSpace for math_indentation and rename it to mathindent.
Get rid of the string version.
Rename (g|s)etMathIndentation() to (g|s)etMathIndent().
Remove the HSpace class altogether.
Some cleanups to parindent support to look like mathindent.
- remove quotes around length
- use "default" for default parindent, instead of an empty string
- Fix the constructor Length(string const &) so that an empty string
corresponds to an empty length (coherent with Length::asString()).
This reverts commit d568846e03.
Unfortunately the used alternative API LSCopyDefaultApplicationURLForContentType
is available with 10.10 and later only and cannot be used therefore. So there
is no alternative to deprecated calls ATM. LyX 2.3 should run on 10.7 at least.
When applying or saving Document Settings, LyX no longer opens or
closes branch insets. The intent of the previous code was to open
branch insets of a branch that is activated, and close branch insets
of a branch that is deactivated.
After some discussion [1], it was decided that the behavior intended
by the previous code was inconsistent with activating/deactivating a
branch in the context-menu of a branch inset, and the previous code
assumed a workflow of the user, rather than letting the user
separate opening/closing branch insets from activating/deactivating
them.
This commit modifies fd6cd728.

1.) The command check_layout exits with "0", even if the module contains errors.
The new module check_layout.cmake tries to compensate.
2.) Added default style to the test layouts when checking single modules.
Seemingly, when removing an argument from argv, and thus inserting
a null pointer to shorten the array, causes an assertion because
the null pointer is not a valid heap pointer (sic!)
Fixes bug #10440
When trying to do implement a LaTeX feature on screen, it is always
good to see how LaTeX does it, just in case it is easy to implement on
our side.
Then we have a correct output at all DPI sizes.
- LyX has new preamble tags. Although that they are not relevant for LaTeX they must be created by tex2lyx nevertheless
- also fix an issue that the formula indentation was always output
- update the tex2lyx tests accordingly
