The old code produced crashes with gcc5 caused by calling the copy
constructor (see https://bugzilla.redhat.com/show_bug.cgi?id=1260976).
This has been filed as gcc bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67557
It is currently being marked as invalid (they claim the code is not valid and
produces undefined behaviour), but I don't think that this is correct.
Fortunately i does not matter for us whether the old code was valid or not,
since the new version is easier to understand and works with all compilers.
Base classes with virtual methods should have a virtual destructor.
See Scott Meyers, Effective C++ item 7: Declare destructors virtual in
polymorphic base classes.
Fix bugs #6501 and #7359.
* Selection highlighting has been broken since a conflict with
reverse-search was repaired (at 00a62b7c), is now fixed.
* The selection highlighting was not accurate, for LaTeX formats (in
full source view), and meaningless, for non LaTeX formats.
* fix regression at cc00b9aa: force_getcontent_ was always true
therefore the code to detect changes in the generated source was
dead. The consequence is that the source view would jump to the
beginning at each updateView() even if no change occurred. Cc00b9aa
was meant to fix#5600, which I cannot reproduce with the new
implementation.
* Various improvements:
* When the position-to-line conversion is unavailable (LyXHTML, LyX
source, etc.) we focus on the first difference instead.
* Get some space around the cursor
* Respect the scrollbars
* Highlight with QTextEdit::ExtraSelections instead of cursor
selection (the latter used to break syntax highlighting of the
TeX code... which was not so much of an issue before because the
wrong part was selected)
Known issues:
* The highlighting is off by one line in very last paragraph of a
document. This appears to be a bug in TexRow.cpp.
* The highlighting is off for any kind of inset. This could be
solved by adapting TexRow so that it accepts CursorSlices as
and argument for the conversion to line number. (this is bug
#4725)
Fix bug #9493. The source panel was very slow with auto-update on. Now
we use a timer that ensures that the source is generated only at
rest. The delay is short or long depending on whether we show the
source of a paragraph or the whole source.
In order to adjust the path of an included file, when deciding
whether the document was moved or not, it is not sufficient
comparing the paths because the document could have been accessed
through a symbolic link.
This was a regression of 0c093a6264. The crash was found by the tex2lyx
test case test-insets.tex: Running lyx -f main -e pdflatex test-insets.lyx.lyx
did crash. This is not a real fix, but will do for now since previews are not
needed in command line mode (I wonder why they are generated at all?) In the
long term, we need theApp() to return a console application in commandline
mode to eliminate the existing sifferences between export from GUI and
commandline.
* Omit commented-out lines
* Properly escape backslash
* Do not allow non-space chars after delaration
* Allow blanks before # comment character
Fixes: #9746
Greek and Times under MikTeX with auto-install may fail due to a half-installed
font package. However, the workaround in LyX stands in the way of
alternative approaches (see bug #6469).
This function inserts a COMBINING GREEK PERISPOMENI character that is
normalized to pre-composed characters for base characters where a
corresponding WITH PERISPOMENI character exists.
This is a partial solution for Ticket #6463.
When a row is too large due to a wide inset, it does not make sense to
break text before if the problem is the same in the next row.
Therefore give up breaking in this case.
Note that this was explicitely taken care of in the old-world
rowBreakPoint code.
Fixes bug #9691.
This is done only inside LFUN_BUFFER_VIEW_CACHE so as to preserve
the benefits of caching in other places.
Without this commit, if a converter or a user (re)moves the preview
file and then calls buffer-view-cache LyX will launch the viewer for
a file that does not exist.
For a discussion and use case, see:
https://www.mail-archive.com/search?l=mid&q=55D393D7.6050403@lyx.org
Both \origin and \textclass tags may be paths and contain spaces.
In this case, enclose them in double quotes such that they can be
correctly read by the lexer.
This solves a few bugs related to the font not being set correctly.
For example, when putting a selection somewhere with
putSelectionAt(), the font was not reset so that before this commit
if the cursor was in an ERT, strange things could happen.
putSelectionAt() is notably used when highlighting the location
corresponding with a LaTeX error (GuiErrorList), when using find,
and when using the spellcheck. I could reproduce the bug using all
three of these.
Bug #9500 is an example of the type of bugs that this commit fixes.
Instead of remembering the last breakable element in the row, search
backward in the row and consider all string elements one by one until
a correct place to break is found.
This fixes the case where the row ends with a string, but there is no
space soon enough in the string to break it here. In this case, we
need to consider the previous row.
We have been here before. The png files are generated, but then by the time we preview the document, they are gone. This is because (a) when the PreviewLoader for a Buffer is deleted, it removes all its previews and (b) we export in a clone, so that Buffer gets deleted before the preview is actually shown. So we need to check whether we are a preview for a clone before we delete anything.
The first change is to concentrate on the last ro elements that contain separators and try to break it a a width that is shorter than both
- its current width (we want to break it, after all)
- the amount of space available.
This simple heuristic seems to give good results.
With this patch, the cursor position before undo can be saved when
creating an undo group. Any such value will supercede parameters
passed to recordUndo. Only the first such cursor set by nested
beginUndoGoup takes effect.
Fixes bug #9663.
If keymaps are activated and there is a secondary keymap but no
primary one, then the pointer to the active keymap was 0x0. This can't
be good.
Fixes bug #9685.
When entering an inset from the keyboard, setCurrentFont()
was not called and thus the cursor retained the font that was set
before. This could create strange behavior that could often go
unnoticed by the user.
It is easy to imagine many other situations similar to #9597 where
the user could trigger this bug.
Fixes bug #9597.
* GuiFontMetrics::pos2x, x2pos: add support for inter-word spacing.
* GuiPainter::text: idem
* Row::Element::countSeparators:
Row::countSeparators: new methods that count spaces in strings.
Row::setSeparatorExtraWidth: new method (code lifted from TextMetrics.cpp).
* TextMetrics::computeRowMetrics: rely on the above methods.
* RowPainter::paintMispelledMarked: pass only a Row::Element object reference
RowPainter::paintStringAndSel: idem; do not rely on values returned by
Painter::text (trailing spaces do not honor wordspacing value).
The goal of this commit is to make painting faster by reducing the
number of strings to paint. To this end, it is necessary to include
spaces in row elements.
Also importantly, this commit should fix existing problems with line
breaking in chinese text.
* TextMetrics::breakRow: do not do anything special for word separators.
* Row::add: when adding a character to a row element, keep the string
width updated. If need be, it is possible to tweak this by updating
every 10 characters, for example.
* GuiFontMetrics::breakAt (new): use QTextLayout to break text either
at word boundary or at an arbitrary width.
* Row::Element::breakAt: use the above method.
* Row::shortenIfNeeded: simplify now that because there is no need for
handling separator elements. This will be taken care of by the
improved breakAt.
Two things remain to be done:
* remove all traces of separator row element
* re-implement text justification.
Actually photos (i.e. .jpg files) where supported previously, but for pdflatex
output an unneeded conversion to png was done. The RasterImage templates
behaves now exactly as InsetGraphics for these files: If the input format is
jpg, use that for pdflatex, else convert to png.
When adding units to the external inset bounding box I overlooked that
InsetGraphics supports only bb, cm, mm and in. Therefore I added too many
units for the external insets. We are not as strict as the graphics inset
and allow all absolute units, but no relative ones.
In breakRow set left and right margin properly for RTL paragraphs.
Remove corresponding code from ComputeRowMetrics.
In row painter, check the use of left and right margin depending on
context. The problem in the original text is that the various
leftMargin() methods actually represent right margin for RTL
paragraphs. This should be fixed eventually.
This made text in smallcaps+emph display as upright instead of plain
emph. There is no latex font for smallcaps + emph, but it is not a
reason for displaying it wrong.
There are many things that are not necessary anymore:
* remove methods paintText2, paintFromPos, leftMargin, paintInlineCompletion
* Remove use of Bidi class.
* add a Font and a Change parameter to paintInset.
Also remove a comment that describes what we have just done.
The new version of paintText is quite short. Elements are treated one
by one. They are already in the right ordering.
The other changes are:
* a new paintChange method is added (using code lifted from old version)
* in paintLast, the support for end of paragraph markers is removed
(this is already part of the Row object.
This path configuration variable is used for user defined location.
There are other possible places for the thesauri like mythes installers or bundled with LyX.
This brings the external inset on par with the graphics insets as far as the
clipping option is concerned. The graphicxs package supports both: A bounding
box without units (which means that bp ia assumed), and a bounding box with
units, so we can simply output the values including the units.
Being able to compile document with zipped .eps files was a useful feature of
the graphicxs package 20 years ago, but the LyX support is no longer relevant:
- The flag is ignored if preview is on
- If pdflatex is used then uncompressing happens during the compilation anyway
- If set, the flag prevents LyX from issuing proper error messages if
something with the image is wrong
- For hard disk capacities from 20 years ago not uncompressing is a useful
feature, but for current hard disk capacities it does not matter
- The external inset does not have it, and if we want to merge both insets
one day we would need to implement it there, which is even more difficult
than in InsetGraphics
The functions reverseDirectionNeeded() and reverseDirectionNeeded() do
not rely on the Bidi class. The first one is changed into a Cursor
method, and the second one is replaced with explicit code.
Since commit 7ac70092, lyx::dispatch returns a DispatchResult const &,
which is ignored in the cases below. Nevertheless, the windows
compiler complains that it does not know this type. Gcc and clang can
deal with it without problem.
The bug workaround added an extra repaint, which can be very bad when
editing large tables.
It turns out that the bug this is trying to fix is due to the handling
of LFUN_LINE_END in InsetMathGrid. Adding the same code as in
InsetMathNest fixes the problem.
The workaround can therefore be removed.
Now the minibuffer toolbar is "auto" by default. It is opened by
command-execute (M-x) and closed when the command is executed without error.
* make lyx::dispatch return a DispatchResult struct
* there is a new MINIBUFFER type of toolbar, that can be used for this use.
* remove special handling of M-x in minnibuffer; Escape can be used instead. Fix focus in this case.
* when minibuffer toolbar is "auto", make the toolbar close itself after
- a command has been executed without error
- an empty command has been executed
- the Escape key has been used
[this is actually commit fdcff02a, which was later reverted at dd61d8cf]
There is a mismatch between the way text is tokenized in Row objects
and the way it is shown on screen. When metrics are computed,
continuous spell checking has not been done yet. Yet, the row painter
explicitly breaks words at spell status boundaries. This creates
problem with a text like "PMP," (see bug #9649), where there is a
negative kerning before the comma.
This is solved by not taking in account spell status when drawing
text, and drawing spell underlines separately.
* replace Paragraph::isSameSpellRange with new method getSpellRange.
* merge RowPainter::paintChars into RowPainter::paintFromPos
* move the actual text painting code into the new paintTextAndSel.
* merge some code from paintFromPos to paintMisspelledMark
* in paintMisspelledMark, scan the string which needs to be annotated
and add dashed line below text marked as misspelled.
Fixes bug #9649.
This avoids warnings with windows compiler. It is a pity that even
clang does not give those. Maybe I missed them with the large amount
of boost warnings that it spits.
There is a second solution in the code which uses some undocumented Qt
stuff, but it does not work in some cases. The best is to rely on the
documented way.
There is no need for real-valued line width in painters. Actually, this even leads to uneven dashes for continuous spell checker.
The new code is supposed to be equivalent to the old one, just more readable. From this, we can try to see whether some lines need to be made thicker on HiDPI screens.
Length::inBP() returned the wrong values for most units. I guess that this was
caused by the default case in the switch statement: It did probably exist
before the other units were added.
inBP() is now correct for all units except the font dependent ones em, ex and
mu and the percent units: For these only approximate values are returned,
since not all needed information is available.
LaTeXFeatures defines \textcommabelow and \textcommaabove based on a
generic \LyXTextAccent and declares TextCompositeCommands for the Baltic
letters in the T1 font encoding, using \textcommaabove for the small letter g
and \textcommabelow else.
This allows overwriting of the composite definition for other font encodings.
Especially, it does not interfere with the polish/baltic font encoding L7x
(supported by LatinModern and TeXGyre fonts) that provides pre-composed
glyphs.
Greek characters with perispomeni (tilde) accent were not properly shown
in the output document, because the "textgreek" feature re-defined \~ in
a way incompatible with lgrenc.def since version 0.8 (2013-05-13)
(package greek-fontenc).
The compatibility-definition is required for older versions of the font setup
(before the move of "lgrenc.def" from "babel" to "greek-fontenc").
It is now done with "ProvideTextCommand" to not overwrite the more complete
implementation in lgrenc.def.
With the compatibility definition, combined diacritics with tilde
must be input with the tilde first (e.g. \~>, not \>~).
"unicodesymbols" is changed accordingly.
Also, some LICRs for combining Greek diacritical characters were added to
Unicodesymbols.
When the cursor had idx > 0 (since math-display does merging anyways),
reset cursor to the start of the inset. This looks less strange than
setting it at the end.
Now at least the basic case of a displayed equation with cursor
somewhere at top-level is handled correctly.
The math-display lfun operates at top level in the math inset.
Therefore, when the cursor is in an inner inset, it will after the
lfun be moved at top level. Unfortunately, there is no way that I know
f to detect this in Inset::doDispatch.
Even if we could, as things stand, it is difficult to keep the cursor in the
inner inset, especially if the inner inset moves : this happens for
example when moving from eqnarray to inline maths.
Therefore this fix is the best I can think of now.
Fixes part of bug #9664.
Both marvosym and bbding define the "Cross" macro.
To prevent a compilation error due to conflicting definitions,
we undefine the "Cross" macro if both packages are required.
It turns out that it is always better using the copy of the MacroData
for updating the macro_ pointer to avoid problems related to the cursor
position.
This effectively makes the horizontal size policy "minimum", which
makes it clear that there is no advantage for this widget of
increasing the horizontal size past the minimum, allowing other
GUI elements to use the horizontal space if useful.
This change for caseCB is consistent with wordsCB and searchbackCB.
This can happen when a macro is copied and then the document where
it is defined is closed. In this case, the macro survives in the
cut stack but the the buffer pointer is dangling.
Now the minibuffer toolbar is "auto" by default. It is opened by
command-execute (M-x) and closed when the command is executed without error.
* make lyx::dispatch return a DispatchResult struct
* there is a new MINIBUFFER type of toolbar, that can be used for this use.
* remove special handling of M-x in minnibuffer; Escape can be used instead. Fix focus in this case.
* when minibuffer toolbar is "auto", make the toolbar close itself after
- a command has been executed without error
- an empty command has been executed
- the Escape key has been used
The 'using namespace std' at the top of the file makes it quite difficult to
understand which abs is used: double std::abs<double>(double) or
int ::abs(int)? Now it is explicit, and the code does not change in subtle
ways if somebody removes the using statement.
The horizontal size policy is now set to "MinimumExpanding", which
means that sizeHint() is enforced as a minimum, but that the widget
can make use of extra available space.
Before, the size policy was ignored, and often resulted in a
scrunched pane that had to have its size manually increased.
The symptom of the bug is that the preference could be incorrectly
displayed (based on the value of the statusbar preference).
This seems to have been a copy/paste mistake introduced in 214f7ed2.
The MacroData pointer is updated by MathData::metrics() which is not
called when selecting a math inset with instant preview for math on.
Thus, we have to update it in the copy constructor otherwise a crash
is almost assured when hitting Ctrl+C.
If latex fails to generate any output, the forked process was not removed.
Now, if a snippet was changed a new one was started but, if also the zoom was
changed, things went awry because the 2 concurrent processes were asked to
process again the same snippet. Previously this would have simply caused a
waste of resources because the changed snippet would have not been regenerated.
Also reset the guard due to the early exit.
If the zoom factor is changed right while the previews are being
regenerated, the refreshPreviews() method is a no-op. So, reschedule
the refresh until everything is ready.
Relying on the fact that the timer is not active anymore does not
guarantee that the previews at the correct zoom are ready because
the regeneration process may take several seconds and during this
time the zoom factor may be changed again. So, we need an additional
guard for assuring that everything has settled down.
We only look once for the definition of the same macro, but we have
to always check its arguments when the same macro appears more than
once in a math inset. So, move earlier this check.
The strategy adopted in bc47054b had some drawbacks related to the way
instant preview snippets are generated. See the subthread starting at
http://www.mail-archive.com/lyx-devel@lists.lyx.org/msg187916.html
for details.
The strategy adopted in this commit is that of adding macro definitions
only for the macros actually used in a preview snippet, independently
of whether some macro was already used in a previous snippet. In this way
the snippets don't need to be changed according to whether they are
compiled as a whole or separately from each other. This fact was causing
the regeneration of a preview snippet whenever the cursor entered the
corresponding inset, even if the generated image would have not changed.
The problem of defining or redefining a macro is taken care by the
python scripts.
Unfortunately I overlooked in 44f73b0650 that the first three whitespace
changes in box-color-size-space-align.lyx.lyx were actually correct, so they
should not have been reverted. In detail:
1), 2): The space after \raggedleft must not be part of the ERT inset, but it
is ouput by check_space() as part of the standard text which follows.
3): The space in front of www is caused by the fact that there is a
newline between the opening brace of the parbox and the \centering
command, so this space is not the one after \centering (which is
correctly swallowed). This additional space is in fact not needed,
and the contents would look better in LyX without it, but since it is
not caused by special code I'll put it back in the refernce for now.
We can still improve this in the future if anybody has a good idea.
The remaining whitespace issues are all fixed by a simple change in
parse_text(): Instead of always eating whitespace after detecting \centering
et al, and always output a space as part of the ERT if these commands need an
ERT, let the standard space handling mechanism kick in: skip whitespace if
no ERT is used (in this case LyX will always output the needed space), and
do not touch whitespace if an ERT is used.
The FIXME is not needed, this is how StyleChanger and FracChanger work:
In the constructor, they change the state of the FontInfo, and in the
destructor the state is set back. Therefore, all code that needs the changed
state, needs to be executed while the objects do still exist.
Until now the regeneration process was starting as soon as the zoom scale
factor was changed. This was causing some glitches, especially if the zoom
was changed by the mouse wheel, as on each change the process was started
again and again making zoom changes painful and causing races such that
one could end up with the text at some zoom factor and the previews at
another one. After this commit, the regeneration is started only after
the zoom factor has been stable for about 1 second. In this way, one can
use the mouse wheel for changing back and forth the zoom factor at own's
heart desire without any slow down due to the regeneration process running
in the background. For those using previews with numbered math equations,
a nice possibility for getting the equations correctly numbered in sequence
(after removing or adding an equation) is using the shortcuts Alt+ and Alt-
in rapid sequence (less than a second between the keystrokes). Previously,
this would have triggered twice the regeneration, but now only once.
Currently, insets are notified that the cursor entered or leaved them in Cursor::dispatch. This is not the cas efor lfuns which are handled in BufferView.
Adding the proper code allows to fix many bugs where previews are not updated correctly.
This also reverts cf4f79f8, which was the same fix for a particular case.
Fixes bug #6173.
Other than checking that we are at the beginning of a paragraph,
we must also check that this is not the first paragraph before
triggering the code that removes the inset separator. This accounts
for the case that we are dissolving an inset from the inside.
Without this additonal check the old code was fooled into thinking
that the separator should have been removed.
The removed code was introduced at [c668ebf6/lyxgit] to assure that
an inset separator in the last position of a paragraph was getting
removed when hitting backspace with the cursor at the beginning of
the next paragraph. Apparently, it is not needed anymore and can
be removed. This avoids the reported assertion.
As JMarc notes on the ML, the referenced commit modifies a full
buffer just in the middle of a dispatch action.
Further, this commit lead to an assertion [1], although it is not
clear to me whether the root cause of the assertion is the commit
that is being reverted here, or one of the issues we have with
previews and macros.
This reverts commit 73460423ad.

Actually, the change is done only if the cursor language was the
document language already.
This fixes an trivial but annoying problem: create a new file (in
English), change language to your favourite language, then start to
write. Before this fix, the words come out in English, which does not
make sense.
Fixes bug #9586.
This is for people who cannot grasp the superior conventions of emacs ;)
A new argument "partial" has been added to word-upcase, word-lowcase
and word-capitalize that restores the old emacs-like behavior.
The (x)emacs bindings are updated to use the "partial" argument, and
also to bind correctly M-u and M-l (M-c is unfortunately not
available).
Fixes bug #2826.
* Provide for vector fonts only if needed.
* Make sure microtype doesn't throw a trantum in dvi mode.
* Use correct macro definition in preview insets.
if a specific one (such as en_NZ-v2.idx) is not found.
If someone can replace the rather clumsy code by an elegant regexp
(I failed to find one), this is most welcome!
These should not have been done without discussion.
- Removal of the dcolumn table in 1a8b74f5e1. Even if LyX does not support
dcolumn anymore, it is still a useful test whether tex2lyx imports it
correctly.
- Removal of the first "%% LyX" line. A long time ago it was decided (after
long discussion between at least Jean-Marc, Uwe and me), that this line is
interpreted by tex2lyx, and used to remove some LyX-generated preamble code.
These lines in the current tests exist on purpose (one can see in the diff
how the removal added unwanted stuff). I do not really like the
interpretation of the "%% LyX" line, but if this behaviour is to be changed
then this needs discussion first.
- Changed comment of \date. The comment was put there on purpose, and the
warning which was "fixed" by the change hints at a limitation in LyX, not a
tex2lyx problem (LyX does not know that a comment inset between some title
insets is OK). The roundtrip .tex output was OK with the old version.
- Change of \verbatiminput{foo}. This was supposed to test whether a
verbatim inset is correctly created even if the included file does not
exist.
- Removal of \lyxlines. Although these tests test input of files created by
old LyX versions, they are useful.
- Change of the lemma in test-modules.tex. The old version was put there on
purpose, and the file itself explains why it is translated to ERT.
The recipe for reproducing this crash is to do a search and replace
that changes a string present in a collapsed inset, and then undo.
This is a followup to 17e435c4, which used editable() instead of
isActive(); this commit was amended at c2f785bd, since editable() is
not set properly in mathed.
Truth is, editable() is not the right property to test against, since
it is false for a collapsed inset, which does not prevent a cursor
from pointing inside. Therefore sanitize should not change the cursor
in this case.
Hopefuly, this is the last word on the subject. Alternative would be
to drop this if()-clause completely.
The documents saved to the system directory have now the origin tag
prefix "/systemlyxdir/". This allows both saving them always using
the same virtual path irrespective of the real path and to let the
origin tag work out of the box also on MacOS.
There is a general problem of tex2lyx handling theorems. it is not sufficient to cure only one instance as I did. For more info see bug #9561.
Update the references accordingly.
With the now removed command we said that this is a file created by LyX but this is not the case
- also replace a comment to avoid LaTeX warnings about mixing title and non-title stuff
before LyX 2.1 was released the dcolumn support was dropped and another method was used to align at the decimal point. Nevertheless the old LaTeX table was even wrong in terms of dcolumn
Now a table is used that uses the decimal alignment as it is supported by LyX
The idea is to get a compilable file that does not require programs that are only available on certain platforms.
For example on Windows there is no Gnumeric available (only a very outdated and unsupported version with bugs).
there were 2 issues:
- the body was not output to the Preamble
- the theorem module already defines a theorem. It must not be output to the preamble to avoid a redefinition error of LaTeX
update the test files accordingly
Since lyX 2.0 we support to use the in_preamble tag. This allows to support more commands. For an unknown reason I forgot the jss.layout when I updated the other layouts once.
Fileformat change
A new preference is introduced for allowing the record of the document
directory path in the saved file. Without explicit consent, it is not saved.
If the origin tag contains an invalid/wrong path or garbage, LyX behaves
exactly as before, i.e., included files are simply not found.
Create new helper class UndoGroupHelper, which simplifies a lot the
handling of undo groups in cases like this one. The class tracks open
undo buffers and allows to switch buffers transparently.
Using the class for advanced search and replace is trivial. THe class
may be useful in some other classes.
Fixes ticket #8658
Add a new tag HasGuiSupport to language file. Add it for all l10ns
that we currently ship. The po files that are unused are not currently
tagged as available, but this could be done, since the code later
checks that the translation is actually there.
This new information is used in GuiPrefs when populating the language
combox.
The new scheme implies that adding a new language is now a two-step
process:
* the language code has to be added to po/LINGUAS, as before;
* one of the entries of the lib/language file has to be selected as
reference and be given the "HasGuiSupport true" property.
This leads to better compatibility with e.g. arXiv.
As Jürgen notes, it is also possible to override this automatic
empty pdfborderstyle via the Additional Options.
Patch by Julien Rioux.
The cleanup in 11ca1406 was not correct. It is actually not possible to implement recordUndoInset from the undo API, since the cursor may not be at a different level than the text to be saved.

LaTeX lengths must not use scientific notation, since the + sign has a
different meaning (glue lengths). This is the GUI part of bug 9416,
on top of part 1 [59e4d16ab/lyxgit].
\framebox{} is equal to \fbox{} and \makebox{} is equal to \mbox{}
When I once wrote this code LyX did not support \fbbox and \mbox and therefore had to use a workaround.
- the idea is to color the box inset frame according to the fame color of the box (if there is any). To keep the WYSIWYM principle the frame thickness and box separation are not taken into account. However this should be possible if anybody would like that.
- besides this, use the correct conversion command for the background color
The math parser could not handle multicolumn grids. This is a problem because
there is no true ERT in math (everything is parsed).
Now multicolumn cells are parsed correctly. The display is also somewhat OK,
but apart from that any multicolumn related UI is missing. Since the file
format change is now done the UI can be added at any later point. The most
important part of bug 396 is now fixed: tex2lyx does not create invalid .lyx
files anymore for formulas containing \multicolumn.
I updated the tex2lyx test cases that produce correct output. tex2lyx does
still produce invalid output for the test cases which are not updated because
of the previous format change.
There were now 2 entries named "none" in backgroundcolorCO
- delete the fixmes; the LateX name is used as parameter to save unnecessary conversions for the LateX output; please ask me before adding fixmes
It is now possible opening documents that where manually moved to a
different location after they were saved and still produce an output.
Indeed, (hopefully) all needed included files are now still found.
When the moved document is saved again, all paths are accordingly updated.
Of course, for this to work, a document has to be saved in Format 490,
at least.
As an example, after converting the user guide to the last format, it can
be copied anywhere and opened without the need of adapting the paths of
included files or moving them to a proper place.
There is one glitch I am aware of. When moving a child document (but not
the master) the path to the master is correctly updated but it won't be
recognized as such. This is because LyX checks that the parent actually
includes this document but, of course, being the parent document not
touched, it appears not including this child. Anyway, it will also occur
when saving the child to a different location and the user is warned
on the terminal about this fact when the moved child is loaded.
However, there is no problem when it is the master that has been moved.
We also get a consistent look with amsmath, so require esint or amsmath.
When resolving alternatives, do also take into account whether the package
is available. For this to work, we also need to test for amsmath.sty (which
was surprisingly not yet done).
stupid me, I used a translatable string as box parameter. Therefore the feature only worked correctly with English locale. Now it works for every locale.
Newer boost versions use complicated type traits for boost::next and
boost::prior, which do not work with the RandomAccessList iterators.
The long term solution is to use std::next and std::prev, for now supply
simple replacements for compilers that do not support C++11 yet.
Revert "tex2lyx testfiles: update to latest fileformat"
This reverts commit afdfc3cf43.
The tex2lyx test vrefernces must be produced by tex2lyx, otherwise the tests
would still fail.
This fixes hopefully the compilation of check_trivstring on cygwin and
solaris. Previously I did not use the explicit instantiation, because c_str()
is used by other explicitly instantiated methiods, but for some reason this
does not seem to suffice.
LaTeX lengths must not use scientific notation, since the + sign has a
different meaning (glue lengths). This is the export part of bug 9416, the GUI
part is still not fixed.
The "save-as" part of the bug is fixed by extending the \textclass tag
such that, if a local layout file is used, its path relative to the
document directory is now stored together with the name. If a relative
path cannot be used, an absolute one is used but, in this case, the
document is not usable on a different platform.
The "copy" part is fixed by introducing a new \origin tag, which is
written when the file is saved. This tag stores the absolute path of
the document directory. If the document is manually copied to a
different location, the local layout file is retrivied by using
\origin (which is only updated on save).
This new tag may prove useful also for locating other files when the
document is manually moved to a different directory.
As in the original implementation the files needed for the layout
(for example, a latex class) had to be in the same directory as the
layout file, this directory has also to be added to TEXINPUTS.
We claim that gcc 4.x is needed in INSTALL, so it does not make sense to keep
this old stuff. Instead, I made configure output an error if gcc is too old.
The command "paste pdf" was always disabled because the
condition in the following "if" statement always returns false
if (arg == "pdf" && (type = Clipboard::PdfGraphicsType))
The value of "type" is zero in this case because PdfGraphicsType is
the first enum value (and it is not set explicitly to non-zero).
An alternative patch is to put AnyGraphicsType as the first
element of enum GraphicsType, or to set the first element to a
number greater than 0.
To test the bug that this commit fixes, either copy a PDF and try to
paste with the action "paste pdf", or click on the "Edit" menu and
notice (before this commit) the terminal output "Unrecognized
graphics type: pdf".
The GNU libstdc++ that ships witch gcc 5 can be used with the same ABI as
older versions, or with a new ABI which is conformant to the C++11 standard.
LyX did not build if the latter was used:
https://kojipkgs.fedoraproject.org//work/tasks/1267/9651267/build.log
This is now fixed by detecting the ABI version and disabling the wrong forward
declarations. At the same time, STD_STRING_USES_COW is switched off for the
C++11 ABI version, because the std::basic_string implementation is now C++11
conformant. Since the GNU libstdc++ can also used by other compilers such as
clang, we must not test for the compiler version.
This is still a hack, but a less dangerous one. The old code had a problem
if it was called from different threads, or if for some reason it would get
called recursively.
The document iterator now skips math insets and insets like notes where spell check is disabled.
The continuous spell checking is part of the row painter drawing and the spell check disabled state
has to be passed down recursively while doing the inset painting.
Because of our better mechanism for dealing with errors (72c5385f),
the problem described in the comment is no longer possible.
NO_OUTPUT is treated as an error so there will no longer be a
lingering PDF in this case.
As Enrico said, the user might have installed a package that was
missing (in which case the .tex file would not have changed).
Another reason is that changing some document settings did not
automatically lead to a fresh compile after an error (#9061).
Our old mechanism for detemining whether there was an error was to
check if the dependent file existed in the temporary directory. If
it did not exist, that meant it was removed, presumably because
there was an error during compilation. That mechanism cannot be used
anymore because we keep the files around even after error because of
the "Show Output Anyway" button (09700d5b). This commit implements a
more straightforward way of checking whether there was an error in
the previous preview by simply storing the success of last compile
in a buffer variable.
The problem was due to the use of the wrong symbol for the slash.
The zero-width symbol for the \not operator was being used.
Using TeX fonts for all symbols gives now a better uniform look.
It is not possible using the alternative code even with Qt 5.4.1
because some glyphs are still missing.
Avoid that \newcommand[x] definitions of math macros are pushed multiple
times to the preview loader.
Redefinitions (via \renewcommand[x]) are properly handled.
The preview snippets are cached in a seemingly random order, such
that, when regenerating them on zoom, the math previews would be
numbered accordingly. Hence, we have to go through the insets to
get the correct order. This is a bit slower but unavoidable.
Note that I move the definition of cur up because we need to check if
it changed before the return. I also removed the const because
notifyCursorLeavesOrEnters() requires that.
This commit probably fixes other issues for any inset that defines
notifyCursorLeaves().
This fixes only part of #6173.
The reason we want to do this is for if there is pasting across buffers.
For within buffer, the previews should already be updated. Calling the
buffer-wide updatePreviews() might seem like overkill, but actually it
should be quick because only the previews that need updating are updated
(and this check feels quick to me, although I did not profile).
If we were to loop through the pasted text and update each preview
individually, this might take more time. When updating previews
together, only one .tex file is compiled.
Normally the theBufferList().updatePreviews(); statement would go inside
of PrefDisplay::applyRC. However, that would not work well because
Buffer::updatePreviews() calls loader() which conditions on
(lyxrc.preview == LyXRC::PREVIEW_OFF) but the new RC has not been set at
this point.
When editing a preview inset, or math, when we leave the inset, we
should update the preview. This update now happens for screen-up and
screen-down (commonly bound to Page Up and Page Down).
Note that this is only relevant if preview is turned on in
preferences.
This commit probably fixes other issues for any inset that defines
notifyCursorLeaves().
This fixes only part of #6173.
Sometimes, even compilable documents could not display preview
snippets. Previously the preview was computed only with help
of latex or xelatex.
This also fixes#9371
The FontMetrics dummy class was in the wrong namespace. Linking on linux
did work because the GNU linker is more clever than the MSVC linker for this
particular example and throws out more unused code, so that theFontMetrics was
not referenced at all.
Control + Shift + PgDn now moves a tab to the right.
Control + Shift + PgUp now moves a tab to the left.
These keybindings are consistent with Chromium, Firefox,
Nautilus, and gnome-terminal.
Note that I allow for wrapping. This is consistent with
allowing wrapping for buffer-{next,previous}, but there
might be reasons to disable it in the future.
buffer-next and buffer-previous are now only enabled
if there is more than one tab. Note that it does not
matter whether we are at the first or last tab because
we cycle.
Since the logout process still can be canceled here, we should only
check that all dirty buffers are saved and that the session state is
recorded.
Please test, particularly on Windows and OSX, that logging out with LyX
running (both with and without dirty buffers) proceeds sensibly and that
the LyX session is correctly restored when you re-login.
We currently cannot restore multiple views of the same buffer properly.
On the mac, we even crash.
So do not try it, record each file only once in the last opened list.
Fixes: #9483.
This fixes a situation where LyX did not detect that something went
wrong (that an external comman crashed) and reported that export was
successful. To reproduce, use the following version of LuaTeX (the
bug in LuaTeX causing the crash has since been fixed):
LuaTeX, Version beta-0.79.1 (TeX Live 2014) (rev 4971)
Then open FeynmanDiagrams.lyx and export with PDF (LuaTeX).
In the documentation [1] for QProcess::exitCode() it states:
"This value is not valid unless exitStatus() returns NormalExit."
For more information, see:
https://www.mail-archive.com/lyx-devel@lists.lyx.org/msg185317.html

Building on cd8be655, we still allow viewing a produced PDF even if
there were compilation errors. However, now the user must click the
"Show Output Anyway" button in the LaTeX Errors dialog. The reason
is that before, there was a chance that the user would not realize
there was an error (because the PDF would be shown over the error
dialog). The approach in this commit makes it more clear that there
is an error.
A new LFUN is introduced, LFUN_BUFFER_VIEW_CACHE. It is useful not
just for the implementation of the "Show Output Anyway" button, but
also to show the last compiled version of a document, which can save
time if a document takes a long time to compile (e.g. heavy use of
knitr).
When at the last position in an inset, selecting to the right
should select the entire inset. This only worked if there was
already a selection (i.e. the selection was started not at the
boundary).
The behavior of this bug was changed by commit 73a7bf9d. Before
that commit, if at the last position of an inset you select to
the right, nothing is selected but the selection is set. If you
select once more to the right, because the selection is set the
needsUpdate condition is satisfied so the whole inset is selected.
Note that everything here applies also to "first position of an
inset" and selecting to the left. By "selecting", I am referring
to LFUN_{CHAR,WORD}_{FORWARD,BACKWARD}_SELECT.
In the test case the crash occured in mathml export of the temporary buffer,
because the macro was updated, and because one of the used other macros was
not copied, the macro argument was detached. However, the underlying problem
of the crash was a broken ArgumentProxy::mathMacro_ reference which became
invalid each time the ownng MathMacro was copied. In the bug test case the
copying happened due to resizing a std::vector, but any other copy would have
created the same problem. The crash did not always happen, because sometimes
the old freed memory was not immediately reused, so the invalid reference did
still point to usable data.
The fix is easy: Convert ArgumentProxy::mathMacro_ to a pointer and update it
always after creating a copy of the owner. The pimpl of MathMacro from the
previous commit helps here to distinguish between the data that can be
automatically copied (in MathMacro::Private) and the cleanup that needs to be
done manually (in MathMacro). This way, the manual copy constructor and
assigment operator of MathMacro does not need to be touched if a new member is
added.
* Remove the UndoKind parameter in the general interface
* move recordUndoInset to Cursor
* remove one variant of Undo::recordUndo.
* get rid of Text::recUndo.
The only real user was Text::insertStringAsLine, but this got changed
in commit 2c7152ab.
While not other place did read the value, there is a side effect of
setAutobreakRow that merges exiting paragraphs. However, this is used
in two situations
* some constructors, where the inset is empty;
* InsetTabular::toggleFixedWidth, which actually contains itself some
code to merge paragraphs.
Therefore the member and all associated code can be removed safely.
Rely only on InsetText::allowMultipar() to get this information.
Implement this method for InsetTabular and InsetBox.
Also rely on this method for disabling LFUN_PARAGRAPH_BREAK.
* Disable "New Inset" button
* Do not disable line edits, but use setReadOnly instead (this allows copying contents)
Fixes: #9408
Note that some dialogs still need some care.
The expanded cells of a mathmacro were previously stored in an InsetMathSqrt.
This was only used as a container for the MathData object in the first cell
of the sqrt inset, which contained the actual expanded arguments.
Funny enough, the only place were the inset property of expanded_ was really
used cannot be seen in the diff. It was MathMacro::kerning(), and this usage
was wrong, since InsetMathSqrt::kerning() always returns 0. Threfore, using
the correct type (MathData) for expanded_ does not only make the code more
readable, gets rid of an unneeded dependency, but also fixes a bug: Now the
correct kerning is returned for expanded cells. Also, expanded_ and
definition_ use the same type now, which looks nicely symmetric.
Previously, things like [ name ] where exported for computer algebra systems.
Now, the expanded macros are exported, which may still be wrong, but now the
CAS has at least a chance to understand what was meant.
Currently, only lfun names are accepeted but there are cases in which
the lfun name does not map directly to an icon. Fore example, in the
outliner, the icon named "promote" is used for the lfun outline-out.
As a result, a graphics inset is used in the documentation for describing
the corresponding icon. Now one can also use an icon name. The argument
of "info-isert icon" is firstly lookep up as an lfun. If no corresponding
icon is found, the argument is taken as the name of the icon. If no such
icon exists, the "unknown" icon is used.
The computation of length on screen depend in particular of the computation of the size of an em. Many places of the code used to rely on the width of the M character, which is not really correct:
http://en.wikipedia.org/wiki/Em_%28typography%29
In digital typography, the best value to use is the point size of the font.
* Implement FontMetrics::em(), which returns the value in pixels of the EM unit.
Convert code to use it.
* Introduce Length::inPixel(MetricsBase const &), which takes the textwidth and em information from the MetricsBase object. Convert code to use it.
* Fix several places where Length::inPixel is used without a proper em value.
* add mathed_font_em() helper function. It should eventually be removed like some other functions in MathSupport.
* Add dummy implementation of FontMetrics to tex2lyx for linking purposes.
I am moving the corresponding code directly to InsetInfo.cpp.
Moreover, the size of the image displayed by the info inset is
now dynamically set according to the text size.
This is a bug reported and fixed by Edwin Leuven.
Here is how Edwin described it in his inimitable minimalist style:
first i merge the top-left two cells in a small, say 3x3, table
if i then merge this multicolumn cell with the remaining cell in the first row
my table ends up all bonkers
This is the rersult of a discussion on the list. Now all special characters
have meaningful names, and it is clear that the LyX file syntax is not LaTeX.
Fixes crash introduced in [17e435c4/lyxgit].
editable() is more related to Texted. It is false for closed collapsable insets
Eventually the two methods should be merged.
Imagemagick detects the inut file format based on contents. Therefore it does
not make sense that we prefix the to be converted file name with the extension
(assuming that the file extension matches the imagemagick format name). This
breaks formats where the extension used by LyX does not match the imagemagick
format name.
I thought I would need it to fix bug #9418, but once backwardInset() worked
it turned out that it is not needed. However, since it took me some time to
figure out the correct implementation I do not want to throw the result away.
The concept of rows and cols is no longer unique to mathed.
Each inset decides itself whether it is grid like or not, so we should not
interfere with this in the cursor slice.
If LyX thinks the export was successful but no output file was
produced for preview, then something is wrong (most likely LyX
did not detect an error that occurred during export).
Also clean up some logic.
A PDF is often still produced after a LaTeX error.
If there was an error when exporting a PDF, we now give an error
and the PDF (if it exists), where before we gave the error and
not the PDF. The GUI and command line behaviors are consistent:
in the GUI an error is given and the PDF is viewed; on the
command line, a non-zero exit code is given and a PDF is created.
This also solves what was in my mind an inconsistency: if the user
"updated" a document and there was an error, the resulting
PDF would be shown; but if the user viewed a document and there
was an error, the document would not be shown.
Note that this applies to all output formats, not just PDF.
For discussion, see:
https://www.mail-archive.com/lyx-devel@lists.lyx.org/msg186454.html
When scanning the LaTeX log, previously we only looked ahead 10 lines
after a "!" line and if we did not find a line number we did not count
an error. This lead to the problem that templates/ACM-sigplan.lyx was
showing a successful export and the PDF was shown (it is still
created despite the error). Now that the exit code of the latex
command is checked (as of the previous commit), an error is correctly
given, but by parsing the log better with this commit, a more
informative error is given.
Increasing the look-ahead to 15 lines leads to correct parsing of
the ACM-sigplan log. The excerpt in the log file where there are more
than 10 lines in-between the "!" line and the line number is below:
! Undefined control sequence.

Another example is posted here:
http://tex.stackexchange.com/questions/231655/lyx-cannot-output-to-pdflatex-for-a-specific-file
Systemcall::startscript returns the exit code of the LaTeX command
that is run, but the return value was not being checked by
LaTeX::run. Instead, we relied on parsing log files. However, this
parsing is not perfect.
The return value is now checked and if the exit code of the command
is non-zero, an enum value is added to the return and the user is
notified of the error.
At a higher level, if the LaTeX command returns a non-zero exit code,
in the GUI a message such as
"Error while exporting format: PDF (LuaTeX)" will be given instead of
"Successful preview of format: PDF (LuaTeX)".
When run on the commandline, lyx -e lualatex example.lyx
will give "Error: LaTeX failed" and a non-zero exit code
where before it gave a zero exit code.
A real example of the bug this commit fixes is LyX's (as of this commit)
ACM-sigplan.lyx template.
Before this commit:
$ lyx -e pdf2 ACM-sigplan.lyx
[...snip...]
support/Systemcall.cpp (288): Systemcall: 'pdflatex "ACM-sigplan.tex"'
finished with exit code 1
$ echo $?
0
Starting with this commit:
$ mylyx master -e pdf2 ACM-sigplan.lyx
support/Systemcall.cpp (288): Systemcall: 'pdflatex "ACM-sigplan.tex"'
finished with exit code 1
Error: LaTeX failed
----------------------------------------
LaTeX did not run successfully. The command that was run exited with
error.
$ echo $?
1
This was disabled in 2009 in bea0925f but it is now safe.
From Richard:
"I am pretty sure that all the work that Peter Kümmel did with the
InGuiThread classes dealt with this issue."
This commit solves two issues:
(1) A PDF from a previous run could have been the result of a command
that exited with error (e.g. sometimes pdflatex still produces a PDF if
it exits with error). If the "View" button were clicked a second time
without changing the .lyx file, then the checksum of the .tex file would
not have changed so LyX would show the PDF (which was created from the
first run that exited with error), and this time LyX would not report
the error (because the parsing of the logs only happens when the .tex
file is compiled).
(2) A myfile.tex that results in no output does not yield a myfile.pdf.
Thus, Any myfile.pdf in the temporary directory will not be overwritten.
Before this commit, the following scenario was possible: LyX runs
pdflatex which processes myfile.tex and no error is given so LyX opens
myfile.pdf. However, it could have been the scenario that pdflatex did
not exit with error and did not create myfile.pdf, in which case
whichever myfile.pdf is being shown is not correct. To see this bug in
action, start a new document, type "abc", view the PDF, delete "abc",
view the PDF (this correctly gives an error that empty output was
created), view the PDF again (this does not give an error because the
checksum has not changed). The PDF shown will contain "abc".
Note that the above also applies to DVI files and that the fix is
general.
Using fraction of points is a reasonable way to avoid warnings with fussy compilers.
Moreover, this fixes the output of PHRASE_LATEX2E to use the proper form \LaTeXe.
The file format still uses the questionnable form \\LaTeX2e.
The problem came from the fact that Qt associates Interlingua to locale C.
Now, we do not rely anymore on the Qt locale to set the language. I suspect that the problem will still exist if the system locale is ia_IA.
Fixes bug #9267.
The old scheme was:
* multiple insertions are undone by groups of 20
* multiple deletions are undone in one big block
The new scheme is to stop merging undo elements after 2 seconds of elapsed time.
Moreover, the merging of undo elements stops when the cursor has moved. Potentially, this could allow to remove many of the finishUndo() calls.
Fixes bug #9204.
It is better to introduce a dummy blank dir in TEXINPUTS rather than
appending a blank at the end. Even if I have checked that this is not
a problem with MikTeX, some other engine (maybe texlive, but I cannot
check) could not ignore this space and take it as the name of a dir.
In this case, TEXINPUTS would not end with an empty element and the
standard search path would not be inserted there.
LyX did not display the limits of the big math operators defined by
stmaryrd.sty correctly. The reason for this was a missing check in
InsetMathSymbol::metrics(), where it is hardcoded which symbols use display
style limits and which symbols use inline limits. In an ideal world this
information would be contained explicitly in lib/symbols.
This should go to branch as well.
If a mask is missing, the TempFile class appends it to the filename.
This may be a problem with applications relying on the extension,
so explicitly add a mask.
If a compressed svg icon is present, load it instead of a png one.
Also introduce two more sizes (huge and giant icons) that should be
useful when using hires displays, as svg icons automatically scale
to the desired size without loss of quality.
tex2lyx did not use the InsetLayout for the script insets, so it did not know
that it had to use Plain Layout. However, there is still a possible pitfall:
InsetScript uses a hard coded plain layout for the InsetText constructor, so
if anybody would remove ForcePlain 1 and MultiPar false from the InsetLayout
then LyX would still write script insets with plain layout, but tex2lyx would
output standard layout again.
We have some math macros that exist only because LyX can display them easily,
but which require user preamble code. These commands should not appear in
autocompletion, they are only there to make the formulas of users who actually
need thgese symbols and know what to put into the preamble more beautiful.
This avoids invoking the insert space dialog instead of the math version. Thereafter, spaces are correctly inserted inside macro templates.
This is the last part of the fix to #9432.
Additionally, move the code to write to a stream from Cursor to CursorData (so that debugging undo is easier). We loose x_target, but I am not sure it is important.
This is the second part of bug #9432.
Previously, LyX did replace some words with typeset logos, and there was no
way to prvent this except putting them, in ERT (bug #4752). Now we have
special insets for these words, and standard text is left alone.
Previously, tex2lyx did not remove the \protect which is output by LyX in
front of \nobreakdash- if needed. Now tex2lyx removes it unconditionally (like
it does elsewhere), because LyX will add it if needed.
The old hyphen replacement code did not convert hyphens if the condition
style.pass_thru || runparams.pass_thru
was met. style.pass_thru got set from inset owner (isPassThru()). Therefore
we have to consider this for the new replacement code as well.
Previously, consecutive dashes in .lyx files were combined to endash and emdash
in some cases, and in other cases they were output as is. This made the code
complicated, and resulted in inconsitencies ((bug #3647).
Now, a dash in a .lyx file is always a dash in the output, for all flavours.
The special handling is moved to the input side, so that you still get an
endash if you type two hyphens. If needed, this can be changed or made
customizable without the need to update the file format again. Many thanks
for the fruitful mailing list dicsussion, which contributed significantly to
the final version.
Again thanks to Scott for finding this. The removal of the check for full
unicode in eb121f999 was not wanted. Now listings can be exported to
lualatex and xetex again.
Thanks to Scott for testing. If a macro is unknown (displayed in red), then
macro_ is 0. The LATTEST is now adjusted and works like in MathMacro::write()
where I stole it from.
For exports based on LaTeX, consecutive hyphens are only converted to endash
and emdash if the current font family is not typewriter, and if none of the
parent insets is an IPA inset. Now this is done for XHTML export as well.
The math icons for the symbol image in the math completer were hardcoded to the
command names. This is wrong for some icons for various reasons, e.g. the case
insensitivity of windows file systems. Therefore we have to use the replacement
list which is also used for the toolbar icons. Bug #3538 is not closed because
of this problem, but IMHO it has nothing to do with this bug, it is a more
general one.
There are several places in the code where a row is painted with drawing disabled in the painter. The goal is only to recompute inset positions.
Such a case happens in BufferView::checkCursorScrollOffset, as part of the horizontal scrolling patch. Note that this particular piece of code should eventually be removed, since it is a performance problem.
It makes sense to consider that only a real painting of a row should change its status. However, I would not be surprised if this change would break other things.
Fixes: #9388

The textcyr test did not work anymore, since the output of
"CYRILLIC SMALL LETTER VE" changed from \textcyr{\char226} to \textcyr{\cyrv}.
The the old version is now converted to ERT. In theory it could also be
converted to "CYRILLIC SMALL LETTER VE", but this would mean to maintain an
extra list, which is not worth the effort.
Rename recordUndoFullDocument to recordUndoFullBuffer.
Separate the notion of recording changes to paragraphs and recording changes in buffer parameters.
Audit every user of recordUndoFullDocument and replace it with either recordUndoBufferParams or recordUndoFullBuffer. Add comments to identify remaining work.
After the str-metrics merge, the kludge for displaying symbols whose
code point corresponds to a soft-hyphen was not working anymore.
The solution is replicating the offending glyphs with index 0x00ad
at a different index. They were replicated at 0x00ac, whose glyph
was missing in all affected fonts.
However, this would not work by alone because, if a system font with
same family name exists, it would be picked up instead of the right one
(at least on non-Windows platforms). For this reason, the style of the
fonts has been changed from "Regular" to "Lyx", so that we can discriminate
the right font. However, this requires using at least Qt 4.8. If an
older Qt is used *and* a system font with same family name is already
available, the affected glyphs will all turn out on screen as the
"logical not" symbol.
I have also set the executable flag on the font files, because on Windows
they are loaded only in this case.
This solves #9229.
The problem was that the conversion to plain text (which is used as an
intermediate step) requires for some insets a valid buffer pointer, but
insets in the cut stack do not have one. Now we use the same temp buffer
business as for copying to the external clipboard.
This commit fixes a thinko in [8bab2338/lyxgit] causing the warning:
QObject::connect: No such slot lyx::frontend::GuiPreferences::slotApplyRC() in ../../../../src/frontends/qt4/GuiPrefs.cpp:3308
QObject::connect: (sender name: 'applyPB')
QObject::connect: (receiver name: 'PrefsUi')
This fixes the -geometry command line option and restores the
"Use icons from system's theme" checkbox in the preferences.
There is still code addressing Qt4 and xlib that has to be
audited. This code cannot be compiled with Qt5 because the
default backend is now xcb and not xlib. I have marked such
code with a "FIXME QT5" comment.
The listings package employs some dirty tricks internally, therefore it does
not work with utf8 encoding, but requires fixed width encodings. This version
of the fix uses ugly hardcoding instead of a layout file format change, so it
could be backported if needed.
This is needed since src/support calls lots of qt code, and some parts of it
(e.g. QFileInfo) require a running event loop. This fixes bug #4917 which is
a symptom of the problem.
The fix is to create a QCoreApplication for tex2lyx, lyxclient and LyX running
without GUI. In the future this could be extended, i.e. to split up the
frontend Application class in a GUI and a console class, and having the
console class use LyXConsoleApp in the same way as Application now uses
GuiApplication. If that is done, one could also think of moving
support/ConsoleApplication to frontend/console/ConsoleApplication.
* \caption does not need to be protected in general
* the contents of \caption arguments need to be protected, though.
All styles related to caoption inset have been audited and updated.
The special casing of captions in longtables has been removed, since there is no special case.
Fixes bug: #9177
This implement horizontal scrolling of rows to allow editing insets
(math, tabular...) that are larger then the screen. The scrolling happens
as the cursor moves, in order to make sure that the cursor is always visible.
This effectively closes an 11 years old bug.
This feature is the result of the work of Hashini Senaratne as part of
Google Summer of Code 2013. The code has been cleaned-up for inclusion
and remaining bugs have been fixed.
Fixes bug: #1083.
