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.
