Use the function support:truncateWithEllipsis() to shorten a docstring with
... at the end. Actually we use U+2026 HORIZONTAL ELLIPSIS instead of "..." when
automatically shortening strings. This is to be consistent with Qt's own
truncation and is much nicer on the screen.
This includes the bugs #9575 and #9572 regarding broken text elision in the
outliner.
Known issues (non-regressions):
* TocBackend::updateItem() should be rewritten to update all TOCs. (#8386)
* "..." should be replaced with … everywhere else on the interface (including
translation strings).
* We should prefer to rely on QFontMetrics::elidedText() to truncate strings
with an ellipsis whenever possible, or an equivalent for the buffer view
dependent on the font metrics. See the warning in src/support/lstrings.h.
* TexRow now computes rows from a DocIterator. In practice, the cursor
highlighting is now correct inside insets, it is no longer restricted to the
topmost level. It certainly also makes forward-search more precise.
* Added the option to disable a texrow when not needed, for perf.
* Fixed a bug where the last paragraph was not properly highlighted.
Limitations:
* TexRow still does not handle: math (e.g. multi-cell), sub-captions, inset
arguments.
* New TOC "math-macro". This means that math macros can now be accessed in the
outline pane in their order of appearance or in alphabetical order, and can be
searched using the filter.
* Lists of floats now show subfloats deeper in the navigation menu
* The arbitrary 30 element cut-off after which nothing is shown except "Open
Navigator..." is removed. Menus now have no limit in size, so Qt may display
them scrollable. In exchange, we always show "Open outliner..." at the
beginning. I tested for performance issues with a rather complex document and
it is fine; but this does not exclude corner cases with lots of TOC entries of
a certain kind. If necessary, populating the navigation sub-menu should be
delayed like the main menu.
* Elements that do not contribute to the output (e.g. in a note, a disabled
branch) are now preceded with a symbol indicating this status. (The machinery
was already there; I wonder why it was not implemented already.) I have chosen
U+274E NEGATIVE SQUARED CROSS MARK.
* Fix the contextual menus in the outliner (bug introduced at 94e992c5).
* Toc item now move to the caption when present, but first center on the float,
to prevent the situation where the caption is at the top of the screen and the
contents of the float is off-screen above the caption.
(Internally, the action of the toc items can now be customised)
* Fix the LyXHTML output. Disabled captions no longer appear in the list of
figures.
Remove unwanted clearSelection()s in MathData::updateMacros(). These calls broke
text selection with keyboard and mouse, search-and-replace, restoring selection
after Undo, etc. in a document with math macros since 1.6.0. (Regression at
6aa54673 and 12314897)
I do not know the purpose of these calls, but the selection code has been worked
on since, and I cannot produce undesired behaviour after removing
them.
New method TextMetrics::findRowElement, excerpted from CursorX.
Reimplement getSurroundingPos using Row information. This is easy when
the cursor is inside a row element. At row element edges, different
situations can occur; hopefully all these situations are taken into
account.
Rename the old getSurroundingPos to getSurroundingPosOrig and
transform getSurroundingPos into a wrapper that compares the two
methods. This will be removed when we are confident that the new
function is equivalent to the old one.
It will then be possible to remove also the Bidi class (at last!).
There are still a few warnings of the kind
(style) Variable 'x' is assigned a value that is never used.
since I did not touch code where I was not sure whether there might be a real
bug, and I kept some for symmetry reasons as well.
This fixes cppcheck warnings (style) 'class x' does not have a copy constructor
which is recommended since the class contains a pointer to allocated memory.
These were all flagged by "(style) The scope of the variable 'x' can be reduced."
Narowing the scope improves readability, and if it is in a loop then the
compiler will be clever enough to produce efficient code, we do not need
manual optimization for POD types.
As Günter found out running the tex2lyx tests overwrites the test references
if the build directory is identical to the source directory. Therefore the
tests would always pass, but git diff would show a non-empty diff if the tests
should have failed. Since it is better anyway to build in a separate directory
we simply do not support srcdir = builddir for the tests and abort with an
error.
This generalises the new use of TocBuilder (97e8101) to listings and wraps and
removes some duplicate code.
Make sure that we will never write an empty float type again in the future
(#9760)
We introduce TocBuilder for building TOCs that take into account both float
insets and their captions.
* Floats without caption are shown with their content.
* Floats with a caption are shown with their caption, but clicking the entry now
correctly moves to the float and not to the caption.
* Subsequent captions produce additional entries in the TOC.
* Figures and subfigures are correctly ordered in the outliner.
* New TOC "senseless" for captions appearing alone (a bit like broken references
are still displayed in the menu and outliner).
* Disable LFUN_CAPTION_INSERT if there is already a caption in a listing
Known issues:
* Inconsistent output for includes located inside floats
* We should record the end of the float in addition of the beginning for a more
accurate cursor -> outliner entry conversion
(#9762)
* fixes a bug where this was already the expected behaviour of
math-subscript and math-superscript but failed.
* corrects the behaviour where if there is \newcommand in the
selection, then a corresponding macro template is introduced
instead of a math inset.
* fixes a bug where math-display, math-subscript and math-supscript
would also introduce such a macro template in a way unrelated to
their function. Now it only happens with math-mode without
arguments.
* fixes a bug where a text that does not denote a macro definition,
e.g. "aaa\newcommandaaa", would produce \invalidmacro.
These were all found by cppcheck. Even in constructors that are there "only
because of std containers" the class should be initialized correctly. You can
never know whether such an object does not get used, and then a nice crash
caused by dereferencing a NULL-pointer is better than undefined behaviour.
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.
