This means that, when a string contains high-plane Unicode characters,
the length of a docstring and the corresponding QString will be
different: Qt will encode these characters using several 16bit
characters.
We have additionally to take into account QTBUG-25536, which implies
that sometimes qstring_to_ucs4(toqstr(s)) !=s. It is not clear whether
this bug can be a problem in other places.
Fixes bug #10443.
1. We must always output all (diverging) options, including
default options; if not, default options might get overwritten.
2. Do not output options in \setotherlanguage, since we might have
multiple "other languages" varieties from the same language (such
as naustrian, nswissgerman). And the options are output for the
language switches anyway.
Hence, LaTeXFeatures::getPolyglossiaLanguages() does not have to record
varieties. This was not done correctly anyway, since the map allowed
for one entry per language only.
Math macros can be displayed on screen by providing a different
representation than the one used for latex output. This representation
is actually used by lyx even while it is being updated. This leads to
printing useless error messages on the terminal. For example, a macro
parameter has to be entered as \#1 and, if the macro is already used in
a math inset, lyx prints on terminal the error message "Math parse error:
missing token after \\" as soon as one hits the \ key, followed by
"MathMacroArgument::MathMacroArgument: wrong Argument id: -48" as soon as
one hits the # key. So, this is not a useful information and simply
clutters the terminal output. On the other hand, the input is sanitized
even if one stops input after hitting either \ or #, so that no further
messages are issued. Hence, those error messages are simply pointless.
1/ simplify logic that triggers margin selection painting
2/ fix logic for end of paragraph markers. They are now selected when
there is an end row margin selection.
3/ avoid rounding problems due to int/double conversions.
Also use the exact amount of vertical space TeX adds after a
math display (instead of 1ex) for vertically shifting the box.
We have to use \belowdisplayshortskip here, instead of
\belowdisplayskip, because the math formula is typeset by alone
in a box, and thus there is no following line.
This fixes two particular problems
* with Qt5, it seems that QFontMetrics::width does not return the
correct value for some Arabic text; this patch uses QTextLayout
instead to compute a string width
* Likewise, the undocumented layout flags TextForceRightToLeft and
TextForceLeftToRight do not work with Arabic text; this patch uses
unicode override characters instead.
It might be that the two issues are related. In any case, they do not
happen with latin text where right-to-left direction is enforced. And
they do not happen with Qt4.
Additionally, remove some dead code in GuiFontMetrics::pos2x().
Fixes bug #10436.
LyX assumes that everything in \lyxdeleted is struck out by ulem
and increases the corresponding counter. However, deleted display
math material is struck out using tikz. As we also take into
account the deletion of underlined display math (in order to
properly position such material vertically), we have to take
care that the count is correct.
No newline is written after \begin{document}, such that
the afterParbreak method would return false. This misleads
the code that outputs a display math in an ulem command
to emit a newline command instead of \noindent, causing
latex errors. This occurs only if the math is at the very
start of a document, without anything before it.
- fileformat change
- I could not update the tex2lyx test files because of bug #10440
- maybe the lyx2lyx routine could be improved but since a document can also begin with another layout than "Standard" I could not use the lyx2lyx function put_cmd_in_ert
It should be now possible underlining or striking out any kind
of math inset containing any math construct indigestible to ulem.
While this was already possible for inline math insets, they could
have break if an aligned environment was used, for example.
This is now possible also for diplay math. Even if this can be
nonsensical and not visually perfect, at least no latex errors
should be generated if one tries to.
This should avoid performance problems related to the window update machinery.
Moreover this fixes a crash introduced by 82808fea when closing a file.
Note that GuiWorkArea::Private already had a read_only_ member, but it
was unused.
Also rename LyXVC::vcname() to LyXVC::vcstatus() since it now contains
directly the UI string to be shown.
Font changes are brought inside the \lyxdeleted macro, just before
outputting the latex code for the math inset. The inset writes a
signature before itself and this is checked by \lyxsout for recognizing
a display math. So, the font changes confuse \lyxsout, which also
swallows the first macro at the very start of \lyxdeleted. The result
is that the font changing command is not seen by latex and \sout is also
used to further strike out the formula already striked out by tikz.
This commit makes sure that the expected signature actually appears
just after the opening brace of \lyxdeleted. It also accounts for a
paragraph break occurring just before the math inset, in order to not
introduce too much vertical space, which is noticeable when using
larger font sizes.
LaTeX refuses to break a line when it is empty. But we have to start
a new line here, otherwise the whole displayed equation would be
typeset as it were inline with previous content. The solution is to
put a zero-length space just before the line break. Moreover, this
is the right thing to do, as it simulates the extra space that is
normally added in this circumstance.
Showing deleted display math by enabling "Show Changes in Output" was
only possible with dvi (through dvipost). Although LyX strikes out
such formulas on screen, it was impossible obtaining an output
directly using pdflatex (or other engines producing pdf) because
ulem cannot cope with display math material and gives errors.
The solution is to strike out by ourselves such deleted formulas.
I took into account several options. One of them would produce
an output similar to dvipost (which strikes out each element), but
would have required much more changes in the output routines.
Eventually, I opted for using tikz, which gives a more clean
output (as it requires to simply adding a preamble and a postamble
to the latex code of any displayed math, instead of a mark up
tailored to each particular math construct). The look of the pdf
output is similar to the way LyX strikes out the equations on screen.
Now that there is a signal to inform the controller when the buffer view has
changed, it is no longer necessary to store a perishable pointer to a buffer
view in the dialog view. (Indeed, it was only really useful for checking whether
the new buffer view pointer was different from the old one.)
TODO: other dialogs should be audited for similar hazards.
This enables error reporting for the preamble, provided the preamble is written
using the new InPreamble layouts.
In the future, I find it preferable to deprecate the usual preamble in favour of
InPreamble layouts rather than implementing error reporting for the usual
preamble. This requires some improvements to code editing in the buffer view
first (line breaking behaviour, syntax highlighting).
texstring is a pair of a docstring and a corresponding TexRow. The row count in
the TexRow has to match the number of lines in the docstring.
otexstringstream is an output string stream that can be used to create
texstrings (i.e. it's an odocstringstream that records the TexRow information
and let us extract a texstring from it).
texstrings can be passed around and output to otexstream and otexrowstream,
which produces an accurate TexRow information by concatenating TexRows.
Note that the lyxrc.document_path variable corresponds to what we
call the "Working directory" in the GUI preferences dialog.
Setting document_path to "." makes it so when LyX is started from a
directory, that directory is the default path for many of LyX's
operations, such as the following:
- new file, new from template
- adding a custom BibTeX file
- GUI compare dialog
- local layout button in document settings
- external material file browser
- graphics browser, include browser
The best guess for where the user wants to save or find files is the
directory the user started LyX from. Before, the default was always
the home directory. If desired, the old behavior can be restored by
changing the default path in Preferences > "Working directory".
This commit takes advantage of 9b64d7bd, which allows the use of a
relative path for path preferences.
The limit of 10% is used in both getStatus() and dispatch() to set a
minimum zoom level. Having it centralized makes the code more
readable and makes changing the minimum less error-prone.
* New virtual functions leftMargin() and rightMargin() to get rid of
drawWithMargin()
* Factor and rewrite code for borders.
* Fix several offset calculations.
Known issues:
* Borders of multicols look too good and do not correspond to the pdf
output. (non-regression)
* Bounding box for Hull (Regexp) not pixel-perfect.
* Bounding boxes of Diagram, XYmatrix, are too tight when there are
borders. Also border should be disabled. (non-regression)
A better solution would be to entirely get rid of this borrowed pointer with
unclear lifetime, but this requires to introduce a new signal for when the
buffer view attached to the GuiView has changed.
Until now this was not done for essentially two reasons. The first
one is that local switches are used for short text insertions, so that
they are unlikely crossing environment boundaries. The second one
is that if we have to close a language at the end of an environment
we would be missing the right termination command. As this last
issue can be overcome by simply storing in the stack the current
nest level with a sign denoting the kind of switch, there is no
reason anymore not to track also local languages switches.
Also factor out some commonly used constructs in order to improve
readability.
If the document language is opened outside of any environement, we risk
not closing it if no other language switch occurs. Indeed, the stack is
emptied only at the end of an enviroment. We could of course also empty
it at the end of the document, but we would have an unnecessary language
switch.
Trying to spare a few cycles by avoiding computing metrics during
screen updates and export. See also 8f86ee74, 72cf7c8f, and e36a8903.
Guillaume will tell whether this also avoids crashing his documents ;)
Some macros defined in the lib/symbols file are classified are texmode.
But the MathMacro class was missing a currentMode method for returning
this information.
When using polyglossia, lyx was making a real mess when changing
language inside nested insets. The \begin{language} and
\end{language} commands were not well paired such that they could
easily occur just before and after the start or end of an
environment. Of course this was causing latex errors such that
"\begin{otherlanguage} ended by \end{environment}".
There may still be some cases I did not take into account.
TexRow now returns a range {start, end} when looking up a particular row.
Reverse-search now selects the whole range instead of simply moving the cursor.
Add an exception to the conversion of "missing character" warnings into errors.
The PGF package deliberately uses the dummy font "nullfont" to suppress output.
Therefore, warnings about missing characters in "nullfont" are really only warnings.
Also updated the comment: "Missing character" warnigns are especially widespread
in XeTeX/LuaTeX but can also happen with "classical" 8-bit TeX.
Feel free to port this to branch.
The title is changed to "LaTeX (pdflatex) Preview", etc. depending on the
format. The actual default format is computed.
The menu name "Source Pane" is replaced by "Code Preview Pane" to better reflect
its purpose.
When resolving biblatex's xdata references, consider that xdata fields
can contain a comma-separated list of keys, not just a single key like
crossref.
In addition to the classic crossref, biblatex introduces xdata
references in order to source-out common data of entries. Entries
that have "xdata = {somekey}" just inherit all fields from the
respective @xdata entry, if the field is not already defined in
the entry itself (just like crossref, with the exception that @xdata
entries themselves are _never_ output on their own). @xdata entries can
themselves inherit to other @xdata entries (ad infinitum). So you can,
for instance, setup an xdata entry for a book series with series name
that inherits an xdata entry with information of the publisher
(publisher, address). Any book of that series would just need to refer
to the series xdata and add the number.
BiblioInfo now checks, in addition to crossrefs, for such xdata
references and inherits missing fields.
Nte that biblatex also introduces an "xref" field as an alternative to
crossref. We must not care about that, since the point of xref is that
it does not inherit fields from the target (just cites that one if a
given number of refs to it exist)
Do not assume that the /systemlyxdir path prefix in \origin refers
to the system directory of the running instance, but check through
some heuristics what the real system dir is. In this way, a document
in the system dir of any other LyX installation is correctly spotted
and the \origin tag properly updated. For example, one can use an
installed version of lyx to edit a document in the lib/doc dir of a
git repo and obtain the same result as when running lyx in place.
Revert to the strategy used at 8f86ee74 but not using mathedWordList
because it may be still uninitialized at load time. Instead, use the
globalMacros method for getting the same info.
There was a thinko at 8ec91e80, because globalMacros always returns
null for user defined macros.
