This commit replaces the string math_number_before by a proper math_number enum.
Note that the _before naming was misleading. It was chosen at a time
when we were not sure whether leqno was always left or could be right
in RtL documents.
Note that the token in LyX document is still \math_number_before and
this should be changed.
Fixup for 19cc4a1f.
as discussed our support for the formula numbering side should be complete. There are document classes that uses left numbering as default and with the class option "reqno" this can be changed to right numbering. reqno requires the loading of amsamth.
- Adds a currentZoom variable which holds the current zoom level.
- The zoom stored in preferences is used as default zoom level (default binding:
M+0).
- The currentZoom is saved and restored via QSettings.
- Adds LFUN buffer-zoom for (re)setting zoom.
Use Length instead of HSpace for math_indentation and rename it to mathindent.
Get rid of the string version.
Rename (g|s)etMathIndentation() to (g|s)etMathIndent().
Remove the HSpace class altogether.
Some cleanups to parindent support to look like mathindent.
When applying or saving Document Settings, LyX no longer opens or
closes branch insets. The intent of the previous code was to open
branch insets of a branch that is activated, and close branch insets
of a branch that is deactivated.
After some discussion [1], it was decided that the behavior intended
by the previous code was inconsistent with activating/deactivating a
branch in the context-menu of a branch inset, and the previous code
assumed a workflow of the user, rather than letting the user
separate opening/closing branch insets from activating/deactivating
them.
This commit modifies fd6cd728.

When trying to do implement a LaTeX feature on screen, it is always
good to see how LaTeX does it, just in case it is easy to implement on
our side.
Then we have a correct output at all DPI sizes.
With RtL text, the method can be non-monotonic wrt x value (which is a
Qt bug). To work around this, we check whether positions adjacent to
those returned by xToCursor look better. Depending on whether the new
x position is too small or too large, we look backward or forward for
a better solution.
The performance is probably not great, but this is only needed for
user interactions, so the performance penalty should not be a problem.
Fixes#10569.
Rephrase positively the check box for the output of en- and em-dashes
and disable it when using non-TeX fonts. The state of the check box
is remembered, so that toggling the non-TeX fonts check box does not
cause information loss.
This commit fixes the regression introduced in 2.2 about the
output of en- and em-dashes. In 2.2 en- and em-dashes are output as
the \textendash and \textemdash macros when using TeX fonts, causing
changed output in old documents and also bugs (for example, #10490).
Now documents produced with older versions work again as intended,
while documents produced with 2.2 can be made to produce the exact
same output by simply checking "Don't use ligatures for en-and
em-dashes" in Document->Settings->Fonts.
When exporting documents using TeX fonts to earlier versions, in order
to avoid changed output, a zero-width space character is inserted after
each en/em-dash if dash ligatures are allowed. These characters are
removed when reloading documents with 2.3, so that they don't accumulate.
Introduce a distinction between being read-only and having the read-only flag. A
buffer is read-only if either it has been externally modified or if it has the
read-only flag.
Coverity does not find it obvious that p is never negative. Normally
it is the case (because the items have been filtered), but it is
better to play safe.
Instead of using a coverity annotation (that does not work) it is
better to really iinitialize the members of the object, just in case
somebody decides to actually use the DisplayPath() constructor.
It extended QToolBox with size calculation to fix UI issues with the previous
design of GuiCitation. Since it always needed some kind of hack and since
QToolBoxes do not appear so popular, it probably won't be used anymore.
Useful to cache copies of objects, including shared_ptrs. No risks of dangling
pointer, and avoid naked pointers in the source.
Fix memory leak when compiling with Qt5.
The current version was wrong for non-English dialogs, and even for
the English one, due to the translator commands that were not removed
for calculation (as in "Formats[[output]]").
Candidate for stable.
This adds support for the chapterbib package, but also adds ways to
produce this sort of multibib with biblatex and bibtopic (which are
both incompatible with chapterbib).
File format change.
File format change.
This allows for the relevant InsetCommand-based dialogs (such as
citation text before/after, Bibitem label, hyperlink name etc.)
to provide both the input of verbatim code or text that is transformed
to proper LaTeX code.
Some dialogs (Nomencl, Href) already had some methods (although they
could not be toggled), which are now centralized and streamlined.
The initial work of this patch has been done by Georg Baum (see
http://www.lyx.org/trac/attachment/ticket/2751/x.diff)
Fixes: #2751, #8227.
Starting with Qt 5.6, setting the environment variable QT_SCALE_FACTOR
makes everything accordingly bigger. So, if QT_SCALE_FACTOR=1.2, all
text and GUI elements are rendered 20% bigger. However, if an application
does not account for this, everything will also look "blocky".
With this commit, all text and images will be scaled remaining sharp.
This works whether a HiDpi screen is used or not, but is mostly useful
with a HiDpi screen, as all GUI elements are more spaced apart and one
can use the mouse for selecting things without requiring a high precision.
These are biblatex-specific multicite commands that allow for multiple
pre- and postnotes, as in:
\cites(pre)(post)[pre1][post1]{key1}[pre2][post2]{key2}...
with an optional general pre- and postnote, which applies to the whole
list (like [][] in normal cite commands) and an optional pre- and
postnotes for each item, so that pagination can actually be specified in
multi-cite references, as in:
(cf. Miller 2015, 2; furthermore Smith 2013, 23-23; Jenkins 2012, 103,
also refer to chapter 6 in this book)
See the biblatex manual, sec. 3.8.3., for details.
File format change.
It seems that QTextLayout does not handle properly a single character
with 0 width. This breaks drawing of things like \not.
Actually the problem had been worked around already in lib/symbol. The
work around can therefore by removed now.
[additionally, remove extra spacing from \mapsto, \Mapsto]
Fixes missing outliner names in various situations. Now if the warning "Missing
outliner name" appears in the console, this correctly hints at an actual issue
with the layout.
Biblatex can be used with Japanese, but then, biber (not pbibtex) should
be used as processor.
I this context, bring the jbibtex UI in line with bibtex, allowing for
a selection of alternatives.
This is now set as default. It selects biber for Biblatex (with
fall-back to first bibtex8, then bibtex, if the former is not
installed), and bibtex for BibTeX-based engines.
With this, users do not normally need to care for the processor when
they switch cite engines.
inset.
If the reference is "sec:mysec", then this will output just "mysec".
This is what is needed, e.g., to use refstyle's range commands, e.g.,
\secrangeref{mysec1}{mysec2}
You *cannot* use:
\secrangeref{sec:mysec1}{sec:mysec2}
even if those are the actual labels.
Eventually, I'd like to add native support for this, but I'm a bit
frightened of trying to make the reference dialog support multiple
selections.
This entails a change of getAbbrAuthor to getAuthorList (the default is
still abbreviated with respect to MaxCiteItems, but the list can be, at
explicit request, shortened or full notwithstanding MaxCiteItems.
Next to the cmd name, introduce optional latex names (that might differ
from the cmd name) and aliases (that are "obsoleted by" the cmd).
This enhances portability between the engines.

The root of the issue is in Buffer::reload() called during "Save As". After
loadLyXFile() there, all the insets have been deleted, and therefore the Inset
pointer GuiView::documentBufferView()->cursor().inset() is dangling. Immediately
after loadLyXFile(), reload() calls updateBuffer() which causes a segfault.
While debugging I got other segfaults caused by the same dangling Inset pointer
in Cursor, notably: 1) a trace identical to the second one from
<http://www.lyx.org/trac/ticket/10520>, and 2) a similar segfault in the
critical path after emergency saving (call to inMathed()).
Having to "refresh" by hand the inset pointer cache in CursorSlice is very
unsatisfactory, but there does not appears to be a consistent strategy for
managing these Inset pointers in CursorSlice.

Subject: [PATCH] Add "Swap & Reverse" to math delimiter dialog
When "Keep matched" is unchecked, a button becomes enabled to "Swap &
Reverse" the left and right delimiters. This is expected to be of use
with line-wrapped equations featuring one or more set of delimiters that
break across the lines. When "Keep matched" is checked, the button is
visible but disabled.
The most common use case is expected to be the user entering a pair of
unmatched delimiters on the first line of an equation (e.g., "(" and
"(None)"), entering the inner text, going to the next line, and
inserting the opposite set of delimiters (e.g., "(None)" and ")").
This button will negate the need to find the correct corresponding
combination. However, it relies on the dialog's memory of the previous
unmatched set.
This change addresses Ticket #10457
-----------
Modifications by spitz to the original patch:
* Only enable the button if an unmatched pair is selected
* Consider l7n when locating the string "(None)"
* Add an accelerator and a tooltip to the dialog
* Simplify the code a bit
* b `british' (``inner quotation'')
* w >>swedishg>> ('inner quotation') ["g" = Guillemets]
* f <<french>> (``inner quotation'')
* i <<frenchin>> (<<inner quotation>>) ["in" = Imprimerie Nationale]
* r <<russian>> (,,inner quotation``)
Rename "french" to "swiss"
Also rename "single/double" to "secondary/primary" ("inner/outer" in
the UI) and "left/right" to "opening/closing". Note that the inset
identifier string is left as is ("s/d" and "l/r")
The current char-based implementation gets increasingly unreadable,
especially if styles are added that do not follow the strict
single-double paradigm.
The QTextLayout handling is terribly slow on Qt 4.8.7, but some
caching has been added in Qt5 that makes it much faster. For some
reason, it is not that slow with Qt 4.8.1.
Caches are introduced for the three following methods
* width(doctring), controlled by CACHE_METRICS_WIDTH. This cache already
existed, but the code has been cleaned up
* getTextLayout, controlled by CACHE_METRICS_QTEXTLAYOUT (disabled by
default on Qt5, which does its own caching). This is used for pos2x
and x2pos and now for drawing of text too. The previous code used a
trivial caching scheme of the last used QTextLayout, but now they
are properly kept in a QCache. Moreover, the cacheEnabled() property
is enabled for these QTextLayout object (not sure what this does).
* breakAt, controlled by CACHE_METRICS_BREAKAT. This is the only user
of QTextLayout which did not have some kind of caching already.
For some weird reasons related to Argument-dependent look-up, the
qHash(docstring) function has to be defined in std namespace, since
lyx::docstring is actually std::basic_string<wchar_t>.
[NOTE: this version has profiling hooks, enabled by commenting out the line
#define DISABLE_PMPROF
that should eventually be removed.]
It may happen (for example with on the fly spell checking) that
GuiFontMetrics::pos2x is called with a negative pos value. Add a
special case for this situation.
Fixes bug #10506
* endInsertRow was incorrectly placed before endResetModel, sometimes leading to
bad access by the view before it was informed that the model was empty. In
fact begin/endInsertRows were redundant with begin/endResetModel.
* Empty blocks are not supposed to be shown. This happened when moving the
cursor. A valid block is now selected intead. Due to the design/optimisation
of the model update, this requires a first update with an empty
model. Simplify the old code.
- Allow using logical values for icon sizes as the standard sizes may
differ among different icon sets
- Do not allow setting sizes smaller than smallIconSize
When the logical sizes differ and the icon set is changed, the correct
sizes are established only after a restart.
Addressing #10481.
This patch adds the new 'needauth' option for converters launching
external programs that are capable of running arbitrary code on behalf
of the user. These converters won't be run unless the user gives explicit
authorization, which is asked on-demand when the converter is about to
be run (question is not asked if the file is cached and calling the
converter is not needed).
The user prompt has a 3rd button so that he/she's not prompted again
for (any converter over) the same document (identified through
buffer->absFileName()).
Two preference options are added:
lyxrc.use_converter_needauth_forbidden disables any converter with
the 'needauth' option, which is meant to force user to an explicit
action via the preferences pane, before being able to use advanced
converters that can potentially bring security threats;
lyxrc.use_converter_needauth enables prompting the user for 'needauth'
converters, or bypasses the check if not enabled, falling back to the
previous behavior.
So, the first option is for maximum security, the second is for
maximum usability.
- Adds LFUNs for setting the icon size
- Adds icons sizes to the Toolbars menu
- Uses the Toolbars menu as application context menu
- The context menu can now be user defined in stdcontext.inc
Fixes ticket #10428.
Move math style to FontInfo and compute the font sizes for scriptstyle and
scriptscriptstyle according to standard proportions: 0.73 and 0.55.
This is simpler and more accurate. It also fixes the font size of
${\scriptscriptstyle {\textstyle A}}A$ which exposed the limitations of the
previous approach.
An overlong word containing a hyphen could be broken anywhere, instead of after
the hyphen.
Example: compare the line breaking of
aaaaa-aaaaa-aaaaa-aaaaa
with
aaa aaaaa-aaaaa-aaaaa-aaaaa
(with a very narrow window)
This also improves Chinese text in some situations (#10299)
1) Distinguish expanding characters from separators, to fit with Qt's notion of
expanding character which comes from the Unicode std. CountExpanders() is moved
to FontMetrics to fix a discrepancy with the duplicate implementation from
598f7e4a.
2) Make these expanders stretch on-screen proportionally to the em of the font.
If a row mixes large and small text, LyX let us see which spaces are set in the
bigger font.
3) Now that the stretch is defined in ems, add a limit such that an expander
never stretches more than 1.5em to avoid weird and hard to read justified lines.
4) Add a return boolean to setSeparatorExtraWidth for future use.
It turns out that Cursor::getFont() does not return a fully realized
font in some cases. This patch uses real_current_font instead, which
seems better anyway.
I suspect that all uses of getFont() should be removed, but this is
not code that I know well.
Fixes bug #10478.
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.
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.
