This fixes the "bad keming" of math ERT (in fact wrong metrics) which recently
was worsened by InsetMathChar substitutions and their MathClass spacing.
Also fix a small inefficiency: always prefer:
Changer dummy = (currentMode() == TEXT_MODE)
? pi.base.font.changeShape(UP_SHAPE) : Changer();
over:
Changer dummy = pi.base.font.changeShape((currentMode() == TEXT_MODE)
? UP_SHAPE : pi.base.font.shape());
The former only records and restores a value when the condition is satisfied,
and does not cost anything otherwise.
- 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.
MiKTeX made a major package cleanup during the last 2 weeks. (Which caused a lot of troubles btw.) Many packages were removed and renamed. Now the list is complete again.
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.
The current math style should have no impact on \kern1mu. This is another
benefit of a9eb87a8.
Testcase:
\begin{align*}
& \kern1em a\\
& {\scriptscriptstyle \kern1em a}\\
& \kern18mu a\\
& {\scriptscriptstyle \kern18mu a}
\end{align*}
- 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.
In fact having an extra parameter "bool cond" is no longer useful because it can
now always be emulated with a ternary operator:
Changers dummy = cond ? do_change() : Changer();
* Factor code for easier maintainance.
* Avoid computing metrics several times. This duplication explained the
exponential blowup during the metrics phase for nested fractions (see
b2b87330). This happened in particular when using lyxproofs which heavily uses
nested \dfracs for on-screen drawing.
* Call MetricsBase::changeScript instead of MetricsBase::changeFrac for
\nicefrac and \unitfrac.
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.
The purpose of this branch is to improve the spacing in math equations
* do not use hardcoded pixel values, but math units that depend on
zoom and dpi. This should be good for HiDPI systems.
* implement as much as possible the math typesetting algorithm
described in Appendix G of the TeXbook.
One typical example of the spacing algorithm is that ``-a'' has no
spacing, contrary to ``a + b''. This reflects the unitary/binary
minus that will indeed happen in typeset output.
Together with the better character substitution that has already been
implemented by Guillaume, we get a nice improvement of mathed looks.
What makes this code complicated is that it handles macros properly:
the spacing inside the macro will depend on the values of the
arguments and the elements that are before and after the macro.
As a result, many definitions in lib/symbols are now just copy/pasted
from the relevant sty file. In particular, it is now possible to make
use of \mathrel, \mathbin, etc. macros to specify spacing.
This merge is a starting point. Remaining work includes
* proper handling of sub/superscript nucleus and of font-changing
insets (as is done in the TeX algorithm).
* proper typesetting of fractions
Thanks to Guillaume for extensive testing.
Try as far as possible to use the same definitions as in the LaTeX files.
An example of that is the definition and subsequent use of \joinrel,
\relbar and \Relbar.
This is mostly Guillaume's work.
There is no reason to reserve pixel space in macros replacement text,
which is not editable. This makes macros more compact and eases the
writing of lib/symbols.
* introduce new InsetMath::drawMarkers and friends that do nothing
when nested inside a macro. This required to move macro_nesting
inside MetricsBase, and to pass MetricsInfo & to metricsMarkers.
* keep track of nesting when drawing rows or macros.
Empty insets should use a minimal amount of space, especially when
they are part of a built-in macro in lib/symbols.
With this change, blue rectangles signal actually editable places.
Empty macros in editable data are shown as grey boxes, but they do not
appear when further nested.
This is done by adding a new type BOX of MathRow::Element object and a
MetricsInfo::macro_nesting that keeps track of macros (and is reset to
0 in editable macro arguments).
* new MathRow class which contains the description of a MathData
object in terms of math class and spacing
+ macros and their arguments used in the MathData object are
linearized (replaced with their contents) so that all math insets
are typeset as a string together. To this end, we introduce a
method addToMathRow to InsetMath and MathData. This method allows
to linearize recursively a MathData object.
+ It is then necessary to set manually the dimension and position of
the macros and arguments.
+ the class class and spacing are computed using the MathClass helpers.
The MathRow data is cached in the MathData object in a bufferview-dependent
way (different dpi for different screens).
* delegate most of the work MathData::metrics/draw to MathRow metrics/draw.
The case of draw is trickier, since many draw() methods rely on their
metrics without any spacing added.
