A reference can be directly inserted into mathed but cannot be pasted
because the pasted material is returned in plain text format. This patch
allows getting a string from the cut stack in a suitable format allowing
the math parser to actually create an InsetRef.
Fixes#11539
It turns out that the code is the same in texted ans mathed and that
whatever is done in InsetTabular is not useful.
This means that we do not need to deal Text::dispatch idiosyncrasies
(in particular forcing the cursor to be visible).
Fix bug #11225.
If a macro has only optionals and none is specified and a [ immediately
follows, we have to terminate the macro with {}, otherwise what follows
is taken to be an optional argument.
Fixes#11665.
The ensuremath math inset derives from InsetMathNest, so that only the
first cell of a grid gets pasted. This patch makes it a fixed 1x1 grid
inset so that pasting works as in normal simple math hulls, i.e., all
cells are pasted, one after the other.
Fixes#11617.
At the moment, there is no support for plurals and capitalization.
A long comment explains why. Support could be added for that without
a format change.
Since we are not sure of where the cursor ends up after invoking
Cursor::handleNest it is safer to reset the cursor at each cell,
rather than reuse the same one over and over.
Related to bug #12035.
- Add limits support to InsetMathScript
- Add limits support to InsetMathClass
- Fix bug where limits changing is disabled in inline math
Now the MathData objects remember whether they are in diaply mode.
Fixes bug #12045.
The problem here is that the check against TEXT_CODE only
catches InsetText, and not its subclasses. Same for the check
against MATH_HULL_CODE. So there is reason not to check codes
here.
This reverts commit 5a54ccfa87.
Setting the res value and returning from the function at the same time
does not make sense. After reflection, it is the "return" that shall
go.
No idea what effect it had.
The macros defined in the symbols file are only used for on-screen
representation, so that their definition should not require the use
on any latex package. Their definition should be taken into account
only when they are overridden by user macros with same name.
Move InsetMacro::limits_ to InsetMacro::Private, where it should have
been from the start. This means that limits_ is now copied when the
macro is cloned.
This extra spacing was missing and is important for detecting extra
par breaks before equations (which are most of the times not wanted).
To do that, add a new member vmode to MetricsInfo which is equivalent
to LaTeX's \ifvmode (start of paragraph).
If in vmode, add the equivalent of an empty line before a display math inset.
At the same time, tweak value of \(above|below)displayskip, which was
12pt, whereas LaTeX uses 10pt in 10pt size (our reference).
Fixes bug #11891.
Since be836909c5 the positioning of super- and subscripts
for symbol fonts has been broken because the metrics of the
font of the environment (rather than those of the symbol itself)
were used.
These are now properties of insets that can be operators :
InsetMathSymbols, InsetMathDecoration (for over/underbrace) and
InsetMathMacro (for its contents).
Each of these has a limit_ member that allows to remember a limit
forcing and a member defaultLimits() that indicates what to do in the
absence of such forcing. Moreover the write() method calls
writeLimits().
This allows to simplify the definitions of integrals in lib/symbols by
defining the integrals as macros of their "op" version, as it is done in
the style files.
Also, many hardcoded assumptions can now be removed.
The handling of LFUN_MATH_LIMITS is now done in InsetNest, which tries
successively to apply the limit change to (1) the character after
cursor, (2) the character before cursor and (3) the character at the
end of the inset (useful for script insets?)
The new code allows to define
\newcommand\int{\intop\limits}
but not
\newcommand\makelimits#1{#1\limits}
It is also possible to type explicitly \limits or \nolimits to modify
a symbol.
The goal is to reproduce the change of size of operators like \sum wen they
are in display style.
The syntax of the symbols file has been extended to allow for two code
points (like 80|88 for \sum). In this case, the second one will be
used in display style.
Update the symbols file to handle all bigops from cmex, esint, wasy and
stmaryrd.
Let the code for math symbol inset handle symbols which can change size,
using the information from the symbols file.
The old code in GuiPainter::filterColor did not work. Tricks with
colors should take place in HSV space, not RGB IMO.
Replace the code with a simpler one which maps the grayscale value
of the original color on the blend color. It works nin the case where
original color is red, but might not work as well when blend color is
not black. Time will tell.
Fixes bug #11904.
The enum DisplayType is replaced with the flags RowFlags that can be
combined. Here is the correspondence between the old DisplayType and
the new Inset::RowFlags:
DisplayType RowFLags Meaning
Inline Inline plain inline inset
-- BreakBefore row ends before this inset
-- BreakAfter the row ends after this inset
AlignCenter Display the inset is centered on its own row
AlignLeft Display | AlignLeft the inset is left-aligned on its row
AlignRight Display | AlignRight the inset is right-aligned on its row
-- RowAfter an extra row is needed after this inset
Display is just a shortcut for BreakBefore | BreakAfter.
The flags for the newline inset will be BreakAfter | RowAfter,
while the separator inset will just use BreakAfter.
This groundwork does not introduce any new feature at this point. It
aims to remve the numerous isNewLine and isSeparator all over the
code, and to eventually optional break after some insets like spaces
(see #11621).
Most display() methods are renamed to rowFlags(). Some are removed
because they returned Inline.
Now display() is only a helper function for hull insets.
This commit adds the mathed command \mathds that selects a
font more appropriate than \mathbb for typesetting the
mathematical symbols for the natural (N), whole numbers (Z),
rational numbers (Q), real numbers (R), complex numbers (C),
and some others.
As in the \mathbb case, only capital letters are supported,
but in addition one can also typeset a symbol often used for
representing the indicator function (\mathds{1}) and the
letters a, h, k.
Fixes bug #11887.
It turns out that the resources were mostly not used anyway. Removing
them shrinks LyX binary by ~6MB.
Only autotools have been adapted. cmake will require the same
simplification.
It seems that the use of zoom in determining the size of the minimal
value was a bad idea.
It still think that the situation is not very satisfying, we need a new idea.
We tend to have insets which buffer() member is invalid. To help
debugging, this commit paints their background in red when devel-mode
is on.
To this end, a new method develMode() is added to the Painter class.
With this commit, it is easy to see that macro template do not have a
proper buffer set!
Make InsetGrid::colAlign a normal method and make it check whether
buffer is valid before using it. This avoids crashes as we have seen
in 2.3.3 (see e.g. #11686).
There is still an assertion so that failure is noticeable before release.
