* set up a replacement of *, -, and : by the adequate symbols (#9893)
* fix the wrong character selection and operator spacing in \text mode
* hide some internal symbols from the auto-completion.
* Fix spacing in lib/symbols after recent commits about math spacing, as well as
older spacing issues (e.g. \Join).
* InsetMathKern now uses the same em value as other math length commands.
What is nice is that the kerning amount now matches the ones found in the
packages definition (modulo 10mu that lyx currently adds between relations).
Testcase: $\CheckedBox\LEFTcircle\RIGHTcircle\photon\gluon\vcentcolon\dblcolon\Coloneqq\eqcolon\models\hookrightarrow\bowtie\hookleftarrow\Join\APLinv\neq$
When \multicolumn{ncol}{align}{content} is parsed and the ncol
parameter is not a numeric value, this parameter is swallowed
and replaced with '1'. Hence, if the file is subsequently saved
a dataloss would occur. With this commit, \multicolumn is not
interpreted when ncol is not a numeric value and is left as is.

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.
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.
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.
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.
* 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)
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.
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.
It may happen that mathedWordList is not still updated at load time,
so we would still be using a bogus pointer. Better fetching the
necessary info from the global macro table.
The math macros system is quite complex. Macros are updated during
metrics calculation, so a missing update is very likely to cause a
crash. This commit tries to assure that they are updated at export
time, which also happens when the table of contents is updated.
Moreover, in order to circumvent a possible missing update, when
a math macro is detected we try to avoid using the sym_ member
of the MacroData class, as it may contain bogus values.
If the first character in the first cell of an aligned math environment is
'[', and the environment does not use top or bottom vertical alignment,
then LyX did write the '[' unprotected so that it got misinterpreted as
optional argument, both when reading the .lyx file in LyX and when reading
the .tex file in LaTeX => data loss!
The fix is to output an empty optional argument in this case, which is
interpreted as default alignment both by LyX and LaTeX. It would also be
possible to output \[ in the first cell instead, but this would be more
difficult to implement.
The \multicolumn command allows to set vertical lines for individual rows.
These are not yet displayed, but if they are supported one day, the code in
a27ff13663 needs to be adjusted. This change hints at the adjustment.
This is a fixup to commit 39329935. The two fixes are
* add forgotten offset `y' when drawing the line
* in order to have a continuous vertical line, draw from the offset of
the previous row.
Fixes bug #10363.
Now by default all insets paint their own background when needed. This
means that 63cf3297 and part of 9940acc5 can be reverted.
To avoid extra painting, background drawing is disabled for
InsetCommand and InsetCollapsable. These insets draw background as
part of their normal drawing activity.
This will avoid drawing artifacts with InsetNewpage, InsetVSpace and
probably some others.
For reference, the bug was that quote insets grew bolder because, when
painted over themselves, anti-aliasing made them darker.
It turned out that the fix there created others than were
painstakingly fixed: #7164, #7165, #7174, #7193... More recently, it
created other problems:
http://article.gmane.org/gmane.editors.lyx.devel/163471
We use the right fix here:
* draw background of quote inset when not doing full repaint
* draw background of math macro template when not doing full repaint
* remove hack that grew from #4889 fix.
This is the well known file locking problem: The TempFile class keeps the
created file locked for the own process, and this prevents the CAS to read it.
