LyX removes a single backslash when it is inserted in a
macro name by the keyboard. However if it is followed by
another character before moving the cursor, it is retained
causing an assertion (bug #12601).
Disable the arguments append-column and delete-column of tabular-features.
The code is taken from InsetMathCases, with some changes
* no need to record undo here
* in dispatch, return is prefered to break, since we do not want to invoke
InsetMathGrid::doDispatch.
Propagate these changes to InsetMathCases.
Cleanup of the InsetMathCases error messages to fit with other parts
of the code.
The handling of tabular-features in mathed needs to be unified somehow.

Part of bug #12590.
Backslashes are not allowed in macro names and LyX
enforces this by not allowing entering them by keyboard.
However, it was possible to paste them and this may cause
crashes (see bug #12596).
The previous code explicitly disabled it and this behaviour caused problems (like "A&A" being output as-is, which is wrong in HTML: it should be "A&A").
It appears that gcc 4.9 does not implement the following part of C++11:
https://cplusplus.github.io/CWG/issues/1148.html
Therefore, we have to use a special case in C++11 mode that does an
explicit std:move.
With recent compilers (gcc >= 9), this leads in C++11 mode to a warning:
MetricsInfo.cpp: In member function ‘lyx::Changer lyx::MetricsBase::changeFontSet(const string&)’:
../../master/src/MetricsInfo.cpp:83:13: warning: redundant move in return statement [-Wredundant-move]
83 | return move(rc);

MetricsInfo.cpp:83:13: note: remove ‘std::move’ call
Partly reverts commit fff28c57.
This branch improves handling of spaces on display (see #10117):
* caret is correctly shown in the middle of double spaces in justified rows;
* sequence spaces are correctly shown at the end of rows before
automatic row breaks.
Moreover, this branch:
* streamlines the code that handles spaces in row breaking
* improves display in Qt4 : although the improvements outlined above
are not present in Qt4 for monospaced fonts, some dsplay glitches
are resolved.
* improves performance for very long paragraphs (#12598).
When is it detected that our zero-width characters are not really
zero-width, avoid to use them altogether. Currently, this is known to
happen in Qt4 with monospace fonts.
This allow to remove the special Qt4 code in breaskString_helper.
Related to bug #10117.
This allows to create a new version that takes an already built
TextLayoutHelper struct as parameter.
No intended change.
See discussion in bug #10117.
In order to work around the Qt row breaking algorithm, which considers
multiple spaces as one at QTextLine break, we insert word_joiner unicode
characters beteween each pair of spaces.
The TextLayoutHelper class makes it easy to handle that.
Update Row::Element::rtrim() to only remove one space at row end.
Update support::countExpanders() to count all spaces, without special
handling for consecutive ones.
Fixes bug #10117.
This new code allows to get rid of some hardcoded stuff and will be a
foundation for handling of consecutive spaces.
This code can be used in the future for getTextLayout, x2pos, and
pos2x in order to streamline code. Actually some features as the naked
parameter are here to prepare for this second set of changes.
No change intended. The modified code is much clearer, though.
Related to bug #10117.
When there is no module, the old code would invoke tex2lyx with option
-m
instead of
-m ""
and an error would ensue.
This is because the QProcess command line parser used in Systemcall is
broken and does not recognize empty parameters as such. The solution
is to rewrite our parsecmd() parser to generate a list of parameters.
This is post-2.4.0 work.
The workaround used here is:
- set the list of modules to "," when it should be empty. In effect,
this is a list of two empty modules.
- change tex2lyx to accept empty module names and ignore them; this is
good in terms of robustness anyway.
Additionally, when there is no receiving buffer, set the defaults as
the BufferParams defaults instead of empty (this is cleaner, but
should not make a difference in practice).
In the long term, we should switch to use the QStringList-based API of
QProcess in Systemcall (see QTBUG-80640).
This is a convenience function for indexing. It adds a copy of the
index inset under cursor after any word in the buffer that is equal
(case-insensitively) to the word preceding the index inset.
The function can be easily used to generate bad indexes (and I warn
about that in the UserGuide), but if used with care, it can also be
extremely convenient.
Previously, only the suggestions starting with the current input were
shown.
Contains the following minor improvements:
- Add space to indicate when only one suggestion is found
- Select first item in suggestion-list in order to make selecting with
arrow keys more intuitive
- Fix selection with Shift+Up/Down in text-field
Fix for bug #12572.
The new function inset-insert-copy can only be invoked from the ToC.
It is currently only implemented for Index inset.
It is a special lfun because Inset::dispatch is called directly from
the ToC widget with cursor pointing to the inset, whereas the patch
happens in the workarea at caret position. This function cannot be
called directly.
Add an entry for this function in the toc context menu.
Fixes bug #4582.
The change ensures that the function is not seen by the compiler when
the debug mode is not enabled. The flag is not set by default, because
it might have a significant performance impact for large indices.
The reason for the flag is that the default configuration under Linux
forbids the definition of unused functions.
