Consider mathbin, mathrel and mathpunct as word separators. This makes
Ctrl+{Left,Right} more intuitive, quicker, and more different from {Left,Right}.
This takes into account all the feedback from the discussion on the general
list. Further feedback welcome.
Now backspace and delete in text will select non-empty math and text insets
before deleting them. This is consistent with what happens in math already.
This is implemented for InsetText as well but can be disabled in case of
negative feedback.
This can be set for any sort of inset with the new virtual method
Inset::confirmDeletion.
New option "force" for the LFUN_*_DELETE_* commands, that bypasses the
confirmDeletion check.
This allows to somewhat simplify the text and avoid some uses of
Paragraph (in the long term, RowPainter should not have to access
these things).
At the same time do a small cleanup to RowPainter: rename
text_metrics_ to tm_, remove pm_ and width_.
Following discussion on the list:

This defines a new behaviour for Ctrl[+Shift]+Arrow in math:
* Left/Right does not enter insets
* Left/Right jump groups of insets that have the same math class ("words")
* Enable Up/Down for consistency.
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.
On export, a macro defined in ERT (or not defined at all) is left
in the same environment it is entered. So, don't explicitly insert
it in an ensuremath environment when it is entered in a textmode one.
A math-mode command entered in a text-mode environment is wrapped
in an ensuremath inset, as well as a text-mode command entered in a
math-mode environment is wrapped in a text inset. Who doesn't like
the extra insets can always dissolve them and rely on the wrapping
performed on export.
The old name would be confusing wrt setSelection(), which does additional checks.
This one is a pure acessor, and the more complete methods are
* setSelection(), which avoids empty selections
* clearSelection(), which resets anchor, and sets word selection and mark more to false.
Most of the code should use these two instead of selection(bool), but this is for later.
(#8738)
For efficiency, we add a new flag to the buffer indicating when changes are
present. This flag is updated at each buffer update, and also when explicitly
requested via a dispatch result flag.
Improve the test whether cursor has moved in Cursor::posVisLeft. The code for posVisRight had already been fixed for #5764 at 0730c923, but this replaces both tests by the proper == operator.
Fixes bug #9913.
WriteStream is now built from an otexstream instead of an odocstream, and
therefore counts lines in a TexRow. Calls to TexRow are added in relevant places
in math insets.
This finishes adding line tracking for math in the source panel and for forward
search.
The id is just the memory address.
The status bar now spits out the math inset uid information when in a math cell
in DEVEL_VERSION, like it already does when in a paragraph.
This is preliminary work for extending the cursor<->row tracking to math.
This removes the old implementation of Cursor::getSurroundingPos, that has been superceded in commit .
As this was the last user of the Bidi class, this can be removed too.
New method TextMetrics::findRowElement, excerpted from CursorX.
Reimplement getSurroundingPos using Row information. This is easy when
the cursor is inside a row element. At row element edges, different
situations can occur; hopefully all these situations are taken into
account.
Rename the old getSurroundingPos to getSurroundingPosOrig and
transform getSurroundingPos into a wrapper that compares the two
methods. This will be removed when we are confident that the new
function is equivalent to the old one.
It will then be possible to remove also the Bidi class (at last!).
With this patch, the cursor position before undo can be saved when
creating an undo group. Any such value will supercede parameters
passed to recordUndo. Only the first such cursor set by nested
beginUndoGoup takes effect.
Fixes bug #9663.
The functions reverseDirectionNeeded() and reverseDirectionNeeded() do
not rely on the Bidi class. The first one is changed into a Cursor
method, and the second one is replaced with explicit code.
Currently, insets are notified that the cursor entered or leaved them in Cursor::dispatch. This is not the cas efor lfuns which are handled in BufferView.
Adding the proper code allows to fix many bugs where previews are not updated correctly.
This also reverts cf4f79f8, which was the same fix for a particular case.
Fixes bug #6173.
The cleanup in 11ca1406 was not correct. It is actually not possible to implement recordUndoInset from the undo API, since the cursor may not be at a different level than the text to be saved.
Fixes ticket #9553
