(#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This removes the old implementation of Cursor::getSurroundingPos, that has been superceded in commit .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
Newer boost versions use complicated type traits for boost::next and
boost::prior, which do not work with the RandomAccessList iterators.
The long term solution is to use std::next and std::prev, for now supply
simple replacements for compilers that do not support C++11 yet.
* Remove the UndoKind parameter in the general interface
* move recordUndoInset to Cursor
* remove one variant of Undo::recordUndo.
* get rid of Text::recUndo.
Additionally, move the code to write to a stream from Cursor to CursorData (so that debugging undo is easier). We loose x_target, but I am not sure it is important.
This is the second part of bug #9432.
Rename recordUndoFullDocument to recordUndoFullBuffer.
Separate the notion of recording changes to paragraphs and recording changes in buffer parameters.
Audit every user of recordUndoFullDocument and replace it with either recordUndoBufferParams or recordUndoFullBuffer. Add comments to identify remaining work.
* remove unused class TexStream.
* remove unused virtual method Inset::cellXOffset
* remove second argument of FileDialog constructor, which was actually
not used
* remove some dead local code
* remove some unused private members of classes
* in InsetMathNest::updateBuffer, fix the logic of a test
The code that checks whether the cursor was at the end of a row in
Cursor::upDowninText was not able to set boundary correctly. This
causes a hang in because the cursor got stuck on a line and there is an
infinite loop BufferView::dispatch when trying to go down.
The fix is to avoid using the watered-down TextMetrics::x2pos wrapper
around getColumnNearX and use the real thing instead.
Eventually, the last user of x2pos (InsetTabular) should be fixed and
the method should go away.

This commit does a bit more than fix selection, since it saves the full cursor state
in the undo stack. This means that undo now restores:
* the selection
* the current font
* transient mark (shall we keep this one?), logical position...
In order to do that, it introduces an intermediate class between Cursor and DotIterator: CursorData.
The new inheritance diagram is thus
DocIteraator -> CursorData -> Cursor
CursorData contains all the members of Cursor that define the current position, but not the stuff
related to current view of dispatch mechanism. It may make sense in the future to move members
between CursorData and Cursor and to move some member functions to CursorData.
Now UndoElement uses CursorData for cur_before and cur_after, but not for the cell. The undo API uses
also CursorData instead of DocIterator.

* Undo.cpp:
- rename cur member of UndoElement to cur_before
- add new member cur_after, which is set by Undo::endUndoGroup
- create a new Undo::endUndoGroup variant that takes a Cursor as parameter. We cannot get rid of the old one because it is used for LFUN_COMMAND_SEQUENCE.
* Cursor.cpp:
- use endUndoGroup(Dociterator const &) for dispatch
- update Cursor::endUndoGroup to pass cursor.

we will be cautious, of course). The problem was that we were issuing
the Buffer::changed() signal before we did updateBuffer(), and this
caused an inconsistency. The idea here is to defer issuing this signal
until we call processUpdateFlags(). We know we need a redraw if we've
deleted a whole paragraph.
This should work properly, so long as checkDepm is called from within
the dispatch mechanism. There may, however, be other paths, and I've
noted one explicitly with a FIXME in Text2.cpp. I've tested a few
different variations, however, and I haven't seen any problems. But if
we do run into problems, we can go ahead and do the update there that we
were previously doing in checkDepm itself.
