Before this commit, navigating with the cursor was visiting either
the nucleus or the script depending on the direction (left or right)
of the cursor movement. Now the 2.3.x behavior of always going through
the nucleus is restored (at least for overset and underset, as stackrel
seems to behave oddly also in 2.3.x).
Also added missing math env alignat
Modified handling of longtable/tabular
Added a routine to count for valid chars. This is needed
for detection of word boundaries.
Due to detection conflicts
regex '.*' vs match of word-boundaries in MatchStringAdv::operator()
we need to use '\b' in regex explicitly. E.g. '\b.*\b'
The backward search works, but
1.) only in current paragraph (this is the same as before)
2.) only in the same language environment.
1.) Added \textmd to be ignored (sometimes it is used and sometimes not)
2.) Typo: multiline --> multline. Searching in 'multline' caused a crash
because processing all of the '{' and '}' in the content of this math
exceeded the size of the interval field.
1.) Handle some unclosed parentheses
Sometimes \shortcut is not correctly closed
2.) Added \ldots as known char
3.) Discard some shapes (circlepar, droppar, ...)
4.) Omit resulting empty string and use some value
which cannot be matched instead
This is a follow up to 503c7c16.
The new argument for placing cursor after insertion of inset is:
* if inset has no cell, do nothing
* otherwise, place inset in entry cell.
+ if entry cell is not empty (we pasted a selection), go to next cell
+ if this next cell does not exit, stay after the inset.
That way we do not match the whole table but only the cell contents.
The problem I had was
1.) Document language Spanish
2.) Table (copied from English doc) => language English
3.) All cell contents Spanish
Now search for English text led to a selection of the whole
table, although there was no English content in any cell.
With Qt 5.11 at least, RtL text will be drawn RtL even when the
(undocumented) flag Qt::TextForceLeftToRight is applied to the
QTextLayout object. This creates selection issues for Hebrew text
marked as English.
The solution is to do the same as in breakAt_helper, that is prepend
the string with a direction override unicode character.
Doing this requires to introduce a TEXTLAYOUT_OFFSET constant that has
to be used wisely to account for this extra character.
Fixes bug #11284.
The problem was, that the different list ennvironments
did not look different in tha latex output used for
search.
So the input of "\item ..." did not give information
if it is description, lyxlist, enumeration or labeling.
In search modus we use now "\item{enumeration}" etc.
Exception: findadv-21, but it is not a regression,
because this one never passed.
The problem here is, that we cannot differentiate
between enumeration, itemize, description and labeling
environment here.
Now tests findadv-01 ... findadv-20 pass too.
keytest.py: Expanded time for controll keys (like \[Return])
findadv*: expanded time for normal keys
lyxfind.cpp: Handle math equations
