All the code that is run before row metrics have been computed should use int arithmetic. After metrics have been computed, we still need doubles because fully justified rows use double for Row::Element::extra.
Rename Row::x to Row::left_margin and change its type to int.
Rename Row::Element::width() to full_width(). In some places of the code, use dim.wid (the int version without the extra separator) because metrics have not been computed.
Let Row::Element::x2pos take a int& argument instead of double&
Let Row::Element::breakAt take a int argument instead of double
The problem was that some parts of the code assume that the right margin is part of the width of the row. This is not the case, only the left margin (Row::x) is counted.
The code has been fixed and documented to reflect this.
This can only be done where splitting of string is identical in row breaking and display. It will be possible to reintroduce this when row painting uses the tokenized row information.
This variable was introduced to guard against any bad consequence of the then-new right-to-left
languages support. Let's be bold and get rid of it altogether!
Now right to left support is always enabled.
This commits (tries to) reintroduce properly the code that was reverted at the beginning of this branch. This had to be done because these patches interefered with the big refactoring of TextMetrics.cpp.
This commit reintroduces the changes to TextMetrics.cpp contained in c668ebf6, c85dbfea9 and 061509bf.
Moreover, breaks row at insets when there is no suitable separator.
Also make the code of Row::shorten_if_needed somewhat simpler by using
iterators and factoring the code.
Fixes: #9120
All these problems are related to what happens at the extreme points of rows
* since VIRTUAL elements have a width but no contents, they have to
be treated specially at some places. It would have been better to
avoid testing for them explicitly, but I did not find a way.
* Improve and cleanup the code in breakRow and fix in passing a crash
when clicking on the right of an incomplete MARGIN_MANUAL
paragraph.
* improve the computation of row width in TextMetrics::computeRowMetrics.
* handle properly the case where a position if not found on the row
in both cursorX and getPosNearX (actually, this happens when
selecting).
* Some code cleanup and comments.
* fix handling of boundary situations in Row::Elements::x2pos;
* fix handling of boundary situations in TextMetrics::getColumnNearX;
* make sure to always use Font::isVisibleRightToLeft instead of Font::isRightToLeft;
* Improve debug messages.
The horizontal position of the inset was not taken in account.
The rounding is not always the same as with the old code, but this
is not really important.
Additional changes:
* improve debug output of rows
* remove Bidi& argument of the RowPainter constructor, since it is always
an empty Bifi that is passed. This means that the Bidi class is not
used at all any more in TextMetrics.cpp. The only remaining user is
RowPainter.
Break words longer than the screen width. The code is more complicated
than I would like, but I have no better idea right now.
Implement properly the notion of a row broken by a display inset. This is useful in different places.
Also fix a bug with last line of a paragraph spotted by Kornel.
Use proper font everywhere for end-of-par marker
Fix getColumnNearX for RTL text and for centered/right-justified paragraphs.
Let computeRowMetrics update the row width.
* convert cursorX to new scheme; old computation is still there for the sake of comparison.
* use Row to compute separator width in computeRowMetrics; again, the old code is retained for now.
* Get rid of rowWidth()
* Row now contains a vector of Elements
* replace Row::dump by a proper << operator
* the width is updated as elements are added
* breakRow is reimplmented to use this infrastructure
Collect properly all strings to compute string metrics
Some changes with respect to existing code
- end of paragraph font is now the one of the text
- words longer than a line are not broken anymore. I think this is not useful if we have horizontal scrollbar
Other than that, the code is still compatible with rowWidth and friends.
Do not assert if an inset separator is the only item of a List
environment. Although it is a weird thing to do, both GUI and
latex output can deal with it.
This fixes a crash in examples/fa/splash.lyx when selecting text
representing menu entries. This happens because menu names are in LTR
English, while the inset itself is in RTL.
The problem is that the current code relies on the fact that
1. getColumnNearX and checkInsetHit share the same idea about cursor
position.
2. pos and pos + 1 are in general consecutive on screen.
It seems that 1. is wrong here (for reasons I did not try to
understand); the second assumption is definitely false with
bi-directional text. This makes editXY very fragile.
The new code should be more robust in this respect. The logic is:
* if checkInsetHit finds an inset, use its position,
* otherwise, ask getColumnNearX for the cursor position.
Fixes: #9142
When deciding whether a paragraph should be indented or not, LyX
only takes into account default layouts. This is wrong, because
an environment could be nested into another one and thus a following
paragraph would not be "default". With this patch all paragraphs
after an environment are correctly indented, independently of
whether their layouts are "default" or not.
The latex output (which was modeled following the previous wrong
assumption) is also correspondingly adapted.
If a new paragraph is created just before a nested environment,
the indentation of the nested environment is not computed
correctly because the parindent of the previous layout would
also be erroneously taken into account. This would cause the
nested environment to move back and forth when something is
added to the new paragraph.
LyX fails to indent on screen a standard paragraph when it is
nested into an environment. The fix is a one-liner but the diff
is larger because it also fixes a previous wrong indentantion
in the source ;)
If a layout has NextNoIndent set to true, the following paragraph
is not indented on screen. LyX checks the previous layout for that
style parameter to decide whether to indent or not. Of course,
what matters is the latex output and the on-screen representation
should match this output. Now, when a layout has NextNoIndent==true,
the latex output is correctly not indented, while the on-screen
representation may fail to match this output. This can occur when,
for example, a standard paragraph is nested in the previous layout,
because LyX would check the property of the nested layout instead
of the container layout. Thus, LyX should check the property of a
previous layout at the same depth for correctly deciding whether
a paragraph has to be indented or not.
See also http://www.lyx.org/trac/ticket/9055#comment:12 for an
example document where the previous scenario actually occurs.
The algorithm used for breaking a paragraph in LaTeX export is changed
for avoiding spurious blank lines causing too much vertical space.
This change is tied to the introduction of a new inset (with two
different specializations) helping in either outputing LaTeX paragraph
breaks or separating environments in LyX. Both of the above goals were
previously achieved by the ---Separator--- layout and can now be
accomplished by the new inset in a more natural way. As an example,
after leaving an environment by hitting the Return key for two times,
a third return automatically inserts a parbreak inset, which is
equivalent to the old separator layout, i.e., it also introduces a
blank line in the output. If this blank line is not wanted, the
parbreak separator can be changed to a plain separator by a right
click of the mouse. Of course, an environment can still be separated
by the following one by using the Alt+P+Return shortcut (or the
corresponding menu key), but now the plain separator inset is used
instead of the old separator layout, such that no blank line occurs in
the LaTeX output.
Old documents are converted such that the LaTeX output remains unchanged.
As a result of this conversion, the old separator layout is replaced by
the new parbreak inset, which may also appear in places where the old
algorithm was introducing blank lines while the new one is not.
Note that not all blank lines were actually affecting the LaTeX output,
because a blank line is simply ignored by the TeX engine when it occurs
in the so called "vertical mode" (e.g., after an alignment environment).
The old ---Separator--- layout is now gone and old layout files using it
are also automatically converted.
Round trip conversions between old and new format should leave a document
unchanged. This means that the new behavior about paragraph breaking is
not "carried back" to the old format. Indeed, this would need introducing
special LaTeX commands in ERT that would accumulate in roundtrip
conversions, horribly cluttering the document. So, when converting a
modified document to old formats, the LaTeX output may slightly differ in
vertical spacing if the document is processed by an old version of LyX.
In other words, forward compatibility is guaranteed, but not backwards.
TextMetrics::getColumnNearX (x -> pos translation) has special code to
ignore spaces at the beginning of a row, but neither the display code
nor TextMetrics::cursorX (pos->x translation) follow this logic. One
might argue that spaces should actually be ignored (like LaTeX does),
but this leads to UI issues and is probably too difficult to
implement.
An iterator is typicall incremented passed the valid data into the 'end'
state. However, if this means that other functions are called with invalid
parameter, we should fix this.
This explains why fontSpan was called with pos==size() while this was not
expected to happen.

As long as leftMargin() is not correctly implemented for
MARGIN_RIGHT_ADDRESS_BOX, we should also not do this here. Otherwise, long
rows will be painted off the screen and will not be editable.
If we are in rtl text, we *need* to check whether the first character is a

computed on the last row.
This bug was introduced in [0a137e31/lyxgit] to fix the computation for

DispatchResult to store a flag that tells us whether we need a buffer
update or not.
So: If you find a missing one, go to an appropriate place in the
dispatch and call cur.forceBufferUpdate() or, if you don't have a cursor
but do have a DispatchResult, call dr.forceBufferUpdate().
There is one remaining call I could not move, in
TextMetrics::redoParagraph. But this looks like an emergency call when
the macro context has not been set. There are also a couple calls that
are connected with buffer creation that I commented out, since the same
call is done again almost immediately. But I'm not positive about those.
Now the nice thing would be to do the same for updateMacros().

1. When a listing is inserted in a bit of text, the line above the listing is not drawn over the full width like it is done for lines above other insets. This is because InsetListing has a AlignLeft alignment. Now, if you start selecting downwards with the mouse in this empty area, strange selection drawings appear (see attachment).
This is caused by the fact that starting your selection at such a place, causes beg.boundary() to be true in TextMetrics::drawRowSelection(..). This is correct, but this value is true for _all_ selected lines. Now, the selection acts as if it is RTL text. Therefore, just like for end.boundary, this value needs to be reset for every line.
2. Starting your selection in an end margin often causes the selection in this end margin to be painted later. This is because when starting your selection in an end margin, you may have set a (possible empty) selection before really selecting the end margin. The problem is that the checksum (computed later) is the same for this empty selection and for the end margin selection. Therfore, we need a call to cur.setSelection() before evaluating cur.selection().
3. In the following two lines, it is assumed that there is only an end margin to be painted if the selection extends to the next paragraph. This is not true for the above described case of an AlignLeft Inset. Then, the margin has also be drawn within a paragraph
4. The end and begin margins are only painted when the selection extends into the following or previous paragraph. This difference is not resembled in the checksum if you first select a row completely and then procede to the next or previous paragraph as the selection remains at the end of a row. This also holds for the AlignLeft case. Therefore I added a term to the checksum to monitor whether the end and begin margins need to be drawn.

The need for a LayoutPtr arises from the fact that (a) we do not want to give our clients a Layout &, since we do not want them to be able to change our Layout; but (b) we also need to be able to change which layout is ours. So we cannot store a Layout const &. Or so it seems to the compiler.

from the one posted to the list.
The basic idea has two parts. First, we hard code an "empty layout"
(called PlainLayout, for want of a better name) in TextClass and read it
before doing anything else. It can therefore be customized by classes,
if they want---say, to make it left-aligned. Second, InsetText's are
divided into three types: (i) normal ones, that use the "default" layout
defined by the text class; (ii) highly restrictive ones, such as ERT and
(not quite an inset) table cells, which demand the empty layout; (iii)
middling ones, which default to an empty layout and use the empty layout
in place of the default. (This is so we don't get the same problem we
had with ERT in e.g. footnotes.) The type of inset is signaled by new
methods InsetText::forceEmptyLayout() and InsetText::useEmptyLayout().
(The latter might better be called: useEmptyLayoutInsteadOfDefault(),
but that's silly.) The old InsetText::forceDefaultParagraphs() has been
split into these, plus a new method InsetText::allowParagraphCustomization().
A lot of the changes just adapt to this change.
The other big change is in GuiToolbar: We want to show LyXDefault and
the "default" layout only when they're active.
There are a handful of places where I'm not entirely sure whether we
should be using forceEmptyLayout or !allowParagraphCustomization() or
both. The InsetCaption is one of these. These places, and some others,
are marked with FIXMEs, so I'd appreciate it if people would search
through the patch and let me know whether these need changing. If they
don't, the FIXMEs can be deleted.

paragraph relayout happens (e.g. when inserting a InsetBranch, the
InsetText inside was not processed by any updateLabels call), and
hence the macrocontext is not always set. This should not happen often
in fact. So we update the labels in that case explicitely when we see
an empty macrocontext.
