e30f3d76d2 Bulk cleanup/fix incorrect annotation at the end of namespaces.
This commit does a bulk fix of incorrect annotations (comments) at the
end of namespaces.

The commit was generated by initially running clang-format, and then
from the diff of the result extracting the hunks corresponding to
fixes of namespace comments. The changes being applied and all the
results have been manually reviewed. The source code successfully
builds on macOS.

Further details on the steps below, in case they're of interest to
someone else in the future.

1. Checkout a fresh and up to date version of src/

    git pull && git checkout -- src && git status src

2. Ensure there's a suitable .clang-format in place, i.e. with options
   to fix the comment at the end of namespaces, including:

    FixNamespaceComments:                           true
    SpacesBeforeTrailingComments:                   1

and that clang-format is >= 5.0.0, by doing e.g.:

    clang-format -dump-config | grep Comments:
    clang-format --version

3. Apply clang-format to the source:

    clang-format -i $(find src -name "*.cpp" -or -name "*.h")

4. Create and filter out hunks related to fixing the namespace

    git diff -U0 src > tmp.patch
    grepdiff '^} // namespace' --output-matching=hunk tmp.patch  > fix_namespace.patch

5. Filter out hunks corresponding to simple fixes into to a separate patch:

    pcregrep -M -e '^diff[^\n]+\nindex[^\n]+\n--- [^\n]+\n\+\+\+ [^\n]+\n'  \
        -e '^@@ -[0-9]+ \+[0-9]+ @@[^\n]*\n-\}[^\n]*\n\+\}[^\n]*\n'         \
        fix_namespace.patch > fix_namespace_simple.patch

6. Manually review the simple patch and then apply it, after first
   restoring the source.

    git checkout -- src
    patch -p1 < fix_namespace_simple.path

7. Manually review the (simple) changes and then stage the changes

    git diff src
    git add src

8. Again apply clang-format and filter out hunks related to any
   remaining fixes to the namespace, this time filter with more
   context. There will be fewer hunks as all the simple cases have
   already been handled:

    clang-format -i $(find src -name "*.cpp" -or -name "*.h")
    git diff src > tmp.patch
    grepdiff '^} // namespace' --output-matching=hunk tmp.patch  > fix_namespace2.patch

9. Manually review/edit the resulting patch file to remove hunks for files
   which need to be dealt with manually, noting the file names and
   line numbers. Then restore files to as before applying clang-format
   and apply the patch:

    git checkout src
    patch -p1 < fix_namespace2.patch

10. Manually fix the files noted in the previous step. Stage files,
    review changes and commit.

2a5bb7ab67 Fix bug #10685
Make sure to properly nest \begin{lang} and \end{lang} tags even
when no language package is selected. In this case, LyX assumes
that babel is being used, so the language names might be wrong
if the user arranged for using polyglossia in the preamble.
Nevertheless, we assure that the produced output is syntactically
correct, so that by adding proper preamble code a correct output
is still possible.

72a488d7e6 Fix output of en- and em-dashes with TeX fonts
This commit fixes the regression introduced in 2.2 about the
output of en- and em-dashes. In 2.2 en- and em-dashes are output as
the \textendash and \textemdash macros when using TeX fonts, causing
changed output in old documents and also bugs (for example, #10490).

Now documents produced with older versions work again as intended,
while documents produced with 2.2 can be made to produce the exact
same output by simply checking "Don't use ligatures for en-and
em-dashes" in Document->Settings->Fonts.

When exporting documents using TeX fonts to earlier versions, in order
to avoid changed output, a zero-width space character is inserted after
each en/em-dash if dash ligatures are allowed. These characters are
removed when reloading  documents with 2.3, so that they don't accumulate.

dea5ba16de Correctly track ulem commands with change tracking
LyX assumes that everything in \lyxdeleted is struck out by ulem
and increases the corresponding counter. However, deleted display
math material is struck out using tikz. As we also take into
account the deletion of underlined display math (in order to
properly position such material vertically), we have to take
care that the count is correct.

8d5899aaf3 Fortify math insets against ulem commands
It should be now possible underlining or striking out any kind
of math inset containing any math construct indigestible to ulem.
While this was already possible for inline math insets, they could
have break if an aligned environment was used, for example.
This is now possible also for diplay math. Even if this can be
nonsensical and not visually perfect, at least no latex errors
should be generated if one tries to.

129459a71b Take into account font changes when striking out display math formulas
Font changes are brought inside the \lyxdeleted macro, just before
outputting the latex code for the math inset. The inset writes a
signature before itself and this is checked by \lyxsout for recognizing
a display math. So, the font changes confuse \lyxsout, which also
swallows the first macro at the very start of \lyxdeleted. The result
is that the font changing command is not seen by latex and \sout is also
used to further strike out the formula already striked out by tikz.
This commit makes sure that the expected signature actually appears
just after the opening brace of \lyxdeleted. It also accounts for a
paragraph break occurring just before the math inset, in order to not
introduce too much vertical space, which is noticeable when using
larger font sizes.

261e7ae9ce Strike out (in the output) deleted display math with track-changes
Showing deleted display math by enabling "Show Changes in Output" was
only possible with dvi (through dvipost). Although LyX strikes out
such formulas on screen, it was impossible obtaining an output
directly using pdflatex (or other engines producing pdf) because
ulem cannot cope with display math material and gives errors.
The solution is to strike out by ourselves such deleted formulas.
I took into account several options. One of them would produce
an output similar to dvipost (which strikes out each element), but
would have required much more changes in the output routines.
Eventually, I opted for using tikz, which gives a more clean
output (as it requires to simply adding a preamble and a postamble
to the latex code of any displayed math, instead of a mark up
tailored to each particular math construct). The look of the pdf
output is similar to the way LyX strikes out the equations on screen.

1f6c451ee3 TexRow for InPreamble
This enables error reporting for the preamble, provided the preamble is written
using the new InPreamble layouts.

In the future, I find it preferable to deprecate the usual preamble in favour of
InPreamble layouts rather than implementing error reporting for the usual
preamble. This requires some improvements to code editing in the buffer view
first (line breaking behaviour, syntax highlighting).

f3256ee2cd texstring and otexstringstream
texstring is a pair of a docstring and a corresponding TexRow. The row count in
the TexRow has to match the number of lines in the docstring.

otexstringstream is an output string stream that can be used to create
texstrings (i.e. it's an odocstringstream that records the TexRow information
and let us extract a texstring from it).

texstrings can be passed around and output to otexstream and otexrowstream,
which produces an accurate TexRow information by concatenating TexRows.

31e25c8ec6 Fix problem with branch handling. The problem was that we were not
dealing properly with the paragraph separator tag.

We really need to use that tag as a kind of general marker for which
tags we're responsible for in a given paragraph and which tags we are
not. So the changes to InsetText.cpp use the tag as that kind of marker.

Note that, as of this commit, the User Guide again exports without any
kind of error. I haven't yet checked the other manuals.

This fixes bug #8022.

This was a regression of 8aa37c43. I did not take into account that end_pos
could be -1, so the code that checked whether a pair of braces needs to be
inserted between two hyphens did not work for that case. Now we check for
the length of text_, which should be done anyway, and only take end_pos into
account when it is not -1.

ba7e2113f3 Fix some display bugs related to end of paragraph markers
There are two regressions that are fixed here:

 * empty rows at the end of a paragraph (think after newline at end of
   paragraph or empty line in Verbatim) do not have an end-of-par
   marker. This is fixed by removing the early return in breakRow and
   letting the whole function be executed. This requires to relax an
   assertion in Paragraph::fontSpan. It makes sense here to query
   position at the end of the paragraph.

 * a newline at the end of a paragraph will be followed by and
   end-of-par marker. This is fixed by skipping the end-of-par marker
   when a new row has been requested.

0eb9477be7 Fix 480937a103708a651/lyxgit, second attempt.
Prevent encoding changes whenever the TeX engine is XeTeX or LuaTeX,
as XeTeX/LuaTeX use only one encoding per document:

* with useNonTeXFonts: "utf8plain",
* with XeTeX and TeX fonts: "ascii" (inputenc fails),
* with LuaTeX and TeX fonts: only one encoding accepted by luainputenc.

+1 no needless encoding switches
+1 runparams.encoding matches the correct encoding at any time
+1 less complicated code.

-1 there may still be problems with CJK (possibly impossible to
   solve for Xe/LuaTeX with TeX fonts).

For LuaTeX & TeX fonts, the complete document uses the encoding
of the global document language.

See also #9740.

9894e0be23 Fix 480937a103708a651/lyxgit. See also #9740.
Actually, the changed tests were used to prevent overwriting the encoding
changed in Buffer::writeLaTeX with a language-default encoding.
This is still required for XeTeX with TeX-fonts unless a proper solution is found.

Documents with more than one encoding and TeX-fonts fail with LuaTeX,
as "luainputenc" can only handle one encoding.

480937a103 Reset encoding after insets and environments also for LuaTeX with TeX fonts.
With inputenc == "auto" or "default", the encoding changes with
the language and must be reset after an eventual language switch in insets
or environments (see #6216).

However, whether we need to do this does not depend on 8-bit TeX vs. LuaTeX
but on the possible use of more than one encoding for the document.
With "nonTeXFonts", the encoding is utf8,
LuaTeX with TeX fonts requires encoding handling similar to 8-bit TeX.

(Additionally, the value of "params.inputenc" could be tested: if it is
not "auto" or "default", we have just one common encoding and could skip
the reset as well.) Not sure how much time this saves, though.

65d61e7a27 Add math cell positions to TexRow
This is preliminary work for extending the cursor<->row tracking to math.

TexRow used to associate, to each row, a location id/pos where id determines a
paragraph and pos the position in the paragraph.

TexRow now associates to each row a list of entries, text or math. A math is a
pair uid/idx where uid will determine a math inset and idx is the number of the
cell.

The analogy id/pos<->inset/idx works better than the analogy id/pos<->idx/pos,
because what matters for the TexRow algorithm(TM) is the behaviour in terms of
line breaks.

This only improves the source view and the forward search, not the error report
and the reverse search (though this could be easily added now).

bb344452c8 Consistency of ellipses across the UI
Use the function support:truncateWithEllipsis() to shorten a docstring with

truncation and is much nicer on the screen.

This includes the bugs #9575 and #9572 regarding broken text elision in the
outliner.

Known issues (non-regressions):

* TocBackend::updateItem() should be rewritten to update all TOCs. (#8386)

* "..." should be replaced with … everywhere else on the interface (including
  translation strings).

* We should prefer to rely on QFontMetrics::elidedText() to truncate strings
  with an ellipsis whenever possible, or an equivalent for the buffer view
  dependent on the font metrics. See the warning in src/support/lstrings.h.

4796e6b337 Avoid breaking kerning with continuous spell checking
There is a mismatch between the way text is tokenized in Row objects
and the way it is shown on screen. When metrics are computed,
continuous spell checking has not been done yet. Yet, the row painter
explicitly breaks words at spell status boundaries. This creates
problem with a text like "PMP," (see bug #9649), where there is a
negative kerning before the comma.

This is solved by not taking in account spell status when drawing
text, and drawing spell underlines separately.

* replace Paragraph::isSameSpellRange with new method getSpellRange.

* merge RowPainter::paintChars into RowPainter::paintFromPos

* move the actual text painting code into the new paintTextAndSel.

* merge some code from paintFromPos to paintMisspelledMark

* in paintMisspelledMark, scan the string which needs to be annotated
  and add dashed line below text marked as misspelled.

special insets for these words, and standard text is left alone.

8aa37c43a1 Fix plaintext output of dashes (bug #3647)
Previously, consecutive dashes in .lyx files were combined to endash and emdash
in some cases, and in other cases they were output as is. This made the code
complicated, and resulted in inconsitencies ((bug #3647).
Now, a dash in a .lyx file is always a dash in the output, for all flavours.
The special handling is moved to the input side, so that you still get an
endash if you type two hyphens. If needed, this can be changed or made
customizable without the need to update the file format again. Many thanks
for the fruitful mailing list dicsussion, which contributed significantly to
the final version.

e4ec11e8a1 Output -- and --- in XHTML like in LaTeX
For exports based on LaTeX, consecutive hyphens are only converted to endash
and emdash if the current font family is not typewriter, and if none of the
parent insets is an IPA inset. Now this is done for XHTML export as well.

0bf8b8a1d2 Load footmisc.sty instead of using outdated code
This is a patch I originally sent to lyx-devel in 2012 with subject
'Load footmisc.sty instead of using copied code from obsolete stblftnt.sty'.
It now takes all comments into account: It works also if the user loads the
package herself, it can be disabled by providing the footmisc feature in a
layout, and it does not use the ugly \AtBeginDocument{}.

41740ea915 Merge remote-tracking branch 'features/str-metrics'
This branch implements string-wise metrics computation. The goal is to
have both good metrics computation (and font with proper kerning and
ligatures) and better performance than what we have with
force_paint_single_char. Moreover there has been some code
factorization in TextMetrics, where the same row-breaking algorithm
was basically implemented 3 times.

Globally, the new code is a bit shorter than the existing one, and it
is much cleaner.  There is still a lot of potential for code removal,
especially in the RowPainter, which should be rewritten to use the new
Row information.

The bugs fixed and caused by this branch are tracked at ticket #9003:
http://www.lyx.org/trac/ticket/9003

What is done:

* Make TextMetrics methods operate on Row objects: breakRow and
  setRowHeight instead of rowBreakPoint and rowHeight.

* Change breakRow operation to operate at strings level to compute
  metrics The list of elements is stored in the row object in visual
  ordering, not logical. This will eventually allow to get rid of the
  Bidi class.

* rename getColumnNearX to getPosNearX (and change code accordingly).
  It does not make sense to return a position relative to the start of
  row, since nobody needs this.

* Re-implement cursorX and getPosNearX using row elements.

* Get rid of lyxrc.force_paint_single_char. This was a workaround that
  is not necessary anymore.

* Implement proper string metrics computation (with cache). Remove
  useless workarounds which disable kerning and ligatures.

* Draw also RtL text string-wise. This speeds-up drawing.

* Do not cut strings at selection boundary in RowPainter. This avoids
  ligature/kerning breaking in latin text, and bad rendering problems
  in Arabic.

* Remove homebrew Arabic and Hebrew support from Encoding.cpp. We now
  rely on Qt to do handle complex scripts.

* Get rid of LyXRC::rtl_support, which does not have a real use case.

* Fix display of [] and {} delimiters in Arabic scripts.

45eb314a86 Get rid of rtl_support preference
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!

d6337a2488 Remove obsolete code to handle Hebrew and Arabic characters
This is handled by Qt now.

Note that a small optimization (do not draw text that is to the left
of WorkArea) is removed because it cannot be guaranteed to be exact
anymore. It was probably not very useful anyway, and would become
useless once the RowPainter is rewritten to use Row information.

2896fe1bd0 Work around MSVC warning
The statement
	if (pos < from + lyxrc.completion_minlength)
triggers a signed vs. unsigned warning. I don't know why this happens, it
could be a MSVC bug, or related to LLP64 (windows) vs. LP64 (unix)
programming model, or the C++ standard might be ambigous in the section
defining the "usual arithmetic conversions". However, using a temporary
variable is safe and works on all compilers.

ee7c4db72a Do not forget last word of paragraph in completion
With the old code, the last word of a paragraph would not be added in
the completion list. The key difference is to pass `from' instead of `pos'
to FontList::fontiterator.

Slight cleanup of the code.

c668ebf611 Fix bugs #8546 and #9055, and introduce new separator inset.
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.

f8da042312 Do not store Languages objects in completion words lists
In the current code each paragraph contains a map<Language,
WordList*>, which means that it contains a full copy of the language
object. Since these objects contain translation tables nowadays, this
is a very bad idea.

This patch simply replaces the Language key by a string.

consumption decreases from 36.27MB to 31.50MB.

795535e44f Do not try to track_change an auto-deleted bibitem
We are not capable of handling two bibitems within one biblio paragraph.
That's why we have functions like Paragraph::brokenBiblio() and
Paragraph::fixBiblio(). So, if we fix the biblio by deleting the second
bibitem, we should not keep it as deleted.

This code caused a crash because the inset was released, but still kept as
deleted.

2d8941eec3 Revert "Fix assertion for InsetInfos of icon types"
Using "Font no_font" in case no font was supplied was wrong. Instantiating a font object without specifying the language lead to a font object having the default_language that is hardcoded to "english". See Language::read().

This caused that there were spurious language changes in the LaTeX output
and made some document uncompilable.

This reverts commit 3619954590.
