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.
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.
* 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
(unless it's already there, in which case it should move to the end of the next paragraph).
Change the preference setting name (mac_like_word_movement to mac_like_cursor_movement)
to better reflect its function.
Patch and description from Bennett Helm
The panels in GuiDocument and GuiPrefs are stored in a map. The keys are
the translated descriptions of these panels. Whenever someone changes the
gui language and reopens the Document Settings pane, LyX asserted because
it could not find the "Child Documents" pane.
If the WA is the last one showing a buffer, then the buffer may either be
closed or kept hidden, or the user is asked. The behaviour is controlled
by a new preference option.
For discussion, see http://comments.gmane.org/gmane.editors.lyx.devel/142638
The previous scheme of loading all possible translations and checking
whether the work is a bit too much "brute force" and causes problems
on Mac OS X (documents loaded with the wrong language).
Now there is an helper static method in Messages class that checks
whether a readable .mo file exist for the language. There should be an
API in gettext for doing that, but alas it is not possible.
As a consequence the method Language::translated() has been removed,
along with its cache.
- This preference was used for specifying the papersize to xdvi, dvipdfm,
dvips. However, I can't seem to see any effect on the result.
- The papersize should instead be defined in the document settings.
- The global papersize default was misused to also change the tex
output by specifying the papersize as if it was specified in the
document settings. This caused the same lyx document to be outputted
differently on different pcs.

Additionnal extensions are separated by commas (,) in lyxrc
preference files, while spaces are ignored, e.g. "jpg, jpeg".
Preference lyxrc file format incremented to 2.

Set a validator on QLineEdit widgets. The validator removes any
\n and \r characters, thus preventing users from copy-pasting
newline characters into these fields, and subsequently saving
them, inadvertantly, to the preference file.

Basically, patch adds routine that calcuates relative paths to parent
rather than child directories.

variable. This is done in the preferences, much like as the PATH prefix.
A single '.' in the paths will get replaced with the current document dir
and also non-absolute paths will be prefixed with that dir.
The default semantics of TEXINPUTS apply, such that, for example, if a
path is terminated with a double slash, all subdirectories will be also
searched by both the TeX engine and ancillary programs such as dvi
previewers or dvips. As an example, if the prefix is set to ".:figs", the
TEXINPUTS variable will be set as ".:<docdir>:<docdir>/figs:$ORIGTEXINPUTS",
where <docdir> is the document directory.
The initial '.' is necessary to address the actual current dir (this will
be the temp dir at preview time), while if TEXINPUTS was initially unset,
such that $ORIGTEXINPUTS is empty, a colon (or semicolon on Windows) will
end the path list. This is very important, because we don't want to replace
the system directories but to complement them and, in order to do that, an
empty element has to be present in the list. Indeed, according to the
TEXINPUTS semantics, an empty element means the standard search path.
This works whether TEXINPUTS is originally set or not, because if the
original TEXINPUTS starts with a colon (meaning that the standard search
path is wanted there) we will have an empty element at that point,
otherwise the final colon will simply serve as a path separator.
Of course, on Windows a ';' has to be used as a path separator. LyX will
take care of transforming the platform path list into one understandable
by the TeX engine. For example, this will be the case for a Cygwin version
of LyX using a native Windows TeX engine or viceversa. I tested all of
this and it works for me.

the size of icons may be wrong when switching between sets with different
normal icon size. One needs to save the preferences, restart LyX and choose
"Normal-sized icons" from the toolbar menu to have the real normal size.
A minor glitch is that the name of the icon sets is translatable, but
currently only the translation for "Default" works. The problem is that I
don't know how to ask gettext for an inverse translation when saving the
preferences. Another possibility would be hardcoding the order of the names
in the combo box (such that to not rely on their names), but that is ugly
and prone to errors if/when other sets are added.
