Now when double clicking on a boundary of a word, the
word is selected. This also causes single-letter words
to now be selected (fixes#9159).
Backported from bcbc162.
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.
The lyx2lyx conversion for format 352 was incomplete: It should have been
added the \use_indices setting, but it relied on the fact that the default in
LyX for missing \use_indices is the same as the old format without that
setting used. However, the default might change in the future, and later
lyx2lyx conversions rely on that setting as well.
Without this, you get crashes in a few second when you set the autosave
interval to one second and edit quickly (typing new words etc). The reason
is that the cloned buffer wants to insert words into the word list and
remove them again, but it lives in a different thread.
This avoids dataloss in case we are unable to write the new one after
all.
A more sophisticated approach, due to Georg, is in master, but it needs
more testing that it will be able to get before the release of 2.1.1.
That should be committed to 2.1.x when it is ready and this patch backed
out again.
On startup, the default locale is "C", meaning that all system
functions assume an ascii codeset. The environment's locale
settings should be selected by calling setlocale(LC_ALL,"").
This is done by Qt during the QCoreApplication initialization
but this inizialization is never performed for batch processing
and, as a result, LyX is not able to process files whose names
contain non-ascii characters. This is not an issue on Windows,
where the file names are always stored as UTF-16, so the call is
only performed for unix-like platforms (this also includes cygwin,
due to its own filenames management that allows using characters
which are forbidden to native programs).
The problem is the use of cursor movement methods to update cursor.
Cursor::forwardPos() steps into insets, which is not always what we
want. The problem here is that there is a math inset just after the
accepted change, and that the cursor steps into it for some reason.
This code is a nightmare anyway.
Fixes: bug #9145
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
temporary name, then move it to its real location if we succeed.
This prevents our over-writing the existing file with a corrupt
one.

trim_eol() assumes that a line always ends either with \n, \r, or \r\n.
This assumption is always valid except for the last line of a document, since it
may miss the trailing newline. LyX does not create such documents, bu they may
result from automatic creation tools, and LyX can read them, so lyx2lyx should
be able to read them as well.

The real problem is the encoding of latex_language: It is hardcoded to latin1,
but InsetListig uses the currently active encoding. Therefore, we cannot tell
whether any given character wil be encodable or not, and we should not prevent
non-ACII characters.
In the future, we need to make the encoding of latex_language dynamic, so that
it always represents the currently active encoding. Then, we could do the
correct check both for listings and ERT. For now, I simply disabled the
encoding check for listings, which also means that bug 9012 might occur in
other cases for listings, but this is less important than bug 9102.
LyX assumes that a standard paragraph following a layout with
NextNoIndent==false has to be indented on screen, so output the
necessary blank line to make it so also in the output.
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.

example document where the previous scenario actually occurs.

lyx2lyx sets all new math packages to off when converting from old formats.
This is correct if any command which would cause an automatic package loading
exists in the document. However, it is wrong if no command exists: This leads
to problems if later a command is added (bug #9069), which is especially
annoying for templates.
The fix consists of two parts:
1) convert_use_package() considers now the used commands like
revert_use_package(), and uses them to decide whether to set the package to
auto or off.
2) convert_undertilde() and revert_undertilde() use a slightly adjusted copy of
convert_use_package() and revert_use_package(), so that the bug is also
fixed for undertilde. We cannot use the latter functions directly, because
of "\usepackage undertilde" vs. "\use_undertilde".
When doing the lyx2lyx round trip of the 2.0.8 user guide from format
413 -> 474 -> 413 you get an invalid document, because the math packages
mhchem and undertilde are incorrectly converted.
It turned out that the old reversion code did only work for particular
package oderings. The new one works for abitrary sorted packages.
When doing the lyx2lyx round trip of the 2.0.8 user guide from format
413 -> 474 -> 413 you do not get a zero diff. The most important problem is
caused by the conversion of the argument insets to the old syntax: This
conversion adds an additional empty line (harmless), and it destroys the
document structure if the first inset in e.g. a subsection is not an argument
inset, but e.g. an index or label inset.
The fix is quite easy: Ensure that the paragraph begin is set to the first
argument inset.
revert_justification() issues a warning if the \justification parameter does
not exist, and LyX itself always writes it unconditionally as well, so add it
also in lyx2lyx when converting old documents.
Currently this does not have any user visible effect, but it decouples the
default value of BufferParams::justification from the conversion of old
documents: Now it is possible to set the default to false in LyX, and old
documents will still be converted correctly.
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.
When loading the Userguide on linux/x86_64, the total memory
consumption decreases from 36.27MB to 31.50MB.
