This is needed since src/support calls lots of qt code, and some parts of it
(e.g. QFileInfo) require a running event loop. This fixes bug #4917 which is
a symptom of the problem.
The fix is to create a QCoreApplication for tex2lyx, lyxclient and LyX running
without GUI. In the future this could be extended, i.e. to split up the
frontend Application class in a GUI and a console class, and having the
console class use LyXConsoleApp in the same way as Application now uses
GuiApplication. If that is done, one could also think of moving
support/ConsoleApplication to frontend/console/ConsoleApplication.
These are now in version.cpp. The build machinery should therefore make sure
that version.cpp is recompiled at every compilation.
These variables are now referred to by the other places that made use of __DATE__ and __TIME__.
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.
Get the default language by a mix of QLocale and LyXRC::gui_language
Known limitations:
* encoding is supposed to be UTF-8 (the charset parameter is checked);
* context is not handled (implemented differently in LyX);
* plural forms not implemented (not used for now in LyX);.
* tThe byte endianness of the machine on which the .mo file have been
built is expected to be the same as the one of the machine where this
code is run.

There are several places I was not sure what to do. These are marked
by comments beginning "LASSERT:" so they can be found easily. At the
moment, they are at:
Author.cpp:105: // LASSERT: What should we do here?
Author.cpp:121: // LASSERT: What should we do here?
Buffer.cpp:4525: // LASSERT: Is it safe to continue here, or should we just return?

Cursor.cpp:403: // LASSERT: Is it safe to continue here, or should we return?

CursorSlice.cpp:83: // LASSERT: This should only ever be called from an InsetMath.

This is a second attempt to fix the problem described in
6df4a7bb (2c2c1767 reverted the first attempt).
The solution here is more general: if we get to a certain point
in the code and there is no filename, an error is given.
The following command now gives an error:
lyx -e pdf2
And the following command continues to not give an error:
lyx myfile.lyx -e pdf
Before, the following commands correctly exited with code 1, but now
a reason for exiting is also given:
lyx -e pdf2 doesNotExist
lyx doesNotExist -e pdf2
This reverts commit 6df4a7bb40.
As Vincent points out, this commit is not correct. For one reason,
it would incorrectly exit with error for the following syntax:
lyx myfile.lyx -e pdf
I will look for a correct solution to the problem specified in the
message of the reverted commit.
Before, 'lyx -e pdf2' would give no error and would exit with 0. A use
case is if a user has in a bash script the following command:
lyx -e pdf2 "${mylxyfile}" || exit 1
where 'lyx' is mispelled as 'lxy' and thus yields an empty
string. If LyX does not exit with an error, the script continues where
the user probably intends for it to stop.
The LaTeX font information are now centralized and outsourced. This removes a lot of hardcoding and duplication and makes it easier to support new LaTeX fonts.
The goal here is to get rid of the old code that modified variables
LANGUAGE and LC_ALL, therefore creating the problems mentionned
in the ticket.
In the new system, there is no explicit "GUI" message handler, that
needs to be reset at each language change. Instead, getGuiMessages
calls getMessages with the correct parameter. This allows to simplify
greatly the code and to remove a lot of old cruft.
While cppcheck did not turn out any suspicious error messages, using
the "performance" flag highlighted several nitpicks in three categories
* do not use it++ for iterators, ++it is better
* do not use size() to test for emptyness, empty() is here
* do not use "const T" as a function parameter, "const & T" is better
I doubt that any of these is a real performance problem, but the code is cleaner anyway.
The PreviewLoader is created directly by Buffer on demand. The PreviewLoader cache was complex and unneeded because there is one and only one PreviewLoader per Buffer.
