Useful to cache copies of objects, including shared_ptrs. No risks of dangling
pointer, and avoid naked pointers in the source.
Fix memory leak when compiling with Qt5.
RefChanger temporarily assigns a value to a non-const reference of any
kind. RefChanger provides a flexible and uniform generalisation of the various
scope guards previously derived from the old Changer class in MetricsInfo.h.
As before, a temporary assignment lasts as long as the Changer object lives. But
the new Changer is movable. In particular, contorsions are no longer needed to
change a private field. Special code can be moved into the appropriate classes,
and it is no longer necessary to create a new class for each specific use.
Syntax change:
FontSetChanger dummy(mi.base, value);
-> Changer dummy = mi.base.changeFontSet(value);
New function for generating arbitrary Changers:
Changer dummy = make_change(ref, val, condition);
Bugfix:
* Fix the display of \displaystyle{\substack{\frac{xyz}{}}} (missing style
change).
The included iconv should not be used on Linux or OS X, but (depending on
local configuration) it might be needed for crosscompiling a mingw target
from Linux. Now the user can choose whether to use the included iconv or not.
cmake does already support that.
eilseq.m4 was taken from the original libiconv 1.14 package.
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.
The interface is now 100% unit tested, and the typedefs depend on the new
STD_STRING_USES_COW configuration variable. The only missing bit is to detect
clang and disable STD_STRING_USES_COW for clang.
The option --enable-qt5 allows configuring for Qt5. The default is Qt4.
Nothing special is done with respect to Qt4, apart from pulling in the
correct libraries. Indeed, other than the core and gui libraries, now
also the concurrent and widgets libraries are needed.
FileName::tempName() is not thread safe, since the QTemporaryFile object is
immediately deleted after creating it. Therefore, another thread could create
the same temporary file in the time span before the user of FileName::tempName()
recreates it. This is not as theoretical as it may look: I observed that
repeated creation and deletion of QTemporaryFile objects always use the same
name.
This problem is solved by the new class TempFile which should be used like
QTemporaryFile itself.
The use of this profiler is trivial:
* #include <support/pmprof.h>
* in the block one wants to profile, add
PROFILE_THIS_BLOCK(some_identifier)
* At the end of the execution, statistics will be sent to standard error.
A dummy getGuiMessages function was missing. Instead of adding it everywhere, a new file is created that contains all the dummy functions needed by the tests.
In order to interact with native osx applications, AppleScript support is a plus.
Here is a patch that makes LyX respond to a simple command (run) and that allows to communicate with LyX as with the LyX client.
Example of use:
tell application "LyX" to run "server-get-filename" with argument ""'
returns
message:/Users/bpiwowar/newfile1.lyx, code:0
with a message and the error code
