- present appropriate alert message in case of missing Python
- add the option to quit LyX immediately
- recheck for Python interpreter on reconfigure if it was missing
This restores the previous behavior of runCommand().
When the child process could not be properly terminated the
error "RunCommand: could not terminate child process" was being
issued. However, in fb7b7e52 there was a misinterpretation
between this condition and the exit status of the child and
these two different errors were mixed up. They are now
disentangled again.
Remove all trace of Qt4 support. The different elements have been
considered carefully before removal.
The only changes that need to be done concern Windows and macOS
compilation instruction and will need to be taken care of by the
respective maintainers before prerelease.
The file TODO.killqt4 lists what remains to be done.
We now allow the user to cancel the background process at any point
(via the red "x" in the status bar or Document > Cancel Export), so
we do not need to poll the user with the dialog.
The patch works by setting timeout to "-1" which is treated as a
special value to disable the poll.
Fix (by obviation) #12531 and #9953, which were about the dialog.
Qt4 code has been identidifed by
git grep -l 'QT_VERSION.*\(0x050000\|0x04\)' src
Uses of QT_VERSION_CHECK have been checked too.
been used to remember what places need further work.
Then remaining Qt4 references have been searched using
git grep -i qt4
git grep -i 'qt 4'
and relevant issues have been either fixed or noted in the new
TODO.killqt4 file.
In order to work around the Qt row breaking algorithm, which considers
multiple spaces as one at QTextLine break, we insert word_joiner unicode
characters beteween each pair of spaces.
The TextLayoutHelper class makes it easy to handle that.
Update Row::Element::rtrim() to only remove one space at row end.
Update support::countExpanders() to count all spaces, without special
handling for consecutive ones.
Fixes bug #10117.
When there is no module, the old code would invoke tex2lyx with option
-m
instead of
-m ""
and an error would ensue.
This is because the QProcess command line parser used in Systemcall is
broken and does not recognize empty parameters as such. The solution
is to rewrite our parsecmd() parser to generate a list of parameters.
This is post-2.4.0 work.
The workaround used here is:
- set the list of modules to "," when it should be empty. In effect,
this is a list of two empty modules.
- change tex2lyx to accept empty module names and ignore them; this is
good in terms of robustness anyway.
Additionally, when there is no receiving buffer, set the defaults as
the BufferParams defaults instead of empty (this is cleaner, but
should not make a difference in practice).
In the long term, we should switch to use the QStringList-based API of
QProcess in Systemcall (see QTBUG-80640).
**WARNING; only compilation has been ested; even that does not work**
The goal of this commit is to use the list-based API to
QProcess::start, to avoid annoying syntax issues (see issues with
pasting from LaTeX).
* Create a new latexEnvironment() in filetools.h that returns a
map<string, string> containing the variables and their values.
* Rewrite parsecmd() so that it returns a QStringList of tokenized parameters.
* Use this in startProcess. This is the part is is not finished yet.
Obviously, this will not be possible to get right for 2.4.0.
This quashes a new warning in clang++ 15, when std::move() (the
one-parameter version) is used as simply move(). There is a strong
recommendation from WG21 to avoid that.
Details here: https://reviews.llvm.org/D119670
It might be that we should not use that many move()s. I am not
competent to decide on that.
I also used this occasion to get rid of a spacial casing for C++11
that does not seem necessary after all.
In several range-based for loops, implicit copies are made. Remove
that when possible, and try to shut converity up otherwise.
Fixes issues found by coverity.
Introduce the new FileName method ensureExtension, which does the following:
* if the extension is already correct (in a case-insensitive way), do nothing.
* if it is not correct, add the extension to the file name.
This is different from changeExtension that will fail in a case where
the file contains dots, but not a real extension, like newfile2.1.
Use this new method in renameBuffer() and exportBufferAs().
Fixes bug #11008.
In FindAdv we use Qt to interpret regular expressions.
Regex uses for instance '\w', '\d' etc.
'\d' finds not just '0-9' but also e.g. '߂' (Nko Digit Two: U+07c2)
'\w' includes also such numbers.
ATM, only FindAdv uses this function.
With the debug-level 'find' there are now less output.
The original output can be received now with debig-level 'findverbose'
Also constructions like
LYXERR(Debug::FIND|Debug::FINDVERBOSE, "...");
are now possible.
It is not a good idea to contruct a QChar from a char_type that is
really 32bits.
Use lyx::isSpace, which already catters for this case.
Since this code does not depend on qt anymore, move it to
support::countExpanders.
Get rid of Row::countSeparators, which is not used anymore.
Fixes bug #12519.
This ensures that we use a consistent Python interpreter in LyX.
$${python} is replaced by the Python version found.
Users can apply this in preferences and use the same version defined by
LyX.
We could not figure out the root issue, or at least not to the point
where we felt changing this code considering we could not trigger
any bug from a user perspective.
For now, we just add a comment in the code.

This fixes two performance issues and improves the performance of
TextMetrics::redoParagraph by 15% in a workload that uses the cache a
lot. The difference will be much less when the cache is not used much.
1/ repetion of the hash code computation
The code
if (cache.contains(key))
result = cache[key]:
is not efficient, since qHash(key) has to be computed twice.
To fix this a new Cache::object_str() method is added, which allows
if (auto * obj = cache.object(key))
result = *obj;
2/ code of has code computation
Instead of using a verbose string that is complicated to build as
key, new key structs BreakAtKey and TextLayoutKey are introduced,
along with the relevant qHash() implementation.
I wanted to remove the test Qt >= 5.15, but now I see that it is
not possible because of QProcess::splitCommand.
Neverthless, the best would be to change parsecmd.
Add new funciton Debug::badValue, that returns the first bad value in a debug
setting string.
Use it to parse the -dbg comand line option and to control the
execution of the debug-level-set lfun.
Use range-based loops in a few places.
Patch from P. De Visschere
Citing:
I also must exclude the QMacPasteboardMimeGraphics class in
GuiApplication.cpp since QMacPasteboard is not available anymore with qt6.
and add an #include <QStandardPaths> in support/Package.cpp (I suppose
this will pose no problem for qt5 but have not checked it, it's only
needed with USE_MACOSX_PACKAGING)
