On Windows, start viewers in detached processes in order to avoid
a crash of the QProcess destructor when their thread terminates.
The opening of a console window is avoided by redirecting to the
null device all standard I/O channels.
The problem with the previous attempt was that, every time through
updateBuffer, we looked up the file location using kpsewhich, which
took too long on Windows. The new solution is to cache that info, and
to look it up only when we need it.
Previously, this info would have been re-read whenever we parsed the
bibfiles. So we re-read it now whenever the bibinfo cache is invalid,
which is less often, but should be good enough. We can add more such
re-reads if need be.

This allows to address data in the current lyx-system-directory.
The additional prefix is '~:s/'
The original prefix '~/' still addresses current users home directory.
This reuses code intended only for mac manus and generalizes it. The
list of strings to add to po files is found in
GuiTranslator::translate.
This is useful now that LyX relies on QDialogButtonBox class for its
dialogs. Indeed many languages are not covered natively by Qt.
It is possible to enable the "locace" debug channel to see what
strings are not covered and should be added to our own translation
tables.
In order to make things easier, a new method getIfFound() has been
added to the Messages class, which returns an empty string when no
translation has been found, as Qt's translate() does.
In such filesystems, including either Magic.h or magic.h does not
make any difference and the one or other file is included depending
on the search order. In this case, Magic.h was trying to include
itself instead of including magic.h.
This makes the code much easier to read and, additionally, allows to
parse the magic file with magic_load() only once per session.
As a result, getFormatFromFile is slightly faster.
This exception in the regex constructor is only theoretical (our regex
are hardcoded), but this is creating coverity noise.
Additionally, revert the following commits that are not needed anymore:
6b6fa94c: Catch exceptions to please coverity
c2ed75fd: Fixup 6b6fa94c: coverity says there are more possible exceptions.
This commit is better viewed with 'git show -b'.
This is needed for cases where the temp file has to be manually removed
at some point (e.g., if temp files are used as conversion target, and
the initial file only serves as a placeholder), since QTemporaryFile
objects cannot be manually removed at least on Windows (they are always
kept open internally even after close()). See
http://lists.qt-project.org/pipermail/interest/2013-August/008352.html
In order to avoid race conditions due to duplicate names (the issue why
the old method was removed), we record all used temp file names.
Fixes: #9139
A basic class like Length should not depend on something from
frontend.
This change allows to remove several dummy implementations of
theFontMetrics().
It is not good for a support function to depend of anything outside of
it, especially Application.
Here the boolean that indicates that export should be canceled is put
in Systemcall. This allows to remove all the dummy theApp() function
that have been added here and there for linking needs.
Spaces are, amazingly, allowed at the end of bibliography keys. So we
introduce a new parameter allowing getVectorFromString not to trim
whitespace, and then use it.
This commit does a bulk fix of incorrect annotations (comments) at the
end of namespaces.
The commit was generated by initially running clang-format, and then
from the diff of the result extracting the hunks corresponding to
fixes of namespace comments. The changes being applied and all the
results have been manually reviewed. The source code successfully
builds on macOS.
Further details on the steps below, in case they're of interest to
someone else in the future.
1. Checkout a fresh and up to date version of src/
git pull && git checkout -- src && git status src
2. Ensure there's a suitable .clang-format in place, i.e. with options
to fix the comment at the end of namespaces, including:
FixNamespaceComments: true
SpacesBeforeTrailingComments: 1
and that clang-format is >= 5.0.0, by doing e.g.:
clang-format -dump-config | grep Comments:
clang-format --version
3. Apply clang-format to the source:
clang-format -i $(find src -name "*.cpp" -or -name "*.h")
4. Create and filter out hunks related to fixing the namespace
git diff -U0 src > tmp.patch
grepdiff '^} // namespace' --output-matching=hunk tmp.patch > fix_namespace.patch
5. Filter out hunks corresponding to simple fixes into to a separate patch:
pcregrep -M -e '^diff[^\n]+\nindex[^\n]+\n--- [^\n]+\n\+\+\+ [^\n]+\n' \
-e '^@@ -[0-9]+ \+[0-9]+ @@[^\n]*\n-\}[^\n]*\n\+\}[^\n]*\n' \
fix_namespace.patch > fix_namespace_simple.patch
6. Manually review the simple patch and then apply it, after first
restoring the source.
git checkout -- src
patch -p1 < fix_namespace_simple.path
7. Manually review the (simple) changes and then stage the changes
git diff src
git add src
8. Again apply clang-format and filter out hunks related to any
remaining fixes to the namespace, this time filter with more
context. There will be fewer hunks as all the simple cases have
already been handled:
clang-format -i $(find src -name "*.cpp" -or -name "*.h")
git diff src > tmp.patch
grepdiff '^} // namespace' --output-matching=hunk tmp.patch > fix_namespace2.patch
9. Manually review/edit the resulting patch file to remove hunks for files
which need to be dealt with manually, noting the file names and
line numbers. Then restore files to as before applying clang-format
and apply the patch:
git checkout src
patch -p1 < fix_namespace2.patch
10. Manually fix the files noted in the previous step. Stage files,
review changes and commit.
Using a regular expression to find /src/ or \src\ in a string is overkill,
and since regexes can throw exceptions, it makes coverity nervous.
The new code is simpler anyway.
When the Buffer is notified to be externally modified, check that the
file contents have changed using the checksum.
Document the shortcoming of FileMonitorBlocker.
Fixes#10642.
Starting at 61b2bd5e, boost::bind was progressively replaced with
std::bind. They are not interchangeable though. boost::bind implements
the tracking of boost::signals{,2}::trackable objects. Now that
std::bind has completely replaced boost::bind, tracking never occurred.
This commit replaces boost::signals2::trackable with the new preferred
boost::signals2 methods: scoped_connections or slot::track_foreign. The
support::Trackable class introduced is less safe but easier for transitioning
old code.
Fixes the crash at #8261.
This reverts commit d568846e03.
Unfortunately the used alternative API LSCopyDefaultApplicationURLForContentType
is available with 10.10 and later only and cannot be used therefore. So there
is no alternative to deprecated calls ATM. LyX 2.3 should run on 10.7 at least.
Seemingly, when removing an argument from argv, and thus inserting
a null pointer to shorten the array, causes an assertion because
the null pointer is not a valid heap pointer (sic!)
Fixes bug #10440
There a some exceptions related to the fact that BOOST_ASSERT throws
an unhandled exception, which is fait enough. This is handled by
uploading a modeling file to coverity.
The second batch of issues are related to the use of lexical_cast in
convert.cpp. We use now a wrapper around boost::lexical_cast that does
not throw but return empty strings instead. I am not sure actually of
when lexical_cast could fail.
The added cmake-parameter is:
-DLYX_EXTERNAL_MYTHES=<value>
where <value> is one of
AUTO (Default) Search first on system for mythes (lib and include)
ON Use installed only (errors if not installed)
OFF Compile the provided source in 3rdparty
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.
For biblatex, we need the file name as it was entered in the inset
(abs path, rel path, only file name) in order to resolve it properly
for the export (as in the BibTeX inset intself).
Therefore, we now store a pair<docstring, FileName>.
A FileNamePairList has been added to FileNameList for this purpose.
Fixes: #8831
This introduces
* a new inset member isPartOfTextSequence() that returns
whether the inset produces something visible at the current position
in the text flow
* an isOpenPunctuation() test that returns whether a character is in the
'Punctuation, Open' unicode class. This is used instead of just checking
for two (Western, ASCII) opening brackets
It also fixes the isChar() and isLetter() value of InsetSpecialChar,
since some types have not been assigned correctly.
The QTextLayout handling is terribly slow on Qt 4.8.7, but some
caching has been added in Qt5 that makes it much faster. For some
reason, it is not that slow with Qt 4.8.1.
Caches are introduced for the three following methods
* width(doctring), controlled by CACHE_METRICS_WIDTH. This cache already
existed, but the code has been cleaned up
* getTextLayout, controlled by CACHE_METRICS_QTEXTLAYOUT (disabled by
default on Qt5, which does its own caching). This is used for pos2x
and x2pos and now for drawing of text too. The previous code used a
trivial caching scheme of the last used QTextLayout, but now they
are properly kept in a QCache. Moreover, the cacheEnabled() property
is enabled for these QTextLayout object (not sure what this does).
* breakAt, controlled by CACHE_METRICS_BREAKAT. This is the only user
of QTextLayout which did not have some kind of caching already.
For some weird reasons related to Argument-dependent look-up, the
qHash(docstring) function has to be defined in std namespace, since
lyx::docstring is actually std::basic_string<wchar_t>.
[NOTE: this version has profiling hooks, enabled by commenting out the line
#define DISABLE_PMPROF
that should eventually be removed.]
In fact having an extra parameter "bool cond" is no longer useful because it can
now always be emulated with a ternary operator:
Changers dummy = cond ? do_change() : Changer();
A static local variable is guaranteed to be initialized only once, and in time.
Lambda expressions can be used to perform complex initialization of those static
variables on the spot.
(starting from: gcc >= 4.8, msvc >= 2015)
The function is no longer used in LyX's sources (as of the previous
comit, 9b64d7bd) and is thus removed with this commit. Perhaps the
advantage this function had over other path functions we have has
disappeared over time (see e.g. 1a7b7f65).
The only exceptions are:
- The purpose of the header is to drag in the used symbol, e.g. unique_ptr.h
- The used symbol is inside a class or a namespace other than lyx
The reason for this is that global 'using' statements effectively forbid to
use the used symbols in any other namespace in the whole program, since simply
adding or removing an #include of the corresponding header subtly changes the
name lookup. The namespace lyx is sort of global, so it should not have these
statements either.
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).
Boost.Signals is deprecated. This fixes bug #9943.
The only thing left to do is to rewrite (or get rid of) the boost -mt test
in config/lyxinclude.m4 not to use signals anymore.
It is no longer needed to create fake copy constructors and assignment and to
deal with deletion by hand, thanks to unique_ptr, the inference of move
constructor and assignment operator, and the compatibility of standard
containers with movable objects.
Two better ways of making a class non-copyable in C++11:
* Store the p. impl. in a unique_ptr (for the cases of classes with p. impl.),
or:
* Define publicly the copy constructor and assignment as deleted
Lots of other classes could be cleaned up in this way.
As discussed on the list. If no C++11 compiler is found configuration stops
with an error. There are now unneeded parts of boost, the will be removed in
a second commit.
It turns out that it did not take off since introduced in 2011. It is better to remove it and the associated boost headers (extract.sh was run against boost 1.60 to do the update).
Since we will move away from several boost classes when transitioning to C++11, it is good to start by removing lesser used ones.
It is easier to use instead getVectorFromString for the use we have of this tokenizer. The two places are environment.cpp (path stuff) and qt_helpers (file fileters). The new code is much shorter.
This allow to remove boost/tokenizer.hpp and friends from our boost tree.
Compiling different parts of the sources with different WINVER may lead to
subtle and hard to detect problems. Better use the same value everywhere.
The existing error message suggests that this was wanted anyway, and it
fixes a compiler warning when cross-compiling for mingw on linux. Our code
does not require a specific value, only a minimum value of 0x5000, which
means the resulting executable will require at least Windows 2000.
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.
On mingw-w64, long long (64bit wide) is larger than long (32bit wide).
Therefore we need some more specializations for string, docstring,
otextstream and << overloaded ostream functions. The configuration code
is by me, the source code changes by Shankar Giri Venkita Giri (bug 10053).
This is needed for warning-free compilation with mingw-w64, and does not hurt
for other build configurations. Patch by Shankar Giri Venkita Giri (bug 10053).
This fixes a failing unit test with 32bit gcc 4.9.3 and -O2 optimization:
It computed 9953 instead of 9954 for Length::inPixels() of value 2342.
The reason for this is probably different rounding behaviour caused by storing
the unrounded value in a processor register (uses 80bit accuracy) vs. writing
it back to memory (uses 64bit accuracy). The unrounded value is very close to
9953.5 (which is not representable as an exact IEEE floating point value).
Apart from that, having a proper function for rounding makes the code more
readable, and has the nice side effect to make Length::inPB() work for
negative lengths as well.
We open the input file now twice: The first time in latin1 encoding to read
the document encoding from the preamble. This does always work, since
traditional TeX does not allow non-ASCII contents without an encoding changing
command (except for comments, but we do not need them, and using latin1 rather
than utf8 ensures that they do not produce an iconv exception, but are simply
recored with wrong characters), and we do detect the utf8 based TeX engines
XeTeX and LuaTeX as well. The second time we open the file directly with the
document encoding.
This fixes a few tex2lyx tests on OS X, since changing the encoding of an
open file steam does not work with clang on OS X. Files using more than one
encoding are still broken, but all single-encoding files are fixed now.
Changing the codecvt_facet of a file stream after the file has been opened
does not work with clang on OS X. Therefore we avoid it if possible (i. e. the
new encoding is the same as the old one).
External processes cannot access files which are open in LyX. Therefore the
temp files created by the external inset need to be closed right after
creation. The symptom was that the date inset did not produce any outout on
windows (bug 9925). This change reverts a small part of f09a9fe2.
Although the date inset is unimportant and will probably be removed, this
change is important for all external insets that make use of temp files.
boost::regex supports escape sequences starting with a backslash in format
strings of regex_replace, but std::regex does not. Therefore format strings
involving literal backslashes have to be written differently for both flavours.
The special MSVC handling in regex.h is removed, since it is not needed
anymore, and using grep syntax would definitely be wrong.
The changed code is not used, but I tried to use a similar approach for
boost::regex, and found some problems:
- regex_replace and regex_search are implemented in the replacement, so they
must not be used directly
- an smatch object must be given by reference (as in the called methods),
otherwise an exception would be thrown at runtime
- the commented out regex_replace version is actually needed
This code is supposed to be deleted, but nevertheless I wanted to record here
how it had to be modified if it was actually needed.
Other than BIBINPUTS, also BSTINPUTS and TEXFONTS are exported.
They do not replicate the setting for TEXINPUTS but are set such
that the current dir (i.e., the temp dir) and the document dir
are also searched for bibtex and fonts related files.
Remove member disp_ that is defined both in Cursor and CursorData classes
Pass parameter of convert<T>(docstring const) templates as const reference for performance.
This was made visible by aab1b145a5, since xhtml export for
lib/doc/Additional.lyx caused an exception. However, the cause for this was
already present earlier: All attempts to output a std::string to an
odocstream resulted in trying to change the encoding of the stream instead,
since there is no operator<<(odocstream &, std::string) defined, and an
implicit conversion to SetEnc happened instead.
This is fixed by making the SetEnc constructor explicit and adjusting all
code parts that did not compile anymore after that. The parts of the code
that did use the wrong output operator were the std::string version of
htmlize() from output_xhtml.cpp and all changed parts in the other .cpp files.
I also removed the std::string versions of html::htmlize() and
html::cleanAttr(), since it was difficult to see which encodings were used
with these. Now we are always explcit when using html::cleanAttr() and
html::htmlize().
These were found by cppcheck:
Member variable 'x' is not initialized in the constructor.
The crash #9788 would not have happened if this had been done earlier.
Use the function support:truncateWithEllipsis() to shorten a docstring with
... at the end. Actually we use U+2026 HORIZONTAL ELLIPSIS instead of "..." when
automatically shortening strings. This is to be consistent with Qt's own
truncation and is much nicer on the screen.
This includes the bugs #9575 and #9572 regarding broken text elision in the
outliner.
Known issues (non-regressions):
* TocBackend::updateItem() should be rewritten to update all TOCs. (#8386)
* "..." should be replaced with … everywhere else on the interface (including
translation strings).
* We should prefer to rely on QFontMetrics::elidedText() to truncate strings
with an ellipsis whenever possible, or an equivalent for the buffer view
dependent on the font metrics. See the warning in src/support/lstrings.h.
These were all flagged by "(style) The scope of the variable 'x' can be reduced."
Narowing the scope improves readability, and if it is in a loop then the
compiler will be clever enough to produce efficient code, we do not need
manual optimization for POD types.
These were all found by cppcheck. Even in constructors that are there "only
because of std containers" the class should be initialized correctly. You can
never know whether such an object does not get used, and then a nice crash
caused by dereferencing a NULL-pointer is better than undefined behaviour.
The 'using namespace std' at the top of the file makes it quite difficult to
understand which abs is used: double std::abs<double>(double) or
int ::abs(int)? Now it is explicit, and the code does not change in subtle
ways if somebody removes the using statement.
This replaces tests for __cplusplus >= 201103L, which are wrong with gcc 4.6 and earlier. Indeed these versions of gcc define __cplusplus = 1.

Newer boost versions use complicated type traits for boost::next and
boost::prior, which do not work with the RandomAccessList iterators.
The long term solution is to use std::next and std::prev, for now supply
simple replacements for compilers that do not support C++11 yet.
This fixes hopefully the compilation of check_trivstring on cygwin and
solaris. Previously I did not use the explicit instantiation, because c_str()
is used by other explicitly instantiated methiods, but for some reason this
does not seem to suffice.
LaTeX lengths must not use scientific notation, since the + sign has a
different meaning (glue lengths). This is the export part of bug 9416, the GUI
part is still not fixed.
The "save-as" part of the bug is fixed by extending the \textclass tag
such that, if a local layout file is used, its path relative to the
document directory is now stored together with the name. If a relative
path cannot be used, an absolute one is used but, in this case, the
document is not usable on a different platform.
The "copy" part is fixed by introducing a new \origin tag, which is
written when the file is saved. This tag stores the absolute path of
the document directory. If the document is manually copied to a
different location, the local layout file is retrivied by using
\origin (which is only updated on save).
This new tag may prove useful also for locating other files when the
document is manually moved to a different directory.
As in the original implementation the files needed for the layout
(for example, a latex class) had to be in the same directory as the
layout file, this directory has also to be added to TEXINPUTS.
We claim that gcc 4.x is needed in INSTALL, so it does not make sense to keep
this old stuff. Instead, I made configure output an error if gcc is too old.
The GNU libstdc++ that ships witch gcc 5 can be used with the same ABI as
older versions, or with a new ABI which is conformant to the C++11 standard.
LyX did not build if the latter was used:
https://kojipkgs.fedoraproject.org//work/tasks/1267/9651267/build.log
This is now fixed by detecting the ABI version and disabling the wrong forward
declarations. At the same time, STD_STRING_USES_COW is switched off for the
C++11 ABI version, because the std::basic_string implementation is now C++11
conformant. Since the GNU libstdc++ can also used by other compilers such as
clang, we must not test for the compiler version.
This fixes a situation where LyX did not detect that something went
wrong (that an external comman crashed) and reported that export was
successful. To reproduce, use the following version of LuaTeX (the
bug in LuaTeX causing the crash has since been fixed):
LuaTeX, Version beta-0.79.1 (TeX Live 2014) (rev 4971)
Then open FeynmanDiagrams.lyx and export with PDF (LuaTeX).
In the documentation [1] for QProcess::exitCode() it states:
"This value is not valid unless exitStatus() returns NormalExit."
For more information, see:
https://www.mail-archive.com/lyx-devel@lists.lyx.org/msg185317.html
[1] http://doc.qt.io/qt-5/qprocess.html#exitCode
I am moving the corresponding code directly to InsetInfo.cpp.
Moreover, the size of the image displayed by the info inset is
now dynamically set according to the text size.
It is better to introduce a dummy blank dir in TEXINPUTS rather than
appending a blank at the end. Even if I have checked that this is not
a problem with MikTeX, some other engine (maybe texlive, but I cannot
check) could not ignore this space and take it as the name of a dir.
In this case, TEXINPUTS would not end with an empty element and the
standard search path would not be inserted there.
If a compressed svg icon is present, load it instead of a png one.
Also introduce two more sizes (huge and giant icons) that should be
useful when using hires displays, as svg icons automatically scale
to the desired size without loss of quality.
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.
This resolves a dependency of src/support/docstream.cpp on src/TexRow.cpp,
which is the wrong way round. This fixes the linking
src/tests/check_ExternalTransforms with MSVC where the linker is not clever
enough to detect that the whole otexstream class is unused.
