Create new helper class UndoGroupHelper, which simplifies a lot the
handling of undo groups in cases like this one. The class tracks open
undo buffers and allows to switch buffers transparently.
Using the class for advanced search and replace is trivial. THe class
may be useful in some other classes.
Fixes ticket #8658
Add a new tag HasGuiSupport to language file. Add it for all l10ns
that we currently ship. The po files that are unused are not currently
tagged as available, but this could be done, since the code later
checks that the translation is actually there.
This new information is used in GuiPrefs when populating the language
combox.
The new scheme implies that adding a new language is now a two-step
process:
* the language code has to be added to po/LINGUAS, as before;
* one of the entries of the lib/language file has to be selected as
reference and be given the "HasGuiSupport true" property.
This leads to better compatibility with e.g. arXiv.
As Jürgen notes, it is also possible to override this automatic
empty pdfborderstyle via the Additional Options.
Patch by Julien Rioux.
The cleanup in 11ca1406 was not correct. It is actually not possible to implement recordUndoInset from the undo API, since the cursor may not be at a different level than the text to be saved.
Fixes ticket #9553
This replaces tests for __cplusplus >= 201103L, which are wrong with gcc 4.6 and earlier. Indeed these versions of gcc define __cplusplus = 1.

LaTeX lengths must not use scientific notation, since the + sign has a
different meaning (glue lengths). This is the GUI part of bug 9416,
on top of part 1 [59e4d16ab/lyxgit].
\framebox{} is equal to \fbox{} and \makebox{} is equal to \mbox{}
When I once wrote this code LyX did not support \fbbox and \mbox and therefore had to use a workaround.
- the idea is to color the box inset frame according to the fame color of the box (if there is any). To keep the WYSIWYM principle the frame thickness and box separation are not taken into account. However this should be possible if anybody would like that.
- besides this, use the correct conversion command for the background color
The math parser could not handle multicolumn grids. This is a problem because
there is no true ERT in math (everything is parsed).
Now multicolumn cells are parsed correctly. The display is also somewhat OK,
but apart from that any multicolumn related UI is missing. Since the file
format change is now done the UI can be added at any later point. The most
important part of bug 396 is now fixed: tex2lyx does not create invalid .lyx
files anymore for formulas containing \multicolumn.
I updated the tex2lyx test cases that produce correct output. tex2lyx does
still produce invalid output for the test cases which are not updated because
of the previous format change.
There were now 2 entries named "none" in backgroundcolorCO
- delete the fixmes; the LateX name is used as parameter to save unnecessary conversions for the LateX output; please ask me before adding fixmes
It is now possible opening documents that where manually moved to a
different location after they were saved and still produce an output.
Indeed, (hopefully) all needed included files are now still found.
When the moved document is saved again, all paths are accordingly updated.
Of course, for this to work, a document has to be saved in Format 490,
at least.
As an example, after converting the user guide to the last format, it can
be copied anywhere and opened without the need of adapting the paths of
included files or moving them to a proper place.
There is one glitch I am aware of. When moving a child document (but not
the master) the path to the master is correctly updated but it won't be
recognized as such. This is because LyX checks that the parent actually
includes this document but, of course, being the parent document not
touched, it appears not including this child. Anyway, it will also occur
when saving the child to a different location and the user is warned
on the terminal about this fact when the moved child is loaded.
However, there is no problem when it is the master that has been moved.
We also get a consistent look with amsmath, so require esint or amsmath.
When resolving alternatives, do also take into account whether the package
is available. For this to work, we also need to test for amsmath.sty (which
was surprisingly not yet done).
stupid me, I used a translatable string as box parameter. Therefore the feature only worked correctly with English locale. Now it works for every locale.
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.
Revert "tex2lyx testfiles: update to latest fileformat"
This reverts commit afdfc3cf43.
The tex2lyx test vrefernces must be produced by tex2lyx, otherwise the tests
would still fail.
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 command "paste pdf" was always disabled because the
condition in the following "if" statement always returns false
if (arg == "pdf" && (type = Clipboard::PdfGraphicsType))
The value of "type" is zero in this case because PdfGraphicsType is
the first enum value (and it is not set explicitly to non-zero).
An alternative patch is to put AnyGraphicsType as the first
element of enum GraphicsType, or to set the first element to a
number greater than 0.
To test the bug that this commit fixes, either copy a PDF and try to
paste with the action "paste pdf", or click on the "Edit" menu and
notice (before this commit) the terminal output "Unrecognized
graphics type: pdf".
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 is still a hack, but a less dangerous one. The old code had a problem
if it was called from different threads, or if for some reason it would get
called recursively.
The document iterator now skips math insets and insets like notes where spell check is disabled.
The continuous spell checking is part of the row painter drawing and the spell check disabled state
has to be passed down recursively while doing the inset painting.
Because of our better mechanism for dealing with errors (72c5385f),
the problem described in the comment is no longer possible.
NO_OUTPUT is treated as an error so there will no longer be a
lingering PDF in this case.
As Enrico said, the user might have installed a package that was
missing (in which case the .tex file would not have changed).
Another reason is that changing some document settings did not
automatically lead to a fresh compile after an error (#9061).
Our old mechanism for detemining whether there was an error was to
check if the dependent file existed in the temporary directory. If
it did not exist, that meant it was removed, presumably because
there was an error during compilation. That mechanism cannot be used
anymore because we keep the files around even after error because of
the "Show Output Anyway" button (09700d5b). This commit implements a
more straightforward way of checking whether there was an error in
the previous preview by simply storing the success of last compile
in a buffer variable.
The problem was due to the use of the wrong symbol for the slash.
The zero-width symbol for the \not operator was being used.
Using TeX fonts for all symbols gives now a better uniform look.
It is not possible using the alternative code even with Qt 5.4.1
because some glyphs are still missing.
Avoid that \newcommand[x] definitions of math macros are pushed multiple
times to the preview loader.
Redefinitions (via \renewcommand[x]) are properly handled.
The preview snippets are cached in a seemingly random order, such
that, when regenerating them on zoom, the math previews would be
numbered accordingly. Hence, we have to go through the insets to
get the correct order. This is a bit slower but unavoidable.
Note that I move the definition of cur up because we need to check if
it changed before the return. I also removed the const because
notifyCursorLeavesOrEnters() requires that.
This commit probably fixes other issues for any inset that defines
notifyCursorLeaves().
This fixes only part of #6173.
The reason we want to do this is for if there is pasting across buffers.
For within buffer, the previews should already be updated. Calling the
buffer-wide updatePreviews() might seem like overkill, but actually it
should be quick because only the previews that need updating are updated
(and this check feels quick to me, although I did not profile).
If we were to loop through the pasted text and update each preview
individually, this might take more time. When updating previews
together, only one .tex file is compiled.
Normally the theBufferList().updatePreviews(); statement would go inside
of PrefDisplay::applyRC. However, that would not work well because
Buffer::updatePreviews() calls loader() which conditions on
(lyxrc.preview == LyXRC::PREVIEW_OFF) but the new RC has not been set at
this point.
When editing a preview inset, or math, when we leave the inset, we
should update the preview. This update now happens for screen-up and
screen-down (commonly bound to Page Up and Page Down).
Note that this is only relevant if preview is turned on in
preferences.
This commit probably fixes other issues for any inset that defines
notifyCursorLeaves().
This fixes only part of #6173.
Sometimes, even compilable documents could not display preview
snippets. Previously the preview was computed only with help
of latex or xelatex.
This also fixes#9371
The FontMetrics dummy class was in the wrong namespace. Linking on linux
did work because the GNU linker is more clever than the MSVC linker for this
particular example and throws out more unused code, so that theFontMetrics was
not referenced at all.
Control + Shift + PgDn now moves a tab to the right.
Control + Shift + PgUp now moves a tab to the left.
These keybindings are consistent with Chromium, Firefox,
Nautilus, and gnome-terminal.
Note that I allow for wrapping. This is consistent with
allowing wrapping for buffer-{next,previous}, but there
might be reasons to disable it in the future.
buffer-next and buffer-previous are now only enabled
if there is more than one tab. Note that it does not
matter whether we are at the first or last tab because
we cycle.
Since the logout process still can be canceled here, we should only
check that all dirty buffers are saved and that the session state is
recorded.
Please test, particularly on Windows and OSX, that logging out with LyX
running (both with and without dirty buffers) proceeds sensibly and that
the LyX session is correctly restored when you re-login.
We currently cannot restore multiple views of the same buffer properly.
On the mac, we even crash.
So do not try it, record each file only once in the last opened list.
Fixes: #9483.
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
Building on cd8be655, we still allow viewing a produced PDF even if
there were compilation errors. However, now the user must click the
"Show Output Anyway" button in the LaTeX Errors dialog. The reason
is that before, there was a chance that the user would not realize
there was an error (because the PDF would be shown over the error
dialog). The approach in this commit makes it more clear that there
is an error.
A new LFUN is introduced, LFUN_BUFFER_VIEW_CACHE. It is useful not
just for the implementation of the "Show Output Anyway" button, but
also to show the last compiled version of a document, which can save
time if a document takes a long time to compile (e.g. heavy use of
knitr).
When at the last position in an inset, selecting to the right
should select the entire inset. This only worked if there was
already a selection (i.e. the selection was started not at the
boundary).
The behavior of this bug was changed by commit 73a7bf9d. Before
that commit, if at the last position of an inset you select to
the right, nothing is selected but the selection is set. If you
select once more to the right, because the selection is set the
needsUpdate condition is satisfied so the whole inset is selected.
Note that everything here applies also to "first position of an
inset" and selecting to the left. By "selecting", I am referring
to LFUN_{CHAR,WORD}_{FORWARD,BACKWARD}_SELECT.
In the test case the crash occured in mathml export of the temporary buffer,
because the macro was updated, and because one of the used other macros was
not copied, the macro argument was detached. However, the underlying problem
of the crash was a broken ArgumentProxy::mathMacro_ reference which became
invalid each time the ownng MathMacro was copied. In the bug test case the
copying happened due to resizing a std::vector, but any other copy would have
created the same problem. The crash did not always happen, because sometimes
the old freed memory was not immediately reused, so the invalid reference did
still point to usable data.
The fix is easy: Convert ArgumentProxy::mathMacro_ to a pointer and update it
always after creating a copy of the owner. The pimpl of MathMacro from the
previous commit helps here to distinguish between the data that can be
automatically copied (in MathMacro::Private) and the cleanup that needs to be
done manually (in MathMacro). This way, the manual copy constructor and
assigment operator of MathMacro does not need to be touched if a new member is
added.
* Remove the UndoKind parameter in the general interface
* move recordUndoInset to Cursor
* remove one variant of Undo::recordUndo.
* get rid of Text::recUndo.
The only real user was Text::insertStringAsLine, but this got changed
in commit 2c7152ab.
While not other place did read the value, there is a side effect of
setAutobreakRow that merges exiting paragraphs. However, this is used
in two situations
* some constructors, where the inset is empty;
* InsetTabular::toggleFixedWidth, which actually contains itself some
code to merge paragraphs.
Therefore the member and all associated code can be removed safely.
Rely only on InsetText::allowMultipar() to get this information.
Implement this method for InsetTabular and InsetBox.
Also rely on this method for disabling LFUN_PARAGRAPH_BREAK.
* Disable "New Inset" button
* Do not disable line edits, but use setReadOnly instead (this allows copying contents)
Fixes: #9408
Note that some dialogs still need some care.
The expanded cells of a mathmacro were previously stored in an InsetMathSqrt.
This was only used as a container for the MathData object in the first cell
of the sqrt inset, which contained the actual expanded arguments.
Funny enough, the only place were the inset property of expanded_ was really
used cannot be seen in the diff. It was MathMacro::kerning(), and this usage
was wrong, since InsetMathSqrt::kerning() always returns 0. Threfore, using
the correct type (MathData) for expanded_ does not only make the code more
readable, gets rid of an unneeded dependency, but also fixes a bug: Now the
correct kerning is returned for expanded cells. Also, expanded_ and
definition_ use the same type now, which looks nicely symmetric.
Previously, things like [ name ] where exported for computer algebra systems.
Now, the expanded macros are exported, which may still be wrong, but now the
CAS has at least a chance to understand what was meant.
Currently, only lfun names are accepeted but there are cases in which
the lfun name does not map directly to an icon. Fore example, in the
outliner, the icon named "promote" is used for the lfun outline-out.
As a result, a graphics inset is used in the documentation for describing
the corresponding icon. Now one can also use an icon name. The argument
of "info-isert icon" is firstly lookep up as an lfun. If no corresponding
icon is found, the argument is taken as the name of the icon. If no such
icon exists, the "unknown" icon is used.
The computation of length on screen depend in particular of the computation of the size of an em. Many places of the code used to rely on the width of the M character, which is not really correct:
http://en.wikipedia.org/wiki/Em_%28typography%29
In digital typography, the best value to use is the point size of the font.
* Implement FontMetrics::em(), which returns the value in pixels of the EM unit.
Convert code to use it.
* Introduce Length::inPixel(MetricsBase const &), which takes the textwidth and em information from the MetricsBase object. Convert code to use it.
* Fix several places where Length::inPixel is used without a proper em value.
* add mathed_font_em() helper function. It should eventually be removed like some other functions in MathSupport.
* Add dummy implementation of FontMetrics to tex2lyx for linking purposes.
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.
This is a bug reported and fixed by Edwin Leuven.
Here is how Edwin described it in his inimitable minimalist style:
first i merge the top-left two cells in a small, say 3x3, table
if i then merge this multicolumn cell with the remaining cell in the first row
my table ends up all bonkers
This is the rersult of a discussion on the list. Now all special characters
have meaningful names, and it is clear that the LyX file syntax is not LaTeX.
Fixes crash introduced in [17e435c4/lyxgit].
editable() is more related to Texted. It is false for closed collapsable insets
Eventually the two methods should be merged.
Imagemagick detects the inut file format based on contents. Therefore it does
not make sense that we prefix the to be converted file name with the extension
(assuming that the file extension matches the imagemagick format name). This
breaks formats where the extension used by LyX does not match the imagemagick
format name.
I thought I would need it to fix bug #9418, but once backwardInset() worked
it turned out that it is not needed. However, since it took me some time to
figure out the correct implementation I do not want to throw the result away.
The concept of rows and cols is no longer unique to mathed.
Each inset decides itself whether it is grid like or not, so we should not
interfere with this in the cursor slice.
If LyX thinks the export was successful but no output file was
produced for preview, then something is wrong (most likely LyX
did not detect an error that occurred during export).
Also clean up some logic.
A PDF is often still produced after a LaTeX error.
If there was an error when exporting a PDF, we now give an error
and the PDF (if it exists), where before we gave the error and
not the PDF. The GUI and command line behaviors are consistent:
in the GUI an error is given and the PDF is viewed; on the
command line, a non-zero exit code is given and a PDF is created.
This also solves what was in my mind an inconsistency: if the user
"updated" a document and there was an error, the resulting
PDF would be shown; but if the user viewed a document and there
was an error, the document would not be shown.
Note that this applies to all output formats, not just PDF.
For discussion, see:
https://www.mail-archive.com/lyx-devel@lists.lyx.org/msg186454.html
When scanning the LaTeX log, previously we only looked ahead 10 lines
after a "!" line and if we did not find a line number we did not count
an error. This lead to the problem that templates/ACM-sigplan.lyx was
showing a successful export and the PDF was shown (it is still
created despite the error). Now that the exit code of the latex
command is checked (as of the previous commit), an error is correctly
given, but by parsing the log better with this commit, a more
informative error is given.
Increasing the look-ahead to 15 lines leads to correct parsing of
the ACM-sigplan log. The excerpt in the log file where there are more
than 10 lines in-between the "!" line and the line number is below:
! Undefined control sequence.

Another example is posted here:
http://tex.stackexchange.com/questions/231655/lyx-cannot-output-to-pdflatex-for-a-specific-file
Systemcall::startscript returns the exit code of the LaTeX command
that is run, but the return value was not being checked by
LaTeX::run. Instead, we relied on parsing log files. However, this
parsing is not perfect.
The return value is now checked and if the exit code of the command
is non-zero, an enum value is added to the return and the user is
notified of the error.
At a higher level, if the LaTeX command returns a non-zero exit code,
in the GUI a message such as
"Error while exporting format: PDF (LuaTeX)" will be given instead of
"Successful preview of format: PDF (LuaTeX)".
When run on the commandline, lyx -e lualatex example.lyx
will give "Error: LaTeX failed" and a non-zero exit code
where before it gave a zero exit code.
A real example of the bug this commit fixes is LyX's (as of this commit)
ACM-sigplan.lyx template.
Before this commit:
$ lyx -e pdf2 ACM-sigplan.lyx
[...snip...]
support/Systemcall.cpp (288): Systemcall: 'pdflatex "ACM-sigplan.tex"'
finished with exit code 1
$ echo $?
0
Starting with this commit:
$ mylyx master -e pdf2 ACM-sigplan.lyx
support/Systemcall.cpp (288): Systemcall: 'pdflatex "ACM-sigplan.tex"'
finished with exit code 1
Error: LaTeX failed
----------------------------------------
LaTeX did not run successfully. The command that was run exited with
error.
$ echo $?
1
This was disabled in 2009 in bea0925f but it is now safe.
From Richard:
"I am pretty sure that all the work that Peter Kümmel did with the
InGuiThread classes dealt with this issue."
This commit solves two issues:
(1) A PDF from a previous run could have been the result of a command
that exited with error (e.g. sometimes pdflatex still produces a PDF if
it exits with error). If the "View" button were clicked a second time
without changing the .lyx file, then the checksum of the .tex file would
not have changed so LyX would show the PDF (which was created from the
first run that exited with error), and this time LyX would not report
the error (because the parsing of the logs only happens when the .tex
file is compiled).
(2) A myfile.tex that results in no output does not yield a myfile.pdf.
Thus, Any myfile.pdf in the temporary directory will not be overwritten.
Before this commit, the following scenario was possible: LyX runs
pdflatex which processes myfile.tex and no error is given so LyX opens
myfile.pdf. However, it could have been the scenario that pdflatex did
not exit with error and did not create myfile.pdf, in which case
whichever myfile.pdf is being shown is not correct. To see this bug in
action, start a new document, type "abc", view the PDF, delete "abc",
view the PDF (this correctly gives an error that empty output was
created), view the PDF again (this does not give an error because the
checksum has not changed). The PDF shown will contain "abc".
Note that the above also applies to DVI files and that the fix is
general.
Using fraction of points is a reasonable way to avoid warnings with fussy compilers.
Moreover, this fixes the output of PHRASE_LATEX2E to use the proper form \LaTeXe.
The file format still uses the questionnable form \\LaTeX2e.
The problem came from the fact that Qt associates Interlingua to locale C.
Now, we do not rely anymore on the Qt locale to set the language. I suspect that the problem will still exist if the system locale is ia_IA.
Fixes bug #9267.
The old scheme was:
* multiple insertions are undone by groups of 20
* multiple deletions are undone in one big block
The new scheme is to stop merging undo elements after 2 seconds of elapsed time.
Moreover, the merging of undo elements stops when the cursor has moved. Potentially, this could allow to remove many of the finishUndo() calls.
Fixes bug #9204.
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.
LyX did not display the limits of the big math operators defined by
stmaryrd.sty correctly. The reason for this was a missing check in
InsetMathSymbol::metrics(), where it is hardcoded which symbols use display
style limits and which symbols use inline limits. In an ideal world this
information would be contained explicitly in lib/symbols.
This should go to branch as well.
If a mask is missing, the TempFile class appends it to the filename.
This may be a problem with applications relying on the extension,
so explicitly add a mask.
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.
tex2lyx did not use the InsetLayout for the script insets, so it did not know
that it had to use Plain Layout. However, there is still a possible pitfall:
InsetScript uses a hard coded plain layout for the InsetText constructor, so
if anybody would remove ForcePlain 1 and MultiPar false from the InsetLayout
then LyX would still write script insets with plain layout, but tex2lyx would
output standard layout again.
We have some math macros that exist only because LyX can display them easily,
but which require user preamble code. These commands should not appear in
autocompletion, they are only there to make the formulas of users who actually
need thgese symbols and know what to put into the preamble more beautiful.
This avoids invoking the insert space dialog instead of the math version. Thereafter, spaces are correctly inserted inside macro templates.
This is the last part of the fix to #9432.
Additionally, move the code to write to a stream from Cursor to CursorData (so that debugging undo is easier). We loose x_target, but I am not sure it is important.
This is the second part of bug #9432.
Previously, LyX did replace some words with typeset logos, and there was no
way to prvent this except putting them, in ERT (bug #4752). Now we have
special insets for these words, and standard text is left alone.
Previously, tex2lyx did not remove the \protect which is output by LyX in
front of \nobreakdash- if needed. Now tex2lyx removes it unconditionally (like
it does elsewhere), because LyX will add it if needed.
The old hyphen replacement code did not convert hyphens if the condition
style.pass_thru || runparams.pass_thru
was met. style.pass_thru got set from inset owner (isPassThru()). Therefore
we have to consider this for the new replacement code as well.
Previously, consecutive dashes in .lyx files were combined to endash and emdash
in some cases, and in other cases they were output as is. This made the code
complicated, and resulted in inconsitencies ((bug #3647).
Now, a dash in a .lyx file is always a dash in the output, for all flavours.
The special handling is moved to the input side, so that you still get an
endash if you type two hyphens. If needed, this can be changed or made
customizable without the need to update the file format again. Many thanks
for the fruitful mailing list dicsussion, which contributed significantly to
the final version.
Again thanks to Scott for finding this. The removal of the check for full
unicode in eb121f999 was not wanted. Now listings can be exported to
lualatex and xetex again.
Thanks to Scott for testing. If a macro is unknown (displayed in red), then
macro_ is 0. The LATTEST is now adjusted and works like in MathMacro::write()
where I stole it from.
For exports based on LaTeX, consecutive hyphens are only converted to endash
and emdash if the current font family is not typewriter, and if none of the
parent insets is an IPA inset. Now this is done for XHTML export as well.
The math icons for the symbol image in the math completer were hardcoded to the
command names. This is wrong for some icons for various reasons, e.g. the case
insensitivity of windows file systems. Therefore we have to use the replacement
list which is also used for the toolbar icons. Bug #3538 is not closed because
of this problem, but IMHO it has nothing to do with this bug, it is a more
general one.
There are several places in the code where a row is painted with drawing disabled in the painter. The goal is only to recompute inset positions.
Such a case happens in BufferView::checkCursorScrollOffset, as part of the horizontal scrolling patch. Note that this particular piece of code should eventually be removed, since it is a performance problem.
It makes sense to consider that only a real painting of a row should change its status. However, I would not be surprised if this change would break other things.
Fixes: #9388

The textcyr test did not work anymore, since the output of
"CYRILLIC SMALL LETTER VE" changed from \textcyr{\char226} to \textcyr{\cyrv}.
The the old version is now converted to ERT. In theory it could also be
converted to "CYRILLIC SMALL LETTER VE", but this would mean to maintain an
extra list, which is not worth the effort.
Rename recordUndoFullDocument to recordUndoFullBuffer.
Separate the notion of recording changes to paragraphs and recording changes in buffer parameters.
Audit every user of recordUndoFullDocument and replace it with either recordUndoBufferParams or recordUndoFullBuffer. Add comments to identify remaining work.
After the str-metrics merge, the kludge for displaying symbols whose
code point corresponds to a soft-hyphen was not working anymore.
The solution is replicating the offending glyphs with index 0x00ad
at a different index. They were replicated at 0x00ac, whose glyph
was missing in all affected fonts.
However, this would not work by alone because, if a system font with
same family name exists, it would be picked up instead of the right one
(at least on non-Windows platforms). For this reason, the style of the
fonts has been changed from "Regular" to "Lyx", so that we can discriminate
the right font. However, this requires using at least Qt 4.8. If an
older Qt is used *and* a system font with same family name is already
available, the affected glyphs will all turn out on screen as the
"logical not" symbol.
I have also set the executable flag on the font files, because on Windows
they are loaded only in this case.
This solves #9229.
The problem was that the conversion to plain text (which is used as an
intermediate step) requires for some insets a valid buffer pointer, but
insets in the cut stack do not have one. Now we use the same temp buffer
business as for copying to the external clipboard.
This commit fixes a thinko in [8bab2338/lyxgit] causing the warning:
QObject::connect: No such slot lyx::frontend::GuiPreferences::slotApplyRC() in ../../../../src/frontends/qt4/GuiPrefs.cpp:3308
QObject::connect: (sender name: 'applyPB')
QObject::connect: (receiver name: 'PrefsUi')
This fixes the -geometry command line option and restores the
"Use icons from system's theme" checkbox in the preferences.
There is still code addressing Qt4 and xlib that has to be
audited. This code cannot be compiled with Qt5 because the
default backend is now xcb and not xlib. I have marked such
code with a "FIXME QT5" comment.
The listings package employs some dirty tricks internally, therefore it does
not work with utf8 encoding, but requires fixed width encodings. This version
of the fix uses ugly hardcoding instead of a layout file format change, so it
could be backported if needed.
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.
* \caption does not need to be protected in general
* the contents of \caption arguments need to be protected, though.
All styles related to caoption inset have been audited and updated.
The special casing of captions in longtables has been removed, since there is no special case.
Fixes bug: #9177
This implement horizontal scrolling of rows to allow editing insets
(math, tabular...) that are larger then the screen. The scrolling happens
as the cursor moves, in order to make sure that the cursor is always visible.
This effectively closes an 11 years old bug.
This feature is the result of the work of Hashini Senaratne as part of
Google Summer of Code 2013. The code has been cleaned-up for inclusion
and remaining bugs have been fixed.
Fixes bug: #1083.
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.
* When doing a redraw with drawing disabled (to set inset positions properly), take horizontal scroll offset in account
* reset horizontal scroll offset when it is smaller than the left margin.
* when drawing a paragraph, do not modify x globally, only for the row that is offset.
The new code should feel a bit more natural. It avoids explicit pixel values for the margins and does not scroll in some cases where it is not necessary.
[This commit is the output of the "horizontal scrolling" GSoC 2013
project, by Hashini Senaratne. The code has been cleaned up, some
variables have been renamed and moved from the Cursor class to
BufferView::Private. This is the base from which I (jmarc) will polish
the feature for landing on master.
Below is the original commit log of Hashini, updated to reflect the
changes that have been done.]
This feature also applicable for other insets; graphics and labels.
This implementation is capable of scrolling a single row when reaching
its content which is beyond the screen limits, using left and right
arrow keys.
The attribute 'horiz_scroll_offset_' introduced in the
BufferView::Private class plays a main role in horizontal scrolling of
the wide rows that grow beyond the screen limits. This attribute
represents by how much pixels the current row that the text cursor
lies in should be get scrolled.
The main logic that is responsible for drawing the scrolled rows is
within the BufferView class, BufferView::checkCursorScrollOffset.
* The main logic is called via BufferView::draw.
* What this does is set the horiz_scroll_offset_ attribute in in order to
show the position that the text cursor lies in.
* To make sure that BufferView::draw gets involved when Update flag is
FitCursor, necessary changes are made in BufferView::processUpdateFlags.
Basically what the logic that used to set the horiz_scroll_offset_
does is,
* The row which the text cursor lies in is identified by a
CursorSlice that points to the beginning of the row. This is the
'rowSlice' variable used in BufferView::checkCursorScrollOffset. Acessors
are added to obtain this variable. Here row objects were not used to
identify the current row, because it appears that row objects can
disappear when doing a decoration update for example. This means that
comparing row pointers is not a good idea, because they can change
without notice.
* Stop calculations of horiz_scroll_offset_ variable, if metrics have not been
computed yet. Otherwise the calls to TextMetrics::parMetrics, calls
redoParagraph and may change the row heigths. Therefore vertical scrolling
feature may get disturbed. This is avoided.
* Using BufferView::::setCurrentRowSlice resets horiz_scroll_offset_
when changing cursor row. This is done in order to prevent unwanted
scrolling that happens when changing the selected row using up and
down arrow keys.
* Recompute inset positions before checking scoll offset of the row, by
painting the row insets with drawing disabled. This is done because the
position of insets is computed within the drawing procedure.
* Current x position of the text cursor is compared with the
horiz_scroll_offset_ value and the other variables like row.width(),
bv.workWidth(). Compute the new horiz_scroll_offset_ value in order
to show where the text cursor lies in. The basics conditions that we
check before recomputing it are, if the text cursor lies rightward to
the current right screen boundary, if the text cursor lies leftward
to the current left screen boundary, if the text cursor lies within
screen boundaries but the length of the row is less than the left
boundary of the screen (this happens when we delete some content of
the row using delete key or backspace key).
* Change update strategy when scrooll offset has changed. This allows to
redraw the row when no drawing was scheduled. By doing so, it was
possible to redraw a wide row when moving to the leftmost position of the
wide row, from the leftmost position of the row below, using the left
arrow key.
In TextMetrics::drawParagraph it is checked whether the current row is
what is drawing now. If it is so, the value used to the x value of the row
for drawing is adapted according to BufferView::horizScrollOffset.
The method used to pass boundary() was fixed to get row when cursor was in
a nested inset. This matter is considered in Cursor::textRow and it is
modified accordingly.
GuiWorkArea::Private::showCursor() is modified to show the cursor position
in a scrolled row.
This happens when part of the word is selected.
To reproduce:
1. Start a new document
2. Type "af"
3. Select 'a'
4. Observe that the right part of the 'f' is clipped away.
This patch uses QRegion to set a clip region that is everything except
the part that is drawn in another color.
Fixes: #9223.
This is the first part of bug #8553. \textgreek was interpreted as the
polyglossia version even if polyglossia was not used. Now it is not recognized
at all and converted to ERT, but this ensures at least correct LaTeX output.
Actually I wanted to do that in cc87f8100 but forgot to adjust the original
solution completely. Now we do not search for an arbitrary latexkeys instance
which just happens to have the same name as the macro, but we only use the
symbol that was explicitly set for global macros.
Previously tex2lyx did ignore table columns if the column specifier was
unknown. This can lead to data loss, and now it does not ignore these columns,
but assumes that the column specifiers use only once character. This can still
lead to data loss, but less often.
If the user gave the -fixednec argument to tex2lyx then set that encoding as
LaTeX input encoding in the generated LyX file. Otherwise, included .bib files
could be interpreted using a wrong encoding.
It works with gcc >= 4.9.0 and clang (with libc++ or gcc libstdc++ from gcc
>= 4.9.0). The MSVC parg is missing, because I cannot test it, and the
autotools build still link against boost::regex even if it is not needed, but
I don't know how to fix that.
Now we can handle all types of captions defined in layout files or modules.
This does also mean that \captionabove and \captionbelow are only recognized
in KOMA-classes and not always anymore, but this is correct, since these
captions would not work in other document classes anyway.
As discussed on the list. We don't need it anymore, either we have a modern
compiler that supports C++11, or we fall back to boost. I kept and adjusted
the regex #define, since we cannot use std regex completely yet.
This fixes the tex2lyx test test-refstyle-theorems.tex. It seems that the
intent of the fix was to remove a \protect in front of a \caption,
\captionabove or \captionbelow, but the implementation did not really do that.
Furthermore, it is not clear in which cases a \protect in front of a caption
needs to removed, and in which cases it needs to be kept: After looking at the
LyX sources I could not see that caprions are always output with \protect.
All the code that is run before row metrics have been computed should use int arithmetic. After metrics have been computed, we still need doubles because fully justified rows use double for Row::Element::extra.
Rename Row::x to Row::left_margin and change its type to int.
Rename Row::Element::width() to full_width(). In some places of the code, use dim.wid (the int version without the extra separator) because metrics have not been computed.
Let Row::Element::x2pos take a int& argument instead of double&
Let Row::Element::breakAt take a int argument instead of double
This patch fixes a series of warnings like:

3 different strategies have been used:
* in frontend, some functions have been renamed.
* in InsetMath.h, Inset::write has been explicitly imported too
* in InsetMathNest.h, since a comment said that hiding Inset::metrics is intended, a special trick has bee used to silence the warning.
This is needed since all formats are stored in a global list which is shared
between threads, but never modfified except from the main thread.
The only missing bit is extension_list_, which is not so easy to do.
If we compile in C++11 mode, do not use the boost replacements for bind,
functional and shared_ptr. regex is excluded, since it misses match_partial, and
gcc does not provide a usable one in versions less than 4.9.0.
I also removed the #define for match_partial, since this is dangerous. Now you
get a compile error instead of subtle runtime differences.
The old detection did only work if CFLAGS contained -std=c++11, since ciso646
was only included for __cplusplus > 199711.
Thanks to Koernel for the cmake part.
Now all const methods may be called without additional locking.
This is assumed by the threaded LaTeX export, which always useses a globally
unique instance for each encoding.
Read-only access to these classes is now threadsafe, with one exception:
The encoding neds to be already initialized (i.e. init() must not be called).
This makes bug 9336 unreproducable on my machine, although it is not completely
fixed yet.
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.
As discused on the list. This is not used yet, but it is intended to provide
thread-safe read-access without the need for synchronization if the used STL
implementation does not provide it for std::basic_string. This is the case for
all implementations using copy-on-write.
docstring is already defined in strfwd.h (which is included from docstring.h).
There are only two possible cases:
Either the typedef in docstring.h defines an identical type (then it is not
needed), or it defines a different type (then it generates a compilation error)
=> it is not needed.
The reason being that the TEXINPUTS path list was not quoted on Windows.
This was no problem with spaces but some special characters are
interpreted by the shell and can cause problems. In this particular
case, the '&' character was being interpreted as a command separator.
Thanks to Enrico, who noticed that the previous fix did not take into account
the case of nonempty length argument + the next line beginning with [.
Now the parsing is exactly the inverse of InsetMathGrid::eolString().
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__.
This allows to address two main issues
* \thanks does only accept one paragraph, while \footnote allows several (ticket #2666)
* footnotes in titling environments were not numbered on screen.
Moreover, the code reduces hardcoding of features, which is always a good thing.
There are several pieces in this commit:
* new numbering type \fnsymbol for counters
* the Foot inset changes its layoutName() to Foot:InTitle when inside a paragraph with InTitle property. This is set when running updateBuffer.
* Foot:intitle uses the \thanks command, does not allow multiple paragraphs and marks its contents as moving argument.
* The InsetLayouts for Foot now have properLaTeXName/Type, so that InsetFoot::latex can be removed; further code simplification is probably possible.
Fixes: #2666
There was an unsymmetry between reading and writing: InsetMathGrid::eolString()
adds curly braces if the first cell of the next line starts with [ to prevent
misparsing as optional argument of \\. These braces were not removed on reading.
Some applications do not accept forward slashes, so call external viewers
and editors with backward slashes which is the usual convention under windows.
The many occurances of the mutable keyword in LyX sources make it quite
difficult to understand what is really const and what not, and to debug
multithreading memory problems. In this particular case it is not needed
at all to have a mutable member, so make it non-mutable.
The advantage is that the buffer will no longer be
marked as dirty when converting to the same type.
A quick break here is done instead of disabling the
LFUN because disabling the LFUN would lead to a greyed out
entry, which might confuse users. In the future, we might
want to have a radio button for switching between notes.
The assignment name = sub.str(1) reads from the first argument given to
regex_match(), but previously this was a temporary object which was already
out of scope. This did probably not matter much in practice, but invoked
undefined behaviour, and as we all know this is allowed ton format your hard
disk or kill to your cat, so better fix this.
One declaration of doExport() was not used, and the other one was only used by
Buffer, so make it private since returning the exported file name is a bit
strange if it can also appear as input argument.
This makes the script usable on windows and speeds it up by an order of
magnitude, since no new process needs to be forked for each layout file.
It also does not conevrt .old files again.
This is different from bug #8999, since in this case a new macro instance is
created. You still get a TeX capacity exceeded error if you try to typeset the
exported document, but this is the same as for bug #8999 and better than a
crash.
This is a patch I originally sent to lyx-devel in 2012 with subject
'Load footmisc.sty instead of using copied code from obsolete stblftnt.sty'.
It now takes all comments into account: It works also if the user loads the
package herself, it can be disabled by providing the footmisc feature in a
layout, and it does not use the ugly \AtBeginDocument{}.
The symptoms are the same as the original #9224, but the reason is different. In the new code, the width of justified rows includes the Row::separator value. Therefore the CRC computed in ParagrahMetrics::computeRowSignature is not updated in some cases.
The fix is to add Row::separator as one of the elements of the row crc.
Fix a crash reported in #7727. This happened because cur.pos() was reset before cur.pit(). In this case, cur.lastpos() will usually be wrong.
Fix bad behaviour when selecting at top level with several paragraphs.
Update documentation.
BufferParams::setDocumentClass() deletes the old document class of the buffer
and creates a copy of the new one. Therefore, the stored layout pointers in
the paragraphs (actually only one paragraph exists) are dangling afterwards.
Resetting them before setting the document class helps here.
In the long term we need to get rid of BufferParams::setDocumentClass()
completely, this is very ugly.
Invoking a computer algebra system program for computing a selected
subformula has never worked (checked with all LyX versions back to 1.3)
and, moreover, in the presence of a selection things go awry.
This commit allows this computation by replacing the selected
subformula with the result of the computation.
A similar fix was reverted (453ce611) because of crashes.
The crashes occurred simply because of a failed check that
we have a buffer view before using it. That is now done in
this commit.
The below commit description is copied from the original
commit (fb05011a):
Empty selections can cause confusing behavior for a few reasons:
(1) some functions behave differently depending on whether there is a
selection. If I press delete, nothing happens (where I expect the
character or inset before the cusor to be deleted). If I toggle bold or
emphasize nothing happens (where if there is no selection the entire
word is toggled). There are other LyX functions that depend on whether
there is a selection or not. Further, I wonder if any part of LyX's code
assumes that if there is a selection it is non-empty.
(2) menu options are incorrectly set. For example, the scissors icon.
For remaining empty selection issues, see #9222.
For more information, see:
https://www.mail-archive.com/lyx-devel@lists.lyx.org/msg184758.html
Our TempFile class uses QTemporaryFile internally, and, on Windows,
this keeps the file locked so that we cannot rename it. So we have
to release the lock.
There are 3 possible actions (in order)
* select current cell
* select all calls of inset
* select the inset from outside (in the containing inset)
This fixes completely #7727.
The shape of the parbreak separator is slightly changed in order to
better distinguish it from the forced newline. This allows using the
same color of the plain version without risk of confusion.
The problem was that some parts of the code assume that the right margin is part of the width of the row. This is not the case, only the left margin (Row::x) is counted.
The code has been fixed and documented to reflect this.
Add display_pixel_ratio to buffer params to use it for displays with high resolution.
It holds the highest ratio between physical pixels and device-independent pixels of the LyX application.
Preview snippets will be generated using this value to get high resolution preview.
Add pixel_ratio to graphics params to use it for displays with high resolution.
It holds the ratio between physical pixels and device-independent pixels of the graphics.
Introduce the concept of pixel ratio: the ratio of physical and device independent pixels.
This is useful for rendering of content on Retina-displays of Mac hardware with high resolution.
Qt has real support for this starting with Qt5 - therefore it has to be compiled conditionally.
This change uses some work of Marcelo Galvão Póvoa, thank you.
What a selection spans several cells in mathed, and a deletion occurs though LFUN_CHAR_DELETE_FORWARD for example, only the case of a proper grid was handled. When no such grid exists, all cells between the first and the last index are cleared now.
If there is only one row, a new line should not be appended. If
there is more than one row, the new line should not be appended for
the last row.
For example, if in LyX there was "as you can see in $x$ there..." a
copy/paste would lead to a newline after "x".
lyxfind.cpp(findNextChange, findPreviousChange, findChange, selectChange): factor the change-selection part out of the change-finding part
Text.cpp (acceptOrRejectChanges): call only selectChange
mhchem loads amsmath and needs therefore be loaded after it but before packages that redefine commands of amsmath. We already take care of esint but not of wasysym
If we are testing tex2lyx the first time, then the userdir
is empty. We call now configure.py to initalize in case it is needed.
The algorithm to detect if reconfigure is needed mimics the lyx behaviour.
The check for a latex format is very fragile. Both libmagic and our
guessing from contents cannot distinguish the pstex and pdftex formats
used by the xfig external inset. Moreover, it may also happen that
lyx files are mistaken as latex ones. Thus, when the guessed format
is latex, the only solution is to give precedence to the format
determined by the file extension.
This commit replaces almost all occurrences of Q_WS_WIN to comply
with Qt5. The remaining occurrences should *not* be replaced,
because the guarded code won't compile on Qt5.
The command line argument -geometry WIDTHxHEIGHT±XOFF±YOFF
specifies a preferred size and location for the main window.
Currently, this is semi-broken on Windows. Indeed, only
specifying WIDTH and HEIGHT places the main window such that
the left and top borders are invisible such that the window cannot
be moved. Moreover, the XOFF and YOFF parts (when present) are
used to specify the distance of the window from the left and top
or right and bottom edges of the screen, when using '+' or '-',
respectively. However, -geometry 800x600-20-20, instead of placing
the window such that its bottom and right edges are at a distance
of 20 pixels from the corresponding screen edges, places the
window such that its left and top borders are out of the screen.
This is corrected by this commit, which also addresses the fact
that Qt5 does not define Q_WS_WIN anymore.
