The horizontal alignment changes caused a regression for documents in older
formats. This could have been fixed by adding the following lines to the
format entry for 489 in development/FORMAT:
Previously, the horizontal position was ignored except for the
following parameter combinations:
- fixed width and type Boxed and without inner box
- fixed width and any type and with inner box and with makebox
Now, it is also used for the parameter combination below:
- makebox is not used and not (type Boxed and without inner box)
and a corresponding conversion to convert_BoxFeatures() in
lib/lyx2lyx/lyx_2_2.py. However, it was decided to revert the box alignment
changes instead: The box alignment can contradict the paragraph alignment. A
better way to avoid the additional space that can be created by paragraph
alignment (which was the motivation for implementing box alignment) is the
same as for table cells (see noTrivlistCentering() in src/Paragraph.cpp).
This would be a file format change and it is too late now for 2.2.0.
See http://www.mail-archive.com/lyx-devel@lists.lyx.org/msg188147.html for the
complete discussion (subject "Regression in lyx2lyx box alignment").
The correct mappings break the tex2lyx roundtrip tests because both,
the tests and tex2lyx use the wrong mapping (\b for "combining minus below").
Fix tex2lyx and the test files so that round-trip tests pass again.
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.
There are still a few warnings of the kind
(style) Variable 'x' is assigned a value that is never used.
since I did not touch code where I was not sure whether there might be a real
bug, and I kept some for symmetry reasons as well.
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.
As Günter found out running the tex2lyx tests overwrites the test references
if the build directory is identical to the source directory. Therefore the
tests would always pass, but git diff would show a non-empty diff if the tests
should have failed. Since it is better anyway to build in a separate directory
we simply do not support srcdir = builddir for the tests and abort with an
error.
This brings the external inset on par with the graphics insets as far as the
clipping option is concerned. The graphicxs package supports both: A bounding
box without units (which means that bp ia assumed), and a bounding box with
units, so we can simply output the values including the units.
Being able to compile document with zipped .eps files was a useful feature of
the graphicxs package 20 years ago, but the LyX support is no longer relevant:
- The flag is ignored if preview is on
- If pdflatex is used then uncompressing happens during the compilation anyway
- If set, the flag prevents LyX from issuing proper error messages if
something with the image is wrong
- For hard disk capacities from 20 years ago not uncompressing is a useful
feature, but for current hard disk capacities it does not matter
- The external inset does not have it, and if we want to merge both insets
one day we would need to implement it there, which is even more difficult
than in InsetGraphics
Unfortunately I overlooked in 44f73b0650 that the first three whitespace
changes in box-color-size-space-align.lyx.lyx were actually correct, so they
should not have been reverted. In detail:
1), 2): The space after \raggedleft must not be part of the ERT inset, but it
is ouput by check_space() as part of the standard text which follows.
3): The space in front of www is caused by the fact that there is a
newline between the opening brace of the parbox and the \centering
command, so this space is not the one after \centering (which is
correctly swallowed). This additional space is in fact not needed,
and the contents would look better in LyX without it, but since it is
not caused by special code I'll put it back in the refernce for now.
We can still improve this in the future if anybody has a good idea.
The remaining whitespace issues are all fixed by a simple change in
parse_text(): Instead of always eating whitespace after detecting \centering
et al, and always output a space as part of the ERT if these commands need an
ERT, let the standard space handling mechanism kick in: skip whitespace if
no ERT is used (in this case LyX will always output the needed space), and
do not touch whitespace if an ERT is used.
These should not have been done without discussion.
- Removal of the dcolumn table in 1a8b74f5e1. Even if LyX does not support
dcolumn anymore, it is still a useful test whether tex2lyx imports it
correctly.
- Removal of the first "%% LyX" line. A long time ago it was decided (after
long discussion between at least Jean-Marc, Uwe and me), that this line is
interpreted by tex2lyx, and used to remove some LyX-generated preamble code.
These lines in the current tests exist on purpose (one can see in the diff
how the removal added unwanted stuff). I do not really like the
interpretation of the "%% LyX" line, but if this behaviour is to be changed
then this needs discussion first.
- Changed comment of \date. The comment was put there on purpose, and the
warning which was "fixed" by the change hints at a limitation in LyX, not a
tex2lyx problem (LyX does not know that a comment inset between some title
insets is OK). The roundtrip .tex output was OK with the old version.
- Change of \verbatiminput{foo}. This was supposed to test whether a
verbatim inset is correctly created even if the included file does not
exist.
- Removal of \lyxlines. Although these tests test input of files created by
old LyX versions, they are useful.
- Change of the lemma in test-modules.tex. The old version was put there on
purpose, and the file itself explains why it is translated to ERT.
There is a general problem of tex2lyx handling theorems. it is not sufficient to cure only one instance as I did. For more info see bug #9561.
Update the references accordingly.
With the now removed command we said that this is a file created by LyX but this is not the case
- also replace a comment to avoid LaTeX warnings about mixing title and non-title stuff
before LyX 2.1 was released the dcolumn support was dropped and another method was used to align at the decimal point. Nevertheless the old LaTeX table was even wrong in terms of dcolumn
Now a table is used that uses the decimal alignment as it is supported by LyX
The idea is to get a compilable file that does not require programs that are only available on certain platforms.
For example on Windows there is no Gnumeric available (only a very outdated and unsupported version with bugs).
there were 2 issues:
- the body was not output to the Preamble
- the theorem module already defines a theorem. It must not be output to the preamble to avoid a redefinition error of LaTeX
update the test files accordingly
\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 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.
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.
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.
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.
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.
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.
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.
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.
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.
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 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.
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.
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.
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.
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__.
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 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.
This is a follow-up of bug #8967. The implementation is self-explaining, the
only part which needs a comment is lyx2lyx: Since a 100% correct solution is
not possible, it has been decided not to switch amsmath off in the forward
conversion if no other ams command than \smash[t] and \smash[b] is used, but
to consider it a bug that older versions do not load amsmath automatically for
these commands. In the backward direction it is easy to keep the document
compilable, so just do that.
