The algorithm used for breaking a paragraph in LaTeX export is changed
for avoiding spurious blank lines causing too much vertical space.
This change is tied to the introduction of a new inset (with two
different specializations) helping in either outputing LaTeX paragraph
breaks or separating environments in LyX. Both of the above goals were
previously achieved by the ---Separator--- layout and can now be
accomplished by the new inset in a more natural way. As an example,
after leaving an environment by hitting the Return key for two times,
a third return automatically inserts a parbreak inset, which is
equivalent to the old separator layout, i.e., it also introduces a
blank line in the output. If this blank line is not wanted, the
parbreak separator can be changed to a plain separator by a right
click of the mouse. Of course, an environment can still be separated
by the following one by using the Alt+P+Return shortcut (or the
corresponding menu key), but now the plain separator inset is used
instead of the old separator layout, such that no blank line occurs in
the LaTeX output.
Old documents are converted such that the LaTeX output remains unchanged.
As a result of this conversion, the old separator layout is replaced by
the new parbreak inset, which may also appear in places where the old
algorithm was introducing blank lines while the new one is not.
Note that not all blank lines were actually affecting the LaTeX output,
because a blank line is simply ignored by the TeX engine when it occurs
in the so called "vertical mode" (e.g., after an alignment environment).
The old ---Separator--- layout is now gone and old layout files using it
are also automatically converted.
Round trip conversions between old and new format should leave a document
unchanged. This means that the new behavior about paragraph breaking is
not "carried back" to the old format. Indeed, this would need introducing
special LaTeX commands in ERT that would accumulate in roundtrip
conversions, horribly cluttering the document. So, when converting a
modified document to old formats, the LaTeX output may slightly differ in
vertical spacing if the document is processed by an old version of LyX.
In other words, forward compatibility is guaranteed, but not backwards.
In C++98 std::istream does not use an operator bool(), but an operator
void*() instead, which prevents some unwanted conversions (this is one
possible implementation of the safe bool idiom).
In C++11 std::istream uses explicit operator bool, which prevents the unwanted
conversions using a new language feature.
This change does not have any effect on correct code, but prevents some
mistakes.
* remove unused class TexStream.
* remove unused virtual method Inset::cellXOffset
* remove second argument of FileDialog constructor, which was actually
not used
* remove some dead local code
* remove some unused private members of classes
* in InsetMathNest::updateBuffer, fix the logic of a test
This patch improves the cmake bundling process:
- reworked bundle handling for OS X: only when installing resources are copied, otherwise
only the smallest bundle is built
- on OS X, the utility programs (tex2lyx) are now installed in the right location
- it removes some unneeded BUNDLE DESTINATION
- it provides a basic support for QT plugins inclusion
- it properly builds a disk image on OS X (only the background image is missing)
- it fixes the library paths for all executables (not only LyX)
- Use the COPYING file for cmake install license
writer2latex surrounds quotes by braces which we skip to avoid useless ERT.
I broke this in 25fe87e5 which made Parser::next_next_token() not recognize
that it needed to parse one more token. If we had a unit test for the Parser
class it would probably have detected that. Now we have at least a test for
the special quote.
If we call tex2lyx on a temporary file created from the clipboard, the
file is always in utf8 encoding, without any temporary changes, even if it
contains encoding changing LaTeX commands. Therefore, we must tell tex2lyx
to use a fixed utf8 encoding for the whole file, and this is done using the
new latexclipboard format. Previously, tex2lyx thought the encoding was
latin1.
As a side effect, the -e option is now also documented in the man page.
The tests are now more robust if ctest uses '-j' (number of threads) parameter.
a.) keytests are running in sequence and in one thread only, no other thread running
b.) tex2lyx tests are locking in respect to each other
c.) Test gets one or more labels, so that we can select
ctest -L url
to run tests labeled url
d.) New macro settestlabel() to add labels to a test
When comparing the contents of two lyx-files, we should not care about the specific version. Later, this can be extended to also not care whether the file is produced by tex2lyx, lyx2lyx, or LyX.
Modified-By: Vincent van Ravesteijn <vfr@lyx.org>
LyX, lyx2lyx and tex2lyx produce now all the same version indicator consisting
only of the major and minor version. It is not decided yet whether future
development versions will add a -dev suffix, but for 2.1.0 this change fixes
the inconsistencies.
Unfortunately automake does not support file names with spaces for files in
EXTRA_DIST: These file names are put into a shell list, and it is impossible
quote the name in a way that works both with the shell and with make.
Therefore I removed the corresponding test file.
In roundtrip mode, tex2lyx produces documents with extension lyx.lyx, so that
the original files are not overwritten on re-export. This was not done for
included documents which were converted, and this broke 'make dist'.
* InsetBox and GuiBox: Use proper empty length instead of the broken -9.99col% trick
* some slight changes to the logic of GuiBox to make sure that values are set as needed.
* lengthToWidget(): handle properly the empty length case. All the other related Qt helpers did it already, it was probably an oversight. Also set the default_unit parameter as optional (not needed in this patch actually, but I got carried away :)
* allow generating LaTeX code for an empty length, since some broken code does that.
The default citation capability of LaTeX is not a true numerical
citation engine, rather it uses a mixture of labels/numbers. Thus
we now distinguish them: "numerical" always increments the bibitem
counter and uses its value as a numerical citation label, while
"default" only uses the bibitem counter when no label is provided.
LyX file format incremented to 471.
These should be used if any new style needs to be introduced in the stable
2.1 series: If the ForceLocal flag of the style is set, it will always be
written to the document header, so that even older 2.1 versions can read
and correctly output the document.
When running the test, you'll get the following messages:
Testing ../../src/../lib/layouts/siamltex.layout...
Layout.cpp (268): Cannot copy unknown style `Enumerate'
Testing ../../src/../lib/layouts/svglobal.layout...
Cannot delete style `Dedication'
Testing ../../src/../lib/layouts/svjog.layout...
Cannot delete style `Dedication'
Testing ../../src/../lib/layouts/svprobth.layout...
Cannot delete style `Dedication'
These are no errors of Layout::write(), but they indicate problems in the
definition of the layout files.
Kornel, it would be nice if you could do the cmake part.
- fileformat change
- it was a pity that LyX did not yet support a simple rectangular frame without a defined width but LyX did this for e.g. oval frames
- \fbox and \mbox often occur in TeX files and can now be imported
* Powerdot now also uses the native overlay item arguments
* a list option argument is finally available
* \pause natively supported (like in beamer)
* support for \onslide (via InsetFlex)
* support for \twocolumn
File format change.
With this commit, old beamer frames are converted to new ones. The old styles are removed (including the infamous \lyxframe).
This should be tested with as much beamer documents as possible (I have already done so), also, tex2lyx now probably produces invalid LyX files.
I added it because of a misunderstanding. If the encoding is really set too
late, to_utf8() in the Token constructor would probably fail, but a non-empty
putback buffer is no problem, since it was always created via to_utf8() ->
from_utf8().
This fixes bug #8554 and some recently introduced busg:
- Encodings::fromLaTeXCommand() can now handle all combining characters,
not only the one letter ones
- The remainder returned from Encodings::fromLaTeXCommand() must never be
thrown away in tex2lyx, but output as ERT
- No special case for combining diacritical marks needed anymore in parse_text()
- No special cases for accents and IPA combining diacritical marks needed
anymore in parse_text()
- special tipa short cuts may only be recognized if the tipa package is loaded
- Use requirements returned by Encodings::fromLaTeXCommand() instead of
hardcoded registering of tipa and tipax
- Get rid of the name2 variable in parse_text(): We must use name, otherwise
the extra stuff that might have been put into name vanishes
tex2lyx skips LyX preamble code only if it thinks that the file was created
by LyX (i.e. special comments are found). I don't like that, but this is
how it works and therefore the special comment neds to be added if the
theorem commands are to be skipped. This header makes also the temporary
setting of in_lyx_preamble obsolete, which caused skipping of user preamble
commands, which were not re-added by LyX.
- Convert prettyref to the autopackage mechanism
- Do not load refstyle automatically if some refstyle preamble code of LyX
is found, since LyX will only load the package if an actual reference
command is used. This is needed for mixed refstyle/prettyref documents.
- Only recognize refstyle commands if refstyle was detected in the preamble
- Only recognize prettyref commands if prettyref was detected in the preamble
- Add a mixed refstyle/prettyref test case
* use verbatimStuff for parsing chunks and make try to follow closely the sweave sytax constraints.
* merge the two cases for parsing << (noweb or quote)
* \verb|ff| requires that its parameter is on a single line.
- support for Cyrillic characters
- support for \textifsymbol and \ascii (fixes bug #8556)
- support for \ding
- tex2lyx/text.cpp: correct an indentation and use "name2" because "name" is already defined in this clause
- for all TIPA characters the tipa and tipx package must always be registered because these characters are also allowed outside a TIPA inset
- include \textvertline because we again reached the maximum number of if statements allowed by MSCV (so safe at least one for now)
The LyX file format only supports one CJK font mapping per document.
Therefore all CJK environments which use a different mapping than the main
one are output in ERT. THis is now explained in the test case, and also the
converion to ERT is improved (although it is still wrong e.g. for paragraphs).
- support for \textdoublevertline, \textvertline, \textglobfall
- support \!o and \!b and \!d and \!g and \!G and \!j
- support and \*k and \*r and \*t and \*w
- register the package "tipa" if \textipa is detected in an equation
- add a \textipa equation to the testfile
(I failed to implement support for the TIPA character "\t*{ }" and the command "\=*".)
- Use the LyX name of encodings instead of the LaTeX names.
The LyX name must be unique, while the name used by LaTeX
not necessarily, e.g. different packages might implement
support for the same encoding.
- Rename koi8 to koi8-r, so that the LyX and LaTeX names match.
- Rename euc-jp-plain to euc-jp-platex, jis-plain to jis-platex
and shift-jis-plain to shift-jis-platex.
- Add utf8-platex encoding (fixes#8408).
LyX file format incremented to 463.
- support for the combining diacritical marks
- support for \texttoptiebar and \textbottomtiebar
- test-insets.lyx: add complete testcase
- TODO.txt: update what still needs to be done
This is achieved by not calling Parse::tokenize_one() anymore in
Parser::good(): The status of the input can be tested without performing the
actual tokenizing. Now there are only two methods that may prevent an encoding
change:next_token() and next_next_token().
This is an addendum to [72a44b3c/lyxgit] because depending on the environment, LyX adds a \phantomsection before \addcontentsline.
- also update the test file
This is an important part of the tests. If updating the test cases is really a
problem there are two better solutions than not testing the format: Convert
the references with lyx2lyx on the fly, or remove the hard coupling of tex2lyx
and LyX versions again. Both increase additional possible error sources, but
these errors could at least be detected. If the test machinery is made blind
for versions, file format errors are impossible to detect.
Jean-Marc discovered a possible data loss caused by Parser::getChar().
This is now fixed, and Parser::getChar() is removed, since it is no longer
needed and easy to use it in the wrong way.
- nothing needs to be done for feyn.sty - it is already recognized as simple feature and the roundtrip using the feynman example file works
- update entry for undertilde to be uniform
When switching catcodes (for example to verbatim), there are in general some tokens that have already been parsed according to the old catcodes. It is therefore needed to "forget" those token and reparse them.
The basic idea is to use idocstream::putback() to feed the characters back to the stream, but this does not work (probably because we disable buffering). Therefore, we implement a simple stream-like class that implements putback().
This is a refactoring commit, which may introduce minor regressions, but should go in the right direction.
* introduce Parser::verbatimEnvironment, which is a wrapper around verbatimStuff
* introduce output_ert, which inserts a string as ERT; this allows to factor out several code instances.
* rename handle_ert to output_ert_inset: this creates an inset and then calls output_ert
* remove handle_comment (use handle_ert instead)
* remove handle_backaspace (unused now)
* use the new methods in handle_listing
TODO:
* use for other verbatim-like cases (Sweave chunk, url...)
* maybe implement Parser::unparse to reparse tokens already parsed with the wrong catcodes (if needed)
- Implement catcode setting in Parser
- add a new Parser::verbatimStuff method that reads verbatim contents
- use this method to parse "verbatim" environment.
- use it to parse \verb too.
- rename Parser::verbatimEnvironment to ertEnvironment.
TODO:
- use for other verbatim-like cases (Sweave chunk, lstlisting...)
- factor out the function that outputs ERT (including line breaks)
- maybe implement Parser::unparse (if needed)
Provide functions for translating to the LyX name
of an encoding from either a LaTeX name or an Iconv
name, with the possibility to specify the package.
This is in anticipation of changing to use the LyX
name of the encoding in the .lyx file format and
allowing multiple lib/encodings entries to have
the same LaTeX name (but different packages!).
The tex2lyx parser needs to worry about the iconv
name of the input encoding, so store that instead
of the latex name.
The old layouts are still there (marked as deprecated). The new ones are more or less correctly reverted (polishment required), but the old ones not yet converted to the new. Once this is done, a further file format change should be made.
These encodings were not defined, since they must not be used as document
encodings (the characters {, } and \ may appear in high bytes, and latex
would be confused). However, they are supported by CJK.sty (which uses a
preprocessor to circumvent the limitations of the latex executable). These
encodings are now defined, but used for import in tex2lyx only.
The test case CJK.tex contained fake tests for shift-jis and big5 (the
japanese and chinese characters were entered using the utf8 encoding), and
therefore the wrong interpretation of these encoding looked as if it worked.
The comments about missing iconv support of shift-jis and big5 were wrong as
well (otherwise shift-jis-plain would not work either).
Actually, the test case showed several problems:
- ERT insets did use layout "Standard", not "Plain Layout"
- The font scale was read correctly, but tex2lyx claimed that it did ignore
the option "scaled=0.95"
- If a third argument of the CJK environment was given, it caused the whole
environment to be put in ERT with a broken encoding. This is now fixed for
the bug test case by using the \font_cjk header variable, but the encoding
problem still exists for unsupported encodings. I'll file a separate bug
for that.
- The CJKutf8 package was not handled in the preamble parsing. Therefore the
chinese comment in the preamble was read with a wrong encoding, and guessing
the document language did not work.
The new file CJKutf8.tex was created by copying and modifying CJK.tex, but
unfortunately it is impossible to tell git to inherit the history of CJK.tex
for the new file (search the web for git svn copy if you want to know details).
Special characters as created by latex_path() where not converted corectly
from LaTeX macros by tex2lyx. Now this is done, even for file names containing
double quotes which are not used for quoting spaces. These file names are not
legal on windows, and will causes probelms in DVI files, but if they occur
tex2lyx does not produce invalid .lyx files.
The fix is basically mechanical, the additional code for fraction like insets
with three arguments was stolen from \unitfrac. As any math package,
stackrel.sty needs a buffer parameter to switch it off.
I also added the two stackrel flavours to the toolbar.
Both problems where caused by the fact that tex2lyx did not handle
natbib/jurabib citations correctly if natbib/jurabib was loaded by the
document class. Therefore it tried to parse the standard \cite syntax, and
did not recognize \citet and \citep.
The \frametitle command is less convenient to use than the \frame argument, but it provides more options (overlay/action and short title). We thus provide this additionally to the option, like beamer itself does.
This has a list-like structure (with \onslide item commands). The previous implementation was rather useless, since it required lots of ERT. Since the new implementation is so different, we use ERT for conersion/reversion.
The lyx2lyx routines are not yet perfect, though.
The stmaryrd package adds support for lots of math symbols, using a font
designed to accompany the computer modern fonts. The changes in detail:
- Fix generate_symbols_list.py to work with stmaryrd.sty. It loooks like it
was automatically translated from a perl version and never used.
- Generate the new symbols in lib/symbols using generate_symbols_list.py and
add some manual adjustments
- Generate stmary10.ttf by a simple ttf export from stmary10.sfd with fontforge
- Add license info for stmary10.ttf
- Create a test file with all symbols from stmaryrd.sty. Actually it would be
nice to have this for the other fonts as well.
- The mechanics: lyx2lyx, tex2lyx, font machinery etc.
This patch puts all projects into subfolders (at least for MSVS). In this
way, there is a better overview (especially if the number of test projects
will be increasing).
Now that we have module support for literate programming, it is possible to do a noweb cleanup. This is basically a patch from Kayvan Sylvan:
- get rid of literate-xxx classes
- rename Scrap to Chunk, since this is the name noweb doc uses (Scrap is from nuweb)
- update lyx file format and add lyx2lyx support for gettting rid of literate-xxx classes
- update documentation
On the top of it, update tex2lyx to
- avoid creating files with literate-xxx class
- fix conflict between parsing << as a quote and parsing it as a Chunk
- create Chunk layouts instead of Scrap ones.
Actually tex2lyx can handle modules since some time (#5702), but not
theorems (#5776). Now the following issues are fixed:
- Modules that depend on other modules can be loaded, since the dependencies
are loaded first
- Default moduls of the text class are loaded correctly
- \newtheorem is recognized as a command that defines new environments and
treated similar to \newenvironment
With this new command line switch a list of modules can be loaded
unconditionally. This seems to be needed for the literate programming formats,
and it is useful to work around bug #5702 as well.
The listings inset does automatically load the color package if any parameter
contains \color. As mentioned in bug #8066 tex2lyx needs to be aware of this,
so the \usepckage{color} is automatically skipped in these cases.
Creating LYX_DATE dynamically at configure-time caused unwanted recompilation
of the whole directories (src + src/tex2lyx) because all the relevant objects
were dependent of a common file (flags.make in case of "Unix makefiles") which changed
accordingly.
There is now a new include (lyx_date.h, with only one definition)
Nothing changes for automake, since in this case LYX_DATE is defined in config.h
s is a valid horizontal position for framebox (as well as for makebox, which
was already parsed correctly). There was even a test case, but with a wrong
reference.
Instead of annoying the user with an automatically created note in the output
document which she needs to delete manually, determine the document language
automatically for documents that use CJK. This is done using a heuristic which
roughly counts the number of characters in each language and sets the one that
is used most often. This is not perfect, but it works for the two major use
cases: A document with only some CJK parts (in this case the babel language is
used), and a document which is mainly written in one CJK language. It is only
a minor problem if the heuristic is wrong, since the TeX export is still
correct, and there is no spell checking support for CJK anyway.
Now all regression tests do pass except for some relative path issues
depending on the location of the build directory.
The previous output was read correctly by LyX as well, but the new version is
more similar to the files written by LyX. Also update TODO with recent file
format changes.
Commit 7cfac95 got rid of empty lines that were created by removing \usepackage
statements. However, it added an additional newline in case the \usepackage
was not at the end of the line. This is now fixed.
The old fix was incomplete (\verb~\~ was translated to \verb~~ in roundtrip).
The real cause for this bug (and also the mistranslation of \href{...}{\}})
was the misbehaviour of Token::character() (see comment in Parser.h): This
method even returns a character if the category is catEscape, and this is not
wanted in most (all?) cases.
If this option is given, included files will be copied to the output directory.
Also -roundtrip is now allowed with given output file.
-copyfiles is useful if you want to ensure that no file (not even an included
one) is overwritten by a subsequent export from LyX. Both changes are needed
for unit tests that do not write to the source directory.
The input and output file names of tex2lyx may be relative. In this case,
getMasterFilePath() and getParentFilePath() return relative paths as well.
Now the file name translation logic for all kinds of included files can
cope with that.
If there was an encoding set by the inputenc package, it must not be ignored.
Now all tex2lyx test cases can be exported to .tex again by LyX (although
there are still some differences in the .lyx output).
It is invoked by 'make check' (automake only, it would be nice if someone
could add it to cmake as well), or by calling
python src/tex2lyx/test/runtests.py <path to tex2lyx binary>
by hand. Currently, it does not compare the output (this comes later).
The added .lyx files are from tex2lyx around mid of april, so that you
can see the regressions of the current version if you run the test
yourself (simply run git diff afterwards).
The home made test runner is quite stupid, but better than nothing.
Feel free to improve it or replace it with something better, as long
as running it stays as simple as now.
- tex2lyx/text.cpp:
- fix bug that swallowed valid braces
- the encoding is "Bg5" not "BIG5"
- add and update comments
- CJK.tex: add an example for the Bg5 encoding
