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>
I introduced a regression in c14b9e67 for pasting images:
If an image is on the clipboard both as PNG and HTML with just an url,
but no plain text, pasting would fail. The reason for this was that
text contents was detected (the HTML code), nd preferred, but actually
pasting it resulted in an empty string, since the HTML import could not
handle the url This error was not checked.
The solution is first to try text paste if both text and image content
is present, and then try image paste if the text failed.
The main part of the fix (unicodesymbols) is from Jürgen. This commit fixes
tree problems:
- \; etc. were also used in text mode, but are math only
- all of those glyphs need to be forced with utf8
- actually, \; etc. are not the correct macros, since the encoded spaces are
breakable, but the math spaces are all protected. The sapce symbols are not
defined in the utf8 encodings.
When calling the default converter (convert) we pass the format on the
command line. In LyX we have various pdf, pdf2, pdf3, etc. formats all
representing PDF. We need to strip to trailing digit in the format string
otherwise the format is not understood by convert.
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.
In [19024f72\lyxgit] this line was removed. Later this caused that floats were converted to strings using ','s instead of '.'s. Readding this line fixes this.
The path to the lyx binary is either <build_dir>/bin (CMake) or
<build_dir>/src (autotools). This means the po directory can be found one
directory up.
Since 00387b2a38 it is possible to construct a dummy Messages object
which does not translate at all. With the old gettext implementation, a
Messages object without a defined language would have used a language from
an environment variable. Therefore, the duplicate definition of _() is no
longer needed. This gettext removal was really a good idea!
This is done by handling explicitly a dummy Message object, where no parsing of mo file is attempted. This avoids in turn that the lyxerr object is used during initialization of a global dummy Message object.
With gettext, we have been forced to install .mo files at the right place in order to read them. Now that we have our code, the situation changes.
* Add new method Package::messages_file(code), when returns the right path, depending on whether we are running in place.
* In Messages class use that intead of the existing one.
Get the default language by a mix of QLocale and LyXRC::gui_language
Known limitations:
* encoding is supposed to be UTF-8 (the charset parameter is checked);
* context is not handled (implemented differently in LyX);
* plural forms not implemented (not used for now in LyX);.
* tThe byte endianness of the machine on which the .mo file have been
built is expected to be the same as the one of the machine where this
code is run.
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'.
(unless it's already there, in which case it should move to the end of the next paragraph).
Change the preference setting name (mac_like_word_movement to mac_like_cursor_movement)
to better reflect its function.
Patch and description from Bennett Helm
- InsetBox.cpp:
a framebox without inner box and without a width is \fbox
a framebox with inner box is also \fbox
a framebox without inner box and with width is \framebox
- GuiBox.cpp: the width checkbox must be checked if there is width
- this was forgotten to commit;
(without this we would get invalid LaTeX code when changing in the box dialog a makebox without a width to a minipage and press apply - a makebox required to specify a width, at least an invisible one like "0cm")
* 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.
If there is a new toolbar, it will not be restored by Qt and we need to
initialize it ourselves. However, it is not so easy to find out which
toolbars are restored by Qt and which are not. For this, the setVisible
function of GuiToolbar is 'misused'. If the visibility is set, the toolbar
must have been restored by Qt and we should leave it alone.
LyX uses QTemporaryFile to create a unique temporary directory. This
temporary directory will consist of two random characters and the process
identifier (PID).
Currently, the two random characters are often the same because Qt's
random generator was not seeded. If there are a lot of lyx temporary
directories accumulated, the chance of failing to find a unique temporary
directory is (N/100)%.
The temporary directories can be left behind if either LyX crashes, or
when a file in the temporary directory is opened in another viewer when
LyX closes. This can be a pdf that is viewed in a reader that disallows
the file to be removed while viewing it.
InsetInfos of the type ICON have a graphics Inset in their paragraph.
These insets were inserted without a font. This lead to an assertion in
Paragraph::fontSpan because the fontlist_ of the paragraph is empty.
Move the cursor in front of a bibitem and press enter.
Paragraph::fixBiblio will insert a new bibitem without a font in the new
paragraph. This will make Paragraph::fontSpan assert because the fontlist_
of the new paragraph is empty.
Using "Font no_font" in case no font was supplied was wrong. Instantiating a font object without specifying the language lead to a font object having the default_language that is hardcoded to "english". See Language::read().
This caused that there were spurious language changes in the LaTeX output
and made some document uncompilable.
This reverts commit 3619954590.
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.
1.) Do not include layout tests on MAC, since the
linker-option which allows multiple definitions is
no longer supported.
2.) Indenting made consistent
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.
Previously, an empty paragraph would always yield something like:
<div><a id='magicparid-35' /></div>
because we had no way to "defer" the anchor tag. Now this is wrapped
into the div, in effect, and we abandon it all if there's no content.
Reason for this 'cleanup' is the strange "optional = false" lines at the
end of the "case md_item" and "case md_subitem". Then, it is nicer to
directly use the value of the switch to be the running variable and to use
this to determine whether an item is optional and whether we should quit.
The panels in GuiDocument and GuiPrefs are stored in a map. The keys are
the translated descriptions of these panels. Whenever someone changes the
gui language and reopens the Document Settings pane, LyX asserted because
it could not find the "Child Documents" pane.
In commit bd9e8fecd the currentIndex of the FindAndReplaceAdv Pane was
changed from 0 to 1. Since then LyX crashed when requesting the pane or
when changing LyX preferences.
This patch reverts this, although it is not clear why it would crash
otherwise. It is still committed like this, because LyX is unusable
without.
View Source pane layout now automatically switches between horizontal
and vertical design when docked in vertical or horizontal way.
Original idea and patch from Edwin.

Note: the long standing-fight with too bulky minimal QTextEdit size
is now solved via ViewSourceUi.sizePolicy=Ignored.
This is mostly unused private class members.
There are also a few unused functions that got #if'ed out. I never know in this case whether the code should be nuked.
False positive rate of hints is quite high. Although the includes can be
technically removed (due to other includes) they logically belong to the
header.
* report results in milliseconds instead of microseconds
* report total time spent in block, additionally to mean time
* cause compilation error with --enable-stdlib-debug
Move the handling of branch-(de)activate(master) to Buffer. This code was moved to Bufferview in [3a03e71c/lyxgit] because a cursor was necessary to call Undo::recordUndoFullDocument(). However, it turns out that the undo code is already prepared to handle an empty cursor (and do nothing in this case).
Therefore we do that and move the branch code to Buffer where it belongs.
Note that there was a bug in the previous code that broke undo support: recordUndo should always be called _before_ doing any change.
An iterator is typicall incremented passed the valid data into the 'end'
state. However, if this means that other functions are called with invalid
parameter, we should fix this.
This explains why fontSpan was called with pos==size() while this was not
expected to happen.
This patch reverts partly f5ad0c128a (Jean-Marc Lasgouttes; Get rid of
annoying warning message).
each failure.
There are several places I was not sure what to do. These are marked
by comments beginning "LASSERT:" so they can be found easily. At the
moment, they are at:
Author.cpp:105: // LASSERT: What should we do here?
Author.cpp:121: // LASSERT: What should we do here?

The default sizeAdjustPolicy is AdjustToContentsOnFirstShow. As the
combobox is initially filled with all items, it will not change size if we
later remove the 'At Decimal Separator' item.
Using Cursor::setCursor or even BufferView::setCursor is often a bad
idea since it does not run DEPM. In this case (and other cases in
f&replace code) it is better to use BufferView::mouseSetCursor (which
should maybe be renamed...).
Before, if a user had "Group" checked in GuiRef and double-clicked
on a category, that category would be inserted as a (broken)
reference. Now, when a category is double-clicked, nothing happens.
If a label starts with ':' and 'Group' is checked,
the label is now shown under "<No prefix>" instead of
not shown.
Note that labels starting with ':' can be valid in LaTeX.
If "Group" is checked, "<No prefix>" is shown only if there exists a
label with no prefix. Before, it was shown even when it was empty and
even when there were no labels at all.
This was a simple logic error that crept in during refactoring:
If the format does not match, and the converted file has been read,
the string must not be read.
This speeds up the copying, and although not many applications understand
MathML currently (MS word is supposed to understand it), their number should
go up in the future.
When using CMake, the binary files are stored in <build-dir>/bin. LyX can't fin tex2lyx with the current code. So, we have to point configure.py to explicitly look in the binary dir.
As discussed on the list. No automatic contents detection is done, the user
needs to use the special paste menu instead. I used the new TempFile class
for safe temporary file handling.
The documentation would go into section 2.2 of UserGuide.lyx, but I am not
allowed to edit that document.
FileName::tempName() is not thread safe, since the QTemporaryFile object is
immediately deleted after creating it. Therefore, another thread could create
the same temporary file in the time span before the user of FileName::tempName()
recreates it. This is not as theoretical as it may look: I observed that
repeated creation and deletion of QTemporaryFile objects always use the same
name.
This problem is solved by the new class TempFile which should be used like
QTemporaryFile itself.
dummy is the name given in the latex backend to simple (usually single) paragraphs and since dummy is not a docbook element it is acceptable to ignore it. It is a reasonal compromise.
The HTML export is now mature enough so that it can be used to transfer
formatted text to the clipboard. This enhances interoperability e.g. with
office applications.
This reverts a small part of 0526eb9d and gets rid of the double calls of
SVN::findFile() and GIT::findFile(). Please note that git detection does
currently not work because of 26dd4d0c.
When using 'find' and a string is not found, this is not an error or a
surprising event. It is often expected (e.g. after searching through
the whole document for a certain string eventually you will get this
message). The exclamation mark should be reserved for messages that
are unexpected or that need extra attention, such as errors.
Since a complete solution requires some refactoring, I fixed the bug for the
most important case: The main document language is only supported by
polyglossia. If any other language than the main one is only supported by
polyglossia the bug is still there.
This will be needed for layout forward compatibility, and could also be used
for a layout editor. Writing was only implemented for styles, not for complete
layout files (text class). I rarely made use of default values for missing
variables which exist in read(), so the output it a bit verbose (but more safe
against future changes). Also, some things like CopyStyle are never written for
obvious reasons.
This is a second attempt to fix the problem described in
6df4a7bb (2c2c1767 reverted the first attempt).
The solution here is more general: if we get to a certain point
in the code and there is no filename, an error is given.
The following command now gives an error:
lyx -e pdf2
And the following command continues to not give an error:
lyx myfile.lyx -e pdf
Before, the following commands correctly exited with code 1, but now
a reason for exiting is also given:
lyx -e pdf2 doesNotExist
lyx doesNotExist -e pdf2
This reverts commit 6df4a7bb40.
As Vincent points out, this commit is not correct. For one reason,
it would incorrectly exit with error for the following syntax:
lyx myfile.lyx -e pdf
I will look for a correct solution to the problem specified in the
message of the reverted commit.
Before, 'lyx -e pdf2' would give no error and would exit with 0. A use
case is if a user has in a bash script the following command:
lyx -e pdf2 "${mylxyfile}" || exit 1
where 'lyx' is mispelled as 'lxy' and thus yields an empty
string. If LyX does not exit with an error, the script continues where
the user probably intends for it to stop.
output, due to failure to clean the ids in the new citation stuff.
I've solved this by allowing the citation format information to contain
keys of the form "clean:key". This signals that we are to apply the
html::cleanAttr() function to the key before returning it. I.e., we
strip non-alphanumeric stuff, basically.
We only need to sort the formats when it is really necessary, i.e. for GUI
purposes.
This also prevents 11000 requests for translation everytime the toolbars
are updated.
The use of this profiler is trivial:
* #include <support/pmprof.h>
* in the block one wants to profile, add
PROFILE_THIS_BLOCK(some_identifier)
* At the end of the execution, statistics will be sent to standard error.
- 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
Previously, the format used for included pdf files was the same as for
document export via ps2pdf. This caused unwanted conversion routes, e.g.
export via odt->pdf instead of dvi->ps->pdf.
I renamed the format for included graphics and not for exported documents,
since otherwise the command line syntax for export would change. This would
require more adaptions for the users, since with the chosen solution the
custom converters are almost always changed correctly in prefs2prefs(),
so that only custom external templates need manual adjustement.
Before, it was done on editingFinished(). The new behavior is more
intuitive because it is easier for the user to see how editing the box
is connected with enabling/disabling the other widgets. Before, the user
would not get instant feedback and would have to click away before the
connection is revealed. This new behavior is less efficient, however,
because checkEnabled() is called after every keystroke.
need the master buffer here, too: in looking up fonts during XHTML
output.
I'm half tempted to pass the master buffer to these routines, though
there are times, I think, when we want the actual buffer: e.g., when
looking up branches.
* 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.
work we do when calling plaintext() for the purpose of generating
material for the advanced search function.
Here again, not only were we parsing BibTeX files, since Julien's
(sensible) introduction of plaintext output for that inset, but we
were in fact writing (to disk) complete plaintext output for
included files every time we did such a search.
worth doing, as we were creating too much output for tooltips anyway.
But we need to ignore BibTeX insets altogether, as the collection of
the references, etc, is too slow.
so we can write a limited amount when using this for TOC and
tooltip output.
This should solve the problem with slowness that Kornel noticed,
which was caused by our trying to write an entire plaintext
bibliography every time we updated the TOC. We did that because
he had a bibliography inside a branch, and we use plaintext for
creating the tooltip that goes with the branch list.
Other related bugs were fixed along the way. E.g., it turns out
that, if someone had an InsetInclude inside a branch, then we would
have been writing a *plaintext file* for that inset every time we
updated the TOC. I wonder if some of the other reports of slowness
we have received might be due to this kind of issue?
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().
Somehow I overlooked that \sideset also supports nonscript arguments for
left and right. This is now fixed, although I do not like the toolbar names.
If somebody knows something better, please improve.
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
This default argument is inserted iff no inset argument is present. This is useful particularly for mandatory arguments that need to have a sensible default value.
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().
The toolbar image is the one Uwe attached to the bug report. Note that
\sideset works only for operators like \sum in the nucleus. LyX allows
any content, so you might get a LaTeX error. I don't know how to prevent
wrong content in the nucleus.
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().
The current code is not able to unset an environment variable, only to set it to an empty value. This patch refactors a bit the Message class and uses a new EnvChanger helper class that allows to change temporarily an environment variable and that is able to unset variables if needed.
The patch also adds new functions hasEnv and unsetEnv in environment.cpp.
Open issues:
* there may be systems where unsetenv is not available and putenv("name=") does not do the right thing;
* unsetenv may lead to leaks on some platforms.
* when using unsetenv, we may need to remove strings from the internal map that setEnv uses.
At this moment we do not allow comparison between arbitrary hashes,
but except GUI the code is ready.
Thanks to the powerful way of git addressing we could even ask
for comparisons like '-2 weeks back' if someone wants to play
with GuiCompareHistory.
Only the local index is considered, no remote repo. Also getting the revision
(aka commit hash) is missing. How push and pull could be integrated with the
LyX VCS interface needs to be discussed, but the implemented functionality was
quite straight forward.
The advantage of having this in LyX is the intelligent file name handling
of included files. Implementation as discussed on the list, but ensure also
that an attempt to use locked files fails.
This only move the code, but does not change the displayed labels.
Thus for numerical citation, the label is set to the cite number;
for author-year citation, the abbreviated list of authors is used
i.e. "Smith et al. 2001".
Eventually, we might want to make the label customizable, or get
it from BibTeX.
It is not possible to transport the different error/abort/success conditions
of a VCS checkin through a simple empty or nonempty string. Therefore it was
no wonder that the return values were used inconsistently for different VCS.
Now the log and return status are decoupled, and all VCS are handled
consistently. This is a prerequisite for proper locking detection of the
upcoming rename command.
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)
* some functionality is in new modules now
new header locations and library names: QtConcurrent and QtWidgets
* method setResizeMode is renamed to setSectionResizeMode
* deprecated QAbstractItemModel::reset() is dropped now
* platform specific code like QApplication::syncX() is not common anymore
* QString::fromAscii() is dropped now
* some QDesktopServices methods has been moved to QStandardPaths
I do not see where this is really useful (contrary to real plaintext). And it breaks spell checking with hunspell and 8bit disctionaries (part of bug #8526)
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.
This bug was reported against the ubuntu build:
https://bugs.launchpad.net/bugs/1100046
Additionally, some extra code for avoiding double undo entries has
been removed, since this is handled by grouped undo now.
This patch implements 'move row' and 'move column' features for tabular.
The purpose is to provide a useful behavior in tabular that is
consistent with PARAGRAPH_MOVE_UP and PARAGRAPH_MOVE_DOWN so that the
user can, for example, do alt-<up> to move a row up. Alternatively,
icons for these features are also added to the table toolbar and
context menu.
If there is any selection, the feature is disabled. This is consistent
with how PARAGRAPH_MOVE_UP works in other contexts. Additionally, 'move
row' is disabled if there is a multi-row in the current or target row;
and 'move column' is disabled if there is a multi-column in the current
or target column.
'move row' moves only the left and right borders of a cell along with
the row. Similarly, 'move column' moves only the the top and bottom
borders.
Implementing similar functionality for other insets, such as arrays and
array environments, is on my TODO list.
Reordering citations is one case where catching "Citation undefined
on page ..." doesn't catch the need for a bibtex rerun. This patch
ensures the proper ordering is obtained in pdf output without having
to resort to closing and reopening the LyX document.
Most images are generated by development/tools/generate_symbols_images.py, but
some were drawn manually. Now there is no image missing from the ones the
script can generate.
Some macros defined by wasysym.sty work only in text mode: They either
produce an error in math mode, or wrong output. These symbols are now marked
as text symbols, so that no \ensuremath is created for LaTeX export if they
appear inside \text{}, and the correct images are created.
What was previously accomplished by wrapCitation is now customizable in the
layout files. What we provide by default here corresponds roughly to the
LyX 2.0 behavior.
- achicago
- apacite
- apalike
- astron
- authordate
- chicago
- harvard
- mslapa
- named
This allows these citation packages can be Required by the document layout.
LyX handles the package ordering, loading any of these packages before natbib
when both are required by the document layout. For example, apacite can be
used with or without natbib.
The package achicago isn't compatible with natbib out-of-the-box,
but the following compatibility code makes it work:
\usepackage{achicago}
\let\achicagobib\thebibliography
\usepackage[authoryear]{natbib}
\let\thebibliography\achicagobib
\let\UnexpandableProtect\protect
\let\SCcite\astroncite
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.
These are all generated by development/tools/generate_symbols_images.py, the
only manual adjustments were renamings due to case sensitive file systems on
windows.
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.
stmaryrd.sty sets these symbols up as variable size math delimiters (i.e.
they may be used with \left and \right). Now LyX knows about that and offers
them in the delimiter dialog as well as single symbols.
Only the first paragraph in those sequences goes into the TOC, since the environment is merged.
This is needed to handle the forthcoming beamer environments properly in the outliner.
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.
While exporting from the command-line, theApp() doesn't exist.
The colors foreground and background are only needed when
previewing, so ignore this during buffer export.
This replaces the fix in 4285b0b3 (Tommaso Cucinotta, 10-12-2012).
In this case, we do not need to pull in Qt dependencies.
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).
Fix#4981:
If the first or last column is deleted, the borders are preserved.
Similarly for the last row, but not for the first row. Selections are
supported.
Based on a patch by Zahari Dimitrov.
Fix the following bug:
When in tabular, enter "ab" in a cell. Place the cursor before "b". Hold
shift and press <right>, then (still holding shift) <right> again. On
the second <right> nothing appears to happen.
Related to #1802.
Fix#4981:
In tabular if a vertical selection is made with the keyboard (e.g.
LFUN_UP_SELECT), the selection is drawn if there are two cells selected.
Previously, the selection would be drawn only if there were more than
two selected.
If you have a selection across cells in tabular, moving the cursor
vertically up or down (e.g. LFUN_UP) now removes the drawn selection.
Before, the selection was set to false but it was not repainted.
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.
We must group the content which should be changed in size wit a pair of braces because the LaTeX size commands are otherwise switches. We already do so for many case, but not for the case that a size command is inside another command. This patch adds now always a brace pair around the selected text which is the safest method.
Both cvs and svn are able to retrieve non-existing files from repository,
but this was only implemented for rcs. This is a prerequisite for the
planned move and copy VCV operations. I also improved error schecking and
used extractFromVC() also for files specified on the command line if they
do not exist (in GUI mode, it was already the case in non-GUI mode).
It did always point to the buffer's file name, so it is not needed and it was
not used in most cases anyway. Instead, ensure that owner_ is always set and
cannot be changed later.
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.
Next try to make it to work on APPLE (and maybe on WIN32)
a.) Create the needed data-dir at configure time
b.) Use different target names for executable and data created with them
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
buffer-forall only takes one parameter now, which is the LFUN to
dispatch on all non-hidden buffers. A hidden buffer is defined as being
internally open in LyX, but not visible in any window (view).
Thanks, JMarc.
Just some comments on the patch:
- The executable name has to match the information in Info.plist (development/MacOSX/Info.plist.in and CMakeLists.txt). The autoconf config/lyxinclude.m4 file has been modified to make it work with autotools.
- The process to build OS X bundle is to first add all the files to be included to the bundle when calling add_executable (src/CMakeLists.txt) and then by calling setting the source file property of each of these files (development/cmake/Install.cmake, l.14) so that the files are properly located into the bundle. This is also why Install.cmake has to be included two times in src/CMakeLists.txt (once to build the list of files, once to set the location of the list of files).
- in CMakeLists.txt there is a line
install(CODE "set(BU_CHMOD_BUNDLE_ITEMS 1)")
What it does is to fix the owner permissions within the bundle - this is necessary because some libraries are copied within the bundle and might be owned by root
- An empty qt.conf is included in the bundle so that QT does not try to link to other QT libraries (which will not be included in the bundle)
- In development/cmake/Install.cmake, some OS X specific files (*.sdef, qt.conf, *.icns) have to be included in the bundle

The obnoxious messages in Private::setFilter cover any message set by lyx::dispatch. The solution I chose is to return early when the filter is not changed.
If this makes sense, then the same optimization should be added to CategorizedCombo, IMO.
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.
A dummy getGuiMessages function was missing. Instead of adding it everywhere, a new file is created that contains all the dummy functions needed by the tests.
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.
This adds an optional 'set' argument to the language lfun and reintroduces toggling.
Additions by me reintroduce the possibility to reset to the document language via 'language reset' or just 'language'
This might encourage users to post this information when reporting bugs
and sometimes it's useful to be able to copy the paths of the Library
and User directories.
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 the WA is the last one showing a buffer, then the buffer may either be
closed or kept hidden, or the user is asked. The behaviour is controlled
by a new preference option.
For discussion, see http://comments.gmane.org/gmane.editors.lyx.devel/142638
With non-TeX fonts, you can select a 'Non-TeX Font Default' math font, which simply loads unicode-math without actually selecting a math font, this then uses the default math otf font, currently Latin Modern. Other fonts still need to be set manually in the preamble, via \setmathfont.
The implementation suppresses unneeded package requests from unicodesymbols, but the output still uses macros instead of full unicode (both is possible with unicode-math).
The whole thing is a proof of concept, and it needs to be tested. I have tested it with the math manual, which compiles and seems to display correctly if I remove some hardcoded package loadings. OTOH I have not much experience with math.
This addresses #7449 partly.
In 0aead96461 it was introduced that the toolbar popup menu buttons are not
initialized until they are being used (i.e. pressed at for the first
time). As a consequence, these buttons are always enabled on start. Now
that we have the sticky button for view and update, I'm now annoyed by
this every time I start LyX.
This addresses #6543 by adding an option to prevent fonts such as Palatino and Times to automatically adapt the math font (IOW it lets you load the text font only for a bunch of fonts where this is easily possible).
Furthermore it adds an interface to select a specific math font, which is defined in latexfonts. Currently, this is only euler (the only one I know), but if there are other math-only tex fonts, they can be added easily (but note that this changes the file format).
Non-TeX math fonts are not yet supported. Eventually, unicode-math support can use the existing UI, but this is not on my agenda.
The LaTeX font now do not specify simply alternative packages or packages for OT1 encoding etc., but they refer to complete AltFonts (which are not directly accessible via the GUI). This way, alternative fonts can also have options (osf, sc etc.), and they can use all sorts of initializing methods (\usepackage, \setrmfamily etc.).
This assures that refs to existing labels are not being touched if a new label with a duplicate name is created, and the name then changed by the duplicate checker.
Branch candidate.
Fix thinko in Undo::endUndoGroup.
Do not reset undo groups in Undo::clean
The underlying problem remains: the various VC functions should not
always reload the buffer or at least should use the parameter
clearUndo=false.
Filenames embraced in <...> can occur anywhere on the line and multiple times. This fixes for me the case that graphics included via ERT were not tracked. It probably also fixes#8336.
This is a candidate for branch.
GuiTabular.cpp: a cell can either be a multicolumn or multirow, not both the same time, this is already respected by the toolbar and context menu, only the dialog allowed to set this although this was correctly never applied
should also go to branch
The stderr message "Object::disconnect: Unexpected null parameter"
often appeared when closing and opening buffers.
GuiView::on_currentWorkAreaChanged should not pass a null pointer
to Object::disconnect.
Fixes 2 issues:
1. LyX uses for a decimal alignment a multicolumn and having for a cell a multicolumn _and_ a multirow is invalid LaTeX.
2. It was impossible to unset a decimal alignment via the context menu or toolbar button.
The previous scheme of loading all possible translations and checking
whether the work is a bit too much "brute force" and causes problems
on Mac OS X (documents loaded with the wrong language).
Now there is an helper static method in Messages class that checks
whether a readable .mo file exist for the language. There should be an
API in gettext for doing that, but alas it is not possible.
As a consequence the method Language::translated() has been removed,
along with its cache.
This is the same protection used for \cite{}. Although "ulem" commands
don't strictly need this protection with \ref{} and friends, this helps
when one wants to use another package souch as "soul".
Indeed, ulem's \uline{} doesn't hyphenate words, while soul's \ul{} does,
and thus the output is much nicer.
With this patch, replacing ulem with soul is as simple as adding
\usepackage{soul}
\renewcommand{\uline}[1]{\ul{#1}}
to the preamble, without worrying about manually enclosing in \mbox the
\ref commands. In any case, the output from ulem remains unchanged.
Another possibility offered by soul is that of typesetting as
"yellow highlighted" the underlined text. This is achieved by adding
\usepackage{color,soul}
\renewcommand{\uline}[1]{\hl{#1}}
to the preamble.
The mhchem package treats the caret both as a shorthand for \uparrow or
as a superscript operator according to whether it is surrounded by
spaces or not. The \ce and \cf insets allow inserting spaces but there
is no provision for inserting a space after the caret, which is always
considered by LyX as a superscript operator. The solution here is to
insert a space after the caret if the superscript is empty or an empty
brace inset.
Mathed does not allow empty superscripts, so an empty brace has to be
inserted when working in LyX. On the other hand, when importing latex
code, an empty superscript is retained.
This has no effect whatsoever for normal latex code, as a space after
the caret is ignored. In any case, the output is only changed if an
empty brace inset is used as superscript. Specifically, the output is
changed from "^{{}}" to "^ {}".
The code in DocIterator::sanitize now follows more closely the
previous StableDocIterator::asDocIterator code. In particular, it adds
the slices one by one, since fixIfBroken will chop the cursor
otherwise.
In order to interact with native osx applications, AppleScript support is a plus.
Here is a patch that makes LyX respond to a simple command (run) and that allows to communicate with LyX as with the LyX client.
Example of use:
tell application "LyX" to run "server-get-filename" with argument ""'
returns
message:/Users/bpiwowar/newfile1.lyx, code:0
with a message and the error code
This bug occur only at certain Qt versions and systems and we do
not really understand what is going on.
Quoting Stephan - the parent path of "." e.g. never should be ".".
The inconsistency between the name of FileName and the internal QFileInfo
state looks very dangerous.
The LaTeX font information are now centralized and outsourced. This removes a lot of hardcoding and duplication and makes it easier to support new LaTeX fonts.
Normally, we do not load babel when English is the only language. However, if we check if babel is used from Font::validate, we need to surpass this test, else no secondary language is registered if English is the main language.
The forward flag is used to place the cursor behind the replaced text if it's true.
But it's not correct to move the cursor if it's false. The cursor is in front of the
replacement already after the replaceSelectionWithString() was done.
* Assure that really no language package is called when none is selected.
* Only call global custom package if global is desired.
This is a candidate for branch as well.
The previous scheme of loading all possible translations and checking whether the work
is a bit too much "brute force" and causes problems on Mac OS X (documents loaded
with the wrong language).
In the new scheme, autotools install a file lib/installed_translations that contains a list of installed languages (the .gmo files that got installed). This file is read
in Languages::readInstalledTranslations and allows to set the translated() property
of each language.
Fixes bug #7111: Assertion with undo and InsetBibitem
* add Paragraph::brokenBiblio(), with tells whether there is something to fix.
* rename Paragraph::checkBiblio to fixBiblio; simplify it greatly by using
InsetList methods
* In TextMetrics::redoParagraph, call recordUndo before fixBiblio (only when
there is something to fix obviously)
Special care is taken to update cursor only when it makes sense. Note
that there are cases where undo information is not recorded (current
cursor not in the slice where action happens)
Babel settings might contain @ characters. Check for this and wrap the settings into \makeatletter ... \makeatother switches if necessary (see discussion at #8265).
The code does a reload on the buffer to avoid loose pointers if the
file changes directory. This commit adds a bool parameter to
Buffer::reload to allow for keeping the undo stack intact. This is of
couse only wanted in this case, not when reloading an earlier version
of the file.
In the existing code for setting layout of pragraph parameters,
Text::undoSpan is used to "guess" which paragraphs should be saved in Undo.
With this patch the approach is more precise: before every explicit change
to a paragraph, a Cursor::recordUndo call is inserted. This is much more robust than trying to guess.
In particular, we do not look at depth changes at all, since they are now
handled in updateBuffer since #8159 has been fixed.
The goal here is to get rid of the old code that modified variables
LANGUAGE and LC_ALL, therefore creating the problems mentionned
in the ticket.
In the new system, there is no explicit "GUI" message handler, that
needs to be reset at each language change. Instead, getGuiMessages
calls getMessages with the correct parameter. This allows to simplify
greatly the code and to remove a lot of old cruft.
This commit does a bit more than fix selection, since it saves the full cursor state
in the undo stack. This means that undo now restores:
* the selection
* the current font
* transient mark (shall we keep this one?), logical position...
In order to do that, it introduces an intermediate class between Cursor and DotIterator: CursorData.
The new inheritance diagram is thus
DocIteraator -> CursorData -> Cursor
CursorData contains all the members of Cursor that define the current position, but not the stuff
related to current view of dispatch mechanism. It may make sense in the future to move members
between CursorData and Cursor and to move some member functions to CursorData.
Now UndoElement uses CursorData for cur_before and cur_after, but not for the cell. The undo API uses
also CursorData instead of DocIterator.
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
- Preamble.cpp/:
- move list definition out of anon namespace
- declare lists and a function in the class
- text.cpp: remove the now already defined list
If someone can tell me how I can tell QtCreator to actually use tabs, not spaces, I would be most grateful (yes, I have set Tab Policy to Tabs Only in Prefs)
- Parser.cpp: \verb can have any character as delimiter (except of ASCII letters) not only '+', therefore partly revert [3943b887/lyxgit] and fix it for all cases
The idea is to record undo at the place where the document is modified:
1/ in Buffer::updateBuffer, add a recordUndo, with the caveat that a
const_cast has to be used (because updateBuffer is const but
modifies the document, go figure).
2/ in GuiApplication::dispatch, add an extra undo group that
encompasses the updateBuffer call. Some other undo groups may be
redundant now, but it is not a problem since they do not cost
anything.
The button text of InsetInclude insets shows whether the child document is
included or excluded from compilation. Changing this for a child document
in the document settings does not get reflected on screen. This patch
updates the button text on the updateBuffer() call.
Preamble.cpp:
- support the font scaling
- improve coding style
text.cpp: - improve logic/coding style
XeTeX-polyglossia.tex:
- add scaling
- change document so that it is compilable using the Libertine font
Instead of adding the extra '\n' to tex2lyx, we should remove it from
BufferParams.cpp because it was introduced there unintendedly in d7eaaba9
(Juergen Spitzmueller; "support for CJK font argument"; Jun 5 2008).
This partly reverts commit c2810f922665c591a7c32d4c679e58e55132505a.
Fix commit [aa9fed93/lyxgit]: it is never a good idea to call substr(4) on a string without checking its length. Moreover, it is even better in this case to check that the first letters are "text" as the reminder of the code assumes...
- tex2lyx/Preamble.cpp/h: not all new header definitions since fileformat 413 have yet been added to texl2yx, so do it now; also change some new default values
- bugfix for the parsing of polyglossia's paragraph environments
- new support for polyglossia's language change commands \textxxx
- XeTeX-polyglossia.tex: add more testcases and add a missing \end
This allows to workaround the problem in #8198 - on some systems
we get dead caron as a single character instead of whole combined
character. I suppose this has rather something to do with X settings
than LyX per se.
