Old LyX version can cope with degenerated multicolumn cells spanning only one
column, so these should not cause a conversion of the whole formula to ERT.
Such columns are used to set border lines or alignment for single cells.
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.
I don't understand why the string "shadowsize" is not already in the file because when I convert from format 474 to 489 it is added. So why is it not there when I convert from format 474 to 491.
We also get a consistent look with amsmath, so require esint or amsmath.
When resolving alternatives, do also take into account whether the package
is available. For this to work, we also need to test for amsmath.sty (which
was surprisingly not yet done).
The "save-as" part of the bug is fixed by extending the \textclass tag
such that, if a local layout file is used, its path relative to the
document directory is now stored together with the name. If a relative
path cannot be used, an absolute one is used but, in this case, the
document is not usable on a different platform.
The "copy" part is fixed by introducing a new \origin tag, which is
written when the file is saved. This tag stores the absolute path of
the document directory. If the document is manually copied to a
different location, the local layout file is retrivied by using
\origin (which is only updated on save).
This new tag may prove useful also for locating other files when the
document is manually moved to a different directory.
As in the original implementation the files needed for the layout
(for example, a latex class) had to be in the same directory as the
layout file, this directory has also to be added to TEXINPUTS.
Avoid that \newcommand[x] definitions of math macros are pushed multiple
times to the preview loader.
Redefinitions (via \renewcommand[x]) are properly handled.
If use of hyperref is detected, the postscript route is not attempted
(because we know it will fail) and the PDF route is directly chosen.
Also account for all upper case extensions for pdflatex image files.
Was forgetting this last bit from 64e0c558. Also give a message such
that the user is informed that not everything is lost if latex fails.
With this, the previews are generated also when the document directly
specifies a specific pdf output format.
This is a followup commit to 691fdea3 and restores the behavior of the
script as it was intended before 64e0c558, other than taking into account
possible inclusion of files that only pdflatex can process and the
possibility of multiple defined math macros.
The instant previews in the math manual now work again.
- enrich the examples
- add info about naming
- formatting fixes to improve the layout of the PDF
- make the document compilable also if the package insdljs is not installed
If pdftocairo is detected, it is used for generating bitmaps in the
legacy method route in preference to ghostscript. This is justified
by the fact that the conversion is 4 to 5 times faster and the
quality of the generated images is superior.
When the dvipng route is selected and latex fails, the lyxpreview2bitmap.py
script simply bails out. The failure may be due to using a specific pdf
only feature in ERT (for example, the inclusion of a pdf image).
In this case the procedure may succeed simply trying to use pdflatex
and the legacy conversion method.
The \lightning symbol is text mode only. Hence, for using it in
mathed, it must be inserted in a text mode environment such as
\mbox, \text, etc. However, as it is not marked as textmode,
LyX "helpfully" encloses it in \ensuremath everytime one tries
to put it in a text mode environment, thus defying the countermeasure.
By declaring it textmode only, LyX stops doing that and thus it can be
correctly output by simply selecting it and hitting Ctrl-M.
Control + Shift + PgDn now moves a tab to the right.
Control + Shift + PgUp now moves a tab to the left.
These keybindings are consistent with Chromium, Firefox,
Nautilus, and gnome-terminal.
Note that I allow for wrapping. This is consistent with
allowing wrapping for buffer-{next,previous}, but there
might be reasons to disable it in the future.
This template was only reported as failing to compile by LyX as of
0a6120cb. I do not know how long this template was actually failing
to compile without error. The problem was that the class requires
\doi to be defined. This might not have been a requirement in
previous versions of the class.
Thanks to Enrico for finding the problem and solution.
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.
When closing a document with the cursor near an icon info inset, LyX
may crash on loading again the same document. This is most probably due
to the fact that compressed svg icons are first uncompressed to a
temporary file before being used. The temporary file is then deleted
but something still expects to find it in place. The exact circumstances
that lead to the crash are unknown, and maybe there is also a race entering
the picture here. However, a document that always leads to a crash can be
found attached here: http://article.gmane.org/gmane.editors.lyx.devel/154566
This commit does not fix the cause of the crash but rather avoids it.
As a bonus, the svg icons used by LyX are not uncompressed anymore before
being used, speeding up startup time. This is not a problem, because Qt
can deal with compressed svg images.
Imagemagick detects the inut file format based on contents. Therefore it does
not make sense that we prefix the to be converted file name with the extension
(assuming that the file extension matches the imagemagick format name). This
breaks formats where the extension used by LyX does not match the imagemagick
format name.
- Restore proportion between icons, such that, for example, \imath
is not confused with a lower case 'l' or \textdegree with \circ
- Use real \mathbb and \mathcal TeX icons
I'll revise also the other sets in the Math Panels toolbar along
these lines. It is important to see whether a symbol has ascendents
or descendents or what is their relative size.
- Use paths, not fonts. Have a look at the sqrt icon in the image attached
here http://thread.gmane.org/gmane.editors.lyx.devel/154179/focus=154183
to see what may happen when a font is not present on a given system.
- Make uniform the height of the parentheses.
- Move a couple of icons to the oxygen subdir (I was not sure it was Ok
replacing them. If yes, they can be simply deleted).
I did not notice that all icons in math/ are shared and in a0895046 I have
overwritten some of them. I am restoring them in the proper subdir.
Two of them, namely font.svgz and frac.svgz, give warnings that should
be addressed. Anyway, I see that these icons use fonts. They are better
substitued with paths (a menu entry in inkscape) because if the fonts
are missing on a system, the icons look different and, in general, they
may look ugly.
You have to manually delete the lib/images/svg directory as git
tracks only files.
There may be warnings on the terminal due to some faulty icons that have
to be found and corrected. Moreover, some of the icons are not rendered
too well at the default size. These ones should be properly tweaked.
Kudos to Jürgen for putting together such a large number of icons.
Most of the changes are related with dictionaries returning views instead of
lists.
xrange -> range (since xrange is gone in python 3)
The code that is special to support both python 2 and 3 is enclosed in a comment
\# Provide support for both python 2 and 3
and
\# End of code to support for both python 2 and 3
And so later it can be removed safely when python 2 is no longer supported.
We have some math macros that exist only because LyX can display them easily,
but which require user preamble code. These commands should not appear in
autocompletion, they are only there to make the formulas of users who actually
need thgese symbols and know what to put into the preamble more beautiful.
The svg files produced by vector editors may end up containing a lot
of unused elements that increase their size without any impact on
quality. For example, this occurs when copy/pasting between images
such that unused effects or shadings simply clutter the files.
Removing these elements in some cases may reduce the size to one half
or one third of the original one, leaving unmodified the image quality.
I also tweaked some existing icons to make them look better at default size.
Moreover, some text was replaced with paths, because the required font may
not exist on a system and font substitution would take place, making the
icons look different on different systems.
Both the hyphen and special phrase conversion did not exclude insets which
reference external files. This was wrong since LyX does not replace
\SpecialCharNoPassThru etc for these insets.
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.
Thanks to Scott for testing. Command insets do not use InsetText for the
arguments, so users have to write them in LaTeX syntax (this is bug #4595).
Therefore we must leave hyphens alone in these insets.
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.
I am also replacing some existing icons with reworked ones that
look better at small sizes. I think that these icons are now
comparable to the png ones as regards quality at the default size.
As discussed on the list, but I did not need to create two new pdf formats
since any given document either uses TeX fonts or not. For the same reason
I also added an additional converter to PDF (cropped).
Writing these policies down makes it easier for newcommers to
understand guidelines and the intuition behind them.
The two policies this commit adds were responses by Georg and Richard
to two threads on the mailing list. The policies are titled
"When to set a fixed milestone" and
"Can we add rc entries in stable branch?".
After the str-metrics merge, the kludge for displaying symbols whose
code point corresponds to a soft-hyphen was not working anymore.
The solution is replicating the offending glyphs with index 0x00ad
at a different index. They were replicated at 0x00ac, whose glyph
was missing in all affected fonts.
However, this would not work by alone because, if a system font with
same family name exists, it would be picked up instead of the right one
(at least on non-Windows platforms). For this reason, the style of the
fonts has been changed from "Regular" to "Lyx", so that we can discriminate
the right font. However, this requires using at least Qt 4.8. If an
older Qt is used *and* a system font with same family name is already
available, the affected glyphs will all turn out on screen as the
"logical not" symbol.
I have also set the executable flag on the font files, because on Windows
they are loaded only in this case.
This solves #9229.
* \caption does not need to be protected in general
* the contents of \caption arguments need to be protected, though.
All styles related to caoption inset have been audited and updated.
The special casing of captions in longtables has been removed, since there is no special case.
Fixes bug: #9177
This is a part of bug #9372. The remaining part (\ne) is not easy to fix,
since \ne is a predefined macro internally, so the HTML output is done for
the expanded macro, and we have no machinery to assign a HTML output to a
complete macro.
The reason being the backslashes in the path. Note that escaping
does not work here because the path is being interpreted multiple
times (how many times I don't know) and that would be fragile.
For this same reason, the change is not limited to Windows.
This allows to address two main issues
* \thanks does only accept one paragraph, while \footnote allows several (ticket #2666)
* footnotes in titling environments were not numbered on screen.
Moreover, the code reduces hardcoding of features, which is always a good thing.
There are several pieces in this commit:
* new numbering type \fnsymbol for counters
* the Foot inset changes its layoutName() to Foot:InTitle when inside a paragraph with InTitle property. This is set when running updateBuffer.
* Foot:intitle uses the \thanks command, does not allow multiple paragraphs and marks its contents as moving argument.
* The InsetLayouts for Foot now have properLaTeXName/Type, so that InsetFoot::latex can be removed; further code simplification is probably possible.
Fixes: #2666
C-M-a is bound to the global "select all". The
reason for this change is that selecting an inset
is a more common operation that selecting an entire
document.
This patch is the result of discussion on #7727.
This makes the script usable on windows and speeds it up by an order of
magnitude, since no new process needs to be forked for each layout file.
It also does not conevrt .old files again.
This is a patch I originally sent to lyx-devel in 2012 with subject
'Load footmisc.sty instead of using copied code from obsolete stblftnt.sty'.
It now takes all comments into account: It works also if the user loads the
package herself, it can be disabled by providing the footmisc feature in a
layout, and it does not use the ugly \AtBeginDocument{}.
Fix a crash reported in #7727. This happened because cur.pos() was reset before cur.pit(). In this case, cur.lastpos() will usually be wrong.
Fix bad behaviour when selecting at top level with several paragraphs.
Update documentation.
- the example was designed to follow the style of the other LyX documentation files, e.g. not to insert options as one big TeX-code inset.
- fix some typos
- (I cannot save files with LyX 2.2 atm due to bug #9234)
this module was not usable since the preamble stuff was missing and also almost all options. But many PDF-comment types are quite useless without options.
These are SVGs from the Tango icon set as well as some theme-independent self-made icons. Many icons are missing. This set s a wild mixture of Tango, old KDE icons and some self-made icons drawing on (to me) unknown models.
I leave the task to finish this set (and thus the SVG icons generally) to others.
These are automatically generated via the generate_symbols_svg script. Some were modified manually afterwards.
These certainly need some manual care, and a number of icons are missing (cannot be created automatically). But it is a start.
This reverts commit cde8707 and changes "AGUTeX" back to "agutex".
The maintainer has changed "AGUTeX.cls" back to "agutex.cls" and has
confirmed (through private email) that he plans to keep the filename
all lowercase now that he is aware of case-sensitive file systems.
This branch implements string-wise metrics computation. The goal is to
have both good metrics computation (and font with proper kerning and
ligatures) and better performance than what we have with
force_paint_single_char. Moreover there has been some code
factorization in TextMetrics, where the same row-breaking algorithm
was basically implemented 3 times.
Globally, the new code is a bit shorter than the existing one, and it
is much cleaner. There is still a lot of potential for code removal,
especially in the RowPainter, which should be rewritten to use the new
Row information.
The bugs fixed and caused by this branch are tracked at ticket #9003:
http://www.lyx.org/trac/ticket/9003
What is done:
* Make TextMetrics methods operate on Row objects: breakRow and
setRowHeight instead of rowBreakPoint and rowHeight.
* Change breakRow operation to operate at strings level to compute
metrics The list of elements is stored in the row object in visual
ordering, not logical. This will eventually allow to get rid of the
Bidi class.
* rename getColumnNearX to getPosNearX (and change code accordingly).
It does not make sense to return a position relative to the start of
row, since nobody needs this.
* Re-implement cursorX and getPosNearX using row elements.
* Get rid of lyxrc.force_paint_single_char. This was a workaround that
is not necessary anymore.
* Implement proper string metrics computation (with cache). Remove
useless workarounds which disable kerning and ligatures.
* Draw also RtL text string-wise. This speeds-up drawing.
* Do not cut strings at selection boundary in RowPainter. This avoids
ligature/kerning breaking in latin text, and bad rendering problems
in Arabic.
* Remove homebrew Arabic and Hebrew support from Encoding.cpp. We now
rely on Qt to do handle complex scripts.
* Get rid of LyXRC::rtl_support, which does not have a real use case.
* Fix display of [] and {} delimiters in Arabic scripts.
For Windows: AcroRd32 and gsview (both 32 and 64 bit versions).
For Unix: qpdfview.
Qpdfview is a nice alternative to Okular for KDE users and a superior
alternative to Evince for Gnome users, due to its complete synctex
support. It only depends on Qt libraries for the graphical interface.
This variable was introduced to guard against any bad consequence of the then-new right-to-left
languages support. Let's be bold and get rid of it altogether!
Now right to left support is always enabled.
The lyx2lyx conversion for format 352 was incomplete: It should have been
added the \use_indices setting, but it relied on the fact that the default in
LyX for missing \use_indices is the same as the old format without that
setting used. However, the default might change in the future, and later
lyx2lyx conversions rely on that setting as well.
Thanks to maciejr we know now what the remaining problem was with bug 7954:
My unicode symbol fallback works fine, the problem was that a font named
"Symbol" is available on OS X, but it does not use the font-specific encoding
we expect: Almost all glyphs are at their unicode code point.
Therefore the bug is fixed by re-enabling the unicode workaround and blocking
the Symbol font on OS X.
This is needed so that the new format number is actually used. Since the
conversion is a noop I did not update the layout files (more updates will
come).
trim_eol() assumes that a line always ends either with \n, \r, or \r\n.
This assumption is always valid except for the last line of a document, since it
may miss the trailing newline. LyX does not create such documents, bu they may
result from automatic creation tools, and LyX can read them, so lyx2lyx should
be able to read them as well.
This is mainly needed to reduce the amount of ERT if you convert AMS example
documents with tex2lyx. No GUI support is needed, since \notag is equivalent
to \nonumber.
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.
It currently does not make a difference that it is before
Adobe Reader in configure.py because as Enrico points out
on Windows the default viewer configured in the OS is used.
Beamer documents do not have a "--Separator--" layout but a
"Separator" one. Also fix a thinko causing the deletion of
"\end_layout" tags in some cases.
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.
lyx2lyx sets all new math packages to off when converting from old formats.
This is correct if any command which would cause an automatic package loading
exists in the document. However, it is wrong if no command exists: This leads
to problems if later a command is added (bug #9069), which is especially
annoying for templates.
The fix consists of two parts:
1) convert_use_package() considers now the used commands like
revert_use_package(), and uses them to decide whether to set the package to
auto or off.
2) convert_undertilde() and revert_undertilde() use a slightly adjusted copy of
convert_use_package() and revert_use_package(), so that the bug is also
fixed for undertilde. We cannot use the latter functions directly, because
of "\usepackage undertilde" vs. "\use_undertilde".
When doing the lyx2lyx round trip of the 2.0.8 user guide from format
413 -> 474 -> 413 you get an invalid document, because the math packages
mhchem and undertilde are incorrectly converted.
It turned out that the old reversion code did only work for particular
package oderings. The new one works for abitrary sorted packages.
When doing the lyx2lyx round trip of the 2.0.8 user guide from format
413 -> 474 -> 413 you do not get a zero diff. The most important problem is
caused by the conversion of the argument insets to the old syntax: This
conversion adds an additional empty line (harmless), and it destroys the
document structure if the first inset in e.g. a subsection is not an argument
inset, but e.g. an index or label inset.
The fix is quite easy: Ensure that the paragraph begin is set to the first
argument inset.
revert_justification() issues a warning if the \justification parameter does
not exist, and LyX itself always writes it unconditionally as well, so add it
also in lyx2lyx when converting old documents.
Currently this does not have any user visible effect, but it decouples the
default value of BufferParams::justification from the conversion of old
documents: Now it is possible to set the default to false in LyX, and old
documents will still be converted correctly.
Compilation was failing with TeX Live 2013 because of
the format of one of the references. This commit just
changes one of the references to a different one.
As discussed. achemso.layout contains both "Chart" and "Graph", therefore it
does not make sense to use "Graph" in the "Chart" / "Graph" / "Diagram" sense,
but in the mathematical sense like in "graph theory".
Therefore I added the context [[mathematicl]].
All translations are unchanged except the german one, which is now again
"Graph" as in 2.0.0 instead of "Schaubild".
This string was not picked up by the script to generate the layouttranslations file. After deleting the file and re-running the script, this string was picked up.
- this brings back all our template files (they are no example files, would have been a regression otherwise because LyX 2.0 offers them already in "new from template")
- the thesis files will stay in the examples folder for now until we have a real fiix for bug #8643
I only left out the following:
1) chinese translation - we have no GPL statement yet, if we don't get it the
big update would need to be removed unfortunately.
2) I kept the dutch translation for "Chart", although this is ambigous, since
nl.po does not contain a translation
3) I kept the danish translation for "Note", since da.po does not contain a
translation
The review file is updated as well to contain all translations without a
documented review.
The Japanese math manual was not compiling because of some
complications with foreign language switching. This would
have been fixed after the translation from English to Japanese
is done but I want to make sure the document is compilable
for 2.1.
Now lib/layouttranslations.review contains all translations which have been
changed since the 2.0.0 release except for the ones where the commit log
mentioned that they were reviewed.
The pgf package 3.0.0 update lead to an error being given with
this document. Loading the 'etex' package fixes the problem.
For more information, see:
https://sourceforge.net/p/pgf/bugs/296/
filehook.sty is required when you use non-TeX fonts and also the non-TeX math default font
In the same context LyX requires the font "latinmodern-math.otf", but we can currently not check for it, see my post to the list
I should have had a closer look much earlier, since the fix is simple and
safe, but at that time I did not notice. The problem was that an invalid
.lyx document was created when converting unicode characters with two
backslashes in their LaTeX definition from lib/unicodesymbols to pre-unicode
LyX format.
The frame decoration IconPalette contains already \overset etc. and \sideset has the same logic like \over- and \underset. Moreover we should keep the math panel clean and avoid the listing of many very special commands
