Since lyX 2.0 we support to use the in_preamble tag. This allows to support more commands. For an unknown reason I forgot the jss.layout when I updated the other layouts once.
Fileformat change
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.
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.
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.
Previously, LyX did replace some words with typeset logos, and there was no
way to prvent this except putting them, in ERT (bug #4752). Now we have
special insets for these words, and standard text is left alone.
Previously, 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.
These are now in version.cpp. The build machinery should therefore make sure
that version.cpp is recompiled at every compilation.
These variables are now referred to by the other places that made use of __DATE__ and __TIME__.
This 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.
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.
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.
- 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.
- 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.
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.
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.
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.
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.
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.
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.
These warnings have been (accidentally) commented out in
42aeab2a (uwestoehr; support for table cell rotations;
16-03-2012). In the next commit the warning will be replaced
by a form which is also understood by MSVC.
Currently only basic functionality (our math-tipa functionality plus multipar input). Further enhancements (such as proper unicode input and a specific toolbar) are planned. DocBook and XHTML output also need to be audited.
The lyx2lyx reversion routine surely can be improved (help appreciated), and I don't know tex2lyx enough to handle this file format change.

To avoid duplicity, remove natbib_authoryear and natbib_numerical
and replace them by natbib, and keep track of the engine `type'
in the new \cite_engine_type document setting. This will make it
easier to add more citation engines.
