Increment LyX format to 504.
With this new parameter, the user can indicate that some other parameters that
are frequently switched must not be recorded in the file (as if they were a
setting specific to the user or transient, rather than a document setting). This
will play nicer with version control systems.
See the discussion, e.g.:
http://thread.gmane.org/gmane.editors.lyx.devel/157824/focus=157993 (third
solution mentioned)
TODO:
* The interface remains to be set up. We cannot change this setting from LyX
for now.
* If save_transient_properties is false, we should read the user setting as a
per-user-per-document (session) setting (e.g. like the cursor position).
* Once the above is done, we can treat \justification the same way (but it would
be even better if \justification was moved to lyxrc).
This is one part of bug 9744: If you toggle between TeX fonts and non-TeX
fonts, the settings of the other choice are no longer thrown away, but stored
and re-activated if you switch back. Most parts of the patch are purely
mechanical (duplicating some BufferParams members), the only non-mechanical
change is in the GUI logic.
Being able to compile document with zipped .eps files was a useful feature of
the graphicxs package 20 years ago, but the LyX support is no longer relevant:
- The flag is ignored if preview is on
- If pdflatex is used then uncompressing happens during the compilation anyway
- If set, the flag prevents LyX from issuing proper error messages if
something with the image is wrong
- For hard disk capacities from 20 years ago not uncompressing is a useful
feature, but for current hard disk capacities it does not matter
- The external inset does not have it, and if we want to merge both insets
one day we would need to implement it there, which is even more difficult
than in InsetGraphics
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.
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.
* InsetBox and GuiBox: Use proper empty length instead of the broken -9.99col% trick
* some slight changes to the logic of GuiBox to make sure that values are set as needed.
* lengthToWidget(): handle properly the empty length case. All the other related Qt helpers did it already, it was probably an oversight. Also set the default_unit parameter as optional (not needed in this patch actually, but I got carried away :)
* allow generating LaTeX code for an empty length, since some broken code does that.
The default citation capability of LaTeX is not a true numerical
citation engine, rather it uses a mixture of labels/numbers. Thus
we now distinguish them: "numerical" always increments the bibitem
counter and uses its value as a numerical citation label, while
"default" only uses the bibitem counter when no label is provided.
LyX file format incremented to 471.
These should be used if any new style needs to be introduced in the stable
2.1 series: If the ForceLocal flag of the style is set, it will always be
written to the document header, so that even older 2.1 versions can read
and correctly output the document.
- 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.
