LyX file-format changes
-----------------------§
2007-01-31 Uwe Stöhr
* format incremented to 258: new \lyxline definition
Old:
\\newcommand{\\lyxline}[1]{
{#1 \\vspace{1ex} \\hrule width \\columnwidth \\vspace{1ex}}
}
New:
\\newcommand{\\lyxline}[1][1pt]{%
\\par\\noindent%
\\rule[.5ex]{\\linewidth}{#1}\\par}
The new definition is more robust, see bug 1988 and now really takes care about
the fontsize: \lyxline{\Huge} produces now a thicker line then \lyxline{\normalfont}
2006-12-22 Georg Baum <Georg.Baum@post.rwth-aachen.de>
* format incremented to 256: allow some new inputenc settings.
For the complete list, see lib/lyx2lyx/lyx_1_5.py.
2006-11-25 Georg Baum <Georg.Baum@post.rwth-aachen.de>
* format incremented to 255: new insets for \clearpage and
\cleardoublepage. They are written inline to the file, exactly like
\newpage.
2006-11-13 Georg Baum <Georg.Baum@post.rwth-aachen.de>
* format incremented to 254: new header parameter \use_esint.
It can have the same values as \use_amsmath: 0 (off), 1 (auto) and
2 (on).
2006-10-18 Georg Baum <Georg.Baum@post.rwth-aachen.de>
* format incremented to 253: new nomenclature and printnomenclature
insets. These are standard InsetCommand with the following parameters:
\nomenclature[prefix]{symbol}{description}
\printnomenclature[labelwidth]
2006-10-15 Georg Baum <Georg.Baum@post.rwth-aachen.de>
* format incremented to 252: changed command inset syntax
Old:
\begin_inset LatexCommand \cmdname[opt1][opt2]{arg}
preview true
\end_inset
and
\bibitem [opt1]{arg}
New:
\begin_inset LatexCommand cmdname
name1 "opt1"
name2 "opt2"
name3 "arg"
preview true
\end_inset
The order of the parameters and for each parameter the name and
optional/required bit is now stored in InsetCommandParams.
2006-10-03 Jürgen Spitzmüller <j.spitzmueller@gmx.de>
* format incremented to 251: save show_label param for charstyles.
On revert, the show_label param is just removed. Nothing to convert.
2006-10-12 Martin Vermeer <martin.vermeer@hut.fi>
* Format incremented to 250: allow optional arg to environments
No material format change. Now optargs for environments are allowed
to be specified in layout files and will be handled properly. When
converted back to older formats, they will be ignored in LaTeX
output.
2006-08-14 Georg Baum <Georg.Baum@post.rwth-aachen.de>
* format incremented to 249: Unicode
LyX documents are now always encoded in utf8. The value of
\inputencoding does now only determine the encoding of the created
LaTeX file.
Up to format 248 the value of \inputencoding did also determine the
encoding of the LyX file:
\inputencoding LyX file encoding
auto as determined by the document and character
languages
default ditto
everything else as determined by \inputencoding
The difference between auto and default is only the LaTeX output:
auto causes loading of the inputenc package, default does not.
2006-07-03 Georg Baum <Georg.Baum@post.rwth-aachen.de>
* format incremented to 248: Basic booktabs support
The <features> tag has a new switch: booktabs="true|false".
An absent switch is equivalent to booktabs="false".
Horizontal lines are set with the booktabs package if this switch
is on.
The <row> tag of tabulars has the following new attributes:
topspace, bottomspace and interlinespace. All take a LyXLength
as value, or the special keyword "default".
2006-06-10 Jürgen Spitzmüller <j.spitzmueller@gmx.de>
* format incremented to 247. The Grand Font Interface Rewrite.
(1) Split font selection to rm, sf, tt:
\fontscheme -> \font_roman, \font_sans, \font_typewriter
Change 246->247:
\fontscheme \font_roman \font_sans \font_typewriter
default default default default
ae ae default default
times times default default
palatino palatino default default
helvet default helvet default
avant default avant default
newcent newcent default default
bookman bookman default default
pslatex times (or \usepackage{pslatex})
New 246->247:
\font_roman: cmr (-> \renewcommand{\rmdefault}{cmr}),
lmodern, charter, utopia, ccfonts, chancery, beraserif
(-> \usepackage{<name>})
\font_sans: cmss, lmss, cmbr
(-> \renewcommand{\sfdefault}{<name>})
berasans (-> \usepackage{<name>})
\font_typewriter: cmtt, lmtt, cmtl,
(-> \renewcommand{\sfdefault}{<name>})
courier, luximono, beramono
(-> \usepackage{<name>})
(2) New param \font_default_family (rmdefault, sfdefault, ttdefault)
(3) New param \font_sc (true, false).
(4) New param \font_osf (true, false).
(5) New param \font_sf_scale (float)
(6) New param \font_tt_scale (float)
Support for the following fonts has been added:
bera, ccfonts, chancery, charter, cmbright, computer modern (explicitely),
courier, lmodern, luximono, utopia.
Support for the following font has been removed:
pslatex (it's superseded by mathptmx (times)).
2006-06-03 Martin Vermeer <martin.vermeer@hut.fi>
* format incremented to 246. The framed.sty package is
now supported with note types framed and shaded.
2005-10-12 Jürgen Spitzmüller <j.spitzmueller@gmx.de>
* format incremented to 245. The \quotes_times parameter
has been removed.
2005-09-24 Jürgen Spitzmüller <j.spitzmueller@gmx.de>
* format incremented to 244. Rename '\InsetSpace \,'
to '\InsetSpace \thinspace{}', because the comma was
not parsed by lyxlex, and '\InsetSpace \space' to
'\InsetSpace \space{}' in favour of consistency.
2005-07-18 José Matos <jamatos@lyx.org>
* format incremented to 243.
* this change only affects the preamble, the paperpackage
option was removed and papersize is changed to default.
2005-06-21 Jean-Marc Lasgouttes <lasgouttes@lyx.org>
* format incremented to 242. There is no file format per
se, but the "frenchb" language has been removed from lib/language
and has to be translated to "french" by lyx2lyx.
2005-02-03 Georg Baum <Georg.Baum@post.rwth-aachen.de>
* format incremented to 241.
All following changes apply only to text in ERT insets. The
rationale is that text in ERT is simply ASCII text, and nothing more.
* paragraph breaks are now a single newline in latex and not a
paragraph break anymore (bug 698).
* \newline is not allowed anymore, because it is redundant (see above)
* layouts other than Standard, paragraph parameters and font changes
are not allowed anymore. They never made sense and were ignored for
latex output, but now they can't be read or set anymore (bug 922).
2005-01-23 Jürgen Spitzmüller <j.spitzmüller@gmx.de>
* format incremented to 240.
* new bufferparam:
\output_changes {true|false}
(should the change tracking marks be visible in the output or not?)
* lyx2lyx should just delete the param in 239.
2005-01-06 José Matos <jamatos@lyx.org>
* format incremented to 239.
* the paragraph parameters are displayed in their own line. This
change is consistent with the insets behaviour, and corresponds
to a more uniform treatment of the paragraphs since some of them
had already their own line.
An example of a single paragraph follows:
\begin_layout Standard
\paragraph_spacing single
\align left
Paragraph text.
\end_layout
2004-12-03 José Matos <jamatos@lyx.org>
* format incremented to 238.
* The compatibility code to read old latex accents from 0.12.x in
InsetLatexAccent::checkContents has been removed.
The following translations are done:
"\i \x" -> "\i \x{}"
"\i \xy" -> "\i \x{y}"
"\i \x y" -> "\i \x{y}"
"\i \x\i" -> "\i \x{\i}"
"\i \x\j" -> "\i \x{\j}"
x is a latex accent command, y the base character. \, i and j are
literal.
lyx did these changes already from 0.12.x -> 215, but not lyx2lyx,
so formats 215 - 237 can have both versions.
2004-10-10 José Matos <jamatos@lyx.org>
* format incremented to 237.
* In the header, the following statments use now booleans values,
instead of 0, 1:
- \use_geometry
- \use_bibtopic
- \tracking_changes
2004-08-15 José Matos <jamatos@lyx.org>
* format incremented to 236.
* Added tags:
- \begin_document
- \begin_header
- \begin_body
- \end_body
* The options for \papersize are changed:
Default -> default
Custom -> custom
* All whitespaces are removed at the end of lines, when
not necessary. As an example we have all the lines in the header that
do not belong to the preamble.
2004-07-01 Georg Baum <Georg.Baum@post.rwth-aachen.de>
* format incremented to 235.
* \paperpackage had an off-by-one error. Translation table:
234: a4 a4wide widemarginsa4
235: none a4 a4wide widemarginsa4
The "widemarginsa4" setting of 235 has no equivalent in 234.
2004-05-12 Angus Leeming <leeming@lyx.org>
* format incremented to 234.
* the citation engine is specified explicitly rather than being
deduced from 3 bools.
\use_natbib 1
\use_numerical_citations 0 -> \cite_engine <style>
\use_jurabib 0
where <style> is one of "basic", "natbib_authoryear",
"natbib_numerical" or "jurabib".
2004-04-29 Georg Baum <Georg.Baum@post.rwth-aachen.de>
* format incremented to 233.
* insetgraphics does not allow filenames without extension anymore.
The complete filename has to be given.
2004-03-29 Jürgen Spitzmüller <j.spitzmueller@gmx.de>
* format incremented to 232.
* Support for bibtopic (sectioned bibliographies).
- bufferparam \use_bibtopic [1|0]
- the bibtex inset has a second argument for bibtopic's
btPrint{Cited|NotCited|All} command:
< 231:
\begin_inset LatexCommand \bibtex[<style>]{<database>}
now:
\begin_inset LatexCommand \bibtex[<style>][<btPrintX>]{<database>}
Forwards, there's nothing to be done. Backwards, \usepackage[dot]{bibtopic}
has to be inserted to the preamble. Instead of the bibtex inset, the LaTeX
\bibliographystyle{<style>}
\begin{btSect}{<database>}
\<btprintX>
\end{btSect}
has to be inserted.
2004-03-29 Jürgen Spitzmüller <j.spitzmueller@gmx.de>
* format incremented to 231.
* Support for sidewaysfigure/sidewaystable (rotating package).
insetfloat has now a param \sideways [true|false] (default is false).
The param should be erased on downwards conversion, if it was true,
the inset should be replaced by
\begin{sidewaysfigure} <content> \end{sidewaysfigure}
resp.
\begin{sidewaystable} <content> \end{sidewaystable}
i.e. ERT.
2004-02-23 Jürgen Spitzmüller <j.spitzmueller@gmx.de>
* format incremented to 230.
* Support for a second optional argument in insetcommand.
currently, citation uses this to support natbibs second
optional argument \cite[before][after]{key}.
I think there's nothing to convert upwards. Downwards, the
commands with 2 optional args need to be converted to ERT.
* Support for jurabib (param \use_jurabib [1|0], default is 0).
When converting downwards, \usepackage{jurabib} has to be added
to the preamble and, if babel is used, \usepackage{babel} before
(jurabib fails if babel is called afterwards). If the natbib commands
are used together with jurabib, they have to be converted to ERT too.
2003-12-29 Jürgen Spitzmüller <j.spitzmueller@gmx.de>
* format incremented to 229.
* Minipages cannot be read anymore. All minipage insets will
be converted to frameless box insets between 228->229.
2003-12-15 Angus Leeming <leeming@lyx.org>
* format incremented to 228.
* Change the output of all insets derived from InsetCollapsable
except for InsetERT (which has a similar output already), changing lines
"collapsed true" -> "status collapsed"
"collapsed false" -> "status open".
* Change the output of InsetERT, changing lines
"status Collapsed" -> "status collapsed"
"status Open" -> "status open".
"status Inlined" -> "status inlined".
2003-12-10 Angus Leeming <leeming@lyx.org>
* format NOT incremented.
* add a 'draft' option to InsetExternal.
2003-12-10 Angus Leeming <leeming@lyx.org>
* format incremented to 227.
* Change the output of InsetBox:
\begin_inset Boxed -> \begin_inset Box Boxed
\begin_inset Doublebox -> \begin_inset Box Doublebox
\begin_inset Frameless -> \begin_inset Box Frameless
\begin_inset ovalbox -> \begin_inset Box ovalbox
\begin_inset Ovalbox -> \begin_inset Box Ovalbox
\begin_inset Shadowbox -> \begin_inset Box Shadowbox
2003-12-10 Angus Leeming <leeming@lyx.org>
* format incremented to 226.
* Change the output of InsetNote:
\begin_inset Note -> \begin_inset Note Note
\begin_inset Comment -> \begin_inset Note Comment
\begin_inset Greyedout -> \begin_inset Note Greyedout
2003-11-28 André Pönitz
* Remove space_above/space_below from Paragraph.
This is now handled by InsetVSpace.
2003-10-07 Angus Leeming <leeming@lyx.org>
* Add transformations to InsetExternal
boundingBox 0 0 20 20 the dimensions of the B.B..
Output if the B.B. is not empty.
clip clip the image to the B.B.
Output if true.
extra LaTeX "draft" 'extra' data passed to the primary
command for this output format.
(Possible formats LaTeX, PDFLaTeX,
LinuxDoc, DocBook, Ascii.)
The string can contain spaces and so
is wrapped in "...".
rotateAngle 30 Rotation of the data.
Output for non-zero rotation only.
rotateOrigin bottomleft Rotation origin.
Output for non-zero rotation and
non-default origin (center) only.
scale 50
width 2cm Output only if the image is resized.
height 2cm
keepAspectRatio
2003-10-07 Martin Vermeer <martin.vermeer@hut.fi>
* Added box inset. File format:
\begin_inset Ovalbox Boxed/Frameless/ovalbox/Ovalbox
/Shadowbox/Doublebox
position "b" t/c/b
hor_pos "c" l/c/r/s
has_inner_box 1 1/0
inner_pos "b" t/c/b/s
use_parbox 0 1/0
width "100col%" unit+width-string
special "none" none/height/depth
/totalheight/width
height "1in" unit+width-string
height_special "totalheight" none/height/depth
/totalheight/width
collapsed false true/false
\begin_layout Standard
<box contents>
\end_layout
\end_inset
This box (Frameless, has_inner_box=1, use_parbox=0) replaces
the pre-existing Minipage inset. Parameters translate as follows:
position 0/1/2 -> t/c/b
inner_position 0/1/2/3 -> inner_pos c/t/b/s
height same
width same
collapsed same
2003-08-19 Michael Schmitt <michael.schmitt@teststep.org>
* attribute valignment="center" is replaced by valignment="middle"
for tabular columns and cells
2003-08-17 Martin Vermeer <martin.vermeer@hut.fi>
* Added branch inset. File format:
branch definition in the header:
\branch <branchname>
\selected 0 0/1
\color #rrggbb
\end_branch
\begin_inset Branch <branchname>
collapsed false true/false
\begin_layout Standard
<branch contents>
\end_layout
\end_inset
2003-07-28 José Matos <jamatos@lyx.org>
* \the_end is replaced with \end_document
2003-07-28 José Matos <jamatos@lyx.org>
* \layout is replaced with \begin_layout
2003-07-28 José Matos <jamatos@fep.up.pt>
Format bumped to 225
* All layouts finish now with \end_layout
2003-06-04 Angus Leeming <leeming@lyx.org>
Format bumped to 224
* the storage of the external inset has been changed from
\begin_inset External XFig,"file.fig",""
\end_inset
to this
\begin_inset External
template XFig
filename file.fig
display <display_type>
lyxscale <scale>
\end_inset
throwing away the final arg (here "", more generally "<string>") that holds
the parameters variable.
Variables are output if present (filename) or different from the default
values (display, lyxscale).
Moreover, the RasterImage template has been scrapped. All RasterImage
external insets are now converted to Graphics insets.
2003-05-20 Jürgen Spitzmüller <j.spitzmueller@gmx.de>
* Added new space insets:
\SpecialChar ~ is now \InsetSpace ~
ERT: "\ " could be converted to InsetSpace \<space>
ERT: "\," could be converted to InsetSpace \,
2003-04-24 André Pönitz <poenitz@gmx.net>
* Added eqref support:
\begin_inset LatexCommand \eqref{label}
2003-03-14 Dekel Tsur
* Format bumped to 223.
2003-03-12 John Levon <levon@movementarian.org>
* Added \\end_header to signify the end of the header in a
more robust fashion.
* use_amsmath is now a tristate {0 = never, 1 = auto, 2 = always}
2003-02-10 John Levon <levon@movementarian.org>
Format bumped to 222
Added \\tracking_changes 0|1 to the header.
Added \\author to the header. This can be present multiple
times, and is of the form :
\\author "Real Name" email@address.com
Added \\change_deleted, \\change_inserted. Each of these does not
span a paragraph, and is delimited by "\\change_unchanged\n". Both are
of the form :
\\change_inserted author time
where author is an integer ID reference into the author list in
the header, and time is time_t.
2002-10-24 Rob Lahaye <lahaye@snu.ac.kr>
* insetgraphicsParams.h (scale): is now a float, not an unsigned int.
2002-08-22 Rob Lahaye <lahaye@snu.ac.kr>
New graphics dialog. With the removal of buttons in the dialog, also
keywords in the graphics inset went. The following keywords do not
exist anymore:
lyxsize_kind
lyxsize_type
lyxwidth
lyxheight
size_kind
size_type
rotate
Only non-default values are saved to the lyx files. The defaults of the remaining
keywords are;
filename <empty>
lyxscale 100
display default
scale 100
width <empty>
height <empty>
draft <off>
noUnzip <off>
BoundingBox <from file>
clip <off>
rotateAngle 0
rotateOrigin centerBaseline
subcaption <off>
subcaptionText <empty>
special <empty>
The remaining keywords have sufficient overlap with the old ones for a
smooth reading of the 1.2.x inset keywords in most common cases.
Compatibility is certainly broken for the old lyxwidth/lyxheight keywords.
They don't exist anymore and we can't translate them into a scaling value, while
we're reading the graphics inset. The old lyxwidth/lyxheight keyword and its
argument is ignored and lost.
Only few compatibility issues are left for lyx2lyx:
------------------------------------------------------------------------------
old-token new-token remove
------------------------------------------------------------------------------
size_kind original / size_type 0 scale 100 width <val>
height <val>
scale <val>
size_kind width_height / size_type 1 - scale <val>
lyxsize_kind original / lyxsize_type 0 lyxscale 100 lyxscale <val>
------------------------------------------------------------------------------
[replace old-token by new-token, and remove any of subsequent tokens as listed]
If "rotate" is absent, lyx2lyx should ignore "rotateAngle <val>":
if ( "rotateAngle <val>" is there WITHOUT being preceded by the keyword "rotate" )
then
replace "rotateAngle <val>" by "rotateAngle 0"
2002-08-12 Andre' Poenitz <poenitz@gmx.de>
Added \lyxlock for locked math inset when written to .lyx file.
When "downgrading" .lyx files this should simple be deleted but it
does not hurt at all if it stays in. It does not have to be added
when "upgrading".
2002-08-02 Angus Leeming <leeming@lyx.org>
Added a boolean "preview" flag to InsetCommandParams.
Currently it is written only by InsetInclude, because only this
class can generate a preview of its contents.
The LyX file now contains:
\begin_inset Include \input{snapshot_t=40.tex}
+preview true
\end_inset
Earlier versions of LyX just swallow this extra token silently.
2002-08-12 Angus Leeming <leeming@lyx.org>
The 1.2.0 InsetGraphicsParams "size_type" and "lyxsize_type" have been
renamed as "size_kind" and "lyxsize_kind" respectively.
\begin_inset Graphics FormatVersion 1
filename file.eps
display default
- size_kind original
+ size_type original
width 7cm
rotateOrigin center
- lyxsize_kind original
+ lyxsize_type original
lyxwidth 4cm
\end_inset
