LyX file-format changes
-----------------------
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 \,
2003-03-12 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"

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
