How do I upgrade my existing LyX system to version 1.4.x?
|
|
---------------------------------------------------------
|
|
|
|
The format of the preferences file has changed slightly. LyX 1.4.x is
|
|
able to read old preferences files, but it will save them in the new
|
|
format, so it is not possible to run LyX 1.3.x and 1.4.x with the same
|
|
personal configuration directory.
|
|
|
|
The format of the layout files has also changed, but LyX 1.4.x uses a
|
|
converter layout2layout.py written in python that will convert old layout
|
|
files on the fly. You can also call it manually on your layout files if
|
|
you want to convert them to 1.4.x format permanently.
|
|
|
|
The format of the external template file has changed substantially.
|
|
Automatic conversion is not available, so you need to convert your
|
|
external templates manually. The new format of the external template
|
|
configuration file is described in chapter 6.5 of the Customization Guide.
|
|
|
|
And of course, if you upgrade from LyX 1.2.x, remember that since
|
|
1.3.0, you have to do the following changes:
|
|
|
|
One of the perennial bug bears of LyX users in the past has been that
|
|
they have had to run Edit->Reconfigure when starting their new version
|
|
of the code for the first time. Strange and wonderful things would
|
|
often result if they forgot to do this, so LyX 1.3.0 now runs
|
|
Edit->Reconfigure automatically the first time the program is run.
|
|
|
|
If you have your own layout files, you may need to update them a little:
|
|
|
|
- floats are now defined in the layout file, using the "Float"..."End"
|
|
construct. In most cases, adding "Input stdfloats.inc" to your layout
|
|
file is enough.
|
|
|
|
- counters are also defined in the layout files, using the
|
|
"Counter"..."End" construct. As for floats, adding "Input
|
|
stdfloats.inc" is probably a good idea.
|
|
|
|
And of course, if you upgrade from LyX 1.1.x, remember that since
|
|
1.2.0, you have to do the following changes:
|
|
|
|
- all layout files should have a "DefaultStyle" entry
|
|
|
|
- the "Latex" font style does not exist anymore. If you really need
|
|
its functionality, consider using the "PassThru" keyword instead.
|
|
|
|
The new layout format keywords are described in the Customization
|
|
manual.
|
|
|
|
If you have your own binding files (especially math.bind), you will
|
|
have to update them
|
|
|
|
- math-insert now takes a latex macro name as argument, so that
|
|
"math-insert sqrt" should now be "\math-insert \sqrt"
|
|
|
|
- math-greek-toggle is now gone, and should be replaced by explicit
|
|
bindings like
|
|
|
|
\bind "M-m g a" "math-insert \alpha"
|
|
|
|
|
|
Build requirements
|
|
------------------
|
|
|
|
LyX's graphics handling system has changed substantially. If you
|
|
do not have the JPEG library installed, you may need to install
|
|
it before you can use the graphics capabilities of LyX. If you
|
|
do not have the ImageMagick command-line tools installed, you
|
|
will need to modify the default set up of LyX, or install them,
|
|
in order to get previews of your document's graphics.
|
|
|
|
Document transfer
|
|
-----------------
|
|
|
|
LyX 1.4.x uses an external python script, lyx2lyx, to import documents
|
|
written using previous versions of LyX. All versions of LyX as far back as
|
|
0.12 are supported, so any klyx users still holding out for an alternative
|
|
to xforms will finally be able to put their dinosaur to rest ;-)
|
|
|
|
Of course, this means that you must have python (at least version 1.5.2)
|
|
installed in order to use LyX 1.4.x with your old documents.
|
|
|
|
lyx2lyx also has the framework in place to be able to convert documents
|
|
to an earlier format. However, these converters have only been written
|
|
for the conversion from 1.4.x to 1.3.x, so versions of LyX older than
|
|
1.3.0 will NOT be able to read documents saved with LyX 1.4.x.
|
|
The conversion from 1.4.x to 1.3.x is lossless as long as no new features
|
|
are used. lyx2lyx tries hard to find something equivalent for new
|
|
features such as boxes, but this is known to fail sometimes.
|
|
LyX 1.3.7 contains an updated lyx2lyx that can read documents in 1.4.x
|
|
format. LyX 1.4.x can also export to 1.3.x format for document transfer to
|
|
older 1.3.x releases.
|
|
|
|
If you were previously (in LyX 1.1.x) using the floatflt paragraph
|
|
option to wrap text around a figure, it was necessary to modify this
|
|
for LyX 1.2.0 manually, as described in the manuals. The feature has
|
|
been re-implemented as "Floting figure" inset in 1.3.0. Old files will
|
|
be converted automatically, but you may want to convert the
|
|
1.2.x-style ERT constructs with the native solution (see section 3.8
|
|
of the Extended Features manual).
|
|
|
|
Since LyX 1.2.0, the babel package is loaded after the user-defined
|
|
preamble (because some packages really need to be loaded before
|
|
babel). If you relied, on babel being loaded before your own
|
|
definitions, you can add an extra "\usepackage{babel}" statement at
|
|
the beginning of your preamble.
