Yes, the file format for 1.7 has evolved---partly to support XeTeX. But
you can always export to 1.6 format---as I guess got discussed in
detail. As Guenter suggested, the even better thing to do is just copy
the entire lyx2lyx directory from svn over to your 1.6 directories. Then
you don't have to worry about it.

Thanks for all the suggestions. It looks like it's time to give lyx-devel 
another try.

Cheers,

Re: XeLaTeX in LyX 1.7/2.0

[Rob Oakes]

I updated to the svn trunk version this morning and I can verify that
any file modified by the new version, indeed, cannot be reverted be read
by v1.6 or earlier.  When I was playing with the svn version back in
August, this would have been an enormous problem since it seemed
extremely unstable.

It appears that the developers have since fixed a number of those
problems, though.  I've been using it all morning to work on the text
for my book without a single hiccup.  (After I figured out that I needed
to specify a different -sysdir and -userdir or it would completely crap
over my previous installation).  I also fumbled around looking for the
xetex settings, but once I got it figured out (it's under
Document-Settings-Output for anyone else who might find themselves
confused), I've been a very happy camper.

The one feature that I would like to try out and can't seem to enable is
the new spell checker.  Squiggly red underlines is something that I've
wanted to see in LyX for a very long time.

Cheers,

Rob

I wonder if the file format used in trunk (or rather
the lyx2lyx converter that deals with it) is still
unable to revert back to previous versions' file formats. 

What do you mean by unable to revert back ? LyX trunk uses a new file
format (of course) and the older LyXes don't know about the new
fileformat.

Did you try File-Export-LyX 1.6.x ? 

Vincent

RE: XeLaTeX in LyX 1.7/2.0

Hi Vince,

I was aware that newer versions of LyX use a different file format.  I
meant only that you have to manually export the document to an older
version of LyX.  The lyx2lyx script is not capable of doing so on its
own.

My fault for not being clear.

No, that's because you'll have to tell the lyx2lyx script that you want
the 1.6.x file format. It would be wrong to save the documents in 1.6.x
format by default (losing new features on the road).

any file modified by the new version, indeed, cannot be reverted be read
by v1.6 or earlier.  When I was playing with the svn version back in
August, this would have been an enormous problem since it seemed
extremely unstable.

It appears that the developers have since fixed a number of those
problems, though.  I've been using it all morning to work on the text
for my book without a single hiccup.  (After I figured out that I needed
to specify a different -sysdir and -userdir or it would completely crap
over my previous installation).  I also fumbled around looking for the
xetex settings, but once I got it figured out (it's under
Document->Settings->Output for anyone else who might find themselves
confused), I've been a very happy camper.

The one feature that I would like to try out and can't seem to enable is
the new spell checker.  Squiggly red underlines is something that I've
wanted to see in LyX for a very long time.

Cheers,

Rob

What do you mean by unable to revert back ? LyX trunk uses a new file
format (of course) and the older LyXes don't know about the new
fileformat.

Did you try File->Export->LyX 1.6.x ?

Hi Vince,

I was aware that newer versions of LyX use a different file format.  I
meant only that you have to manually export the document to an older
version of LyX.  The lyx2lyx script is not capable of doing so on its
own.

My fault for not being clear.

Cheers,

Rob

I did---at the time---and it did not work as advertised. So there was no way
I could  stop using Lyx 2.0 at a later point. If that's no longer the case,
I'll give it another try. Like Rob, I have been longing for those red
squiggles for a long time...

No, that's because you'll have to tell the lyx2lyx script that you want
the 1.6.x file format. It would be wrong to save the documents in 1.6.x
format by default (losing new features on the road).

If it doesn't work, that's a serious bug and we would like to hear it so
we can fix it. At all times, trunk should be able to export to the older
fileformats.

This saves the file as *.lyx16, which will not be found by the
File>Open with the standard (*.lyx) filter!

(I still long for the implementation of a filename selector with
File>Export.)

However, you can replace the LyX 1.6 version of lyx2lyx with the SVN
version and it will automatically downgrade the file format if you open
it in LyX.

Not utterly save (make a backup of the old version) but very convenient.

I was about to make the same suggestion.

Note that the svn version of lyx2lyx should be identical to the 1.6 
version so far as the import of older documents is concerned. The only 
differences should lie in what is newer. Of course "should" does not 
mean "is", but a quick diff shows that is more or less true. So it is 
pretty safe.
