Re: Exporting to RTF

2009-03-11 Thread Nikos Alexandris

Nikos:
 I need some help. I have an article (for a Newsletter) which I have to
 deliver today. I am trying unsuccessfully to export my document _at
 least_ as an RTF to make my colleague's life easy :-).
 [I still have problems with all kinds of _external_ file formats]

 I get the following error in the terminal:
 (Not set):213 Error! More than 100 PushSource() calls
 Error: Cannot convert file
 
 Any hints?
 Thanks in advance, Nikos


OK, I managed to get something. I removed all commands from the Preamble
and all figures from the document (some svg caused problems - don't
appear with their correct size in the produced RTF) and I get something
which is more or less ready to work with.

Cheers, Nikos

I did indeed do reconfigure and restarted LyX.

LyX complains about the file with the following:

The layout file requested by this document,

available. See the Customization documentation
for more information.
LyX will not be able to produce output.

I confirm that I do have APA installed:

$ kpsewhich apa.cls
/usr/share/texmf-texlive/tex/latex/apa/apa.cls

Perhaps apa.layout was included in the ubuntu 1.4.x package, but not in
1.5.1?



Don't know the answer to that -- I haven't installed an ubuntu package 
(yet -- it's on my to-do-someday list).  You should be able to find the 
layout files in LyX root/Resources/layouts and confirm whether 
apa.layout is there.  If not, I can easily e-mail it to you.  I'm pretty 
sure you have the layout file, though:  you posted earlier that it was 
listed in LyX as unavailable.  If you didn't have the layout file, it 
would not be listed at all.


You might confirm (via kpsewhich) that apacite.sty is also installed. 
If I'm reading apa.layout correctly, it tells LyX that apacite.sty is 
also used.  I'm not sure what would happen if the configuration package 
found apa.cls but not apacite.sty.


As of version 1.5.x at least, when you reconfigure LyX, it writes a log 
file in your user directory (at least on Windows).  If present, it will 
tell you whether it searched for, and whether it found, the APA class. 
For instance, mine has


+checking for document class apa [apa,apacite.sty]... yes

If there's no checking for message, it didn't see a layout file.  If 
there's a message but it says no, it found the layout file but not the 
class or style file(s).

Nothing about rtf in export either, I can see Rich Text Format in
Export - Custom, but OK and Apply are ghosted. Actually both
are ghosted for all the formates listed (See screenshot attached).

Perhaps these issues are a packaging problem? If I knew how LyX was
supposed to behave I could submit a bug report to ubuntu.

You can try latex2rtf (LyX will recognize it when it is installed and
