Dear LyX developers,

in my post "Import and export to many formats..." [1] sent in the
lyx-users mailing list, Helge Hafting replied as seen below. His text
covers everything (?) and very precise.

My opinion about LyX's import/export capabilities is to super-compress
Helge's words, keep the positive stuff and replace/alter the text in the
"Features" web-page [2] that currently leaves the impression that
everything works out of the box.

For the records: I can't imagine myself working under M$' disorientating
environment (and I hope I'll never be forced to do so). However, the key
to get more users isn't only to self-improve LyX. It's also to make it
really cross-platform and interoperable. This will attract a _lot_ more
users than expected.

I hope that you see my "sceptical point of view" than just say "another
complain from a simple user...". Thank you for your attention,

Nikos

Helge's detailed reply:

The conversions depends on external software. This must be installed
before conversion is possible. Some conversions can be done in several 
ways, with different programs. Some programs do a better job than 
others, so you might get bad results if all you have is the worst
program.

Do not expect all the conversions to yield good results in all cases.
Most of the formats you can export to, is only partially compatible
with 
LyX. So the converted document will at best be different, and at worst 
be useless.

Conversion to latex is about the only conversion that always works 
perfectly. Conversions to pdf, dvi and  postscript goes through latex 
and is normally perfect. But documents using special features may fail 
in some of these conversions. For example, dvi does not support
pstricks.

All other formats have less than perfect conversions.

ASCII obviously looses most of the formatting, as it doesn't support
fonts and images. But then, nobody expects more from ASCII.

Not all features are supported in HTML, so some things may be missing.
Still, LyX can be ok for writing html if you avoid some features.

opendocument/rtf/word is particularly troublesome. The three are 
compatible, and therefore all have the same problems. This is a word 
processor format with a simpler feature set than LyX, so a perfect
conversion will never be possible. In particular, any such conversion 
will loose the good line and page breaking and the hyphenation that LyX 
does so well. After conversion, a document can merely look like a
word document, not better.

Also, this converter is far from finished. Much better conversion to 
word is _possible_, but it looks like nobody/few is interested in 
working on that for free. Developers tend to want to improve LyX itself 
rather than the converters, removing the need for word rather than 
adding compatibility.
