All this will become less important once LyX is more scriptable, but
for now being part of the export menu seems to make such a function
much easier to use. I personally will just use a workaround for this
issue for now (wrapping lyx in an additional script that puts figures
into comments before exporting), but there are some more points that
may be worth considering:
Note that having an extra lfun does not necessarily mean that it
will not
show up in the export menu (although Jean-Marc probably meant
that). It
has the advantage that we do not need to duplicate file formats.
If you don't put bare latex export into the Export menu, this would
imply that you consider it more important to have ASCII text export,
than to export the latex format on which LyX itself is based.
Yes, I do consider that more important, because we have the LaTeX
export
with figures. Then comes ASCII (very lossy, but very easy to import
elsewhere), and then comes LaTeX without figures.
One should also consider the following: There is a latex IMPORT menu
item, but none of the present two latex EXPORT functions are really
the inverse of that import. Importing a latex file "original.tex" and
then exporting it again, you will in general lose some or all of the
information about what graphics formats had been present in
"original.tex" (because of the suffix-stripping).
The suffix-stripping has nothing to do with the data loss (apart
from that
I acknowledged on the list and in bugzilla that we need to change
that, so
you are beating a dead horse). Even if it is not stripped you do
not know
whether fig.eps was the original figure in the LyX file, or whether
that
was e.g. fig.tgo.
The LyX->LateX conversion is lossy because the LaTeX file format
can not
store all information that is in the LyX file format, so you can't
do a
100% roundtrip in all cases.
Neither a bare latex export nor the latex export with figures can
therefore
be the 100% inverse of the import function.
The text above refers to the LyX->LaTeX->LyX roundtrip. The
LaTeX->LyX->LaTeX roundtrip has no dataloss because of suffix-
stripping
(tex2lyx emulates the LaTeX serach algorithm for figures). Try it out.
Can you be more specific about what I am supposed to try out (beyond
what I have already reported on the list and in bugs 2762 and 2764)?
