AucTeX and doc-view-mode

AucTeX and doc-view-mode

[David Hansen]

Hello,

Can I get AucTeX to use `doc-view-mode' (and if needed `revert-buffer')
to display the result?  I use Emacs and AucTeX from CVS if the matters.

I don't think that you really want to do that.  Doc-view recompiles the
whole document after it has changed.  And since its MD5 changed, too,
you'll get an additional cache folder in /tmp/doc-view<uid>/ for any
latex run.

I think it's much better to use preview-latex in that case.

That's a doc-view deficiency, it could a dir named !path!to!file or
similar.  Worth a bug report?  I just noted that ~/tmp/doc-view/ is

It's not the same as seeing the document as it would come out of the
printer.  Just think about pictures or the poor syllabication of LaTeX
in non English languages.

But how would doc-view know if the document has to be converted anew?
We could use such a dirname you suggested and add the md5 sum in a file.

The current implementation has the benefit that there will be no new
conversion if you have the document multiple times (or moved it to a new
location).

So both variants have benefits and drawbacks...

Yes, that could be nice.  But to get that right one would need access
timestamps.  AFAIK most users turn them off for their filesystem and I
don't know how portable this is anyway.

But a timestamp file could be added in the cache dir.

Do you have write access to the emacs CVS tree?  If yes it would be
great if you added an item about that to etc/TODO.

Then I'd open the document and hit `r' (or `g') after each latex run.  I
guess you can automate that somehow.
