Reverse lookup from pdf to org?

Reverse lookup from pdf to org?

[Rainer M Krug]

[-- Attachment #1: Type: text/plain, Size: 718 bytes --]

Hi

I am working on a longish document which will be converted to pdf, and I
am doing debugging of scripts at the moment.

Therefore I export the document to pdf, and look for errors there. Now I
have to find the corresponding section in the org file - possible, but
tedious.

Would it be possibler to include reverse-lookup in org, so that I click
in the pdf, and the cursor jumps to the position in the org document? I
really like this feature when e.g. using LyX. 

I have no idea how this could be implemented and if this would be
difficult, but I think this could be a useful feature for longer documents.

Cheers,

Rainer

I think this is only possible with synctex.  See this thread:
<http://thread.gmane.org/gmane.emacs.orgmode/78111>

Hope this helps,

Not quite what you have in mind and maybe only a half-measure but when I
produce draft latex documents I like to turn on this package:

\usepackage[color]{showkeys}

It prints the symbol used for labels, references and citations in light
gray in the PDF output.  I can then search for these in the tex to find
the corresponding region.  To the extent they are set in your .org
source you might do similar.

A little screen cap is attached to show an example output.

One more (half-)possibility is as follows: produce the tex file and
compile it not with pdflatex, but with plain latex, producing a DVI
file. Passing the -src option to the latex invocation inserts "source
specials" into the DVI file that some DVI viewers (in particular, xdvi)
can interpret to jump back from the DVI view to the (approximate)
corresponding location in the tex file:

      latex --shell-escape -src foo.tex
      xdvi foo.dvi

C-<mouse1> at a location invokes your editor of choice (presumably
emacsclient) on the tex file and puts point in the general vicinity.

Invoking pdflatex with -src does not elicit any complaints, so it might
actually insert "source specials" in the PDF file, but even if it does I
don't know if any viewer is capable of interpreting them - xpdf does not
seem to be.

And it also leaves you in the tex file, not in the org file - hence
a half-possibility, or maybe even less.

Okay, here is a crazy idea.  Maybe one can use hyperref and place \url{}
and/or \href{}{} macros in the org file.  These will turn into clickable
links in the final PDF.  In them place URLs that look like:

  file:///path/to/foo.tex.orglink?line=42

And then use .mailcap (or whatever MIME config that xpdf/evince/etc
honors) to map the .orglink extension to a script that parses the URL
(does that full URL get passed?) and invokes emacs to open foo.tex at
line 42?

If that much can be made to work (big if!) I see one problem in that the
/path/to will break if the source is moved.

Chance of success: 10%

Yes - but is there any progress to get it working? The file is not
included in the contrib directory.

In another thread Aaron says he does not use it regularly, and finds the
solution too "fiddly".  I guess that would mean there has been no more
progress on this.

I like the idea of reverse links - could be a nice addition when
enabled.

But jumping to the .org file would be the aim - right?

That would not be a problem, as this would primarily be a debugging /
draft feature.

I guess higher?

Yes, right.  Maybe a better example is:

  file://foo.orglink?line=42

which might get interpreted as "go to line 42 in ./foo.org".

This example is also a relative link which would be less brittle as long
as foo.org and foo.pdf are kept together in the same directory.

I like your optimism!

calling

,----
| emacs +42 foo.org
`----

should open the file foo.org and put the cursor in line 42.

Yes - that would be quite useful.

I am an optimist :-)

In most cases, it would be better to use emacsclient, otherwise
you might end up with many emacs instances; but more importantly
perhaps, using emacsclient avoids the initialization delay.

True - this was just a "proof of concept" kind of snippet.

You really are.

Inserting stuff like this into the TeX file /may/ very easily break it,
in the sense that it does compile, but /looks/ different (read: has
different line and/or page breaks) than without it.  (Though it /might/
be possible, I'm only saying that it would require much TeX expertise
and being very careful.  In fact, TeX4ht seems to do something similar
(though I never used it), so maybe I'm too pessimistic;).)
