[texhax] Extract equations as EPS from larger doc?

[Uwe Lueck]

My previous idea more specific, without regarding actual facilities of the extract package: 

redefine the equation environment (resp. others) so it: 

1. writes a file whose <filename> contains the equation number (ususually just expansion of \theequation) and whose content is 

    \documentclass ... \begin{document}
    $$<equation content>\eqno<expansion of \theequation>$$
    \end{document}

2. adds `latex <filename>' to a batch file (or/plus something producing the .eps version if you really need it)

... clearer? 

HTH ... Uwe.

I don't know much of these things, only were busy with parsing .eps with TeX as in the graphics package ... 

.. but this looks like throwing the logical information away and then trying to retrieve it from the glyph placement information, so seems not so sound ... 

The `extract' package -- www.ctan.org/pkg/extract -- seems to address extracting information directly from the LaTeX commands. I cannot judge right now whether it is developped enough right now to handle your task immediately.
