Indeed it is very useful in my opinion! By the way, sorry for the poor explanation. I'll try to better explain the problem:
*In latex* with a Minimal.tex (attached) you run
latex Minimal.tex
and the line
\usepackage[active,generate=filename,extract-env={align,equation}]{extract}
generate a filename.tex (attached), attaching to it every align and
equation environment found in Minimal.tex.
In my case, however, I'm using *LyX with classicthesis template*. Being it
based on a latex template, I thought it'd be easy to modify the preamble
classicthesis-config.tex (in fact it worked in the past with some other
packages). I tried to add the following lines to the package list loaded
\PassOptionsToPackage[active, \PassOptionsToPackage[active,generate=file,
extract-env={equation,align}]{extract}
\usepackage{extract}
and I got many errors (not relevant showing them, please read the
following).
Then, I tried adding to the Latex preamble
\usepackage[active,generate=file,extract-env={equation,align}]{extract}
via the Document->Setting->LatexPreamble dialog, with a little more luck.
At first, I got many identical errors concerning the package extract
handling of unnumbered equations environment (please refer to the package
documentation):
! LaTeX Error: \begin{XTRalign*} on input line 1 ended by \end{XTRalign}.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.4 \end{XTRalign*}
Your command was ignored.
Type I <command> <return> to replace it with another command,
or <return> to continue without it.
Removing every {align*} and {eqnarray*} environment, leaving numbered
equations only, a proper "file.tex" is created in the temporary log folder,
with every numbered formula attached.So now my questions are:
1. Has anyone encountered the same problem? Do you now any fix to the
align* issue?
2. Do you know any alternative, possibly with a Lyx file output instead of
a latex one? Formatting and tipography issue are not relevant for me, since
this would be just an auxiliary file for me to check while writing.
Thanks in advance
Riccardo
