[AUCTeX] Success! [Fwd: Usage of Auctex in conjunction with Noweb and Preview]

[Pjotr Kourzanov]

Dear all,

  I probably should have read the manual better - a simple 
reconfiguration and recompilation of Auctex has put the problem 
to rest at last - I do get previews in Noweb mode now.

  For reference: I only needed to apply the "TeX-file-extensions"
and "TeX-expand-list" tricks to tex.el, and post-process the TeX
.log with "nolatex" script as described below. If anyone needs 
more info, feel free to contact me...

  Thanks again for great tools!

Pjotr

P.S. Here is the nolatex script I've conjured to make it all work:

#!/bin/bash
args=$@
while [[ -n $1 ]]; do
[[ "${1//.tex/}" != "$1" ]] && b=${1//.tex}
shift
done
latex $args |\
sed -e "s,$b.nw.tex,$b.nw,g;s, .*\\\\, \\\\,g;s,\\\\nw[a-z]*{[^{}]*},,g"
