Often proceedings give authors sample .tex files to demonstrate how a paper should be formatted. I generally want to make my preamble as close as possible the sample. Usually I can trick LyX into generating something pretty close to the sample preamble, but before submitting manually tweak the .tex file to remove unneeded options etc. For lolz, I spend a couple of days in LyX getting the pagination just right, then discover that the pagination changes once I manually fix the preabmle in the .tex file. Additionally, it is much faster to cut-and-paste a preamble than it is to hunt round in LyX to find all the options. For these reasons, I use a wrapper script around pdflatex like the one below.
However I was wondering if this sounds like a good feature for LyX itself? My suggested implementation would be that you can set an option in Document Settings->LaTeX Preamble like "edit whole preamble". When this option is set LyX copies the whole preamble into the text box, and allows the user to edit it as normal text. -- pdflatex -- #!/bin/bash THIS_SCRIPT="$0" echo AT "$@" echo AT "$@" 1>&2 echo AT "$@" > /tmp/AT echo "$*" | grep -o '\b[^ ]*.tex' | head -n1 | ( read texfile echo TEXFILE $texfile mv $texfile $texfile.orig grep '^%PREAM ' $texfile.orig | sed 's/^%PREAM //' > $texfile "$THIS_SCRIPT".strip_preamble.py < $texfile.orig >> $texfile /usr/bin/pdflatex "$@" rm $texfile.mod mv $texfile $texfile.mod mv $texfile.orig $texfile ) -- pdflatex.strip_preamble.py -- #!/usr/bin/env python import sys preamble=True; for line in sys.stdin: if preamble: if line == '\\begin{document}\n': preamble=False print line, else: print line, -- John C.
