#!/bin/bash
# This script is a make file for tex4ht. It is written in bash
# but should be simple to translate into csh, perl or whatever your platform
# prefers.
# Original author: Kai-Mikael Jää-Aro <kai@popwire.com>
#
# This code is placed under the LaTeX Project Public License
# (http://www.latex-project.org/lppl.txt).
#
# Motivation:
# The LaTeX file has to be compiled until the dvi file stabilises.
# We check on auxiliary files to determine if a new compilation will change
# anything or if we are done now.
#
# This script takes seven arguments:
# $1 The LaTeX file
# $2 Files to be included by latex
# $3 Options to tex4ht, of which the first must be a font directory
# $4 Options to t4ht
# $5 Options to latex/tex
# $6 Package inclusions to create the desired type of document
# $7 A user-supplied script which will be executed each time around the loop
# $8 A user-supplied test which should have an exit value of 0 if we need to
# compile the file again.
#
# Sometimes, typically due to moving page references in the text, a file will
# never converge, so there is a checkpoint every TEX4HTLIMIT iterations
# (default 10). If TEX4HTBATCH is set the script will just exit the loop,
# otherwise it asks the user whether to continue. If the output is
# deemed not to have converged, the script will return a status of 1,
# otherwise 0.

# There are (rare) instances when the process actually does not converge,
# so we give the users a heads up every few times around the loop, so they
# can decide if they hadn't better check what's going on.
# (I prefer this to a fixed cut-out as tex4ht does not have a known upper
# limit on the number of iterations necessary for unknown input.)

cp ${file}.4tc ${file}-old.4tc

# This is the logic here:
# If LaTeX tells us we need to rerun, we do so without further discussion,
# otherwise we check if any of the .4tc, .xref, .aux files is different from
# the previous version.
# Finally we use the user-supplied test to see if there is anything more to do.
# If none of these tests trigger, we're done.
