[OS X TeX] Nobody knows

I just noticed Maarten's post on comp.text.tex involving a bash shell 
script to run LaTeX as many times as necessary to get things right with 
figure numbers et al.

Considering TeXShop is all about making Mac the most simple and pleasant 
way of writing LaTeX, why hasn't such a script been implemented?

I suppose alternatively, I could ask "Why doesn't everyone use iTeXMac?" 
or "Why doesn't everyone write ConTeXt?".

To conclude my post of questions no-one will answer (don't use this 
sentence as an excuse, though)---has anything been done by anyone on 
using folder packages to represent TeX documents with a single file?

Given the second part of your reply, you seem to be aware that the
correct table number (or figure number or any other reference for that
matter) only appears after the first run. Try to post a minimal
example that doesn't work for you and report back.

Just grep the log file for errors, this is what i cooked up in bash:

# the masterdocname is set as an argument,
# and the docclass is filtered with perl
# basic run, under full draft mode (speed!)
pdflatex -file-line-error-style -interaction=nonstopmode \
     "\PassOptionsToClass{draft}{$docclass}" \
     "\PassOptionsToPackage{draft}{graphicx}" \
     "\PassOptionsToPackage{draft}{graphics}" \
     "\PassOptionsToPackage{draft}{hyperref}" \
     "\input{$masterdocname}" > /dev/null

# filter for errors, I use bbedit, can be replaced by vi or so.
errors=`perl -e 'while(<>){ if ( /^(\\S+?):(\\d+):\\s(?!pdfTeX)/s ) {
     print "bbedit +$2 $1\\n"; } }' ${masterdocname%%.tex}.log`
if [ "$errors" == "" ] ; then
     # run bibtex (needed after the clean sheet)
     bibtex ${masterdocname%%.tex}

# after the bibliography generation at least two runs are needed
     pdflatex -file-line-error-style -interaction=nonstopmode \
         "\PassOptionsToClass{draft}{$docclass}" \
         "\PassOptionsToPackage{draft}{graphicx}" \
         "\PassOptionsToPackage{draft}{graphics}" \
         "\input{$masterdocname}" > /dev/null

# a run without draft, and noninteractive
     crossrefs=`grep 'Rerun' ${masterdocname%%.tex}.log`
     if [ "$crossrefs" != "" ] ; then
         pdflatex -file-line-error-style -interaction=nonstopmode \

     crossrefs=`grep 'Rerun' ${masterdocname%%.tex}.log`
     if [ "$crossrefs" != "" ] ; then
         pdflatex -file-line-error-style -interaction=nonstopmode \
     echo "an error occurred"
     echo "resolve this error before continuing..."
     eval $errors
# end of partial script

(remember that this fragment needs more details (setting some
variables, getting the master document if you happen to run it on a
part, ...)
