I'm not sure how to go about this in the most effective way, but I'd
thought I'd just throw it out there and see what everyone might come
up with:

The input file is something like this (a fixed size ASCII table:

ESC x x x Description
ESC y y (A) Description2
ESC z (V) Description3
Px = 4 Description5
7 (V) Description6
9 (A) Description7

I'd like to have it come out like this (a LaTeX-formatted table entry):

\verb=ESC x x x= & & Description \\ \hline
\verb=ESC y y= & (A) & Description2 \\ \hline
\verb=ESC z= & (V) & Description3 \\
Px = 4 Description5
7 (V) Description6
9 (A) Description7

....the last few lines will eventually be converted into a
"table-within-a-table". First stab with sed, I would think:

sed '/^ESC/{
s/ *\([VA]\) */ \& \1 \& /;
s/ */ \& \& /;
s/$/ \\\\ \\hline/;
}'

....or did I just solve it? ;-) Bigger challenge: make it come out:

\verb=ESC x x x= & & Description \\ \hline
\verb=ESC y y= & (A) & Description2 \\ \hline
\verb=ESC z= & (V) & Description3 \\
\center
\begin{tabular}{r|c|l}
Px = 4 & & Description5 \\
7 & (V) & Description6 \\
9 & (A) & Description7 \\
\end{tabular}
\end{center} \\

I'm not sure how to make the begin and end (with sed), but since this
is within vi, I can just use a macro to insert them, and do this:

sed '/^ESC/{
s/ *\([VA]\) */ \& \1 \& /;
s/ */ \& \& /;
s/$/ \\\\ \\hline/;
};

/^ /{
s/^ *//;
s/ *\([VA]\) */ \& \1 \& /;
s/ */ \& \& /;
s/$/ \\\\/;
}'

Thoughts? By the way, I know sed a *whole* lot more than LaTeX - so
thoughts on the LaTeX are also welcome...

Thanks! Too bad there's not a comp.lang.sed ;-)

Also, it would seem I can't just use that as given within vim as input
to a !,G command; I'll have to do something else - probably act on a
file and copy it back in...

But there is a comp.lang.awk and awk's probably a more appropriate tool
to use to solve this problem.

You don't explain what information you're keying off to make the
conversions so this may not be how you need it to work, but this will
produce the output you want for the given input:

$ cat file
ESC x x x Description
ESC y y (A) Description2
ESC z (V) Description3
Px = 4 Description5
7 (V) Description6
9 (A) Description7

$ awk -f tst.awk file
\verb=ESC x x x= & & Description \\ \hline
\verb=ESC y y= & (A) & Description2 \\ \hline
\verb=ESC z= & (V) & Description3 \\
\center
\begin{tabular}{r|c|l}
Px = 4 & & Description5 \\
7 & (V) & Description6 \\
9 & (A) & Description7 \\
\end{tabular}
\end{center} \\

$ cat tst.awk
FNR==1 { printf "\\verb=%s %s %s %s= & & %s \\\\ \\hline\n",$1,$2,$3,$4,$5}
FNR==2 { printf "\\verb=%s %s %s= & %s & %s \\\\ \\hline\n",$1,$2,$3,$4,$5}
FNR==3 { printf "\\verb=%s %s= & %s & %s \\\\\n",$1,$2,$3,$4}
FNR==4 {
printf "\\center\n"
printf "\\begin{tabular}{r|c|l}\n"
printf "%s %s %s & & %s \\\\\n",$1,$2,$3,$4
}
FNR==5 { printf "%s & %s & %s \\\\\n",$1,$2,$3 }
FNR==6 {
printf "%s & %s & %s \\\\\n",$1,$2,$3
printf "\\end{tabular}\n"
printf "\\end{center} \\\\\n"
}

Regards,

Ed.
