 But what should happen if you change markup? What if a \bf is

 Marking differences in math is altogether a different story.

Yes, of course, I'll need to adjust manually in such cases.
But I'm already quite lucky, because with word-diff, the task was much
easier than I've ever hoped.

My intention is, to be prepared, if one of my colleagues, who are all used
to MS-Office, would ask for such a diff-document one day.
Now I'm able to generate such a document.
(My problem at work is, that I'm the only one not using MS-Office.)

[NTG-context] visualising evolution from one version to another

2006-08-06 Thread Peter Münster 
Hello,
if you know a bit MS-Word, then you have seen perhaps the feature, that
permits visualising differences between 2 versions of a document: added
text in red, and deleted text stroke out.

I would like to make something similar with ConTeXt: making a pdf-file from
doc-versionX.tex and doc-versionY.tex with added text in some colour and
deleted text displayed with \overstrikes{}.

Do you have some ideas, how to do that?

Cheers, Peter

You need a way to create a merged ConTeXt document from the two separate
files, perhaps using something like this:

 Thank you for this hint! It's exactly what I need. I've also found a shell
 version: wdiff
 But I still have one problem: I can't have a paragraph in \overstrikes.
 Is there perhaps something like \startoverstrikes ... \stopoverstrikes ?

Not that I know of. It should be possible to cook something up with
metafun and/or \starttextbackgrounds i guess, but I do not have a
ready-to-use solution for you.

Here is a little script, to show what I'm doing now:

#!/bin/bash
OLD=$1
NEW=$2
OUT=$3
shift 3
echo '\setupcolors[state=start]' $OUT.tex
echo '\long\def\startDeleted*#1\stopDeleted*{\overstrikes{#1}}' $OUT.tex
echo '\long\def\startAdded*#1\stopAdded*{\startcolor[blue]#1\stopcolor}' \
$OUT.tex
wdiff -w '\startDeleted*' -x '\stopDeleted*' \
-y '\startAdded*' -z '\stopAdded*' $OLD $NEW $OUT.tex
texexec $@ $OUT
