Hi
I have obtained a lot of modifications to sources that have been
broadcasted on the net. The majority of these modications have been published
by means of a file created from the differences utility. I would like to take
the original paragraph from the difference file and substitute the new
paragraph in its place. Ideally I would like a program to take the original
file, then take a "difference file" and produce the updated file that was used
with the original file to produce the "difference file" in the first place. If
this is not possible could you sugest a macro for EDT $or TPU that would
select text in the normal way and then search for the first section of
selected text and replace it with the second.
Another point I would find of use is to be able to put a paragraph
of text into the search buffer in screen mode and search for a paragraph. For
instance use the "select key" then place the selected text in the search
buffer.
As far as I can see there is nothing of this kind in the
orange books, and the only way is to write something in tpu. I realise that it
would be faster mailing for the source code if it was only going to be used
once, but as more and more difference files are posted on the net, it would be
a useful program to have.
Keywords: Edit, EDT, TPU, Search, Replace, Difference
Yours Sincerly
Andrew Kidd.

You can get diff to produce a machine readable difference file with diff/slp. The output can be used to run edit/sum. Thus at the site A, you might do $ diff/slp/output=.upd file.old .new and send file.upd to site B. At site B, you can then generate file.new with $ edit/sum/update/output=.new file.old Charles Karney Plasma Physics Laboratory Phone: +1 609 243 2607 Princeton University MFEnet: Karney@PPC.MFEnet PO Box 451 ARPAnet: Karney%PPC.MFEnet@NMFECC.ARPA Princeton, NJ 08544-0451 Bitnet: Karney%PPC.MFEnet@ANLVMS.Bitnet CC: info-vax@KL.SRI.COM cnar15%uk.ac.strath.vaxa@ukacrl.bitnet KARNEY
