Subject: Re: rename_rev.pl script for reviewing renames

I've added the some flags:
	-e : gets executed on old lines
	-ea: executed on everything
	-nc: strips one line comments

So say you have a patch that adds parenthesis around a bunch of macros
like this:
http://marc.info/?l=linux-kernel&m=129685142419550&w=2

Then you can just type:
cat /home/dcarpenter/tmp/html23/parens.patch | \
	./rename_rev.pl -e 's/(define \w+) (.*)/$1 ($2)/'

Or if you have a camel case script that changes "ThisVariable" to
"this_variable".  Then the command would be:
git show c659c38 | ./rename_rev.pl -ea '$_ = lc' -ea 's/_//g'
Which changes everything to lower case and strips out all the
underscores.  You might want to combine it with some other flags:
git show c659c38 | ./rename_rev.pl -nc \
	-e 's/TLanPrivateInfo/struct tlan_priv/' \
	-e 's/TLanList/struct tlan_list/' \
	-ea '$_ = lc' -ea 's/_//g'

What I would like is if there was some way to ignore changes which just
introduced new lines, but didn't affect runtime behavior.  I'm not sure
how to do that.

dan carpenter
