(10:52:48) Dan: know what would be cool?
(10:53:00) Dan: a stateful sed/grep tool (or wrapper around them)
(10:53:20) Dan: so i dont have to mess with awk and such
(10:53:21) Dan: something like this:

<old state>: <regex 1> <new state>
<new state>: <regex 2>//
<new state>: <regex 3> <old state>
(10:53:42) Dan: example, something ive wanted to do recently, i had text like this:

INFO: some log info
DEBUG: some log debug
INFO: Hex dump:
0001 0A0B0100 0A0B0100 0A0B0100  ..........
0002 0A0B0100 0A0B0100 0A0B0100  ..........
0003 0A0B0100 0A0B0100 0A0B0100  ..........

INFO: some log info
(10:53:53) Dan: I wanted to sanitize the output, so for example: 0001 0A0B0100 0A0B0100 0A0B0100  .......... would become 0001 <removed>
(10:54:03) Dan:  If i had a stateful regex tool, I could do this:
(10:54:09) Dan:
s1: "^INFO: Hex dump:$" s2
s2: " ([0-9A-F]{8} ){3}\.+$"/<removed>/
s2: "^$" s1
