The only gotcha with this is that a paragraph must have a blank
line before & after it. I've gotten stung doing this exact format
of command because the match was in the first/last paragraph of the
document. So you need to also ("\|") accept a match of the beginning
of the file ("\%^") and end of the file ("\%$")
:g/aaa/?^$\|\%^?,/^$\|\%$/s:aaa:bbb:g
As Sven says, it's ugly. But it's doable and fairly concise in what
you're describing:
Find all the "aaa"
Starting there, search backwards to the previous blank line or BOF
From there, search forwards to the next blank line or EOF
Substitute "aaa" → "bbb" on all the lines of that range
Very interesting.
Thank you for that explanation Tim.
Alternatively, you could hack it with normal mode, something like
:g/aaa/norm vip:s//bbb^V^M
where ^V^M is a control-V followed by a control-M (which makes this
nasty to put in a mapping or vimrc). This works because vim knows
that a "paragraph" is bounded by empty lines *or* BOF/EOF and does
the ugly work for us.
ACK
Would it be worth while to include word boundaries \< and \> so that you
don't accidentally get a sub-string?
:g/aaa/?^$\|\%^?,/^$\|\%$/s:\<aaa\>:bbb:g
Also, is there any way to group the first "aaa" so that it could be
(back) referenced in the substitution? }:-)
I can't imagine doing this in pretty much any other text editor
without typing a LOT more.
