Can I include /range/ in substitute pattern?
Pablo Contreras
I'm wondering if you gentlemen will be able to help me here.
Let's say I have
=====
john [<--current-line]
sells kites
=====
if I want to add bikes to John's sales I do
:/sells kites/s//\0 and bikes/
which is great because it saves me typing 'sells kites' in the pattern
the inclusion of just s//.......
tells Vim 'use the last pattern found as part of the search pattern.
hence I get:
=====
john
sells kites and bikes [<--current-line]
=====
how about this:
=====
john [<--current-line]
sells kites and bikes
=====
I decide I don't like the order in which John is selling. I want to change this order:
so I could do:
:/kites/s/\(kites\)\(.*\)\(bikes\)/\3\2\1/
then surely:
=====
john
sells bikes and kites [<--current-line]
=====
result. But I'm just wondering is there a shorthand way of re-type 'kites' in my search pattern.
so far I've tried:
:/kites/s/\(~\)\(.*\)\(bikes\)/\3\2\1/
which doesn't work because you can only use ~ on the right hand side of :subst
similarly
:/kites/s/\(&\)\(.*\)\(bikes\)/\3\2\1/
because & has to be on the right.
my previous trick:
:/kites/s//...... /
doesn't work here because I'm trying to match both 'kites' and 'and bikes'
Is this too ambitious?
Thanks in advance! Pablo.

If you had searched /kites/ first, I'd suggest <C-r>/ to paste the search register, but clearly that isn't what you're after. If you do it that way,
/kites
:s/\(<C-r>/\)\(.*\)\(bikes\)/\3\2\1/
would shorthand typing kites (Just in case I'm not being clear about the key sequence here, <C-r>/ means ctrl+r then '/', and these are two commands, one to search and one to substitute)
That works for your example on my machine.

love the name :)
(I was a big Kong fan in my time)
I think I wasn't explaining myself clearly.
Also I was a bit confused.
What I was trying to do was this: (AutoIt3 BASIC)
=====
Dim $K_MAINGUIWIDTH
$K_MAINGUIWIDTH = 320
..
GUICreate( "hello world!", 200, 100 ........
=====
say I'm interested in that string $K_MAINGUIWIDTH right at the top there
it's a GUI in AutoIt3
I was looking change the GUICreate to use $K_MAINGUIWIDTH instead of a set 200
I got confused because /RANGE/ and s// are different. The
/RANGE/s//NEW TEXT/ is a special case where Vim lets you use the
previously used pattern as the search pattern in the s//
In fact my replacement can be achieved in s// exclusively
you do:
1s/\(\_.\{-}\)\($K_MAINGUIWIDTH\)\(\_.\{-}\)200/\1\2\3\2/
ask Vim to go skip through the entire fie
\_.\{-}
until it matches $K_MAINGUIWIDTH
then keep going
\_.\{-}
until you match 200
then your substitute string you just put those things back
\1\2\3
then add your desired string
\2
Works for me!
Cheers, Pablo.

Oddly enough, I think in nearly 15 years of using this moniker, you're the first to notice that connection! :)

I think you can simplify this further. First, 1s is unnecessary, s on its own defaults to replacing only the first occurrence of a pattern (you need the /g flag to change that behavior) and like most commands operates on the current line only by default (you need a range larger than 1 to change that behavior).
The movements you're doing may also be a bit overkill, depending on the situation precisely; if you simply match on GUICreate instead of the 200 it will probably narrow the results to one of a few calls (since GUICreate isn't something I would expect to be called massively often) - then just use the /gc flag to confirm which ones need substitution over the whole file (or most of it).
Finally, \zs can simplify your substitution. It lets you define where the match actually starts *after* some other matching. So, Give this a go:
%s/^GUICreate.*, \zs200/$K_MAINGUIWIDTH/gc
Just hit 'y' or 'n' a few times as relevant.
Hope it helps!
