I would like to to delete line from L1 to L2, I try to script
that but obviously commands are different for a script. What
is the right thing to do ?
Well, if L1 and L2 represent fixed line numbers, such as "line 24
through line 38", you can just put
24,38d
in your script. Quick, easy, clear...the way to go.
If L1 and L2 represent strings/regexps for finding a given line,
you can use
let oldWS=&wrapscan
set wrapscan
$/L1/,/L2/d
let &wrapscan=oldWS
You can skip the 'wrapscan' stuff if you already have 'wrapscan'
enabled (most folks do, only to turn it off selectively on an
as-needed basis), or if you know that the L1 won't happen on the
first line of the file. In the second case (L1 isn't on the 1st
line of the file), you can just do
1/L1/,/L2/d
It basically is searching from line 1 for the first instance of
L1, and then deleting through the first instance of L2 that
follows L1.
Just a few ideas. I can expound on their magic further if you
need, but you can start by reading in the help under
:help :range
:help :d
which should get you off to a good start.
