vim | replacement question
Hi all!
Another replacement question:
how can I replace all occurrence of a pattern except a given one, e.g.
the first or third?
the code for all occurrences I use is:
:%s/a.\{-}//g
Thanks in advance,
Nikos

I see that others have given the answer to the specific question you
asked, so I won't repeat that.
However, a related capability is to use the c flag (for confirm):
:%s/a.\{-}//gc

Hi,
another two questions:
1. I want to delete all text that has a specific pattern. I use the
following code with s command but I want to keep the \a character
in the beginning:
:%s/\a,\_.\{-}\/td\/tr/
To delete everything that matches a certain pattern
:%s/pattern//g
(i.e., replace by nothing). To keep something at the start, see
:help /\zs
:help /\@=
2.
how can I join lines that have non-numerical characters?
e.g.
153
Purdue
Canc Ct
1256
should be
153
Purdue Canc Ct
1256
Thanks in advance,

:%g/\D.*\n.*\D/join
i.e. join two successive lines, adding an intervening space, if
there is at least one non-digit anywhere in each of them.
Best regards,
Tony.
For 1 I came up with this:
:%s/\(\a\),\_.\{-}\/td\/tr/\1
about 2
:%g/\D.*\n.*\D/join
.* captures some numeric values in between. Maybe sth like this would
be better:
:%g/\D.*\n.*[^\d]\D/join
but this is not right.
Well, it all depends on what you want to do. If there are both digits
and nondigits on a single line, do you want to join it or not? Or does
it depend on whether the nondigits are or aren't whitespace?
I would suggest that you read the helpfile :help pattern.txt and
especially the part starting at :help pattern-overview and extending
over 150 lines or more.
Best regards,
Well that worked for me fine:
:%g/\D\n\D/join
You are right. Everything depends on what you want to do.
Another small question:
If you want to an empty line to the end of a file what does the trick?
I tried :,$s/\(.*\)/\1\n
but doesn't work
Thanks,
Nikos

To add an empty line at the end of the file
GoEsc
or in a script
normal Go^[
where ^[ is hit Ctrl-V hit Esc (replace Ctrl-V by Ctrl-Q if you use
Ctrl-V to paste the clipboard)
To remove an empty line at the end of the file
:if getline($) =~ '^\s*$' | $d | endif
(if the last line is all whitespace, remove it)
To remove any number of empty lines at the end:
:while getline($) =~ '^\s*$' | $d | endwhile
Best regards,
Tony.

To add an empty line at the end of the file GoEsc or in a script normal Go^[ where ^[ is hit Ctrl-V hit Esc (replace Ctrl-V by Ctrl-Q if you use Ctrl-V to paste the clipboard) Additionally, in a script, you can use :$put ='' to add empty lines at the bottom of the file To remove an empty line at the end of the file :if getline($) =~ '^\s*$' | $d | endif (if the last line is all whitespace, remove it) or alternatively: :/^\s*\%$/d To remove any number of empty lines at the end: :while getline($) =~ '^\s*$' | $d | endwhile or alternatively :%s/\_s*\%$ will remove all the trailing whitespace in the file. If you want to only remove truely blank lines (no whitespace in them) you can use :%s/\n*\%$/ So many ways to do the same thing. Strange that I like that ability in Vim, but abhor perl for the same reason. :) (maybe because I write vim one-liners as a use-once-and-dispose-of-it, and would grow to hate such opaque hacks if I had to go back and read them later, like one would have to do with perl code) -tim
