Yes, you can give other relative ranges.  Note that it breaks down as

   :g/pattern/action_to_perform_on_matching_lines

where action happens to be

   <range>s/foo/bar/

(prefixed with "sil!" as previously detailed) and where <range> 
happens to be "search backwards for pattern A, through searching 
forwards to pattern B".  For the line above/below version, you

Oh, I missed the paragraph bits...if they're blank-line separated 
paragraphs, you can use the range '{,'} as in

   g/interesting/sil! '{,'}s/^/XXX

You can read about those marks at

   :help '{
   :help '}

When I do that, it still doesn't fork (although I can tell I am not getting
local scripts because the font that is set in my .vimrc is no longer being
used.)

I managed to "solve" my problem by downloading gvim 7.3 and using that instead
of the 7.2.284 that comes with Mandriva.  When I download it myself and compile
it myself, it forks.

How to find start/end of char-wise visual selection?


Hi, this is for Vim7.3.. Looking up docs for line(), it says that
arg='.' will give you cursor position, and 'v' will give you beginning
of visual selection when in visual mode, and '.' will give you the end
of it. For column, col() should be used, but there's no 'v' arg for it.

So, how can I do this? Let's say I have a char-wise selection from
column 10 to 20, how can I get numbers 10 and 20? -ak

Yeah, I remember, I wondered about it too. I even thought about creating
a patch, but didn't so far, because you can easily get the column using
the getpos() function together with the marks '< for start and '> for end
of visual selection. For my plugin NrrwRgn, I use getpos("'>") for the line
and virtcol("'>") for the virtual column of the end of the visual selection
(and the same for the start of the visual selection).

> So, how can I do this? Let's say I have a char-wise selection from

echo "start at line " getpos("'<")[1] " column: " virtcol("'<")
echo "end at line " getpos("'>")[1] " column: " virtcol("'>")

Christian

Change background colour to specific colour

I have been googling for a way to change the background colour of VIM
to a specific colour. For example, I'd like it to be #c6c0d7. Is there
no way to do such a thing? I only see references to using
already-configured colours in VIM.

Thanks.

For the gui version, this is possible. See :h gui-colors

So this should work:
:hi Normal guibg=#c6c0d7

For the terminal version, this depends on your terminal and vim has no
control over those settings.

Although you don't have as much control with a color terminal, you can
still use this basic mechanism: e.g.,
:hi Normal ctermbg=blue
You can also use color numbers.

:help cterm-colors
:help xterm-color

1. Does Special have a highlight definition different than the
surrounding text?
2. Is this the only syntax rule you are applying? There are precedence
rules in :help :syn-priority

I have this mapping in my .vimrc to help debug syntax files:

  nmap <F10>
        \ :echo '<'.synIDattr(synIDtrans(synID(line('.'),col('.'),
1)),'name').'> from:' <bar>
