I have a function somewhat like this:

function! MyFunction()
    g/\v.(\n\n|\n*%$)/execute "normal! v{:call AnotherFunction()\<cr>"

Now I want to be able to pass a range to that function. The problem is… how can I add the range (a:firstline and a:lastline) before the g command?

I tried all the combinations I could think of (like execute a:firstline.','.a:lastline' 'g/...), but I can't get it to work (maybe because I already use execute in the global command).

From the documentation (:h function-range-example):

function Cont() range
  execute (a:firstline + 1) . "," . a:lastline . 's/^/\t\\ '
4,8call Cont()

You need to use execute to pass the variables to the g command.

In your case, this simplified example should work (at least it works here):

function! MyFunction()
    execute a:firstline . ',' . a:lastline . 'g/^/execute "normal! >>"'
1,3call MyFunction()

    Ah, you're right, thank you! I wasn't passing a range when calling the function and I assumed it would use the whole file in that case, but apparently it doesn't, so I thought it wasn't working when I tried doing that. Anyway, it's all good now. Thanks again. :)

  • Ah, but look, here's a more complicated example that doesn't work, maybe because there are quotes in the pattern: execute a:firstline . ',' . a:last line . 'g/\(\.\|!\|?\)\()\|]\|"\|'\)*\($\|\s\)/execute "normal! v(:call MyFunction()\<cr>"'. Any ideas?

  • Just a guess, can you try escaping the ' with \'? (otherwise I think it's worth another question ;) )

    Ok, I had already tried that and it didn't work, but after looking around some more I found out it's possible to escape characters by doing <c-v><esc> and then the character. And that works! Edit: wait! no, it doesn't, haha. I'll open another question then.
