Run global with range from within function

Question

I have a function somewhat like this:

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

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).

Answer 1

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

function Cont() range
  execute (a:firstline + 1) . "," . a:lastline . 's/^/\t\\ '
endfunction
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! >>"'
endfunction
1,3call MyFunction()
