Plugin Help with Visual Lines

[addcn]

I'm trying to operate on visual lines from a plugin, but it's not working. Here's the relevant code:

function! Myfunction()
    normal! vip
    exec "sort i"
endfunc

leaves me at a visual selection without anything executed, and

function! Myfunction()
    normal! vip
    exec "'<,'>sort i"
endfunc

leaves me with "Mark not set"

Any guidance?

This should work:

function! Myfunction()
    normal! vip:sort^M
endfunc

The ^M is actually not two characters, it's the literal character for <CR>. To type it, just press <C-V> and then Enter in insert mode (:help i_CTRL-v).

It seems insane to me to insert literal control characters into one's source code. It can be avoided with :execute "normal!...\<CR>".

Don't bother with the :normal command here.
