Toggle paste and nonu in one keystroke

[Dotan Cohen]

Hi all, I am trying to write a function that will toggle the states
"paste && nonu" and "nopaste && nu". I cobbled a few things together
but although I figured this would be easy, it is eluding me. I need
some sort of persistent variable to test state mode. I also need it to
work in both Insert and Normal modes.

noremap <F2> PasteMode()
function! PasteMode()
  if exists(SOME_TYPE_OF_PERSISTENT_VARIABLE)
    unset PERSISTENT_VARIABLE
    set nopaste
    set nu
  else
    set PERSISTENT_VARIABLE
    set paste
    set nonu
  endif
endfunction



Thanks in advance for any advice.

This is way too complicated, :set allows to toggle values by itself
(:h :set-!), so this should work:

:nnoremap <f2> :set nu! paste!<cr>

Thanks, Christian, that is very helpful!

However I am having trouble with the Insert version. I am trying this code:
:inoremap <F2> <Esc>:set nu! paste!<cr>

However, when I press F2 in Insert mode I get the text <F2> inserted
into the document!

Also, I will have trouble with reentering Insert mode, because if I
use "i" or "a" then I will have troubles at the end or beginning of
text lines. Is there a workaround for that?

Thanks!

Well, by definition in paste mode, mappings aren't executed (:h 'paste')

:h i_CTRL-\_CTRL-O

That makes perfect sense! Thanks.

have a look at

  :help 'pastetoggle'

although this won't help you at resetting the 'number' option:

  :inoremap <F2> <Esc>:set nu! paste!<cr>
  :set pastetoggle=<F2>

Regards,
Jürgen

Thank you Jürgen. As you mention, though, that only solves half the issue!
