Suppose I have the following two lines in a function:

execute "normal! o"
execute "normal! S"

Is there a way to combine these so it is simpler, for example:

execute "normal! o<c-o>S"

It seems I need to 'escape' the <c-o> somehow.

    Yes, escape <c-o> with execute "normal! o\<C-o>S". See :help expr-quote which explains how double quoted strings work... – filbranden Jun 15 at 3:53

In execute parameters, you need to escape special characters sequences with \:

execute "normal o\<c-o>S"

But this will not let you in insert mode. You could add

startinsert

to force insert mode, but it will not respect autoindent. I don't know how to get around that.


You might as well go for a list of instructions:

normal! o
normal! S
startinsert

execute is no more needed, making the code quite clear.

  • sure, but wouldn't you need execute "..." if you're using any control sequence, such as in your first code line? – David542 Jun 15 at 5:23
  • @David542 Yes, indeed. I edited my post to make it clearer what I meant. – Biggybi Jun 15 at 5:40
  • You still want a bang on normal – D. Ben Knoble Jun 15 at 11:13
  • @D.BenKnoble I'm not sure I understand the doc but I believe in you. – Biggybi Jun 15 at 12:32
  • Well, typically it’s unlikely you want to use someone’s mapping for S when you do :normal S in a plugin—but without the bang, if I have nnoremap S anything it will take effect! Its like noremap for normal; it’s become something of a best-practice, and it’s good defensive programming. The idea is to use it unless you know you want to invoke a mapping via normal – D.
