Let's say I have string like this:

let a = 'iHello<cr>World'

Now I can use it for a remap:

execute 'nnoremap a '.a

But in order to use it with normal!, I would have to convert <cr> to a literal newline. I know I can do this:

let b = escape(a, '<')

Now b is 'iHello\World'. But how can I parse it to become 'iHello\nWorld' (where \n is a literal linefeed character)

Instead of <cr>, use ^M in your string:

let a = 'iHello^MWorld'

You can insert this with <C-v>+<CR>, this is a graphical representation of a newline in vim.

It will work in those cases:

:execute "normal ".a
:execute "normal! ".a
:execute "nnoremap a ".a     (then press a in normal mode)

Now if your want to make it work in the following case:

:execute "nnoremap a :normal! ".a     (then press a in normal mode)

You need to use the following (c.f. this answer):

let a = 'iHello<C-v><CR>World<CR>'

    You got to it before me. :P – Tumbler41 Jun 3 '16 at 14:46
  • Well, it won't work with :normal since the ^M will execute it. You need ^V^M in the string to use it with :normal. – Antony Jun 3 '16 at 14:47
  • How so? I made it work... Can you add some details please? – nobe4 Jun 3 '16 at 14:48

    @FizzyTea: my bad, you're right, I didn't see the second example, let me update that. Thanks for the detail :) – nobe4 Jun 3 '16 at 14:53

    I was really confused about ^M, but then I noticed, that ^M is actually the graphical representation of a carriage return in vim, not necessarily a newline, maybe you should edit that. – hgiesel Jun 3 '16 at 14:56
