I am trying to emulate readline keybindings in insert and command-line modes (for example, <C-u> for deleting from cursor position to beginning of the line, or <C-w> to delete previous word). The readline action kill-line deletes from the current cursor position to the end of the line, and it is usually bound to <C-k>. I have managed to emulate it in insert mode with

inoremap <Plug>(i_kill-line) <Esc>lC
imap <C-k> <Plug>(i_kill-line)

How could I do something similar in command-line mode?

    I understand you may still want to do things as you describe but are you familiar with the command-line window? It's a great way to do command-line editing. You can use the full power of Vim rather than a smattering of Vim-like keystrokes.

  • C-u and C-w should already work insert mode. At any rate for command-line mode you need cnoremap, and as BLayer says the command-line window makes editing even nicer.

    Thank you for your answers! I am aware of the command-line window and I should probably use it more. However, I like to have the same basic keybindings in the main places where I can type (mainly Bash, Vim and fzf window) because that makes it easier to learn them and use them mechanically. <C-k> was recently added to my vocabulary, so I wanted to make it available in Vim.

    I had the same question (why I'm here): I wanted to have the same bindings in VI, terminal, and Mutt. it bothers me a bit that this doesn't seem to be a more popular question. makes me think there's something wrong with wanting to do this!

Use combination of :h c_CTRL-\_e, :h getcmdline() and :h getcmdpos():

func! KillLineToEnd()
    return strpart(getcmdline(), 0, getcmdpos()-1)
endfunc
cnoremap <C-k> <C-\>eKillLineToEnd()<CR>
