Vim smart insert semicolon

Question

Is there a Vim plugin that can handle smart semicolon insertion, like the one in Eclipse?

Example (pipe character is insertion cursor):

foobar(|)
         


        

Answer 1

I use the following function and a mapping to insert a semicolon to the end of the line and to delete the remaning spaces:

imap <leader>. <C-R>=Semicolonfun()<CR>
fun! Semicolonfun() "{{{
  call setline(line('.'), substitute(getline('.'), '\s*$', ';', ''))
  return "\<End>"
endfunction "}}}

So if you have something like:

log.warning("you miss the |identifier")

Pressing . or ,. if you remap the leader, you get the following:

log.warning("you miss the identifier");|

Answer 2

inoremap <expr> ;<cr> getline('.')[-1:] == ';' ? '\<Nop>' : '<End>;<CR>'

The code above will check if there is ; at the end of the line.

If ; not exists, then it will add ; otherwise do nothing.

Answer 3

You should try Cosco.vim plugin.

Answer 4

For vscode vim users:

"vim.insertModeKeyBindings": [
      {
        "before": [";", ";"],
        "after": ["<Esc>","A",";"]
      },
    ],

I was inspired by romainl's answer above, but <C-o> seems have a switch problem in vocode vim, so just use <Esc> will work.

Answer 5

I use this mapping:

inoremap <leader>; <C-o>A;

It's not ; because I use semicolons often and in more than one context.

• <C-o> is used to input a single normal mode command.
• A; means "add a ; at the end of the line".

Answer 6

I want to do the same thing, I works on it whole night, tons of code, but at last, I got a simple solution.

inoremap ;<cr> <end>;<cr>

and if I am in a brace, I want to add a semicolon or a dot at the end, like this

foo({
  |
})

I press ;;<cr> or ..<cr> to do this

inoremap ;<cr> <end>;<cr>
inoremap .<cr> <end>.
inoremap ;;<cr> <down><end>;<cr>
inoremap ..<cr> <down><end>.
