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

" ftplugin/c/c_snippet.vim
inoremap <expr> <buffer> ; getline('.')[col('.')-1:-1]=~')$' ? '<right>;' : ';'

This version shall not pose problems with for if your snippets engine expands it into

for (...|) {
   <+code+>
}<++>

If the open bracket is on a newline, it will mess things up.

You could easily change the regex to '"\=)\+$' to answer your initial question.

inoremap <expr> <buffer> ; getline('.')[col('.')-1:-1]=~'"\=)\+$' ? '<end>;' : ';'

However, I don't think it's a good idea. In that case, the mapping for <bs>will be:

inoremap <expr> <buffer> <bs> getline('.')[:col('.')-2] =~ '.*")\+;$' ? '<bs><c-o>F";' : '<bs>'
