CloseIt.vim

Smart, semi-automatic insertion of closing parentheses, braces, etc.

x = ((3 + 2) * (4 + 9<CURSOR> <CloseIt>

x = ((3 + 2) * (4 + 9)<CURSOR> <CloseIt>

x = [(3 + 2) * (4 + 9)]<CURSOR>

When triggering CloseIt the last opening character without a matching closing character (before the cursor) will be located. If such a character can be found the corresponding closing character will be inserted.

If the opening character is at the end of a line a line break will be inserted as well.

int main () {
	return 0;<CURSOR>

<CloseIt>

int main () {
	return 0;
}<CURSOR>

Strings are handled automatically: if you trigger CloseIt while editing a string only opening characters in other strings are considered and vice versa.

Note: This can get wonky with multi-char string delimiters (""") and nested delimiters ("Foo 'bar' baz").

Configuration

Create an insert mode binding for <Plug>CloseIt.

imap <S-SPACE> <Plug>CloseIt

CloseIt uses matching pairs defined in &matchpairs, usually set by a file type plugin. But you can easily define your own global or buffer local pairs.

set matchpairs="<:>"
setlocal matchpairs="^:$"
