how to stop vim moving javascript object keys to column 0 -

when typing javascript object literals, such as:

foo = {     bar: baz }; 

vim thinks "bar:" c-style label , moves column 0.

how stop this?

try :set cinkeys-=:.

label indentation cannot controlled cinoptions. quote :help indent

vim puts line in column 1 if:

• it starts '#' (preprocessor directives), if 'cinkeys' contains '#'.
• it starts label (a keyword followed ':', other "case" , "default").
• any combination of indentations causes line have less 0 indentation.

(emphasis mine)

however, cinkeys specifies keys trigger reindenting in insert mode. removing : cinkeys, vim no longer reindent on inserting :.

but aware manual re-indenting via = will still break layout.
