how to stop vim moving javascript object keys to column 0

When typing javascript object literals, such as:

foo = {
    bar: baz
};

vim thin开发者_JAVA技巧ks "bar:" is a C-style label and moves it to column 0.

How do I stop this?

Try :set cinkeys-=:.

Label indentation cannot be controlled by cinoptions. To quote from :help indent

Vim puts a line in column 1 if:

• It starts with '#' (preprocessor directives), if 'cinkeys' contains '#'.
• It starts with a label (a keyword followed by ':', other than "case" and "default").
• Any combination of indentations causes the line to have less than 0 indentation.

(Emphasis mine)

However, cinkeys specifies which keys trigger reindenting in insert mode. By removing : from cinkeys, vim will no longer reindent on inserting :.

But be aware that manual re-indenting via = will still break your layout.
