Support for flow types

[martin-badin]

Hello,

please add support for flow types. Webpage is here.

Examples

type CustomType = {
    n: string,
    n2: Array<string>,
    ...
};

(n: string | boolean | number | Function | Object | any)
(n: { [string]:string })
(n: Array<string>)
(n: CustomType)

Thank you

Hi. This looks quite tedious... Flow syntax allows many many things, and it appears to be quite hard to highlight those precisely without breaking some of the normal JS highlighting.

The best I managed to come up with is the following:

The component would only highlight these types:

• number, Number
• string, String
• boolean, Boolean
• Function
• any, mixed, null and void

It would highlight these keywords:

• type, opaque, declare, Class
• $await, $Diff, $Exact, $Keys, $ObjMap, $PropertyType, $Shape, $Record, $Supertype, $Subtype, $Enum

It would highlight {| and |} as punctuation.

It would not highlight generic types, or custom types.

Here is what it would look like (those are examples from the documentation):

Would it be good enough?
