Should we also have a SpaceAfterColon? Or maybe just SpacesAroundColon to control both? And should those options be global? There's at least 4 different situations I can think of where the colon is used, and I don't think they all fit under the same setting:
- Type declaration in records and abstract members: (usually there's spaces around)
type T = {
A : int
B : string }
type IFoo =
abstract Prop : int
- Type annotations in return types: (usually there's spaces around)
let xs : int list = []
- Type annotations in arguments: (I've seen both spaces around, no spaces around, or just spaces after, I think the more common is the first one)
let replace from to (s:string) = s.Replace(from, to)
let replace from to (s: string) = s.Replace(from, to)
let replace from to (s : string) = s.Replace(from, to)
- Giving names to arguments in type declarations in abstract members: (usually there's no spaces around)
type IFoo =
abstract Foo : s:string * i:int -> unit

If we use SpacesAroundColon
, we have to implicitly assign value 0, 1, 2 and 3 for it. Using SpaceAfterColon is a bit easier.
And should those options be global?
How do we deal with locality? We may split options into categories e.g.
- Colons in type declarations (case 1 and 4)
- Colons in arguments' type annotations (case 2 and 3)
To be honest, I'm still puzzled about this option.

My desire is to have something like this https://github.com/icsharpcode/NRefactory/blob/master/ICSharpCode.NRefactory.CSharp/Formatter/FormattingOptionsFactory.cs#L46 where there are at least a few idiomatic styles to choose from.
Unfortunately there is no such style in F# (and functional programming) yet.

PageWidth is now 120 and SpaceBeforeColon is false, see FormatConfig.
