F#实例语法 [英] F# instance syntax

问题描述

您在F#中用于成员声明的指示器是什么?我更喜欢

member a.MethodName

这是很多字母，否则使用 x .

解决方案

我几乎总是使用x作为 this 实例的名称.除了它比其他选项短之外，没有任何逻辑可言.

我看到的选项是:

member x.Foo     // Simply use (short) 'x' everywhere
member ls.Foo    // Based on type name as Benjol explains
member this.Foo  // Probably comfortable for C# developers
member self.Foo  // I'm not quite sure where this comes from!
member __.Foo    // Double underscore to resemble 'ignore pattern' 
                 // (patterns are not allowed here, but '__' is identifier)

基于类型名称的选项在某种意义上是有意义的(当在类型内部嵌套对象表达式时很好)，但是我认为为每个类型名称找到合理的2/3缩写可能非常困难. /p>

What indicator do you use for member declaration in F#? I prefer

member a.MethodName

this is to many letters and x is used otherwise.

解决方案

I do almost always use x as the name of this instance. There is no logic behind that, aside from the fact that it is shorter than other options.

The options that I've seen are:

member x.Foo     // Simply use (short) 'x' everywhere
member ls.Foo    // Based on type name as Benjol explains
member this.Foo  // Probably comfortable for C# developers
member self.Foo  // I'm not quite sure where this comes from!
member __.Foo    // Double underscore to resemble 'ignore pattern' 
                 // (patterns are not allowed here, but '__' is identifier)

The option based on the type name makes some sense (and is good when you're nesting object expressions inside a type), but I think it could be quite difficult to find reasonable two/three abbreviation for every type name.
