Update snippet 'Building Strings'
Title
Passcode
Description
When sprintf and String.concat is either too slow or not really what is needed, one can use System.Text.StringBuilder. This snippet makes working with StringBuilder much more convenient and the resulting code more succint.
Source code
open System open System.Text // Too lazy to use ToString(). let Out x = x.ToString() type Object with member this.Out : string = this |> Out // Too lazy to use foo.Append(bar). let (++) (left : System.Text.StringBuilder) (right : 't) : System.Text.StringBuilder = left.Append right // Too lazy to use foo.Append(bar) |> ignore let (+=) (left : System.Text.StringBuilder) (right : 't) : unit = left ++ right |> ignore // Let's see what we are left with. let source = let mutable x, y, a, b = (*[omit:(...)]*)(0, 0, 0, 0)(*[/omit]*) let foo, bar, baz, waz, zup, bla = (*[omit:(...)]*)("foo", "bar", "baz", "waz", "zup", "bla")(*[/omit]*) let s = new StringBuilder() // ... while x < y do if a > b then s += bla // ... // ... s ++ foo ++ bar ++ baz ++ waz ++ zup |> Out
