How do you use tokens instead of strings for targets?

Question

I found that you can use tokens instead of strings for target names in FAKE scripts. Could you translate my sample script into one that uses provided operators?

// include Fake lib
#r "packages/FAKE/tools/FakeLib.dll" open Fake

// Targets 
Target "Clean" (fun _ ->
    CleanDir "./build/")

Target "Default" (fun _ ->
    trace "Hello World from FAKE" )

// Dependencies 
"Clean"   ==> "Default"

// start build 
RunTargetOrDefault "Default"

Answer 1

You can do this with the following.

open Fake

// Targets 
Target?Clean (fun _ ->
    CleanDir "./build/")

Target?Default (fun _ ->
    trace "Hello World from FAKE" )

// Dependencies 
"Clean"   ==> "Default"

// start build 
RunTargetOrDefault?Default

For reference it might be worth having a look at other uses dynamic operator for F# here. So you get a better feel for what it is doing.
