LeafSyntax

Create a ''failure'' treelog.LogTreeSyntax.DescribedComputation with -\/(description) as the value and a failure treelog.LogTreeSyntax.DescribedComputation with the given description.

import treelog.LogTreeSyntaxWithoutAnnotations._
import scalaz.syntax.show._

val leaf = 1 ~>! "One"
println(result.run.value)
// Will print: -\/("One") - note that the 'left' means ''failure'', and the contained value is the description, not the 1.

println(result.run.written.shows)
// Will print:
// Failed: One

Create a ''failure'' treelog.LogTreeSyntax.DescribedComputation using the given description function to generate a description for the tree node's label and for the DescribedComputations value (i.e. the value will be \/-(description(value)).

import treelog.LogTreeSyntaxWithoutAnnotations._
import scalaz.syntax.show._

val leaf = 1 logFailure (x => s"One - $x")
println(result.run.value)
// Will print: -\/("One") - note that the 'left' means ''failure'', and the contained value is the description, not the 1.

println(result.run.written.shows)
// Will print:
// Failed: One - 1

Create a ''success'' treelog.LogTreeSyntax.DescribedComputation with \/-(value) as the value and a success TreeNode with the given description.

import treelog.LogTreeSyntaxWithoutAnnotations._
import scalaz.syntax.show._

val leaf = 1 logSuccess "One"
println(result.run.value)
// Will print: \/-(1) - note that the 'right' means ''success''

println(result.run.written.shows)
// Will print:
// One

Create a ''success'' treelog.LogTreeSyntax.DescribedComputation with \/-(value) as the value and a success treelog.LogTreeSyntax.DescribedComputation using the given description function to generate a description for the tree node's label.

import treelog.LogTreeSyntaxWithoutAnnotations._
import scalaz.syntax.show._

val leaf = 1 logSuccess (x => s"One: $x")
println(result.run.value)
// Will print: \/-(1) - note that the 'right' means ''success''

println(result.run.written.shows)
// Will print:
// One: 1
