Helpers for debugging & inspecting code flow

Quick Start

end

Summary

Inspect Flow

import InspectorGadget
1
|> inspect_flow
|> fn x -> x + 1 end.()
|> fn y -> y * 100 end.()
|> inspect_flow
#=> 13:34:21.997 [info]  inspect_flow: 1
#=> 13:34:21.997 [info]  inspect_flow: 200

Overloaded Pipe

use InspectorGadget.Pipe
1
|> fn x -> x + b end.()
|> fn y -> y * 100 end.()
|> inspect
#=> 13:42:24.250 [info]  1 |> fn(x) = 2
#=> 13:42:24.250 [info]  2 |> fn(y) = 200
#=> 13:42:24.250 [info]  200 |> inspect = "200"

Note that this prints in the order of evaluation, so nested expressions are expected occur in a different sequence than the code

1
|> fn(x, y) -> x + y end.(
  6 |> fn z -> z * 10 end.()
)
#=> 13:44:02.649 [info]  6 |> fn(z) = 60
#=> 13:44:02.649 [info]  1 |> fn(x, y) = 61
