DoTrace
Provides a trace/1 macro to trace function calls at runtime, mimicking Clojure's dotrace output.
A response to a LinkedIn post.
Example usage
iex> defmodule Math do
def factorial(0), do: 1
def factorial(n) when n > 0, do: n * factorial(n - 1)
end
iex> require DoTrace
iex> DoTrace.trace(Math.factorial(5))
