Extrace is an Elixir wrapper for [Recon Trace](https://ferd.github.io/recon/recon_trace.html).
## Installation
The package can be installed by adding `:extrace` to your list of dependencies
in `mix.exs`:
```elixir
def deps do
[
{:extrace, "~> 0.3.0"}
]
end
```
## Examples
Set point:
```elixir
iex> Extrace.calls([{Enum, :take_random, fn _ -> :return end}, {Enum, :count, fn _ -> :return end}], 100, [scope: :local])
4
```
Note that the functions to be traced (`:take_random` and `:count` in the example above) can only be private if `scope: :local` is set.
One function executed:
```elixir
iex(2)> Enum.take_random([1,2,3,4], 200)
[2, 4, 3, 1]
18:42:10.834670 <0.183.0> Enum.take_random([1, 2, 3, 4], 200)
18:42:10.840212 <0.183.0> Enum.take_random(%{0 => 2, 1 => 4, 2 => 3, 3 => 1}, 4, [])
18:42:10.840949 <0.183.0> Enum.take_random(%{0 => 2, 1 => 4, 2 => 3, 3 => 1}, 3, [1])
18:42:10.841064 <0.183.0> Enum.take_random(%{0 => 2, 1 => 4, 2 => 3, 3 => 1}, 2, [3, 1])
18:42:10.841202 <0.183.0> Enum.take_random(%{0 => 2, 1 => 4, 2 => 3, 3 => 1}, 1, [4, 3, 1])
18:42:10.841330 <0.183.0> Enum.take_random(%{0 => 2, 1 => 4, 2 => 3, 3 => 1}, 0, [2, 4, 3, 1])
18:42:10.841440 <0.183.0> Enum.take_random/3 --> [2, 4, 3, 1]
18:42:10.841521 <0.183.0> Enum.take_random/3 --> [2, 4, 3, 1]
18:42:10.841606 <0.183.0> Enum.take_random/3 --> [2, 4, 3, 1]
18:42:10.841685 <0.183.0> Enum.take_random/3 --> [2, 4, 3, 1]
18:42:10.841959 <0.183.0> Enum.take_random/3 --> [2, 4, 3, 1]
18:42:10.842046 <0.183.0> Enum.take_random/2 --> [2, 4, 3, 1]
```
Another function executed:
```elixir
iex(4)> Enum.count([1,2,3,4])
4
18:42:27.383667 <0.183.0> Enum.count([1, 2, 3, 4])
18:42:27.383795 <0.183.0> Enum.count/1 --> 4
