Óg

Óg is a small collection of logger helper functions.

Installation

Add óg to your list of dependencies in mix.exs:

def deps, do: [{:og, "~> 0.2"}]

Summary

• log/1, log/2

• Inspects the data before logging it. For example, this can be helpful for avoiding the Protocol.UndefinedError when logging tuples for example.

• Optionally pass the log_level :debug, :info, :warn or :error which will respect the logger :compile_time_purge_level configuration setting - defaults to :debug when not passed.

• log_r/1, log_r/2

• Performs operations identical to Og.log/4 but returns the data in it's original form.

• Can be useful when one wants to log some intermediate data in the middle of a series of data transformations using the |> operator.

Example Usages

Og.log/1

Og.log(String.to_atom("test"))

Og.log/2

Og.log(String.to_atom("test"), :warn)

Og.log_r/1 , Og.log_r/2

%{first: "john", last: "doe"}
|> Map.to_list()
|> Enum.filter( &(&1 === {:first, "john"}))
|> Og.log_r()
|> List.last()
|> Tuple.to_list()
|> List.last()
|> Og.log_r(:warn)
|> String.upcase()
