# File-Only Logger

A simple logger that writes messages to log files only (not to the console).
Elixir's Logger Backends were abandoned in favor of Erlang's Logger handlers.

## Installation

Add `file_only_logger` to your list of dependencies in `mix.exs`:

def deps do
    {:file_only_logger, "~> 0.2.0"}

## Usage

Trying to log any message with severity less than the configured level will
simply cause the message to be ignored.

The configuration values for log level are:

- :all (default)
- :none
- [Logger.level()](

You may use file `config/runtime.exs` to configure the above log level:

import Config

config :file_only_logger, level: :info

#### Example

defmodule Log do
  use File.Only.Logger

  warning :error_occurred, {reason, file} do
    \n'error' occurred...
    Reason => '#{:file.format_error(reason)}'
    File => "#{Path.relative_to_cwd(file)}"\

defmodule Check do
  def log_warning do
    Log.warning(:error_occurred, {:enoent, __ENV__.file})

Check.log_warning() # will log these lines in the configured log file(s):

2023-11-15 19:05:19.763 [warning]
'error' occurred...
Reason => 'no such file or directory'
File => "lib/file/only/logger/ie.ex"
