LoggerBinary (logger_binary v0.1.0)

A custom Logger formatter for handling binary data.

This formatter is designed to correctly format binary messages. It converts non-printable binary data into a hexadecimal string representation and can optionally add a directional indicator ("< " or "> ") when needed.

Features

  • Formats binary messages as uppercase hexadecimal strings.
  • Prepends formatted binary messages with a directional indicator if the :direction metadata is present. Supported values for the :direction metadata are :in and :out.
  • Uses the default Logger format for all other types of messages (e.g., printable strings and charlists).

Direction Indicator

You can add the :direction metadata to your log messages to indicate if the binary data is an incoming or outgoing message:

Logger.debug(<<0x01, 0x02, 0x03>>, direction: :in)
# Logs: "[debug] < 01 02 03"

Logger.debug(<<0x01, 0x02, 0x03>>, direction: :out)
# Logs: "[debug] > 01 02 03"

Without directional metadata, it simply logs the formatted binary:

Logger.debug(<<0x01, 0x02, 0x03>>)
# Logs: "[debug] 01 02 03"
