Default translation for Erlang log messages.
Logger allows developers to rewrite log messages provided by OTP applications into a format more compatible with Elixir log messages by providing a translator.
A translator is simply a tuple containing a module and a function that can be added and removed via the Logger.add_translator/1
and Logger.remove_translator/1
functions and is invoked for every Erlang message above the minimum log level with four arguments:
min_level
- the current Logger levellevel
- the level of the message being translatedkind
- if the message is a :report
or :format
message
- the message to format. If it is :report
, it is a tuple with {report_type, report_data}
, if it is :format
, it is a tuple with {format_message, format_args}
.The function must return:
{:ok, chardata, metadata}
- if the message translation with its metadata{:ok, chardata}
- the translated message:skip
- if the message is not meant to be translated nor logged:none
- if there is no translation, which triggers the next translatorSee the function translate/4
in this module for an example implementation and the default messages translated by Logger.
