Description

Logging infrastructure inspired by the Python logging module. The aim of this module is to provide a quick and easy to use logging infrastructure.

It has the following features :

  • one line logger creation
  • log messages printf style, or [string] or [string lazy_t]
  • tree logging architecture for light configuration
  • handlers associated to each logger will format, filter and treat the message independantly.
  • use the infrastructure with your own handlers with the [MakeLogging] functor.
  • use tags to add contextual information to log messages

Changelog

Version 0.4

  • printf style logging is now the default

  • simplifed configuration in case of multiple loggers (and closer to the python module) : the loggers form a tree (based on their name, dots indicating descendence)

    • log items are passed to the handlers of a logger’s ancestors (so that few handlers need initialisation) (possible to override)

    • loggers inherit the level of their ancestor if not set explicitely

  • an additional package easy_logging_yojson provides initialisation of loggers from the json format (with ppx_deriving_yojson), so that configuration can be fully done outside the code.

Version 0.5

  • Renamed the Default_handlers module to handlers

  • tag type in Handlers is now string (was unit)

  • added the possibility to add filters to handlers

  • added tag_generator feature to loggers, to automatically add tags to all messages passed to a logger
