Changelog

Version 0.8.2

• fix license in source code files (Mozilla Public License Version 2.0)

Version 0.8.1

• General cleanup

• Some refactoring (removed MakeLogging functor)

• Relax ppx_deriving dependency requirements.

• Switch to Mozilla Public License 2.0

• Minimal version of OCaml is not 4.07

Version 0.7

• added tree_to_yojson function

• added level_of_string to Logging

• logger level is no more option type (NoLevel takes the role of None)

• fix json formatter

Version 0.6

• Added more options to file handlers (automatic timestamps and/or versioning of file names)

• Added CliErr handler to output to stderr

• modified handlers type so that fully custom handlers can be instantiated

• cleaned module API

• log items contains a timestamp

Version 0.6.2

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

version 0.5.1

• log_level type is direcly accessible from Easy_logging and Easy_logging_yojson modules

version 0.5.2

• more file_handler options (timestamp, versioning)

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.
