Description
Provides deserialisation of logging configuration (loggers instantation and handlers parameters) from json, using ppx_deriving_yojson.
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

Logging module for OCaml.
Quick start :
open Easy_logging
logger = Logging.make_logger "my_logger" Debug [Cli Debug];;
logger#info "log_message";;
See documentation at https://sapristi.github.io/easy_logging/easy_logging
Changelog
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
Added RotatingFile handlers : log file rotation based on file size
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.
