@hackage monadlog0.1.1.1

This package is a fork of great `monad-log`, as the original author is unreachable.

It provides a mtl style MonadLog class and a concrete monad transformer LogT, the main difference between this package and monad-logger are:

• Base monad has to be an instance of MonadIO.

• Parametrized logging environment for extensibility.

• Basic logging environment type(Label,Loc,NameSpace,ThreadId) are included, and you can easily make your own.

• JSON logging built-in.

• default to fast-logger backend, with good stdout and file support.

If you are an application author, you can use LogT transformer, it's just a specialized reader monad to inject `Logger env`.

If you are a library author, you should do following two things:

• make your monad stack an instance of MonadLog, usually you can do this by embedding `Logger env` into your monad's reader part.

• provide a default formatter, and API to run with customized formatter.
