Development.IDE.Types.Logger

This is a compatibility module that abstracts over the concrete choice of logging framework so users can plug in whatever framework they want to.

Documentation

data Priority

Constructors

Telemetry

Events that are useful for gathering user metrics.

Debug

Verbose debug logging.

Info

Useful information in case an error has to be understood.

Warning

These error messages should not occur in a expected usage, and should be investigated.

Error

Such log messages must never occur in expected usage.

Instances

Bounded Priority

Methods

newtype Logger

Note that this is logging actions _of the program_, not of the user. You shouldn't call warning/error if the user has caused an error, only if our code has gone wrong and is itself erroneous (e.g. we threw an exception).
